Abstract
The use of thought-probe methodologies during tasks with varying loads has become commonplace. The current study aimed to investigate whether there exists an interaction between probe frequency and task load on responses of mind wandering episodes, using within-subject designs. In Experiment 1, We performed 0-back, 1-back, and 3-back tasks, in which low-frequency and high-frequency thought probes were presented to the participants. The results indicated that fewer probes led to more reported mind wandering episodes during 0-back and 1-back tasks. Conversely, a significant increase in mind wandering was observed in the 3-back task when higher-frequency probes were used. Experiment 2 introduced the probe relatedness dimension to the medium- and high-load tasks. Both experiments demonstrated that increasing probe frequency reduced mind wandering during the low- and medium-load tasks, but increased it during the high-load task. Additionally, Experiment 2 revealed that higher probe frequency resulted in more probe-related mind wandering during the high-load task, but not during the medium-load task. The current findings reveal the interaction effect of probe frequency and task load on mind wandering and offer possible explanations.
