Background: Language and memory impairments affect everyday interactions between individuals with dementia and their communication partners. Impaired topic management, which compromises individuals' construction of relevant, meaningful discourse, is commonly reported amongst individuals with dementia. Currently, limited empirical evidence…

Purpose: The purpose of this article is to review and discuss theories of working memory with special attention to their relevance to language processing. Method: We begin with an overview of the concept of working memory itself and review some of the major theories. Then, we show how theories of working memory can be organized according to their…

Individual differences in the strategies that control sequential behavior were investigated in an experiment in which participants memorized sentences and then wrote them by hand, in a non-cursive style. Thirty-two participants each wrote eight sentences, which had hierarchical structures with five levels. The dataset included over 31,000 letters.…

Painful events establish opponent memories: cues that precede pain are remembered negatively, whereas cues that follow pain, thus coinciding with relief are recalled positively. How do individual reinforcement-signaling neurons contribute to this "timing-dependent valence-reversal?" We addressed this question using an optogenetic…

The spacing effect is among the most widely replicated empirical phenomena in the learning sciences, and its relevance to education and training is readily apparent. Yet successful applications of spacing effect research to education and training is rare. Computational modeling can provide the crucial link between a century of accumulated…

Sleep facilitates the consolidation (i.e., enhancement) of simple, explicit (i.e., conscious) motor sequence learning (MSL). MSL can be dissociated into egocentric (i.e., motor) or allocentric (i.e., spatial) frames of reference. The consolidation of the allocentric memory representation is sleep-dependent, whereas the egocentric consolidation…

This study explored under what conditions young children would set reminders to aid their memory for delayed intentions. A computerized task requiring participants to carry out delayed intentions under varying levels of cognitive load was presented to 63 children (aged between 6.9 and 13.0 years old). Children of all ages demonstrated…

Multiple lines of evidence suggest that glucocorticoid hormones enhance memory consolidation of fearful events. However, most of these studies involve male individuals. Since anxiety, fear, and fear-associated disorders present differently in male and female subjects we investigated in mice whether male and female mice perform differently in a…

Sleep is known to play an active role in consolidating new vocabulary in adults; however, the mechanisms by which sleep promotes vocabulary consolidation in childhood are less well understood. Furthermore, there has been no investigation into whether previously reported differences in sleep architecture might account for variability in vocabulary…

Recent studies have shown that exposure to a novel environment may stabilize the persistence of weak memories, a phenomenon often attributed to a process referred to as "behavioral tagging." While this phenomenon has been repeatedly demonstrated in adult animals, no studies to date have examined whether it occurs in infant animals, which…

Declarative memory performance is superior for items that were encoded in temporal proximity to reward delivery or expectancy. How reward-predicting contexts affect subsequent declarative memory formation in those contexts are, however, unknown. Using an ecological experimental setup in the form of a naturalistic driving simulator task, we…

In absolute identification, the extended generalized context model (EGCM; Kent & Lamberts, 2005, 2016) proposes that perceptual processing determines systematic response time (RT) variability; all other models of RT emphasize response selection processes. In the EGCM-RT the bow effect in RTs (longer responses for stimuli in the middle of the…

Don MacDougall's death was a rupture in our community of artist scholar educators. After all, how can we imagine our death? Heidegger (1953/2010) argues that death is 'eminent immanence' (pp. 241-251). For Derrida (1993), it is an aporia as it is something un/imaginable as a living being. Attached to Don's research at the time of his death brought…

The present study examined the activation of imaginal information on true and false memories. We asked whether forming mental images would lead to increases in true and false memories relative to a control group that did not form images. Participants in both groups studied 288 unrelated concrete objects, in which some of the objects were presented…

While much research shows that early sensory and attentional processing is affected by mind wandering, the effect of mind wandering on deep (i.e., semantic) processing is relatively unexplored. To investigate this relation, we recorded event-related potentials (ERPs) as participants studied English-Spanish word pairs, one at a time, while being…
