ListOutcomeTime frameDescriptionSource
PrimaryCognitive processes as assessed using Stroop testchange from baseline after 4 hour intervention on day1, day8, day16
Stroop test is a computer-based Stroop word and color test, including congruent trials and incongruent trials to assess inhibition. Reaction time and accuracy of the Stroop test will be collected before and after the intervention
ClinicalTrials.gov
PrimaryCognitive processes as assessed using D2 attention testchange from baseline after 4 hour intervention on day1, day8, day16D2 attention test is a paper and pencil test to assess attention. Concentration performance will be collected before and after the intervention.ClinicalTrials.gov
PrimaryCognitive processes as assessed using N back testchange from baseline after 4 hour intervention on day1, day8, day16
N back test is a computer-based test, including target images and non-target images. this test is for updating and working memory. The correct reaction number of N back test will be collected before and after the intervention.

Secondarymuscle activityrecording 5 minutes' muscle activity for each sitting posture, average RMS will be collected.it will be performed on another experiment day.Muscle activity is measured by the electromyograph (EMG)machine. RMS values will be collected and calculated as muscle activation during each sittings conditionClinicalTrials.gov
Secondarydiscomfort levelreport discomfort level immediately after each sitting condition(each sitting posture lasts 5 minutes).it will be performed on another experiment day.after each sitting condition, self discomfort level will be asked.0 means no discomfort,10 means the worst discomfortClinicalTrials.gov
