5. Reaction Time (RT)
Interval of time between the moment that a stimulus is presented to when a response is initiated.
Indicative of the amount of time needed to prepare a response.
Influenced by several factors.

6. Number of Response Choices
Simple vs. choice RT
Hick’s Law
Relationship between the number of movement choices and the time needed to prepare a response
The higher the degree of uncertainty in a given situation, the longer the time needed to decide which response to make
