Abstract
Kelly's attempt to derive apparently motiwtional phenomena (hostility, guilt, etc.) solely from the confirmation or disconfirmation of personal constructs cannot adequately explain such phenomena. His account of hostility assumes that some beliefs are so resistant to change that the person seeks to compel confirmation of them; however, this resistance is incompatible with Kelly's own Choice Corollary. Anxiety is said to derive from the fact that disconfirmation would leave one's world in chaos, but “chaos” is shown to be an illogical concept. Humor, in turn, cannot be explained just by cognitive incongruity, since incongruity may as well lead to anxiety or hostility. Finally, guilt cannot be explained without reference to underlying fears of punishment and their rationalization in terms of supposedly objective moral concepts. Nevertheless, Kelly's Repertory Grid technique, supplemented by laddering, may be useful in indicating primary needs, moral convictions, and sources of anxiety.
