Daily motivation of volunteers in healthcare organizations: relating team inclusion and intrinsic motivation using self-determination theory

The work of volunteers is indispensable for the well functioning of healthcare organizations, and for maintaining the quality of care in times of austerity. As feelings of intrinsic motivation stimulate volunteer well-being and their long-term engagement, we study how team inclusion relates to volunteers’ intrinsic motivation during their activities. We hypothesize that volunteers’ perceptions of inclusion are positively related to intrinsic motivation, via the satisfaction of their basic needs for autonomy, competence, and relatedness. To test our hypothesis, we conducted a daily-diary study, obtaining a final sample of 43 volunteers and 204 completed diaries. Multilevel path analyses showed that team inclusion was positively related to volunteers’ intrinsic motivation during their activities. Subsequent mediation analyses revealed that competence and relatedness need satisfaction mediated this relationship. Thus, when volunteers feel part of the team with which they complete their activities, they experience intrinsic motivation because feeling included stimulates their feelings of being competent and being related to others.     

The Combined Effect of Neuropsychological and Neuropathological Deficits on Instrumental Activities of Daily Living in Older Adults: a Systematic Review

To date, studies have consistently demonstrated associations between either neuropsychological deficits or neuroanatomical changes and instrumental activities of daily living (IADL) in aging. Only a limited number of studies have evaluated morphological brain changes and neuropsychological test performance concurrently in relation to IADL in this population. As a result, it remains largely unknown whether these factors independently predict functional outcome. The current systematic review intended to address this lack of information by reviewing the literature on older adults, incorporating studies that examined e.g., normal aging, but also stroke or dementia patients. A comprehensive search of databases (Pubmed, Embase, Medline, Web of Science, PsycINFO) and reference lists was performed, focusing on papers in the English language that examined the combined effect of neuropsychological and neuroanatomical factors on IADL in samples of adults with an average age above 50. In total, 58 potential articles were identified; 20 were included in the review. The results show that especially neuropsychological variables (primarily memory and executive functions) independently predict IADL. Although some unique predictive value of brain morphological changes, such as hippocampal atrophy, was found, support for the importance of white matter changes was limited. However, the results of the studies reviewed are diverse, and appear to be at least partially determined by the variables included. For example, studies were less likely to find an independent effect of cognition if they solely employed a cognitive screening instrument. This indicates that a structured examination of neuroanatomical and neuropsychological correlates of IADL in different patient populations is warranted.     

Neuroticism,Extraversion, Perceived Social Support,and Escape Television Viewing as Determinants of Psychological Distress in Crime Victims

This study describes a longitudinal analysis of the relationship among neuroticism, extraversion, educational level, perceived social support, escape viewing, and psychological distress in crime victims. A sample of 170 crime victims completed self-report measures of these concepts. Personality traits, educational level, and baseline rates at 3 months postcrime of perceived social support and escape television viewing were modeled as predictors of psychological distress at 6 and 9 months postcrime. Neuroticism and extraversion significantly predicted psychological distress following victimization. Escape viewing had direct effects on distress and mediated the relationship between neuroticism and distress. Distress symptoms at 3 months were the strongest predictors of distress at 6 and 9 months postcrime.     

Waiting impulsivity: a distinctive feature of ADHD neuropsychology?

Impulsivity is a core feature of attention-deficit hyperactivity disorder (ADHD). It has been conceptualized in a number of different ways. In the current article, we examine how the new concept of “waiting impulsivity”, which refers to premature responding before a scheduled target appears, adds to our understanding of impulsivity in ADHD. Sixty children (8–12 years old; 30 ADHD; 30 typically developing controls) completed the 4-choice serial reaction time task, a measure of waiting impulsivity, alongside tasks measuring inhibitory control and temporal discounting and questionnaires measuring behavioral disorder symptoms, delay aversion, and various aspects of impulsivity. A multiple logistic regression model was used to explore the contribution of the primary task outcomes to predict group membership. Children with ADHD displayed more waiting impulsivity and less inhibitory control; they did not differ in temporal discounting. There was no correlation between waiting impulsivity and inhibitory control. Waiting impulsivity was correlated with parent-reported ratings of hyperactivity/impulsivity, inattention, oppositional defiant disorder (ODD), and conduct disorder (CD) and with self-reported delay aversion ratings. Only waiting impulsivity was a significant predictor of ADHD status. In conclusion, waiting impulsivity is distinct from inhibitory control deficits and predicts ADHD status independently of it. Future research needs to examine the relationship with delay aversion and ODD/CD more thoroughly.     

How to Define a Number? A General Epistemological Account of Simon Stevin’s Art of Defining

This paper explores Simon Stevin’s l’Arithmétique of 1585, where we find a novel understanding of the concept of number. I will discuss the dynamics between his practice and philosophy of mathematics, and put it in the context of his general epistemological attitude. Subsequently, I will take a close look at his justificational concerns, and at how these are reflected in his inductive, a postiori and structuralist approach to investigating the numerical field. I will argue that Stevin’s renewed conceptualisation of the notion of number is a sort of “existential closure” of the numerical domain, founded upon the practice of his predecessors and contemporaries. Accordingly, I want to make clear that l’Aritmetique have to be read not as an ontological analysis or exploration of the numerical field, but as an explication of a mathematical ethos. In this sense, this article also intends to make a specific contribution to the broader issue of the “ethics of geometry.”     

The enigmatic “nature of the subject”

Freud once placed psychoanalysis in a “middle position between medicine and philosophy”. Yet, the meaning of that position has never been sufficiently clarified. The author suggests that the essence of the psychoanalytic experience is defined by the fact that its clinical practice operates within a basically relational or intersubjective frame containing the analysand's self-interpreting reflection, which here is identified as ethical in nature. It is further argued that late modernity is experiencing a crisis in the art of reflection, accompanied by a flight from this ethical dimension. A common social response is to fall back on the authority of neo-positivistic science, making psychoanalysis increasingly redundant. To meaningfully connect with the consequences of this state of affairs, psychoanalysis needs to deepen the understanding of its unique essence. To that end, a model for collaboration with philosophy is briefly sketched.     

Correction of Effects of Memory Valence and Emotionality on Content and Style of Judgements

Research on interactions of emotional and cognitive processes provides evidence for congruency effects in the content and style of cognitive processing. This experiment investigated if and how these two kinds of bias can be compensated for. Participants were 194 undergraduates (mean age 22.58 years, SD = 4.85), who were asked to recall a positive or negative autobiographical memory in either an emotional or detached manner; half of the participants later received a suggestion to compensate for the effects of their moods. All participants then made judgements about the likelihood of future events. Interactions of Memory Valence, Emotionality, and Correction replicated the mood-congruency effects found in other research. Three aspects qualified the results. First, content congruency was found in both emotional and unemotional conditions. Furthermore, this content congruency was corrected for under emotional recall of positive and negative events, although less completely with positive events. Second, the undifferentiated judgement style of positive moods was also corrected for. Third, different correction procedures for styles of judgement were used, depending on whether participants experienced positive or negative moods. The results were discussed with regard to mood congruency and the cognitive-priming and feelings-as-information hypothesis.
