|Motion: Motion is a spatial variation of one or more observed or not observed objects in time. Problems arise in connection with attribution or withdrawal of predicates. See also change, temporal identity, process, flux, vectors._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Chris Frith on Motion - Dictionary of Arguments
Movement/cognition/perception/life/Frith: from the way something moves, one can see whether it is a living being or, for example, a leaf.
For example, about 14 light points are attached to the joints of a person. The person then moves in a dark room.
N.B.: if you only look at a single moving point, you cannot see anything sensible in the movement. Even if all 14 points do not move, you cannot see anything sensible! In movements you immediately recognize something sensible. One can even say whether the figure is happy or sad(1).
N.B.: even cats can be trained to recognize a cat from the points, and to recognize when the points are arranged randomly.
Movement/interpretation/objective/intention/Frith: in movements, the internal models are the goals of the action.
Problem: movements are ambiguous, e.g. I can go to the baker next door or to Patagonia.
>Ambiguity, >Goals, >Motivation, >Intention, >Intentionality.
Movement/interpretation: e.g. the person opposite me should repeat everything I do. I raise my left hand, the other raises the right. Is this a mistake?
E.g. I take the right hand and touch my left ear, the other person takes the left hand and touches his/her left ear. Is this a mistake?
N.B.: now to the correct test: in the middle of the table is a big red button. I lean forward and touch it with my forehead. What the other person is doing depends on my hands: if I have chained hands, but the other person does not, he/she will use his/her hands, when I have free hands, the other person will use his/her heads.
Movement/imitation/interpretation/Frith: for example, the subject should move the arm rhythmically up and down while watching another person, moving the arms rhythmically sideways.
This shows that we unconsciously tend to imitate others.
N.B.: when the person moving sideways was replaced by a robot, the unconscious imitation did not happen.
Movement/action/brain/interpretation/Frith: thesis: in case of the robot the brain only registers movements but no actions.
