| Descripción: | The nature of the rehearsal mechanism that supports short-term memory span (STM), and the role of lexical and semantic knowledge in list recall was evaluated. Forty university students (aged 17-29 years) recalled lists of words varied in syllable-length (SL), articulatory duration (AD), phonological similarity (PS), semantic relatedness (SR) and frequency of occurrence (FO). Auditory and visual presentation, vocal and picture-pointing recall, and concurrent articulation conditions were included. Nonword recall was evaluated using stimuli varied in SL and PS was also evaluated using a repetition task. Word length effects were found for word stimuli varied in SL but were absent or reversed for stimuli varied in AD. A non-articulatory basis for rehearsal is suggested. The influence of long-term semantic and lexical knowledge in recall is inconclusive due to a lack of SR. Nonword repetition ability reflects STM capacity in adult subjects and correlates with other measures of STM span. |
