Table 3.

Three hypotheses to address the research questions.

Hypothesis RQ Inline graphic = null hypothesis Inline graphic = alternate hypothesis
1 RQ1 TRP de/synchronization patterns measured in different frequency bands do not change under different eye conditions used as the baseline TRP de/synchronization patterns measured in different frequency bands change under different eye conditions used as the baseline
2 RQ2-(a) Using the eyes-open baseline condition, TRP values by bandwidth at the left-side and right-side channels within the same sketching task are the same Using the eyes-open baseline condition, TRP values by bandwidth at the left-side and right-side channels within the same sketching task are different
3 RQ2-(b) Using the eyes-open baseline condition, TRP values by bandwidth at each channel in TTCT-IF sketching and DwMT sketching are the same Using the eyes-open baseline condition, TRP values by bandwidth at each channel in TTCT-IF sketching and DwMT sketching are different
