Relations among chronic peer group rejection, maladaptive behavioral dispositions, and early adolescents' peer perceptions.

Adolescents' perceptions of peers' relational characteristics (e.g., support, trustworthiness) were examined for subtypes of youth who evidenced chronic maladaptive behavior, chronic peer group rejection, or combinations of these risk factors.

The effect of electrical stimulation on corticospinal excitability is dependent on application duration: a same subject pre-post test design.

Background: In humans, corticospinal excitability is known to increase following motor electrical stimulation (ES) designed to mimic a voluntary contraction. However, whether the effect is equivalent with different application durations and whether similar effects are apparent for short and long applications is unknown. The aim of this study was to investigate whether the duration of peripheral motor ES influenced its effect on corticospinal excitability.

The Child Behavior Scale (CBS) revisited: a longitudinal evaluation of CBS subscales with children, preadolescents, and adolescents.

The Child Behavior Scale (CBS) is a teacher-report instrument that was developed over a decade ago as an alternative to more costly methods for assessing children's behavior and peer relations in school contexts. This investigation was undertaken to clarify how well the CBS achieves its aims with a broader age spectrum of youth (6- to 13-year-olds). Investigative aims were to examine the basic psychometric properties of the CBS and evaluate the construct and criterion-related validity of the CBS's 6 subscales at each of 8 grade levels (Grades 1-8).
