Durability of retrieval-induced forgetting: Effects of different practice schedules.

If retrieval-induced forgetting (RIF) is to play a role in the formation of collective memories, it should be long lasting. Although several studies have found that RIF is short-lived, there is other evidence to suggest that repeated selective practice schedules with a temporal gap between each practice trial may increase the durability of RIF. We tested this possibility in three experiments, focusing on socially shared retrieval-induced forgetting (SSRIF).

ASO-mediated knockdown of GPNMB in mutant- and -deficient peripheral myeloid cells disrupts lysosomal function and immune responses.

Background: Increases in GPNMB are detectable in FTD- cerebrospinal fluid (CSF) and post-mortem brain, and brains of aged -deficient mice. Although no upregulation of GPNMB is observed in the brains of young -deficient mice, peripheral immune cells of these mice do exhibit this increase in GPNMB. Importantly, the functional significance of GPNMB upregulation in progranulin-deficient states is currently unknown.

Malleable national collective memories among Black and White Americans.

How do groups remember their shared past? Are there individual differences within a group? How easy is it to change collective memories? The present article addresses these questions by focusing on differences within national subgroups, exploring how national collective memories might differ for Black and White Americans, how individual differences and external influences might moderate or alter any differences, and the temporal extent of any changes that might occur due to external influences. Across four studies, participants were asked to identify the five "most important" events in U.S.

When the personal and the collective intersects: Memory, future thinking, and perceived agency during the COVID-19 pandemic.

Do collective crises have an impact on the characteristics of mental time travel for individuals and collectives? The COVID-19 pandemic provides a unique context to address this question due to the intersection it created between the personal and the collective domains. In two studies ( = 273), we examined the valence and perceived agency involved in memory and future thinking for personal and collective domains. The second study also included a longitudinal component with 43 participants completing both studies.
