PsychoPy is an open-source application, written in Python, to allow the presentation of stimuli and collection of data for a wide range of neuroscience, psychology and psychophysics experiments. For this experiments we are using the 1.79.00 version.
PsychoPy is used by the University Medical Center Freiburg to design the DECT itself and store the results for subsequent statistical analysis. The protocol is that PsychoPy sends Frapper all the parameters require to generate the facial animations, and in turn Frapper sends back timing information and acknowledgement that a trial has been finished.
