Visual field theory was examined insofar as television viewers' perception, retention, and preference for still visual images were concerned. The purpose of the experimental investigation was to determine whether the specific shapes, colors, and placement of visuals within a picture frame affected viewers' abilities to perceive, describe, and…

Examined were the effects of number of stimuli and of two different stimulus modalities on the discrimination learning of 17 autistic children (mean age 57 months). Discrimination training was carried out in three groups with varied light and sound stimuli. Among findings was that mental age was negatively correlated with trials to criterion and…

TO DETERMINE THE COMPARATIVE AMOUNT OF LEARNING THAT OCCURRED AND THE AUDIENCE REACTION TO MEETING EFFECTIVENESS, A 20-MINUTE INFORMATIVE SPEECH, "THE WEATHER," WAS PRESENTED WITH VISUAL AIDS TO 23 AND WITHOUT VISUAL AIDS TO 23 INFORMAL, VOLUNTARY, ADULT AUDIENCES. THE AUDIENCES WERE RANDOMLY DIVIDED, AND CONTROLS WERE USED TO ASSURE IDENTICAL…

INJURY TO THE NERVOUS SYSTEM CAN RESULT IN DEFECTS OF FIGURE FORMATION SUCH AS LACK OF PRECISION OF FIGURE AND UNCERTAINTY AS TO WHICH IS FIGURE AND WHICH IS GROUND. IMPAIRMENT OF FIGURE GROUND PROCESSES MAY BE LIMITED TO ONE AREA OF THE NERVOUS SYSTEM FUNCTION. DISTURBANCE IN FIGURE FORMATION MAY NOT RESULT IN PERCEPTION DISTURBANCES, DEPENDING…

In order to determine if infants possessed contingency awareness and if it were related to a temporal unit, two hypotheses were constructed. (1) Reinforcement of a response would probably lead to emission of that response only if the infant's next response occurred within a period of time during which he could remember the preceding…

This study examined the ability of preschool children to process and use conceptual category information in a disrcimination learning task. A total of 60 boys and girls between the ages of 2 1/2 and 4 years completed a 3-choice discrimination learning task. On each of 12 trials, a child was presented with three magazine photographs: one of an…

This study used the behavioral contrast paradigm to assess the excitatory and inhibitory capabilities of young infants. Behavioral contrast is described as the phenomenon whereby the rates of responding in the presence of two stimuli, both of which were previously associated with reinforcement, change in opposite directions when only one of them…

Sixty-four preschool children were individually trained on a task requiring them to recognize an isolated phoneme in a word context. A learning set design encompassing 192 trials over eight days was employed. The major factors investigated were: the presence of a redundant visual cue; phoneme type (stop vs. continuant); phoneme position (initial…

In this study, kindergarten children classified as impulsive received (1) visual analysis training involving either motor or verbal responses, (2) were trained only to delay their responses, or (3) were assinged to a control group receiving no training. While all treatment groups showed a significant decrease in errors on the Matching Familiar…

This paper reports a study which investigated 2-month-old infants' auditory discrimination of tone quality in the male voice, extending a previous study which found that voice quality changes (soft versus harsh) in a female voice were discriminable by infants at this age. Subjects were 20 infants, tested at 8 and 9 weeks of age. Each infant was…

A method for stimulating and facilitating organizational writing in the secondary school is described in this paper. Pictorial sequences are coordinated and arranged to typify the four major styles of writing: narrative, descriptive, expository, and persuasive. These sequences both portray a meaningful event in keeping with the writing style and…

Described are basic electronic features and results of research on the Video Articulator, an electrovisual speech analyzing device which has been used in speech training for the hearing impaired. Data are presented from studies of the validity and reliability of video patterns produced by various speakers using the Video Articulator and by the…

This experiment was designed to test the hypothesis that subjects must know the length of the viewing matter they will be scanning before the target is presented in order to scan efficiently. Adult subjects were required to scan visually for a predetermined item. Targets were one, two, or four letters in length and the pairs of slides shown on…

This study was conducted to determine whether the recent semantic-physical processing distinction that Jenkins and his associates have invoked to account for differences in subjects' recall and clustering of verbal materials could be extended to include pictorial materials as well. In the first experiment, second-grade children were exposed to 15…

Evaluated were the properties and fine structures of averaged visually evoked potentials (AVEP) in 60 normal children between the ages of 2 and 9 years. Electroencephalographic recordings were taken while white diffuse flashes were used to deliver visual stimuli to the Ss. Three types of AVEP patterns were discerned, with no relationship observed…
