Chameleon’s colour shifting is strategic and directed by lizard’s mood just the same way human beings react towards “outside intrusion”. As the matter of fact, the influence of a mood has an immense impact upon human’s behaviour and judgment. The way society members process incoming information and extend at which they tend to mimic others highly depends on a state of the mood.
Recent researches demonstrate that apparently positive mood signals that environment is safe and therefore one is more likely to rely on “existing knowledge structures, such as stereotypes” 1) and “adopt automatic behaviours” 2). While negative mood creates a feel of uncertainty and necessity “to be on guard” 3) which leads to individual being less easily influenced by other’s behaviour and mimicry tendency getting reduced.
