====== Clock Task ======

MATLAB/[[:tools:pyschtoolbox]] task code is available on [[https://github.com/LabNeuroCogDevel/CogEmoFaceReward|github:CogEmoFaceReward]]. It was developed for [[:grants:multimodal|MultiModal]]/[[:grants:mmy4|MultiModal Year 4]] (2015). Additional usage and development continued by [[https://www.dnpl.pitt.edu/|DNPL]] and [[https://dependlab.unc.edu/|dependlab]] (Dombrowski, Hallquist), including a port to [[:tools:inquisit]] and [[https://pmc.ncbi.nlm.nih.gov/articles/PMC10889364/|2025 publication]].

For [[:tools:MEG]] timing, a corner box flashes black/white to encode event display onsets with a [[:tools:photodiode]].
