Self-Other Discrepancies in Waiting Time Decisions

Both anecdotal evidence and recently reported research suggest that people are risk-averse when faced with waiting time decisions. Four studies investigate whether there is a self-other discrepancy in how people make waiting time decisions themselves and how they predict others will make similar decisions. People are found to believe that others have valuations of time similar to their own. However, when faced with alternatives that involve risk in the duration of the wait, the results point to a self-other discrepancy, in that people report greater risk-aversion themselves than they think others would. Further, when faced with waiting time gains, people are themselves more risk-averse than they think others would be. Conversely, when faced with waiting time losses, people are themselves more risk-seeking than they think others would be. Overall, the results are consistent with the recently proposed risk-as-feelings hypothesis.     

Why Young Men Drive Dangerously: Implications for Injury Prevention

Why is risk consistently underestimated, and why do young men in particular take exceptionally high risks and think of themselves as invulnerable? Two explanatory paths are proposed. The first is that risk taking in young males has been shaped by evolutionary forces to provide a fitness value. The second pathway is through myth and the other narrative forms that affirm the ego's immortality and invulnerability. Because of its evolutionary base, risk taking is emotionally driven: Emotions are preverbal and irrational, which means that persuasive prevention cannot be more than weakly successful. Three prevention challenges emerge from this analysis: to determine what it is that young drivers fear, to attach affectively experienced fears to defined driving behaviors, and to devise injury-prevention programs that acknowledge that young males' risk taking is not "stupid," but driven by adaptive needs that are as significant to today's young adults as they were to our distant ancestors.

Approaching Complex Cases With a Crisis Intervention Model and Teamwork

Patients referred for genetic counseling may be in a state of crisis, feeling as though they are incapable of making decisions about the management of their pregnancy, genetic testing options and/or life planning issues. The role of the genetic counselor is to assist a patient through this crisis state by increasing the patient's understanding and by helping to facilitate decision making and adjustment to those decisions. In this paper we present a clinical genetic counseling case that was complicated by numerous medical and psychosocial issues. The wide scope of this case required the involvement of both a prenatal and a medical genetic counselor. Working as a team we utilized a crisis intervention model. Our counseling focused on identifying and isolating the issues, providing factual information, setting a time frame for decisions to be made, and encouraging social support and emotion-focused coping strategies.     

Guidelines for Writing Letters to Patients

Patient letters provide a permanent record of the genetic counseling that was provided and are unique in medical care; rarely do other health care providers send summaries written specifically to their patients and families. We surveyed genetic counseling training program directors and found that while the acquisition of patient letter-writing skills was considered important, there were no specific guidelines made available to students. To develop letter-writing guidelines, we evaluated patient letters, reviewed references on professional correspondence, surveyed the medical literature, and worked with a writing consultant. The guidelines we subsequently developed and present here include a format for writing patient letters, suggestions on presenting medical information in understandable terms, and wording considerations. These patient letter-writing guidelines are intended to serve as a guide for teaching students this important skill and as a resource for practicing health care professionals.     

A study of emotion and reason in products and services

This study investigates the relationship between emotion, reason and perceived risk. Evidence is presented using an aggregative data set of 146 products and services which were randomly selected from the SIC (Standard Industrial Classification Codes) manual. It is demonstrated that emotional factors account for a significant and substantial portion of the variance in perceived risk even after the effect of rational factors (perceived differences between alternatives) has been taken into account. It is suggested that emotion be explicitly modelled in future conceptualisations of perceived risk. Copyright © 2002 Henry Stewart Publications.     

Developing Standard Recommendations (Guidelines) for Genetic Counseling Practice: A Process of the National Society of Genetic Counselors

The National Society of Genetic Counselors (NSGC) supports the development of practice recommendations (guidelines) in the field of genetic counseling. This paper reviews the basic components of NSGC genetic counseling practice recommendations as well as the process for formal adoption of such documents, as approved by the Board of Directors of the NSGC.     

The Genetic Counseling Workplace—An Australasian Perspective. A National Study of Workplace Issues for Genetic Counselors and Associate Genetic Counselors

Genetic counseling in Australasia (Australia and New Zealand) has been recognized as a profession since the 1980s and has steadily expanded over the past 20 years. The demography of major cities with metropolitan sprawl and sparsely populated rural areas has led to the establishment of 3 types of genetics units: main units in cities, metropolitan outreach, and rural outreach units. A questionnaire was developed to obtain information about the needs, resources, and day-to-day operation of the genetic counselors. The questionnaire addressed the areas of resource availability, professional development, responsibility of genetic counselors in the clinical setting, and their involvement in promotion of the service and public education. Differences observed between the 3 settings in all of these areas included large clinical loads for metropolitan outreach counselors, varying responsibilities in the clinical setting, and a lack of support and resources for rural outreach counselors. Australasian Genetic counselors were found to have a significant interest in developing mechanisms for supervision and were keenly interested in maintaining credentials and professional role development. The results of this study allows genetic counselors themselves to have a better understanding of the roles of their colleagues in the different units; they can also be used by service providers in establishing and supporting genetic counselors, and identifying inequalities and deficiencies in the different practice areas.     

Risk perception and risky choice: Situational, informational and dispositional effects

We investigated how situational (gain–loss), informational (opportunity–threat framing) and dispositional (achievement motive and avoidance motive) variables affected opportunity–threat perception and risky choice in managerial decision-making contexts. In Study 1, the risk preference of the participants showed a reflection effect due to situational differences (gain or loss) and a partial framing effect caused by presenting the same choice information in terms of either opportunities or threats. However, both effects were in the opposite direction of predictions from prospect theory. Gains and positive framing enhanced risk-seeking preference whereas losses and negative framing augmented risk-averse preference. Risk-seeking choices were mediated by opportunity perception whereas risk-averse choices were mediated by threat perception. In Study 2, the participants high in achievement motive perceived greater opportunities in a negative situation, and the participants high in avoidance motive perceived greater threats in a positive situation, suggesting that ambition (achievement motive) operates more significantly in the face of adversities whereas cautiousness (avoidance motive) functions more significantly in prosperity.     

Habituation in high‐risk infants: reliability and patterns of responding

We examined both the reliability of infant‐controlled habituation and patterns of responding in a group of high‐risk infants (mean age 16 mos). Good test–retest reliability was found for mean, total, and baseline looking time for one of the stimuli. Classification of infants' pattern of performance yielded two groups: linear (57%) and non‐linear (29%) responders; 14% of cases could not be classified because of cross‐session inconsistencies in performance. Linear responders had shorter total looking times, fewer trials to criterion, and showed more habituation than non‐linear responders, thus validating the linear/non‐linear distinction. Our findings indicate that the infant‐controlled habituation task can be used reliably with infants who are at high risk for developmental disorders. Indeed, we provide evidence that this task is not only reliable, but may also provide meaningful distinctions between infants within the high‐risk population. Discussion focuses on the role of attention in distinguishing between short (linear) and long (non‐linear) lookers. Copyright © 2003 John Wiley & Sons, Ltd.
