Described is a study which relates Piaget's theory of cognitive development to Lowenfeld's types of perceptual aptitude (i.e., visual v haptic orientation). General interpretations of questionnaire results from university students (N=312) are made that postulate a relationship linking incidence of perceptual and logical ability. (CS)

The perceptual-linguistic stimulus distinction for auditory stimuli was examined with 35 trainable and severely retarded (age 8 to 20) and 31 nonretarded (age 3 to 5) students. Retarded and nonretarded students performed similarly on auditory-perceptual stimuli. Nonretarded students performed significantly better than did retarded students on…

Four experiments show that observers can selectively attend to one of two stationary superimposed pictures. Selective recognition occurred with large displays in which observers were free to make eye movements during a 3-sec exposure and with small displays in which observers were instructed to fixate steadily on a point.

The time needed to process visual feedback information for the control of aimed movements was investigated in two experiments. Examination of movement patterns indicated that the average time between presentation of visual error information and initiation of a movement correction was 135 msec, which is shorter than previous estimates.

This experiment tested the ability of people to recall the locations of buildings in a familiar campus setting. Ten graduate students represented the relative locations of buildings by pairwise distance judgments and by direct mapping of locations on a Tektronix cathode ray terminal. Both methods led to accurate judgments. (Author/CTM)

This experiment investigated preferences for the location of facilities in an ideal town. Ten graduate students represented the relative locations of facilities (home, school, factory) by two methods: (1) pairwise ideal distances on a 100-point scale and (2) direct planning of locations on a Tektronix cathode ray screen.

Three experiments on the coding and retention of kinesthetic (movement-generated) information were performed on two groups of mildly retarded children varying in mental age. (Author/DLS)

The cascade model of information processing is compatible with the relation between time and accuracy in speed-accuracy trade-off experiments. Findings regarding the additive factors methods led to reexamination of conclusions drawn from several studies about the locus of perceptual and attentional effects on processing. (Author/RD)

Reviews research and current knowledge regarding infant auditory and visual perception and concludes that from a very early age, infants are able to perceive the world around them and organize their perceptual experience. Outlines areas for future research and application. (GC)

A series of possible explanations for learning disabilities (LDS) couched in terms of information processing capabilities was tested by comparing the performance of LDS children on several types of information processing tasks with that of a control group. Subjects were 28 LDS children (10-11 years old) and 24 elementary school students of the…

The interdisciplinary approach of cognitive neuroscience in studying mind-brain relations is discussed. (SA)

Discusses cognitive style (the degree to which perception is influenced by environmental variables) and cognitive control (which focuses on the regulation of perception by the ego). Concepts addressed include field dependence-independence, field articulation, conceptual style, cognitive tempo, intrusive information, focal attention, and…

A contrastive analysis should describe the different processes of conceptualization in the languages under consideration. Furthermore, a detailed semantic analysis of linguistic items should be undertaken to discover perceptual strategies which force the speaker to use these items. Research in psycholinguistics is valuable in these tasks. (DB)

Resolution of cognitive dissonance following a pleasant and unpleasant task was examined under conditions of high and low justification with 60 male psychology students. Numbers were written at random and other tasks were completed followed by description of task to another subject. Mode of dissonance resolution was found to be a function of…

Four computer-animated tasks were created to analyze the underlying structure of emerging phonological awareness at 3.5 years of age and to explore factors that influence children's (n=91) performance. The children were able to master tasks demanding identification, blending, and continuation of phonological units. Analysis supported two major…
