Human memory testing results. (a–d) The hit rates (eg, the probability of correctly recognizing an old item as old) and false alarm rates (eg, the probability of incorrectly recognizing a new item as old) are shown for each task. For the color task, the hit rate was significantly lower in the anesthesia group. False alarm rates were not different between groups in either task. (e and f) Source recollection performance in the color task was significantly impaired in the anesthesia group.
