Running the Button Box for the First Time The easiest way to do this is to modify an existing experiment. Whichever program you use to run your experiment, you need a script that tells the program how to present your stimuli and what kind of information to record about the responses. Other professional experiment presentation programs include Presentation, E-prime, PsyScope, and DMDX. This level of accuracy is particularly important in experiments designed to measure some cognitive function or sub-conscious reaction. It is capable of recording more accurate reaction times than Praat. A good reason to use PsychoPy instead of Praat is if you want to measure reaction times. The Phonology Laboratory has the freely available PsychoPy on the three pcs located outside the sound booths. You have a variety of options when choosing how to design your perception experiment we suggest using PsychoPy or Praat. Perception and artificial grammar learning experiments both typically involve presenting stimuli to experiment subjects and eliciting a response, often in the form of a choice between a small set of alternatives (such as “same”/”different”, or “grammatical”/”ungrammatical”, or a rating on a 7-point scale). Two kinds of experiments that may be run with this equipment are perception experiments (eliciting responses to naturally produced or synthesized audio stimuli), and artificial grammar learning experiments, which involve an exposure phase followed by a test phase that is similar to a conventional perception experiment.
