![]() ![]() There is an example R Analysis script in this GitHub repository, which (amongst other questionnaires/tasks) codes for the analysis of this task. On the resolution range I tested, the only resolutions with possible issues are: 1280x768 1360x768 or 1366x768, where the central arrow appears out of line with the rest. NB: These stimuli size, gap, and total size will be different on different resolution screens.For now, the stimuli are scaled on a 1920 x 1080 screen to be (approximately): 6mm, with 2mm gap, and 3.9cm in total (all 5 flanker stimuli).The Screen Calibration Zone, which is not yet available, may help with this in future. Controlling for device used, different screen size & resolution, and viewing distance is difficult logistically with remote testing in Gorilla.This was at 65cm viewing distance so would be 6.240mm stimuli, 0.0681mm gap and 3.950cm in total ![]() The stimuli (one central arrow plus four flankers) consisted of a total 3.08 degrees of visual angle". "A single arrow or line consisted of 0.55 degrees of visual angle and the contours of adjacent arrows or lines were separated by 0.06 degrees of visual angle.The images are not sized accurately according to Fan et al.:.The last fixation cross (fixation 3) needs to be 3500 - ( + ).The initial fixation cross (fixation 1) has a random duration of 400-1600ms.The background colour is grey, with the text black.We split this to smaller blocks to aid in online delivery/focus mTBI/Concussion Screening Form: Post-Season ScreenĢ Blocks of 12 practise trials, one without cueing, one with cueing (making the 24 trial full feedback practise block of Fan et al).Ĥ Blocks of 48 task trials (12 without cueing, 12 with dual asterisk cue, 12 with central asterisk cue, 12 with one asterisk ) NB: Fan et al had 3 blocks of 96 trials.mTBI/Concussion Screening Form: Supplementation and Diet Screening.mTBI/Concussion Screening Form: Sports-related information.mTBI/Concussion Screening Form: Head Injury.mTBI/Concussion Screening Form: Demographics.Example Experiment: Concussion Screening & Questionnaires/Task.Please email for me to send, and to get permissions from authors.
