The students were typically able to create their own projects in 2 h.
Subjects viewed single uppercase letters, presented centrally in Helvetica 24 pt font, white on a black background. Such testing will improve the approach with each semester. Subjects responded by pushing a fiber optic light-sensitive key- press connected to a Psyscope Button Box (Carnegie Mellon University, Pittsburgh, PA, USA) that recorded both accuracy and reaction time. 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 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.
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. called the PsyScope button box which provides timing accurate to one. 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. Stimuli were projected to participants with an Epson (model ELP-7000) LCD projector onto a screen positioned at the head end of the bore. Abstract-PsyScope is a system for building behavioral experiments on the Apple. 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.
