Dear All,
here is a reminder that Attila Keresztes's Cognitive Seminar Talk with the
title
Hippocampal contributions to memory specificity across the lifespan
is *tomorrow, 5th February at 11:00*
place:* room 206, Institute of Psychology ELTE, 46 Izabella street,
Budapest, 1064*
abstract:
Adaptive learning systems need to meet two complementary and partially
conflicting goals: detecting regularities in the world versus remembering
specific events. The hippocampus (HC) keeps a fine balance between
computations that extract commonalities of incoming information (i.e.
generalization through pattern completion) and computations that enable
encoding of highly similar events into unique representations (i.e. memory
specificity through pattern separation). During early ontogeny, the rapid
and cumulative acquisition of world knowledge through generalization
contrasts slower improvements in the ability to lay down highly specific,
long-lasting episodic memories. At the other end of the lifespan, an early
decrease in memory specificity is paralleled with relatively intact
generalization. In this talk, I will highlight recent behavioral and
neuroimaging evidence suggesting that maturational differences among
subfields within the hippocampus contribute to the lead-lag relation
between generalization and specificity during childhood and adolescence,
and present preliminary results of a study investigating how scenescent
changes within the hippocampus affect specificity and generalization. In
sum, I propose that developmental changes within the hippocampus affect the
fine balance between specificity and generalization across the human
lifespan.
Hope to see you there!
