Investigates the psychological representation of visual-gestural languages from a cross-linguistic perspective. The perception of signers of American and Chinese Sign Languages is analyzed. (27 references) (Author/VWL)

Focuses on investigations of infant sensation and perception over the past 25 years. Describes the knowledge base concerning the sensory and perceptual world of the infant in the mid-1960s. Methodological highlights in the study of vision and audition are covered. (RJC)

Fencers should be taught to discipline their eyes to focus on the opponent's hand. The rationale for this strategy as well as drills to develop "hand watching" skills are presented in this article. (IAH)

How the dual-task interference effects, observed when subjects attempted to simultaneously perform two simple tasks, are related to capacity limitations in perceptual processing of complex visual displays was studied. Results for a total of 110 undergraduates in 6 experiments support a 2-component theory of divided attention. (SLD)

Examines the ability to differentiate appearance-reality and Level Two perspective-taking in tactile modality among a total of 92 children aged two-four years in three studies. The results indicate that three-year-olds find tactile appearance-reality and Level Two perspective-taking tasks easier than visual ones. (RJC)

Analyzes the visual and verbal content of the 1984 televised debates between Walter Mondale and Ronald Reagan. Asserts that the televised depiction of the debates visually structured portions of them in a manner inconsistent with their verbal content. Focuses on clash, when candidates engaged in arguments of attack or defense. (MS)

Visual behavior of infants was assessed with multiple discrimination tasks week to week from four to seven months of age. Task to task reliability was low, but attentional averages from week to week were reliable. Generally, infants with shorter fixations showed more novelty preferences, and infants' shift rate improved with age. (SKC)

Hearing-impaired speechreaders focus on visual characteristics of speech sounds, termed visemes. Determination of viseme groupings requires consideration of the sound's visible characteristics and articulatory differences of speakers. Coarticulation effects that modify viseme groups include vowel-context effects on consonant viseme groupings,…

Four experiments examined how perception affects delayed recognition, visual pop out, and memory reactivation (priming) in six month olds. Infants discriminated cues differing in spatial arrangement or number of primitive perceptual units (textons) in a delayed recognition task and exhibited adultlike visual pop-out effects in a priming task. (MDM)

Studied 4- to 10-year-olds' familiarity judgments of peers. Found that, contrary to adults, external facial features were key. Also found that the switch to adult recognition pattern takes place after the ninth year. (ETB)

Results of a study involving 15 mentally retarded and 15 nonretarded control subjects matched for mental age suggest that some low-level aspects of person-related (and probably object-related) perception may not involve the same high-level symbolic functions typically employed in intelligence-quotient related functions. (SLD)

Two experiments examined children's ability to use lengths of lines on a page to show orientations of object surfaces. Found that five- and six-year olds are more reluctant to depart from actual object proportions than seven- and eight-year olds, but children in both age groups can foreshorten line lengths to indicate surfaces receding from a…

This study compared speech intelligibility for sentences spoken either conversationally or in a clear manner under three conditions: auditory only, visual only, and audiovisually. Overall, in each condition, speech intelligibility improved significantly for the tokens of clear speech. Some interaction between speaker and manner of speech was…

In two experiments, preschool children and adults were asked to judge which way an equilateral triangle was pointing under several contextual conditions. Results indicated that children and adults attended to both global and local levels of a pattern. (BC)

The development of visual orienting to a cued target on the part of practicing and nonpracticing tennis players aged 13, 16, and 25 years was examined. Results indicated that practicers were not faster than nonpracticers in processing visual information and that subjects of all ages oriented attention voluntarily to cued locations. (LB)
