Scenario 1: The stimulus was randomly delivered. The subject used their dominant hand.

Scenario 2: The stimulus was delivered at a fixed interval. The subject used their dominant hand.
Scenario 3: The stimulus was randomly delivered. The subject used their non-dominant hand.
Scenario 4: The stimulus was delivered at a fixed interval. The subject used their non-dominant hand.

In a fifth experiment, the stimulus was visual. Subjects were directed to press a button in response to the visual signal.

Scenario 5: The stimulus was randomly delivered. The subject used their dominant hand.

Predict outcomes for scenarios 1-4.

Will the response time be shorter for a randomly delivered stimulus or a stimulus delivered
at fixed intervals? Explain the rationale for your prediction.
Will the response time be shorted for the dominant hand or the non-dominant hand?

Explain the rationale for your prediction.
Predict the outcome for scenario 1 and scenario 5. Will the response time be shorter for an auditory stimulus or a visual stimulus? Explain the rationale for your prediction.

1. Try to Make a scientific figure. Use the Biology department's Guide to Making Figures, posted under Learning Materials, do one figure showing the means of all five experiments. You may prepare your figure by hand on graph paper

2 . Describe how different pairs of experimental means compare with each other - are they similar or different; If the means are different, how are they different? Do not try to explain why some means are similar and/or other means are different, just describe pairs of means.
