Participants' understanding of the process of psychological research: informed consent

Sixty-five undergraduates participating in a wide range of psychological research experiments were interviewed in depth about their research experiences and their views on the process of informed consent. Overall, 32% of research experiences were characterized positively and 41% were characterized negatively. One major theme of the negative experiences was that experiments were perceived as too invasive, suggesting incomplete explication of negative aspects of research during the informed consent process. Informed consent experiences were viewed positively 80% of the time. However, most of the participants had a limited view of the purpose of informed consent: less than 20% viewed the process as a decision point. Results suggest a number of common pitfalls to standard informed consent practices that have not generally been recognized. Results are discussed in terms of both ethical and methodological implications. Suggestions for improving the informed consent process are also provided.     

EDMUND D. PELLEGRINO's PHILOSOPHY OF FAMILY PRACTICE

Family medicine has grown as a specialty from its early days of general practice. It was established as a Board Certified specialty in 1969. This growth and maturation can be traced in the philosophy of family medicine as articulated by Edmund D. Pellegrino, M.D. Long before it was popular to do so, Pellegrino supported the development of family medicine. In this essay I examine the development of Pellegrino's philosophical thought about family practice, and contrast it to other thinkers like Ian McWhinney, Kerr White, Walter Spitzer, Donald Ransom, and Hebert Vandervoort. The arguments focus on whether the goals of family medicine and family practice (possibly two distinct entities) can be articulated, especially considering the definitional problems of “family” and “community.” I conclude by echoing Pellegrino's hope that family medicine can contribute a fresh alternative to isolated, individualistic and technological thinking in medicine.     

Critical importance of exposure duration for affective discrimination of stimuli that are not recognized

Previous research has found that repeated exposure to briefly presented visual stimuli can increase the positive affect for the stimuli without enhancing their recognition. Subjects could discriminate target and distractor shapes by affective preference in the absence of recognition memory. This study examined this phenomenon as a function of stimulus exposure duration. Over exposure durations of 0, 2, 8, 12, 24, and 48 ms, the functions for affect and recognition judgments exhibited different temporal dynamics. Target selection by affect was possible at very brief exposures and was influenced little by increasing durations; target selection by recognition required longer stimulus exposures and improved with increasing durations. Affective discrimination of stimuli that are not recognized is a reliable phenomenon, but it occurs only within a narrow band of time. This parametric study has specified the relationship between exposure duration and affect and recognition judgments and has located that temporal window.     

The importance of primary care for theoretical medicine: A commentary

Froom and Froom all attention to referral bias as a frequent cause for misinterpreting the medical literature. This is particularly a source of false certainty, and therefore false science, in U.S. practice, where referral centers are often seen as the only legitimate source of medical knowledge and where primary care is discounted as a source of scientific observations. Appreciation of the primary care setting is therefore a critical element in theoretical understanding of medical epistemology.     

An in-home investigation of maternal teaching strategies during Sesame Street and a popular situation comedy

A naturalistic in-home investigation of maternal teaching strategies while viewing an educational program (Sesame-Street) and an entertainment program (a situation comedy) was conducted. Fourteen mothers and their pre-school children tape-recorded their coversations while jointly viewing the two television programs. Mothers tooks the role of teacher during both types of programs, but they talked more and asked proportionally more questions about the content of Sesame Street than they did about the content of the situation comedy. Likewise, during Sesame Street, mothers talked more about educationally relevant concepts such as size, color, and number. Children, while watching Sesame Street, engaged in ore labeling of educationally relevant concepts than they did while viewing the situation comedy. During the situation comedy, mothers explained why television characters performed particular behaviors and assigned traits and emotions to characters more frequently than they did during Sesame Street. The findings suggest that the parent may play an important role in helping children maximally utilize television as a teacher.     

Aging and Family Personality: A Developmental View

The dramatic numerical and proportional increase in the elderly population has important implications for family dynamics and the family life cycle. This paper considers some of the issues of aging, death, loss, and separation, as they relate to individual and family development and to shifting roles and responsibilities of family members.
