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

The Visual Preference for Facial Expressions task uses eye tracking to measure how long people look at different emotional expressions (like happy or sad faces) to understand attentional biases.

In this task participants are required to press either left or right arrow key depending on which way the fish in centre is facing. Participants are required to ignore the direction of the surrounding fish. This is a children version of Flanker Task based on M. Rosario Rueda et al. (2004).

In this task participants are required to memorise and recall number series in order. Participants start out with three 3-digit sequences. If participants correctly recall 2 out of 3 three sequences, they progress to 4-digit sequence trials and so on. If participants respond incorrectly on 2/3 trials the experiment terminantes. This experiment is based on the original digit span experiment by Jacobs (1887).

In this task participants are required to sort the presented cards based on a rule. The rule is unknown to the participants, however they receive feedback whether their answer was correct. The rule changes after certain amount of trials. This experiment is based on Grant & Berg (1948) 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.

A minimalist antisaccade task measuring attention and response control, can be adapted for eye tracking.

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

Sternberg Working Memory Task demo.

A demo based on the Bilingual Stroop effect. Also demonstrates how to achieve a counterbalanced design.

A demo based on the Posner Cueing Effect.

The purpose is the test which kind of emotion affects memory Using images with relative music for test memory
