![]() ![]() Findings from the individual testing in Stage 1 resulted in significant changes to documentation and training materials and identification of bugs to be corrected. In both individual and classroom testing, the students learned to effectively use PEAK within 2 h, and were able to create a lexical decision experiment in under 10 min. Formal usability testing was done in two stages: (1) detailed coding of 10 individual subjects in one-on-one experimenter/subject videotaped sessions and (2) classroom testing of 64 undergraduates. The application then executes experiments with centisecond precision. Students fill in a spreadsheet listing of independent variables and stimuli, insert columns that represent experimental objects such as slides (presenting text, pictures, and sounds) and feedback displays to create complete experiments, all within a single spreadsheet. The Psychology Experiment Authoring Kit (PEAK) is a novel spreadsheet-based interface allowing students and researchers with rudimentary spreadsheet skills to create cognitive and cognitive neuroscience experiments in minutes. More- over, all of its basic functions can be accessed by the non-programmer user through a graphic user interface (GUI) that requires no experience with computer programming.In academic courses in which one task for the students is to understand empirical methodology and the nature of scientific inquiry, the ability of students to create and implement their own experiments allows them to take intellectual ownership of, and greatly facilitates, the learning process. Of the various experiment-building sys- tems currently available, both on the Macintosh and the IBM-PC (Schneider, 1988), PsyScope is one of the most complete and powerful (Cohen et al., 1993). Many researchers have developed systems for laboratory timing and stim- ulus presentation using this computer (Chute, 1986 Bharucha et al., 1987 Westall et al., 1989 Rensink, 1990 Enns and Rensink, 1991 Busey, 1992 Doenias et al., 1992 Goolkasian, 1993 Haxby et al., 1993). DESCRIPTION PsyScope is a system for building behavioral experiments on the Apple Macintosh computer. A freeware version is available at the author's web site. The program supports a wide variety of experimental designs, multimedia formats, and stimulus control.
