===Embodied cognition===
{{main|Embodied cognition}}
The traditional cognition approach assumes that perception and motor systems are merely peripheral input and output devices.<ref>Niedenthal, 2007; Wilson, 2002</ref> However, [[embodied cognition]] posits that the mind and body interact 'on the fly' as a single entity. An example of embodied cognition is seen in the area of robotics, where movements are not based on internal representations, rather, they are based on the robot's direct and immediate interaction with its environment.<ref>Wilson, 2002</ref> Additionally, research has shown that embodied facial expressions influence judgments,<ref>Niedenthal, 2007</ref> and arm movements are related to a person's evaluation of a word or concept.<ref>Markman, & Brendl, 2005</ref> In the latter example, the individual would pull or push a lever towards his name at a faster rate for positive words, than for negative words. These results appeal to the embodied nature of situated cognition, where knowledge is the achievement of the whole body in its interaction with the world.
