This paper examines the hypothetically bi-directional relationship which links marijuana consumption and school failure among students. To that end, we propose a simultaneous probability model, which is estimated by using the information provided by the three consecutive waves from the Spanish Surveys on Drug Use in the School Population [(1996,…

The current study investigated the nature of subjective cognitive complaints of older adults in relation to a broad array of individual cognitive functions known to decline with age. A 60-item questionnaire was developed to examine: (1) whether older adults experience problems with these cognitive functions (problems with cognition); (2) the…

Given a growing emphasis on early intervention for children with autism, valid quantitative tools for measuring treatment response are needed. The Social Responsiveness Scale (SRS) is a brief (15-20 minute) quantitative measure of autistic traits in 4-to 18-year-olds, for which a version for 3-year-olds was recently developed. We obtained serial…

The purpose of this investigation was to examine the force production patterns using perceived stimulus cues from 10% to 90% of maximal force. In Experiment 1, 54 men (age: 19-34 years) and 53 women (age: 18-37 years) performed leg extensions on a dynamometer at a speed of 60 degrees/s. Participants produced actual forces perceived to be 10-90% of…

Personality traits, self-perceptions, beliefs, and feelings that accompany the Imposter Phenomenon (IP) have been identified in adults but little research with adolescents has been reported. The present research describes data from a sample of 11th and 12th graders in order to examine predictors of IP among adolescents. The participants completed…

The role of siblings ("N" = 50) in the display of physical and relational aggression among peers during early childhood was explored. Specifically, sibling pairs' rates of physical and relational aggression were assessed in their independent social contexts. Findings indicated low to moderate levels of intercorrelation between physical and…

Purpose: In the light of the growing emphasis on independent learning and non-technical skills in education and employment, the study aims to examine the relevance of learning style to student self-assessment skill. Design/methodology/approach: A sample of first-year undergraduate students was asked to provide self-assessed marks for their…

This article used multitrait-multimethod methodology and covariance modeling for an investigation of the presence and correlates of method effects associated with negatively worded items on the Rosenberg Self-Esteem (RSE) scale (Rosenberg, 1989) using a sample of 757 adults. Results showed that method effects associated with negative item phrasing…

Event-related potentials were measured as subjects read sentences presented word by word. A small N400 and a robust P600 effect were elicited by verbs that assigned the thematic role of Agent to their preceding noun-phrase argument when this argument was inanimate in nature. The amplitude of the P600, but not the N400, was modulated by the…

The role of maternal chronological age in prenatal and perinatal history, social support, and parenting practices of new mothers (N=335) was examined. Primiparas of 5-month-old infants ranged in age from 13 to 42 years. Age effects were zero, linear, and nonlinear. Nonlinear age effects were significantly associated up to a certain age with little…

This study examined relationship aggression reporting concordance among 303 men with alcohol use disorders and their female partners enrolled in couples-based alcohol abuse treatment. Agreement for physical and psychological aggression was generally consistent with, or higher than, concordance rates reported among other populations. Men's…

This study introduces potential risk factors for victimization and perpetration of sexual harassment among teens not previously studied. The first set of analyses compared histories of perpetration and victimization by gender, as well as the relationship between risk factors and perpetration or victimization. For girls (r = 0.544) and boys (r =…

Cognitive diagnosis models are constrained (multiple classification) latent class models that characterize the relationship of questionnaire responses to a set of dichotomous latent variables. Having emanated from educational measurement, several aspects of such models seem well suited to use in psychological assessment and diagnosis. This article…

The association between corporal punishment and children's emotional and behavioral functioning was studied in a sample of 98 non-referred children with a mean age of 12.35 (SD=1.72) recruited from two school systems in the southeastern United States. Children were divided into those who had experienced no corporal punishment over approximately a…

In two studies, Study 1 and Study 2, we examine whether attitudes toward people with intellectual disabilities, like sexism and racism, consist of two forms--a classical and a modern, where the classical is overt and blatant and the modern is more subtle and covert. Self-report scales tapping these two forms were developed in Study 1. Based on…
