Simple calls to increase effort influence attention, mind wandering, and learning during online lectures

Year: 2026

Abstract: Mind wandering is a prevalent contributor to poor retention of lecture content. This study examined whether simply directing students to “try harder” can enhance attention and learning in recorded lectures. In two experiments ( N = 113 and N = 100), participants watched a 45 min recorded lecture while periodically responding to probes measuring attention (Experiment 1) or intentional and unintentional mind wandering (Experiment 2). Two-thirds through the lecture, half of participants received a prompt directing them to “try harder” to learn from the remaining portion of the lecture (experimental, try harder condition), while the other half received a neutral prompt (control condition). The try harder prompt significantly increased self-reported attention (Experiment 1) as well as decreased intentional and unintentional mind wandering (Experiment 2). In Experiment 2 (but not in Experiment 1), the try harder prompt also led to a nominal improvement in retention of post-prompt lecture content, a change that was statistically different from the corresponding change for controls, which was nominally in the opposite direction. These effects occurred without explicit incentives or between-group differences in motivation, suggesting that directly targeting effort mobilization may be sufficient to enhance learning outcomes. These findings endorse directing students to try harder as a practical technique for improving attention and retention in recorded lectures.
