This experiment gives students the opportunity to determine whether their reaction times are reliably different for conditions that require slightly different decisions.
Objectives
• To examine the hypothesis that as the amount of information to be processed increases the time required to choose between alternatives also increases
• To examine differences among participants and their rate of information processing Equipment

Preparation
Conditions/Tasks
- Simple reaction time
- Physical matching
- Name matching
- Class matching
Procedure
Each participant will complete four blocks, of ten trials, for each condition (task). First block of trails is a practice run.
Analysis
Analyze the class data and answer the following questions: - Plot reaction time against reaction task
- Which task took the greatest amount of time for the class? Which task took the shortest amount of time for the class?
- Which task had the greatest amount of errors for the class? Which task had the least amount of errors for the class?
CIM 612/412: HCI LABORATORY 2 Spring 2021 Reaction Time Prof. Millet - How does the time required to perform Task 1 compare with the time required to perform each of the following tasks with matched vs. unmatched trails (for Tasks 2-Task 4)? Support your answer with a sound rationale:
- Task 1 vs. Task 2?
- Task 1 vs. Task 3?
- Task 1 vs. Task 4?
- Task 2 vs. Task 3?
- Task 2 vs. Task 4?
- Task 3 vs. Task 4?
- How does the error rate for Task 1 compare with the error rates of each of the following tasks with matched vs. unmatched trails (for Tasks 2-Task 4)? Support your answer with a sound rationale:
- Task 1 vs. Task 2?
- Task 1 vs. Task 3?
- Task 1 vs. Task 4?
- Task 2 vs. Task 3?
- Task 2 vs. Task 4?
- Task 3 vs. Task 4?
- How does the time required to perform tasks with matched trials compare with the time required to perform tasks with no-match trials? Support your answer with a sound rationale:
- Physical Matching match trails vs. no-match trials
- Name Matching match trails vs. no-match trials
- Class Matching match trails vs. no-match trials
- How does the time required to perform Task 2 compare with the time required to perform Task 3 with matched and unmatched trials?
- How does time to perform each task differ across blocks?
- How does errors to perform each task differ across blocks?
- Did the experimental results and your predicted results match? If not, develop a plausible reason to explain why.
- Do you think one’s reaction time can be improved? Did your reaction times improve in the tests you performed?
