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)

Investigated the effect of increasing familiarization time on the visual recognition memory of 6- and 12-month-old full-term and preterm infants. Results suggested that persistent differences exist between preterm and full-term infants throughout at least the first year of life in this fundamental aspect of cognition. (Author/RH)

The use of linguistic and extralinguistic information in identifying conversational topics from static and active picture stimuli was studied in three- and five-year-olds. While implicit topic definition was sufficient for five-year-olds' responses, explicit definition was necessary to evoke similar responses from the younger children. (MSE)

Effects of learning names for random nonsense shapes prior to a probe-type serial-recall task were investigated in disabled readers. No differences among reading groups on recall strength of primary recall were found, suggesting similar verbal skills. (Author)

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…

Examines the hypothesis that an attentional preference for an imitator is a function of the magnitude of reinforcement associated with that person, and measures response uncertainty, a construct considered important in the effectance arousal theory often used to explain "being imitated" effects.

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

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)

Infants viewed two objects that bounced in synchrony with two percussion sounds in order to learn about the relationships between sound and object. Learning was revealed in two ways: in a search test and in a transfer test. (Author/DB)

Studies demonstrate increasing glucose metabolic rates in human primary (PVC) and association (AVC) visual cortex as complexity of visual scenes increase. AVC increased more rapidly with scene complexity than PVC and increased local metabolic activities above control subject with eyes closed; indicates wide range and metabolic reserve of visual…

Adults' geometric analogy solution was investigated as a function of systematic variations in the information structure of items. Latency data from verification of true and false items were recorded. A model incorporating assumptions about the form of item representation, working memory factors, and processing components and strategies was…

Preferential looking at stimuli varying in temporal frequency was examined in 11 prematurely born infants. The relationship between amount of looking and stimulus frequency yielded a significant linear trend with the fastest frequency used (4 hertz) being most preferred. (Author/DB)

Two studies of visual recognition memory in infants demonstrated 9-month-olds had greater retention ability than 6-month-olds. Six-month-old infants had difficulty recognizing stimuli over short delays, even when distractors were absent. Results are discussed in terms of memory changes possibly occurring at 9 months.

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)

Educational case studies of three multiply handicapped blind children (five to ten years old) are presented in a discussion of visual stimulation approaches. Objectives of activities such as coupling a light with a sound-producing object are described. (CL)
