Nonsense forms with nonsense labels were utilized in a match to sample task to observe whether children's word extensions are based on static form characteristics or on functional action characteristics. The stimuli consisted of: (1) a single model object which performed an action; (2) a selection array consisting of one object similar in form to…

AS PART OF THE RESEARCH ON THE INFLUENCE OF RESPONSE-CONTINGENT REINFORCERS ON THE LEARNING AND PROBLEM-SOLVING BEHAVIOR OF CHILDREN, THE EFFECTS OF A LIMITED NUMBER OF VARIABLES ON THE PERFORMANCE OF CHILDREN OF THREE AGE LEVELS (4-5, 7-8, AND 10-11), SELECTED EQUALLY FROM MIDDLE- AND LOWER-CLASS BACKGROUNDS, WERE INVESTIGATED. THE EXPERIMENTAL…

The article reviews and analyzes existing assistance procedures with moderately to severely developmentally disabled students. Procedures considered include those performed prior to responding and those involved with fading assistance. Implications for selecting assistance procedures are examined. (CL)

Describes two experiments conducted to explain why retarded children of younger mental age appear to be more selective on discrimination tasks containing relevant redundant cues than do children of older mental age. Findings are consistent with the hypothesis that the latter group of children are overselective because they tend to solve…

According to Hypothesis (H) theory, learning should be very difficult when the number of Hs the subject samples from is very large and/or the correct H is not available. These assumptions were tested with third- and fourth-grade children. In general, results supported these assumptions. (Author/MP)

Three studies of elementary school children's problem-solving procedures in intentional discrimination tasks are reported. Subjects were children selected from kindergarten and grades 2, 3, and 6. (Author/MP)

Three experiments investigated 4-, 6-, and 8-month-olds' perception of the audible, visible, and combined attributes of bimodally specified syllables. Results suggested that at 4 months, infants attended primarily to the featural information, at 6 months primarily to the asynchrony, and at 8 months to both features independently. (Author/KB)

This study investigated the effects of two stimulus manipulations (spatial distinctness and number of dimensions) on the performance of 24 kindergartners and 24 fifth graders in (1) tasks requiring distributed attention and (2) tasks requiring selective attention. Results suggest that kindergartners attempt to use one processing mode (distributed…

Earlier studies found that recall scores of information central to the task increased with age while incidental information recall scores remained constant. This study repeated the earlier ones modifying procedures of instructions, testing, and schedule of recall. Also, it tested the effect of labeling pictorial stimuli. The sample of 253 children…

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…

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…
