Prior research has suggested that when recollection fails, individuals can still rely on a sense of familiarity to judge whether something has been experienced before, and the two processes may be dissociable. However, many recognition memory methods index recollection in a binary fashion such that it is treated as an all-or none occurrence. To the contrary, some research suggests that recollection may actually be a variable (i.e., a "some-or-none") process. In the present study, three experiments were conducted to explore the nature of partial recollection using a variation of the recognition without identification procedure (RWI) (Cleary, 2006; Cleary & Greene, 2000; Peynircioglu, 1990). In Experiment 1, I explored the hypothesis that manipulating the amount of perceptual information present at encoding in a recognition task can modulate the likelihood of partial recollection (Parks et al., 2011). In Experiment 2, I examined whether partial recollection responds to word frequency in a manner similar or different than full target recollection or familiarity. In Experiment 3, I explored whether partial recollection, like full target recollection, could also be affected by manipulating degree of target emotionality. In this work, I demonstrate that partial recollection is a distinct, albeit rare, factor in studies of human recognition memory.born digitaldoctoral dissertationsengCopyright and other restrictions may apply.
