Stress and Psychosocial Distress Scale with Blunted Oscillatory Dynamics Serving Abstract Reasoning

Figure 2

Abstract reasoning task paradigm. Participants were presented with an empty grid of gray boxes for 2500 to 3000 ms with either the left or right bottom square highlighted by a white border to indicate the location of the upcoming target. Complex images then populated each of the four squares within the grid for 4000 ms. Participants indicated whether the image in the highlighted square correctly completed the pattern in the grid by responding via button press (i.e., right index finger for matching patterns, 60 trials; right middle finger for nonmatching patterns, 60 trials). Match and nonmatch trials were presented in a pseudorandomized order for the duration of the task. Participants performed well on the task, with a mean accuracy of 84.70% () and a mean reaction time of 1991.10 ms ( ms).
