Through contributions from top leaders in Autism Spectrum Disorder (ASD), "Children and Youth with Autism Spectrum Disorder" examines the ASD research literature, discusses procedural implications, and makes recommendations for future practice and inquiry. It combines the most recent developments in established practices with newer and…

Children's theatre in the UK is thriving. Debates about why children should watch theatre and what educational, emotional and expressive benefits it can provide inform cultural policy on education. Children aged 4-11 are increasingly taken to watch tailored theatre performances, yet there has been virtually no reflective research on what theatre…

Examines the extent to which an infant's social initiative resists or is modified by three variations in the behavior of adult responsiveness: repeated responses, varied responses, and eye aversion. (HOD)

Reports on four experiments on pattern perception in four-month-old infants. The first experiment examined preference for patterns varying in structure; the second examined encoding patterns from different subset sizes; and the last two experiments examined changes in the size, position, and orientation of the habituation pattern. (HOD)

To document movement patterns and to examine developmental interrelationships, the ontogeny of rooting, lip, lateral tongue, mouth opening, biting, and Babkin reflexes and the development of emerging chewing behaviors were observed in two normal infants over a period from 1 week to 35 weeks of age. (Author/RH)

Two studies examined the relationship between cognitive rigidity and cognitive inertia, with a total of 52 children and adults with mental retardation and 50 nonretarded individuals. Findings provide some support for the theory that there are age-related inherent structural differences leading to greater rigidity in older adults. (DB)

This response to four papers on the nature of reinforcement focuses on the implications for application of theory to practice. The response addresses: reversibility of single-incentive selective associations; response deprivation, reinforcement, and economics; the substitutability of reinforcers; and delay reduction. (DB)

Demonstrates that a mother's perceptions of and behavior toward an infant can be influenced by knowing whether the infant was born prematurely or full-term. Differences in maternal behavior arising from this knowledge appear to produce differences in the infant's behavior. (HOD)

The characteristics of the skill clusters involved in community living response chains were studied, focusing on the length of the chain, the response classes contained in the chain, and the implicit variations within the chain. Instruction of response chains can be enhanced through consideration of the stimulus control strategies used.…

This study focused on the cognitive conflicts experienced by young children in using software programs that provided them with tools to create and/or combine individual graphic elements into larger structures. Six 5-year-old children, none with prior computer experience, were observed using three programs--Kids at Work, Picture Perfect, and…

Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

Describes the Adjusted Agreement Index, a strategy for analyzing collected data from questionnaires utilizing Likert-type scales. Steps involved in using this index and its strengths and weaknesses are outlined, and a case study illustrating how it was used to summarize data on a distance education course package is presented. (MBR)

Tests two hypotheses concerning developmental change in the speed of cognitive processes: (1) age differences in processing time reflect changes that are specific to particular tasks, and (2) age differences in processing speed do not reflect task-specific change but are due instead to more general developmental change. (HOD)

Examines whether young children, aged four to nine years old, are satisfied with their own method of drawing a familiar object, or whether they would ideally like to draw in a more advanced way but are hampered by production differences from achieving this aim. (HOD)

Basic and applied research on variables that influence the extinction of operant behaviors is reviewed and applied to the treatment of behavior disorders. The potential value of a general technology for the use of behavioral extinction is discussed. The paper concludes that current research findings are not sufficient for the development of a…
