The recent upsurge in “brain-training and perceptual-cognitive-training", proposing to improve isolated processes such as brain function, visual perception and decision-making, has created significant interest in elite sports practitioners, seeking to create an ‘edge’ for athletes. The claims of these related 'performance-enhancing industries' can be considered together as part of a process training approach proposing enhanced cognitive and perceptual skills and brain capacity, to support performance in everyday life activities, including sport. For example, the 'process-training industry' promotes the idea that playing (...) games not only makes you a better player, but also smarter, more alert, and a faster learner. In this position paper we critically evaluate the effectiveness of both types of process-training programmes in generalizing transfer to sport performance. These issues are addressed in three stages. First, we evaluate empirical evidence in support of perceptual-cognitive process training, and its application to enhancing sport performance. Second, we critically review putative modularised mechanisms underpinning this kind of training, addressing limitations and subsequent problems. Specifically, we consider merits of this highly specific form of training, which focuses on training of isolated processes such as cognitive processes (attention, memory, thinking) and visual perception processes, separately from performance behaviors and actions. We conclude that these approaches may, at best, may provide some 'general transfer' of underlying processes to specific sport environments, but lack 'specificity of transfer' to contextualize actual performance behaviors. A major weakness of process training methods is their focus on enhancing performance in body “modules” (e.g., eye, brain, memory, anticipatory sub-systems). What is lacking is evidence on how these isolated components are modified and subsequently interact with other process “modules”, which are considered to underlie sport performance. Finally, we propose how an ecological dynamics approach, aligned with an embodied framework of cognition undermines the rationale that modularised processes can enhance performance in competitive sport. An ecological dynamics perspective proposes that the body is a complex adaptive system, interacting with performance environments in a functionally integrated manner, emphasising that the inter-relation between motor processes, cognitive and perceptual functions and the constraints of a sport task is best understood at the performer-environment scale of analysis.

This study investigates the increased commercialization of African indigenous vegetables (AIV)—former subsistence crops such as African nightshade, cowpea leaves and amaranth species grown mainly by women—from a feminist economics perspective. The study aims to answer the following research question: How does AIV commercialization affect the gendered division of labor, women’s participation in agricultural labor, their decision-making power, and their access to resources? We analyze commercialization’s effects on gender relations in labor and decision-making power and also highlight women’s agency. Based on (...) a mixed method design and analyzing household-level panel data and qualitative focus groups from Kenya, we observe an economic empowerment of women that we relate to women’s individual and collective strategies as well as their retention of control over AIV selling and profits. Yet, while we see economic empowerment of women through commercialization—how they broaden their scope of action and are empowered by generating revenue—that does not contribute to a redistribution of labor or land rights, which are key for gender equality, instead it increases women’s labor burden.

Background: In modern healthcare, the role of solidarity, altruism and the natural response to moral challenges in life-threatening situations is still rather unexplored. The COVID-19 pandemic provided an opportunity to obtain a deeper understanding of nurses’ willingness to care for patients during crisis. Objective: To elucidate clinical expressions of ontological situational ethics through nurses’ willingness to work during a pandemic. Research design, participants and context: A qualitative study with an interpretive design was applied. Twenty nurses who worked in intensive care (...) unit at two Swedish hospitals during the first, second, and third waves of the COVID-19 pandemic were interviewed. The analysis was interpretative and applied a theoretical ethics perspective. Ethical considerations: The study was approved by the Swedish Ethical Review Authority and informed consent was obtained from all participants. Findings: From a philosophical perspective, the nurses expressed sovereign life expressions of mercy and compassion, which arose spontaneously in response to seeing vulnerable fellow humans. They referenced ‘‘the nurse inside me’’ and their choice of profession as motives to provide care. Ontological situational ethics in culture and norms were noted in the constructs of competence, responsibility, solidarity with colleagues and organization; and interest and learning were driving forces. Ethical demand was evident when nurses expressed ideas of meaningfulness in helping their fellow humans; but themes of ambiguity, exhaustion and unwillingness were also present. Conclusions: The nurses showed a high willingness to care for patients during a crisis. Responding to the ethical demand and to care for vulnerable human beings while risking their own health and lives could be interpreted as an inter-human vocation. These spontaneous altruistic actions saved the lives of many patients during the pandemic and need to be understood and supported. (shrink)

Im Rahmen des Modellvorhabens „Patienten als Partner—Tumorpatienten und ihr Mitwirken bei medizinischen Entscheidungen“ wurden zwischen März 2002 und August 2003 272 palliativ behandelte Tumorpatienten nach ihrer Einstellung zur Patientenverfügung und zur gewünschten Beteiligung an medizinischen Entscheidungen befragt. Von den Befragten kannten 30% Patientenverfügungen nicht, darunter signifikant mehr Befragte mit formal niedrigerem Bildungsabschluss. Es hatten bereits 11% eine Patientenverfügung abgeschlossen, 22% wollten wahrscheinlich eine abschließen, und 30% wollten keine abschließen. Es fand sich ein statistisch signifikanter Zusammenhang zwischen dem Abschluss einer Patientenverfügung (...) und dem Wunsch nach mehr eigener Entscheidungsverantwortung. Die Einstellung zur Patientenverfügung und der Wunsch nach partizipativer Entscheidungsfindung stehen in keinem statistisch signifikanten Zusammenhang. Patienten mit schriftlichen Vorausverfügungen haben einen erhöhten Kommunikations- und Rückkopplungsbedarf, auf den Ärzte sensibel eingehen sollten. Bei der Information über Patientenverfügungen sollten Menschen mit niedrigerem Bildungsstand mehr als bisher berücksichtigt werden. (shrink)

Climate change and decarbonization raise complex justice questions that researchers and policymakers must address. The distributions of greenhouse gas emissions rights and mitigation efforts have dominated justice discourses within scenario research, an integrative element of the IPCC. However, the space of justice considerations is much larger. At present, there is no consistent approach to comprehensively incorporate and examine justice considerations. Here we propose a conceptual framework grounded in philosophical theory for this purpose. We apply this framework to climate mitigation scenarios (...) literature as proof of concept, enabling a more holistic and multidimensional investigation of justice. We identify areas of future research, including new metrics of service provisioning essential for human well-being. [Can be freely read by clicking the ReadCube link below.]. (shrink)

The present two-study paper examined the role of communication strategies that athletes use to develop their coach-athlete relationship. Study 1 examined the mediating role of motivation, support and conflict management strategies between the quality of the coach-athlete relationship and athletes’ perceptions of sport satisfaction. Study 2 examined the longitudinal and mediational associations of communication strategies and relationship quality across two time points, over a six-week period. Within both studies, data were collected through multi section questionnaires assessing the studies’ variables. For (...) study 1, structural equation modelling highlighted significant indirect effects for motivation and support strategies between the quality of the coach-athlete relationship and athletes’ experiences of sport satisfaction. For study 2, significant indirect effects were found for the athletes’ perceptions of the quality of the coach-athlete relationship at time 2 between athletes’ use of communication strategies at time point 1 and time point 2. Together these findings provide support for the practical utility of communications strategies in enhancing the quality of the coach-athlete relationship and athlete’s experiences of sport satisfaction. In addition, the findings provide evidence to highlight the potential cyclical relationship between communication and relationship quality across time. (shrink)

Purpose: To explain physical activity behavior, social-cognitive theories were most commonly used in the past. Besides conscious processes, the approach of dual processes additionally incorporates non-conscious regulatory processes into physical activity behavior theories. Habits are one of various non-conscious variables that can influence behavior and thus play an important role in terms of behavior change. The aim of this review was to examine the relationship between habit strength and physical activity behavior in longitudinal studies.Methods: According to the PRISMA guidelines, a (...) systematic search was conducted in three databases. Only peer-reviewed articles using a longitudinal study design were included. Both, habit and physical activity were measured at least once, and habit was related to physical activity behavior. Study quality was evaluated by assessment tools of the NHLBI.Results: Of 3.382 identified publications between 2016 and 2019, fifteen studies with different study designs were included. Most studies supported that positive correlations between habit and physical activity exist. Some positive direct and indirect effects of habit on physical activity were detected and only a minority of studies showed the influence of physical activity on habit strength. Studies differentiating between instigation and execution habit found positive correlations and revealed instigation habit as a stronger predictor of physical activity. The quality of studies was rated as reasonable using assessment tools of the NHLBI.Conclusion: This review revealed a bidirectional relationship between habit and physical activity. Whether habit predicts physical activity or vice versa is still unclear. The observation of habit influencing physical activity may be most appropriate in studies fostering physical activity maintenance while the influence of physical activity on habit may be reasonable in experimental studies with physical activity as intervention content to form a habit. Future investigations should differentiate between habit formation and physical activity maintenance studies depending on the research objective. Long-term study designs addressing the complexity of habitual behavior would be beneficial for establishing cue-behavior associations for the formation of habits. Furthermore, studies should differentiate between instigation and execution habit in order to investigate the influence of both variables on physical activity behavior independently. (shrink)

Background: Due to recent legislations on euthanasia and its current practice in the Netherlands and Belgium, issues of end-of-life medicine have become very vital in many European countries. In 2002, the Ethics Working Group of the German Association for Palliative Medicine (DGP) has conducted a survey among its physician members in order to evaluate their attitudes towards different end-of-life medical practices, such as euthanasia (EUT), physician-assisted suicide (PAS), and terminal sedation (TS). Methods: An anonymous questionnaire was sent to the 411 (...) DGP physicians, consisting of 14 multiple choice questions on positions that might be adopted in different hypothetical scenarios on situations of “intolerable suffering” in end-of-life care. For the sake of clarification, several definitions and legal judgements of different terms used in the German debate on premature termination of life were included. For statistical analysis t-tests and Pearson-correlations were used. Results: The response rate was 61% (n=251). The proportions of the respondents who were opposed to legalizing different forms of premature termination of life were: 90% opposed to EUT, 75% to PAS, 94% to PAS for psychiatric patients. Terminal sedation was accepted by 94% of the members. The main decisional bases drawn on for the answers were personal ethical values, professional experience with palliative care, knowledge of alternative approaches, knowledge of ethical guidelines and of the national legal frame. Conclusions: In sharp contrast to similar surveys conducted in other countries, only a minority of 9.6% of the DGP physicians supported the legalization of EUT. The misuse of medical knowledge for inhumane killing in the Nazi period did not play a relevant role for the respondents’ negative attitude towards EUT. Palliative care needs to be stronger established and promoted within the German health care system in order to improve the quality of end-of-life situations which subsequently is expected to lead to decreasing requests for EUT by terminally ill patients.

The ability to learn sequential contingencies of actions for predicting future outcomes is indispensable for flexible behavior in many daily decision-making contexts. It remains open whether such ability may be enhanced by transcranial direct current stimulation. The present study combined tDCS with functional near-infrared spectroscopy to investigate potential tDCS-induced effects on sequential decision-making and the neural mechanisms underlying such modulations. Offline tDCS and sham stimulation were applied over the left and right dorsolateral prefrontal cortex in young male adults in a (...) double-blind between-subject design using a three-state Markov decision task. The results showed an enhanced dlPFC hemodynamic response during the acquisition of sequential state transitions that is consistent with the findings from a previous functional magnetic resonance imaging study; a tDCS-induced increase of the hemodynamic response in the dlPFC, but without accompanying performance-enhancing effects at the behavioral level; and a greater tDCS-induced upregulation of hemodynamic responses in the delayed reward condition that seems to be associated with faster decision speed. Taken together, these findings provide empirical evidence for fNIRS as a suitable method for investigating hemodynamic correlates of sequential decision-making as well as functional brain correlates underlying tDCS-induced modulation. Future research with larger sample sizes for carrying out subgroup analysis is necessary in order to decipher interindividual differences in tDCS-induced effects on sequential decision-making process at the behavioral and brain levels.

The aim of this study was to investigate the consistency between the self-reports and teacher ratings of students’ emotional and social inclusion at school as well as for their academic self-concept. The German version of the Perceptions of Inclusion Questionnaire (PIQ) was administered to 329 grade 8 students (50.8% female, Mage = 14.5 years, SDage = 0.5 years) and their teachers. First, the three-dimensional structure of both PIQ versions was confirmed by confirmatory item factor analysis. The  and  coefficients (...) demonstrated good reliability for all scales. Second, a correlated trait-correlated method minus one model provided evidence that the method-specificity of teacher ratings was larger than the consistency between the self-reports and teacher ratings. Third, the results of a latent difference model indicated that general method effects can partly be explained by a student’s gender or special educational needs. Finally, the low consistency between self-reports and teacher rating is discussed. (shrink)

Three‐dimensional structured illumination microscopy (3D‐SIM) has opened up new possibilities to study nuclear architecture at the ultrastructural level down to the ∼100 nm range. We present first results and assess the potential using 3D‐SIM in combination with 3D fluorescence in situ hybridization (3D‐FISH) for the topographical analysis of defined nuclear targets. Our study also deals with the concern that artifacts produced by FISH may counteract the gain in resolution. We address the topography of DAPI‐stained DNA in nuclei before and after (...) 3D‐FISH, nuclear pores and the lamina, chromosome territories, chromatin domains, and individual gene loci. We also look at the replication patterns of chromocenters and the topographical relationship ofXist‐RNA within the inactive X‐territory. These examples demonstrate that an appropriately adapted 3D‐FISH/3D‐SIM approach preserves key characteristics of the nuclear ultrastructure and that the gain in information obtained by 3D‐SIM yields new insights into the functional nuclear organization.

Experiences of discrimination such as everyday racism can negatively affect the mental and physical health of children and adolescents with an immigrant background and impair their integration process in the host societies. Although experiences of racism are part of the everyday life of many minors affected by the process of “Othering”, an overview of empirical findings is missing for this age group worldwide. A systematic review was conducted to identify and analyze international research on the impact of discrimination on the (...) developmental outcomes and integration of immigrant children and adolescents. Three scientific databases were systematically searched up to June 11, 2021. A total of k = 4,769 identified publications were reviewed based on inclusion and exclusion criteria in terms of the PICOS format by independent reviewers. Thirty-four primary studies published between 1998 and 2021 met all inclusion criteria. The samples examined were mainly migrant youth, with only k = 2 studies assessing refugee youth and k = 1 study assessing both migrant and refugee youth. The majority of included studies assessed perceived discrimination, with only k = 1 study directly assessing experiences of racism. The association between discrimination or racism and developmental outcomes was assessed by the included studies within the three main topics of mental and physical health-related outcomes, school-related outcomes, and other developmental outcomes. Data collection procedures were implemented, and findings on minors’ developmental outcomes and integration process who experience discrimination and racism were summarized and discussed. The current review suggests experienced discrimination as a negative predictor of children and adolescents’ health-related outcomes, while no clear results could be found for the association between discrimination and school-related outcomes. A need for more empirical research focusing on the path and indirect link between discrimination and children and adolescents’ school-related outcomes as well as resulting school recommendations and the chosen career path was derived.Systematic Review Registration[https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=260291], identifier [CRD42021260291].

BackgroundThe SARS-COVID-19 pandemic and its associated disease control restrictions have in multiple ways affected families with young children, who may be especially vulnerable to mental health problems. Studies report an increase in perinatal parental distress as well as symptoms of anxiety or depression in children during the pandemic. Currently, little is known about the impact of the pandemic on infants and their development. Infant regulatory problems have been identified as early indicators of child socio-emotional development, strongly associated with maternal mental (...) health and the early parent–infant interaction. Our study investigates whether early parenthood under COVID-19 is associated with more maternal depressive symptoms and with a perception of their infants as having more RPs regarding crying/fussing, sleeping, or eating, compared to mothers assessed before the pandemic.MethodsAs part of a longitudinal study, 65 women who had given birth during the first nationwide disease control restrictions in Northern Germany, were surveyed at 7 months postpartum and compared to 97 women assessed before the pandemic. RPs and on maternal depressive symptoms were assessed by maternal report. Number of previous children, infant negative emotionality, and perceived social support were assessed as control variables.ResultsCompared to the control cohort, infants born during the COVID-19 pandemic and those of mothers with higher depressive symptoms were perceived as having more sleeping and crying, but not more eating problems. Regression-based analyses showed no additional moderating effect of parenthood under COVID-19 on the association of depressive symptoms with RPs. Infant negative emotionality was positively, and number of previous children was negatively associated with RPs.LimitationsDue to the small sample size and cross-sectional assessment, the possibility for more complex multivariate analysis was limited. The use of parent-report questionnaires to assess infant RPs can support but not replace clinical diagnosis.ConclusionsThe pandemic conditions affecting everyday life may have a long-term influence on impaired infant self- and maternal co-regulation and on maternal mental health. This should be addressed in peripartum and pediatric care. Qualitative and longitudinal studies focusing on long-term parental and infant outcomes under ongoing pandemic conditions are encouraged.

BackgroundParental reflective functioning refers to parents’ mental capacity to understand their own and their children’s behaviors in terms of envisioned mental states. As part of a broader concept of parental mentalization, PRF has been identified as one of the central predictors for sensitive parenting. However, the unique contribution of PRF to the quality of various parenting behaviors has not yet been addressed systematically. Thus, the present article provides a systematic overview of current research on the associations between PRF or its (...) sub-dimensions and observed parenting behaviors in infancy and early childhood, while considering the influence of contextual factors.MethodsThe review was conducted following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Systematic searches were carried out in five electronic databases. The eligibility and methodological quality of the identified studies were assessed using pre-defined criteria and a standardized checklist.ResultsSixteen studies with moderate to high quality on a total of 15 parenting behaviors were included, the majority of which examined positive parenting behaviors, while negative parenting behaviors were rarely investigated. Most of the associations indicated a positive effect of PRF on parenting behavior, with mostly small-sized effects. The strength and direction of the associations varied depending on the dimensionality of PRF, observation settings, sample types, socioeconomic factors, and cultural background. Moreover, five assessment instruments for PRF and 10 observation instruments for parenting behaviors were identified.ConclusionIn summary, PRF has shown a positive association with parenting quality. However, its complex interaction with further contextual factors emphasizes the need for differentiation of PRF dimensions and the consideration of the observation settings, assessment time points, psychosocial risks, and sample types in observational as well as intervention studies. Further high-quality studies with multivariate analyses and diverse study settings are required. (shrink)

Human–robot interactions are often affected by error situations that are caused by either the robot or the human. Therefore, robots would profit from the ability to recognize when error situations occur. We investigated the verbal and non-verbal social signals that humans show when error situations occur in human–robot interaction experiments. For that, we analyzed 201 videos of five human–robot interaction user studies with varying tasks from four independent projects. The analysis shows that there are two types of error situations: social (...) norm violations and technical failures. Social norm violations are situations in which the robot does not adhere to the underlying social script of the interaction. Technical failures are caused by technical shortcomings of the robot. The results of the video analysis show that the study participants use many head movements and very few gestures, but they often smile, when in an error situation with the robot. The results suggest that participants do not see the robot as a social interaction partner with comparable communication skills. Our findings have implications for builders and evaluators of human–robot interaction systems. The builders need to consider including modules for recognition and classification of head movements to the robot input channels. The evaluators need to make sure that the presence of an experimenter does not skew the results of their user studies. (shrink)

As we experience and manipulate time—be it as boredom or impatience—it becomes an object: something materialized and social, something that affects perception, or something that may motivate reconsideration and change. The editors and contributors to this important new book, _Ethnographies of Youth and Temporality, _have provided a diverse collection of ethnographic studies and theoretical explorations of youth experiencing time in a variety of contemporary socio-cultural settings. The essays in this volume focus on time as an external and often troubling factor (...) in young people’s lives, and shows how emotional unrest and violence but also creativity and hope are responses to troubling times. The chapters discuss notions of time and its and its “objectification” in diverse locales including the Georgian Republic, Brazil, Denmark and Uganda. Based on long-term ethnographic fieldwork, the essays in _Ethnographies of Youth and Temporality_ use youth as a prism to understand time and its subjective experience.

Today's societies are confronted by a daily biodiversity loss, which will increase in the face of climate change and environmental pollution. Biodiversity loss is a particularly severe problem in so-called biodiversity hotspots. Ecuador is an example of a country that hosts two different biodiversity hotspots. Human behavior - in developing as well as in industrial countries such as Germany - must be considered as one of the most important direct and indirect drivers of this global trend and thus plays a (...) crucial role in environmentalism and biodiversity conservation. Nature relatedness and environmental concern have been identified as important environmental psychological factors related to people's pro-environmental behavior. However, the human-nature relationship depends on a variety of other factors, such as values, gender, nationality, qualities of environmental concern and time spent in nature. This study compared young people from Ecuador and Germany with regard to their nature relatedness and environmental concern. Furthermore, the role of the aforementioned factors was investigated. In total, we surveyed 2,173 high school students from Germany (Mage = 14.56 years, SD = 1.45; female: 55.1%) and 451 high school students from Ecuador (Mage = 14.63 years, SD = 1.77; female: 55.3%). We found that young Ecuadorians were more related to nature than young people from Germany. Additionally, we found country-specific differences in the structure of environmental concern and in the role of gender in the explanation of biospheric environmental concern and nature relatedness. In both samples, the self-transcendence value cluster was a significant positive predictor for biospheric environmental concern and nature relatedness. Time spent in nature was a significant positive predictor for nature relatedness in both samples. The results are an empirical basis for the assumption of culture-specific differences in human-nature relationships. (shrink)

We analyzed the association between the analog and the digital home learning environment in toddlers’ and preschoolers’ homes, and whether both aspects are associated with children’s social and academic competencies. Here, we used data of the national representative sample of Growing up in Germany II, which includes 4,914 children aged 0–5 years. The HLE was assessed via parental survey that included items on the analog HLE and items on the digital HLE. Children’s socio-emotional, practical life skills, and academic competencies were (...) assessed via standardized parental ratings. Our results indicate that there are two dimensions of the HLE, an analog and a digital, that are slightly positively associated, especially in the toddler age group. For toddlers, only analog HLE activities were associated with better socio-emotional outcomes and practical life skills. However, interaction effects indicate that toddlers with less frequent analog HLE activities showed better socio-emotional skills in households with more frequent digital activities. For preschoolers, digital HLE activities were associated with weaker socio-emotional skills but higher academic skills, although the analog HLE shows higher effect sizes for the academic outcomes. Our study points out that analog and digital HLE activities seem to be partly associated, but not interchangeable. Further, they seem to be important variables that can explain individual differences in young children’s socio-emotional, practical life, and academic competencies. However, digital media usage at home may also have negative effects on children’s social–emotional competencies. This association needs to be investigated further. (shrink)

Through advances in production and treatment technologies, transparent glass has become an increasingly versatile material and a global hallmark of modern architecture. In the shape of invisible barriers, it defines spaces while simultaneously shaping their lighting, noise, and climate conditions. Despite these unique architectural qualities, little is known regarding the human experience with glass barriers. Is a material that has been described as being simultaneously there and not there from an architectural perspective, actually there and/or not there from perceptual, behavioral, (...) and social points of view? In this article, we review systematic observations and experimental studies that explore the impact of transparent barriers on human cognition and action. In doing so, the importance of empirical and multidisciplinary approaches to inform the use of glass in contemporary architecture is highlighted and key questions for future inquiry are identified.

The quality of the animal-human relationship and, consequently, the welfare of animals can be improved by gentle interactions such as stroking and talking. The perception of different stimuli during these interactions likely plays a key role in their emotional experience, but studies are scarce. During experiments, the standardization of verbal stimuli could be increased by using a recording. However, the use of a playback might influence the perception differently than ‘live’ talking, which is closer to on-farm practice. Thus, we compared (...) heifers’ (n = 28) reactions to stroking while an experimenter was talking soothingly (‘live’) or while a recording of the experimenter talking soothingly was played (‘playback’). Each animal was tested three times per condition and each trial comprised three phases: pre-stimulus, stimulus (stroking and talking) and post-stimulus. In both conditions, similar phrases with positive content were spoken calmly, using long low-pitched vowels. All tests were video recorded and analyzed for behaviors associated with different affective states. Effects on the heifers’ cardiac parameters were assessed using analysis of heart rate variability. Independently of the auditory stimuli, longer durations of neck stretching occurred during stroking, supporting our hypothesis of a positive perception of stroking. Observation of ear positions revealed longer durations of the back up position and less ear flicking and changes of ear positions during stroking. The predicted decrease in HR during stroking was not confirmed; instead we found a slightly increased mean HR during stroking with a subsequent decrease in HR, which was stronger after stroking with live talking. In combination with differences in HRV parameters, our findings suggest that live talking might have been more pleasurable to the animals and had a stronger relaxing effect than ‘playback’. The results regarding the effects of the degree of standardization of the stimulus on the variability of the data were inconclusive. We thus conclude that the use of recorded auditory stimuli to promote positive affective states during human-animal interactions in experimental settings is possible, but not necessarily preferable.

Research on dyscalculia in neurodegenerative diseases is still scarce, despite high impact on patients’ independence and activities of daily living function. Most studies address Alzheimer’s Disease; however, patients with Parkinson’s Disease also have a higher risk for cognitive impairment while the relation to arithmetic deficits in financial contexts has rarely been studied. Therefore, the current exploratory study investigates deficits in two simple arithmetic tasks in financial contexts administered within the Clinical Dementia Rating in a sample of 100 PD patients. Patients (...) were classified as cognitively normal or mildly impaired according to Level I consensus criteria, and assessed using a comprehensive neuropsychological test battery, neurological motor examination, and sociodemographic and clinical questionnaires. In total, 18% showed arithmetic deficits: they were predominately female, had longer disease duration, more impaired global cognition, but minor signs of depression compared to PD patients without arithmetic deficits. When correcting for clinical and sociodemographic confounders, greater impairments in attention and visuo-spatial/constructional domains predicted occurrence of arithmetic deficits. The type of deficit did not seem to be arbitrary but seemed to involve impaired place × value processing frequently. Our results argue for the importance of further systematic investigations of arithmetic deficits in PD with sensitive tests to confirm the results of our exploratory study that a specific subgroup of PD patients present themselves with dyscalculia.
