Examined whether a copy theory of memory that views memory as essentially a library of stored experiences, or a generative memory model that depends on constructive and integrative processes is more descriptive of the memory representation of children and adults. (Author/SDH)

One hundred and sixty subjects ages 7, 9, 11 and 21 years judged the standard Brentano form and a dot form of the illusion of 5 trials at 30 second intervals. (LLK)

This research project assessed: (1) the practicality of recording heart rate in 18-month-old infants as they watched events filmed on color, silent motion picture films; and (2) the validity and sensitivity of heart rate change as an index of differential attention arousal elicited by changes within and between complex visual events. The research…

The efficacy of gating in the processing of simple, multidimensional stimuli was investigated. In Experiment 1, a continuous classification task was used, with subjects sorting cards according to binary dimensions of line orientation and location. Results suggested that orientation and location are integral dimensions, facilitation occurring with…

This study was designed to determine whether infants could perceive action role reversals when the direction of action is ruled out as a cue; whether infants consider inanimate, nonpotent objects to be unlikely agents; and whether both these discriminations could be reliably reflected in the heart rate response. (Author/SB)

Two studies explored the hypothesis that young children perceive integrally some stimuli that older children perceive separably. In both experiments, kindergarten, second- and fifth-grade children were required to classify sets of stimuli that varied in size and brightness. (SB)

Examines the development of intermodal perception in infancy by means of a new method, the intermodal learning method. Results support the claim that only subjects who had been familiarized with appropriate and synchronous film and soundtrack pairs showed evidence of intermodal learning. (Author/RWB)

Normal and retarded children's use of color, number, length and continuous quantity as attributes of identification was assessed by presenting them with contrived changes in three properties. Surprise and correct memory responses for color preceded those to number, which preceded logical verbal responses to a conventional number-conservation task.…

Reviews research on viewers' understanding and retention of television news broadcasts; discusses the cognitive processes of memory and comprehension; and develops two models, one based on episodical memory and the other on semantic networks. Guidelines are offered for research based on both of these models. More than 40 sources are cited. (EAO)

Sighted subjects assembled puzzles under separate conditions of visual-haptic perception and used vision and touch simultaneously to illustrate visual-type involvement and links in haptic encoding processes. A cognitive component in perceptions was found. When visual input was inadequate or independent of haptic perception, tactual information was…

Reports effects of context that are entirely perceptual. Visual discrimination was enhanced when line segments were flashed in a region that was perceived as a figure. Discrimination was substantially degraded when the same region was seen as ground although the physical stimulus remained identical throughout figure-ground reversals. (Author/JN)

Examines the role of basic cognitive-processing efficiency as the source of developmental variance in cognitive performance. Two experimental tasks, memory and visual scanning, were used to investigate age effects on the search-processing parameter. Subjects were 9-, 11-, 13-, and 15-year-old children. (CM)

Normal and learning disabled children were presented with visual and auditory items for free and cued recall. Deficits in semantically cued recall for children with one impaired modality originated at presentation time, perhaps because of separate pathways linking the auditory and visual modalities to the semantic system. (Author/RD)

The extent to which an orienting activity exerts control over the encoding process was studied. Two experiments were reported in which associative meaningfulness was varied under conditions of semantic and nonsemantic processing. Both experiments showed effects of meaningfulness following both semantic and nonsemantic tasks. (Author/MH)
