Large auditory and small visual effects in the recall of consonant letters

Eighty-six adults serially recalled lists of visually presented consonant letters similar in auditory or visual features or dissimilar in both feature sets. There were significantly more errors at every auditory list position than at the corresponding visual and neutral list positions, which did not themselves differ. There was a positive correlation between the tendency toward phonetic coding and overall performance, with 75 subjects making more errors on the auditory list than either of the other lists. The eight subjects who made more errors on the visual list showed poor performance in the recall of all lists. Factors governing the perceivability of stimuli apparently do not continue to operate significantly in controlling their recallability, at least in the case of veridical visual input.
