Eye direction detection has been claimed to be intact in autism, but the development of this skill has not been investigated. Eleven children with autism and 11 typically developing children performed a demanding face-to-face eye direction detection task. Younger children with autism demonstrated a deficit in this skill, relative to younger…

Grapheme-color synesthesia, when achromatic digits evoke an experience of a specific color (photisms), has been shown to be consistent, involuntary, and linked with number concept in adults, yet there have been no comparable investigations with children. We present a systematic study of grapheme-color synesthesia in children aged between 7 and 15…

The relationship between rapid automatized naming (RAN) and reading fluency is well documented (see Wolf, M. & Bowers, P.G. (1999). "The double-deficit hypothesis for the 'developmental dyslexias.'" "Journal of Educational Psychology," 91(3), 415-438, for a review), but little is known about which component processes are important in RAN, and why…

Developmental dyslexia is often characterized by a visual deficit, but the nature of this impairment and how it relates to reading ability is disputed ("Brain" 2003; "126": 841-865). In order to investigate this issue, we compared groups of adults with and without dyslexia on the Ternus, visual-search and symbols tasks.…

Developed a multifactor Rasch scale for a visual designs test of artistic judgment and tested the instrument with 462 adult examinees at an aptitude assessment service. The sound measurement properties identified suggest promise for a comprehensive artistic judgment construct. (SLD)

Limits of graphic display design component variation based on cognitive tolerance for imprecision were investigated using compatibility functions. The compatibility function is an empirical definition of a perceptual category representing the grade of membership of an implied physical attribute into a corresponding conceptual category, measuring…

A sample of college students was used to determine whether there was a correlation between Lowenfeld's visual-haptic continuum and Piaget's concrete-formal continuum. Three instruments were administered--a questionnaire, the Successive Perception Test I (Gibson) which identified an individual's location on the visual-haptic continuum, and the…

The visual-auditory integrative ability of 12 language delayed children with nonspecific etiologies was compared with that of 12 normal children matched for age, sex, and IQ. A battery of tests measured auditory-visual integrative ability, visual motor ability, and perception of frequency distorted speech. Significant differences were found…

To determine whether interrelationships existed among visual motor perception, linguistic skills, academic achievement, and the audiological status of deaf children, 199 subjects functioning from dull normal to superior in intelligence (aged 5.6 to 11) were studied. The results of the testing revealed that visual-motor-perceptual dysfunction is…

This bulletin is a compilation of papers dealing with the role of perceptual functions in reading and reading difficulties that were delivered at the 1966-67 Convention of the International Reading Association. Various sections are devoted to discussions of and reports of research on such matters as the auditory and visual modalities in reading,…

Methods for teaching pupils to use their senses to explore colors, shapes, textures, and sounds of the great outdoors are described. Ideas include: (1) having children hug their own special tree; (2) looking for geometric shapes in nature; (3) taking nocturnal nature walks; (4) building a track for racing insects; and (5) collecting objects with…

Five first-hand Web page accounts of unusual sensory perceptual experiences written by persons with high-functioning autism were selected for qualitative analysis. Four core categories emerged: turbulent sensory perceptual experiences; coping mechanisms; enjoyable sensory perceptual experiences; and awareness of being different, suggesting they…

The loss of one sensory modality can lead to a reorganization of the other intact sensory modalities. In the case of individuals who are born profoundly deaf, there is growing evidence of changes in visual functions. Specifically, deaf individuals demonstrate enhanced visual processing in the periphery, and in particular enhanced peripheral visual…

Replies to comments mad by Howe et al. on the current author's original article. The double-anchoring theory of lightness (P. Bressan, 2006b) assumes that any given region belongs to a set of frameworks, created by Gestalt grouping principles, and receives a provisional lightness within each of them; the region's final lightness is a weighted…

The purpose of the present experiment was to compare auditory with visual perception of rhythmic temporal patterns. (Author)
