Tovrard a Multidimensional View of Personality and Health

Health status has in effect become an external criterion for various personality traits. It seems unlikely, however, that a unidimensional approach to personality actually will be productive, even when something as concrete as physical health serves as a criterion variable. Instead, the benefits of a more multidimensional, contextualized approach to the prediction of health status are emphasized. Additional comments concern the distinction between cooccurence and correlation of two variables, some ambiguities regarding the appropriate criterion variables for health psychology, and some logistical issues in the domain of personality and health psychology.     

Decision-Making in Married and Unrelated Couples

The decision-making performance of 20 married and 20 synthetic couples, all college students, was compared using the Ferreira-Winter Questionnaire technique. Married couples showed (a) greater spontaneous agreement with each other prior to conjoint discussion, (b) less politeness, (c) more intrusive interruptions, and (d) a lesser exchange of explicit information between husband and wife. Although married couples arrived at more "democratic" or representative decisions in a faster time, this was due to their greater degree of prior shared values and interests. The effects of the history and context of the relationship between subjects upon their pattern of communication and possible contrasts between normal and abnormal couples are discussed.     

Left-handers show greater test-retest variability in auditory and visual asymmetry

Left-right difference scores were analyzed for groups left- and right-handed subjects administered the same dichotic listening and visual half-tests on four separate days. The left-handed subjects showed greater test to test variability than the right handers for both modalities.     

Team-Track: A tool for investigating tracking performance in teams

Team performance and coordination have gained considerable interest in disparate fields (e.g., aviation, process control, medicine, and wartime operations). Team-Track, a C program that allows controlled experimental manipulation of team conditions, was developed to meet the research needs resulting from this interest. Using Team-Track, one can manipulate task interdependence, team staffing, relative contributions of team members, communications, and informational displays in a low-cost environment. The dependent measure of performance generated by the program is the absolute tracking error along each dimension. The program is ideal for investigating team interactions as it allows for orthogonal manipulation of team variables, therefore accommodating a multitude of research paradigms.     

INTERRESPONSE TIME STRUCTURES IN VARIABLE-RATIO AND VARIABLE-INTERVAL SCHEDULES

The interresponse-time structures of pigeon key pecking were examined under variable-ratio, variable-interval, and variable-interval plus linear feedback schedules. Whereas the variable-ratio and variable-interval plus linear feedback schedules generally resulted in a distinct group of short interresponse times and a broad distribution of longer interresponse times, the variable-interval schedules generally showed a much more continuous distribution of interresponse times. The results were taken to indicate that a log survivor analysis or double exponential fit of interresponse times may not be universally applicable to the task of demonstrating that operant behavior can be dichotomized into bouts of engagement and periods of disengagement.     

Caregiver Involvement in the Intensive Mental Health Program: Influence on Changes in Child Functioning

We examined behavioral markers of caregiver involvement and the ways in which family participation was related to treatment outcomes in 47 elementary school children with SED enrolled in a school-based intensive mental health program. Measures of caregiver involvement included therapeutic home visits, attendance at therapeutic meetings, completion of ratings on the daily point sheet, and extra communications with the therapeutic team on the point sheet. Greater initial impairment was associated with greater caregiver involvement. Greater caregiver involvement was linked to improvement in child thought processes, increased ability to provide emotional and social supports for the child, and greater overall child functioning at discharge. Our findings also reflected increased therapists’ attempts to provide additional in-home services in cases where caregivers demonstrated a decline in their ability to provide for their children’s physical and material needs, or in which therapists discovered that the family functioning was more impaired than what was initially assessed. We provide a case study that exemplifies many of these findings.     

Life Trajectories, Genetic Testing, and Risk Reduction Decisions in 18–39 Year Old Women at Risk for Hereditary Breast and Ovarian Cancer

This qualitative study identified four life trajectories that influenced the decision in young women to have genetic testing for mutations in BRCA1/2 and subsequent risk reduction decisions after receiving a positive mutation result. Fifty nine women between the ages of 18–39 years were interviewed in this grounded theory study, 44 of those tested were found to have a mutation in either BRCA1 or BRCA2. Of those with a mutation, 23 had no history of cancer and 21 had a breast cancer diagnosis. Analysis of the 44 participants tested found that risk reducing decisions were related to the life trajectories that preceded genetic testing. These life trajectories included: 1) Long-standing awareness of breast cancer in the family, 2) Loss of one’s mother to breast cancer at a young age, 3) Expression of concern by a health care provider, and 4) Personal diagnosis of breast cancer. Understanding possible influences behind decision making for genetic testing and risk reduction in young women may assist health care providers in offering age appropriate guidance and support.     

Neither Mereology nor Magic,but Teleology

Contemporary theories of universals have two things in common: first, they are unable to account for necessary connections between universals that form a structure. Second, they leave teleology out of their accounts of instantiation. These facts are not unrelated; the reason why contemporary theories have such trouble is they neglect the ancient idea that universals are ends at which nature aims. If we want a working theory of universals, however, we must return to this idea. Despite its unpopularity among realists, teleology is not a disposable eccentricity, and its dismissal is not an improvement on ancient views.
