The relationship between children's self-reported problems on the Personality Inventory for Youth (PIY) and peer descriptors derived from the Pupil Evaluation Inventory was examined in a regular education sample of 156 children in fourth through eighth grade. The relative contributions of the PIY scales and subscales to the prediction of peer…

The present commentary gives a brief overview of the person-oriented and variable-oriented approaches, how they are commonly used in longitudinal research, and what one should take into consideration before using either approach. In addition to presenting an empirical example on girls' adjustment problems using both approaches, this commentary…

Will reporting subscores provide any additional information than the total score? Is there a method that can be used to provide more trustworthy subscores than observed subscores? These 2 questions are addressed in this study. To answer the 2nd question, 2 subscore estimation methods (i.e., subscore estimated from the observed total score or…

Mother-child relationships characterized by dyadic synchrony, a mutually responsive and interconnected interaction style, have been consistently linked to children's psychosocial adjustment in early childhood, but it is unclear whether such interaction patterns remain conducive to positive outcomes in early adolescence. The aim of the present…

The objectives of this paper are two-fold: to examine first, if the change from positive to negative alcohol and any other substance use status from baseline assessment to the onset of the first session (i.e., pre-treatment phase) occurs in adolescents, that is, Assessment Reactivity (AR); second, whether AR predicts treatment outcome.…

Past studies indicate that students are frequently poor judges of their likely academic performance in the classroom. The difficulty a student faces in accurately predicting performance on a classroom exam may be due to unrealistic optimism or may be due to an inability to self-evaluate academic performance, but the resulting disconnect between…

In a series of three experiments, we investigated the development of children's understanding of the similarities between photographs and their referents. Based on prior work on the development of analogical understanding (e.g. Gentner & Rattermann, 1991), we suggest that the appreciation of this relation involves multiple levels. Photographs…

Studying short-term dynamic processes and change mechanisms in interaction yields important knowledge that contributes to understanding long-term social development of children. In order to get a grip on this short-term dynamics of interaction processes, the authors made a dynamic systems model of dyadic interaction of children during one play…

The current study examines a series of interactions between a prior history of suicidal behavior and cognitions permissive of suicide, and the variables of depression and hopelessness in the relationship with suicidal ideation in two samples of incarcerated offenders. Results indicate that both a prior history of suicidal behavior and cognitions…

In this prospective longitudinal study, the authors examined the relationship between reduced specificity in autobiographical memory retrieval and the development of depression, posttraumatic stress disorder (PTSD), and specific phobia after injury in an assault. Assault survivors (N = 203) completed the Autobiographical Memory Test (J. M. G.…

This study investigated how the face threat mitigation students received from their teachers during feedback influenced their judgments about mentored relationships with their teachers and the supportiveness of the classroom learning environment. Public speaking students (N=345) at three universities completed an online survey about the speech…

The power of scales based on the Psychopathy Checklist (PCL; R. D. Hare, 1980) for prediction of violent behavior is well established. Although evidence suggests that this relationship is chiefly due to the impulsive and antisocial lifestyle component (Factor 2), the predictive power of psychopathy for violence may also reflect the multiplicative…

The set of statistical methods available to developmentalists is continually being expanded, allowing for questions about change over time to be addressed in new, informative ways. Indeed, new developments in methods to model change over time create the possibility for new research questions to be posed. Latent transition analysis, a longitudinal…

S. Ghetti (2008) and M. L. Howe (2008) presented probative ideas for future research that will deepen scientific understanding of developmental reversals on false memory and establish boundary conditions for these counterintuitive patterns. Ghetti extended the purview of current theoretical principles by formulating hypotheses about how…

A simple mixing of a hot- and cold-water stream at a T-junction was investigated. The main objective was to use mass and energy balance equations to predict mass low rates and the temperature of the mixed stream after the T-junction, and then compare these with the measured values. Furthermore, the thermocouple location after the T-junction and…
