Perceived versus the actual ability for each of the four stepping tasks.

<p>A linear regression model was fitted to the data (dotted line). Because of the significant interaction effect with age group in the ‘cord’ task, we plotted the two different linear regression models for each age group. The identity line is indicated by the solid black line. Diamonds are representative for young adults, where circles are indicative for older adults. Participants that failed to successfully step over the string in the ‘cord’ task or step over the ‘river’ are indicated by an extra contour around the diamond or circle. The correlation coefficients are depicted in the top-left corner of each panel (*:p<0.05, **:p<0.01, ***:p<0.001).
