Cognitive control deployment is flexibly modulated by social value in early adolescence

Recent mechanistic models of cognitive control define the normative level of control deployment as a function of the effort cost of exerting control balanced against the reward that can be attained by exerting control. Despite these models explaining empirical findings in adults, prior literature has suggested that adolescents may not adaptively integrate value into estimates of how much cognitive control they should deploy. Moreover, much work in adolescent neurodevelopment casts social valuation processes as competing with, and in many cases overwhelming, cognitive control in adolescence. Here, we test whether social incentives can adaptively increase cognitive control. Adolescents (M_age = 14.64, 44 male, N = 87) completed an incentivized cognitive control task in which they could exert cognitive control to receive rewards on behalf of real peers who were rated by all peers in their school grade as being of either high- or low-status. Using Bayesian modeling, we find robust evidence that adolescents exert more cognitive control for high- relative to low-status peers. Moreover, we demonstrate that social incentives, irrespective of their high- or low-status, boost adolescent cognitive control above baseline control where no incentives are offered. Findings support the hypothesis that the cognitive control system in early adolescence is flexibly modulated by social value.

Parenting Characteristics Protective Against Substance Use and Deviant Peer Involvement in High-Risk Neighborhoods

Robust research shows that poor parenting practices are related to adverse outcomes among adolescents; however, few have examined the interaction between parenting variables and adolescent outcomes within the context of exposure to relentless crime. The current study examined the combined effects of parental monitoring and discipline on marijuana involvement and deviant peer affiliation among adolescent males living in Los Angeles neighborhoods with concentrated crime. For this study, areas with higher-than-average crime rates were selected based on census data, published statistics, and law-enforcement data. The study included 349 males between 13 and 17 years of age, mostly Latino (70.2%) and African American (28.4%). Data were collected using questionnaires to interview participants and analyzed using logistic regression. Results suggest that among adolescent males in geographic areas of high violence and crime, the interaction between parental monitoring and discipline was significantly related to marijuana involvement and deviant peer affiliation. Follow-up analyses showed parental monitoring was only an effective tool at higher levels of consistent parental discipline. In the absence of consistent discipline, good parental monitoring was ineffective at preventing marijuana involvement and affiliation with deviant peers. Results suggest that if time and resources are limited, clinicians should consider focusing on the use of consistent discipline with parents residing in high-crime neighborhoods.

     

Assessment of apathy in neurological patients using the Apathy Motivation Index caregiver version

Apathy is a common, disabling neuropsychiatric syndrome that occurs across many brain disorders and may be associated with diminished motivation in behavioural, cognitive, emotional and social domains. Assessment is complicated by the variability of symptoms across apathy domains and self-report from patients, which can be misleading due to their lack of insight. Independent evaluation by clinicians also has limitations though if it has to be performed with limited time. Caregiver reports are a viable alternative, but current assessments for them either do not distinguish between different apathy domains or are interview-based and take long to administer. In this study, we developed a brief caregiver questionnaire version of the recently developed Apathy Motivation Index (AMI), which is a self-report tool. We confirmed three apathy factors in this new caregiver measure (AMI-CG) that were also present in the AMI: Behavioural Activation, Emotional Sensitivity and Social Motivation. Furthermore, we validated the scores against more extensive caregiver interviews using the established Lillle apathy rating scale as well as patient self-reports of apathy, measures of depression, anhedonia, cognition, activities of daily living and caregiver burden across four different neurological conditions: Parkinson's disease, Alzheimer's disease, subjective cognitive impairment and limbic encephalitis. The AMI-CG showed good internal reliability, external validity and diagnostic accuracy. It also uncovered cases of social apathy overlooked by traditional instruments. Crucially, patients who under-rated their apathy compared to informants were more likely to have difficulties performing everyday activities and to be a greater burden to caregivers. The findings provide evidence for a multidimensional conceptualization of apathy and an instrument for efficient detection of apathy based on caregiver reports for use in clinical practice.     

Changes in body image during cognitive-behavioral treatment in women with bulimia nervosa

The purposes of this study were: (1) to examine multidimensional aspects of body image of individuals with bulimia nervosa (BN) at pre-treatment, post-treatment, and at follow-up, compared to a group of participants without BN; and (2) to investigate whether measures of body image predicted outcome at post-treatment and follow-up. The clinical sample consisted of 109 females with BN who were enrolled in a 12-week cognitive-behavioral group treatment program. Participants were assessed at baseline, at the completion of treatment, and at 1- and 6-month follow-up visits. The 82 females who comprised the non-bulimic sample were assessed at comparable time intervals. At baseline, the participants with BN reported greater body dissatisfaction and overestimated body size to a significantly greater degree than the comparison group, and reported a significantly smaller ideal size relative to perceived size. Results at the end of treatment indicated significant improvement in self-reported attitudinal disturbance and size overestimation, with continued reductions at follow-up. Logistic regression analyses did not demonstrate a predictive relationship between body image measures at baseline and outcome at post-treatment or follow-up, or between post-treatment and follow-up. Implications for treatment include specifying the source of body image-related distress and enhancing treatment efforts for perceptual and attitudinal aspects of body image.     

The value of fame: preadolescent perceptions of popular media and their relationship to future aspirations

In line with Greenfield's (2009) theory of social change and human development, current popular preadolescent TV shows suggest that fame, an individualistic goal, is an important and achievable aspiration (Uhls & Greenfield, 2011). Such messages may be particularly salient for preadolescents, ages 10-12. This study used focus groups and mixed analytic methods (qualitative and quantitative) to examine how popular media, passive and interactive, are interpreted by preadolescents and how their interpretations relate to their media practices and future goals. Quantitative analysis revealed that fame was the number one value, selected as the most important value for participants' future goals significantly more frequently than expected by chance. Qualitative analysis of focus group discourse suggested that (a) youth absorb messages in their media environment regarding fame as a future goal and (b) their interpretations of these messages highlight the importance and value of public recognition. Enacting the value of fame, the majority of preadolescent participants use online video sharing sites (e.g., YouTube) to seek an audience beyond their immediate community.     

The evolutionary basis of risky adolescent behavior: implications for science, policy, and practice

This article proposes an evolutionary model of risky behavior in adolescence and contrasts it with the prevailing developmental psychopathology model. The evolutionary model contends that understanding the evolutionary functions of adolescence is critical to explaining why adolescents engage in risky behavior and that successful intervention depends on working with, instead of against, adolescent goals and motivations. The current article articulates 5 key evolutionary insights into risky adolescent behavior: (a) The adolescent transition is an inflection point in development of social status and reproductive trajectories; (b) interventions need to address the adaptive functions of risky and aggressive behaviors like bullying; (c) risky adolescent behavior adaptively calibrates over development to match both harsh and unpredictable environmental conditions; (d) understanding evolved sex differences is critical for understanding the psychology of risky behavior; and (e) mismatches between current and past environments can dysregulate adolescent behavior, as demonstrated by age-segregated social groupings. The evolutionary model has broad implications for designing interventions for high-risk youth and suggests new directions for research that have not been forthcoming from other perspectives.     

Explaining variance in long-term recall in 3- and 4-year-old children: The importance of post-encoding processes

Long-term recall is influenced by what originally was encoded as well as by the efficacy of retrieval processes. The possible explanatory role of post-encoding processes by which initially labile memory traces are stabilized and integrated into long-term memory (i.e., consolidated) has received relatively less research attention. In the current research, we examined 3- and 4-year-old children's recall of multi-step event sequences immediately after seeing them modeled as a measure of encoding, 1week later as a measure of the status of the memory trace post-encoding, and 1month later as an assessment of long-term recall. We tested recall of events with three different levels of internal structure and with three different levels of support for retrieval. Measures of the post-encoding status of the memory trace explained significant variance in long-term recall when they were the sole predictors of performance, and they contributed unique variance in long-term recall even after accounting for the variance associated with encoding. The results imply that a complete explanation of forgetting during childhood must include not only roles for encoding and retrieval processes but also roles for post-encoding processes.
