![]() A fibre-optic, light-sensitive key press interfaced with the PsyScope Button Box (New Micros, Dallas, Texas) was used to record participants’ behavioral. Participants viewed the screen through a mirror. The students were typically able to create their own projects in 2 h. Stimuli were projected to participants with an Epson (model ELP-7000) LCD projector onto a screen positioned at the head end of the bore. Many PsyScope users already possess and use a Button Box as a response interface for subjects, but may be unaware of its potential as an interfacing device. Such testing will improve the approach with each semester. The Button Box houses three large colored response keys that can be used as response keys for any PsyScope script. Stage 2 testing identified additional bugs to be corrected and new features to be considered to facilitate student understanding of the experiment model. 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 participant was instructed to use the index finger of their preferred hand and to keep their finger poised above the middle (i.e., yellow) button at the start of each trial. ![]() ![]() The coloured buttons on the PsyScope button box are ordered, left to right, red, yellow and green. The application then executes experiments with centisecond precision. The duration of the button press was not recorded. 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. 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.
