Abstract: | Diverse outcomes, both facilitative and disruptive, have been reported for the effect of interpolated item recognition tests
on the acquisition of a cognitive skill. We collected data from a repeated set of 12 artificial arithmetic problems, soliciting
compute/retrieve strategy reports after every trial. In one condition, a recognition test was administered after every three
blocks of training. Recognition testing was found to depress retrieve frequencies in both younger and older adults, particularly
for newly acquired items. Pairing training items with similar recognition foils mitigated these effects. This pattern of results
could be explained by assuming that the participants based compute/retrieve decisions on item familiarity or frequency, tracked
across both skill trials and recognition trials, and on a threshold influenced by source confusion. Variations in the threshold
parameter could lead to depressed reports of item retrieval (our findings) or to elevated retrieval decisions, as has been
shown in some other studies. |
