Two boys, ages 7 and 9, with severe developmental disabilities were taught to use requests conditionally (when desired items were proximally distant) to obtain desired snack items. Results suggest that the conditioned discriminations were established quickly and both learners generalized their conditional discriminations to other contexts.…

Using a conditioned suppression task, we investigated extinction and renewal of Pavlovian modulation in human sequential Feature Positive (FP) discrimination learning. In Experiment 1, in context a participants were first trained on two FP discriminations, X[right arrow]A+/A- and Y[right arrow]B+/B-. Extinction treatment was administered in the…

This paper describes further research on a learning procedure for layered networks of deterministic, neuron-like units, described by Rumelhart et al. The units, the way they are connected, the learning procedure, and the extension to iterative networks are presented. In one experiment, a network learns a set of filters, enabling it to discriminate…

Study supported by grants from the University of Connecticut Research Foundation and from the U.S. Office of Education.

Two way analyses of variance and cross-group descriptive comparisons assessed the effectiveness of the Siop Poison Prevention Program, which included an educational program and the use of warning labels, on improving verbal and visual discrimination of poisonous and nonpoisonous products for preschool children. The study sample consisted of 156…

Four-, five-, and six-year-old children were used as subjects in this investigation. There were 192 experimental and 96 control children used, divided equally between the three age groups. The experimental children received a 1-minute pretest exposure procedure in which 1/4 of the children observed 4 two-dimensional stimuli (irregular pentagons),…

Review of reversal learning data obtained from Ss of various developmental phases suggested that overtraining increases perseveration in pre-school children, and decrease perseveration in older (e.g., 1st grade) children. The present experiment tested this apparent trend. Children of two age groups (X = 4 yrs., 4 mos., vs. X = 6 yrs., 5 mos.)…

Intended for secondary English teachers, the materials and ideas presented here suggest ways to use media in the classroom in teaching visual and auditory discrimination while enlivening classes and motivating students. Contents include "Media Specialists Need Not Apply," which discusses the need for preparation of media educators with…

A total of 186 kindergarteners were pretested on number conservation and two cognitive style measures representing Kagan's impulsivity-reflectivity dimension and Santostefano's leveling-sharpening dimension. From this sample 72 nonconservers were assigned to one of three conservation training conditions: reversibility training, discrimination…

This book is a compilation of literature and research concerning how children learn. The first chapter is a historical introduction to research in learning that summarizes the major developments of the last 100 years and relates these developments specifically to children's learning. The main body of the text is divided into six major topics: (1)…

Reversals in poor and normal second-grade readers were studied in relation to their whole phonological error pattern in reading real words and nonsense syllables. Error categories included sequence and orientation reversals, other consonants, vowels, and total error. Reversals occurred in quantity only in poor readers, with large individual…

The effectiveness of short-term training on two communication tasks was assessed with seven and one-half olds. Twelve subjects were trained in trios for six sessions on tasks requiring complete description of a design for a listener to reproduce, and tasks requiring communication of critical information for a listener to discriminate the same…

This document reports on a study of how the eye and the hand become functionally coordinated during growth. A specific question researched is "How do children use their hands as perceptual tools for exploring objects in order to acquire information about them?" It was assumed that a pre-school child would have evolved a form of eye-hand…

This study was designed to examine the effects of age and sex on susceptibility to field dependence training and to determine whether the field dependence phenomenon is a function of cognitive style or of a general inability to make correct judgments because of confusing and inaccurate information. (MS)

This study investigated attention to and recognition of components in compound stimuli among infants and preschoolers. Oddity tasks with preschoolers and familiarization/novelty-preference tasks with infants demonstrated successful discrimination among stimuli components on basis of edge property information. Matching tasks with preschoolers and…
