Open sourced Implicit Association Test (IAT) as a demonstration. This version will run locally in PsychoPy (mouse input) or online (including touchscreen input)

Fat-based implicit association test

A test of global versus local perception based on the Navon paradigm.

This code can be put at the start of an experiment to control angular image size. It estimates viewing distance from a blind-spot task and other info. See https://doi.org/10.1167/jov.21.8.19, and https://pavlovia.org/run/janbrascamp/blind_spot/html/

Sustained Attention to Response Time Task (SART)

This SART task is modeled on the framework used in The Irish Longitudinal Study on Ageing (TILDA)

Participants must press a button (mouse or onscreen) in response to a series of digits and withold responses on the number 3)

Each digit appears for 300ms, with an interval of 800ms between digits. The cycle of digits 1–9 is repeated 23 times, giving a total of 207 trials. The task lasts approximately for 4min
