Document Summary
Combined digit span with the simultaneous performance of a range of other tasks, which were assumed to depend on this limited-capacity system. 2) difficulty accounting for some of the neuropsychological evidence; ex: patient who appeared to have defective stm store, a digit span of two and no recency effect. According to the modal model, the stm store plays a crucial role in transferring information into and out of ltm. This stm deficit holding simultaneously and repeating sequences of up to 8 digits, beyond memory span for many of those tested. Average time to verify the sentences increases systematically with digit load, but not overwhelmingly so. The error rate remained constant at around 5%, regardless of concurrent digit load. The error rate suggests that performance can go ahead quite effectively regardless of concurrent digit load, whereas the processing time data suggest that there is some involvement, although not one of overwhelming magnitude.
