Is there heightened sensitivity to social reward in adolescence?

During adolescence, individuals are particularly susceptible to social influence. One explanation for this is that social stimuli have a heightened reward value at this age. To date, most evidence for heightened social reward in adolescence is found in the animal literature. Human adolescents show increased activation in fronto-striatal brain regions to rewarding social stimuli, but also to negative social stimuli, suggesting that adolescence may be a period of hypersensitivity to all social stimuli. Additional evidence from humans and animals suggest that the presence of others may heighten the value of non-social rewards; these findings should be incorporated into theories of social reward in adolescence

Affective bias and current, past and future adolescent depression: A familial high risk study.

Affective bias is a common feature of depressive disorder. However, a lack of longitudinal studies means that the temporal relationship between affective bias and depression is not well understood. One group where studies of affective bias may be particularly warranted is the adolescent offspring of depressed parents, given observations of high rates of depression and a severe and impairing course of disorder in this group

Genetic Duties

Most of our genetic information does not change, yet the results of our genetic tests might. Labs reclassify genetic variants in response to advances in genetic science. As a result, a person who took a test in 2010 could take the same test with the same lab in 2020 and get a different result. However, no legal duty requires labs or physicians to inform patients when a lab reclassifies a variant, even if the reclassification communicates clinically actionable information. This Article considers the need for such duties and their potential challenges. In so doing, it offers much-needed guidance to physicians and labs, who may face liability, and to courts, which will hear these cases

Are mental health awareness efforts contributing to the rise in reported mental health problems? A call to test the prevalence inflation hypothesis

In the past decade, there have been extensive efforts in the Western world to raise public awareness about mental health problems, with the goal of reducing or preventing these symptoms across the population. Despite these efforts, reported rates of mental health problems have increased in these countries over the same period. In this paper, we present the hypothesis that, paradoxically, awareness efforts are contributing to this reported increase in mental health problems. We term this the prevalence inflation hypothesis. First, we argue that mental health awareness efforts are leading to more accurate reporting of previously under-recognised symptoms, a beneficial outcome. Second, and more problematically, we propose that awareness efforts are leading some individuals to interpret and report milder forms of distress as mental health problems. We propose that this then leads some individuals to experience a genuine increase in symptoms, because labelling distress as a mental health problem can affect an individual's self-concept and behaviour in a way that is ultimately self-fulfilling. For example, interpreting low levels of anxiety as symptomatic of an anxiety disorder might lead to behavioural avoidance, which can further exacerbate anxiety symptoms. We propose that the increase in reported symptoms then drives further awareness efforts: the two processes influence each other in a cyclical, intensifying manner. We end by suggesting ways to test this hypothesis and argue that future awareness efforts need to mitigate the issues we present

Age-related differences in social influence on risk perception depend on the direction of influence

Adolescents are particularly susceptible to social influence. Here, we investigated the effect of social influence on risk perception in 590 participants aged eight to fifty-nine-years tested in the United Kingdom. Participants rated the riskiness of everyday situations, were then informed about the rating of these situations from a (fictitious) social-influence group consisting of teenagers or adults, and then re-evaluated the situation. Our first aim was to attempt to replicate our previous finding that young adolescents are influenced more by teenagers than by adults. Second, we investigated the social-influence effect when the social-influence group's rating was more, or less, risky than the participants' own risk rating. Younger participants were more strongly influenced by teenagers than by adults, but only when teenagers rated a situation as more risky than did participants. This suggests that stereotypical characteristics of the social-influence group – risk-prone teenagers - interact with social influence on risk perception

“I Wasn’t Sure What It Meant to be Honest”—Formative Research towards a Physical Literacy Intervention for Preschoolers

Physical literacy (PL) as a concept is important in developing lifelong physical activity; however, there is little research exploring how PL can be developed during the preschool years. This two-phase qualitative study sought the insights of academics/expert practitioners and preschool staff towards PL in order to inform the design of future preschool PL interventions. Phase One comprised of nine semi-structured interviews with experts in the field of children’s physical activity and/or PL. Interview topics included perspectives on the concept of PL and recommendations for interventions targeted at improving preschool PL. Phase Two consisted of focus groups with practitioners from four local children’s centres. Focus groups explored perspectives on the feasibility and acceptability of proposed PL interventions. Interviews and focus groups were analysed by thematic analysis and means of representation, respectively. Findings revealed that whilst there was limited understanding about the concept of PL among preschool educators, knowledge of child development was evident and that all participants agreed that there was a need for further training for practitioners. Perceived barriers to promoting PL noted by practitioners included funding, policy, curricular priorities, parental opinions, and the preschool environment. It was recommended that interventions should be: (i) designed using a participatory approach including all key stakeholders, (ii) conducted over the long term, and (iii) incorporate opportunities for children to engage in free and outdoor play. Furthermore, any intervention should be flexible to allow for variation between children’s centres, aligned to current policy/children’s centre targets and provide training and resources in order to overcome perceived barriers.</jats:p

The effect of social preference on academic diligence in adolescence

In the current study, we were interested in whether adolescents show a preference for social stimuli compared with non-social stimuli in the context of academic diligence, that is, the ability to expend effort on tedious tasks that have long-term benefits. Forty-five female adolescents (aged 11–17) and 46 female adults (aged 23–33) carried out an adapted version of the Academic Diligence Task (ADT). We created two variations of the ADT: a social ADT and non-social ADT. Individuals were required to freely split their time between an easy, boring arithmetic task and looking at a show-reel of photographs of people (in the social ADT) or landscapes (in the non-social ADT). Individuals also provided enjoyment ratings for both the arithmetic task and the set of photographs they viewed. Adolescents reported enjoying the social photographs significantly more than the non-social photographs, with the converse being true for adults. There was no significant difference in the time spent looking at the social photographs between the adolescents and adults. However, adults spent significantly more time than adolescents looking at the non-social photographs, suggesting that adolescents were less motivated to look at the non-social stimuli. Further, the correlation between self-reported enjoyment of the pictures and choice behaviour in the ADT was stronger for adults than for adolescents in the non-social condition, revealing a greater discrepancy between self-reported enjoyment and ADT choice behaviour for adolescents. Our results are discussed within the context of the development of social cognition and introspective awareness between adolescence and adulthood
