Disclosure of Genetic Research Results to Members of a Founder Population

There is currently extensive discussion and debate in the literature on how, when, and to whom genetic research results should be returned (see Genetics in Medicine, April 2012 issue). Here, we describe our experience in disclosing genetic information on Mendelian disorders discovered during the course of our research in the Hutterites. We first assessed attitudes toward the disclosure of carrier results, which revealed that many individuals wanted carrier information and that many intended to use the information in family planning. Based on this information, we developed a pilot study to test and disclose cystic fibrosis (CF) carrier status. Next, a larger scale project was developed in order to disclose genetic research results for 14 diseases to those interested in receiving the information. We developed brochures, offered a live interactive educational program, conducted a consent process, and disclosed results in letters mailed to the consented individuals. Overall, ~80 % of individuals who participated in the educational program signed consent forms for the release of their results for 14 diseases. We describe our experience with returning individual genetic research results to participants in a population-based research study.     

A Qualitative Inquiry of the Financial Concerns of Couples Opting to Use Preimplantation Genetic Diagnosis to Prevent the Transmission of Known Genetic Disorders

Preimplantation genetic diagnosis (PGD) is an innovative prenatal testing option because the determination of whether a genetic disorder or chromosomal abnormality is evident occurs prior to pregnancy. However, PGD is not covered financially under the majority of private and public health insurance institutions in the United States, leaving couples to decide whether PGD is financially feasible. The aim of this qualitative study was to understand the role of finances in the decision-making process among couples who were actively considering PGD. In-depth, semi-structured interviews were completed with 18 genetic high-risk couples (36 individual partners). Grounded theory guided the analysis, whereby three themes emerged: 1) Cost is salient, 2) Emotions surrounding affordability, and 3) Financial burden and sacrifice. Ultimately, couples determined that the opportunity to avoid passing on a genetic disorder to a future child was paramount to the cost of PGD, but expressed financial concerns and recognized financial access as a major barrier to PGD utilization.     

Variations in the magnitude of attentional capture: Testing a two-process model

Although large variations in the magnitude of attentional capture have been evidenced across a wide range of studies and paradigms (see Burnham, 2007, for a review), the nature of these variations is unclear. In the present study, we used a modified spatial cuing task to address two related issues. In the first experiment, we explored the hypothesis that the magnitude of attentional capture varies systematically as a function of cue-target similarity. Targets of a particular color were preceded by uninformative peripheral cues carrying varying percentages of the target color. As was predicted, the magnitude of attentional capture varied directly with the similarity between cue and target. In the second experiment, we explored whether these similarity effects reflect a mixture of trials on which attention is fully captured and trials on which attention is not captured at all (i.e., a two-process model). A mixture analysis conducted on obtained reaction time distributions proved inconsistent with a two-process model.     

How do African grey parrots (Psittacus erithacus) perform on a delay of gratification task?

Humans and other animals often find it difficult to choose a delayed reward over an immediate one, even when the delay leads to increased pay-offs. Using a visible incremental reward procedure, we tested the ability of three grey parrots to maintain delay of gratification for an increasingly valuable food pay-off. Up to five sunflower seeds were placed within the parrot’s reach, one at a time, at a rate of one seed per second. When the parrot took a seed the trial was ended and the birds consumed the accumulated seeds. Parrots were first tested in daily sessions of ten trials and then with single daily trials. For multiple trial sessions, all three parrots showed some limited improvement across 30 sessions. For single trial sessions, only one parrot showed any increase in seed acquisition across trials. This parrot was also able to consistently obtain two or more seeds per trial (across both multiple and single trial conditions) but was unable to able to wait 5 s to obtain the maximum number of seeds. This parrot was also tested on a slower rate of seed presentation, and this significantly reduced her mean seed acquisition in both multiple and single trial conditions, suggesting that both value of reward available and delay duration impact upon self-control. Further manipulation of both the visibility and proximity of seeds during delay maintenance had little impact upon tolerance of delays for both parrots tested in this condition. This task demanded not just a choice of delayed reward but the maintenance of delayed gratification and was clearly difficult for the parrots to learn; additional training or alternative paradigms are required to better understand the capacity for self-control in this and other species.     

Violent Attitudes and Deferred Academic Aspirations: Deleterious Effects of Exposure to Rap Music

The purpose of this study was to assess the effects of exposure to rap music on the attitudes and perceptions of young African-American males. Subjects u were exposed to violent rap music videos, nonviolent rap music videos, or no music videos (controls). They read two vignettes, involving: (a) a violent act perpetrated against a man and a woman, and (b) a young man who chose to engage in academic pursuits to achieve success, whereas his friend, who was unemployed, "mysteriously" obtained extravagant items (i.e., a nice car, nice clothes). Results indicated, first, that when compared to subjects in the nonviolent exposure and control conditions, subjects in the violent exposure conditions expressed greater acceptance of the use of violence. Second, when compared to subjects in the control condition, subjects in the violent condition 'reported a higher probability that they would engage in violence. Third, when compared to the controls, subjects in the violent exposure condition expressed greater acceptance of the use of violence toward the woman. Finally, when compared to the controls, subjects in the rap video exposure conditions were more' likely to say that they wanted to be like the materialistic young man and were less confident that the other young man would achieve his educational goals. Possible basis for and implications of these findings are discussed.     

A Positive and Proactive Approach to the Ethics of the First Interview

Some may view the initial interview as a mechanistic procedure complete with a list of tasks to accomplish. The primary purpose of this article is to deconstruct this perspective and encourage psychotherapists to explore the initial interview through an ethical acculturation lens. Using a case scenario, we demonstrate the need for purposeful reflection to better understand important judgments and choices psychotherapists make while conducting initial interviews. Employing a proactive approach to ethics using a “wide-angle” lens, we organize the discussion around personal, professional, and global themes. We offer practical tips to facilitate ethical excellence as psychotherapists engage in their first client contacts.     

Motor Learning as a Function of KR Schedule and Characteristics of Task-Intrinsic Feedback

Forty participants (age range = 18–35 years) practiced 1 of 2 versions of an aiming task (with or without spring resistance). Knowledge of results (KR) was provided to them either immediately or after a delay of 2 trials. Immediate KR led to significantly more accurate performance during the 80 trials in acquisition but significantly less accurate performance on a 40-trial retention test given 24 hr after practice. In addition, the spring version of the task was performed significantly less accurately than the no-spring version on the 24-hr retention test. Most important, a significant interaction on the 24-hr retention test revealed that performance of the no-spring version of the task, when KR had been given after a 2-trial delay, was significantly more accurate than performance of the other 3 combinations of task version and KR schedule. The results suggest that KR dependency in motor skill learning is related to familiarity with task-intrinsic feedback in addition to the schedule on which KR is presented.
