Since the early days of psychology, researchers have investigated whether or not intending to remember information affects subsequent memory performance. The literature contains methodological issues and empirical contradictions, with ambiguous effects. In five experiments, a total of 576 participants viewed a rapid series of pictorial stimuli under either incidental- or intentional-memory conditions. Although the methodology was stringent, intent to remember consistently enhanced recognition memory. Recognition was enhanced even when participants viewed a picture of a human face, of an ape face, or of a bird for as little as 0.5-1.0 sec, with no interstimulus interval between it and the next picture. Rehearsal, depth of processing, and attentional allocation are discussed to explain how people might intentionally encode pictorial information to enhance their subsequent recognition memory performance.
