The days we never forget: Flashbulb memories across the life span in Alzheimer's disease
We examined the frequency, characteristics, and the temporal distribution of flashbulb memories across the life span. To this aim, 28 older adults diagnosed with AD and a matched sample of 29 healthy older controls were probed for flashbulb memories for two historical events from each decade of their lives. They also estimated the subjective degree of reexperiencing for the memories reported. AD participants showed impaired access to flashbulb memories, the frequency of reported memories being lower than for healthy older adults. However, qualitative aspects of AD participants' flashbulb memories were quite similar to thos...

Learned switch readiness via concurrent activation of task sets: Evidence from task specificity and memory load
Mem Cognit. 2024 Apr 16. doi: 10.3758/s13421-024-01560-5. Online ahead of print.ABSTRACTCognitive flexibility increases when switch demands increase. In task switching experiments, repeated pairing of flexibility-demanding situations with specific contexts leads subjects to become more prepared to adapt to changing task demands in those contexts. One form of such upregulated cognitive flexibility has been demonstrated with a list-wide switch probability (LWSP) effect, where switch costs are smaller in lists with frequent switches than in lists with rare switches. According to a recent proposal, the LWSP effect is supported...

Production benefits on encoding are modulated by language experience: Less experience may help
Mem Cognit. 2024 Apr 15. doi: 10.3758/s13421-023-01510-7. Online ahead of print.ABSTRACTSeveral lines of research have shown that performing movements while learning new information aids later retention of that information, compared to learning by perception alone. For instance, articulated words are more accurately remembered than words that are silently read (the production effect). A candidate mechanism for this movement-enhanced encoding, sensorimotor prediction, assumes that acquired sensorimotor associations enable movements to prime associated percepts and hence improve encoding. Yet it is still unknown how the exte...

The effect of value on context and target recollection in memory for truth and falsity
Mem Cognit. 2024 Apr 3. doi: 10.3758/s13421-024-01554-3. Online ahead of print.ABSTRACTMemory for truth and falsity has recently been investigated from the perspective of the dual-recollection theory, showing better context and target recollection for truth than falsity. In this paper, we examine whether these memory effects obtained for true statements are similar to the value effect, whereby true statements are given higher priority in encoding. For this purpose, we implemented value-directed remembering (VDR) into the conjoint-recognition paradigm. In our first experiment, the primary goal was to verify how VDR influenc...
