Abstract
Correct report of the capital target letters “A” and “T” was determined with a pattern mask for conditions of high and low target energy under light and dark adaptation. The level of target energy interacted with the adaptation state. With low energy targets, target report was highest under dark adaptation. With high energy targets, target report was highest under light adaptation. These findings were incompatible with Scharf & Fuld’s (1972) hypothesis of the influence of adaptation state on masking by a visual pattern.
