Investigations of personality may be focused upon any one of three
different levels of phenomena. The first is the level of traits,
interests, attitudes, or sentiments considered as composing an "inner"
personality; the second is the level of behaviour and expression; the
third is the level of impression, the perception and interpretation of
behaviour by another. Since a discovery on one of these levels
establishes a presumption that the phenomenon in question has some
counterpart on the other levels, a problem which is elusive on one plane
may often be more expediently attacked on another. This is the motive
and the plan behind the present study. Instead of approaching the
difficult problem of consistency or organization in personality through
a study of "inner" dispositions-which, of course, can only be known
indirectly through tests and scales, -we have chosen to refer the
problem to the level of expressive movement and there to examine it in a
more direct fashion.
