Personality components of decision making

Summary Relationships between proneness to behavioral stereotypy (Ster) measured in a problem-solving task (electromaze) and decision-making behavior (under conditions of risk and certainty, chance and skill) were investigated using 64 subjects. Subjects more stereotyped in the electromaze (Ster ⁺) tended to also be more stereotyped in their decision-making behavior. Ster was not related to extraversion, neuroticism, rigidity or overall electromaze performance, but Ster ^– more often required an excessive number of trials for task solution. The decision making of males tended to be more stereotyped. The results were discussed in terms of the construct validity and theoretical interpretation of Ster.

Zusammenfassung Es wurden Beziehungen zwischen der Neigung zur Verhaltensstereotypie (Ster), die bei einer Problemlösungsaufgabe gemessen wurde, und dem Entscheidungsverhalten (mit und ohne Risiko, wobei der Erfolg sowohl durch den Zufall wie auch durch das Können der Vp bestimmt wurde) untersucht. Vpn, die sich im Electromaze stereotyp verhielten (Ster ⁺), verhielten sich auch bei ihren Entscheidungen stereotyp. Es wurden keine Beziehungen zwischen Ster und den Variablen Extraversion, Neurotizismus, Rigidität und Gesamtleistung im Electromaze gefunden, jedoch benötigten Ster ^– häufiger eine extrem lange Serie von Versuchen zur Aufgabenlösung. Die männliche Vpn neigten stärker dazu, in Entscheidungssituationen stereotyp zu reagieren. Die Ergebnisse wurden vom Standpunkt der Konstruktvalidität und der theoretischen Grundlage der Ster aus diskutiert.

     

Automatic and controlled components of judgment and decision making

The categorization of inductive reasoning into largely automatic processes (heuristic reasoning) and controlled analytical processes (rule-based reasoning) put forward by dual-process approaches of judgment under uncertainty (e.g., K. E. Stanovich & R. F. West, 2000) has been primarily a matter of assumption with a scarcity of direct empirical findings supporting it. The present authors use the process dissociation procedure (L. L. Jacoby, 1991) to provide convergent evidence validating a dual-process perspective to judgment under uncertainty based on the independent contributions of heuristic and rule-based reasoning. Process dissociations based on experimental manipulation of variables were derived from the most relevant theoretical properties typically used to contrast the two forms of reasoning. These include processing goals (Experiment 1), cognitive resources (Experiment 2), priming (Experiment 3), and formal training (Experiment 4); the results consistently support the author's perspective. They conclude that judgment under uncertainty is neither an automatic nor a controlled process but that it reflects both processes, with each making independent contributions.     

An outcomes model of medical decision making

In the traditional fix-it model of medical decision making, the identified problem is typically characterized by a diagnosis that indicates a deviation from normalcy. When a medical problem is multifaceted and the available interventions are only partially effective, a broader vision of the health care endeavor is needed. What matters to the patient, and what should matter to the practitioner, is the patient's future possibilities. More specifically, what is important is the character of the alternative futures that the patient could have and choosing among them so as to achieve the best future possible, with the ranking of outcomes determined by the patient's preferences. This paper describes the fix-it model, presents and defends the outcomes-based model, and demonstrates that the latter is useful in developing normative conceptions of informed consent and decision making and in establishing a basis for societal involvement in the decision making process. Finally, several shortcomings of the model will be acknowledged.     

Effort and demand logic in medical decision making

Medical decisions, including diagnosis, prognosis, and disease classification, must often be made on the basis of incomplete or unsatisfactory information. Data which are essential to the care of one patient may be unobtainable for technical or ethical reasons in another patient. For this reason the principles of controlled experimentation may be impossible to satisfy in human studies. In this paper, some formal aspects of medical decision making are discussed. Special operators for the intuitive concepts of ‘certainty’, ‘demand’, and ‘effort’, akin to the operators of modal logic, are used to accommodate the technical and ethical limitations on human studies. Theorems are stated and proved which show how this system handles incomplete information. The embryogenesis of the human heart is presented as a sample problem in classification.     

Biasing decision making by means of retrieval practice

Decision making requires the recruitment of several cognitive processes. So far, however, few studies have dealt with the role of inhibitory control in this domain. In this study, we aim to examine this issue in a memory-based decision task by using an adaptation of the retrieval practice paradigm (Anderson, Bjork, & Bjork, 1994 Anderson, M. C., Bjork, R. A. and Bjork, E. L. 1994. Remembering can cause forgetting: Retrieval dynamics in long-term memory. Journal of Experimental Psychology: Learning, Memory, and Cognition, 20: 1063–1087. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The retrieval-induced forgetting found through this task is normally explained in terms of inhibition. Specifically, we analyse how retrieval practice may affect what alternatives are selected as well as the choice probability and attribute recall. Our data show a relation between the recall impairment of the attributes due to retrieval practice and biased decisions.     

The place of prudence in medical decision making

In the world of practical affairs in general, no less than in the matter of medicalethical decision making, there is place for the possession of the classical virtue of prudence. Most persons involved in making such decisions are interested exclusively in solving a case, and ignore the importance of growing in virtue and character at the same time while having their decision reflect prudential reasoning. A study of the virtue of prudence shows that it is a much misunderstood virtue, and requires deeper penetration into its meaning to grasp its place in humanizing medical decisions.     

The current environment for medical decision making: Alternative efficiency concepts and decision motivation

Health services delivery is rapidly changing in the U.S. and along with it the incentives and motives for making decisions about the use of services. This paper discusses the economic criteria for making good decisions from both individual and social perspectives. The position is taken that individual criteria for decision-making efficiency in health services is quite different from social efficiency criteria but the two perspectives can be viewed as complementary. These criteria are used to examine current developments in health services, including aggressively competitive managed care. The analysis concludes that current directions may be in conflict with both social and individual efficiency. Alternative public policies are required to alter motives and incentives such that decisions better meet the complementary efficiency criteria.Originally prepared for presentation at the Annual Meeting of the American Association for the Advancement of Science, Atlanta, Georgia, February 17, 1995, as part of the symposium Cognitive Interpersonal, and Societal Influences on Medical Decision Making (A. M. Isen and B. S. Moore, Chairs).     

Brief body-scan meditation practice improves somatosensory perceptual decision making

We have previously found that attention to internal somatic sensations (interoceptive attention) during a heart beat perception task increases the misperception of external touch on a somatic signal detection task (SSDT), during which healthy participants erroneously report feeling near-threshold vibrations presented to their fingertip in the absence of a stimulus. However, it has been suggested that mindful interoceptive attention should result in more accurate somatic perception, due to its non-evaluative and controlled nature. To investigate this possibility, 62 participants completed the SSDT before and after a period of brief body-scan mindfulness meditation training, or a control intervention (listening to a recorded story). The meditation intervention reduced tactile misperception and increased sensitivity during the SSDT. This finding suggests that the perceptual effects of interoceptive attention depend on its particular nature, and raises the possibility that body-scan meditation could reduce the misperception of physical symptoms in individuals with medically unexplained symptoms.     

Influence of consultation on ethical decision making: an analogue study

Participants (62 students from 6 doctoral programs in professional psychology) were given 3 ethical dilemmas, asked to generate their own solutions, and asked to make judgments about a number of provided alternatives. Students were asked either to make decisions after seeking consultation or to make decisions independently of consultation. There were few significant between-group differences along a number of dimensions including participants' ratings of acceptability of provided alternatives and levels of certainty, justification, and satisfaction with personally generated solutions. For one of the vignettes, individuals using consultation, when compared with the control group, were significantly more likely to prefer their own solution to that of provided alternatives. The study was viewed as a needed first step in investigating a cherished assumption in clinical practice.     

Toward a hermeneutic model of ethical decision making in clinical practice

Documented ethical violations and empirical research have demonstrated that, despite professional standards and formal training in ethical principles, some psychotherapists engage in unethical behaviors that compromise the welfare of clients. It appears that competing values and interests that emerge in the therapeutic endeavor can interfere with therapists' considerations of ethical standards and their willingness to act ethically. Expanding current models of ethical decision making, this article offers a hermeneutic model that recognizes that in addition to moral reasoning, the context of the therapeutic relationship and the therapist's subjective responses are fundamental considerations in the interpretation and application of ethical interventions. Implications for understanding and training of ethics in psychotherapy in this broader context are explored.     

共情关怀对公平决策的影响——来自ERP的证据

本研究运用事件相关电位技术(event-related potential, ERP)和最后通牒博弈范式(ultimatum game, UG)考察了共情关怀对公平决策的影响。实验采用2 (状态共情关怀: 有共情关怀vs.无共情关怀) × 3 (分配公平性: 公平vs.劣势不公平vs.优势不公平)被试内设计, 共37名被试参与实验, 被试作为响应者选择是否接受提议者的分配提议。行为结果显示劣势不公平条件下, 有共情情境的接受率高于无共情情境; 优势不公平条件下呈现相反的结果。ERP结果显示: 对于他人提出的优势不公平提议, 无共情情境较有共情情境下诱发了更负的前部N1 (anterior N1, AN1), 有共情情境比无共情情境下诱发了更大的P2波幅; 有共情情境下, 他人提出的劣势不公平提议较优势不公平和公平提议诱发了更负的内侧额叶负波(medial frontal negativity, MFN); P3在公平条件下的波幅较劣势不公平条件下更大, 并未受到共情关怀的调节。这些结果表明共情关怀不仅调节了公平决策行为, 还调节了公平加工的早期注意和动机及之后的认知和情绪加工, 但由P3表征的高级认知过程仅受到公平性的调节而不受共情水平的影响。     

Numeracy and decision making

A series of four studies explored how the ability to comprehend and transform probability numbers relates to performance on judgment and decision tasks. On the surface, the tasks in the four studies appear to be widely different; at a conceptual level, however, they all involve processing numbers and the potential to show an influence of affect. Findings were consistent with highly numerate individuals being more likely to retrieve and use appropriate numerical principles, thus making themselves less susceptible to framing effects, compared with less numerate individuals. In addition, the highly numerate tended to draw different (generally stronger or more precise) affective meaning from numbers and numerical comparisons, and their affective responses were more precise. Although generally helpful, this tendency may sometimes lead to worse decisions. The less numerate were influenced more by competing, irrelevant affective considerations. Analyses showed that the effect of numeracy was not due to general intelligence. Numerical ability appears to matter to judgments and decisions in important ways.     

Subjective decision making in medical school admissions: Potentials for discrimination

Medical schools place considerable emphasis on admissions interviews in the selection of students. Interviews, with unwritten performance criteria and subjective evaluation, contain the potential for unconscious discrimination against certain groups of applicants. This study investigates the contribution of interview scores to the total evaluation of male and female applicants for admission to one medical school in the United States. Findings reveal that interveiw scores are counted more heavily for females than males in arriving at a final ranking for admission. Further, females were rated lower in general than males on interview evaluations. While the magnitude of the associations is small, the combined effect points to a potential for discrimination, however unintended, against women applicants in the present case study.The authors appreciate the valuable criticisms of and comments on an earlier draft from Drs. Sidney Fleming, Dorothy Brinsfiled, Glenn Clark, Maurice Jurkiewicz, and Michael Kutner, some of whom may still take exception to parts of this article.
