Below are some examples of psychological tasks I have developed. All tasks are free to use under their respective licenses. If you would like to know more, please reach out to me at michael.colwell@psych.ox.ac.uk.
A free psychological task measuring behavioural inhibition during interference with affective distractors. Initially developed for use in this study, and is currently in use across multiple active research studies, including studies on remitted depression and GLP-1 agonists in the Department of Psychiatry, University of Oxford. Available for free on the github repository.

The task materials and preprocessing script are offered free of charge for researchers. It is requested that researchers who publish work using these materials (task or preprocessing script) cite the below paper(s).

A task measuring complex verbal working memory (verbal n-back) designed for non-scanner and scanner (fMRI) use. Designed and rolled out across multiple research studies, including multiple psychopharmacology studies and a neuroimaging study (NCT05849675).
Available for free on the github repository. Data processing and analysis scripts, including an automatic temporal-task synchronisation scripts, are included in the here.

A task measuring visuo-spatial working memory designed for mouse/track-pad only use. The task includes memory for spatial and feature (colour) information. Colours in the task use a palette known as 'Color Universal Design (CUD)' created by Masataka Okabe and Kei Ito to allow colour discriminations across all colour-blind populations.
Available for free on the github repository, including data preprocessing scripts. The task materials and preprocessing script are offered free of charge for researchers. It is requested that researchers who publish work using these materials (task or preprocessing script) cite the below paper(s).

For published academic papers, I strive to provide reproducibile data processing pipelines in line with open science principles. These pipelines show how the raw, de-identified data during study experimentation were cleaned, preprocessed, computationally modelled (if appropriate) and statistically analysed. Please visit my github for a recent example.
