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)

High state-anxious subjects solved fewer problems than middle or low state-anxious subjects under no memory-aid conditions, and all anxiety groups performed comparably with memory aids. High state-anxious subjects tended to use less focusing strategy when memory aids were unavailable. (Author/CP)

Three experiments investigated the effects of context on the use of limited processing resources in word recognition. The effect of context on the resources consumed in word recognition is restricted to aspects of processing that can be delayed until the subject is required to select an overt response. (Author/RD)

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.
