RTLAB: A Reaction-Time Laboratory for the Data General NOVA Minicomputer

Pagination or Media Count:
RTLAB is a package of relocatable assembly-language subroutines for the design, control, and analysis of behavioral experiments on the Data General Corporation NOVA family of computers. It was originally designed for use in reaction time research but is readily adaptable to any discrete-trial task. RTLAB accepts design parameters from the experimenter for a given experiment and then produces an appropriately randomized and counterbalanced set of trials for presentation to a subject. During an experimental session RTLAB controls the presentation of stimuli, the acceptance and scoring of responses, and all of the timing and input-output constraints associated with control and data acquisition. Its current design does not allow for time-sharing among more than one subject station. A history of the experiment is saved for later analysis and transfer to storage media. User modifications of any of the details of these operations are facilitated by the organization of RTLAB into subroutine modules. The organization of RTLAB and its use are presented along with sufficient documentation of the routines to allow user modification where appropriate.
