| Abstract: |
Tests of paced serial addition are used to detect diminished information-processing capacity. Nonetheless, performance might be influenced by modality-specific interference or by variables that specifically affect numerical processing. In a series of three experiments with normal adults, we manipulated, respectively, the modality in which addends were presented, the modality in which responses were produced, and the format in which visual addends were displayed. Performance was enhanced when stimuli were presented visually and when responses were made manually. When visual addends were used, Arabic numerals were processed more effectively than number words. Thus, performance was influenced by modality-specific interference and by presentation format. We conclude that paced serial addition tasks may not provide a pure measure of general information-processing capacity. [ABSTRACT FROM AUTHOR] |
