Auditory stream segregation (or streaming) is a phenomenon in which 2 or more repeating sounds differing in at least 1 acoustic attribute are perceived as 2 or more separate sound sources (i.e., streams). This article selectively reviews psychophysical and computational studies of streaming and comprehensively reviews more recent…

Field trips are ideal for increasing students' experience and perceptions of various organisms and their relationship between the original habitat. However, in general field trips are greatly neglected by teachers and their short-term effects are thought to be questionable. Therefore, we conducted a one-day field trip for both improving students'…

The aim of this study was to determine the contribution of the visual perception and graphic production systems [Van Sommers, P. (1989). "A system for drawing and drawing-related neuropsychology." "Cognitive Neuropsychology," 6, 117-164] to the manifestation of the "Centripetal Execution Principle" (CEP), a graphic…

This research focuses on the relation between color and psychological functioning, specifically, that between red and performance attainment. Red is hypothesized to impair performance on achievement tasks, because red is associated with the danger of failure in achievement contexts and evokes avoidance motivation. Four experiments demonstrate that…

Some visual processing deficits in developmental dyslexia have been attributed to abnormalities in the subcortical M stream and/or the cortical dorsal stream of the visual pathways. The nature of the relationship between these visual deficits and reading is unknown. The purpose of the present article was to characterize reading-related perceptual…

We hypothesized that the right hemisphere would be superior to the left hemisphere in remembering having seen a specific picture before, given its superiority in perceptually encoding specific aspects of visual form. A large set of pictures (N=1500) of animals, human faces, artifacts, landscapes, and art paintings were shown for 2 s in central…

Five and eight year old children were studied to determine at what age children could represent movement in imagery. Two stimuli were presented; the children had to decide if the stimulus was the same or different in shape. (Author/DEP)

A review of significant research on subliminal perception and a summary of evidence for and against it. (Author)

This study investigated the effects of hypnotic susceptibility and of suggestion of direction on four measures of autokinetic movement: the mean number of changes in direction reported per trial, the latency of reported movement, the estimated direction, and the reported magnitude of movement.

Author discussed the nature and objectives of political education today. (Editor/RK)

The study examined the effect of two instructional interventions (equivalence training and functional object use training) as well as practice alone with 21 autistic children (3 to 16 years old) selected for their visual overselectivity. The study had four phases: 1) pretraining in which potential Ss were trained on matching to sample tasks, 2)…

Investigated the discrimination of sibling age and sex roles by second born children (age 5-13), with the focus on changes in discrimination as a function of the child's age and sex, sibling status, sex of sibling, and age spacing between siblings. (DP)

An experiment with monochromatic lights is discussed in terms of the selective effects of wavelength on looking time and pleasantness, comparisons of infant and adult data, and differentiation of the selective effects of color category centers and color category boundaries. (JMB)

Authors compare their model to that of Noton & Stark (1970, 1971), and is found to predict the same behavior but without requiring explicit storage of eye movement commands. (Author)
