In a previous paper (Roche, Stewart, & Barnes-Holmes, 1999), the graphic experiment generation software PsyScope (Cohen, MacWhinney, Flatt, & Provost, 1993) was reviewed and its relevance to behavioral research in the domain of language and cognition was outlined. Many behavioral researchers have since explored the potentials of this freeware application for the easy generation of behavioral experiments, particularly in the area of derived stimulus relations. In research contexts where the only behavior of importance is subjects’ response patterns on a keyboard, the experimenter needs only to arrange for the appropriate task presentations and the recording of responses. All of this is achieved easily using PsyScope, which is available for free download at http://psyscope.psy.cmu.edu/.
