Dealing primarily with human motivation, this compact volume-an edited collection of articles-presents selections from the important personality theories of Sigmund Freud, William McDougal, Gordon Allport, Henry Murray, David McClelland, Abraham Maslow, Leon Festinger, and Julian Rotter. The selections take up topics such as instincts; the manner in which motives effect the behavior of human beings, and the attributes of the motivational constructs which set them apart; the motivational process through encounter with the environment; and the effects of experience, with situations as a key variable in permitting the prediction of behavior which we customarily call motivated.
