Examined were the effects of number of stimuli and of two different stimulus modalities on the discrimination learning of 17 autistic children (mean age 57 months). Discrimination training was carried out in three groups with varied light and sound stimuli. Among findings was that mental age was negatively correlated with trials to criterion and…

This study examined the ability of preschool children to process and use conceptual category information in a disrcimination learning task. A total of 60 boys and girls between the ages of 2 1/2 and 4 years completed a 3-choice discrimination learning task. On each of 12 trials, a child was presented with three magazine photographs: one of an…

This book is an introduction to the psychological study of basic learning processes in children. Written for students who are not majors in psychology and who do not have much familiarity with the technical vocabulary of psychology, it has two themes: even the most basic kinds of learning are included by cognitive processes or mental activities;…

A series of investigations which simultaneously manipulated parameters of reinforcement and age and sex of children were conducted in order to further describe the learning process in children. In addition, an attempt was made to relate perceived parental discipline to performance in the discrimination learning tasks employed in this research. The…

A report is presented which relates to a general hypothesis suggested by previous data on visual response to faces that in the first weeks of life infants develop expectations regarding the human face. Three predictions were made: (1) Silent human faces would elicit less direct regard than faces accompanied by voices; (2) A familiar face would…

Eighty-four nine year old children, twelve in each of seven experimental groups, learned a two-choice successive discrimination problem. The parameters that were systematically manipulated included: (1) immediate versus delayed reinforcement; and (2) forced preresponse stimulus exposure versus stimulus exposure during the delay interval,…

The study found that providing feedback and goals in an accelerating standards condition had a positive effect on the learning of eight retarded children (mean age 9 years) on a five-choice discrimination task requiring vocabulary and perceptual competence. (Author/DB)

The present study operationally defines selective attention in terms of tactile observing responses measured by percentage contact time per trial to the relevant stimulus dimension, and investigates the changes of these responses in a discrimination shift paradigm under the effect of overlearning.
