The effects of co‐occurring ADHD symptoms on electrophysiological correlates of cognitive control in young people with Tourette syndrome

Efficient cognitive control is implicated in tic control in young people with Tourette syndrome (TS). Attention‐deficit/hyperactivity disorder (ADHD) frequently co‐occurs with TS and is associated with impaired cognitive control. Young people with TS and ADHD (TS+ADHD) show poorer cognitive control performance than those with TS, but how co‐occurring ADHD affects underlying neural activity is unknown. We investigated this issue by examining behavioural and event‐related potential (ERP) correlates of cognitive control in young people with these conditions. Participants aged 9–17 with TS (n = 17), TS+ADHD (n = 17), ADHD (n = 11), and unaffected controls (n = 20) performed a visual Go/Nogo task during electroencephalography (EEG) recording. Behavioural performance measures (D‐prime, RT, reaction time variability, post‐error slowing) and ERP measures (N2, P3, error‐related negativity (ERN), error positivity (Pe)) were analysed in a 2 (TS‐yes, TS‐no) × 2 (ADHD‐yes, ADHD‐no) factorial analysis to investigate the effects of TS, ADHD, and their interaction. The results of these analyses showed that ADHD was associated with poorer performance and reduced amplitude of all ERPs, reflecting widespread cognitive control impairments. Tourette syndrome was associated with slowed RTs, which might reflect a compensatory slowing of motor output to facilitate tic control. There was no interaction between the TS and ADHD factors for any behavioural or ERP measure, indicating the impairing effects of ADHD on behaviour and electrophysiological markers of cognitive control were present in TS+ADHD and that RT slowing associated with TS was unaffected by co‐occurring ADHD symptoms.     

Affective and cognitive religiosity: Influences on consumer reactance and self‐control

Self‐control is regularly studied in the marketing literature in relation to spending and food consumption; however, little research has assessed trait characteristics that influence consumers' self‐control. Although prior research in other fields has shown a generally positive relationship between religiosity and self‐control, such research has often used poor measures of religiosity and has inadequately examined marketplace outcomes or factors underlying consumers' self‐controlled responses. Thus, the studies herein build on self‐regulation theory to address and extend from these limitations by examining the influence of religiosity, as a multidimensional construct (particularly affective and cognitive religiosity), on self‐control and resulting influences on marketplace behaviors. Findings reveal that priming affectively (cognitively) religious consumers leads to greater (lower) consumer self‐control with a religious message prime (Study 1) and religious writing task (Study 2). Additionally, findings show that psychological reactance is at the root of these responses (Study 3). Implications build on self‐regulation theory and the strength model of self‐control to show the importance of religiosity (particularly affective and cognitive religiosity), interactions with religious primes, and psychological reactance in understanding consumers' self‐control.     

Emotional adjustment in victims and perpetrators of cyberbullying and traditional bullying

Given the rise in cyberbullying among secondary education students and the importance of certain psychological adjustment variables for the comprehension of this type of violent behavior, both in bullies and in victims, the purpose of the present study was to analyse the emotional adjustment of those involved in cyber- and traditional bullying. The adjustment variables studied were self-concept, perceived stress, loneliness, depressive symptomatology, social anxiety, life satisfaction, and emotional intelligence. Using a sample of 1318 adolescents (47% boys), aged between 11 and 17 years, four groups were established to compare victims and cybervictims (uninvolved students, traditional victims, cybervictims, and traditional–cybervictims). The analysis of variance showed that students who performed the same role (bully or victim) in both contexts (at school and online). In particular, those who suffered traditional or cyberbullying or both conjointly presented lower scores in physical and social self-concept, life satisfaction, emotional clarity, and emotion regulation, as well as higher scores in perceived stress, loneliness, depression, and social anxiety. In bullies—traditional, cyberbullying or both simultaneously—higher scores were observed in perceived stress, loneliness, depressive symptomatology, fear of negative assessment, avoidance, and general social anxiety, and lower scores in the dimensions of academic and family self-concept, life satisfaction, emotional clarity, and emotion regulation. In general, the findings indicate that students who were involved in bullying situations, both victims and bullies, presented more damaged emotional profiles than those who are uninvolved, especially students who performed the same role (bully or victim) in both contexts (at school and online).

     

Perceiving a calling, living a calling, and job satisfaction: testing a moderated, multiple mediator model

The current study examined the relation between perceiving a calling, living a calling, and job satisfaction among a diverse group of employed adults who completed an online survey (N = 201). Perceiving a calling and living a calling were positively correlated with career commitment, work meaning, and job satisfaction. Living a calling moderated the relations of perceiving a calling with career commitment and work meaning, such that these relations were more robust for those with a stronger sense they were living their calling. Additionally, a moderated, multiple mediator model was run to examine the mediating role of career commitment and work meaning in the relation of perceiving a calling and job satisfaction, while accounting for the moderating role of living a calling. Results indicated that work meaning and career commitment fully mediated the relation between perceiving a calling and job satisfaction. However, the indirect effects of work meaning and career commitment were only significant for individuals with high levels of living a calling, indicating the importance of living a calling in the link between perceiving a calling and job satisfaction. Implications for research and practice are discussed.     

On matters of mind and body: regarding Descartes

In this paper the author considers Descartes’ place in current thinking about the mind‐body dilemma. The premise here is that in the history of ideas, the questions posed can be as significant as the answers acquired. Descartes’ paramount question was ‘How do we determine certainty?’ and his pursuit of an answer led to cogito ergo sum. His discovery simultaneously raised the question whether mind is separate from or unified with the body. Some who currently hold that brain and subjectivity are unified contend that the philosopher ‘split’ mind from body and refer to ‘Descartes’ error’. This paper puts forward that Descartes’ detractors fail to recognise Descartes’ contribution to Western thought, which was to introduce the Enlightenment and to give a place to human subjectivity. Added to this, evidence from Descartes’ correspondence with Princess Elisabeth of Bohemia supports the conclusion that Descartes did in fact believe in the unity of mind and body although he could not reconcile this rationally with the certainty from personal experience that they were separate substances. In this Descartes was engaged in just the same dilemma as that of current thinkers and researchers, a conflict which still is yet to be resolved.     

Changing Jobs and Changing Chores? The Longitudinal Association of Women’s and Men’s Occupational Gender-Atypicality and Couples’ Housework Performance

Prior research linking occupational sex composition (the proportion of women in an occupation) to housework has yielded conflicting results and relies exclusively on cross-sectional data. The present article extends scholarship on the gendered division of household labor by using longitudinal data from the Panel Study of Income Dynamics (PSID) 1981–2013 to assess how changes in occupational sex composition alter heterosexual married couples’ housework performance over time. I find that either spouse’s gender-atypical employment (e.g., husband’s employment in a predominately female job) is associated with gender-atypical housework performance by both spouses (e.g., higher housework hours for the husband and fewer hours for the wife). The association of women’s occupational sex composition with housework is driven by changes in individual women’s occupations and both spouses’ housework over time. In contrast, the association of men’s occupational sex composition with housework is driven by differences between different couples, not by within-couple change over time. Thus, fundamentally different causal mechanisms link women’s and men’s occupational sex composition to couples’ housework performance, and only for women are longitudinal changes in occupational sex composition associated with changes in housework. These findings have important implications for understanding occupation and housework as domains of gender performance.
