The authors describe a cognitive-behavioral model for coping with stress that counselors can use as the basis for family assessment and personalized intervention. The model, assessment procedures, and appropriate counseling strategies are discussed. Translation of the model into clinical practice is examined with families of handicapped young children. A brief case study is provided to illustrate the model's usefulness for counselors.  相似文献

As a result of Freud's ambiguity (and that of later analysts) regarding the nature of the superego and how to treat it in clinical practice, it has taken many years and many theoreticians to move from Freud's predilection to use it for purposes of "suggestion" in overcoming resistance, toward the concept of the superego as part of the ego's hierarchically mobilized defensive activities in the analytical process. Although much ambiguity persists, an attempt is made here to reduce it so that analytical technique may move forward to allow the superego to be analyzed as an unconscious conflict solution.  相似文献

By his introduction of the term "psychisches Trauma", Strümpell exerted an influence on Oppenheims concept of traumatic neurosis. What he termed "Begehrensvorstellungen", too, had an important part to play in the ensuing discussion on the origin of traumatic neuroses. That the two sides in dispute nonetheless appealed to the authority of the internist and neurologist Strümpell in matters of expert opinion, is an indication of his discernment in these problematic open questions.  相似文献

Invariance in the MMPI's component structure   总被引:1,自引:0,他引:1  
Bernstein and Garbin (1985b) suggested that the Minnesota Multiphasic Personality Inventory's major clinical scales (excluding Scales ? and 5) can be approximated by an oblique three-component structure: (a) Profile Elevation, (b) Test-taking Attitudes, and (c) Optimism-Pessimism, collectively termed the salient weight model. In this study, we found that both this model and the MMPI's principal component structure remain invariant across race, sex, and, as previously noted, context of testing (job applicants vs. inmates in correctional institutions). We further noted that several alternative definitions of Profile Elevation provide equally satisfactory representation of the relations among the scales. This factor invariance is necessary, but not sufficient, for the MMPI to be viewed as unbiased.  相似文献

This study examines the ability of five self-report assessment measures to predict college students' drug use across 12 pharmacological drug categories. Subjects were 125 female and 61 male university undergraduate students. The test battery included the following instruments: the Psychopathic Deviancy (Pd) scale of the Minnesota Multiphasic Personality Inventory (MMPI); the MacAndrew Alcoholism scale (MAC), a special scale of the MMPI; the Sensation Seeking Scale (SSS); the Millon Alcohol Abuse Scale; and the Millon Drug Abuse Scale. Scores from these instruments were utilized in linear combinations to predict individual drug use outcomes as well as polydrug versus single drug use patterns. The drug categories included in this investigation are coffee, tobacco, alcohol, marijuana, tranquilizers, depressants, amphetamines, LSD, other hallucinogens, solvents, narcotics, and cocaine. Results demonstrate significant and meaningful relationships between predictors and drug use levels among college students. Weighted equations derived from linear discriminant function analyses were generally capable of accurately classifying subject's drug use levels across drug categories and in discriminating single drug use from polydrug use patterns. Typically, the Sensation Seeking Scale entered as the most powerful predictor of substance use and abuse.  相似文献

The perception of continuous curves in dot stimuli   总被引:1,自引:0,他引:1  
J T Smits  P G Vos 《Perception》1987,16(1):121-131
Two categorisation experiments are reported in which the perceptual phenomenon that some simple arrays of discrete dots appear as a continuous curve whereas others are perceived as an angular contour or as consisting of separate groups of dots was investigated. Triplets of dots were presented in the first experiment, and complete or incomplete regular dot polygons (ie dots positioned on the vertices of imaginary regular polygons) in the second. In both experiments the perception of a curve versus an angle was determined mainly by the relative orientations of the dots, ie by the angles between successive virtual lines, whereas the lengths of the virtual lines had relatively little influence. In experiment 2 the number of displayed dots was shown to be a second independent factor for perceiving continuity. These results are in agreement with results from experiments on dipole textures discrimination, and suggest the psychological existence and importance of virtual lines in the visual processing of dot stimuli.  相似文献

After inducing hostility toward a confederate by threatening subjects' self-esteem, subjects were then given the opportunity either to deliver shocks (Experiment 1) or to withhold rewards (Experiment 2) from their confederate. Physiological measures were taken prior to the hostility induction, shortly after the induction and, finally, after the opportunity to aggress. Measures of individual differences relating to aggressive behavior were also considered. While the experimental manipulation was the best predictor in the ‘withholding rewards’ condition, measures of dissipation-rumination tendencies and emotional vulnerability were the best predictors in the ‘shock administration’ condition. In both conditions, systolic blood pressure seemed to reflect differences in arousal as a function of the hostility induction procedure, while subjects in the withhold rewards procedure also showed a decrease in systolic pressure after having an opportunity to aggress toward the confederate. It was concluded that not only is the withholding of rewards a more ethically acceptable procedure than shock administration, but it is also more likely to reflect experimental rather than individual difference affects.  相似文献
