A typing specialist would like to evaluate the effect of task-switching (asking someone to switch between various tasks) and room lighting on reaction time (milliseconds) in a group of 5 students in his class. He asks these 5 students to complete a computer task in which they are to judge whether or not a number is odd or even by pressing a certain key on the keyboard. He rst has them complete this tasks in a room with very dim lighting. and then. an hour later, brings them back to complete the same task in a brightly-lit room. He sends them home, and asks them all to return on the following day, at which point they complete a task which alternates between asking them to identify an even/odd number and identifying whether or not the number is less than or greater than 5 (thus, there are two different tasks incorporated into the program). He has them do this in a dimly-lit room, and again, after an hour, calls them back to do it again in a brightly-lit room. Use an alpha level of .05 to assess the effect of task-switching and lighting on reaction time. No Task- Task- Switching Switching Dim lighting Bright lighting
