Instructions for the Subject There are three tasks with varying difficulty. Four questions will be given total for each task. You will answer these four questions in two sessions. You will be assigned to a task schedule by the Administrator. An example schedule looks like this: E2 -> I1 L M (ML) H (HM) (MH) According to this schedule you will use Elastic Windows interface to answer Question Set 2, and then use Independent Windows interface to answer Question Set 1. Each question set involves three tasks of low, medium, and high complexity indicated by letters L, M, and H respectively. According to the above schedule you will be asked first to open documents for task L, and then answer two questions. When assigned to a task, you are required to read both of the questions loudly even before opening the documents for that task. You should tell the administrator what you are going to do as well.You will be timed separately for opening these documents and answering each of the two questions. When ready tell the administrator to start timing and when done tell him to stop. You are welcome to ask any questions before starting to work on a task. Since there are two more questions regarding task L later, you will be asked to either minimize or iconize these windows depending on the interface. Secondly, you will do task M similarly. After finishing task M do not minimize or iconize windows related to that task immediately since at this point the administrator is going to measure the time you need to switch to task L. The experiment goes in a similar fashion.
