Two related attribution theories of motivation are examined One, an intrape
rsonal theory, includes self-directed thoughts (particularly expectancy of
success) and self-directed emotions (pride, guilt, and shame). The second i
s an interpersonal theory and includes beliefs about the responsibility of
others and other-directed affects of anger and sympathy. These two theories
are respectively guided by the disparate metaphors of the person as a scie
ntist and the person as a judge. Some experimental evidence supporting the
conceptions and the range of phenomena that they incorporate are examined.
