Contrasting Approaches in Marital Counseling

My Aim in this paper is to look at the therapist-marital couple relationship as a social system, and from this perspective to outline some aspects of the difference between treating a husband or wife as an individual patient and treating them together as a marital couple.
I will try to differentiate individual treatment and treatment of the marital pair on two dimensions: their respective use as sources of data about the marital relationship, for both therapy and research, and their potentialities for changing the marital interaction.     

Evoked potentials and stages of information processing: Methods of analysis

The use of principal components analysis (PCA) for the study of evoked-response data may be complicated by variations from one trial to another in the latency of underlying brain events. Such variation can come from either random intra-and intersubject variability or from the effects of independent variables that are manipulated between conditions. The effect of such variability is investigated by simulation of these latency-varying events and by analysis of evoked responses in a behavioral task, the Sternberg memory search task, which is well known to generate variation in the latency of brain events. The results of PCA of within-subjects differences in these two situations are plausibly related to underlying stages of information processing, and the technique may augment reaction time data by providing information on the time of occurrence as well as the duration of stages of information processing.     

Body Image Testing System: A microcomputer program for assessing body image

An interactive computer program, the Body Image Testing System (BITS), was developed to assess different components of the body image construct. The BITS program displays a frontal and side view of a human body. Subjects can change the size of each of nine body parts independently (face, neck, shoulders, arms, chest, breasts, stomach, hips, and thighs). Subjects interact with the program until satisfied that the image created matches the instructions. Subjects also provide satisfaction ratings for the nine body segments. To validate BITS, a variety of body image and eating disturbance measures was obtained from over 500 subjects. A factor analysis of actual-ideal differences and a perceptual distortion measure, derived using multiple regression, resulted in five orthogonal factors. Factor 1 measured actual-ideal discrepancy for weight-sensitive body parts. Factor 2 measured the perceptual distortion of weight-sensitive body parts. Additional factors measured perception of face and neck, shoulders, and breasts. The five factor scores plus the satisfaction ratings were strongly associated with actual body size, body fat percentage, and circumference of specific body parts. In addition, there were strong associations between the BITS and other measures of body image. Finally, BITS scores accounted for between 15 and 60% of the variance in measures of eating disturbance.     

Response times for the CAGE,short-MAST,AUDIT, and JELLINEK alcohol scales

The CAGE alcohol screening tool has been touted as a good choice for clinical settings because of its brevity. We administered the CAGE and three other alcohol screening instruments (the Short-MAST, AUDIT, and JELLINEK) by microcomputer to 296 clients at a drinking driver treatment program and three of the four scales to a second sample of 270 clients from six drinking driver treatment programs. The average response times for the CAGE were 31 and 32 sec, respectively, in the first and second samples. The average response time for the JELLINEK was approximately five times longer than it was for the CAGE; response time for the AUDIT averaged four times longer; and response time for the Short-MAST was two and a half times as long. The estimated reliability of the CAGE was the lowest and its standard error of measurement was the highest of the four scales. We recommend the Short-MAST as the tool of choice if the extra minute of administration time it requires in comparison with the CAGE is not critical.     

The Effect of Punishment Probability on Overconsumption and Stealing in a Simulated Commons1

In laboratory simulations of the commons dilemma, overconsumption depletes the shared resource, whereas allowing the players to steal from each other helps preserve the resource since players take from each other rather than from the central supply. In this study, we factorially crossed three levels of punishment probability for overconsumption (0%, 25%, 75%) with three levels of probability of punishment for stealing (0%, 25%, 75%). Subjects (n= 270) in three-person groups harvested points from a slowly regenerating central pool. Results indicated that punishment of overconsumption decreased overconsumption, increased stealing, and helped preserve the commons, whereas punishment of stealing decreased stealing, increased overconsumption, and facilitated depletion of the commons. Rather than punishment of one selfish behavior suppressing the other selfish behavior, a compensatory effect occurred: Punishment of one behavior increased the occurrence of the selfish alternative.     

FROM COLLECTIVISM TO INDIVIDUALISM? THE ACCULTURATION OF GREEK IMMIGRANTS IN AUSTRALIA*

The present study examined whether Greek immigrants in Australia have retained traditional Greek values and behaviours or moved to an integration of these with Anglo-Australian values and behaviours. The sample consisted of Anglo- and Greek-Australian parents and young adolescents and a comparison group of Greeks, resident in Greece. Measures were obtained of values and behaviours considered to be appropriate for family members in the culture. Results showed that Greek-Australians retained the collectivistic values of their Greek culture while Anglo-Australians demonstrated a more individualistic orientation. There was evidence for convergence of Anglo- and Greek-Australian perceptions of appropriate behaviours and thus support for a view that acculturation is more likely to be manifested in behaviours than in core values. Although there were some differences in expressed values and behaviours, overall there was little evidence for a cultural gap between Greek-Australian parents and their adolescents.
