Abstract:

The effect of magnification on a a task requiring recognition of five-letter words with fragment strokes, words with intact strokes being used as controls, and b a task requiring estimation of the relative numerousness of two types of symbols in an array, was investigated. Magnification was found 1 to have no effect on recognition of words with intact strokes, 2 to impair recognition of words with fragmented strokes, and 3 to improve performance on the estimation of symbols. These results, in conjunction with those presented in a previous report on still other tasks, demonstrate that the effect of magnification may vary with the task on the basis of visual-perceptual factors alone, when instrumental factors are so far as possible ruled out.
