Notes from Two Scientific Psychologists: Did language emerge from the neural systems supporting aimed throwing? | Psychology and Brain News | Scoop.it

Aimed throwing is surprisingly uncommon in the animal kingdom. Humans do it par excellence, and otherwise it only shows up occasionally, even in our closest relatives. Chimpanzees will throw things (often faeces) but unlike humans don't throw things when hunting or trying to get food; when non-human animals throw things, it's usually part of a social encounter.

Ape hand gestures reveal where humans evolved language

Ape hand gestures reveal where humans evolved language | Psychology and Brain News | Scoop.it

It is now commonly recognized that high-level cognitive function is not limited to primate lineages and like many other traits, is shaped by selection imposed by ecological and environmental demands. MacClean et al. propose that a merger of the fields of comparative psychology and phylogenetics would greatly improve our ability to understand the forces that drive cognitive evolution

When humans play dead

When humans play dead | Psychology and Brain News | Scoop.it

When a rabbit or other animal is trapped by a predator, it will freeze and assess the situation. It might then flee or attack, what we usually call the "fight or flight response". If that fails, a last-ditch defence mechanism is to go completely immobile, to play dead. Researchers in Brazil now say that in times of grave danger, this same automatic last resort is also exhibited by humans and is experienced as a terrifying feeling of being "locked-in".
