The facial stereotypies of adults diagnosed as having mental retardation and tardive dyskinesia were examined through a kinematic analysis of videotaped lip and tongue movements. The high degree of movement variability found suggests that low variability of discrete properties of movement kinematics may not be a defining feature of stereotypies.…

Studied leisure behavior patterns over 3 years during the transition from adolescence to young adulthood with data for 954 participants from the Michigan Study of Adolescent Life Transitions. Leisure pattern stability was the most common pathway into young adulthood. Discusses gender differences. (SLD)

Taking a meta-theoretical perspective, this article presents a critical analytical model through which human knowledge, existence, and behaviour can be understood. The article describes the meta-theoretical model and then explains how this model applies to the evolution of seminal family therapy theories.

In this article, the author describes three major temperament categories of infants and toddlers, and why each calls for particular insights and attention. For infants, the temperaments are cautious, fussy, and easygoing. For toddlers, the three most prevalent temperaments are fearful/shy, irritable/active/fussy, and easy. This paper also contains…

We discuss the relationship between sleep, dreams, and memory, proposing that the content of dreams reflects aspects of memory consolidation taking place during the different stages of sleep. Although we acknowledge the likely involvement of various neuromodulators in these phenomena, we focus on the hormone cortisol, which is known to exert…

Kappa (Cohen, 1960) is a popular agreement statistic used to estimate the accuracy of observers. The response of kappa to differing baserates was examined and methods for estimating the accuracy of observers presented. Results suggest that setting a single value of kappa as "minimally acceptable" (i.e., a criterion value) is not useful in ensuring…

Goal-setting effects on selected performance behaviors of 5 collegiate rugby players were assessed over an entire competitive season using self-generated targets and goal-attainment scaling. Results suggest that goal setting was effective for enhancing task-specific on-field behavior in rugby union. (Contains 1 figure.)

Annual survey data on 776 students from sixth through ninth grade were used to examine the relationships among after-school activities, misbehavior in school, and delinquency. The social development model hypothesizes that antisocial behavior in one developmental time period leads to less involvement in activities and interactions that have…

Despite important clinical and nosological implications, the comorbidity of oppositional defiant disorder (ODD) and generalized anxiety disorder (GAD) has received little attention. A clinic-based sample of 243 boys (ages 6-10 years), their parents, and teachers participated in an evaluation that involved assessments of behavioral, academic, and…

In answering general-information questions, a within-person confidence-accuracy (C-A) correlation is typically observed, suggesting that people can monitor the correctness of their knowledge. However, because the correct answer is generally the consensual answer--the one endorsed by most participants--confidence judgment may actually monitor the…

This study examined posttraumatic stress disorder (PTSD) and comorbid disorders in 70 preschool children (ages 3-6) and their caregivers following Hurricane Katrina. Children's rate of PTSD was 50.0% using age-modified criteria. The rate of PTSD was 62.5% for those who stayed in the city and 43.5% in those who evacuated. Of those with PTSD, 88.6%…

Recent studies have suggested that educational leaders enacting a balance of technical and adaptive leadership have an effect on increasing student achievement. Technical leadership focuses on problem-solving or first-order changes within existing structures and paradigms. Adaptive leadership involves deep or second-order changes that alter…

A plethora of research (McCadden, 1998; Monroe 2005; Skiba, Peterson, & Williams, 2000) on student discipline emphasizes the inequities surrounding the distribution of disciplinary actions taken by schools/school districts in regards to behavior, particularly for African American males. This study provides an in-depth examination of disciplinary…

Fritz Redl (1902-1988) originated the life space model of therapeutic intervention with children who display angry and defiant behavior. His methods were honed by decades of direct work with highly aggressive youth. Redl observed that the same surface behavior could spring from very different underlying problems, thus requiring different…

The behaviours of infants were observed using home videos, in an attempt to identify social difficulties characteristic of infants with autistic disorder. Three groups of infants were analysed: 15 infants who had later been diagnosed with autism, 15 infants who had a developmental or language delay, and 15 typically developing infants. Social…
