List the three primary laws of reflex (44,3-5)
Law of threshold
At very weak intensities a stimulus will not elicit a response, but there is a point where the stimulus is elicited. There is a point below which no response is elicited and above which a response always occurs.
Law of intensity-magnitude
Describes the relationship b/t the intensity of the elicited stimulus and the size or magnitude of the response. As the intensity of the US increases so does the magnitude of the elicited UR.
Law of latency
Time b/t the onset of the elicited stimulus and the appearance of the reflexive response. As the intensity of the US increases the latency to the appearance of the elicited UR decreases
