Respecting difference and moving beyond regulation: tasks for U.S. bioethics commissions in the twenty-first century

This article focuses on two possible missions for a national bioethics commission. The first is handling differences of worldview, political orientation, and discipline. Recent work in political philosophy emphasizes regard for the dignity of difference manifested in "conversation" that seeks understanding rather than agreement. The President's Council on Bioethics gets a mixed review in this area. The second is experimenting with prophetic bioethics. "Prophetic bioethics" is a term coined by Daniel Callahan to describe an alternative to compromise-seeking "regulatory bioethics." It involves a critique of modern medicine. In the contemporary context, the areas of biotechnology and access to health care cry out for prophetic attention. The Council has addressed biotechnology; unfortunately, that experience suggests that the kind of prophecy that it practices poses risks to conversation. With regard to access issues, the article proposes an effort that unites themes of human dignity, solidarity, and limits in support of reform, while highlighting, rather than papering over, differences.     

Investigator ratings of ADHD symptoms during a randomized, placebo-controlled trial of atomoxetine: a comparison of parents and teachers as informants

This study compared investigator ratings of ADHD symptoms based on interviews with parents and teachers during a doubleblind, placebo-controlled study of atomoxetine. Investigators completed the ADHD Rating Scale: Investigator (ADHDRS-I) based on separate semistructured interviews with the primary caretaker and teacher of the participant. Interviews were conducted at Visits 2 to 7 during a double-blind treatment protocol comparing atomoxetine (N= 10) and placebo (N= 6). Both parent and teacher-based ratings were sensitive to change in ADHD symptoms with atomoxetine treatment. Parent-based assessment differentiated significantly between treatment with atomoxetine and placebo, whereas teacher-based assessment was less sensitive to change. Parents and teachers showed good agreement on change in ADHDRS-I scores. Investigator ratings based on parent- and teacher-report were sensitive to change in symptoms of ADHD during treatment with atomoxetine. Despite good agreement between parent- and teacher-based ratings of symptom change, parent-based ADHD symptom ratings are more sensitive to symptom change.     

Chimpanzees remember the results of one-by-one addition of food items to sets over extended time periods

Four chimpanzees were highly accurate in selecting the larger of two concurrent accumulations of bananas in two opaque containers over a span of 20 min. One at a time, bananas were placed into the containers, which were outside the chimpanzees' cages. The chimpanzees never saw more than one banana at a time, and there were no cues indicating the locations of the bananas after they were placed into the containers. The performance of these animals matched that of human infants and young children in similar tests. The chimpanzees were successful even when the sets to be compared were sufficiently large (5 vs. 8, 5 vs. 10, and 6 vs. 10) to cast doubt on the possibility that the chimpanzees were using an object file mechanism. These chimpanzees are the first nonhuman animals to demonstrate extended memory for accumulated quantity.     

Amodal completion in visual search: preemption or context effects?

In a previous study, search for a notched-disk target abutting a square among complete-disk nontargets and squares was inefficient in 250-ms exposures, but relatively efficient in 100-ms exposures. This finding was interpreted as evidence that amodal completion proceeds through a mosaic and then a completion stage, with the latter preempting the former. We used the same target but changed its context: Nontargets were instead notched disks near squares. Task set was also different: Participants searched for a complete disk. Contrary to the prediction of the preemption model, search was efficient in the 100-ms condition and inefficient in the 250-ms condition. We propose that in both the present and the previous studies, the target was ambiguous, and task set and context affected how it was perceived. In both experiments, set effects were evident for 100-ms exposures; context effects were evident for 250-ms exposures.     

Why are average faces attractive? The effect of view and averageness on the attractiveness of female faces

Images of faces manipulated to make their shapes closer to the average are perceived as more attractive. The influences of symmetry and averageness are often confounded in studies based on full-face views of faces. Two experiments are reported that compared the effect of manipulating the averageness of female faces in profile and full-face views. Use of a profile view allows a face to be ”morphed“ toward an average shape without creating an image that becomes more symmetrical. Faces morphed toward the average were perceived as more attractive in both views, but the effect was significantly stronger for full-face views. Both full-face and profile views morphed away from the average shape were perceived as less attractive. It is concluded that the effect of averageness is independent of any effect of symmetry on the perceived attractiveness of female faces.     

Childhood maltreatment associated with adult personality disorders: findings from the Collaborative Longitudinal Personality Disorders Study

Adverse childhood experiences such as abuse and neglect are frequently implicated in the development of personality disorders (PDs); however, research on the childhood histories of most PD groups remains limited. In this multisite investigation, we assessed self-reported history of abuse and neglect experiences among 600 patients diagnosed with either a PD (borderline, schizotypal, avoidant, or obsessive-compulsive) or major depressive disorder without PD. Results indicate that rates of childhood maltreatment among individuals with PDs are generally high (73% reporting abuse; 82% reporting neglect). As expected, borderline PD was more consistently associated with childhood abuse and neglect than other PD diagnoses. However, even when controlling for the effect of borderline PD, other PD diagnoses were associated with specific types of maltreatment.     

Psychopathic traits in adolescent offenders: an evaluation of criminal history, clinical, and psychosocial correlates

Although a large body of research has established the relevance of psychopathy to adult offenders, its relevance to adolescent offenders is far less clear. The current study evaluated the clinical, psychosocial and criminal correlates of psychopathic traits in a sample of 226 male and female incarcerated adolescent offenders. According to an 18-item version of the Psychopathy Checklist-Youth Version (PCL-YV; Forth, Kosson, & Hare, 2003), only 9.4% exhibited a high level of psychopathic traits (PCL-YV>/=25). Consistent with past research, higher PCL-YV scores were positively associated with self-reported delinquency and aggressive behavior and were unrelated to emotional difficulties. Although higher PCL-YV scores were associated with the experience of physical abuse, the only psychosocial factor to predict PCL-YV scores was a history of non-parental living arrangements (e.g. foster care). In terms of criminality, a violent/versatile criminal history was positively associated with psychopathic traits. However, PCL-YV scores were unrelated to participants' official criminal records for total, non-violent, violent, and technical violation convictions. In conclusion, the data partially support the construct validity of psychopathy with adolescent offenders, but some inconsistencies with prior adult and adolescent psychopathy research were evident. These issues are discussed.     

Men's and Women's Perceptions of the Gender Typing of Management Subroles

The purpose of this study was to investigate the extent to which subroles inherent in managerial positions are gender-typed and whether men or women engage in relatively more gender typing of managerial roles. We obtained perceptions of 19 management subroles from 263 business students in the United States Results confirmed predictions that some subroles are viewed as more feminine in nature whereas other subroles are perceived as more masculine. Male respondents saw most subroles as more masculine in nature than did female respondents. Results are discussed in terms of implications for researchers studying management, as well as for managers in the workplace.     

Ethnic differences in battered women's formal help-seeking strategies: a focus on health, mental health, and spirituality

The primary goal of this study was to identify ethnic differences in battered women's use of health, mental health, and spiritual coping strategies, as well as differences in the perceived helpfulness of each strategy. The authors recruited a sample of 376 African American and Caucasian victims of interpersonal violence from various sites. In comparison with Caucasian women in the sample, African American women were significantly more likely to report using prayer as a coping strategy and significantly less likely to seek help from mental health counselors. The 2 groups did not significantly differ in terms of the extent to which they sought help from clergy or medical professionals. African American women found prayer to be more helpful than did Caucasian women.
