An event-related potential study of recognition memory with and without retrieval of source

Abstract

Event-related potentials (ERPs) were recorded during the test phase of a recognition memory task in two experiments. In both experiments subjects made initial old/new judgements to visually presented words, and for words judged old, indicated in which of two voices (male/female) the words had been heard at study. In the second experiment only subjects had the option to signal that they were uncertain about the status of a test word. Two positive-going ERP effects differentiated the ERPs evoked by correctly recognized old words from those evoked by words correctly judged new. The two effects differed in their scalp topography and time course, and were both of greater magnitude in the ERPs evoked by recognized words for which a correct voice judgement was made. The findings are consistent with the view that multiple neural systems underlie the ability to recognize an item and to recall its study context. However, the findings offer little support for the view, articulated in certain 'dual-process' models of recognition memory, that recognition judgements with and without retrieval of study context depend upon qualitatively different memory processes or systems.

Use it or lose it? SES mitigates age-related decline in a recency/recognition task

“…An item's source can be defined as any of a number of contextual features that accompany the occurrence of an event, including perceptual (e.g., speaker's gender [74]; picture's color [14] and temporal (e.g., sequential list in which the item occurred [67]) characteristics. Memory for contextual features, especially spatiotemporal aspects, appears to be particular vulnerable to increasing age [60], compared to simple recognition of the item as "old" (item memory).…”

“…During more typical source memory paradigms, distinct physical item features identify the two sources (e.g. color [14] or speaker's voice [74]). However, in recency memory paradigms such distinct physical features are not necessarily available as the temporal order of presentation is the critical piece of information that needs to be retrieved.…”

Multiple synergistic effects of emotion and memory on proactive processes leading to scene recognition

“…These results also confirmed that participants correctly 361 attended to the actual emotional content of the scenes throughout the experiment. (Curran 391 and Cleary, 2003;Curran and Doyle, 2011;Sanquist et al, 1980;Wilding and Rugg, 1996;392 Wilding et al, 1995), and provide converging evidence that our short-term memory manipulation 393 was successful. 394…”

“…These results are 555 consistent with previous studies (Curran and Cleary, 2003;Curran and Doyle, 2011;Weymar et 556 al., 2009;Wilding and Rugg, 1996;Wilding et al, 1995), and provide converging evidence that 557 our short-term memory manipulation was successful. However, neither the main effect of 558 emotion nor the emotion x memory interaction were significant (all ps > .05), indicating 559 comparable old/new effects for neutral and emotional scenes.…”
