Videotaped productions of isolated American Sign Language signs or sentences were presented at speeds of two to six times normal. Results indicated a breakdown in intelligibility at around 2.5 to 3 times the normal rate. Results are similar to those found for auditory reception of time-compressed speech suggesting a modality-independent limit to…

Investigated visual word recognition of first- through fifth-graders. Found that the "viewing position effect" typically seen in skilled readers and visual field asymmetries in recognizing individual letters in words emerged early at the end of the first year of reading instruction. Noted that findings support the view that basic reading…

This study, with 53 Mexican-American infants, found that five predictors accounted for approximately 35 percent of the variance in receptive language at 12 and 22 months with average parental generation from Mexico (acculturation) and infant visual recognition memory accounting for 14 and 15 percent of the variance, respectively. No predictors…

Three experiments examined vision's role in infants' grasping of horizontally and vertically oriented rods. Found that infants differentially oriented their hand regardless of lighting and similar to control conditions where they could see rod and hand throughout reach. Findings suggest that infants may use current sight of object's orientation or…

Explains that in order for students to understand statistics, they must develop their spatial and visual skills for manipulating numerical data. Describes the use of an inexpensive, low-tech teaching device that is constructed of modeling clay and cardboard in order to overcome this visual barrier when teaching a blind student statistical…

Discusses using visual representations of children to help pre- and in-service teachers reconsider the ways they, as adults, relate to children. Focuses on historical depictions of children, images of children from today, and the photographs Anne Geddes. (CMK)

Focuses on three devices (plan, analysis, and context) with which one can consider electronic mail. States that the inequality in "message contexts" (social, mental, and physical) is the problem in electronic mail communication. Offers implications for using semiotics with visual culture in education. (CMK)

Children diagnosed with Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) and Asperger Syndrome (AS) may be characterised by a similar perceptual focus on details as children with autistic disorder (AD). This was tested by analysing their performance in a visuoperceptual task [the Children's Embedded Figure Test (CEFT)] and a…

Visual perception may be a developmental prerequisite to some types of social understanding. The ability to perceive social information given visual motion appears to develop early. However, children with autism have profound deficits in social cognitive function and may fail to see social motion in the same way that typically developing children…

Recent research has found that the acquisition of theory of mind (ToM) is delayed in children with specific language impairment (SLI). The present study used a battery of ToM and visual perspective taking (VPT) tasks to investigate whether the delayed acquisition of ToM in children with SLI is associated with delayed VPT development. Harris'…

Configural visual abilities in thirteen children with Williams syndrome (WS) compared to 13 children matched on mental age and 13 children matched on chronological age. Configural abilities were tested through four tasks (1) Silhouette (2) Fragmented (3) Mooney and (4) overlapping figures. In the first three tasks, it was necessary to take into…

This study examines basic number processing (subitizing, automaticity, and magnitude representation) as the possible underpinning of mathematical difficulties often evidenced in deaf adults. Hearing and deaf participants completed tasks to assess the automaticity with which magnitude information was activated and retrieved from long-term memory…

When learning basic color vocabulary, young children show a selective delay in the acquisition of brown and gray relative to other basic color terms. In this study, we first establish the robustness of this finding and then investigate the extent to which perception, language, and color preference may influence color conceptualization.…

Previous research with both brain-damaged and neurologically intact populations has demonstrated that the right cerebral hemisphere (RH) is superior to the left cerebral hemisphere (LH) at detecting anomalies (or incongruities) in objects (Ramachandran, 1995; Smith, Tays, Dixon, & Bulman-Fleming, 2002). The current research assesses whether the RH…

This study examined the effect of incorporating a visuo-haptic and haptic (tactual-kinaesthetic) exploration of letters in a training designed to develop phonemic awareness, knowledge of letters and letter/sound correspondences, on 5-year-old children's understanding and use of the alphabetic principle. Three interventions, which differed in the…
