However, the SNR for female faces did not differ across task-irrelevant and task-relevant conditions (two-tailed t-test, V1: t(27) = −1.0, P = 0.317, FG: t(27) = −0.9, P = 0.387).
It is evident that the reported values differed across tasks, although the percentage of variance accounted for by the linear fit (R2) was high for both tasks.
When timing variability has previously been compared in explicit and implicit measures of motor timing, temporal variance differed across tasks, suggesting that separable timing mechanisms were recruited [7], [8], [26], [36].
The consequences of sedentary behavior may differ across groups.
We note that the presence and direction of interactions between factors predicting SPEs differed across task choices and ratings (and also across experiments, see below), which may be due to the boundedness of the rating scale creating ceiling/floor effects that do not affect task choices.
In addition to the type of neural activity, the data provide no evidence that the time at which switch-related activity occurred differed across task and source switches.
While the repeated nature of discrete choice experiments is advantageous from a sampling efficiency perspective, patterns of choice may differ across the tasks, due, in part, to learning and fatigue.
However, this preparatory activity did not differ across the 2 tasks, despite large task asymmetries in behavioral switch costs and subtle but consistent biases in task choices.
Our analyses focused primarily on preparatory activity related to intentional and motor-specific task preparation observed before the presentation of the imperative stimulus and ensuing task performance on each trial; of interest was whether this preparatory activity would differ across the 2 tasks.
Subjects' choices did not differ across these versions of the task (completed by 26 and 39 subjects, respectively), and therefore we combine the data from the two versions.
