Tested the hypotheses that errors of ommission would occur more frequently than errors of commission and errors would be related to stimulus complexity. A total of 48 children from grades 1 and 3 were given a memory task (involving visual and haptic memory) for recognition of random polygons. (MS)

Investigated the hypothesis that impulsive children differ from reflective children in their preferred strategy of information processing, based on extent of stimulus analysis. The experiments employed third, fourth and sixth graders and a variety of tasks including matching, grouping, recall, and concept attainment. (MS)

Recent studies have reported that preverbal infants are able to discriminate between numerosities of sets presented within a particular modality. There is still debate, however, over whether they are able to perform intermodal numerosity matching, i.e. to relate numerosities of sets presented with different sensory modalities. The present study…

So far as we know, the brain is unlike any other structure in the universe, and perhaps only the vast complexity of the universe itself presents conceptual problems equally impenetrable. While much that is useful has been learned, the working of the brain remains elusive. (MT)

A set of studies examined infant categorization of the orientation of visual stimuli by establishing a categorization function for the orientation continuum; attempted to determine a perceptual boundary between "oblique" and "vertical"; and explored the relationship between discrimination abilities and the perceptual boundary.…

Argues that reality is different and unique for every species and every individual within a species. Language plays an integral part in the construct of human reality and brings intellectual order to the world of the senses. (MDM)

Notes that people often see what they expect to see, have learned to see, or want to see. Presents theoretical discussion of perception and cognition. Identifies 10 skills for correcting perceptual and cognitive processes involved in dealing with incoming stimuli. Proposes that these skills will increase social workers' accuracy in making…

Simulator-based research has shown that pilots cognitively tunnel their attention on head-up displays (HUDs). Cognitive tunneling has been linked to object-based visual attention on the assumption that HUD symbology is perceptually grouped into an object that is perceived and attended separately from the external scene. The present research…

A previous finding argues that, for faces, configural (holistic) processing can operate even in the complete absence of part-based contributions to recognition. Here, this result is confirmed using 2 methods. In both, recognition of inverted faces (parts only) was removed altogether (chance identification of faces in the periphery; no perception…

It is widely assumed that high-level visual processes subserve the attentional blink (AB). Recent evidence from studies of visual masking during the AB that were designed to directly test the contributions of high-level masking effects, however, have failed to provide empirical support for this position.The implication is that low-level visual…

This study examined numerosity comparison in 3-year-old children. Predictions derived from the analog numerical model and the object-file model were contrasted by testing the effects of size and ratio between numerosities to be compared. Different perceptual controls were also introduced to evaluate the hypothesis that comparison by preschoolers…
