Perceived time in complex cognitive functions was studied using college students' estimates of time spent taking a test in relation to examination performance. Significant correlations were found between true scores and students' estimated time. Differences in the perception of time were shown to be consistent with theories of attentional…

A model of context effects in perception is applied to perception of letters. Perception results from excitatory and inhibitory interactions of detectors for visual features, letters, and words. The model produces facilitation for letters in pronounceable pseudowords as well as words and accounts for rule-governed performance without any rules.…

The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

Reviews work on three areas of visual information that are available to readers: information provided by the conventional arrangements of the print on the page, by the features of each letter, and by the shapes of entire words. (HOD)

In four experiments, evidence was found for a complex psychological representation of musical pitch. The perception of music depends not only on psychoacoustic properties of the tones, but also on processes that relate the tones to one another through contact with a well-defined and complex psychological representation of musical pitch.

Nearly twice the amount of variance in complexity scores accounted for by 17 antecedent variables was associated with Black rather than White subjects. The findings were truer of Black males. Independent variables were most strongly correlated with complexity scores for Black females. (Author)

The assumptions underlying the classfication rule-learning description of concept acquisition are critically examined. An alternative characterization of what it means to have a primacy hypothesis and Gibson's position that knowledge of the world is a product of direct perception are discusssed. (Author/RD)

Full-term middle-class, full-term lower-class, and preterm infants were compared on cross-modal and visual intramodal functioning in order to determine whether cross-modal functioning would be impaired in infants born prematurely, or in full-term infants who were being raised in less advantaged environments. (MP)

In a task designed to separate perceptual processes from memory, reading-disabled 12-year-olds showed no perceptual deficits as compared to their peers. However, they exhibited major deficiencies in memory skills, appearing to suffer from a basic information-processing deficiency. (Author/CS)

Reviews recent research on information processing and decision making in orienteering. The main cognitive demands investigated were selection of relevant map information for route choice, comparison between map and terrain in map reading and in relocation, and quick awareness of mistakes. Presents a model of map reading based on results. Contains…

Defines visualization as the product and the process of creation, interpretation, and reflection upon pictures and images. Analyzes, exemplifies, and reflects upon the many different and rich roles that it can and should play in the learning and doing of mathematics. Discusses limitations and possible sources of difficulties visualization may pose…

Several experiments involving 150 college students and adults provide evidence for top-down lexical to phonemic activation in auditory word processing. Results indicate that lexical activation can cause the perceptual process to synthesize a highly functional phonemic code. (SLD)

Summarizes and critiques Berberich's dissertation on cognitive effects on music perception. Comments on the study's unusual data analysis and presentation. States that the main arguments are presented elegantly and clearly, but the study overlooked other issues such as a chapter on related literature. (LS)

The neuronal model shown to code sound-source azimuth in the barn owl by H. Wagner et al. in 1987 is used as the basis for a speculative brain-based human model, which can establish contrastive phonetic categories to solve the problem of perception "non-invariance." (SLD)

Describes a cognitive approach to arts education developed by Harvard Project Zero, highlighting a classroom application project, ARTS PROPEL. Incorporating the competencies of production, perception, reflection, and learning, the project has developed a set of assessment instruments which can document artistic learning during the late elementary…
