Conceptual overlap among texts impedes comprehension monitoring.

For decades, research on metacomprehension has demonstrated that many learners struggle to accurately discriminate their comprehension of texts. However, while reviews of experimental studies on relative metacomprehension accuracy have found average intra-individual correlations between predictions and performance of around .27 for adult readers, in some contexts even lower near-zero accuracy levels have been reported. One possible explanation for those strikingly low levels of accuracy is the high conceptual overlap between topics of the texts. To test this hypothesis, in the present work participants were randomly assigned to read one of two text sets that differed in their degree of conceptual overlap. Participants judged their understanding and completed an inference test for each topic. Across two studies, mean relative accuracy was found to match typical baseline levels for the low-overlap text sets and was significantly lower for the high-overlap text sets. Results suggest text similarity is an important factor impacting comprehension monitoring accuracy that may have contributed to the variable and sometimes inconsistent results reported in the metacomprehension literature.

Mental counters as an online tool for assessing working memory capacity.

Working memory capacity (WMC) describes an individual's ability to focus their attention in the face of interference which allows them to actively maintain and manipulate information in immediate memory. Individual differences in WMC predict a wide range of psychological constructs. The development of online measures can enable data collection from broader, more diverse samples than those typically collected in person in laboratory settings. In addition, logistical challenges brought on by the COVID-19 pandemic have mandated the need for reliable and valid remote assessments of individual differences that are both culture-fair and less susceptible to cheating. This study reports details of a new online version of a Mental Counters task that takes only 10 min to collect and provides evidence for its reliability and convergent validity with other measures including Picture Span and Paper Folding.

Metacognitive accuracy across cognitive and physical task domains.

Metacognition is often considered a critical component of learning and higher-order cognition; however, does metacognitive accuracy remain constant across all tasks, specifically in tasks that involve physical or procedural components? To investigate the consistency of metacognitive judgments across various task types, participants completed word and number recall tasks, and also completed three simple physical skill tasks (e.g., catching a ball in a cup). Participants made metacognitive judgments about their performance in all tasks. Results indicated that while participants demonstrated traditional levels of relative metacognitive accuracy in more cognitive tasks, participants were significantly more accurate in their judgments for physical skill tasks. In other words, relative accuracy for metacognitive judgments in physical tasks appears to be significantly higher than for cognitive tasks. This represents the first such demonstration of this effect and suggests that characteristics of physical tasks somehow improve participants' judgments of how well they have learned.
