Coincidence-anticipation accuracy across the life span.

  • Experimental aging research
  • 1 September 1980
TLDR
Findings confirmed age trend in response speed, but only the youngest children performed significantly poorer than the others in coincidence-anticipation accuracy and indicated that older adults showed little directional bias but performed less accurately and more variably than young adults. Expand
Eye Movements While Viewing a Baseball Pitch
Information-processing theory predicts that sport performers gain information from their environment through use of a systematic pattern of eye movements/fixations. Of interest here was theExpand
Altered pattern evoked retinal and cortical potentials associated with human senescence.
Physiologically healthy elderly individuals often exhibit visual deficits which result from age-related changes in both the transmission characteristics of the ocular media and the functionalExpand
Contextual factors and age group differences in coincidence-anticipation performance.
Abstract Age group differences in the direction of anticipatory motor responses may be attributable to the increased susceptibility of young children to contextual factors. That is, theirExpand
Eye movements during coincidence-anticipation performance.

  • Journal of motor behavior
  • 1 December 1977
TLDR
Eye tracking error decreased with increasing age but only the coincidence-anticipation response accuracy of the youngest group appeared to be less accurate than that of the adults, which was major contributor to performance differences with changes in the type of response. Expand
Environmental versus Biological Influences on Gender Differences in the Overarm Throw for Force: Dominant and Nondominant Arm Throws
Both environmental and biological factors have been cited to explain large gender differences in throwing. Because differences are observed as early as three years, some researchers have suggestedExpand
Responses to Speed Changes in Coincidence-Anticipation Judgments after Extended Practice
Abstract Coincidence-anticipation performance has been found to vary with changes in the speed of the task's stimulus. This may be due to bias effects. The present study was designed to investigateExpand
Age, Gender, and Flexibility Differences in Tennis Sewing Among Experienced Older Adults
This study examined tennis serving in older adult tennis players. Twentytwo older adults, divided into younger and older halves, were videotaped serving five "first" serves. Dominant shoulderExpand
Effect of Age on Horizontal Eye Movement Latency
TLDR
For both simple and choice trials, the mean reaction times for younger adults were significantly faster than for older adults, and the distribution of the response times were examined for each age group. Expand
