Using a gaze-following task, the authors assessed whether self-experience with the view-obstructing properties of blindfolds influenced infants' understanding of this effect in others. In Experiment 1, 12-month-olds provided with blindfold self-experience behaved as though they understood that a person wearing a blindfold cannot see. When a…

A critical question in Cognitive Science concerns how knowledge of specific domains emerges during development. Here we examined how limitations of the visual system during the first days of life may shape subsequent development of face processing abilities. By manipulating the bands of spatial frequencies of face images, we investigated what is…

The own-race advantage in face recognition has been hypothesized as being due to a superiority in the processing of configural information for own-race faces. Here we examined the contributions of both configural and component processing to the own-race advantage. We recruited 48 Caucasian participants in Australia and 48 Chinese participants in…

Normal observers demonstrate a bias to process the left sides of faces during perceptual judgments about identity or emotion. This effect suggests a right cerebral hemisphere processing bias. To test the role of the right hemisphere and the involvement of configural processing underlying this effect, young and older control observers and patients…

This study examined whether color perception is atypical in children with autism. In experiment 1, accuracy of color memory and search was compared for children with autism and typically developing children matched on age and non-verbal cognitive ability. Children with autism were significantly less accurate at color memory and search than…

With standardized English Language Arts exams on the horizon, the author thought a game of Antonyms would provide not only a quick language arts activity for her sixth graders, but also a nice segue to an art lesson in contrast. In this article, she describes a project, a simple saucer on a pedestal base, which required students to demonstrate…

Individuals with autism show a complex profile of differences in imitative ability, including a general deficit in precision of imitating another's actions and special difficulty in imitating nonmeaningful gestures relative to meaningful actions on objects. Given that they also show atypical patterns of visual attention when observing social…

Four dual-task experiments examined visuospatial, articulatory, and central executive working memory involvement during the development and application of spatial mental models. In Experiments 1 and 2 participants read route and survey spatial descriptions while undertaking one of four secondary tasks targeting working memory components.…

Two experiments investigated infants' ability to localize tactile sensations in peripersonal space. Infants aged 10 months (Experiment 1) and 6.5 months (Experiment 2) were presented with vibrotactile stimuli unpredictably to either hand while they adopted either a crossed- or uncrossed-hands posture. At 6.5 months, infants' responses were…

A rapid serial visual presentation (RSVP) technique was used to investigate the role of the nature of processing carried out on targets in the Lag-1 sparing phenomenon. Lag-1 sparing refers to a higher accuracy in the task associated with the 2nd target when the 2 targets are immediately successive in the RSVP stream relative to when there are 1…

The authors investigated the calibration of reach distance by gradually distorting the haptic feedback obtained when participants grasped visible target objects. The authors found that the modified relationship between visually specified distance and reach distance could be captured by a straight-line mapping function. Thus, the relation could be…

Use of the Slingerland Screening Tests to detect auditory, visual, and kinesthetic handicaps among children in the classroom is advocated in reference to implementation of Tennessee Public Law 839 which mandates educational services for handicapped persons 4 to 20 years of age. (JC)

Lowenfeld (1945) developed a series of six instruments which could be used to identify perceptual abilities. For this study, the visually oriented person was defined as the objective viewer of the environment, while the haptic person was defined as a person who uses the eyes only when forced to do so and relates to his environment subjectively. He…

PERCEPTION IS DEFINED AS THE MEANINGFUL RESPONSE TO THE VISUAL OR ORAL SIGNAL WHICH IS UNIVERSALLY REFERRED TO AS WORDS. PERCEPTION INCLUDES THE AROUSAL OF MEANING AND IS A CONSCIOUSNESS OR AN AWARENESS OF THE EXPERIENCES ELICITED BY THESE VISUAL OR ORAL SIGNALS. IMPROVING WORD PERCEPTION INVOLVES AT LEAST THE FOLLOWING THREE PROCESSES WHICH ARE…

A STUDY WAS CONDUCTED TO DETERMINE WHETHER AUDIOVISUAL PERCEPTUAL ABILITY CAN ACCOUNT FOR READING ACHIEVEMENT. SUBJECTS WERE 120 PUPILS SELECTED RANDOMLY FROM 38 SCHOOLS IN ILLINOIS. PUPILS WERE IN GRADES 2, 4, AND 6. MEASURES OF VISUAL PERCEPTION, AUDITORY PERCEPTION, VISUAL-AUDITORY SHIFTING PERCEPTION, INTELLIGENCE, SOCIOECONOMIC STATUS, AND…
