The impact of working memory testing on long-term associative memory.

The long-term fate of to-be-remembered information depends in part on the conditions of initial learning, including mental operations engaged via working memory. However, the mechanistic role of working memory (WM) processes in subsequent episodic memory (EM) remains unclear. Does re-exposure to word-pairs during WM recognition testing improve EM for those associations? Are benefits from WM re-exposure greater after an opportunity for retrieval practice compared to mere re-exposure to the memoranda? These questions are addressed in three experiments (N = 460) designed to assess whether WM-based recognition testing benefits long-term associative memory relative to WM-based restudying.

Cognitive aging and the life course: A new look at the Scaffolding theory.

Our understanding of human neurocognitive aging, its developmental roots, and life course influences has been transformed by brain imaging technologies, increasing availability of longitudinal data sets, and analytic advances. The Scaffolding Theory of Aging and Cognition is a life course model, proposed originally in 2009, featuring adaptivity and compensatory potential as lifelong mechanisms for meeting neurocognitive challenges posed by the environment and by developing or declining brain circuitry. Here, we review the scaffolding theory in relation to new evidence addressing when during the life course potentially enriching and depleting factors exert their effects on brain health and scaffolding, and we consider the implications for separable, and potentially reciprocal, influences on the level of cognitive function and the rate of decline in later life.

Impacts of spaceflight experience on human brain structure.

Spaceflight induces widespread changes in human brain morphology. It is unclear if these brain changes differ with varying mission duration or spaceflight experience history (i.e.

Biden or Trump? Working memory for emotion predicts the ability to forecast future feelings.

Affective forecasting-the ability to predict how different outcomes will make us feel-is a crucial aspect of making optimal decisions. Recent laboratory evidence suggests that working memory for emotion is a basic psychological mechanism underlying forecasting ability: Individual differences in affective working memory predict how accurately people can forecast their future feelings whereas measures of "cognitive" working memory do not. Here, we demonstrate that this selective relationship between affective forecasting and affective working memory generalizes to forecasted feelings about a major real-world event.
