Two studies assessed the kinesthetic aftereffect using a wide inducing block with the Petrie measurement procedure and a traditional procedure. The subjects included 76 male and 101 female undergraduates. Aftereffect scores were generally correlated as predicted. (TJH)

During self-motion, the world normally appears stationary. In part, this may be due to reductions in visual motion signals during self-motion. In 8 experiments, the authors used magnitude estimation to characterize changes in visual speed perception as a result of biomechanical self-motion alone (treadmill walking), physical translation alone…

Examined 2-month-old infants' perception of sparse random-dot displays depicting an illusory shape against a background in three experiments in which background texture, luminance cues, and relative motion information were added or deleted. Found that infants preferred novel stimuli in each condition, revealing an early capacity to perceive shape…

The validity of the Kinesthetic Aftereffect (KAE) as a measure of personality has been criticized because of KAE's poor test-retest reliability. However, systematic bias effects render KA E retest sessions invalid and make test-retest reliability an inappropriate measure of KAE's true reliability. (Author/CTM)

Paper presented at the 48th Annual Conference of the American Occupational Therapy Association, Portland, Oregon, October 20-26, 1968. Research supported by U.S. Public Health Service Grant Number FR05357.

A study investigated the recall of terminal location and distance of both preselected and constrained movements. Systematic alteration of the magnitude and direction of the starting position for recall movements revealed that the distance moved significantly interfered with the recall of the terminal location, but that distance was usually…

Examined critical features of tactile and kinesthetic processes by administering 8 traditional psychometric instruments and 14 measures of tactile and kinesthetic perceptual processes to 116 female college students in Australia. Results show, as is consistent with earlier findings, that visual-spatial processes are difficult to separate from…

Drop jumping has previously been used to measure fast stretch shorten cycle (SSC) ability and stretch load tolerance. To the knowledge of these authors a test does not exist to achieve this in the horizontal direction. The purpose of this study therefore was to estimate the reliability of a new unilateral horizontal leg power test to assess these…

Age-related characteristics of children's short-term retention of kinesthetic movement information were examined in this study. Three age levels (6-, 8-, and 10-year old children) were tested for recall of preselected location movements on a linear slide apparatus. Immediate and delayed recall were used in 16 trials. The results indicate that…

The purpose of this study was to explore how children use location and distance cues to reproduce movements as compared with adults. Subjects were three groups of children, aged 6, 8, and 10, and one group of adults. A linear slide was used by the blindfolded subjects to indicate one of two experimenter-defined stops. Distance and location were…

Discusses the size-weight illusion that occurs when a person lifts two equal-weight objects differing in size and perceives the larger object as lighter than the small object. Describes several inexpensive techniques for demonstrating the size-weight illusion and reviews some relevant issues concerning this phenomena. (MJP)

It may be possible, using assessments of motor and perceptual skills which are largely independent of ethnic and educational background, to admit to the military individuals who would be rejected on the basis of their paper-and-pencil test scores, but who through their performance on non-verbal measures, can be identified as highly likely to…

Investigated the relationship between Vividness of Movement Imagery Questionnaire scores and kinesthetic acuity--the sense of body position and movement--among 10- and 14-year-olds. Found that in the older group, those with high levels of visual movement imagery performed better on measures of kinesthetic acuity; no such effect was found for…
