Studying cross-cultural differences in temperament in toddlerhood: United States of America (US) and Italy

Cross-cultural differences between matched samples (N = 306) of Italian and US toddlers were evaluated. Italian toddlers received higher scores on cuddliness, impulsivity, low intensity pleasure, perceptual sensitivity and positive anticipation, whereas US toddlers were higher on frustration, high-intensity pleasure, inhibitory control, shyness, and soothability.     

Developmental analyses of individual differences in intelligence: Comments on Demetriou et al. (2013)

In this commentary, I mention strengths of the work reported by Demetriou et al. (2013), including sophisticated methods, a powerful integrative theory, and provocative findings. I also suggest ways in which this line of work could be extended, including extending the developmental trajectory, moving beyond tests and tasks, and exploring the full richness of individual variations.     

Adult attachment avoidance and automatic affective response to sad facial expressions

The present work represents the first study to investigate the relationship between adult attachment avoidance and anxiety and automatic affective responses to basic facial emotions. Subliminal affective priming methods allowed for the assessment of unconscious affective reactions. An affective priming task using masked sad and happy faces, both of which are approach‐related facial expressions, was administered to 30 healthy volunteers. Participants also completed the Relationship Scales Questionnaire and measures of anxiety and depression. Attachment avoidance was negatively associated with affective priming due to sad (but not happy) facial expressions. This association occurred independently of attachment anxiety, depressivity, and trait anxiety. Attachment anxiety was not correlated with priming due to sad or happy facial expressions. The present results are consistent with the assumption that attachment avoidance moderates automatic affective reaction to sad faces. Our data indicate that avoidant attachment is related to a low automatic affective responsivity to sad facial expressions.     

Cultural,contextual, and gender differences in peer talk: A comparative study

Tulviste, T., Mizera, L., De Geer, B. & Tryggvason, M.‐T. (2010). Cultural, contextual, and gender differences in peer talk: A comparative study. Scandinavian Journal of Psychology. The study focused on cultural, contextual, and gender differences in children’s peer talk. Same‐sex dyads of Estonian (n = 38), Finnish (n = 38), and Swedish (n = 34) preschool age children were videotaped during unstructured and structured play settings. We found only one gender difference in children’s talkativeness and in the use of regulatory speech: during free play, Swedish boys used more imperatives per directives than Swedish girls. At the same time there were significant cultural and contextual differences. Estonian children were most directive and Swedish children were least directive. Finnish children were less directive than Estonian children but more directive than Swedish children. It was concluded that cultural and contextual factors strongly influence the likelihood, extent, and nature of gender differences in peer talk.     

Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women

The aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

Evaluating the contribution of different item features to the effect size of the gender difference in three-dimensional mental rotation using automatic item generation

In complex three-dimensional mental rotation tasks males have been reported to score up to one standard deviation higher than females. However, this effect size estimate could be compromised by the presence of gender bias at the item level, which calls the validity of purely quantitative performance comparisons into question. We hypothesized that the effect of gender bias at the level of distinct item design features could lead to either an over- or underestimation of reported effect sizes of the gender difference in three-dimensional mental rotation. Using automatic item generation we conducted a series of psychometric experiments in which we independently manipulated one out of four different item design features that have exhibited a gender bias in the previous studies (study 1). This was done in a between-subjects design. The results indicated that gender bias caused by item design features linked to the perceptual stadium of mental rotation led to an overestimation of the effect size of the gender difference while item design features associated with the encoding and transformational stadium resulted in an underestimation of the effect size of the gender difference. In study 2 we tested the hypothesis that the gender difference still remains while controlling for the item design features causing gender bias. The results suggest that a significant portion of the gender difference may be attributable to perceptual and encoding processes involved in mental rotation.     

Organized Community Activity Participation and the Dynamic Roles of Neighborhood Violence and Gender among Latino Adolescents

Relative to their peers, Latino youth are underinvolved in organized community activities (e.g., Boys and Girls Club), and their experiences lack examination. This study employed a neighborhood case‐study approach to examine the experiences of Latino youth in a neighborhood with high levels of violence and their participation in organized community activities. Employing a cluster sampling design (Lohr, Sampling: Design and analysis. Pacific Grove, CA: Nelson Education, 2009), we used quantitative, spatial, and qualitative data to understand adolescents’ participation in organized community activities. Furthermore, to understand how adolescents from the same neighborhood may experience violence differently we examined gender differences. Those who participated in organized community activities witnessed more violence, regardless of gender. General violence (e.g., robberies, shootings) was dispersed throughout the neighborhood, but gender‐specific violence was concentrated along the main street of the neighborhood. In qualitative interviews, adolescents reported this concentration of violence a deterrent to their participation: sexual harassment for girls and gang intimidation for boys. Our findings highlight the unique experiences of youth in violent neighborhoods and the importance of examining differential constraints for those within the same neighborhood.     

Marital Status and Health Beliefs: Different Relations for Men and Women

Although relations between marital status and health have been substantiated, the results of relatively few studies suggest how or why marriage is associated with health. To understand how marriage and health are associated, this study was designed to examine the role of health beliefs. Two thousand two hundred and six (2,206) adults who participated in the New Jersey Family Health Survey provided information about their marital status, proactive health beliefs, and proactive health behaviors. Results indicated that being married (vs. single) was positively associated with men's proactive health beliefs, whereas marriage did not appear to influence women's proactive health beliefs positively. Significant relations between participants' reports of proactive health beliefs and proactive health behaviors were found. Findings are discussed in terms of the importance of understanding the complex nature of associations between social relationships and health.
