Hypothesis:

The fact that each hemisphere of the brain corresponds to the opposite side of the body has lead our group to believe that there will be a deay in reaction time depending on the position of the body that is being stimulated and the side of the body that is reacting to it. The reponse time should be longer when the side of the body that is being stimulated, hit with the hammer, is also the side of the body that is the reaction to it, the hand that presses the button.

Conclusion:

We found that the whole theory of the alternative hemisphere that we initially predicted was partially correct. When we stimulated the left leg and had the right arm react to it it did so much more quickly than if this occured on the same side of the body. We only had some information that supported this idea but if this experiment were repeated with more trials, the outcome would be more accurate and render a more conclusive result.
