Combined Lesions

The dorsal bank of the superior temporal sulcus (STSd) bears anatomical relations similar to those of perirhinal cortex, an area critical for visual recognition memory. To examine whether STSd makes a similar contribution to visual recognition memory, performance on visual delayed nonmatching-to-sample (DNMS) was assessed in rhesus monkeys with combined or separate ablations of the perirhinal cortex and STSd as well as in unoperated controls. Consistent with previous findings, ablations of perirhinal cortex produced deficits nearly as severe as that found after rhinal (i.e., entorhinal plus perirhinal) cortex lesions. However, combined lesions of perirhinal cortex and STSd produced a deficit no greater than that produced by perirhinal cortex ablation alone, and lesions of STSd alone were without effect on DNMS. We conclude that STSd is not critically involved in visual recognition memory.

Increased Susceptibility

Two series of experiments investigated short-term visual recognition memory in pigeons following lesions of the hyperstriatal complex; the first series used a choice technique, the second, a single-key go/no go technique. The results of the two series agreed, first, in finding impaired performance in hyperstriatal birds at long but not at short inter-trial intervals, and, second, in obtaining no evidence of differential rates of decay of traces in hyperstriatal and control subjects. A final experiment confirmed that the hyperstriatal birds were, as expected from previous work, impaired on reversals of colour and position discriminations. It is tentatively suggested that deficits following hyperstriatal damage in both recognition and reversal performance may be understood as being the consequence of an increased susceptibility to frustrating events in hyperstriatal subjects.

Recognition Technique

Recognition memory for lists of items was investigated in pigeons using a YES-NO recognition technique. Experiment I showed that increasing the exposure duration of the first item of a two-item list improved recognition for that item without impairing recognition of the second item. Experiment II showed that decreasing the inter-trial interval had no effect on correct YES responses but significantly increased the number of false YES responses. Experiment III showed that recognition for the last two items of a three-item list was no poorer than that for lists of only two items. Experiment IV showed that increasing the delay between presentation and test of a two-item list (from 0·25-1 s) had a more disruptive effect on recognition for the second than for the first item. The data from these four experiments support a model proposed by Roberts and Grant, according to which memory traces are independent, and decay as a negatively accelerated function of time. Experiments V, VI, and VII investigated recognition for lists of three, four, and five items, and found no evidence for a primacy effect, performance being a linear function of time since sample offset.
