Measures of conditioned emotional response are used by researchers in classical conditioning experiments to assess the conditioned emotional response in subjects.

## Movement ratioEdit

The movement ratio is the proportion of time during the presentation of a conditioned stimulus that the subject is displaying elicited behavior. Movement ratio is defined as

$MR = Tb / Tt$

Where MR = Movement Ratio, Tb=Time displaying the elicited behavior and Tt = Total time of CS presentation

## Suppression ratioEdit

The suppression ratio is equal to the response rate during a CS presentation divided by the sum of response rate during the CS plus the response rate in the period immediately preceding the CS. In other terms:

$SR = D / (D+B)$.

Where SR = Suppression Ratio, D = Responding during CS and B = Responding before CS.
