Abstract
The purpose of the present experiment was to determine if mixed letter case (e.g., MiXeD cAsE) and stimulus degradation (masking produced by overprinted backslash characters) interact in a word naming task. A 2 ×2 factorial design was used with 26 college students in a list pronunciation format. Both variables had a significant effect on pronunciation time and on errors. Additionally, mixed case and masking interacted in an overadditive fashion on both dependent variable measures. The data were interpreted as support for a model of human information processing in which both mixed case and masking affect the feature-extraction stage of processing.
