Stan and Oliver,famous psychologists,are interested in determining how fast people can respond to a signal flashed on a computer screen.At the start of each trial,the computer displays a Get Ready sign,then the screen goes blank.After a short delay,the signal is flashed on the computer screen and the subject presses a key as quickly as possible.In condition one,the duration of the short delay is always the same length of time.In condition two,the short delay changes randomly from trial to trial.According to research in high-speed decision making,the subjects in condition one are ____ than those in condition two because of ____.
A) slower; complexity
B) slower; stimulus-response compatibility
C) faster; expectancy
D) faster; speed-accuracy tradeoff

Question

Quizplus · Accepted Answer

The subjects in condition two have to process and prepare for different delay times, which leads to decreased expectancy and slower response times. In contrast, the subjects in condition one can expect the same delay time and therefore react faster. The answer is not A or B because complexity or stimulus-response compatibility are not mentioned as factors affecting response time. The answer is not D because there is no mention of a tradeoff between speed and accuracy in this study.
