Mirror-induced behaviour in animals
Forštová, Tereza ; Exnerová, Alice (advisor) ; Landová, Eva (referee)
The topic of self-awareness and mirror self-recognition has been more discussed since 1970, when the new procedure named mark test showed the self-recognition in chimpanzees. Although the theory that mirror self-recognition provides evidence of self-awareness is generally accepted, it was showed in the recent studies that it is not necessarily always true, and that the transition between "having self-awareness" and "not having self-awareness" is gradual. There are more mirror tests dealing with mirror self-recognition in animals, such as mirror-mediated spatial location task. Almost all tested species passed well this kind of mirror tests and showed that there was a certain degree of mirror-image understanding. However not all of them show mirror induced self-recognition. There are several reasons of negative results of mark test such as improper methods and procedures applied to particular species, as well as individual differences, e.g. in social isolation and previous experience with mirror. Problems appear in comparative testing of species with different body morphology, e.g. cetaceans, birds, and fish which have forelimbs in form of wings and fins. They are not able to show the same behavioral responses as primates, for which the original mark test was developed. Applied methods should be always...

Selfrecognition, selfawareness and other cognitive functions in cetaceans
Jachnická, Kristýna ; Šimková, Olga (advisor) ; Adamová, Dana (referee)
Self recognition is highly discused topic in cognitive sciences. Experiments on a level of behavioral (mirror test, reference tests of body parts using) show that animals usually are able to realize parts of their own body. There are several experimental evidence among cetaceans of this kind that proved that they are conscious of their own body parts (self awareness). There are also many other complex cognitive skills that can be predisposition to self recognition or that can prove that cetaceans are conscious of they own mind (self consciousness).
