Frontally Mediated Control Processes Contribute to Source Memory Retrieval
نویسنده
چکیده
Remembering is a cognitively demanding task that requires the strategic selection of information from memory. In this issue of Neuron, Dobbins et al. present functional MRI (fMRI) data that shed insight into the specific, dissociated contributions of frontal regions to remembering.

Functional-anatomic correlates of control processes in memory.
Introduction A central role for control processes in long-term memory is apparent when one considers that there is far more information available in memory than can be accessed at any single moment (Tulving and Pearlstone, 1966; Koriat, 2000). Much as selective attention operates to focus processing on objects in the environment, related control processes are required to constrain and select fr...
متن کاملThe influence of directed attention at encoding on source memory retrieval in the young and old: an ERP study.
Neuroimaging evidence suggests that older adults exhibit deficits in frontally-mediated strategic retrieval processes, such as post-retrieval monitoring. Behavioral research suggests that explicitly directing attention toward source features during encoding may improve source memory for both young and older adults and alleviate age-related source memory impairments, in part, by reducing demands...
متن کاملEvidence for frontally mediated controlled processing differences in older adults.
Advanced aging is associated with slower and less flexible performance on demanding cognitive tasks. Here we used rapid event-related functional magnetic resonance imaging to explore differences between young (n = 65) and older adults (n = 75) during memory retrieval. Methods were optimized to afford exploration of both amplitude and timing differences in neural activity. Although many correlat...
متن کاملIdentifying age-invariant and age-limited mechanisms for enhanced memory performance: Insights from self-referential processing in younger and older adults.
Self-referential processing has been identified as a possible tool for supporting effective encoding processes in the elderly population. However, the importance of self-reference per se, relative to the increase in meaningful elaboration normally associated with self-reference instructions, remains unclear. The present study sought to explore this issue further by examining self-referential en...
متن کاملAge-related Neural Changes during Memory Conjunction Errors
Human behavioral studies demonstrate that healthy aging is often accompanied by increases in memory distortions or errors. Here we used event-related fMRI to examine the neural basis of age-related memory distortions. We used the memory conjunction error paradigm, a laboratory procedure known to elicit high levels of memory errors. For older adults, right parahippocampal gyrus showed significan...
