Parents and professionals working with children with disabilities are urged to be alert to discrepancies between a child's usual behavior and capabilities and those exhibited during a formal testing or evaluation session. (DB)

Examines the effects of literacy-enriched play settings on preschoolers' literacy behaviors in spontaneous free play. Finds differences in frequency, duration, and complexity of literacy demonstrations in play. Finds that children incorporated literacy objects in more diverse and functional ways than children playing in a normal physical…

Analyzed relational control behaviors and interaction patterns of 51 couples representing marital life span. Identified three distinct phases of development: short-term couples relied heavily on "equivalence" acts; intermediate couples were more likely to "structure the conversation" but avoided competing for control; and long-term couples relied…

Compared conflictual marital interactions of 17 physically aggressive, 15 verbally aggressive, 18 withdrawing, and 15 low-conflict couples to describe behavior patterns characteristic of couples who report different marital conflict styles. Physically aggressive couples were characterized by reciprocity of hostile affect and by rigid, contingent…

The variability of stereotypic body-rocking motions of eight adults with severe/profound mental retardation was examined through kinematic analysis and compared to a matched nonretarded group of adults. Inter- and intra-individual variability was, on average, higher for the individuals with mental retardation. Results suggest that low variability…

Investigates the concept of animacy of 9- and 12-month-old infants by exposing them to autonomous motion with animate and inanimate objects in a series of three experiments. Three experiments were carried out. Results indicated that infants discriminate animate from inanimate objects on the basis of motion cues by the age of nine months. (MOK)

Rett syndrome is a neuro-developmental disorder that almost exclusively affects females. In addition to neuro-developmental regression and loss of hand skills, apraxia, deceleration of head growth, and increasing spasticity and scoliosis, a number of behavioural features are also seen, including stereotypic hand movements, hyperventilation and…

This research is an examination of the interactions between 19 pairs of student teachers and cooperating teachers engaged in guided reading instruction in Grades 1 through 3. As the basis for the study, the authors analyzed interaction patterns through conducting content analysis (Van Sluys, Lewison, & Seely Flint, 2006) and discourse analysis…

Twenty-two- and 27-month-old children were tested for their understanding of pretending as a specific intentional action form. Pairs of superficially similar behaviors--pretending to perform an action and trying to perform that action--were demonstrated to children. The 27-month-olds, and to some degree the 22-month-olds, showed in their responses…

During the past 20 years, a significant body of literature has emerged focusing on the application of Dabrowski's theory of positive disintegration (TPD) to the study of gifted individuals. Although much of this literature is prescriptive, some research reports spanning this time period are available. A perusal of research on TPD's applicability…

A good deal is now known about the neural circuitry involved in how conditioned fear can augment a simple reflex (fear-potentiated startle). This involves visual or auditory as well as shock pathways that project via the thalamus and perirhinal or insular cortex to the basolateral amygdala (BLA). The BLA projects to the central (CeA) and medial…

The evolution of the internet has made online portals a popular means of surfing the internet. In internet commerce, understanding the post-adoption behaviour of users of online portals can help enterprises to attract new users and retain existing customers. For predicting continued use intentions, this empirical study focused on applying and…

In recent years there has been increasing interest in the phenomena of "gaming the system," where a learner attempts to succeed in an educational environment by exploiting properties of the system's help and feedback rather than by attempting to learn the material. Developing environments that respond constructively and effectively to…

Introduction: In this paper, we discuss the link between information sharing and organizational knowledge production in two very different organizations; a company that handles insurance claims and a small, entrepreneurial hi-tech company. We suggest that this link has not been adequately addressed by studies of information behaviour, though a…

While Gottlieb recognized the significance of biological factors for behavioral development, the system of psychology he developed did not cast the discipline as a purely biological science. Rather, genes, brains, hormones were understood by him as participating, rather than causal factors in behavioral origins. He worked from two basic principles…
