Previous reports have demonstrated that the comprehension of sentences describing motion in a particular direction (toward, away, up, or down) is affected by concurrently viewing a stimulus that depicts motion in the same or opposite direction. We report 3 experiments that extend our understanding of the relation between perception and language…

Five experiments investigated the recognition of proper names and common nouns using the lexical decision paradigm. In Experiments 1-3 the case of the initial letter of written stimuli was systematically varied. An advantage was consistently found for proper names written with the first letter in capital. Crucially, response times to proper names…

This paper studied whether abnormal P3 amplitudes in PDD are a corollary of abnormalities in ERP components related to selective attention in visual and auditory tasks. Furthermore, this study sought to clarify possible age differences in such abnormalities. Children with PDD showed smaller P3 amplitudes than controls, but no abnormalities in…

AN ANNOTATED BIBLIOGRAPHY OF TEN STUDIES OR WRITINGS ON PROBLEMS RELATED TO VISUAL PERCEPTION PUBLISHED BETWEEN 1954-1964 IS PRESENTED. THIS ARTICLE APPEARED IN "THE READING TEACHER," VOLUME 20, NOVEMBER 1966. (RH)

Reviews the ideas included in and the debate spawned by the author's paper at the 1974 International Intervisitation Program meeting in Britain. The paper questioned systems theory's adequacy as an exclusive explanation of organizations. (IRT)

Describes an experiment in which the rate of habituation of fixation of 12-week-old infants to a homogeneous stimulus series where a cube was presented in different orientations was contrasted with the rates of habituation to various heterogeneous series where a cube was alternated with some other solid.

Argues that pointing emerges as a component of action-for-self: selective orienting to salient (usually moving or changing things). Pointing with vocalization, followed by pointing with naming, indexes the child's shifting focus of attention. Evidence that pointing emerges for the purpose of intentional communication is lacking. (Author/CB)

The qualities expected of a music critic are discussed. (CK)

Activities related to producing OP Art are described. (DB)

A new grouping principle, which depends on perceived depth relations and follows a hierarchical embedding scheme, states that elements located within a common region of space will be perceived as grouped together. Common region produces clear powerful grouping effects, yet cannot be reduced to any other known grouping factor. (RLC)

Functional magnetic resonance imaging (fMRI) was used to investigate the representation of sound categories in human auditory cortex. Experiment 1 investigated the representation of prototypical (good) and nonprototypical (bad) examples of a vowel sound. Listening to prototypical examples of a vowel resulted in less auditory cortical activation…
