The study assessed variations in the indoor and outdoor locomotor mobility of 22 low-vision adults, under normal and reduced illumination. Subjects' visual fields and contrast sensitivities accounted for 39 percent of the variation in mobility performance, whereas their visual acuities were not related to mobility performance.

Thirty learning-disabled and 30 nonhandicapped intermediate grade children were assessed on memory performance for stimulus words, which were presented with congruent and noncongruent rhyming words and semantically congruent and noncongruent sentence frames. Both groups performed significantly better on words encoded using deep level congruent…

A study was conducted to determine generalization performance after training. Eight students with moderate retardation, aged 6-10, were trained and tested on identification of colors, under one of two treatment conditions: single (one example) and multiple (four examples). Greater generalization resulted when multiple exemplars were used during…

Reports the success rates of reference question answering as perceived by librarians and patrons in 36 public libraries. The discussion covers relationships between question answering success rates and factors such as time and effort spent on questions, reference resources and environment, communication difficulties, and type and source of…

Explored age-related memory differences for performed action events of varying familiarity in 50 adults aged 18-31 and 50 adults aged 55-84. Type of encoding and item familiarity influenced immediate and delayed free recall in both age groups. (RJC)

How the dual-task interference effects, observed when subjects attempted to simultaneously perform two simple tasks, are related to capacity limitations in perceptual processing of complex visual displays was studied. Results for a total of 110 undergraduates in 6 experiments support a 2-component theory of divided attention. (SLD)

College students participated in a study to test competing hypotheses derived from Bem's gender schema theory and Spence's gender identity theory. In two samples, sex, self-concept, and spatial activities made significant direct contributions to the prediction of spatial performance, supporting Spence's theory. (RH)

Some experiments concerning concrete-operational Piagetian skills are discussed in light of the interbehavioral approach in order to highlight the interacting role of antecedent stimuli and the setting of events in complex cognitive behaviors. Conservation, class inclusion, and classification are considered. Implications for a theory of…

Varied composition of three-man military teams (N=64) by assigning members according to team composition in all possible combinations of ability and motivation. Found both ability and motivation had an additive effect on crew performance, thus leading to conclusion that when teams perform highly interdependent tasks, performance is apparently…

Describes a study that assessed the attitudes of novice searchers before and after using a laser videodisk system. The discussion covers the relationships between the users' initial attitudes, prior computer experience, and success in using the videodisk system. (11 references) (Author/CLB)

Relative timing of 15 stutterers' speech was compared with 15 nonstutterers, using two fluent utterances of the same phonetic content. Relative timing was not influenced by whether the talker was a stutterer or not, nor by the presence of fluency or disfluency in the environment in which the utterance occurred. (Author/JDD)

Twelve students with autism and 12 with mental retardation, who had passed a first-order test of false belief, were given a second-order reasoning task. No intergroup performance differences were seen. Findings suggest that the difficulty for both groups with the second-order task lies in information processing demands rather than conceptual…

Hearing-impaired and normal hearing children in 2 age groups (5-6 years and 9-12 years) were observed for possible differences in their perception and production of intonation. Results indicated that imitation of intonation carried on nonsense syllables was not affected by age. Hearing-impaired subjects scored much lower than controls in imitating…

This study evaluated the effects of presenting mnemonic devices in conjunction with content information on 41 junior high students' recall performance. Results showed that students with and without learning disabilities within the experimental group recalled significantly more of the reviewed information than did control students. (Author/JDD)

Ten adults with dysarthria of various etiologies, type, and severity were compared to age-matched and gender-matched nondysarthric speakers on 40 short sentences. Results indicated reduced intonation values for the dysarthric group and varying rates as a function of subject group and sentence type. Results suggest that dysarthria is a deficit in…
