A Researcher Records Mean Response Time in Milliseconds for a Group

question 4

Multiple Choice

A researcher records mean response time in milliseconds for a group of participants who perform a Donders A task and a Donders C task under two conditions. In one condition, they do the reaction time tasks alone; in the other condition, they perform the two tasks while doing a secondary attentionally demanding task at the same time. Reaction times for the Donders A task are the same for both conditions of the experiment; however, reaction times for the Donders C task are longer when the secondary task is being performed. Using the subtractive method, these results suggest

• A) the secondary task slowed down the baseline reaction of the participants.
• B) the secondary task speeded up the baseline reaction of the participants.
• C) the secondary task slowed down the identification time of the participants.
• D) the secondary task slowed down the selection time of the participants.
