V. Goffaux and B. Rossion (2006) argued that holistic processing of faces is largely supported by low spatial frequencies (LSFs) but less so by high spatial frequencies (HSFs). We addressed this claim using a sequential matching task with face composites. Observers judged whether the top halves of aligned or misaligned composites were identical.…

This study investigated feature- and dimension-based intertrial effects in visual search for a pop-out target. The 2 prominent theories explaining intertrial effects, priming of pop-out and dimension weighting, both assume that repeating the target from the previous trial facilitates attention shifts to the target, whereas changing the target…

A large body of research has reported visual perception deficits in both people with dyslexia and autistic spectrum disorders. In this study, we compared form and motion coherence detection between a group of adults with high-functioning autism, a group with Asperger's disorder, a group with dyslexia, and a matched control group. It was found that…

Typical adults use predictable scan patterns while observing faces. Some research suggests that people with autism spectrum disorders (ASD) instead attend to eyes less, and perhaps to the mouth more. The current experiment was designed as a direct measure of scan paths that people with and without ASD use when identifying simple and complex…

The preparation of eye or hand movements enhances visual perception at the upcoming movement end position. The spatial location of this influence of action on perception could be determined either by goal selection or by motor planning. We employed a tool use task to dissociate these two alternatives. The instructed goal location was a visual…

A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

This study investigated the effects of sex of perceiver, race of expressor, and mode of presentation of stimuli (Audio/visual, visual/only, audio/only, and still pictures) on perception of emotion. Emotions are most accurately perceived in audio/visual; females were superior in perception of emotions. (JB)

For the forty-second time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Las Vegas, Nevada. The Proceedings of AECT's Convention are published in two volumes. Volume 1 contains 37 papers dealing…

Illustrated by full-page photographs, this book focuses on each of the child's five senses and shows how the senses are interrelated. Activities are suggested to increase the child's sensory awareness. (CS)

Background: Perception disorders are frequently observed in persons with intellectual disability (ID) and their influence on cognition has been discussed. The objective of this study is to clarify the mechanisms behind these alterations by analysing the visual event related potentials early component, the N1 wave, which is related to perception…

Aim: The aim of this study was to determine whether psychosocial stimulation up to the age of 2 years benefits cognition and behaviour at age 6 years in low-birthweight, term-born (LBW-T) children (gestational age greater than or equal to 37wk, birthweight less than 2500g), and to compare LBW-T and normal-birthweight (NBW) children. Method: LBW-T…

Changes in conceptualization and measurement of the verbalizer-visualizer dimension led us to re-examine the hypothesis that students learn best when instructional material matches their cognitive style. First-year psychology university students (n = 41) studied information on three personality theories presented in text only, text+picture, or…

Males traditionally outperform females on measures of both visuospatial ability and science achievement. This experiment directly tests a manipulation designed to compensate for such differences through the presentation of relevant illustrations or animations to support the construction of understanding of a specific scientific phenomenon. Males…

The present study examines coviewing of "Baby Mozart" by 6- to 18-month-old infants and their caregivers under naturalistic conditions. We had two questions. First, extending the method of Barr, Zack, Garcia, and Muentener (Infancy, 13 [2008], 30-56) to a younger population, we asked if age, prior exposure, and caregiver verbal input would predict…
