Evidence for a young adult face bias in accuracy and consensus of age estimates

Adults' face processing may be specialized for the dimensions of young adult faces. For example, young and older adults exhibit increased accuracy in normality judgments and greater agreement in attractiveness ratings for young versus older adult faces. The present study was designed to examine whether there is a similar young adult face bias in facial age estimates. In Experiment 1, we created a face age continuum by morphing an averaged young adult face with an averaged older adult face in 5% increments, for a total of 21 faces ranging from 0 to 100% old. Young and older adults estimated facial age for three stimulus age categories [young (morphs 0–30%), middle‐aged (morphs 35–65%), and older adult (morphs 70–100%)]. Both age groups showed the least differentiation in age estimates for young adult faces, despite showing greater consensus across participants in estimates for young faces. In Experiment 2, young and older adults made age estimates for individual young and older adult identities. Both age groups were more accurate and showed greater consensus in age estimates for young faces. Collectively, these results provide evidence for a bias in processing young adult faces beyond that which is often observed in recognition and normality/attractiveness judgment tasks.     

The Moral Community Divide: Underage Marijuana Use Across Religious Contexts

Compared to individual‐level research on religion and marijuana use, much less research has been conducted to investigate how the overall religious context of a geographic location may influence marijuana use during adolescence and early adulthood. Using multilevel analyses on two waves of the National Study of Youth and Religion (NSYR) merged with county‐level variables from the U.S. Census and the Religious Congregations and Membership Study (RCMS), this study finds that a county's higher Catholic population share is negatively associated with underage marijuana use frequency even after controlling for a wide range of individual and county‐level variables. Besides being robust, the Catholic contextual effect on marijuana use is also diffusive, influencing both Catholic and non‐Catholic youth who live in the same county. This study highlights the importance of viewing religious influence on substance use as a contextual, cultural force across different kinds of religious moral communities.     

Similarity to prototypical heavy drinkers and non-drinkers predicts AUDIT-C and risky drinking in young adults: prospective study

Objective: The aim of the present study was to explore whether constructs within the Prototype Willingness Model (PWM) predicted risky drinking as measured by AUDIT-C, drinking harms and unplanned drunkenness in a sample of UK young adults. Previous studies exploring the PWM often do not use validated measures of alcohol consumption, and the outcomes of risky drinking are underexplored. Design: An online prospective study design with 4 week follow-up was employed and 385 young adults completed the study (M age?=?21.76, SD?=?3.39, 69.6% female; 85.2% students). Main outcome measures: Intentions to get drunk, AUDIT-C, drinking harms experienced in the last 4 weeks, and unplanned drunkenness in the last 4 weeks. Results: Heavy and non-drinker prototype similarity predicted AUDIT-C, drinking harms and unplanned drunkenness when controlling for past behaviour and reasoned action pathway constructs. Intentions and willingness both mediated the relationship between prototype perceptions and AUDIT-C. Conclusion: This study supports the use of the PWM in the prediction of AUDIT-C, drinking harms and unplanned drinking in a UK sample. Prototype perceptions influenced behaviour via both reasoned and reactive cognitions. Targeting similarity to heavy and non-drinker prototypes should be the focus of future interventions in this population.     

Socio-economic status and the developing brain in adolescence: A systematic review

Socioeconomic status is associated with differences in social, cognitive, and behavioral outcomes for adolescents. Correspondingly, the period reflects continued dynamic, complex, and adaptive brain development. Research demonstrates associations between the developing adolescent brain and SES; however, such research has not been systematically integrated. We undertook a systematic search of studies and review 21 papers that examined both SES and brain development or functioning as measured during adolescence or young adulthood in nonclinical populations (13–25 years old). Few studies focused on architecture and such findings were varied. The majority of studies focused on functioning with two themes emerging. First, studies demonstrate different activation in regions of interest to cognitive and behavioral tasks relative to SES. Second, when similar neurological activation is evident, they can be related to different behavioral observations relative to SES. There is also evidence of different neurological functioning associated with SES with regard to different conceptualizations and coding of SES. Further, some of the reviewed studies identified potential mediators to the relationship, such as parenting practices, stress, and IQ. Overall, the findings suggest it is important to consider SES and neighborhood context within neuroscience research and practice.     

Romantic relationship commitment and the threat of alternatives on social media

Although previous findings suggest a link between adults' use of social networking sites (SNS) and relationship commitment, research has been lacking. This study of 427 emerging and young adults (aged 18–32 years, 71.20% female) indicated that exposure to alternative partners on SNS was indirectly related to relationship commitment through the pursuing of alternative partners on SNS. The more frequently they were exposed to alternative partners on SNS, the more they engaged in pursuing these alternative partners, which negatively affected their relationship commitment. Furthermore, a positive relation between exposure and romantic comparison to alternative partners was found. Gender did not moderate these relations. The discussion focuses on the implications of the findings for relationship development.     

Perceived control effects on religiosity and quality of life among young adults

The study investigated the mediating role of perceived control in the association between religiosity and quality of life among young adults in south-west Nigeria. Data were collected from a sample of 1 050 young adults (mean age = 29.8, SD = 4.61; female = 38.7%). Regression analysis was utilised to predict quality of life from religiosity, partialling out perceived control. Findings suggest internal religiosity to predict an environmental domain of quality of life through perceived control. Perceived constraints appear to explain the association between internal religiosity and the environmental domain of quality of life.     

Identity Status,Gender, and Social Comparison Among Young Adults

The aim of this study was to investigate identity status globally and across identity domains among young Swedish adult women and men. Also, potential differences in social comparison among identity statuses were evaluated. The results showed that most of the 124 participants (50% women, M_age 33.29 years) were assigned to an achieved global identity and had made identity-defining commitments across domains. Gender differences in identity status were found in the occupational and parenthood domains. In addition, differences in social comparison orientation were found only in the parenthood domain, whereas those assigned to moratorium scored higher in social comparison than did those assigned to foreclosure and diffusion. These results bring important knowledge to our understanding of identity during young adulthood.
