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…

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…

A total of 47 6-year-old children listened to stories after which they either constructed pictorial representations of those stories from a set of backgrounds and cut-out figures and objects, or they spent equivalent time classifying geometric figures. The pictorial elaboration task inhibited recall of the stories. This contrasts with results…

Subjects, differing in imagery ability, learned a list of paired associates with the presence of a verbal context related to the stimulus item, with a pictorial context related to the stimulus item, or without the presence of any context. Following testing for recall, the subjects were required to learn one of two transfer lists. Both lists were…

Sixty kindergarten, 60 second-grade, and 60 fourth-grade students performed several memory tasks under one of six conditions. The conditions differed as to the method of presentation of information. The study was focused on developmental changes in children's use of verbal, nonverbal, and spatial-positional cues for memory. The results, in…

To collect word association norms, 100 educable mentally handicapped boys (chronological ages 11 to 16, mental ages 7 to 11.5) responded to 25 nouns from the Mein and O'Connor list of words most commonly used by retarded children. The subjects were individually tested by stimuli typed on cards. The responses of all 100 subjects to the 25 stimulus…

The study investigated the task performance of cerebral palsied children under conditions of reduced auditory input and under normal auditory conditions. A non-cerebral palsied group was studied in a similar manner. Results indicated that cerebral palsied children showed some positive change in performance, under conditions of reduced auditory…

This study tested the possibility of using the optimization techniques of the response surface model in maximizing the response to a concept learning task. A secondary purpose was the investigation of the extent to which findings from concept learning experiments in laboratory settings would generalize to the learning of types of concepts…

A short term memory task was used to explore the effects of color cues and of a condition that permitted rehearsal as compared to one that did not. Eighty subjects per grade at grades 3, 5, and 7 were tested. A stimulus array consisted of five cards, each of which contained pictures that could be designated as central or incidental. The stimulus…

A research project investigated the extent to which children's visual awareness and visual literacy were developed through photography. Thirty-four elementary school students were provided with Polaroid "Big Swinger" cameras; they were given one roll of film per day for eight weeks and allowed to photograph whatever they liked. After…

Forty-eight pairs of children between the ages of 4 and 8 were the subjects of this study of the development of referential communication skills and the use of technology to structure interactions between people. A communication game device was used to present children with sets of four referents on separate screens. The referents were either…

A total of 48 8- to 14-week-old infants were presented with a non-contingently moving visual stimulus and the infants' visual attention was measured. Infants who exhibited decrements in attention to the non-contingent stimulus showed recovery in attention when the same stimulus was made to move contingent upon a motor response. Moreover, wisual…

Seventy-two preschoolers and 72 second graders observed a model choose his "favorites" in a series of common object trios and were then asked to recall the model's choices. Children at each age witnessed the procedure under a fixed level of distraction, under instructions either to 'look' or 'remember,' and under one of three vicarious consequence…

According to the cognitive-congruency principle, humor appreciation peaks when the cognitive demands of the stimulus are congruent with the cognitive level of the child. This study tested the principle with jokes based on concepts associated with concrete operational thinking, conservation of mass and weight. This method provides a satisfactory…

A long-range investigation is being made to define the characteristics required of a television system to simulate a visual environment which will permit target acquisition performance comparable to that obtained in the real world. In this portion of the investigation, target recognition performance under direct viewing conditions was compared…
