Y. Lacouture, EXPANDING MEL RESPONSE BOX TO ACCOMMODATE UP TO 16 EXTERNAL BUTTONS, Behavior research methods, instruments, & computers, 27(4), 1995, pp. 506-511
Micro Experimental Laboratory (MEL) is a widely used software package
developed for the automation of psychological experiments. This report
presents a simple way to implement and use an expanded MEL response b
ox that accommodates up to 16 external switches. Hardware and software
considerations are reviewed, and relevant MEL code is provided. This
includes a simple algorithm that permits the reading of multiple respo
nses within a single trial.
