Examined the role of attention in explaining dyadic and triadic joint attention difficulties in autism in three experiments. Found that children with autism were less responsive than developmentally delayed controls in orienting to attention bids and in following a human head-turn cue yet had no difficulty in shifting attention and were faster in…

Tested in two studies 4- to 7-year-olds' face recognition by manipulating the faces' configural and featural information. Found that even with only a single 5-second exposure, most children could use configural and featural cues to make identity judgments. Repeated exposure and feedback improved others' performance. Even proficient memories were…

Several studies have reported that individuals with autism and Asperger's syndrome show a local processing bias on tasks involving features and configurations. This study assessed whether this bias results from differences in the perception of features or a cognitive bias to attend to features in autism as a consequence of a deficit in attending…

The hypothesis that deficits of children with Down syndrome on working memory tasks are more evident the higher the control required and for verbal than visuospatial tasks was tested. Two groups of children, one with Down syndrome, who ranged in age from 7 to 18, and a control group were assessed with batteries of verbal and visuospatial working…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

This article reports on the ability of observers who are sighted and those with low vision to make time-to-collision (TTC) estimations using video. The TTC estimations made by the observers with low vision were comparable to those made by the sighted observers, and both groups made underestimation errors that were similar to those that were…

Children with Specific language Impairment (SLI) have problems with verbal memory, particularly with tasks that have more processing demands. They also have slower speeds of responding for some tasks. To identify the extent to which young children with SLI would differ in performance from age-matched non-impaired children on a set of spatio-visual…

In recent years, latent class models have proven useful for analyzing relationships between measured multiple indicators and covariates of interest. Such models summarize shared features of the multiple indicators as an underlying categorical variable, and the indicators' substantive associations with predictors are built directly and indirectly…

Cognition-related brain responses to meaningful and meaningless figures were registered in 5-year-old kindergarten children who either had been subtyped as being at-risk of developing an L- or P-type dyslexia (LAL versus LAP) or who were not at-risk. While identifying, naming, or categorizing pictures, event-related potentials (ERP) were…

This research examined the use of visual-spatial representation by deaf and hearing students while solving mathematical problems. The connection between spatial skills and success in mathematics performance has long been established in the literature. This study examined the distinction between visual-spatial "schematic" representations that…

Instructional design is a process that is creative, active, iterative and complex; however, many diagrams of instructional design are interpreted as stifling, passive, lock-step and simple because of the visual elements used to model the process. The purpose of this study was to determine the expressed perceptions of the types of flow diagrams…

Naive nonorganic subjects of at least normal intelligence can not simulate brain damage of the type produced by an external blow to the head on the Bender Gestalt test. (Author/DEP)

THE RELATIONSHIP OF AUDITORY-VISUAL AND TACTUAL-VISUAL INTEGRATION TO INTELLIGENCE AND READING ACHIEVEMENT WAS INVESTIGATED. IN ADDITION, THE RELATIONSHIP OF THE TWO INTERSENSORY INTEGRATION TASKS TO EACH OTHER AND TO THE TYPE OF READING ERRORS MADE ON AN ORAL DIAGNOSTIC READING TEST WAS ALSO EXPLORED. THE SAMPLE WAS COMPOSED OF 121 WHITE…
