Background: Roifman syndrome (OMIM 300258) is a multi-system disorder with a physical phenotype that includes B-cell immunodeficiency, intra-uterine and postnatal growth retardation, spondyloepiphyseal dysplasia, retinal dystrophy and characteristic facial dysmorphism. So far, six cases, all boys, have been reported in the literature. Roifman…

As cognitive architectures move to account for increasingly complex real-world tasks, one of the most pressing challenges involves understanding and modeling human multitasking. Although a number of existing models now perform multitasking in real-world scenarios, these models typically employ customized executives that schedule tasks for the…

The behavior-based approach to managing occupational risk and preventing workplace injuries is reviewed. Unlike the typical top-down control approach to industrial safety, behavior-based safety (BBS) provides tools and procedures workers can use to take personal control of occupational risks. Strategies the author and his colleagues have been…

The relationship between two classes of retrieval process--retrieval orientation and retrieval effort--was investigated using electrophysiological (ERP) and behavioural measures. ERPs were recorded during retrieval phases of exclusion tasks in which participants focused on retrieval of either phonological or semantic associates that were generated…

Research into behavior problems among individuals with mental retardation has been well developed. However, few studies have addressed the effect of multiple problem behaviors on social skills. In the present study, the authors examined the relationship between two problem behaviors, stereotypy and self-injury, and social skills among individuals…

Background: Recent research has shown that the range of repetitive behaviour seen in individuals with Prader-Willi syndrome (PWS) extends beyond food-related behaviour. Methods: The presence and intensity of repetitive, rigid and routinized behaviour in children with PWS was compared with that seen in children with another neurodevelopmental…

This study examined the sexual messages depicted in music videos aired on MTV, MTV2, BET, and GAC from August 2, 2004 to August 15, 2004. One-hour segments of music videos were taped daily for two weeks. Depictions of sexual attire and sexual behavior were analyzed via a four-page coding sheet (interrater-reliability = 0.93). Results indicated…

As computer applications are added to social work, educators are increasingly likely to encounter computer anxiety. This form of anxiety has been well-documented in the literature, including warnings that students attracted to fields that are "people professions" such as social work may be especially prone to problems. This qualitative study used…

We examine relations of values and intelligence to overt behavior in a field study of clients in career counseling (N = 365). Eleven counselors reported their clients' independence, activity and insightfulness behaviors. As predicted, both values and intelligence correlated substantially with particular behaviors. Activity and independence…

Background: Autism spectrum disorder (ASD) includes symptoms that vary in severity and frequency between children. Consequently, multiple psychometric assessment procedures are recommended to detect an ASD, including scales which asses the presence and nature of ASD-related behaviour. However, to date, few studies have examined the relative and…

In 3 studies, the authors developed and began to validate a measure of the propensity to act rashly in response to positive affective states (positive urgency). In Study 1, they developed a content-valid 14-item scale, showed that the measure was unidimensional, and showed that positive urgency was distinct from impulsivity-like constructs…

It is important to understand causes and consequences of procrastination that appear common among general and academic populations. Procrastination affects people in various domains of life such as academic, professional, social relationships, and finance management. A person with high procrastination may lose his/her work, drop out from school,…

This study analysed the effects of the nonverbal behaviour of an examiner on low and high achievers' psychometric performances. The examiner, who was blind to children's achievement level, varied the nonverbal style she adopted when giving instructions. As expected, a warm style led children to score higher than a neutral one. Moreover, warmth…

The purpose of this study is to examine the underlying construct of overexcitabilities (OEs) and to identify individual- and family-level factors that may explain gifted students' patterns of OEs. Data are collected from a convenience sample of identified gifted students (N = 143) and their parents (N = 161) using a Likert-type questionnaire, the…

Research in the development of teacher cognition and teaching performance in K-12 classrooms has identified consistent challenges and patterns of behavior that are congruent with the predictions of dual-process models of cognition. However, cognitive models of information processing are not often used to synthesize these results. This article…
