We found that those who performed the highly controllable Wheel Stopping task had less of an increase in stress in response to the stressor, and a greater decrease in stress after being debriefed that they didn’t have to complete the stressor task after all. 7/n
Two graphs showing the change in subjective stress between the two respective timepoints: a) Stress Induction – from before to after the stressor, and b) Stress Relief – from after the stressor to after the stressor debrief. There is higher stress induction and less stress relief for the Neutral Control Condition (videos) compared to the Highly Controllable Condition (Wheel Stopping task)

Feeling more in control was tightly coupled with feeling less stressed during the task, even after accounting for perceived task difficulty. Higher mean subjective control and lower subjective stress were also associated with lower initial state and trait anxiety and depressive symptom severity. 5/n
Scatterplot showing the negative association between subjective control and subjective stress during the Wheel Stopping task for both studies. The regression line shows the relationship between subjective control and subjective stress, after accounting for perceived task difficulty and random effects of participant and timepoint.

We developed a Wheel Stopping task to measure and manipulate subjective feelings of control by changing the wheel’s speed, segment size, and deceleration. A linear model showed that trial-by-trial variation in task parameters captured fluctuations in subjective control at the individual level. 4/n
Figure with 3 panels: a) Histogram of parameter estimates across all participants showing that there is variation across participants. b) Histogram and box plot of individuals' correlation coefficients between their model predicted and actual control ratings for both studies (the median r for Study 1 = 0.54 and Study 2 = 0.69). c) A plot of control ratings over the time course of the experiment, with control ratings predicted from the model in red, and the actual ratings in blue, shown for 3 randomly selected participants per study. This shows that the model predicted values tightly couple the actual responses.
