Cause-related marketing, defined as a firm’s communication activities designed to promote a consumer good or service by including an offer to contribute a specified amount to a designated nonprofit cause, has become a preponderant practice. In tandem with the development of CrM activities, criticism of CrM has increased; critics note that some CrM claims mislead consumers regarding their purchases’ donative impact. Critics such as consumers and nonprofit advocates are using ad parodies, noncommercial messages that mimic an actual advertisement. In this (...) context, the study investigates how these ad parodies can result in a detrimental impact on consumers’ perceptual and behavioral evaluations of the sponsoring brand. By implementing a tightly controlled experiment comparing actual CrM campaigns and CrM parodies, the author shows that the detrimental effects of CrM parodies on brand attitude and word-of-mouth valence can be explained by greater skepticism toward the firm’s sincere and altruistic motivations. In addition, the author shows that a robust asymmetry emerges in which CrM ad parodies damage perceptual and behavioral evaluations of brands more than actual CrM campaigns improve them. The authors replicate the results for two kinds of critics and two types of brands. The results provide useful implications for theory and practice, documenting the backfire effect of poorly designed CrM, which may urge brands to move toward more self-regulation of CrM practices.

Building from an interactionist view of ethics, this study sought to integrate individual and contextual factors for understanding ethical perceptions in teams. Given the proximal nature of team members, this study specifically explored how individuals comparatively evaluate their own ethical behaviors and team members’ ethical behaviors to arrive at a perception of ethical person–group fit within a team. Grounding our theoretical arguments in relational schemas theory, we demonstrate that interpersonal ethical perceptions can have distal impacts on perceptions of team functioning. (...) The results support the hypotheses that a perceived ethical incongruence between the self and other team members negatively influenced perceptions of relationship conflict and ultimately information sharing. By exploring individual and team level aspects of ethics concurrently, we contribute to a deeper understanding of contextual forces in ethics through an interactionist approach. (shrink)

Many organizations offer their employees the opportunity to voice their opinions about work-related issues because of the positive consequences associated with offering such an opportunity. However, little attention has been given to the possibility that offering voice may have negative effects as well. We propose that negative consequences are particularly likely to occur when employees perceive the opportunity to voice opinions to be “pseudo voice”—voice opportunity given by managers who do not have the intention to actually consider employee input (i.e., (...) managerial disregard). The effects of this kind of deception were examined by means of a survey among employees (N = 137) and managers (N = 14) of a Dutch healthcare organization. We hypothesized and found that perceived pseudo voice led to reduced voice behavior and, as a result, increased intragroup conflict. These results imply that while offering voice opportunity is mostly seen as an effective management strategy, negative effects are likely to occur when a manager is perceived to try to deceive employees by pretending to be interested in their points of view.

Traditional Africans teach ubuntu principles of communality, mutual respect, caring and so forth, but they do not walk the talk with regard to the treatment of widows. In the footsteps of Jesus of Nazareth, Christian communities preach unconditional love, especially for the poor, marginalised and vulnerable. Implementation is, however, grossly lacking in respect of the treatment of widows. There is thus an apparent deliberate uncaring, disrespectful, discriminatory, impolite and unjust treatment of widows in African communities in spite of the ubuntu (...) values and Christian teaching that emphasise love and caring, especially towards the grieving and thus vulnerable widows. Widows seem to be neglected and even oppressed in our time. The aim of this research is to critically examine African traditional widowhood rites and practices with special reference to the comfort or pain to which they subject African widows. The research further aims to examine the behaviour of some African Christians belonging to three congregations of one mainline church to determine whether their treatment of widows resonates with Jesus’ teaching regarding the requisite care of widows. The issue of widowhood in Africa, in terms of the apparent plight of these bereaved and grieving women, needs to be urgently addressed for change in the 21st century. A critical literature study of relevant sources and a newspaper article will be used for this research. My personal experiences and continuing observation as an insider will also inform the research in useful ways. (shrink)

Emotions are a core factor of learning. Studies have shown that multiple emotions are co-experienced during learning and have a significant impact on learning outcomes. The present study investigated the importance of multiple, co-occurring emotions during learning about human biology with MetaTutor, a hypermedia-based intelligent tutoring system. Person-centered as well as variable-centered approaches of cluster analyses were used to identify emotion clusters. The person-centered clustering analyses indicated three emotion profiles: a positive, negative and neutral profile. Students with a negative profile (...) learned less than those with other profiles and also reported less usage of emotion regulation strategies. Emotion clusters identified through spectral co-clustering confirmed these results. Throughout the learning activity, emotions built a stable correlational structure of a positive, a negative, a neutral and a boredom emotion cluster. Positive emotion cluster scores before the learning activity and negative emotion cluster scores during the learning activity predicted learning, but not consistently. These results reveal the importance of negative emotions during learning with MetaTutor. Potential moderating factors and implications for the design and development of educational interventions that target emotions and emotion regulation with digital learning environments are discussed.

In 2017, the blockade of Qatar Gulf states caused a plethora of effects on the country. This paper sought to examine the resulting threat effects of this blockade in terms of lowered self-esteem and well-being, and the potential buffering effects of an overarching identity. Using self-report questionnaire data from Qatari secondary school students, multiple moderated mediation models investigated the predictive effects of youngsters’ perceived threat, via self-esteem, on their well-being, and the mitigating roles herein of, respectively, national, Gulf region, and (...) Arab identity. Perceived threat was indeed related to lower well-being via lower self-esteem, and this relationship was equally strong for those low and high in social identity. In terms of the three facets of identity, the overarching Gulf identity seems the most predictive, and it even buffers the negative relationship between threat and reduced self-esteem. (shrink)

Rhythm perception involves strong auditory-motor connections that can be enhanced with movement. However, it is unclear whether just seeing someone moving to a rhythm can enhance auditory-motor coupling, resulting in stronger entrainment. Rhythmic priming studies show that presenting regular rhythms before naturally spoken sentences can enhance grammaticality judgments compared to irregular rhythms or other baseline conditions. The current study investigated whether introducing a point-light figure moving in time with regular rhythms could enhance the rhythmic priming effect. Three experiments revealed (...) that the addition of a visual cue did not benefit rhythmic priming in comparison to auditory conditions with a static image. In Experiment 1, grammaticality judgments were poorer after audio-visual regular rhythms compared to auditory-only regular rhythms. In Experiments 2 and 3, there was no difference in grammaticality judgments after audio-visual regular rhythms compared to auditory-only irregular rhythms for either a bouncing point-light figure or a swaying point-light figure. Comparison of the observed performance with previous data suggested that the audio-visual component removed the regular prime benefit. These findings suggest that the visual cues used in this study do not enhance rhythmic priming and could hinder the effect by potentially creating a dual-task situation. In addition, individual differences in sensory-motor and social scales of music reward influenced the effect of the visual cue. Implications for future audio-visual experiments aiming to enhance beat processing, and the importance of individual differences will be discussed. (shrink)

The aim of this article is to critically build on Justin Biddle and Anna Leuschner’s characterization of epistemologically detrimental dissent in the context of science. We argue that the presence of nonepistemic agendas and severe nonepistemic consequences offers neither necessary nor sufficient conditions for EDD to obtain. We clarify their role by arguing that they are contingent enabling factors, not stable difference-makers, in the production of EDD. We maintain that two stable difference-makers are core to the production of EDD: (...) production of skewed science and effective public dissemination. (shrink)

While dissent is key to successful science, it is not always beneficial. By requiring scientists to respond to objections, epistemically detrimental dissent (EDD) consumes resources that could be better devoted to furthering scientific discovery. Moreover, bad-faith dissent can create a chilling effect on certain lines of inquiry and make settled controversies seem open to debate. Such dissent results in harm to scientific progress and the public policy that depends on this science. Biddle and Leuschner propose four criteria that (...) draw on inductive risk as a method for separating this EDD from beneficial dissent while de Melo-Martín and Intemann reject this approach for failing to capture paradigmatic instances of EDD. Against de Melo-Martín and Intemann’s objections, I propose the inductive risk account can be saved and strengthened through the following modifications: (1) removing the requirement that the four conditions of EDD be jointly satisfied, (2) requiring that each criterion be measured as a matter of degree rather than as a binary, and (3) requiring that the four criteria are measured holistically. These modifications not only mitigate the criticisms but produce five benefits over Biddle and Leuschner’s account, including: (1) capturing paradigmatic instances of EDD, (2) reflecting the degree to which an instance of EDD is problematic, (3) capturing the interactions between criteria, (4) avoiding legitimizing inappropriate dissent, and (5) reflecting changes to the epistemic standing of dissent. As such, I argue that the modified IndRA provides a powerful tool for identifying EDD and strengthening science. (shrink)

The influence of background music on cognitive functions is still a matter of debate. In this study, we investigated the influence of background music on executive functions (particularly on inhibitory functions). Participants completed a standardized cued Go/NoGo task during three different conditions while an EEG was recorded (1: with no background music, 2: with relaxing or 3: with exciting background music). In addition, we collected reaction times, omissions, and commissions in response to the Go and NoGo stimuli. From the EEG (...) data, event-related potentials (ERPs) were calculated for the Go and NoGo trials. From these ERPs, the N2 and P3 components were specifically analyzed since previous studies have shown that these components (and particularly the Go-NoGo difference waves) are strongly associated with inhibitory functions. The N2 and P3 components of the difference waves (N2d and P3d) were used for statistical analyses. The statistical analyses revealed no differences between the three conditions in terms of amplitudes and latencies of the N2d and P3d components. In addition, reaction times, omissions, and commissions were comparable across all conditions. Our results suggest that in the context of this paradigm, music as background acoustic stimulation has no detrimental effects on the performance of a Go/NoGo task and neural underpinnings. (shrink)

In response to a series of allegations of scientific misconduct in the 1980’s, a number of scientific societies, national agencies, and academic institutions, including Harvard Medical School, devised guidelines to increase awareness of optimal scientific practices and to attempt to prevent as many episodes of misconduct as possible. The chief argument for adopting guidelines is to promote good science. There is no evidence that well-crafted guidelines have had any detrimental effect on creativity since they focus on design of (...) research studies, documentation of research findings, assignment of credit through authorship, data management and supervision of trainees, not on the origin and evolution of ideas. This paper addresses a spectrum of causes of scientific misconduct or unacceptable scientific behavior and couples these with estimates of the potential for prevention if guidelines for scientific investigation are adopted. The conclusion is that clear and understandable guidelines should help to reduce the chance that flawed research will escape from our institutions. However, they cannot be relied upon alone to prevent all instances of scientific misconduct and should be regarded rather as one means of bolstering the integrity of the entire scientific enterprise.

Through the use of double task conditions, the sequence learning (SL) paradigm offers unique opportunities to study the relationships between learning and attention. In their original study, Nissen & Bullemer (1987) argued that a secondary tone-counting task prevents SL because it exhausts participants’ attentional resources. Other authors have instead suggested that the detrimental effects of tone-counting are due to scheduling conflicts between performing the main and secondary tasks rather than to attentional load. Frensch & Miner (1994), for instance, suggested (...) that the secondary task impairs sequence learning because it lengthens the response-to-stimulus interval (RSI) and hence makes it less likely for relevant contingencies to be represented together in short-term memory, — a condition for learning. Stadler (1995), on the other hand, argued that the secondary task introduces variability in the RSI and disrupts the organization of the sequence into chunks. Further, according to Willingham, Greenberg & Cannon Thomas (1997) manipulation of the RSI influences performance but not sequence learning.. (shrink)

Several studies have shown that physical exercise improves behavior and cognitive functioning, reducing the risk of various neurological diseases, protecting the brain from the detrimental effects of aging, facilitating body recovery after injuries, and enhancing self-efficacy and self-esteem. Emotion processing and regulation abilities are also widely acknowledged to be key to success in sports. In this study, we aim to prove that regular participation in sports enhances cognitive and emotional functioning in healthy individuals. A sample of 60 students, divided (...) into sportive and sedentary, were subjected to a neuropsychological tests battery to assess their overall cognitive abilities, verbal and graphic fluency, as well as their emotional awareness skills. Our results showed that sportive students performed better than sedentary ones in all cognitive tasks. Regarding emotional processing abilities, significant differences were found in the TAS-20 total score as well as in the Difficulty Describing Feelings subscale and the Difficulty Identifying Feeling subscale. Lastly, gender differences were found in the External-Oriented Thinking subscale. Overall, our findings evidence that PE has positive effects on cognitive functioning and emotion regulation, suggesting how sports practice can promote mental health and wellbeing. (shrink)

This article reports data collected from 385 performing arts professionals using the HEartS Professional Survey during the COVID-19 Lockdown 1.0 in the United Kingdom. Study 1 examined characteristics of performing arts professionals’ work and health, and investigated how these relate to standardized measures of wellbeing. Study 2 examined the effects of the lockdown on work and wellbeing in the respondents’ own words. Findings from Study 1 indicate a substantial reduction in work and income. 53% reported financial hardship, 85% reported increased (...) anxiety, and 63% reported being lonelier than before the crisis. 61% sought support on finances while only 45% did so on health and wellbeing. Multiple regression analyses, using the Mental Health Continuum-Short Form, Center for Epidemiologic Studies Depression Scale, Social Connectedness Scale, and Three-Item Loneliness Scale as outcome variables, indicate that perceived financial hardship was associated with lower wellbeing and higher depression and loneliness scores. Higher self-rated health was associated with higher wellbeing and lower depression scores. More physical activity before lockdown was associated with higher wellbeing and social connectedness scores, as well as lower loneliness scores, and an increase in physical activity during lockdown compared with before, as well as older age, were associated with higher wellbeing and social connectedness scores, and lower depression and loneliness scores. Thematic inductive analysis of 341 open responses in Study 2 identified five overarching themes characterizing the effects of Lockdown 1.0: lost or uncertain work and income, including canceled work, financial concerns, and uncertainties for the future; constraints of lockdown working, including challenges of working at home, struggles with online work and skill maintenance, and caring responsibilities; loss and vulnerability, including reduced social connections, lack of support, vulnerability, feelings of loss and grief, and concern for others; detrimental effects on health and wellbeing, including anxiety, low or unstable mood, poorer physical health, and lack of motivation; and professional and personal opportunities, including coping well or living more healthily, more time and less pressure, new possibilities and activities, enhanced social connections, and new skills. Lockdown 1.0 had profound effects on performing arts professionals, but our findings reveal some opportunities and compelling links between positive wellbeing and physical activity. (shrink)

This study examined the perceived effects of examination special centres on teaching and learning of English language and the quality of education in Nsukka Local Government Area, Enugu State, Nigeria. The study employed a descriptive survey design. All the 123 English language teachers from 31 secondary schools, five secondary school principals, three religious priests and three traditional leaders in Nsukka Local Government Area of Enugu State, Nigeria were sampled for the study. The researchers developed a 15-item-structured questionnaire for data collection (...) from the 31 teachers; while 3 structured interview questions were used to elicit responses from the principals, religious priests and traditional leaders. Mean and standard deviation were used to analyse the data collected with questionnaire; while the oral interview was analysed qualitatively through thematic analysis. The study revealed that examination special centres have detrimental effect on the teaching and learning of English language in secondary schools and the quality of education in Nsukka Local Government Area, Enugu State, Nigeria. It was recommended among others that private and public secondary schools, and tutorial centres that have been turned into examination special centres should be closed down by Enugu State Ministry of Education.

Various aspects of the relationship between ethical climate types and organizational commitment have been examined, although a relationship with the concept of bullying, which may be very detrimental to an organization, has not attracted significant attention. This study contributes to the existing research by taking the effects of bullying behaviour into consideration. The aim of this study is to explore the effects of bullying behaviour upon the relationship between ethical climate types and organizational commitment. It will be noted that (...) work-related bullying behaviour significantly mediated the relationship between instrumentality climate and two of the dimensions of organizational commitment. Significant relationships between ethical climate dimensions and organizational commitment can also be detected. By emphasizing a required ethical climate dimension for organizations this study therefore presents in outline a partial strategy to reduce bullying behaviour and to increase organizational commitment.

From past research it is well known that social exclusion has detrimental consequences for mental health. To deal with these adverse effects, socially excluded individuals frequently turn to other humans for emotional support. While chatbots can elicit social and emotional responses on the part of the human interlocutor, their effectiveness in the context of social exclusion has not been investigated. In the present study, we examined whether an empathic chatbot can serve as a buffer against the adverse effects of (...) social ostracism. After experiencing exclusion on social media, participants were randomly assigned to either talk with an empathetic chatbot about it (e.g., “I'm sorry that this happened to you”) or a control condition where their responses were merely acknowledged (e.g., “Thank you for your feedback”). Replicating previous research, results revealed that experiences of social exclusion dampened the mood of participants. Interacting with an empathetic chatbot, however, appeared to have a mitigating impact. In particular, participants in the chatbot intervention condition reported higher mood than those in the control condition. Theoretical, methodological, and practical implications, as well as directions for future research are discussed. (shrink)

BackgroundIn recent years, some researchers have engaged in scientific misconduct such as fabrication, falsification, and plagiarism to achieve higher research performance. Considering their detrimental effects on individuals’ health status (e.g., patients, etc.) and extensive financial costs levied upon healthcare systems, such wrongdoings have even more salience in medical sciences. However, there has been little discussion on the possible influence of medical researchers’ existing creative performance on scientific misconduct, and the moral psychological mechanisms underlying those effects are still poorly understood.MethodsWe (...) build a moderated mediation model to test how medical researchers’ creative performance affects their scientific misconduct and explore the role of moral licensing and moral identity in this process. Based on situational experiments and projection techniques, 287 medical researchers in China participated in a survey.ResultsMedical researchers’ creative performance positively relates to scientific misconduct, and moral licensing plays a mediating role in the relationship between them. In addition, moral identity has a negative moderating effect on the mediating effect of moral licensing on creative performance and scientific misconduct.ConclusionMoral licensing plays a fully mediating role in the relationship between creative performance and scientific misconduct. And moral identity negatively moderates the indirect effect of creative performance on scientific misconduct through moral licensing. The findings provide theoretical and practical implications for the prevention of medical researchers’ scientific misconduct. (shrink)

Despite society’s increasing sensitivity toward green production, companies often struggle to find effective communication strategies that induce consumers to buy green products or engage in other environmentally friendly behaviors. To add clarity to this situation, we investigated the effectiveness of negative versus positive message framing in promoting green products, whereby companies highlight the detrimental versus beneficial environmental consequences of choosing less versus more green options, respectively. Across four experiments, we show that negatively framed messages are more effective than positively (...) framed ones in prompting consumers to engage in pro-environmental behaviors. More importantly, we find that anticipated shame is the emotion responsible for this effect. Furthermore, both environmental concern and the type of product promoted serve as moderators; thus, the mediating role of anticipated shame is attenuated when environmental concern is low and the product is a luxury one. Finally, we discuss the theoretical and managerial implications of our work, along with its limitations and some directions for future research. (shrink)

It has been contended that ostracism is prevalent in the workplace, and there has been increasing research interest in its potential effects. This paper extends the theoretical framework of workplace ostracism by linking it with affective commitment and intention to leave from the perspective of job embeddedness. Using time-lagged data from China, we apply job embeddedness theory to confirm that workplace ostracism decreases the cultivation of job embeddedness, which in turn undermines affective commitment and induces intention to leave. We also (...) find that intrinsic work motivation strengthens the detrimental effects of workplace ostracism on job embeddedness such that the negative relationship is stronger when intrinsic motivation is high rather than low. We further discuss the theoretical and practical implications of our findings and offer future research directions. (shrink)

ABSTRACT Most university students have engaged in some form of academic dishonesty. These actions can have detrimental consequences for the student, the university, and society at large. It is important to understand factors that contribute to academic dishonesty as well as to identify potential predictors of this behavior. This study employed an experimental design with 361 undergraduate students in a laboratory setting. Deception was used during the experiment to determine the impact of peer influence, personality, and an honor code (...) on cheating behavior. Results revealed that peer influence had the largest impact on cheating behavior. In addition, personality, specifically, individuals who scored high on the openness trait were significantly more likely to cheat than those who scored lower on this trait. Implications of these findings for addressing academic dishonesty in higher education are provided. (shrink)

The Culpable Control Model assumes that causal judgments are irrational: a negative evaluative reaction to an agent would lead individuals to overestimate his causal contribution to a harm. However, the extent to which these judgments deviate from criteria of rationality remains unclear. The two present studies aimed at investigating conditions under which this effect occurs. Participants red a vignette in which the evaluative reaction was operationalized through the agent’s motives (blameworthy, laudable). We also varied the causal link between the (...) agent’s action and the outcome (strong, weak, preempted). In both studies, we found that negative motives influenced causal judgments when a strong action-outcome link could be established. In Study 2, we replicated the effect of motives on causal judgment in the weak link condition. However, participants consistently judged the agent as less causal when the link was weak (vs. strong), regardless of the agent’s motives. These findings show that both the presence and the strength of the actual causal link between the action and the outcome moderate the detrimental effect of negative evaluative reactions on causal judgments. Thus, common sense causal judgments seem to deviate relatively little from the criteria of rationality. (shrink)

Retrospective and prospective data collected in Cameroon were used to reassess hypotheses about how infant and early childhood mortality is affected by birth spacing and breast-feeding. These data show that: (a) a short preceding birth interval is detrimental for child survival in the first 4 months of life; (b) full and partial breast-feeding have direct protective effects on child survival in the first 4-6 months of life, with the effects of the former stronger than those of the latter; (c) (...) early subsequent conception significantly increases mortality risks in the first 16 months of life of the index child. These findings are robust to various controls, e.g. study design, data defects, child's health conditions at/around birth, postnatal maternal and child recurrent illnesses, patterns of utilisation of health care services, and immunisation status of the child.

History in this age needs to record and analyze the events in the light of modern concept of contemporary world. When the historians narrate the brutal condition of Indo-Pak history, they never forget the work and services of Shaykh Ahmad Sirhindi to transform the society according to the current values. For his services, he is hailed as Mujaddid Alf-I-Thani. The Muslim society had degenerated when Mujaddid Alf-I-Thani appeared on the horizon. A number of Hindu customs and practices had become the (...) part of their creed. The commandments of Shariat and Sunnah were being floated. Moreover, the Mughal emperor Akbar had adopted controversial policies detrimental to the very existence of Muslim society. Mujaddid Alf -Thani made strenuous and constant efforts to turn the tide. When Mujadded-Alf-Thani started his social reform movement, he found that the Muslim society was embracing un-Islamic practices such as widespread belief in Karamat had developed under the influence of Hindu thinking. Moreover, the Islamic teachings had been vitiated by adopting customs and practices of other religions such as inter marriages between Hindus and Muslims and ban on cow slaughter etc. Shaykh Ahmad Sirhindi never entered into any political conflict directly. He endeavored to restore pure doctrine to Islamic thought and to compel the Muslims to follow Shariat and Sunnah in letter and spirit. He was a social reformer, great Alim, Sufi and Mujaddid. He initiated a process of social change, inspired by Islamic Ideal, in an age, which was becoming secular. This research paper is an attempt to mention the role of Shaykh Ahmad Sirhindi for saving the society from un-Islamic values and customs in the sub-continent and its impact on society. By utilizing the historical method, this paper aims at analyzing the effect of social reforms of Shaykh Ahmed Sirhindi on Muslim society. (shrink)

Journal of Human Values, Volume 28, Issue 2, Page 115-128, May 2022. Is emotional labour a burden or a boon to service providers who have greater workplace spirituality? We test a moderated mediation model in which emotional exhaustion mediates the conjoint effect of WS and emotional labour on job satisfaction. Linking conservation of resources theory with the mechanism of ‘value congruence’ in person–environment fit theory, we theorize that spiritual values are a key factor in generating necessary resource gains for (...) deep acting due to the value fit of these two motivational vectors. As a boundary condition for use of the benefits of DA, WS can bridge the gap between theoretical assumptions concerning the benefits of DA and the lack of empirical evidence that DA mitigates emotional exhaustion. Concurrently, we challenge the perception of WS as universally beneficial to employees’ wellbeing by proposing that WS amplifies the detrimental effects of surface acting because the externalized and inauthentic nature of this type of emotional regulation transgresses basic spiritual values. Our hypotheses find support in a study of 196 Israeli service providers at inbound call centres. (shrink)

Distractibility is one of the key features of attention deficit hyperactivity disorder and has been associated with alterations in the neural orienting and alerting networks. Task-irrelevant stimuli are thus expected to have detrimental effects on the performance of patients with ADHD. However, task-irrelevant presentation of novel sounds seems to have the opposite effect and improve subsequent attentional performance particularly in patients with ADHD. Here, we aimed to understand the neural modulations of the attention networks underlying these improvements. Fifty (...) boys participated in a functional magnetic resonance imaging study in which unique or repeatedly presented sounds were placed before a visual flanker task in 2/3 of the trials. We found that presenting any sound improved task performance in all participants, but the underlying neural mechanisms differed for the type of sound. Familiar sounds led to a stronger increase in activity in the left posterior insula in patients with ADHD compared to typically developing peers. Novel sounds led to activations of the fronto-temporoparietal ventral attention network, likewise in ADHD and TD. These changes in signaling by novelty in the right inferior frontal gyrus were directly related to improved response speed showing that neural orienting network activity following novel sounds facilitated subsequent attentional performance. This mechanism of behavioral enhancement by short distractions could potentially be useful for cognitive trainings or homework situations. (shrink)

Many parents worry over their children’s gaming habits, but to what extent do such worries match any detrimental effects of excessive gaming? We attempted to answer this question by comparing children of highly concerned parents with other adolescents of the same age. A cohort of parents who identified as highly concerned over their children’s video game habits were recruited for a public study in collaboration with a national television network. Using an online experimental platform in conjunction with surveys of (...) parents’ beliefs and attitudes, we compared their children to age-matched peers in an exploratory case-control study. The scores of children with highly concerned parents on tests of cognitive control and psychological wellbeing were statistically similar to controls, suggesting no selective cognitive or psychological detriments from gaming or otherwise in the cases with concerned parents. The case group, however, did spend more time gaming, and scored higher than controls on problem gaming indicators, which also correlated negatively with wellbeing. Within the case group, wellbeing effects seemed mainly to consist in issues of relaxation and sleep, and related to gaming addiction indicators of playing to forget real-world problems, and the feeling of neglecting non-gaming activities. Where most results of research staged for TV never get published, making it difficult to interpret both methods and results, this paper describes findings and participant recruitment in detail. The relationship between parental concern and children’s gaming is discussed, as is the merits and challenges of research conducted with media, such as TV programs and their recruited on-screen participants.

Multiple studies revealed detrimental effects of face masks on communication, including reduced empathic accuracy and enhanced listening effort. Yet, extant research relied on artificial, decontextualised stimuli, which prevented assessing empathy under more ecologically valid conditions. In this preregistered online experiment (N = 272), we used film clips featuring targets reporting autobiographical events to address motivational mechanisms underlying face mask effects on cognitive (empathic accuracy) and emotional facets (emotional congruence, sympathy) of empathy. Surprisingly, targets whose faces were covered by a (...) mask (or a black bar) elicited the same level of empathy motives (affiliation, cognitive effort), and accordingly, the same level of cognitive and emotional empathy compared to targets with uncovered faces. We only found a negative direct effect of face coverings on sympathy. Additional analyses revealed that older (compared to young) adults showed higher empathy, but age did not moderate face mask effects. Our findings speak against strong negative face mask effects on empathy when using dynamic, context-rich stimuli, yet support motivational mechanisms of empathy. (shrink)

The persistent pervasiveness of inappropriately small studies in empirical fields is regu-larly deplored in scientific discussions. Consensually, taken individually, higher-powered studies are more likely to be truth-conducive. However, are they also beneficial for the wider performance of truth-seeking communities? We study the impact of sample sizes on collective exploration dynamics under ordinary conditions of resource limita-tion. We find that large collaborative studies, because they decrease diversity, can have detrimental effects in certain realistic circumstances that we characterize precisely. We show (...) how limited inertia mechanisms may partially solve this pooling dilemma and dis-cuss our findings briefly in terms of editorial policies. (shrink)

Previous research has shed light on the detrimental effects of abusive supervision. To extend this area of research, we draw upon conservation of resources theory to propose a causal relationship between abusive supervision and psychological distress, a mediating role of psychological distress on the relationship between abusive supervision and employee silence, and a moderating effect of the supervisor–subordinate relational context on the mediating effect of abusive supervision on silence. Through an experimental study, we found the causal path (...) linking abusive supervision and psychological distress. Results of both the experimental study and a field study provided evidence that psychological distress mediated the relationship between abusive supervision and silence. Lastly, we found support that this mediation effect was contingent upon the relational context in Study 2 but not in Study 1. We discuss implications for theory and practice. (shrink)

This study aims to provide a comprehensive understanding about the mechanism that underlies the detrimental effects of workplace spirituality dimensions on employee unethical pro-organizational behavior, directly as well as indirectly, through job satisfaction. Using a sample consisting of 458 employees in various organizations in China, this study reveals that two dimensions of WPS are positively associated with UPB. Also the results of this paper show that each of the three dimensions of WPS has a significant positive relationship with job (...) satisfaction. Furthermore, this study successfully confirms the mediating effect of job satisfaction in the relationship between WPS dimensions and UPB. Finally, theoretical and practical implications, future research directions and limitations of this study are discussed at the end of this research article. (shrink)

There is growing worldwide concern that the rampant spread of digital fake news via new media technologies is detrimentally impacting Democratic elections. However, the actual influence of this recent Internet phenomenon on electoral decisions has not been directly examined. Accordingly, this study tested the effects of attention to DFN on readers’ Presidential candidate preferences via an experimental web-survey administered to a cross-sectional American sample. Results showed no main effect of exposure to DFN on participants’ candidate evaluations or vote choice. (...) However, the perceived believability of DFN about the Democratic candidate negatively mediated evaluations of that candidate—especially amongst far-right ideologues. These results suggest that DFN may at worst reinforce the partisan dispositions of mostly politically conservative Internet users, but does not cause or induce conversions in these dispositions. Overall, this study contributes novel experimental evidence, indicating that the potential electoral impact of DFN, although concerning, is strongly conditional on a reciprocal interaction between message receptibility and a pre-existing right-wing ideological orientation. The said impact is, therefore, likely narrow in scope. (shrink)

Sleep strengthens memories by repeatedly reactivating associated neuron ensembles. Our studies show that although long-term memory for a medium number of word-pairs benefits from sleep, a large number does not. This suggests an upper limit to the amount of information that has access to sleep-dependent declarative memory consolidation, which is possibly linked to the availability of reactivation opportunities. Due to competing processes of global forgetting that are active during sleep, we hypothesized that even larger amounts of information would enhance the (...) proportion of information that is actively forgotten during sleep. In the present study, we aimed to induce such forgetting by challenging the sleeping brain with vast amounts of to be remembered information. For this, 78 participants learned a very large number of 640 word-pairs interspersed with periods of quiet awake rest over the course of an entire day and then either slept or stayed awake during the night. Recall was tested after another night of regular sleep. Results revealed comparable retention rates between the sleep and wake groups. Although this null-effect can be reconciled with the concept of limited capacities available for sleep-dependent consolidation, it contradicts our hypothesis that sleep would increase forgetting compared to the wake group. Additional exploratory analyses relying on equivalence testing and Bayesian statistics reveal that there is evidence against sleep having a detrimental effect on the retention of declarative memory at high information loads. We argue that forgetting occurs in both wake and sleep states through different mechanisms, i.e., through increased interference and through global synaptic downscaling, respectively. Both of these processes might scale similarly with information load. (shrink)

Workplace bullying is a phenomenon that can have serious detrimental effects on health, work-related attitudes, and the behavior of the target. Particularly, workplace bullying exposure has been linked to lower level of general well-being, job satisfaction, vigor, and performance and higher level of burnout, workplace deviance, and turnover intentions. However, the psychological mechanisms behind these relations are still not well-understood. Drawing on psychological contract and self-determination theory (SDT), we hypothesized that perceptions of contract violation and the frustration of basic (...) needs mediate the relationship between workplace bullying exposure and well-being, attitudinal, and behavioral outcomes. Self-reported data were collected among employees with different working backgrounds (N= 1,257)viaAmazon's Mechanical Turk in an online survey. Results showed that feelings of contract violation and frustration of basic needs accounted for unique variation in well-being, work satisfaction, burnout, vigor, and turnover intentions, pointing to individual contributions of both psychological mechanisms. However, when controlled for frustration of basic needs, feelings of psychological contract violation were no longer a mediator between workplace bullying exposure and work performance. Helping employees to deal effectively with workplace bullying exposure might buffer its negative effects and reduce their experienced frustration of basic needs, preserving their well-being, vigor, and work performance and, eventually, prevent burnout. The present study is the first to concurrently elucidate the proposed psychological mechanisms and unique contributions of psychological contract violation and frustration of basic needs in the context of workplace bullying.

According to Hume, experience in observing art is one of the prerequisites for being an ideal art critic. But although Hume extols the value of observing art for the art critic, he says little about the value, for the art critic, of executing art. That is, he does not discuss whether ideal aesthetic judges should have practiced creating the form of art they are judging. In this paper, I address this issue. Contrary to some contemporary philosophers who claim that experience (...) in creating art is irrelevant to one’s ability to judge that art form, as well as to some dance critics who see dance training as possibly even detrimental to one’s aesthetic judgment, I suggest that having practiced dancing makes one a better observer of certain aesthetic qualities of dance. Dance training, I argue, can facilitate a kinesthetic experience upon watching dance without which some aesthetic aspects of a dance performance—such as grace, power, and precision, as perceived kinesthetically—may go unnoticed.

Central sensitization refers to the increased responsiveness of nociceptive neurons in the central nervous system after repeated or sustained peripheral nociceptor activation. It is hypothesized to play a key role in the development of chronic pain. A hallmark of central sensitization is an increased sensitivity to noxious mechanical stimuli extending beyond the injured location, known as secondary hyperalgesia. For its ability to modulate the transmission and the processing of nociceptive inputs, attention could constitute a promising target to prevent central sensitization (...) and the development of chronic pain. It was recently shown that the experimental induction of central sensitization at both forearms of healthy volunteers using bilateral high-frequency electrocutaneous stimulation (HFS), can be modulated by encouraging participants to selectively focus their attention to one arm, to the detriment of the other arm, resulting in a greater secondary hyperalgesia on the attended arm as compared to the unattended one. Given the potential value of the question being addressed, we conducted a preregistered replication study in a well-powered independent sample to assess the robustness of the effect, i.e., the modulatory role of spatial attention on the induction of central sensitization. This hypothesis was tested using a double-blind, within-subject design. Sixty-seven healthy volunteers performed a task that required focusing attention toward one forearm to discriminate innocuous vibrotactile stimuli while HFS was applied on both forearms simultaneously. Our results showed a significant increase in mechanical sensitivity directly and 20 min after HFS. However, in contrast to the previous study, we did not find a significant difference in the development of secondary hyperalgesia between the attended vs. unattended arms. Our results question whether spatial selective attention affects the development of secondary hyperalgesia. Alternatively, the non-replication could be because the bottom-up capture of attention caused by the HFS-mediated sensation was too strong in comparison to the top-down modulation exerted by the attentional task. In other words, the task was not engaging enough and the HFS pulses, including those on the unattended arm, were too salient to allow a selective focus on one arm and modulate nociceptive processing.

While living a life based on universal principles is well accepted by many, the reality of living acts as a great detriment to those who want to centre their lives on these timeless truths. Further, institutional mechanisms and work environments do not conform in general to such principle-centred living. The agents of the state, especially those in the police, have to work under tremendous obstacles and pressures from within and without, and often get a bad reputation, sometimes undeservingly. Moreover their (...) value systems may also degrade in these environments, a direction that requires to be altered by the ‘guardians of the law’. It is important to bring about alignment of values and ethical perceptions of state administrators with some universal laws. The Buddhist practice of vipassana mediation can play a significant role in such transformations, as is evident from the responses from Delhi Police personnel who underwent vipassana in one of their training programmes. Vipassana has made significant differences in the lives and perceptions of these trainees—both at the professional and personal level. This paper introduces these concepts and cites evidences from the feedback sheets of trainees to recommend worldwide adoption of such practices for those who occupy seats of power and responsibility. The feedback shows positive and very encouraging trends in all dimensions—work related, humanitarian, family and self—in other words, in professional, personal and deep inner lives. (shrink)

Associative memory is the ability to link together components of stimuli. Previous evidence suggests that prior familiarization with study items affects the nature of the association between stimuli. More specifically, novel stimuli are learned in a more context-dependent fashion than stimuli that have been encountered previously without the current context. In the current study, we first acquired behavioral data from 62 human participants to conceptually replicate this effect. Participants were instructed to memorize multiple object-scene pairs and were then tested (...) on their recognition memory for the objects. Importantly, 1 day prior, participants had been familiarized with half of the object stimuli. During the test phase, the objects were either matched to the same scene as during study or swapped with a different object’s scene. Our results conceptually replicated the context-dependency effect by showing that breaking up a studied object-context pairing is more detrimental to object recognition performance for non-familiarized objects than for familiarized objects. Second, we used functional magnetic resonance imaging to determine whether medial temporal lobe encoding-related activity patterns are reflective of this familiarity-related context effect. Data acquired from 25 human participants indicated a larger effect of familiarization on encoding-related hippocampal activity for objects presented within a scene context compared to objects presented alone. Our results showed that both retrieval-related accuracy patterns and hippocampal activation patterns were in line with a familiarization-mediated context-dependency effect. (shrink)

Mental fatigue can be studied by using either the time-on-task protocol or the sequential task protocol. In the time-on-task protocol, participants perform a long and effortful task and a decrease in performance in this task is generally observed over time. In the sequential task protocol, a first effortful or control task is followed by a second effortful task. The performance in the second task is generally worse after the effortful task than after the control task. The principal aim of the (...) present experiment is to examine the relationship between these two decrements in performance while concomitantly using a sequential task protocol and assessing the performance of the first effortful task as a function of time-on-task. We expect a positive correlation between these two decrements in performance. A total of 83 participants performed a 30-min fatiguing mental task or a control task followed by a time-to-exhaustion handgrip task. As expected, this protocol combining the time-on-task and sequential task protocols allowed us to observe a decrease in performance over time during the Stroop task, a worst performance in the handgrip task after the Stroop task by comparison to the control task, a positive correlation between these two effects. The decrease in performance during the Stroop task also correlated with the subjective measures of boredom and fatigue, whereas the detrimental effect observed in the handgrip task did not. Our findings suggest that the two fatigue-related phenomena share a common mechanism but are not completely equivalent. (shrink)
