Prioritized encoding and retrieval of valuable information is an essential component of human memory due to capacity limits. Individual differences in value-directed encoding may derive from variability in stimulus valuation, memory encoding, or from strategic abilities related to maintenance in working memory. We collected multiple cognitive ability measures to test whether variation in episodic memory, working memory capacity, or both predict differences in value-directed remembering among a large sample of participants (n=205). Confirmatory factor analysis and structural equation modeling was used to assess the contributions of episodic and working memory to value sensitivity in value-directed remembering tasks. Episodic memory ability, but not working memory capacity, was predictive of value-directed remembering. These results suggest that cognitive processes may be differentially related to value-based memory encoding.

Individual differences in repetition priming is an often-overlooked area of research. The importance of this neglect becomes evident when considering the criticisms that priming research has received in the last decade concerning reliability. The current researched aimed to investigate whether individual differences in working memory capacity and affective states have differential effects on lexical-semantic repetition priming outcomes based on whether participants were first or second English speakers. Using logistic mixed-effects models to account for subject variation, the current paper investigated a three-way interaction between working memory capacity, negative affect score, and language on repetition priming outcomes. The results indicate that a statistically significant three-way interaction exists. We present an argument which posits that an individual’s primary language and subsequent familiarity with the primed concepts, in conjunction with individual differences in working memory capacity and mood, plays an important role in determining the most effective strategy used to complete a word-stem completion task.

AbstractPrevious studies have associated visual working memory (VWM) capacity with the use of internal attention. Retrocues, which direct internal attention to a particular object or feature dimension, can improve VWM performance (i.e., retrocue benefit, RCB). However, so far, no study has investigated the relationship between VWM capacity and the magnitudes of RCBs obtained from object-based and dimension-based retrocues. The present study explored individual differences in the magnitudes of object- and dimension-based RCBs and their relationships with VWM capacity. Participants completed a VWM capacity measurement, an object-based cue task, and a dimension-based cue task. We confirmed that both object- and dimension-based retrocues could improve VWM performance. We also found a significant positive correlation between the magnitudes of object- and dimension-based RCB indexes, suggesting a partly overlapping mechanism between the use of object- and dimension-based retrocues. However, our results provided no evidence for a correlation between VWM capacity and the magnitudes of the object- or dimension-based RCBs. Although inadequate attention control is usually assumed to be associated with VWM capacity, the results suggest that the internal attention mechanism for using retrocues in VWM retention is independent of VWM capacity.
