Prosocial tendencies predict friendship quality, but not for popular children

Is prosocial behavior a prerequisite for having good-quality friendships? This study (N = 477, mean age = 12.2 years) examined whether the link between children’s prosocial tendencies and their perceived friendship quality was dependent on children’s level of popularity in the peer group. Children’s prosocial tendencies were assessed both as observed behavior in a standardized setting and as a self-reported predisposition to act in prosocial ways. Across measures, the results showed that prosocial tendencies are associated with higher perceived friendship quality among nonpopular children (i.e., children holding average or lower levels of popularity), but not among popular children. Thus, even if they lack prosocial qualities, popular children are still able to hold good-quality friendships. Popular children may have other compensating characteristics, such as popularity by association, that make them attractive for peers to be friends with.     

Height preferences in humans may not be universal: Evidence from the Datoga people of Tanzania

Many studies in Western societies have shown that women prefer relatively taller men as potential partners, whereas men prefer women who are slightly shorter than themselves. Here, we discuss possible limitations of previous results within the context of the stimuli used (i.e., differences in the perceived body size of female silhouettes). Our results show that, at least in a Polish sample (N = 231), modified stimuli did not essentially change the observed male-taller preferences. In contrast, we report height preferences in a traditional ethnic group, the Datoga people from Tanzania (N = 107), in which men and women preferred extreme sexual dimorphism in stature (SDS) sets (i.e., men and women chose women much taller or much shorter than themselves). Thus, our data do not accord with the suggestion of a universal preference for taller men, but rather suggests that height preferences may be influenced by cultural, environmental, and ecological conditions.     

Remembering kinds: new evidence that categories are privileged in children's thinking

What are the representations and learning mechanisms that underlie conceptual development? The present research provides evidence in favor of the claim that this process is guided by an early-emerging predisposition to think and learn about abstract kinds. Specifically, three studies (N = 192) demonstrated that 4- to 7-year-old children have better recall for novel information about kinds (e.g., that dogs catch a bug called “fep”) than for similar information about individuals (e.g., that a particular dog catches a bug called “fep”). By showing that children are particularly likely to retain information about kinds, this work not only provides a first empirical demonstration of a phenomenon that may be key to conceptual development but also makes it apparent that young children’s thinking is suffused with abstractions rather than being perceptually-based and concrete.     

A cross-sectional investigation of autogenous and reactive obsessions and associated cognitive and symptom correlates in China

Categorizing clinical obsessions as either autogenous or reactive, a model that has been supported by several studies, may represent a parsimonious approach to characterizing individuals with obsessive-compulsive disorder (OCD). However, most published studies on autogenous and reactive obsessions have been carried out with participants in highly developed nations (e.g., United States, Australia). No studies have been carried out in less developed countries, such as China. It was hypothesized that the nature of autogenous and reactive obsessions and their correlates would generalize to China. This cross-sectional study incorporated three groups from China: a college student sample (N = 1,701), a clinical sample of patients with OCD (N = 158), and a clinical control group of patients with anxiety disorder other than OCD (N = 88). Confirmatory factor analysis provided support for the autogenous and reactive model of obsessions in a Chinese sample. The results also showed that autogenous and reactive obsessions demonstrated a pattern of associations with cognitive and symptom correlates (e.g., obsessive beliefs, traditional OCD subtype themes) that were comparable to those found in previous research. The current study supports the autogenous and reactive obsessions model of OCD and its correlates in China, providing additional evidence for the cultural invariance of the model.     

Dorian Gray without his portrait: Psychological,social, and physical health costs associated with the Dark Triad

We examined how the Dark Triad (i.e., narcissism, psychopathy, and Machiavellianism) traits—as different social strategies—were associated with various health outcomes. In samples of American undergraduates (N = 1389), Australian high school students (N = 2023), and British undergraduates (N = 280), we examined the physical, social, and psychological costs associated with the Dark Triad traits. Narcissism was linked to few mental and physical ailments, suggesting it may provide a social buffer from negative health outcomes (Studies 1 and 2). Psychopathy (Studies 1 and 2) and Machiavellianism (Study 2) were linked to a number of psychological and physical health conditions. In addition, psychopathy was related to diminished life expectancy, whereas narcissism was related to enhanced life expectancy (Study 3). Our findings provide evidence that each of these personality traits is linked to various psychosocial tradeoffs and different methods of coping with stress and adaptive problems.     

The young and the restless: Examining the relationships between age,emerging adulthood variables,and the Dark Triad

The Dark Triad is a set of correlated personality variables (i.e., narcissism, psychopathy, and Machiavellianism) that are related to myriad behaviors. Myriad studies have been conducted to test the relations between the Dark Triad and other personality variables (e.g., the Big 5); however, the developmental correlates have been understudied. In the current study, we examined how markers of emerging adulthood and age predict the Dark Triad traits using a cross-sectional design. Participants (N = 442) of varying ages (M age = 32.99, range = 18–74) completed Dark Triad measures and a validated questionnaire used to assess the degree to which participants believe they have successfully navigated through various facets of emerging adulthood. Emerging adulthood facets (e.g., negativity, other-focused, and feeling in-between) correlated with several Dark Triad traits. Additionally, several emerging adulthood facets mediated the relation between age and the Dark Triad traits; i.e., older participants were lower on the Dark Triad traits because of the successful transition through emerging adulthood. Results are discussed in terms of the Theory of Emerging Adulthood (Arnett, 2000).     

Preparing for uncertain careers: How youth deal with growing occupational uncertainties before the education-to-work transition

Recent changes in labor market and working conditions have rendered youth's education-to-work transitions and career prospects more uncertain. This study investigated how youth, while still in education or training, deal with perceived growing occupational uncertainties in terms of goal engagement (i.e., investing active effort in goal pursuit; surmounting obstacles) and goal disengagement (i.e., distancing from unattainable goals; protecting the self against failure experiences). Analyses with two closely matched samples of youth aged 16–25 years from Germany (N = 529) and Poland (N = 530) revealed high levels of goal engagement and a clear preference of engagement over disengagement. Whereas levels of engagement were comparable across countries, disengagement was considerably higher in Polish youth. Regarding the sources of individual differences in engagement and disengagement, sociodemographic factors had very limited effects in both countries. Compared to sociodemographic factors, the level of perceived growing occupational uncertainties, and especially youth's primary and secondary appraisals thereof, were more strongly and consistently associated with engagement and disengagement, especially in Germany, pointing to the prominence of perceptions and appraisals in shaping youth's responses to growing occupational uncertainties. We offer cultural and economic explanations for these findings and discuss implications for interventions aimed at fostering youth's engagement in preparing for their future careers under today's uncertain conditions.     

Attitude,perceived behavioral control,and intention to adopt risky behaviors

The theory of planned behavior (TPB, Ajzen, 1985) has proved its efficiency in predicting different behaviors among road users (Sheeran & Orbell, 2000). The present study examined the TPB factors explaining risk taking among vulnerable road users (e.g., cyclists). We presumed that attitude, social norms, and perceived behavioral control (PBC) would predict cyclists’ intention to adopt a risky behavior in two traffic contexts considered as risk-conducive (i.e., run the red-light, turn left).Participants (N = 224, M_age = 23.34) filled in an online scenario-based questionnaire describing two traffic situations conducive to risk taking and including measures for cyclists’ intentions to adopt risky behaviors in these specific contexts, TPB factors, and self-perceived efficacy.TPB factors explained 49% and 65% of the variance in the intention to cross the red light, respectively the intention to turn left, with positive attitude and high PBC as the best predictors. Implications of the results were discussed.     

The impact of object type on the spatial analogies in Korean preschoolers

We tested young children’s spatial reasoning in a match-to-sample task, manipulating the objects in the task (abstract geometric shapes, line drawings of realistic objects, or both). Korean 4- and 5-year-old children (N = 161) generalized the target spatial configuration (i.e., on, in, above) more easily when the sample used geometric shapes and the choices used realistic objects than the reverse (i.e., realistic-object sample to geometric-shape choices). With within-type stimuli (i.e., sample and choices were both geometric shapes or both realistic objects), 5-year-old, but not 4-year-old, children generalized the spatial relations more easily with geometric shapes than realistic objects. In addition, children who knew more locative terms (e.g., “in”, “on”) performed better on the task, suggesting a link to children’s spatial vocabulary. The results demonstrate an advantage of geometric shapes over realistic objects in facilitating young children’s performance on a match-to-sample spatial reasoning task.     

Equivalency and reliability of vectors of g-loadings across different methods of estimation and sample sizes

We examine the variability in g-loadings with particular focus on the differential stability (i.e., rank order inconsistencies) of the vector of loadings due to sample size and method of estimation. Our results, based on 1600 factor-analyses, show that different methods of estimation require different sample sizes to achieve the same level of stability in loadings. However, all methods examined yielded reliable vectors when sample sizes of N = 400 were used. Some methods yielded reliable vectors with sample sizes of N = 200. Such results provide guidelines for choosing an appropriate sample size when g-loadings are of interest.     

Competition,autonomy, and prestige: Mechanisms through which the Dark Triad predict job satisfaction

Organizational researchers increasingly recognize the need to consider the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) when explaining undesirable work outcomes (e.g., counterproductive behaviors). However, little research has focused on the motivations of those who actually hold the traits. In this study (N = 361) we examined how the Dark Triad traits predispose individuals to perceive situations as competitive, prestigious, and comprised of restrictions (i.e., autonomy) which differentially predict job satisfaction. Individuals high on psychopathy and Machiavellianism perceived their workplaces as competitive, whereas individuals high on narcissism perceived their workplaces as prestigious and with fewer restrictions. Sex differences in perceptions were fully mediated by psychopathy and Machiavellianism. We discuss our results from an Evolutionary Industrial/Organization Psychology framework.     

Less is not always more: The case of the 36-item short form of the Zimbardo Time Perspective Inventory

Recently, a shortened version of the Zimbardo Time Perspective Inventory (ZPTI; Zimbardo & Boyd, 1999) was proposed as a “gold standard” (Sircova et al., 2014, p. 9). In this study, we examined the internal consistency and structural validity of this version of the ZPTI in samples of adolescents from the United Kingdom (N = 913) and the United States (N = 815), and adults from Australia (N = 667). Results provided support for the internal consistency of ZPTI scores, but structural validity analyses indicated poor fit and numerous problematic items. The findings call into question the use of scores on this shortened version of the ZTPI.     

Neurophysiological marker of inhibition distinguishes language groups on a non-linguistic executive function test

Successful interaction with the environment depends on flexible behaviors which require shifting attention, inhibiting primed responses, ignoring distracting information, and withholding motor responses. These abilities, termed executive function (EF), are believed to be mediated by inhibitory processes in the frontal lobes. Superior performance on EF tests (i.e., faster reaction times (RT), and fewer errors) has been shown in bilinguals compared to monolingual speakers. However, findings are inconsistent, and no study has directly linked this bilingual advantage to frontal lobe inhibitory processes. To clarify this uncertainty, we concomitantly tested neural inhibitory processes and behavioral responses on an EF test in bilinguals and monolinguals. Specifically, we compared English monolinguals (N = 15) to Spanish/English bilinguals (N = 13) on event-related brain potentials (ERP) during a non-linguistic, auditory Go/NoGo task, a task linked to non-motor, cognitive inhibition in monolinguals. Participants responded with a button press on trials in which target tone-pairs (Go trials) were presented and withheld their responses on non-target trials (NoGo trials). Results revealed significantly greater inhibition (i.e., greater mean N2 amplitude) in bilinguals compared to monolinguals during NoGo trials even though both groups performed the task equally well (i.e., withheld a motor response). On Go trials where participants pressed a response button, neither ERPs nor RT distinguished the groups. Additionally, scores on a second language proficiency test (i.e., English in our bilingual group) were positively correlated with N2 amplitude. These findings are the first to directly link this bilingual advantage to a neural correlate of inhibition and to reveal that inhibition in bilinguals is moderated by second language proficiency. Results are discussed in the context of plasticity, and we propose that evaluating bilinguals at varying levels of second-language proficiency may serve as a model of human neuroplasticity.     

Psychosocial correlates of frequent indoor tanning among adolescent boys

The aim of the current study was to assess psychosocial correlates (i.e., perceived weight, weight control strategies, substance use, and victimization) of frequent indoor tanning in adolescent boys—a group at high risk for developing skin cancer. Participants (N = 7,907) were drawn from a nationally representative sample of adolescent boys attending high school in the United States. Binary logistic regression revealed that extreme weight control strategies, particularly steroid use (odds ratio = 3.67) and compensatory vomiting (odds ratio = 2.34), along with substance use and victimization, were significantly related to frequent indoor tanning. These results highlight the role of appearance-changing, and health-risk behaviors in the context of frequent indoor tanning. Skin cancer prevention interventions may benefit from adopting approaches that integrate the treatment of body dissatisfaction and subsequent maladaptive behaviors.     

Competence with fractions predicts gains in mathematics achievement

Competence with fractions predicts later mathematics achievement, but the codevelopmental pattern between fractions knowledge and mathematics achievement is not well understood. We assessed this codevelopment through examination of the cross-lagged relation between a measure of conceptual knowledge of fractions and mathematics achievement in sixth and seventh grades (N = 212). The cross-lagged effects indicated that performance on the sixth grade fractions concepts measure predicted 1-year gains in mathematics achievement (ß = .14, p < .01), controlling for the central executive component of working memory and intelligence, but sixth grade mathematics achievement did not predict gains on the fractions concepts measure (ß = .03, p > .50). In a follow-up assessment, we demonstrated that measures of fluency with computational fractions significantly predicted seventh grade mathematics achievement above and beyond the influence of fluency in computational whole number arithmetic, performance on number fluency and number line tasks, central executive span, and intelligence. Results provide empirical support for the hypothesis that competence with fractions underlies, in part, subsequent gains in mathematics achievement.     

Teacher–child relationships and behavioral adjustment: Transactional links for preschool boys at risk

In this short-term longitudinal study, transactional links between teacher–child relationships and behavioral adjustment were investigated in a sample of preschool boys (N = 175) at risk for developing externalizing problems. Teachers (N = 175) reported about the quality of the teacher–child relationship (i.e., Closeness, Conflict, and Dependency) and about children's behavioral adjustment (i.e., Externalizing Behavior, Internalizing Behavior, and Prosocial Behavior) at three occasions within one school year. Cross-lagged path-analytic models showed positive bidirectional associations between Conflict and both Externalizing and Internalizing Behavior from Time 1 to Time 2, but not from Time 2 to Time 3. In addition, there was a transactional sequence with more Conflict at Time 1 leading to less Prosocial Behavior at Time 2 which, in turn, predicted more Conflict at Time 3. Closeness was reciprocally and positively related to Prosocial Behavior over time, and was positively and unidirectionally predicted by Internalizing Behavior. Dependency showed positive reciprocal links with Internalizing Behavior over time, and negatively and unidirectionally predicted Prosocial Behavior. These findings suggest that interventions may be most effective if they adjust their focus and strategy depending on children's specific behavioral and relational needs.     

Anxieties about aging and death and psychological distress: The protective role of emotional complexity

Death and aging anxieties are related to higher psychological distress, but no study has examined whether these relationships are moderated by emotional complexity, an important indicator of adaptive emotional regulation among older adults. Participants (N = 188; mean age = 57; range = 29–100) rated their death and aging anxieties, general psychological distress, and reported their emotions on a daily basis over 14 days. Results showed that emotional complexity moderated the relationship between each of the two anxieties and psychological distress (i.e., the positive relationship between the two anxieties and psychological distress existed only among subjects with low emotional complexity). The findings suggest that emotional complexity buffers against psychological distress, and can be further explored as a facilitating mechanism in protecting against the negative mental health effects of aging and death anxieties.     

Personality attributes that predict cadet performance at West Point

Using data from the United States Military Academy at West Point (N = 1102 and N = 1049) from two successive years, we examined psychological measures of cadets and the correlations of those measures with consequential outcomes such as cadet performance and leadership potential. We examined four broad intelligences, two of which were thing-focused (spatial and mathematical) and two people-focused (verbal and personal intelligences) and their predictions to thing- and people-centered courses (e.g., chemistry versus psychology). We found support for a thing-people differential in reasoning. The broad intelligences and the Big Five personality traits also predicted academic and other performance criteria at consequential levels.     

Pathology,pseudopathology, and the Dark Triad of personality

The Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) have traditionally been viewed as undesirable and pathological. In contrast, an evolutionary perspective suggests that traits like these might be pseudopathologies; traits that society actively dislikes in that they pose a threat to the collective good. We examined (N = 290) how the Dark Triad traits related to intrapersonal (i.e., behavioral dysfunction), quasibehavioral (i.e., reactive and proactive aggression), and interpersonal (i.e., communal and exchange orientation) factors. Psychopathy predicted high rates of behavioral dysregulation and both forms of aggression. Psychopathy and Machiavellianism showed an aversion towards communalism but an exchange orientation to social relationships. Lastly, individual differences in the Dark Triad traits accounted for part (5–22%) of the sex differences in social strategies and aggression. The theoretical implications of these findings are discussed in, and in support of, an evolutionary paradigm.
