Non-adaptive strategy selection in adults with high mathematical anxiety

Participants with mathematical anxiety (MA) tend to show particular difficulty in mathematical operations with high working memory (WM) demands compared to operations with lower WM demands. Accordingly, we examined strategy selection to test the cognitive mechanism underlying the observed weakness of high MA participants in mathematical operations with high WM demands. We compared two groups of college students with high or low MA, in the solution of simple non-carry addition problems (e.g., 54 + 63) and complex carryover addition problems (e.g., 59 + 63). The results indicated that high MA participants showed particular difficulty in the harder carry condition. Testing the strategy selection mechanism among high MA participants, we found in the carry condition 1) they used the common strategy less often compared to low MA participants and 2) employed unusual strategies more often compared to low MA participants. Therefore, high MA participants were less efficient in their strategy selection, which may be due to weaker spatial representations, numerical difficulties, or less experience solving complex problems. These primitive representations are not adaptive, and can negatively impact performance in math tasks with high WM demands

Previous studies demonstrated that individual differences can modulate the perceived size of an object. Two factors that affect perceived size are stimulus valence and its self-relevance to the observer. Whereas most of the previous literature focused on perceptual size, the current study examined whether these factors also modulate conceptual size. Spider pictures carry negative valence, but they are also self-relevant to those who are afraid of them. Thus, the current work used pictures of spiders and asked whether we all possess an exaggerated conceptual size of spiders (because of the negative valence they possess), or whether this size bias occurs only in people who are afraid of spiders (because spiders are self-relevant stimuli for them). Participants extremely high or low in fear of spider rated the conceptual size and the unpleasantness of pictures of spiders and other animals. Results indicated that although both groups rated spiders as more unpleasant than the other animals, only the highly fearful participants showed conceptual size bias for these stimuli. These findings suggest that bias in conceptual size is specific to the fear-inducing stimulus and is not directly influenced by the stimulus unpleasantness.
