A 112-item Multi-Modal Articulation Analysis test was administered to 116 Head Start children ranging in age from 4 years, 6 months to 5 years, 5 months. The test involves presenting to the subject an object, or representation thereof, requiring a one-word response. Four modes of stimulus presentation were used: (1) actual objects, (2) black and…

In this study, developmental changes in duration of the icon (visual sensory store) were investigated with three converging tachistoscopic tasks. (1) Stimulus interuption detection (SID), a variation of the two-flash threshold method, was performed by 29 first- and 32 fifth-graders, and 32 undergraduates. Icon duration was estimated by stimulus…

This paper reports two related experiments, the first investigating whether children 3-7 years old demonstrate Flavell's Level-2 perspective-taking in a cognitively simple task, and the second re-examining children's performance on a task comparable to the Piagetian 3-mountain perspective-taking task. The first experiment involved a task which…

Spontaneous and model-induced production of a valuational style of inquiry was studied in 128 third grade children. Provision of a favorable versus a neutral outcome-expectation, and sex of child failed to influence the results. All modeling groups displayed strong value-question increases over baseline which, without further tutelage, they…

A study of the commonality of associations of 50 lexical and 50 structural words by 80 kindergarten children indicated that (1) there was no significant difference in commonality of responses between lexical and structural words, (2) there was a difference in commonality relations for the sexes, and (3) there was more commonality in responses to…

This report examines the interrelations among several verbalization indexes on a sample of 27-month-old children and the relation of this data to vocalization scores obtained in the first year. Subjects, 67 girls and 75 boys, were firstborn Caucasian children observed at 4, 8, 13, and 27 months. Parent education varied from incomplete high school…

The authors discuss their replications of 2 prominent studies in the area of modeling aggressive behavior; those of Lovaas and Bandura. In the first, they predicted that, given the same socio-economic background, there would be no differences between black and white children in the amount of aggressive play subsequent to viewing an aggressive…

Several studies have indicated that children have difficulty differentiating mirror-image stimuli. In the present study adults were required to classify pairs of horseshoe stimuli as same or different. Response times were compared for stimulus pairs that varied in orientation (left-right vs up-down) and spatial plane of the pair (horizontal vs.…

A study was conducted in which the infants' behavior was allowed to control stimulus duration. A group of five infants were tested once a week from 3 through 14 weeks of age. A second group of five infants were tested once a week from 8 through 14 weeks of age. A third group of 18 infants were tested once at 3, 8, or 14 weeks of age. Once a…

The effects of telegraphic prose upon the comprehension of written and auditorily presented messages were tested. Two separate experiments were conducted. Subjects for the first experiment were 60 undergraduates enrolled in a remedial reading program; subjects for experiment 2 were 100 undergraduates enrolled in an introductory educational…

THE EFFECTS OF SELECTIVE MANIPULATION OF PICTORIAL CONTENT UPON PAIRED ASSOCIATE LEARNING WERE TESTED AND EVALUATED. STIMULUS MATERIAL WAS VARIED BY AUGMENTING CONTOUR CUES AND DIMINISHING IRRELEVANT CUES. FIFTH-GRADE STUDENTS WERE ASSIGNED TO NINE DIFFERENT TREATMENTS, INVOLVING STIMULUS SLIDES THAT VARIED IN TREATMENT OF CONTOUR AND CONTEXTUAL…

Students in grades 4, 6, and 8 were required to indicate whether or not a stimulus word belonged in either of two semantic categories that were held in memory. Results indicated that even for the youngest children semantically similar categories required less search time than dissimilar categories. (GO)

Cortical evoked responses were recorded from 66 nonretarded and 66 Down's syndrome Ss in order to compare the inhibitory processes of the two groups. (Author/PHR)

The study was designed to determine the extent to which auditory and visual stimuli influence certain sound productions of 250 children (preschool-third grade). (Author)

The study assessed task performance of 25 hyperactive and 22 normal children (six to ten years old) with and without within-task color, holding task complexity constant. (Author)
