Sexual arousal and interpersonal evaluations

In an attempt to reconcile conflicting results concerning the effects of sexual arousal on interpersonal evaluations, hypotheses based on adaptation level, arousal-need gratification, and labeling of arousal explanations were tested. The variables of sexual arousal, technique of stimulus material presentation, physical attractiveness of the original stimulus female, and physical attractiveness of the final target person being judged were manipulated in a 2 × 2 × 2 × 2 design. A significant three-way interaction (Arousal × Stimulus Attractiveness × Target Attractiveness) obtained on all measures of interpersonal evaluation was interpreted as supporting a labeling of arousal explanation. It is suggested that subjects first interpret their arousal as being caused by their attraction toward the stimulus person. The characteristics of the stimulus person then become a factor used by subjects when they subsequently make judgments of target females. The adaptation-level and arousal-need gratification hypotheses were not supported.     

The effects of observation on emotional arousal and affiliation

This study assessed the influence of anticipated experimenter surveillance during the performance of a painful or potentially embarrassing act on affiliative preferences before engaging in that act. As predicted, there was an overall preference for isolation when the act to be performed was embarrassing, and this tendency increased with anticipated surveillance. There was an overall preference for affiliation under fear arousal, and this preference also increased with anticipated surveillance. Contrary to previous research, whether or not the potential affiliate was a subject in the experiment (i.e., in a similar or dissimilar emotional state) did not affect these tendencies. Possible ways of accounting for these findings are discussed.     

Pain as purgation: The role of pathologizing in the life of the mystic

Since Descartes, man has been defined in terms of body and spirit only. Yet there is a third term that is of crucial importance for the founding of a psychology of suffering. The realm of psyche, or soul, is a middle ground between the spirit and the body in which the psychological forces of one's life find expression. A psychological approach to the anguish of the suffering soul can be found within the writings of the early desert fathers as well as in the paintings of Hieronymus Bosch. The penitent must learn patience in the face of his suffering, before he can experience the joy of spiritual maturity.A famous anchorite came to take counsel on high things with the abbot Pastor, but the old man turned away his head, and the anchorite went away aggrieved. His disciple asked Pastor why he had refused to talk with a man so great and of such reputation in his own country, and the old man said that his visitor could speak of heavenly things, but that he himself was of earth. If he had spoken to me of the passions of the soul I could have answered him: but of the things of the spirit I am ignorant.Mr. Fischer is a member of the Psychology Department, University of Dallas, Irving, Texas 75060.     

Suppression and substitution in the treatment of nailbiting

The effectiveness of a package treatment for reducing nailbiting was studied. The package was composed of both positive procedures aimed at teaching adaptive behavior to substitute for nailbiting and negative procedures aimed at advancing skills for suppressing nailbiting. The design of the study permitted an analysis of the contributions of both positive and negative components of the package. Subjects assigned to combined, positive, negative and placebo groups received four weekly treatment sessions, and changes in their nailbiting behavior were compared with untreated controls. As in previous studies, nonspecific factors such as demand and attention to ones nails were found to be important determinants of outcome. In addition, positive procedures were found to be substantially more important than negative procedures in the maintenance of reductions in nailbiting over a 4-month follow-up period.     

Reaction time measurement errors resulting from the use of CRT displays

Three sources of potential error in reaction time measurement may occur when raster scan CRT displays are used to present stimuli: phosphor persistence, sweep delay, or transmission delay. For most applications, only the third source of error is likely to be significant.     

Statistical significance tests for binormal ROC curves

Statistical significance tests are derived and evaluated for measuring apparent differences between an obtained and an expected binormal ROC curve, between two independent binormal ROC curves, and among groups of independent binormal ROC curves. A binormal ROC curve is described by two parameters which represent the spread of the means and the ratio of the standard deviations of the two underlying Gaussian decision variable distributions. To test the significance of apparent differences between or among ROC curves, approximate χ² statistics for each of the three tests were constructed from maximum likelihood estimates of the two parameters defining the binormal ROC curve. The performance of each test statistic was evaluated by simulating five-category rating scale data with equal numbers of noise and signal-plus-noise trials (set at 50, 250, and 500) for each of three typical ROC curves. For the significance test involving only one ROC curve, rating scale data were generated from the chance diagonal of the ROC space also. Although test performance was found to be somewhat dependent on the number of trials and on the location of the ROC curve in the ROC space, comparisons of the obtained and expected fractions of (falsely) significant results at various α levels showed the proposed statistical significance tests to be reliable under practical experimental conditions.
