The ethical ideologies of psychologists and physicians: a preliminary comparison

The ethical ideologies of psychologists (who provide health services) and physicians were compared using the Ethics Position Questionnaire. The findings reveal that psychologists tend to be less relativistic than physicians. Further, we explored the degree to which physicians and psychologists report being influenced by a variety of factors (e.g., family views) in their ethical decision making. Psychologists were more influenced by their code of ethics and less influenced by family views, religious background, and peer attitudes than were physicians. We argue that these differences reflect the varied professional cultures in which practitioners are trained and socialized.     

Human embryonic stem cell therapy

The author presents an overview (completed on September 15, 2001) of three issues involved in the ethics of human embryonic stem cell therapy: the ethical implications of some of the scientific issues involved, the specific ethical issues of the moral standing of the early human embryo and the problem of cooperation, and a consideration of two public policy issues: should the research go forward, and what kind of health care system should the United States adopt. The author argues that the public policy questions are the most important agenda.     

Varying Cautionary Instructions,Monetary Incentives,and Comorbid Diagnostic Training in Malingered Psychopathology Research

In this article, we combine two analogue experiments in which we empirically examined three malingering methodological issues in individuals trained and instructed to simulate posttraumatic stress disorder (PTSD) on the Trauma Symptom Inventory (TSI; Briere, 1995 Briere, J. 1995. Trauma Symptom Inventory professional manual, Odessa, FL: Psychological Assessment Resources.  [Google Scholar]). In Experiment 1, we examined TSI scale effects of the following manipulations using a 2 × 2 design with 330 college students: (a) inclusion or exclusion of cautionary instructions regarding believability of participants' simulation and (b) different financial incentive levels. In Experiment 2, we examined comorbid psychiatric diagnostic training with 180 college students who were either trained to simulate PTSD and comorbid major depressive disorder or trained to simulate only PTSD. Caution main effects were significant for all but two TSI Clinical Scales, incentive main effects and interactions were only significant for one Clinical scale each, and the comorbidity manipulation did not yield any scale differences. We discuss malingering research design implications regarding the use of cautionary instructions, financial incentive levels, and comorbid training.     

Development of Bimanual Skill: The Search for Stable Patterns of Coordination

In 2 experiments, dynamic systems theory predictions concerning intrinsic dynamics and variability of bimanual coordination were examined at different developmental stages. In Experiment 1, ten 4-, 6-, 7-, 8-, and 10-year-old children and adults performed unimanual dominant, unimanual nondominant, and bimanual continuous circle drawing. All tasks were performed at the participants' preferred rate, size, and mode of coordination. The 4-, 6-, and 7-year-old children produced larger circles with longer durations than those of the 8- and 10-year-olds and the adults. That finding demonstrates that younger children display different intrinsic dynamics than older children and adults. The 4-, 6-, and 7-year-old children also displayed more variability in bimanual coordination (more time in less stable patterns of coordination, higher standard deviation in relative phase) and produced more transitions between coordination patterns than the 8- and 10-year-olds and the adults. In Experiment 2, the same participants performed bimanual circles at increasing rates. Consistent with predictions of the HKB model (H. Haken, J. A. S. Kelso, & H. Bunz, 1985), the number of transitions decreased as speed increased. Some support was found for the notion that age-related variables of attention and rate contribute to the increased variability in young children's bimanual coordination.     

Links Between Parents’ and Children’s Levels of Gratitude, Life Satisfaction, and Hope

Decades of research confirm familial links in mental illness, but little is known about the relationships between parents’ and children’s levels of positive emotions. The current study used a past, present, and future framework of positive emotions to explore parent and child levels of gratitude, life satisfaction, and hope. Correlations between self-reported levels of gratitude, life satisfaction, and hope were analyzed in a sample of 148 fourth and fifth grade students and their biological parents (137 mothers, 109 fathers). Findings include statistically significant relationships between (1) mother and child gratitude (but not father and child gratitude) and (2) child life satisfaction and both mothers’ and fathers’ life satisfaction. No significant relationships emerged between parent hope and child hope, although higher parent life satisfaction was associated with higher child hope. Research is needed to investigate the causes of the links identified in the current study.
