Case vignette: to share or not to share

For years, the notion that researchers should share data freely with fellow scientists has been discussed widely. Some argue that this is especially true when the data are generated in federally funded projects. A recent provision in the reauthorization bill for the National Institutes of Health (NIH) would ensconce this principle in law. NIH grantees would be required, on demand, to furnish their data to other researchers. According to the proposed legislation, research data would have to be preserved and made avilable for 3 years after the completion of a project, and for 5 years following publication of the results in a scientific journal. One objective, according to a congressional aide, would be to make it easier for scientists with dissenting views to obtain and reanalyze data collected with public funds. It would also facilitate publication of alternative analyses. Personal records and patent applications would be exempted, but other data from clinical, behavioral, or epidemiological research focused on the evaluation or efficacy of a drug, medical device, or treatment of any sort would be covered immediately. Is such mandatory sharing of data ethical and appropriate scholarship? Does it raise potential for abuse? Should colleagues be required to provide such access to data, whether or not federal support was used in its collection?     

Use of antianxiety drugs as countermeasures in the detection of guilty knowledge.

To evaluate whether antianxiety drugs enable guilty subjects to appear innocent on polygraph tests, we compared the effects of diazepam, meprobamate, and propranolol on the outcome of a guilty knowledge test (GKT). Seventy-five undergraduate students were evenly divided among one innocent and four guilty groups. Subjects in each of the guilty groups received either one of the drugs or a placebo prior to the administration of the GKT and after viewing a videotape that depicted a burglary as seen from the perspective of the burglar. The results showed that drug status had no influence on the outcome of the GKT. Innocent subjects who coincidentally obtained high scores on a recognition memory test covering details of the mock crime tended to obtain higher guilt scores on the GKT.     

Effects of transections to the vomeronasal nerves or to the main olfactory bulbs on the initiation and long-term retention of maternal behavior in primiparous rats.

While the onset of maternal behavior at parturition is mediated by hormones, the maintenance of maternal behavior during the first few postpartum weeks depends on experiences acquired while the dam interacts with pups (Rosenblatt, 1990). In fact, if female rats are permitted as little as 2 h or maternal experience within 36 h after Cesarean delivery, they exhibit heightened maternal behavior during maternal induction tests 10 days later; in contrast, dams separated from young at the time of Cesarean delivery and not permitted a maternal experience fail to respond maternally in tests 10 days later (Orpen & Fleming, 1987). In this study we investigated the role of chemosensory input through the vomeronasal and main olfactory systems in this maternal experience effect. Six groups of primiparous females were tested for maternal behavior to foster pups presented 9-10 days after Cesarean delivery: three groups were permitted to interact with pups for a 2-h period 36 h after Cesarean delivery; and three groups were separated from pups until testing and were given no maternal experience. Within each experience condition, one group sustained bilateral section of the vomeronasal nerves, one sustained bilateral coronal cuts through the midsection of the main olfactory bulbs, and one group sustained small medial olfactory bulb cuts. The results showed that animals sustaining vomeronasal or olfactory transections, regardless of experience condition, exhibited significantly reduced latencies to maternal behavior in maternal induction tests. However, these chemosensory disruptions did not prevent an additional facilitation of maternal behavior produced by a prior maternal experience.     

Interpersonal Assessment in Counseling and Psychotherapy

This article provides a review of some of the major instruments, methodologies, and strategies available to assess clients' interpersonal functioning. The focus is on instruments that provide characterizations of clients' and counselors' overt interpersonal behavior and covert reactions translated onto interpersonal circle models. A suggested interpersonal assessment battery is presented, and how the information obtained from this battery can be applied to assist in conceptualization and treatment efforts is described.     

Effects of counselor sex,student sex,and student attractiveness on counselors' judgments

Thirty-two male and thirty-two female high school counselors in a large metropolitan school district were provided with routine student profile data and asked to make predictions about the student's potential for post-high school education and to suggest occupations for the student to explore. All data reviewed by the counselors were identical except for a photograph of the student attached to the profile. Within counselor sex groups, counselors were randomly assigned to one of the following four photograph conditions: (a) attractive female; (b) unattractive female; (c) attractive male; and (d) unattractive male. Male subjects were found to discriminate on the basis of student sex when they suggested occupations for the student to explore. Predictions of post-high school education and the social status of suggested occupations were not found to be related to counselor sex, student sex, or student attractiveness.
