Heart rate change was used as the index of the orienting response (OR) of 102 kindergarten children. Heart rate change was measured by recording heart rate upon the presentation of tones. 15 similar tones followed by a different, 16th tone, were used. From this data the children were divided into high, medium, or low orientors. Following the…

This study examines some variables that may affect two aspects of syntax in Head Start children; the use of descriptors and the use of complete sentences. Thirty-six children were assigned to six experimental conditions in a design which varied adult verbal modeling, feedback, and sex. Children given adult verbal modeling produced significantly…

Elementary and junior high school students took part in a test involving the probability texture of the language to determine whether spelling ability is related to a student's understanding of possible letter combinations in English words. Two similar groups of 124 fifth grade students and 129 eighth grade students were ranked in spelling ability…

Four experiments were conducted to assess the effects of certain stimulus variables on children's discrimination learning. In general, it was found that word frequency was negatively related to discrimination learning as long as the words were meaningful to the subjects. Moreover, the relationship between word and performance reversed in…

This study investigated whether or not Sights and Sounds, a filmstrip-record series originally designed for speech-hearing handicapped children, could produce perceptual discrimination learning of familiar sounds in primary level educable mentally retarded (EMR) children and whether EMR children were susceptible to perceptual learning via…

Sperry (1961) and others working on split brain learning reported that the two halves function in a nearly identical manner, giving excellent controlled replication of a learning problem. The present experiments were carried out with cats trained in a tactile discrimination apparatus, sometimes being forced to use the left paw, and sometimes being…

The results of a group of studies, the objective of which was to clarify the conditions that account for the effectiveness of verbal approbation, are reported. Among the most significant findings were: (1) that the reinforcement properties of verbal approval are susceptible to distortion, misinterpretation or enhancement and must be applied in a…

Ninety-six children, divided by age (five, six, seven, and eight years) and sex into equal groups, were administered tests of discrimination between leaves, association of leaves with pictures of leaves, sorting leaves into generic groups, and communication of concepts of leaf structure. No sex differences or interactions were found, but there was…

The relationships among the perception, representation, and construction of series are examined within a model of the acquisition of seriation abilities. The model is then related to two experiments with three-, four- and five-year-olds. The key feature of the model is the delineation of parallels among developmental changes in three arenas:…

Provided in the second of two articles is further evidence of the validity of the author's sequence of tactual discrimination tasks for partial development of Optacon use readiness in young blind children. (IM)

The relation between conceptual development and visual exploratory behavior was investigated by engaging eighty-four 3-, 4-, and 8-year-old children in a picture-sorting task to determine whether they would spontaneously and readily discriminate between animate and inanimate objects. (Author/JMB)

Eight severely retarded subjects (ages 9-22), four with functional language and four without, performed identity and nonidentity matching tasks employing objects, photographs, and line drawings. As representational complexity increased, greater difficulty in matching stimuli was observed in the nonfunctional language group, with line drawings…

To estimate the relative effects of three types and three combinations of feedback on children's discrimination learning, a meta-analysis was performed on the findings of 89 studies. In general, reward compared to punishment or to reward plus punishment is the least efficient method of feedback for teaching children discrimination materials.…

Results revealed that (1) relevant verbal experience facilitated learning only for preschoolers, (2) irrelevant verbal experience did not interfere with learning, and (3) visual highlighting exerted no significant effects. (Author/MB)
