Methodological Artifact

Updating is the executive function (EF) previously found to most strongly relate to higher cognitive abilities such as reasoning. However, this relationship could be a methodological artifact: Measures of other EFs (i.e., inhibition and shifting) usually isolate the contribution of EF, whereas updating is measured by overall accuracy in working memory (WM) tasks involving updating. This updating accuracy-score conflates updating-specific individual differences (e.g., removal of outdated information) with variance in WM maintenance. Re-analyzing data (N = 111) from von Bastian et al. (2016), we separated updating-specific variance from WM maintenance variance. Updating contributed only 15% to individual differences in performance in the updating tasks, and it correlated neither with reasoning nor with independent WM measures reflecting storage and processing or relational integration. In contrast, the WM maintenance component of the updating task correlated with both abilities. These findings challenge the view that updating contributes to variance in higher cognitive abilities.

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.
