A customizable and extendable change detection experiment written in Psychopy. Designed for the desktop.

In this experiment participants are required to respond whenever the stimulus (square) location matches its location the previous trial (N-back-1). N-back-2 trials involve responding whenever the location of the square is the same as its location 2 trials before. This task is based on Kirchner (1958) experiment.

testing to see how real-time mouse position collection could work

Created for Eliza Yujun Ng December 2018

Numbers are presented at a rate of one per second. The first digit cannot be 0 Following digits can be 0 but cannot be the same as the previous digit.

If the answer is correct the span is increased for the next trial If the answer is wrong the span is decreased for the next trial

If there are at least two errors at a given span and that represents more than half of the total attempts at that span then the experiment ends, returning a span of one less than the final span attempted.

An embedded html demographics form (online only) using iFrame code shared by @arnon_weinberg. The responses are saved to the data file as expInfo variables, which means that they will appear on every line of the data if the form is placed first.

Demo of a visual search task for use online. User can manipulate setsize, target colour, letter orientation. Accuracy and response time recorded.

A forward and Backward Digit Span test for Working Memory The test adapts to participnts' answers and a score is calculated following Woods et al. (2012)

A demo based on the Posner Cueing Effect.

An example of a visual search task. Participants must search for the letter T amongst distractor letters.

A T and L visual search experiment in psychopy

The Attention Network Task (Fan et al., 2002).

This experiment runs a working memory task similar to the distractor-based change detection task of Vogel Machizawa (2005) (see also Lenaert et al., 2016). Colored targets are shown in left & right visual field, attention is directed using a cue. Distractors can be presented in addition to targets.
