This paper addresses a number of key challenges in current subjective well-being (SWB) research: A new wave of studies should take into account that different things may make different people happy, thus going beyond a unitary "happiness formula". Furthermore, empirical results need to be connected to broader theoretical narratives.…

The aim of the present study was to examine to what extent classroom factors (i.e., classroom antibullying attitudes and behavioral norms) contributed to individual bullying, after controlling for individual difference characteristics. Participants were 2,547 early adolescents (M = 13.4 years, SD = 0.63) from 109 middle school classes. Self- and…

Individual differences in strategy use (choice and accuracy) were analyzed. A sample of 362 Grade 6 students solved complex division problems under 2 different conditions. In the choice condition students were allowed to use either a mental or a written strategy. In the subsequent no-choice condition, they were required to use a written strategy.…

Peer nominations are used widely in psychological and sociological research to examine intergroup dynamics, even though this assessment tool suffers from thorny methodological problems: Gender, ethnic, age, and trait compositions vary across subsamples, subjects differ in the number of nominations they make, and the issue of sampling without…

This study identifies grief management strategies that bereaved adults evaluate as more and less helpful, assesses whether the person centeredness of these strategies explains their helpfulness, and determines whether strategy helpfulness varies as a function of demographic, personality, and situational factors. Participants (105 bereaved young…

The study aims to determine critical thinking tendencies among teacher candidates. 720 students from primary school teaching department (Primary School Teaching Programme, Science Teaching Programme and Pre-School Teaching Programme) form the sample of the study. When the gender and age distributions were investigated, 253 candidates are males and…

Toward greater specificity in the prediction of externalizing problems in the context of interparental conflict, interactions between children's parasympathetic and sympathetic nervous system (PNS and SNS) activity were examined as moderators. PNS activity was indexed by respiratory sinus arrhythmia (RSA) and RSA reactivity (RSA-R) to lab…

This study employs an intra-national and cross-national, prospective, and longitudinal design to examine age, gender, region, and country variation in group mean-level continuity and individual-differences stability of emotional availability in child-mother dyads. Altogether, 220 Argentine, Italian, and US American metropolitan and rural residence…

General cognitive ability ("g") does not explain sex differences in academic test performance by the end of compulsory education. Instead, individual differences in specific reasoning abilities, after removing the effects of "g," may contribute to the observed gender gaps. Associations between general or specific cognitive…

In this longitudinal study, we examined whether certain types of stressful events and how individuals respond to these events would explain gender differences in depressive symptoms among adolescents. We hypothesized that certain stressful events would mediate the relationship between gender and depressive symptoms. We also hypothesized that…

The author examined whether independent or peer revision produced a greater number of meaningful revisions between drafts. The study was a single-participant, alternating treatment design. The sample comprised 8 students in a predominately low-SES urban school in the United States. Students of mixed gender and background were in a self-contained,…

This paper presents a new perspective on the transition from early to middle childhood (i.e., human juvenility), investigated in an integrative evolutionary framework. Juvenility is a crucial life history stage, when social learning and interaction with peers become central developmental functions; here it is argued that the "juvenile transition"…

As teachers struggle to meet the needs of a highly diverse student body, technology holds out the promise of a solution. However, first the nature and scope of differences between students has to be identified. This study (n = 1811) takes a comprehensive approach, selecting differences from each stage in the learning process. These were termed…

Research shows that the role of the K-12 principal is a significant factor in school improvement. Principal preparation programs have been criticized for inadequately preparing their graduates for the challenges they must face in K-12 schools. Since higher education faculty members directly impact the success of their programs (Bartlett, 2003),…

The Eurofit Special Test is a battery of motor fitness tests resulting from a 10-year project of the Committee of Experts for Sports Research and is comprised of strength, speed, flexibility, and balance. The purpose of this study was to investigate whether the Eurofit Special was able to distinguish variations in functioning among individuals…
