A gestural repertoire of 1- to 2-year-old human children: in search of the ape gestures.

abstract：:Fish move in a three-dimensional environment in which it is important to discriminate between stimuli varying in colour, size, and shape. It is also advantageous to be able to recognize the same structures or individuals when presented from different angles, such as back to front or front to side. This study assessed ...
