An Iconic Comparison of Photographs and the Live Television Screen in Visual Diagnostic Ability.
Hofer, Jarrel
This study focused on five major activities: (1) developing an achievement test to measure visual diagnostic ability of television service technicians, (2) assessing the independence of the dimension of visual diagnostic ability, (3) comparing the iconic equivalence of photographs with motion cues and live screen presentations of defective television pictures for testing purposes, (4) ascertaining if static and dynamic tests are measures of a single dimension, and (5) assessing the reliability of the two tests. Static and dynamic tests were administered to 89 students who were completing 1-year programs in radio-television servicing, and to 24 radio-television technicians. A panel of radio-television instructors and technicians wrote the questions and judged the appropriateness of items for the test. Several hypotheses were analyzed as results of the tests. A copy of the directions for the tests, and computer printouts are appended. (AG)
