MATLAB experiment tools

Functions that may be useful for running psychological experiments in MATLAB using Psychtoolbox.

List of functions

• getChoice.m records which of two keys was pressed, and determines whether this was the appropriate response. Useful in the context of two-alternative forced choices.
• likertScale.m draws a Likert scale and statement to the screen, and returns the selected level of (dis)agreement, reaction time, and a logical element indicating whether or not a response was made.
• screenSetup.m creates an on-screen window for presenting stimuli, and if necessary prepares image files to be drawn to the screen.
• quitExperiment.m in case a specified key (e.g. escape) has been pressed, draws text to the screen, and returns a logical index in case this key is pressed once more.

Dependencies

These functions were written in MATLAB R2014a on a Windows 7 PC using Psychtoolbox version 3.0.13. I haven't checked the compatibility with other operating systems and/or software versions.
