The next 16 stimuli are randomly ordered presentation from the 8 images (4 upper class, 4 lower class) and words (4 positive, 4 negative).

* These are discounted in the analysis as per Nosek et al 2014. * 2 from condition 1 (Upper Class), 2 from condition 2 (Lower Class)

The first 4 images in the block are randomly chosen.

They have been replaced with free-to-use images from Pixabay (), and the images used have not been determined to be representative of the categories nor scientifically matched/determined.Īdapted for children to 4 blocks of 20 stimuli (12 Images, 8 words ). The original image stimuli for this task have been removed to prevent over-use of stimuli. NB: This task is only to be used as an example structure/setup for an B-IAT task, and should not be run as an experiment in its current form. Look for the ANT section (should be clearly marked)īrief Implicit Association Test (B-IAT) as conceived by Sriram & Greenwald (2009), with class-based stimuli adaptation by Adam McNamara. 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
