Remembering the Details: Processes of Recognition Memory

Walking along the street you pass a person that looks very familiar, but you can’t put your finger on where, who, or why you know this person. All of a sudden, you remember that is Bob from the gym. There is a debate in the recognition memory literature on whether or not the two ways an event may be remembered described in the previous sentences (based on familiarity without details or based on recollection of details) are due to the same memory process in the brain or two separate processes. In the current study, I will investigate individual differences in young adults (18-30 years of age) by administering a yes/no item recognition task while monitoring their event-related potentials (ERPs) with an EEG cap. ERPs are electrical potentials associated with specific sensory, motor, and cognitive events within the brain. I will examine memory performance in high functioning young adults versus low functioning young adults as defined by their performance on a battery of neuropsychological tests associated with the frontal and medial-temporal lobes. The comparison of these two groups offers insight into how the processing of memory occurs. I will investigate the proportion of recollection and familiarity responses on the task given between the two groups (high and low functioning) along with the ERP activity associated with the frontal and medial-temporal lobes during the participants responses to the item recollection task.
