The conference heard that dolphins are self-aware – they can recognise themselves in the mirror.
Minor thing, but I absolutely despise that recognizing yourself in a mirror is considered a measure of self awareness.
There's a bit more research into that than they let on in the general-purpose news article. That test is also pretty much the best that we've got right now. So many species fail that test, which means that we can focus on refining to what degree are the species that succeed self-aware, which is a lot harder to figure out.
Yeah, but how is recognizing yourself in a mirror a test of self awareness to begin with? It sounds more like a test of visual perception.
True, an assumption is made that we can see the same image on the mirror that any other animal sees. However, if that assumption holds true, then when, say, a parrot looks at the mirror, gets confused, and pecks at what it should recognize as itself (not from ever having seen itself, but because it should recognize that its actions are the same as those on the mirror), then the parrot is probably not 'self-aware' in the terminology that is used to judge intelligence.
A better test would be to kick an animal, and see if the animal cares or not. If it doesn't like being kicked, it probably is somewhat aware of itself.
Not necessarily. Even plants react to external stimuli, but they have no central nervous system. Animals are just able to verbalize it and perhaps retaliate. It is aware that it is experiencing external stimuli that its instincts determine to be hostile or at least unfavorable. Perhaps, though, this is simply a difference in the conceptualization of the term "Self-aware."
I would argue against the term 'higher intelligence' and similar. It implies that intelligence can be effectively compared on a linear scale, which I object to heavily.
Not necessarily. Such terminology is used to broadly define self-awareness, language, spacial recognition, etc. Are you saying that because it's such a blanket-term, it gives the impression that species are either "not intelligent at all" or "highly intelligent"?
