A text-stimuli presentation manager for the IBM PC with ipsatization correction for response sets and reaction times

IPSAPRO, an ipsative scoring program written for the IBM PC, aids in the detection and transformation of response sets that often contaminate rating scale and reaction time experiments. Response sets such as the tendency to use only extreme points of a rating scale or to work for speed over accuracy in reaction time experiments are removed in IPSAPRO by standardizing each subject’s ratings or times against their own means and standard deviations. Ipsatization can be applied to existing data sets or take place automatically at the data collection stage in a text-stimuli presentation manager that is provided with the program.
