In a recent study, Orr and Lanzetta (1984) showed that the excitatory properties of fear facial expressions previously described (Lanzetta & Orr, 1981; Orr & Lanzetta, 1980) do not depend on associative mechanisms; even in the absence of reinforcement, fear faces intensify the emotional reaction to a previously conditioned stimulus and disrupt extinction of(More)
Previous research has demonstrated that particular facial expressions more readily acquire excitatory strength when paired with a congruent unconditioned stimulus than when paired with an incongruent outcome. The present study extends these findings on the excitatory and inhibitory role of facial expressions by demonstrating that particular facial(More)
This investigation tested the hypothesis that congruity of a facial affective expression with an aversive outcome as compared to incongruity of an expression and outcome would result in superior differential conditioning of an autonomic response (skin conductance) to the facial expression. Using a differential conditioning paradigm with slides of fear faces(More)

1 " I believe that discussion or application of game theory is utterly meaningless without a proper interpretation. This task cannot be left entirely to philosophers of science, for it constitutes the very essence of the theory. " ~ Ariel Rubinstein (1991) " In analyzing games the theory does not assume rational behavior; rather it attempts to determine(More)
Two groups of Vietnam veterans--Post-traumatic stress disorder (PTSD, n = 17) and non-PTSD (n = 80)--were developed from a sample of treatment-seeking alcohol abusers. The subjects completed a Combat Experiences Questionnaire, a PTSD Symptom Scale, the MMPI, and the Multidimensional Personality Questionnaire (MPQ). The MPQ proved to be a useful adjunct to(More)
