social interactions

Show Summary Details

Quick Reference

The result of an animal reacting to stimuli provided by another member of the same species. In some cases these stimuli may be relatively simple sign stimuli, as in the defence of territory by sticklebacks (Gasterosteus aculeatus) (the red breast of the rival male is the sign stimulus) and the feeding of nestlings by songbirds (distinctive markings within the gape provide the sign stimuli). In other cases the stimuli may be more subtle and complex, requiring some learning or cognition on the part of the participants, as in some cases of dominance and deceit.
