Short mindset intervention effective in attitude change but no evidence of transfer to improved cognitive outcomes of working memory capacity and standardized test performance

Abstract

There has been extensive research conducted on mindset, involving both experimental and observational methods. However, the findings in the literature remain mixed. This should give educators and researchers pause from an intervention perspective —if we still do not have a good understanding of how mindset works, then more research is needed. To better understand how mindset interventions work, we looked at self-report measures as well as post-intervention behavior within and across individuals. We implemented a mindset intervention to improve cognitive performance measures relevant to academic performance—working memory capacity and standardized test performance in math. We also explored individual differences in academic attitudes (e.g., academic identification and sense of belonging in university) that might moderate students’ mindset and the effect of the mindset intervention on subsequent cognitive performance. We expected the malleable mindset intervention to significantly improve cognitive performance and to cause more positive academic attitudes and attitudinal change. The mindset intervention did change students’ beliefs about ability but also caused students to report higher grit (no condition difference), and to feel less belonging in terms of connection to their university—which was not in line with our hypotheses. We also found that the malleable mindset intervention had no significant effects on improving WMC or standardized test performance. We discuss the implications of these findings and make suggestions for future work in this area.
