A computerized modification of Sternberg memory test with additional perceptual distraction

We describe a package of programs in Turbo Pascal which enables us to present six different versions of the modified Sternberg memory test and to evaluate the subject's performance. The program starts presenting a brief series of randomly generated visual stimuli (digits/colors) which are to be memorized, followed by the target stimulus. The series could either include the target or not. Noise in the form of colors or digits could be added to the stimuli. The reaction times of 'yes' or 'no' responses are evaluated separately and presented in numerical and graphic forms.
