An avoidance response is a response that prevents an aversive stimulus from occurring. It is a kind of negative reinforcement . An avoidance response is a behavior based on the concept that animals will avoid performing behaviors that result in an aversive outcome.
Drugs that are considered to show antipsychotic-like effects selectively suppress the avoidance response without affecting escape behavior. [4] [1] [2] [5] Conversely, drugs that are not considered to have antipsychotic-like effects either have no effect in the CAR test or suppress both avoidance behavior and escape behavior at the same doses.
Methodologically, a "Sidman avoidance procedure" [10] is an experiment in which the subject is periodically presented with an aversive stimulus, such as the introduction of carbon dioxide or an electric shock, unless they engage in a particular response, such as pulling a plunger, which delays the stimulus by a certain amount of time.
Excessive avoidance has been suggested to contribute to anxiety disorders, leading psychologists and neuroscientists to study how avoidance behaviors are learned using rat or mouse models. [1] Avoidance learning is a type of operant conditioning (also known as instrumental conditioning).
In free-operant avoidance a subject periodically receives an aversive stimulus (often an electric shock) unless an operant response is made; the response delays the onset of the shock. In this situation, unlike discriminated avoidance, no prior stimulus signals the shock. Two crucial time intervals determine the rate of avoidance learning.
Avoidance reaction is a term used in the description of the movement of paramecium. This helps the cell avoid obstacles and causes other objects to bounce off of the cell's outer membrane . The paramecium does this by reversing the direction in which its cilia beat.
Modal impact hammer with interchangeable tips and accompanying temporal and frequency responses. An ideal impact to a structure is a perfect impulse, which has an infinitely small duration, causing a constant amplitude in the frequency domain; this would result in all modes of vibration being excited with equal energy.
Mode effect is a broad term referring to a phenomenon where a particular survey administration mode causes different data to be collected. For example, when asking a question using two different modes (e.g. paper and telephone), responses to one mode may be significantly and substantially different from responses given in the other mode.
