Abstract: | _Objective:_ We examined whether individual differences in positive and negative affective states predicted dual-task costs using an established Dual-Task Walking protocol in non-demented older adults. We hypothesized that positive and negative affect would be associated with smaller and larger dual-task costs, respectively._ Methods:_ Participants (N = 403; mean age = 76.22 ± 6.55; females = 56%) completed the Positive and Negative Affect Schedule and the walking protocol involving three conditions: Single-Task-Alpha, Single-Task-Walk (STW), and Dual-Task-Walk (DTW). Gait velocity was assessed via an instrumented walkway. _Results:_ Negative affect was associated with greater decline in gait velocity from STW to DTW (95% confidence interval [-0.73 to -0.03]) but not the decline of the rate of correct letter generation. There was no significant relationship between positive affect and DTW performance._ Discussion:_ Findings suggest negative affect is adversely associated with allocation of attentional resources, leading to worse mobility outcomes in older adults. |
