Four severely retarded and four nonretarded adolescents learned compound discriminations in the haptic (touch) modality using D. Ray's conflict-compound procedure. Subjects evinced selective attention effects in posttraining tests conducted in the haptic modality. Visual transfer tests revealed the effects of conflict-compound discrimination…

Fifty-three children (ages 5-9) were individually tested on their ability to select pictures of monosyllabic words presented diotically via headphones. Tasks were presented in quiet and under three noise (distractor) conditions: white noise, speech backwards, and speech forward. Age and type of distractor significantly influenced test scores.…

Assessed students' ability to discriminate between two generalized personality interpretations, which varied in their base rate accuracy within a student sample in two experiments. Students recognized that the two generalized personality interpretations differed in their base rate accuracy and that neither interpretation described the students as…

The paper reviews contributions of J. Piaget and others to the understanding of perception's importance in the cognitive development of mentally retarded children. The effects of poor discrimination learning on IQ scores are noted. (CL)

A longitudinal study of first, third, and fifth grade students tested skills involved in the teaching of music reading and concluded that the aural-to-aural intrasensory task was easiest for children to learn. (Author/CJ)

A framework for using and changing concepts in the study of science is described. (JD)

Efficiency was compared between three procedures for sequencing examples with minimal stimulus variation between adjacent positive and negative examples: dynamic, static, and static with maximal differences between pairs. For young children, increasing relevant feature saliency and altering a single stimulus to generate examples reduced training…

Apparently contradictory findings regarding the locus of information processing differences between retarded and nonretarded persons were discussed. (Author)

A procedure (either computerized or manual) designed to assess the discrimination learning thresholds of low functioning psychotic and retarded children is described. (Author)

The study indicated that remediation of a broad spectrum lower level skill can enhance the ability of the learning disabled to perform academic tasks which incorporate that skill, even without specific remediation of the academic skills themselves. (SBH)

This review argues that an hypothesis about longitudinal development may be derived from, and tested exclusively by, cross-sectional data, when the potential sources of interpretive errors are dealt with adequately. The argument is illustrated by cross-sectional data relevant to developmental mediation theory. (Author/SS)

This experiment is concerned with delineating various aspects of pretraining that contributed to the improved hypothesis-testing strategies of 150 kindergarten children. (MP)
