Figure 1. Flanker attention task and behavioral metrics. (A) A fixation cross was presented for 1,500 (± 50) ms followed by a row of 5 arrows for 2,500 ms. Participants were instructed to indicate whether the middle arrow was pointing to the left (right index finger) or right (right middle finger) via button press. (B) Residuals of reaction time and accuracy accounting for the effect of age for each condition are given on the y-axis and group on the x-axis. Cognitively impaired participants (ADS/HAND groups) were less accurate and slower to respond than cognitively normal adults. However, those on the ADS generally performed similar to participants with HAND. *p<.05.
