Chase

Overview and Meaning

Chase is included in the flight and submissive behavior category. However, it may result in an agonistic interaction.

Description

A mouse will chase a fleeing partner. No biting occurs.

Classification

Contexts

Flight and submissive behavior are seen in three distinct contexts, and have quite different meanings, both for the mouse and for the observer's correct interpretation of the behaviors: 

  1. In response to threat behavior, an animal may attempt to flee and may or may not be pursued (chase behavior) by the animal performing the threat behavior. Alternatively an animal may perform submissive behaviors immediately. In either case the agonistic interactions are terminated immediately, and the animal fleeing or submitting has indicated its subordinate dominance status to the animal performing the threat behavior. Such interactions are classified as mediated aggression.
  2. In contrast, if an animal performs retaliation behavior it is challenging the dominance of an animal performing a threat. The resulting escalated aggression is also terminated by flight and submissive behavior. However the meaning is quite different - indicating which mouse has lost the particular fight, not necessarily which mouse is dominant in a stable uncontested hierarchy.  
  3. Fleeing and withdrawal can also occur in response to any threatening stimulus, be it social, predatory (e.g. when mice flee from human handlers), or abiotic (e.g. when mice withdraw from a brightly lit open space). Fleeing and withdrawal are viewed as evidence of aversion, anxiety, and/or fear.

Flight and submissive behaviors are part of

Agonistic Interactions

The full behavior chain consists of:

  1. Threat behaviors
  2. Aggressive behaviors
  3. Flight and submissive behaviors
  4. Defensive behaviors

Agonistic interactions occur to assert territory or dominance. This can proceed as either mediated aggression or escalated aggression, differentiated by the absence or presence of aggressive behaviors.
