To determine whether increased teacher use of student ideas would produce increased verbal initiation, an experiment was conducted with 16 second grade teachers and their classes. First, a series of observations were made under normal class conditions to determine the usual percentages of teacher use of student ideas and student initiation. Then,…

The effects of different levels of rehearsal quality on serial recall, over and above simple labeling, were studied in a sample of 104 kindergartners. Subjects were randomly assigned to four experimental conditions. In one condition the subject and experimenter rehearsed together; in a second condition only the experimenter rehearsed; in the third…

A timeout stimulus control procedure for reducing self-stimulation and disruptive behaviors in autistic children was examined. The three subjects were diagnosed as autistic, exhibiting numerous behaviors incompatible with learning. Severe hand biting, inappropriate noises, and prolonged tantrums were the target behaviors linked with the timeout…

This study was designed to determine if the failure of previous investigations to find habituation and response to novelty in infants younger than 2 months of age was because the stimuli used were too complex or because a constant number of trials rather than an individual criterion of habituation was used. A total of 24 infants between 5 and 6…

The purpose of this study was to determine if the reversal (i.e., mirror image) of a two-dimensional visual image would affect viewers' perceptions of selected aesthetic dimensions, using semantic differential scales as criterion measures of visual meaning. One hundred-twenty-five students who were enrolled in a basic introduction to mass…

Several experiments involving approximately 130 6-year-old children were conducted to examine the effects of overt illustration on first graders' learning from oral prose. In all experiments, experimental Ss heard prose selections after or during which they illustrated selection content with plasticized figure cutouts and background scenes while…

Children living in the deprived environment of Appalachia were studied to determine if they showed a limited verbal response to stimuli in their environment, and if their emotional characteristics differed from those of advantaged children. An earlier study (1957) of American Indian children living on a reservation provided the stimulus for this…

Sixty-three children ranging in age from three to nine years made age judgments on drawings of human figures. The stimuli consisted of four different male figures drawn according to typical physical characteristics of the middle-aged adult, adolescent, child, and infant. The figures were reproduced in two sizes and were presented to the subjects…

The relationship between color cues, figure form, and size discrimination was investigated. Subjects were 28 kindergarten students selected at random from a lower socioeconomic elementary school and 28 grade-3 students from the same school. From a higher socioeconomic area school, 28 grade-3 students were selected. In addition, 12 slow readers in…

This study used a "disguised-structured" technique for determining the differential saliency of race and affect on preference behavior of 60 5-, 6-, and 7-year-old Negro and Caucasian children. Positively and negatively valued objects were distributed by subjects among photographs of happy and sad Negro and Caucasian children. No racial preference…

The learning effects of display motion in procedural learning tasks were examined in two studies. In the first study, two videotapes with identical sound tracks were constructed--one using the recorded television camera motion, the other substituting a parallel series of still camera shots. The results showed a superiority of the motion condition.…

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…

Differentiation of the effects of cultural deprivation and achievement characteristics as they relate to auditory comprehension and by implication to potential reading ability was investigated. A total of 80 eighth-grade students were classified into four experimental groups: deprived-achievers, deprived-nonachievers, nondeprived-achievers, and…

In order to investigate the effect of reinforcement on learning, 21 disadvantaged black children, 4 to 5 years of age, were divided among three treatment groups. Group I children received only feedback (information) as to the correctness or incorrectness of their responses. Group II children received a raisin for each correct response, and group…

Research measured the attention of deaf children to captioned visuals using a conjugate reinforcement procedure. The subjects were six deaf children aged eight to 15, whose IQs fell within the normal range. The stimulus material consisted of slides produced from a captioned filmstrip; subjects controlled the presentation of the stimulus via a…
