Does intending to remember information enhance the subsequent remembering of it? If intending to remember information does improve memory, how quickly can attentional or working memory resources be allocated to enhance long-term remembering? Interestingly, the Latin origin of the words intend and attend is intendere, which is translated as "to direct one's attention." In the present experiments, the basic manipulation is that some people encode information without awareness that a memory test will follow (henceforth, incidental memory or incidental condition), whereas other people encode the same information with awareness that a memory test will follow (henceforth, intentional memory or intentional condition). Following the presentation of a series of pictorial stimuli, recognition memory was tested.
Early StudiesScientific studies of the effects of incidental versus intentional memory date to the early days of experimental psychology (Meumann, 1913;Shellow, 1923). (The near-synonymous terms incidental learning and intentional learning usually refer to conditions in studies of the rate at which people acquire a perceptual motor skill or a verbal learning task.) During the 1950s and 1960s, research sometimes revealed positive effects of intent to remember on memory performance (e.g., Neimark & Saltzman, 1953;Postman & Phillips, 1954;Saltzman & Atkinson, 1954;Saltzman & Carterette, 1959). However, as Saltzman (1953) noted, many studies contained a serious confounding: "In the previous studies, . . . the incidental learners were not given instructions to learn, but were required to perform [an] orienting task. The intentional learners . . . were given instructions to learn, but were not required to perform [an] orienting task" (p. 596).Eagle and Leiter (1964) found an interaction between memory condition and type of memory test. Participants heard a series of 36 words at about a 4-sec rate; this was followed by a recall test and, subsequently, by a recognition test. In one condition, the participants were told simply to try to remember the words for a recall test. In two other conditions, the participants performed an orienting task (indicating whether each presented word was a noun, a verb, or an adjective), with some participants in an incidental condition and some in an intentional condition. Participants who performed the orienting task showed no effect of intent to remember on either recall tests or recognition tests. However, there was an interesting interaction: In comparison with participants in the orienting-task conditions, participants in the intentionalmemory condition (who performed no orienting task) recalled more words ( p .001, d 0.72) but recognized fewer words ( p .001, d 0.85). 1 This finding suggests that intent to remember may facilitate recall but impair recognition memory; however, this interaction could have resulted from the fact that the participants in the intentional condition expected a recall test. Estes and Da Polito (1967) reported similar findings, although their procedure confou...
