Differential effects of aging on processes underlying task switching

In this study, we used event-related brain potentials (ERPs) to examine the effects of aging on processes underlying task switching. The response time data revealed an age-related increase in mixing costs before controlling for general slowing and no effect of aging on switching costs. In the cue-locked epoch, the ERP data revealed little effect of age on the parietal P3 related to cue encoding, an age-related decrease in parietal activity related to cue retrieval, and an age-related increase in the amplitude of the parietal and frontal activity related to task set configuration and rule mapping. In the target-locked epoch, there was differential neural recruitment in younger and older adults in response to task mixing. These data are consistent with the idea that older adults may not fully implement task set before onset of the target stimulus.     

Unveiling a reflective diary methodology for exploring the lived experiences of stress and coping

This article unveils a diary methodology exploring accounts of ongoing experiences during the final furlong of university life and examines the role of diary keeping for gaining insights into stress and coping with performance-related and general life stressors. The focus is on thirty young people who, following a year working in industry, were in the midst of their final year of university study—undergoing coursework assessments, preparing for final examinations, making key career choices, and taking part in the whole process of job applications, assessment centres, and interviews. All were attending a course exploring theoretical and practical approaches to self-awareness and interpersonal skills development. The article shares insights regarding the use of diaries for the exploration of stress and coping from the perspective of both the researcher and the diarist.     

Longitudinal development of manual motor ability in autism spectrum disorder from childhood to mid‐adulthood relates to adaptive daily living skills

Many individuals with autism spectrum disorder (ASD) exhibit motor difficulties, but it is unknown whether manual motor skills improve, plateau, or decline in ASD in the transition from childhood into adulthood. Atypical development of manual motor skills could impact the ability to learn and perform daily activities across the life span. This study examined longitudinal grip strength and finger tapping development in individuals with ASD (n = 90) compared to individuals with typical development (n = 56), ages 5 to 40 years old. We further examined manual motor performance as a possible correlate of current and future daily living skills. The group with ASD demonstrated atypical motor development, characterized by similar performance during childhood but increasingly poorer performance from adolescence into adulthood. Grip strength was correlated with current adaptive daily living skills, and Time 1 grip strength predicted daily living skills eight years into the future. These results suggest that individuals with ASD may experience increasingly more pronounced motor difficulties from adolescence into adulthood and that manual motor performance in ASD is related to adaptive daily living skills.     

Enjeux majeurs de santé publique versus autonomie personnelle : le cas spécifique de l’obligation vaccinale

While the triple individual, altruistic and collective dimension of the preventive vaccination obligation serves a major public health objective, it only prevents such a choice by public authorities, by imposing a constraint on individuals and thus violating several of their fundamental rights, from going against personal freedom. The first question raised is then that of the legitimacy of such a policy. Could less coercive means, and therefore less intrusive on fundamental rights and freedoms, not be deployed? If not, at what risk alert threshold(s) could the vaccination obligation be justified?     

The effects of attention on perceptual implicit memory

Reports on the effects of dividing attention at study on subsequent perceptual priming suggest that perceptual priming is generally unaffected by attentional manipulations as long as word identity is processed. We tested this hypothesis in three experiments by using the implicit word fragment completion and word stem completion tasks. Division of attention was instantiated with the Stroop task in order to ensure the processing of word identity even when the participant's attention was directed to a stimulus attribute other than the word itself. Under these conditions, we found that even though perceptual priming was significant, it was significantly reduced in magnitude. A stem cued recall test in Experiment 2 confirmed a more deleterious effect of divided attention on explicit memory. Taken together, our findings delineate the relative contributions of perceptual analysis and attentional processes in mediating perceptual priming on two ubiquitously used tasks of word fragment completion and word stem completion.     

Knowing when to hold ‘em: regret and the relation between missed opportunities and risk taking in children,adolescents and adults

Regret over missed opportunities leads adults to take more risks. Given recent evidence that the ability to experience regret impacts decisions made by 6-year-olds, and pronounced interest in the antecedents to risk taking in adolescence, we investigated the age at which a relationship between missed opportunities and risky decision-making emerges, and whether that relationship changes at different points in development. Six- and 8-year-olds, adolescents and adults completed a sequential risky decision-making task on which information about missed opportunities was available. Children also completed a task designed to measure their ability to report regret when explicitly prompted to do so. The relationship between missed opportunities and risky decision-making did not emerge until 8 years, at which age it was associated with the ability to explicitly report regret, and was stronger in adults than in adolescents. These novel results highlight the potential importance of the ability to experience regret in children and adolescents’ risky decision-making.     

Validating Childhood Maltreatment Typologies Using Data Linkage

This data linkage study aims to examine associations between subgroups of child maltreatment and a range of demographic (e.g., gender) familial (e.g., parental unemployment) and health outcomes. Structured interviews were conducted on 2,980 participants. Data were then linked with information drawn from Danish registries. Multinomial logistic regression analyses indicated out-of-home-care was a shared risk for all forms of maltreatment relative to nonmaltreated controls. Sexual and co-occurring abuse groups had strong associations with psychiatric outcomes at age 21. Findings emphasize how a child’s early environment can impact health, highlighting the need for targeted interventions encompassing a range of risk factors at an early age.     

Reasons for the “after-school pressure cooker” in Affluent Communities: It’s Not How Much Time,but Why

This study extends the over-scheduling hypothesis literature by focusing on affluent adolescents and exploring relations between psychosocial adjustment and reasons for organized activity (OA) involvement rather than focusing solely on time spent in OAs. Variable- and person-centered analyses were used to evaluate associations between intensity of OA participation and reasons for involvement, perceived parental pressure, and adjustment (depressive symptoms, anxiety symptoms, life satisfaction) in a sample of 10th graders (N = 122) from affluent communities. When adolescents’ perceptions of parental pressure were controlled for in analyses, more intensely involved youth reported lower levels of depressive symptoms. “For Fun” was the most highly rated reason for involvement and was linked to lower levels of perceived parental pressure, but was unrelated to all indicators of adjustment. Conversely, involvement in OAs “for Parents” was linked to more perceived parental pressure and lower levels of life satisfaction. Two OA participant profiles emerged in person-centered analyses: (1) primarily intrinsic reasons (high Fun, moderate Future, low Parents) and (2) intrinsic and extrinsic reasons (high Fun, high Future, high Parents) for involvement. OA participation simultaneously motivated by extrinsic and intrinsic reasons was linked to fewer psychosocial benefits than intrinsically motivated OA involvement.
