In each of the six experiments, participants studied a list of random words under full attention, and recalled them while performing a distracting task presented visually on a computer. Previous research suggested that divided attention (DA) during retrieval disrupts free recall for words if the distracting task also involves memory for verbal material (Fernandes & Moscovitch, 2000). The purpose of the present work was to determine more precisely which factor(s) modulated this effect, and influence retrieval success. In the first experiment I found that verbal distracting tasks, that required animacy or syllable decisions to words, produced large interference on memory. Experiments 2 and 3 showed that phonemic decisions about nonsense-words produced a similarly large interference effect on memory, that was larger than semantic decisions or size-estimations about pictures of objects. These findings support the component-process model of memory, which suggests that retrieval is largely disrupted only when there is competition for a common representational system. In the next set of experiments an alternative, reduced-resource, account of interference from DA at retrieval is considered by comparing the performance of young and old adults under DA conditions. A word-animacy distracting task interfered substantially with retrieval, but the size of the effect was not amplified in old compared to young adults. Dividing attention using an odd-digit task did not produce as large an effect, in either group. Finally, the contribution of the frontal and temporal lobes to interference effects on memory were examined. Elderly participants were divided pre-experimentally into 4 groups, determined by their scores on measures of frontal and temporal lobe function, derived from neuropsychological testing. Large interference effects on memory were produced by the animacy, but not the odd-digit distracting task. The pattern and magnitude of interference effects did not differ depending on level of temporal or frontal function. These results do not support the hypothesis that effects of DA at retrieval are due to a reduction in general processing resources, attentional capacity, or competition for memory structures in the temporal lobe.

Available in PDF, EPUB and Kindle. Book excerpt: In Study 1, a general slowing of responses was found following stop signal trials. This preliminary finding was elaborated on in Study 2, Experiment 1, which established a baseline measure of repetition after-effects. In line with previous findings, responses were delayed following successful inhibition, but only when the stimulus was repeated (repetition after-effects). Previous studies have shown that response latency is increased when expectancy is violated. However, expectancy takes time to develop and becomes increasingly likely as the interval between trials increases. In Study 2, Experiment 2, it was hypothesised that repetition after-effects result from a systematic timing difference between trials in the stop signal task. In a typical stop signal task, the interval between trials is 1000 ms longer following inhibition. Repetition after-effects were still observed in Study 2, Experiment 2, despite the use of shorter RSIs following stop signal trials. In Study 2, Experiment 3 stimulus expectancy was manipulated directly by increasing the relative frequency of stimulus repetition from 50 percent to 70 percent. This resulted in a repetition benefit for consecutive responses (when the previous trial required a response) however, repetition after-effects were still observed after both successful and failed inhibition. Taken together, the findings of Study 2, Experiments 2 and 3 suggest that repetition after-effects do not result from expectancy behavior. In Study 2, Experiment 4, subjects responded to a single stimulus which did not require identification for successful task performance. In this situation, stimulus attention was expected to be minimal, thus reducing the likelihood of stimulus-goal retrieval. Repetition after-effects were absent in this experiment. This finding is consistent with the stimulus-goal retrieval explanation of repetition after-effects; given that stimulus-goal retrieval was less likely in this situation. Finally, Study 3 investigated the neural correlates of repetition after-effects. EEG data obtained during the stop signal task was used to generate event related potentials (ERP). A selective increase in activity was found on repetition after-effect trials. The timing and location of this increase is consistent with a stimulus-goal retrieval explanation of repetition after-effects. In conclusion, the results from the present thesis do not support the hypothesis that violation of expectancy underlies repetition after-effects of response inhibition. Behavioural and ERP data suggest that repetition after-effects result from interference caused by episodic memory retrieval.
