Mirror self-recognition in the bottlenose dolphin:
A case of cognitive convergence
What was done?
An experiment was performed on two dolphins one was 13 years old male Bottlenose dolphin and other was 17 years old male bottle nose dolphin. This experiment was performed to see if there is any ability in dolphin to use the mirror to inspect any marked part of the body and to prove whether they have self- recognition ability in them or not.
How it was done?
Two dolphins were kept in the pool for long time and when the research was being done everything was video recorded and been judged and given score by people who were not aware of this research project to come to a decisive conclusion. This was two phase experiment which was done in same location, …show more content…
This session was conducted in two connected pools, large and a small pool. Mirror was stationed near the mouth of connected smaller pool.
Subject one experiment:- 16 non-marked pre-feeding control sessions and during the post-feeding sessions consisting of 8 marked condition with the mirror sessions, 5 marked condition with a covered mirror or no mirror sessions, 7 unmarked condition with the mirror sessions, 9 unmarked condition with no mirror sessions, and 1 sham-mark condition with mirror session (Directly from the review article).
Subject two experiment:- 20 non-marked pre-feeding control sessions and during 11 post-feeding sessions consisting of the marked (or sham-marked) condition with the mirror, 5 marked (or sham-marked) conditions with a covered mirror or no mirror, and 4 unmarked (or no sham-mark) conditions with the mirror. Thus, 16 mark or sham-mark sessions were conducted in this phase (Directly from the research …show more content…
What the result(s) or the outcome was (were)?
Outcome for Phase 1:- The animals spend more time engaging in to self directed behavior at reflective surface like walls when they are marked than they are early sham-marked late sham-marked. Also dolphins spent more time in mark-directed behaviors at reflective surface when they are marked and spent less time in sham-marked directed behavior when they are sham-marked.
Outcome for Phase 2:- The researcher’s didn’t came to any conclusion for this and had to do experiment with two different subjects, but they made 3 predictions:-
1. Dolphins should show no social behavior at the mirror.
2. Dolphin’s should spend more time at the mirror when marked than any other conditions like sham-marked or unmarked.- They confirmed this prediction when they did this part of experiment with second subject
3. Dolphins goes directly to the mirror when they are marked and if they didn’t left the session before self recognition period starts than when they are
