Rogers and Monsell (1995) Conducted a Study Involving a Simplified

Rogers and Monsell (1995) conducted a study involving a simplified multitasking situation that aimed at measuring the cost of switching between two simple tasks. The difference in response time, as demonstrated in the trials, can be attributed to:

A) the time required to resume a task after interruption.
B) the task that required the participant to come up with appropriate responses and thereby increased performance significantly.
C) the need to switch attention between two different tasks.
D) the complex task that requires quick response to turn the attention of the participant.
