Abstract
Previous research has found that gestures influence adopted strategies during problem solving of the gear-system task. When gestures are used, a perceptual-motor strategy is usually adopted, whereas when gestures are restricted, a more abstract strategy is used. Next to that, strategy switches may indicate differences in variability from a functional dynamic perspective. The present study aims to replicate previous studies about these topics and analyze them further. Two hypotheses were evaluated about 1) the effect of gesture use (restricted or allowed) on discovering an abstract strategy during the gear-system task and 2) how greater variability will be shown in the earlier trials of the experiment, when gesture use is restricted. Furthermore, variability and strategy switches will be visualized to exploratively investigate the potential influx of variability that may occur before strategy switching. Participants (N = 120) were randomly assigned to two conditions, gesture-restricted and gesture-allowed, and asked to solve the gear-system task. Video recordings were made and through coding and multimodal processing, including recurrence quantification analysis, a large dataset was produced to investigate the hypotheses. Our study did not find an effect of condition (gesture-restricted or gesture-allowed) on using a more abstract strategy. Next to that variability was not larger in the first trials for the gesture-restricted condition. The visual comparison, however, gave a promising insight into variability and strategy switching. Future research should focus on further replicating gesture studies and investigating variability with strategy changes to gain more insight in human cognition.
