Longitudinal associations between impulsivity and lie-telling in childhood and adolescence

Lie-telling and impulsivity levels peak during late childhood to early adolescence and have been suggested to be related. Heightened impulsivity may lead adolescents to lie in favor of short-term benefits without consideration for the potential consequences of deception. The present study assessed longitudinal relations between self-reported impulsivity and lie-telling frequency. Participants from a large-scale longitudinal study (N = 1148; M_age = 11.55, SD = 1.69, 9–15 years at Time 1) reported on their impulsivity (Barratt Impulsiveness Scale) and their frequency of lie-telling to parents, to teachers, to friends, and about cheating across two time points 1 year apart. Cross-lagged path analysis revealed greater impulsivity was associated with more frequent lie-telling to parents, friends, and teachers, and about cheating over time. Our findings demonstrate the role of impulsivity in the development of lie-telling behaviors.

Research Highlights

• Impulsivity predicts lying across time in multiple contexts (to parents, friends, teachers, and about cheating).
• Previous research has demonstrated the role of top-down influences on lie-telling, but the current study suggests that bottom-up processes are also influential.

     

Stereotypes in the classroom's air: Classroom racial stereotype endorsement,classroom engagement,and STEM achievement among Black and White American adolescents

Initiatives promoting diversity, equity, and inclusion in predominantly White contexts, including STEM fields, have primarily relied on approaches to increase the representation of minoritized individuals. However, an increase in the representation of minoritized individuals is only one step of the process, as the present study suggests that explicit beliefs about particular racial groups’ abilities also matter. The present article examined whether classroom racial stereotype endorsement about science and math disadvantaged Black American adolescents relative to their White American peers. Across two longitudinal studies with 533 and 1,189 adolescents (N-adolescents = 1722; N-classrooms = 86; 45% Black American, 55% White American; 51% females; M-age = 13–14), classroom pro-White/anti-Black stereotype endorsement in the fall term predicted better science and math achievement scores for White American adolescents and lower science and math achievement scores for Black American adolescents at the end of the academic year. Student- and teacher-reported student engagement in science and math classrooms mediated the longitudinal relations between classroom pro-White/anti-Black stereotype endorsement and students’ achievement scores. Results suggest that classrooms may be important conduits for communicating racial stereotypes that create racially hostile STEM learning environments.

Research Highlights

• Using a longitudinal sample of 1722 adolescents enrolled in 86 classrooms, the present study examined the consequences of classroom racial stereotype endorsement during adolescence.
• White American adolescents demonstrated favorable achievement scores in science and math when their classmates endorsed traditional, or pro-White/anti-Black, stereotypes.
• Black American adolescents showed worse achievement scores in science and math when their classmates endorsed pro-White/anti-Black stereotypes.
• Classroom engagement mediated the longitudinal relations between classroom pro-White/anti-Black stereotype endorsement and achievement scores for both Black and White American adolescents.

     

The Network Constellation of Personality and Substance Use: Evolution from Early to Late Adolescence

There is a well-established link between substance use and four personality traits of anxiety–sensitivity, hopelessness, impulsivity, and sensation-seeking. However, construct-level models of personality may conceal indicator-level personality–outcome associations. The current study aims to investigate evolution of the network constellation of personality and cannabis/alcohol use from early to late adolescence. Data comes from the longitudinal Co-Venture cohort (N = 3800). Personality indicators, measured by Substance Use Risk Profile Scale (SURPS) items, and the frequency of cannabis/alcohol use were assessed at four consecutive years (13–17 years old). Network constellations of the SURPS items and cannabis/alcohol use were estimated using Bayesian Gaussian graphical models at four time points. Results highlighted the age-specific associations between personality indicators and substance use. The positive role of the sensation-seeking trait (e.g. attitude towards transgression) was constant, whereas the positive role of hopelessness indicators (e.g. not being enthusiastic about future) and the negative role of anxiety–sensitivity indicators (e.g. fear of having unusual body sensations) were more prominent at early adolescence. The current study provides a novel perspective on the network structure of personality and substance use in adolescence and suggests substance-specific and age-adjusted targets in intervention efforts. © 2020 European Association of Personality Psychology     

Relationship between Family Functioning and Possible Selves in Adolescents from Argentina

Abstract

The goal of this study was to analyze the relationship between different family functioning types and the content, valence, and structure of adolescents’ possible selves (PSs). Participants were adolescents (n?=?392) of both genders (female = 54.9%) from private and catholic high schools in the city of Buenos Aires, Argentina (age, M?=?14.92, SD?=?1.52). We performed a cluster analysis to explore family functioning profiles in terms of communication with parents, promotion of challenges, family cohesion, and flexibility. In order to study family functioning type and PSs content association, we performed a chi-squared test. To study family functioning type differences in PSs valence and structure we conducted a one-way MANOVA. The chi-squared test indicated that there was no significant association between family functioning type and adolescents’ PSs spontaneous content. On the other hand, the MANOVA revealed the existence of significant differences in PSs valence between each type of family functioning group. In regard to the structure of PSs, there were no significant differences between family functioning types. In conclusion, adolescents who perceived positive family functioning have more positive PSs. Family functioning type was not related to PSs content and structure.
