Recognition memory is a well-studied example of declarative memory and depends on the integrity of the medial temporal lobe and diencephalic structures (Reed & Squire, 1997; Manns & Squire, 1999). In the VPA task (Fantz, 1964; Fagan, 1970), two identical pictures are presented side by side for a brief viewing period (e.g., 5 sec). After a delay (e.g., 5 minutes; 24 hours), one of the previously viewed pictures is presented along with a new picture. The phenomenon of interest is that individuals will look more at the novel picture than the familiar picture. On the one hand, the task has many of the features of implicit memory. No reference is made to a study episode, and performance appears to have an automatic quality that is reminiscent of habituation. [In fact, the task is commonly used to assess memory in infants who would certainly not yet understand any explicit instructions even if given (Fagan, 1970).] On the other hand however, the direction of gaze is voluntary, and a preference for the new picture could be guided by the same recollective processes that support recognition memory (Manns et al., 2000). More specifically, in humans, Manns and colleagues (2000) found that performance on the VPA task was predictive of subsequent recognition memory performance whereas perceptual priming was unrelated to subsequent recognition memory performance. These results are consistent with the data from lesion studies and suggest that performance on the VPA task measures a form of declarative memory. We found that performance on the visual paired-comparison task was predictive of subsequent recognition memory performance whereas perceptual priming was unrelated to subsequent recognition memory performance. The results are consistent with the data from lesions and suggest that performance on the visual paired-comparison task measures a form of declarative memory.

In contrast to perceptual priming, recognition memory is a well-studied example of declarative memory and depends on the integrity of the medial temporal lobe and diencephalic structures (17, 18). [...]

[...] For example, in the visual paired-comparison task (27, 28), two identical pictures are presented side by side for a brief viewing period (e.g., 5 sec). After a delay (e.g., 5 min), one of the previously viewed pictures is presented along with a new picture. The phenomenon of interest is that individuals will look more at the new picture than the old picture. The question naturally arises: What kind of memory is being exhibited in the visual paired-comparison task? On the one hand, the task has many of the features of implicit memory. No reference is made to a study episode, and performance appears to have an automatic quality that is reminiscent of habituation. On the other hand, the direction of gaze is voluntary, and a preference for the new picture could be guided by the same recollective processes that support recognition memory.
