Fig. 5. The distribution of the HP distances and the
angles of the
Orienting (blue circle) Avoidance (red square) and No (green triangle)
Responses of all animals tested. (AD) Isolate and dominant animals
displayed Orienting Responses. While separated
(A,Bisol,Ddom), while paired (Bdom) and while
separated by an open divider (Cdom), most isolate and dominant
animals displayed Orienting Responses, although some Avoidance Responses and
No Responses were also produced. Note that the Avoidance Responses produced by
the isolate and the dominant animals have a small HP distance value (<1).
(C) Subordinate animals displayed Orienting Responses when separated but
displayed Avoidance Responses when interacting with dominant opponents. The
subordinate animals produced Orienting Responses while separated on Day 1
(Asub) similar to the isolate and the dominant animals. While
paired (Bsub), the subordinate animals showed Avoidance Responses.
Note that the Avoidance Responses produced by the subordinates have a large HP
distance value (1<HP distance value<2.5). In a semi-separated condition
(Csub), some subordinate animals showed Orienting Responses whereas
other subordinate animals continued to show Avoidance Responses and large HP
values. While separated on Day 2 (Dsub), most subordinate animals
showed Orienting Responses, while three subordinate animals produced Avoidance
Responses with large HP values (>1).
