The Effects Of Frequency & Source Of Feedback On Performance Under Goal-Setting Conditions, David Campshure

Masters Theses & Specialist Projects

Feedback and goal setting are both necessary for either to have an effect on performance (Erez, 1977). In the present study two attributes of feedback, frequency and source, were manipulated under goal-setting conditions to examine their effects on performance. It is generally assumed that performance can be enhanced by providing individuals with frequent feedback and by providing them with feedback that originates from a source close to themselves--that is, feedback from the task itself or self-administered feedback. A third variable of interest, subjects' perceived control over the task, was assessed via questionnaires.

Subjects worked on a problem-solving task. Each subject …

Anisms Underlying Improvement Of Peripheral Visual Processing In Older Adults, David Ball

Masters Theses & Specialist Projects

The aim of this project was to examine the effects of perceptual learning, or practice, on the vision of older adults. Previous findings had indicated that older adults have restricted functional visual fields, but that practice in detecting peripheral targets can substantially improve their performance. Two possible explanations for poorer performance in the older age groups were examined: 1) slowed speed of central perceptual processing and 2) attentional deficit problems. Six observers in each of three age groups were tested and trained in performing a peripheral localization task while performing a concurrent central task. A progressive loss in the functional …
