The present study replicated the procedure of Kausler et al. (1975) as a means of testing further the hypothesis that the processing of wrong items differs qualitatively, as well as quantitatively, from the processing of right items. (Author)

The study compared the effectiveness of a traditional training procedure (least-to-most restrictive prompt sequence) and a prescriptive training procedure (utilizing ongoing behavioral assessment data to identify discriminative stimuli) with four severely/multiply handicapped students (ages 11-19). Results indicated both procedures were effective…

The effectiveness of a preschool peer-tutor to facilitate generalization of two preschoolers' performance on two academic tasks was evaluated. The peer-tutor apparently acted as a distracter rather than a facilitator; on some occasions time to complete a discrimination task was greatly lengthened by the presence of the peer-tutor. (SLD)

To determine whether the effects of noncontingent feedback were transferable, 64 first-grade boys first were given a two-choice discrimination task and then a different contingent task. Results suggested that, even when conditions change, experience with prior noncontingent feedback disrupts the ability to use contingent information. (Author/BE)

The article provides an overview of central auditory processing (CAP) dysfunction and reviews research on approaches to improve perceptual skills; to provide discrimination training for communicative and reading disorders; to increase memory and analysis skills and dichotic listening; to provide speech-in-noise training; and to amplify speech as…

Results of a study with 10 moderately retarded adolescents on the salience of transverse compound stimuli (combinations of positive and negative cues) were interpreted as an instance of developmental changes in unlearned stimulus salience hierarchies. The low saliency of transverse compounds was suggested to be related to reading difficulties.…

This study investigated vowel discrimination in 8-week-old infants. Using a nonnutritive, high-amplitude sucking measure in a habituation-dishabituation paradigm. (Author/SB)

Impulsive second grade, inner-city children, were trained to improve their search strategies on visual discrimination tasks. Groups with training improved their search strategies, while the untrained control group did not. (ST)

One of the concerns of the present study was to determine the effects of Right and Wrong items under conditions that do not reduce the opportunity to rehearse the Right items in practice. (Author/RK)

The solution of relational size problems was facilitated when children were told to find the smallest member of the series. Children who could not do so could not solve the problem. (ST)

Studied the relationship between auditory ability and oral form discrimination in children with varying degrees of speech and language development. Results lend support to motor theory of speech perception. (ST)

Purpose of the present experiment was to compare performance of four- and six-year-olds on a conjunctive concept task in which the two relevant values were either within a single dimension (unidimensional) or from two different dimensions (bidimensional). (Authors)

It is urged that investigators lay aside demonstrations of the existence of mediation in young children as focus of research, substituting a search for the conditions of its occurrence. (Authors)

The orderly increase in the proportion of subjects who make optional reversal shifts over an age scale that now encompasses a range from 3 to 18 is confirmed. (Authors)
