Q

Displacement Behavior

A

Occurs when frustration arises as a result of not being able to complete a simple highly motivated behavior. This resulting abnormal behavior IS NOT related to the originally motivated behavior and is irrelevant to the situation in which it appears.

Ex. Destructive behavior / Polydipsia / Sexual Behavior / Excessive grooming

Q

Vacuum Behavior

A

Results from frustration of the inability to express a highly motivated behavior. The abnormal behavior IS relevant to the source of frustration but is performed without the appropriate stimuli or environmental conditions.

Ex. Chewing air - Giraffes

Q

Stereotypic Behavior

A

Behavior that is repetitive, invariant (done EXACTLY the same way each time) and has no obvious function. Vacuum and displacement behavior can become stereotypic if not solved.

Q

Two hypotheses of stereotypic behavior

A

Behavioral Needs Function:
- A behavior that is genetically programmed and is not responsive to the changing demands of Captivity (ex. Bird has to migrate even if it has plenty food and shelter in captivity)

Reward Function:
- The repetitive nature of the behavior and release of rewarding opioid soothes the stressed animal and is very reinforcing.
