How does reflective thinking impact decisions about ethics, mind, politics, or other philosophical domains? Reflective reasoning often correlates with better decision-making performance and certain philosophical preferences (e.g., utilitarian moral decisions). However, experiments suggest that reflection is not always the cause of these outcomes. Further, some evidence casts doubt on the trustworthiness of data from certain online crowd work platforms such as Amazon Mechanical Turk (mTurk). This paper reports results of a pre-registered experiment on participants from multiple sources (mTurk, (...) CloudResearch, Prolific, and a university). The experiment investigated how reflective thinking relates to judgments about philosophical thought experiments (concerning knowledge, morality, personal identity, and more). First- and third-party data quality measures found up to 18 times as much low-quality data from mTurk as other sources. Analyzing across participant sources, some prior correlations between reflection and certain philosophical tendencies replicated (e.g., denying that accidentally true beliefs count as knowledge). However, a common reflection test prime failed to find evidence that reflection caused the corresponding philosophical preferences. Rather, a philosophical priming effect emerged: thinking through philosophical vignettes before taking a reflection test improved test performance—but only among those that passed the data quality checks. Together, these data suggest that the direction of causation between reflective and philosophical thinking may be the opposite of what dual process theories have suggested, and that researchers’ ability to detect such relationships can depend on participant source and data quality.

Recent research in empirical moral psychology attempts to understand (rather than place judgment on) the salient normative differences that laypeople have when making moral decisions by using survey methodology that is based on the operationalized principles from moral theories. The PPIMT is the first measure designed to assess respondents’ preference for the precepts implied in the three dominant moral theories: virtue ethics, deontology, and consequentialism. The current study used a latent modeling approach to determine the most theoretically and psychometrically-sound model (...) for the PPIMT using a combined sample of college students from a southeastern university in U.S. and MTurk respondents. The PPIMT model fit was acceptable (χ2 = 84.125, df = 40, p = 0.001; RMSEA = 0.052, 90%CI = 0.037 to 0.068; CFI = 0.980; SRMR = 0.035) with four items for Virtue, four items for Deontology, and three items for Consequentialism.

Motivated reasoning occurs when we reason differently about evidence that supports our prior beliefs than when it contradicts those beliefs. Adult participants (N = 377) from Amazon’s Mechanical Turk (MTurk) system completed written responses critically evaluating strengths and weaknesses in a vignette on the topic of anthropogenic climate change (ACC). The vignette had two fictional scientists present prototypical arguments for and against anthropogenic climate change that were constructed with equally flawed and conflicting reasoning. The current study tested and found (...) support for three main hypotheses: cognitive style, personality, and ideology would predict both motivated reasoning and endorsement of human caused climate change; those who accept human-caused climate change will be less likely to engage in biased reasoning and more likely to engage in objective reasoning about climate change than those who deny human activity as a cause of climate change.

Crowdsourcing is an increasingly popular method for researchers in the social and behavioral sciences, including experimental philosophy, to recruit survey respondents. Crowdsourcing platforms, such as Amazon’s Mechanical Turk (MTurk), have been seen as a way to produce high quality survey data both quickly and cheaply. However, in the last few years, a number of authors have claimed that the low pay rates on MTurk are morally unacceptable. In this paper, I explore some of the methodological implications for online (...) experimental philosophy research if, in fact, typical pay practices on MTurk are morally impermissible. I argue that the most straightforward solution to this apparent moral problem—paying survey respondents more and relying only on “high reputation” respondents—will likely increase the number of subjects who have previous experience with survey materials and thus are “non-naïve” with respect to those materials. I then discuss some likely effects that this increase in experimental non-naivete will have on some aspects of the “negative” program in experimental philosophy, focusing in particular on recent debates about philosophical expertise.

In two studies, we tested how the expression of civic hope in narratives and the perceived authenticity of civic/political actions relate to civic/political engagement. In a cross-sectional study of undergraduates (N = 230), the expression of civic hope predicted the perceived authenticity of civic actions (e.g., voting), which in turn predicted the motivation to engage in them. In a longitudinal on-line study that began 8 weeks prior to the 2020 U.S. Presidential election (N = 308 MTurk workers), overall expressions (...) of civic hope positively predicted the perceived authenticity of voting and the motivation to vote. In addition, expressions of civic hope positively predicted the perceived authenticity of voting, which in turn positively predicted the likelihood of reporting that one did vote. These findings indicate that a sense of civic hope and the experience of authenticity in political contexts may be important for democratic engagement. (shrink)

The present study evaluated the relationship between job satisfaction and unethical pro-organizational behavior (UPB), directly as well as indirectly, through organizational commitment. Multidimensional constructs were utilized for job satisfaction and organizational commitment to provide a granular understanding of how these constructs can motivate employees to engage in UPB, which can threaten organizations' success and diminish the public's confidence in organizations. In order to test these relationships, a diverse sample of 617 participants was recruited through the online survey distribution platform Amazon (...) Mechanical Turk (MTurk®) to test the theoretical model using structural equation modeling (SEM). The results indicated that identification, affiliation, and exchange commitment served as intervening variables between growth satisfaction and UPB, while no significant indirect effect of internal work motivation on UPB was found. Implications for research and practice are discussed. (shrink)

Mentioning products or brands on Facebook enables individuals to display an ideal self to others through a form of virtual conspicuous consumption. Drawing on conspicuous donation behaviour literature, we investigate ‘conspicuous virtue signalling’, as conspicuous consumption on Facebook. CVS occurs when an individual mentions a charity on their Facebook profile. We investigate need for uniqueness and attention to social comparison information as antecedents of two types of CVS–self-oriented and other-oriented. We also explore the relationship between CVS and self-esteem, and offline (...) prosocial and unethical behaviour intentions. Data from two studies, a college survey and an adult survey via MTurk, were analysed using structural equation modelling. Results indicate that NFU predicts both forms of CVS, while ATSCI influences both forms of CVS for adults and other-oriented CVS for students. Self-esteem is enhanced by self-oriented CVS. Self-oriented CVS predicts donation intention whereas other-oriented CVS significantly reduces donation intention for both samples. Furthermore, a significant relationship between CVS and purchase intention of counterfeit luxury goods is revealed. Findings provide insights into conspicuous virtue signalling and the relationship between CVS on Facebook and offline behavioural intentions. (shrink)

Research ethics committees and institutional review boards spend considerable time developing, scrutinising, and revising specific consent processes and materials for survey-based studies conducted on crowdsourcing and online recruitment platforms such as MTurk and Prolific. However, there is evidence to suggest that many users of ICT services do not read the information provided as part of the consent process and they habitually provide or refuse their consent without adequate reflection. In principle, these practices call into question the validity of their (...) consent. In this paper we argue that although the ‘no read problem’ and the routinisation of consent may apply to research participants’ consent practices for studies on crowdsourcing platforms, this is not a serious problem. Furthermore, given that the informational requirements for informed consent in these contexts are minimal, we argue that these participants are, nevertheless, sufficiently informed to give valid consent. We conclude that research ethics committees and institutional review boards should only agonise over the precise details of the informed consent process and materials in those rare cases where appreciable risks to research participants need to be managed.

In the WebSurf task, humans forage for videos paying costs in terms of wait times on a time-limited task. A variant of the task in which demands during the wait time were manipulated revealed the role of attention in susceptibility to sunk costs. Consistent with parallel tasks in rodents, previous studies have found that humans preferred shorter delays, but waited longer for more preferred videos, suggesting that they were treating the delays economically. In an Amazon Mechanical Turk sample, we replicated (...) these predicted economic behaviors for a majority of participants. In the lab, participants showed susceptibility to sunk costs in this task, basing their decisions in part on time they have already waited, which we also observed in the subset of the mTurk sample that behaved economically. In another version of the task, we added an attention check to the wait phase of the delay. While that attention check further increased the proportion of subjects with predicted economic behaviors, it also removed the susceptibility to sunk costs. These findings have important implications for understanding how cognitive processes, such as the deployment of attention, are key to driving re-evaluation and susceptibility to sunk costs. (shrink)

Fraud is a pervasive and challenging problem that costs society large amounts of money. By no means all fraud is committed by ‘professional criminals’: much is done by ordinary people who indulge in small-scale opportunistic deception. In this paper, we set out to investigate when people behave dishonestly, for example by committing fraud, in an online context. We conducted three studies to investigate how the rejection of one’s efforts, operationalized in different ways, affected the amount of cheating and information falsification. (...) Study 1 demonstrated that people behave more dishonestly when rejected. Studies 2 and 3 were conducted in order to disentangle the confounding factors of the nature of the rejection and the financial rewards that are usually associated with dishonest behavior. It was demonstrated that rejection in general, rather than the nature of a rejection, caused people to behave more dishonestly. When a rejection was based on subjective grounds, dishonest behavior increased with approximately 10%, but this difference was not statistically significant. We subsequently measured whether dishonesty was driven by the financial loss associated with rejection, or emotional factors such as a desire for revenge. We found that rejected participants were just as dishonest when their cheating did not led to financial gain. However, they felt stronger emotions when there was no money involved. This seems to suggest that upon rejection, emotional involvement, especially a reduction in happiness, drives dishonest behavior more strongly than a rational cost-benefit analysis. These results indicate that rejection causes people to behave more dishonestly, specifically in online settings. Firms wishing to deter customers and employees from committing fraud may therefore benefit from transparency and clear policy guidelines, discouraging people to submit claims that are likely to be rejected.

The inconsistency between pro-environmental attitudes and behaviours, known as the “attitude-behaviour” gap, is exceptionally pronounced in scenarios associated with “green” choice. The current literature offers numerous explanations for the reasons behind the “attitude-behaviour” gap, however, the generalisability of these explanations is complex. In addition, the answer to the question of whether the gap occurs between attitudes and intentions, or intentions and behaviours is also unknown. In this study, we propose the moral dimension as a generalisable driver of the “attitude-behaviour” gap (...) and investigate its effectiveness in predicting attitudes, pro-environmental intentions and subsequent behaviours. We do so by using Hunt–Vitell’s moral philosophy-based framework of ethical decision-making, which conceptualises morality as the central decision-making parameter. The results from 557 US MTurk participants revealed that the manipulation of moral dimensions, specifically deontology and teleology, impacted ethical evaluation of presented dilemmas, however, failed to translate into subsequent intentions and behaviours. This finding suggests (i) that the moral dimension has an effect in shaping attitudes toward environmental issues, and (ii) that gap occurs between attitudes and intentions rather than intentions and behaviours. Further investigation of what strengthens and/or overrides the effects of the moral dimension would help understand the reasons why moral attitudes do not always translate into subsequent intentions and behaviours in the pro-environmental domain.

Many individuals have experienced a multitude of chronic stressors and diminished psychological functioning during COVID-19. The current study examined whether biases towards positive social media or positive autobiographical memories was related to increases in psychological functioning during COVID-19. Participants were 1071 adults (Mage = 46.31; 58% female; 78% White) recruited from MTurk. Participants reported on their social media consumption and autobiographical recall, positive and negative affect, and dysphoria symptoms. Results indicated that, at the first assessment collected in the spring (...) and summer of 2020, positively biased social media consumption was cross-sectionally related to higher levels of positive affect, and positively biased autobiographical recall was cross-sectionally related to lower levels of negative affect and dysphoria symptoms. Sensitivity analyses examined cross-sectional relations from a second assessment collected in fall 2020, and prospective cross-lagged analyses. The findings point to potential psychological benefits of positive biases during chronic stressors. (shrink)

Under resource dependence theory, firms should benefit from diverse boards of directors. Ethical arguments also highlight that boards should be as diverse as the stakeholders and communities that they serve. In an attempt to increase diversity and women’s presence on boards of directors, legislative efforts have enacted gender quotas. We examine how such efforts are perceived by U.S. market participants. We expect that when a firm operating under a quota law meets only the minimum requirement, investors will view the female (...) directors through the lens of token status theory and invest fewer resources in that firm than they will in a firm that exceeds the quota minimum or has the same composition but is not under a quota law. Through an experiment with 207 MTurk participants, we manipulated whether a firm was or was not under a quota law and whether the number of female board members was just at or exceeded the law’s minimum compliance. We find evidence that under a quota system, U.S. market participants tend to view female directors as tokens when the firm is just at the quota minimum, and these perceptions both affect their view of the firm’s prospects and negatively influence investment decisions. Importantly, however, we find that these negative effects can be offset and that resource dependence theory holds if the firm _exceeds_ the quota, signaling that the hiring of female directors is not simply compliance-dependent and subsequently leading U.S. market participants to invest more resources in the firm.

ObjectiveIn this study, we extend the impact of mindfulness to the concept of least-worst decision-making. Least-worst decisions involve high-uncertainty and require the individual to choose between a number of potentially negative courses of action. Research is increasingly exploring least-worst decisions, and real-world events (such as the COVID-19 pandemic) show the need for individuals to overcome uncertainty and commit to a least-worst course of action. From sports to business, researchers are increasingly showing that “being mindful” has a range of positive performance-related (...) benefits. We hypothesized that mindfulness would improve least-worst decision-making because it would increase self-reflection and value identification. However, we also hypothesized that trait maximization (the tendency to attempt to choose the “best” course of action) would negatively interact with mindfulness.MethodsThree hundred and ninety-eight participants were recruited using Amazon MTurk and exposed to a brief mindfulness intervention or a control intervention (listening to an audiobook). After this intervention, participants completed the Least-Worst Uncertain Choice Inventory for Emergency Responders (LUCIFER).ResultsAs hypothesized, mindfulness increased decision-making speed and approach-tendencies. Conversely, for high-maximizers, increased mindfulness caused a slowing of the decision-making process and led to more avoidant choices.ConclusionsThis study shows the potential positive and negative consequences of mindfulness for least-worst decision-making, emphasizing the critical importance of individual differences when considering both the effect of mindfulness and interventions aimed at improving decision-making.

Maximizing is a topic that has received significant attention from researchers and corporate organizations alike. Although extensive previous research has explored how maximizers behave in a decision scenario, a fundamental question remains about why they prefer a larger assortment regardless of whether the decisions are important or not. This study attempts to explore the underlying mechanism of this phenomenon. Four surveys were conducted, and participants from Mturk or Credamo online platforms were recruited. The maximizing tendency was measured by either (...) maximization scale or maximizing tendency scale, and perceived importance and preference for a large assortment were measured in different decision scenarios. Across four studies, we find that maximizers perceive the same decision as more important than satisficers, and perceived importance serves as the mechanism underlying the maximizers’ preference for a large assortment. In other words, in maximizers’ perceptions and interpretations, even seemingly trivial decisions are important enough to spend great effort on a large assortment. We additionally identified a boundary condition for the effect – cost salience. These findings illustrate a pioneering empirical exploration of the difference in the way maximizers and satisficers perceive their decision importance and the reason for maximizers’ preference for a large assortment.

Life history theory is a fruitful source of testable hypotheses about human individual differences. However, this field of study is beset by unresolved debates about basic concepts and methods. One of these controversies concerns the usefulness of instruments that purport to tap a unidimensional life history factor based on a set of self-reported personality, social, and attitudinal variables. Here, we take a novel approach to analyzing the psychometrics of two variants of the Arizona Life History Battery: the Mini-K and the (...) K-SF-42. Psychological network analysis generates models in which psychological variables comprise the nodes of a network, while partial correlation coefficients between these variables comprise the edges of the network. Centrality indices operationalize each node’s importance based on the pattern of the connections in which that node plays a role. Because childhood environments are hypothesized to influence adult LH, we tested the hypothesis that among the Mini-K items, and the K-SF-42 scales, those that tap relationships with parents are central to the networks constructed from these instruments. In an MTurk sample and an undergraduate sample that completed the Mini-K, and an MTurk sample that completed the K-SF-42, this hypothesis was falsified. Indeed, the “relationships with parents” items were among the most peripheral in all three networks. We propose that network analysis, as an alternative to latent variable modeling, offers considerable potential to test hypotheses about the input-output mappings of specific evolved psychological mechanisms.

The complex relationship between the current advancement of technology, including the wide scope of settings at which machinery plays substantial roles, and the cultural, historical, and political realities that have long existed across the history of mankind, is one that deserves absolute attention and exploration. This interconnection has been investigated in light of bread, and the meaning it signifies to people from all over the world. Drawing on the commonly unnoticed value of bread, and the everlasting impregnable imprint it has (...) always had on revolutions throughout history, “Collective Bread Diaries” came to being as an interactive art project, employing the artificial intelligence of the MTurk platform in its investigation of “bread” as one’s peculiar voice and political statement.

Chronic pain is associated with high levels of mental health issues and alterations in cognitive processing. Cognitive-behavioral models illustrate the role of memory alterations in the development and maintenance of chronic pain as well as in mental health disorders which frequently co-occur with chronic pain. This study aims to expand our understanding of specific cognitive mechanisms underlying chronic pain which may in turn shed light on cognitive processes underlying pain-related psychological distress. Individuals who reported a history of chronic pain and (...) individuals who reported no history of chronic pain were recruited from MTurk to complete an online survey including standardized measures of anxiety and depression and two sentence completion tasks that assessed autobiographical memory and future thinking specificity and content. Chi square analyses revealed that participants who endorsed experiencing chronic pain were significantly more likely to recall at least one painful and negative event and to imagine at least one anticipated painful event in their future. Two ANCOVAs were performed to examine the degree to which chronic pain endorsement influenced specificity in memory and future imagining. Individuals with a history of chronic pain and higher levels of depression symptom severity generated autobiographical memories with significantly less specificity; whereas, individuals with a history of chronic pain also generated future autobiographical events with significantly less specificity. In addition, individuals with a history of chronic pain were more likely to generate episodes related to pain when asked to recall the past or imagine the future. Further research is needed to improve our understanding of the etiology of autobiographical memory and future thinking specificity and content in the pathogenesis of mental health conditions in the context of chronic pain.

In this paper we evaluate how to effectively use the crowdsourcing service, Amazon’s Mechanical Turk (MTurk), to content analyze textual data for use in psychological research. MTurk is a marketplace for discrete tasks completed by workers, typically for small amounts of money. MTurk has been used to aid psychological research in general, and content analysis in particular. In the current study, MTurk workers content analyzed personally-written textual data using coding categories previously developed and validated in psychological (...) research. These codes were evaluated for reliability, accuracy, completion time, and cost. Results indicate that MTurk workers categorized textual data with comparable reliability and accuracy to both previously published studies and expert raters. Further, the coding tasks were performed quickly and cheaply. These data suggest that crowdsourced content analysis can help advance psychological research. (shrink)

Studies have shown that during social interaction a shared system underlies inferring one’s own mental state, and the mental states of others – processes often referred to as mentalization. However, no validated assessment has been developed to measure second order mentalization, or whether this capacity plays a significant role in social interaction. The current work presents a interactive mentalization theory, which divides these directional and second order aspects of mentalization, and investigates whether these constructs are measurable, stable, and meaningful in (...) social interactions. We developed a 20-item, self-report interactive mentalization questionnaire in order to assess the different sub-components of mentalization: self–self, self–other, and other–self mentalization. We then tested this scale on a large, online sample, and report convergent and discriminant validity in the form of correlations with other measures, as well as correlations with social deception behaviors in real online interaction with Mturk studies. These results validate the IMQ, and support the idea that these three factors can predict mentalization in social interaction. (shrink)

Background: Screen time among adults represents a continuing and growing problem in relation to health behaviors and health outcomes. However, no instrument currently exists in the literature that quantifies the use of modern screen-based devices. The primary purpose of this study was to develop and assess the reliability of a new screen time questionnaire, an instrument designed to quantify use of multiple popular screen-based devices among the US population. -/- Methods: An 18-item screen-time questionnaire was created to quantify use of (...) commonly used screen devices (e.g. television, smartphone, tablet) across different time points during the week (e.g. weekday, weeknight, weekend). Test-retest reliability was assessed through intra-class correlation coefficients (ICCs) and standard error of measurement (SEM). The questionnaire was delivered online using Qualtrics and administered through Amazon Mechanical Turk (MTurk). -/- Results: Eighty MTurk workers completed full study participation and were included in the final analyses. All items in the screen time questionnaire showed fair to excellent relative reliability (ICCs = 0.50–0.90; all < 0.000), except for the item inquiring about the use of smartphone during an average weekend day (ICC = 0.16, p = 0.069). The SEM values were large for all screen types across the different periods under study. -/- Conclusions: Results from this study suggest this self-administered questionnaire may be used to successfully classify individuals into different categories of screen time use (e.g. high vs. low); however, it is likely that objective measures are needed to increase precision of screen time assessment.

Providing valid responses to a self-report survey requires cognitive effort. Subjects engaging in insufficient effort responding (IER) are unwilling to take this effort. Compared to psychologists, experimental philosophers so far seem to have paid less attention to IER. This paper is an attempt to begin to alleviate this shortcoming. First, I explain IER’s nature, prevalence and negative effects in self-report surveys in general. Second, I argue that IER might also affect experimental philosophy studies. Third, I develop recommendations as to how (...) experimental philosophers should (and should not) try to prevent IER. Fourth, I develop recommendations as to how experimental philosophers should (and should not) try to detect IER.

BackgroundThe use of electronic nicotine delivery systems, also known as vaping, is becoming popular among young adults. Few studies have explored the psychological factors that predict ENDS use and susceptibility in young adults, in addition to known demographic predictors.MethodIn a cross-sectional survey design, 521 young adults, ages 18–25 from the United States, were recruited via Amazon’s Mechanical Turk in 2019, to answer an online survey measuring demographic characteristics and psychological characteristics related to mental health and the Big Five personality traits. (...) The survey also included measures of ENDS ever-use, current use, and susceptibility, which we predicted from the demographic and psychological measures using independent and multiple binary logistic regression analyses.ResultsOf those surveyed, 282 were ENDS ever-users, 93 were current ENDS users, and 61 were ENDS susceptible; 62 were current smokers. Demographically, young adults lower in adulthood socioeconomic-status, not pursuing education further than high school, and current smokers were more likely to be ENDS users. Psychologically, young adults higher in anxiety and lower in conscientiousness more likely to have ever-used ENDS. Lower conscientiousness further predicted current ENDS use and ENDS susceptibility.ConclusionIn this sample of MTurk workers, young adults with experience in vaping were more demographically and psychologically vulnerable than young adults with no experience in vaping. Young adults interested in vaping, but without prior experience, were less conscientious than their non-interested peers. Interventions to target vaping use should focus on economically disadvantaged young adults and those lower in conscientiousness. (shrink)

This study investigates: the changes in three major health-related factors—physical activity, non-physical-activity health behavior, and depressive symptoms, and how changes in physical activity were associated with changes in one’s depressive symptoms among young adults, middle-aged adults, and older adults while controlling non-physical-activity health behavior and sociodemographic characteristics among young, middle-aged, and older adults before and after the COVID-19 outbreak lockdown in the United States. A total of 695 participants completed an online questionnaire via MTurk, and participants were asked to (...) recall their physical activity, depressive symptoms, and non-physical-activity health behavior status in January and May of 2020. The IPAQ-SF was used to evaluate individuals’ physical activity, while the CES-D-10 was used to assess depressive symptoms. Covariates included non-physical-activity health behavior and sociodemographic factors. A Bayesian significance testing of changes was used to examine significant changes in physical activity, non-physical-activity behavior, and depressive symptoms in each age group while Bayesian regression analysis was employed to examine how the changes in physical activity were associated with respondents’ depressive symptoms while controlling for individual NHB and sociodemographic characteristics. The results showed that the participants tended to maintain their physical activity levels after the lockdown despite significant increases in sitting time among young and older adults. Decreases in moderate physical activity frequency were associated with a higher level of depressive symptoms. Although young and middle-aged cohorts experienced fewer differences in depressive symptoms compared to their counterparts in the older group, we found no significant heterogeneity effects in the relationships of interest across all age groups. Considering different influences of physical activity on depressive symptoms depending on different levels of activity and ages, more randomized clinical trials with program-based intervention studies should be conducted with different physical activity programs for different age populations.

Little is known about how individuals with and without mood disorders perceive the inherent risks and helpfulness of participating in innovative psychiatric research, or about the factors that influence their willingness to participate. We conducted an online survey with 80 individuals (self-reported mood disorder [n = 25], self-reported good health [n = 55]) recruited via MTurk. We assessed respondents’ perceptions of risk and helpfulness in study vignettes associated with two innovative research projects (intravenous ketamine therapy and wearable devices), as (...) well as their willingness to participate in these projects. Respondents with and without mood disorders perceived risk similarly across projects. Respondents with no mood disorders viewed both projects as more helpful to society than to research volunteers, while respondents with mood disorders viewed the projects as equally helpful to volunteers and society. Individuals with mood disorders perceived ketamine research, and the two projects on average, as more helpful to research volunteers than did individuals without mood disorders. Our findings add to a limited empirical literature on the perspectives of volunteers in innovative psychiatric research. (shrink)

Background The purpose of this study was to examine whether extended use of a variety of screen-based devices, in addition to television, was associated with poor dietary habits and other health-related characteristics and behaviors among US adults. The recent phenomenon of binge-watching was also explored. -/- Methods A survey to assess screen time across multiple devices, dietary habits, sleep duration and quality, perceived stress, self-rated health, physical activity, and body mass index, was administered to a sample of US adults using (...) the Qualtrics platform and distributed via Amazon Mechanical Turk (MTurk). Participants were adults 18 years of age and older, English speakers, current US residents, and owners of a television and at least one other device with a screen. Three different screen time categories (heavy, moderate, and light) were created for total screen time, and separately for screen time by type of screen, based on distribution tertiles. Kruskal-Wallis tests were conducted to examine differences in dietary habits and health-related characteristics between screen time categories. -/- Results Aggregate screen time across all devices totaled 17.5 h per day for heavy users. Heavy users reported the least healthful dietary patterns and the poorest health-related characteristics – including self-rated health – compared to moderate and light users. Moreover, unique dietary habits emerged when examining dietary patterns by type of screen separately, such that heavy users of TV and smartphone displayed the least healthful dietary patterns compared to heavy users of TV-connected devices, laptop, and tablet. Binge-watching was also significantly associated with less healthy dietary patterns, including frequency of fast-food consumption as well as eating family meals in front of a television, and perceived stress. -/- Conclusions The present study found that poorer dietary choices, as well as other negative health-related impacts, occurred more often as the viewing time of a variety of different screen-based devices increased in a sample of US adults. Future research is needed to better understand what factors among different screen-based devices might affect health behaviors and in turn health-related outcomes. Research is also required to better understand how binge-watching behavior contributes impacts health-related behaviors and characteristics. (shrink)

Smoking consequences are seen disproportionately among low-SES smokers. We examine the self-regulatory strategy of mental contrasting with implementation intentions as a smoking reduction tool and whether its effectiveness depends on subjective-SES. This pre-registered online experiment comprised a pre-screening, baseline survey, and follow-up. Participants reported past-week smoking, subjective-SES, perceived stress, and were randomized to an active control or MCII condition. Data were collected via MTurk, during the U.S.’ initial wave of COVID-19. Participants were moderate-to-heavy smokers open to reducing or quitting. (...) The primary outcome was self-reported smoking reduction, computed as the difference between recent smoking at baseline and follow-up. The secondary outcome was cessation, operationalized as self-reported 7-day point-prevalence abstinence at follow-up. Among those low—but not high—in subjective-SES, MCII improved smoking reduction by an average of 1.09 fewer cigarettes smoked per day, though this effect was not conclusive. Similarly, quitting was descriptively more likely for those in the MCII than control condition, but the effect was non-significant. Per an exploratory analysis, we observed that stress significantly moderated the condition effect, such that MCII facilitated reduction among those experiencing high, but not low stress. Consistent with prior findings that MCII works best in vulnerable populations, MCII may be more effective for smoking reduction among high-stress than low-stress individuals. These findings contribute to growing research on income-related health disparities and smoking behavior change tools. (shrink)

Meaningful work is a key element of positive functioning of employees, but what makes work meaningful? Based on research on self-determination theory, basic psychological needs, and prosocial impact, we suggest that there are four psychological satisfactions that substantially influence work meaningfulness across cultures: autonomy (sense of volition), competence (sense of efficacy), relatedness (sense of caring relationships), and beneficence (sense of making a positive contribution). We test the relationships between these satisfactions and perceived meaningful work in Finland (n = 594, employees (...) of several organizations), India (n = 342, collected through Mturk), and the USA (n = 373, collected through Mturk). Regression analyses show that – except for competence in USA – all four satisfactions are significantly and independently associated with meaningful work. Moreover, structural equation modeling shows that they fully mediated the relationship between occupational position and work meaningfulness in India and in the USA. In sum, the results support the importance of these four satisfactions in explaining the psychological underpinnings of meaningful work. (shrink)
