Ten right‐handed, right‐eye dominant subjects memorized conventional digits projected successively in pairs, one digit to each eye. Each worked under five different binocular viewing conditions; two delay periods (rehearsal times) were used between successive pairs of digits. Performance was analysed in terms of speed and accuracy of recall of digits projected to each eye. Results suggest a central integrating mechanism of limited capacity in recall, and that temporal grouping of responses is symptomatic of this limited capacity when the mechanism is taxed.
