A weighted Euclidean distance model is proposed that incorporates a latent class approach (CLASCAL). The contribution to the distance function between two stimuli is per dimension weighted identically by all subjects in the same latent class. A model selection strategy is proposed and illustrated.

Two experiments found that (1) by age 8 months infants perceived that leaning extends their effective reaching space to grasp objects; (2) by 10 months they perceived the effective limits of leaning and reaching; and (3) by 12 months they began to perceive how this space may be extended by a mechanical aid. (MDM)

Infants were tested at 5, 8, and 13 months of age for numerosity perception. Subjects observed displayed figures on a screen moving at constant speed with irregular trajectories and occasional occlusions. Results demonstrated that discrimination of units, and not of characteristic patterns, underlies numerosity perception. (BC)

Examines relationship between results on Attitudes toward Women Scale and free response listing of thoughts in measuring 79 male, 81 female college students' attitudes about women's roles and issues. Both sexes responded more traditionally to Equal Rights Amendment and working mothers and less traditionally to shared household tasks, suggesting…

On a picture vocabulary test, 42 hearing students performed better than 42 hearing-impaired students (ages 10-18) in selecting primary and secondary meanings of multimeaning words. Both groups chose primary meanings more often than secondary ones, and both groups' ability to select two meanings of words did not improve with age. (Author/JDD)

In the two studies reported, three year olds tended to choose mentalistic descriptions more often than behavioral ones to describe people. (PCB)

The addition of idiosyncratic features to individual members of an artificially constructed category enhanced specific item memory among 13 month olds, but not among 10 month olds. Discussion of findings focuses on their theoretical implications and the nature of the age difference. (RH)

This article offers theoretical principles and practical suggestions for teaching physical education to children with autism. It focuses on stimulus overselectivity in the autistic child, the problems it creates for prompting and generalization, and its implications for teaching physical education to this population. (DB)

Presents a brief overview of Gestalt theory. Discusses and illustrates six key principles of Gestalt psychology as they apply to document design and graphics. Presents exercise that students may use to improve their understanding of the principles and develop their document design skills. Distinguishes between Gestalt theory and rhetoric. (RS)

Describes the benefits of infant massage, particularly for babies with deafness who have hearing parents. Steps for giving baby massages are provided, including placing a hand on the baby's stomach and making eye contact, starting with the legs, looking for cues, and communicating with the baby. (CR)

Describes a method of altering auditory input (Altered Auditory Input) and a structured set of listening tasks (Language Webs) for use with children who have language delays or impairments. The parameters of rate, prosody, and pattern of pausing are modified in the Altered Auditory Input (AAI) technique and Language Webs offer redundant,…

Discusses developments in technology that provide high-quality visual access to transition information and multimedia instruction for learners with deafness. Identifies a variety of considerations in using multimedia products and describes the pros and cons of different media in the context of several multimedia projects. (Author/CR)

Reports two sets of lexical priming experiments in which the morphological, semantic, and orthographic relationships between primes and targets are varied in three SOA conditions. Results showed that morphological structure plays a significant role in early visual recognition of English words that is independent of both semantic and orthographic…

Three experiments manipulated 3-month-olds' attention to different components of a training display and assessed the effect on retention. Results suggested that increasing or decreasing attention to an item during encoding produces a corresponding increase or decrease in memorability. Findings were consistent with a levels-of-processing account…

This study examined the influence of time press, specific stimulus, and type of creativity prompt on fluency and flexibility scores of 75 undergraduates. Results suggest that time press has a strong, and typically linear influence on both fluency and flexibility scores. A significant difference across stimuli was observed for flexibility, but not…
