The face test items were presented for 1000 ms, and the shoes were presented for 500 ms. Different presentation times were used in order to equate difficulty across the two tasks, because pilot tests revealed that the shoe matching task was easier than the face matching task.
Assessing the subjective motion visibility after the discrimination task might somewhat underestimate the visibility at the time of discrimination, because of possible masking effects of the visual transient at the cessation of the stimulus, or simply because of the delay between the two tasks.
It shows that the character-based model performed better than word-based model in the two tasks, mainly because of the lower recall of the word-based model.
We consider that these differences between the two tasks were because inhibition of return is based on an old, earlier developing neural system.
However, the three tasks that solve the derivatives are grouped in order to simplify communication because the three tasks get the same input information from Y_smooth and send the results to velocities.
This is because regarding relationships between Criterion® holistic scores and TOEFL iBT® writing scores, one of the two tasks in the TOEFL iBT® writing was an integrated task whose features differed from Criterion® (and TOEFL iBT® independent) task.
This is because a voxel involved in two tasks could contain a population of neurons involved in both, as has been shown in the monkey [15], [16], [17] and/or two distinct populations, each of which being involved in only one of the two tasks, interdigitated within the volume of the voxel [21].
The number-matching task was always performed first because, in order to assess the difference between explicit and implicit tasks, it was critical to ensure that arithmetic remained task-irrelevant during the number-matching task and to minimize the transfer of task set between the two tasks.
We chose this simplification because we could not parsimoniously model the statistical dependence between the two task components.
However, in their experiment, no differentiation between absolute and relative strength of the three tasks was possible because all tasks were practiced to the same degree.
