To illuminate individual differences in the development of attention-deficit hyperactivity disorder (ADHD) symptoms in the general population, psychometric measures are needed that can capture general population-level symptom variation reliably, validly, and comparably from childhood through to the transition to adulthood. The ADHD subscale of the…

The Positive and Negative Affect Schedule (PANAS) has been widely used to assess affect expression. Shortened and adolescent versions of the measure have been created, such as the 10-item PANAS for Children (PANAS-C). However, affect expression often involves substantial intraindividual variability, and no research has examined within-person…

In this study, I sought to investigate whether visuospatial working memory (VWM) explains individual differences in reading fluency growth. One hundred and thirty Japanese junior and senior high school students were administered the Mr. Peanut and reversed Corsi tasks, respectively as measures of VWM, followed by three waves of reading fluency…

Some researchers indicate that the transition to high school deflects adolescent developmental trajectories. Others assert that it provides a new possibility for the promotion of adolescents' socioemotional well-being. One critical view missing in such claims is that individual variabilities interact with environmental influences. We employed the…

Using the Jesness Inventory (JI), personality patterns of delinquents were compared with a socially acting-out group and a control group. The Asocial Index was significant across and between all groups with a progressive increase in T scores directly related to delinquent involvement. (Author)

We are delighted to welcome you to the International Psychological Applications Conference and Trends 2014, taking place in Porto, Portugal, from 4 to 6 of April.

This study examined the psychometric properties of a multidimensional measure of prosocial behaviors, the Prosocial Tendencies Measure-Revised (PTM-R), with early and middle adolescents. Results showed adequate reliability and evidence of validity for the PTM-R. Discussion focused on individual differences in prosocial behaviors among early and…

Examined the empirical validity of a model of human motivation as it applies to school success and failure, assessing how indicators of context, self, and action related to measures of risk and resiliency. Subjects were 10- to 16-year-old African American youth in 3 independent samples. Found that parental engagement predicted school performance…
