Facing the high degree of uncertainty of the environment, we have evolved two kinds of decision-making styles: context-dependent and context-independent decision. However, the underlying neural basis of these two kinds of decision styles was mostly unknown. Here, the cognitive bias task was applied to split participants into the context-independent decision-maker and context-dependent decision-maker based on the cognitive bias task scores. Then, we used voxel-based morphometry to directly investigate its underlying differences in gray matter volume. We found that the gray matter volume of the prefrontal cortex and parietal regions, such as inferior parietal lobule, was larger in context-dependent decision-makers than that of the context-independent decision-maker.

The Relationship

The relationship between cancer patients’ desire for information and their preference for participation in decision making has been examined. Approximately 77% of the 52 patients reported that they had participated in decision making to the extent that they wished, while most of the remaining 23% would have preferred an opportunity to have greater input. Although many of the patients actively sought information, a majority preferred the physician to assume the role of the primary decision maker. Ethically, the disclosure of information has been assumed to be necessary for autonomous decision making. Nevertheless, the results of this study indicate that patients may actively seek information to satisfy an as yet unidentified aspect of psychological autonomy that does not necessarily include participation in decision making.

The paper presents the ideology of a qualitative approach to decision making ‐ verbal decision analysis. The authors have analyzed existing quantitative approaches and pointed out their main disadvantages. They formulated the requirements for decision‐making methods taking into account these disadvantages: psychological correctness of a dialog with decision maker (DM), strict mathematical proof of the methods and checking of DM information for consistency. The authors present the results of research on psychological correctness of operations of preference elicitation from DM. Several existing verbal decision analysis methods are briefly mentioned.

At Home

In this research paper, we look at decision-making by women in India from a contextual perspective. This study looks at decision making by women as based on four possible contexts that may arise, and where decisions are called for. These contexts are qualified based on two broad parameters, namely the level of involvement (dictated by the stakes at play) and the predisposition displayed. Involvement is qualified as high or low (on a continuum), whilst predisposition is stated as either cognitive or affective. The results of the research study reveal a difficult act of balancing that women have to do in terms of decision making at home. They need to get their decisions, whether it is about their career, or their choice of mate, about home, marriage, children ratified by their husbands or parents, women also try to ensure that such decisions do not reflect poorly on their homes. This calls for them to balance between options and often sacrifice their self-interest in the interest of their “home.”

Practical Implications

Where a person is unable to make medical decisions for themselves, law and practice allows others to make decisions on their behalf. This is common at the end of a person’s life where decision-making capacity is often lost. A further, and separate, decision that is often considered at the time of death (and often preceding death) is whether the person wanted to act as an organ or tissue donor. However, in some jurisdictions, the lawful decision-maker for the donation decision (the ‘donation decision-maker’) is different from the person who was granted decision-making authority for medical decisions during the person’s life. To date, little attention has been given in the literature to the ethical concerns and practical problems that arise where this shift in legal authority occurs. Such a change in decision-making authority is particularly problematic where premortem measures are suggested to maximise the chances of a successful organ donation. This paper examines this shift in decision-making authority and discusses the legal, ethical and practical implications of such frameworks.

Optimal Information

When faced with a decision between several options, people rarely fully consider every alternative. Instead, we direct our attention to the most promising candidates, focusing our limited cognitive resources on evaluating the options that we are most likely to choose. A growing body of empirical work has shown that attention plays an important role in human decision making, but it is still unclear how people choose with option to attend to at each moment in the decision making process. In this paper, we present an analysis of how a rational decision maker should allocate her attention. We cast attention allocation in decision making as a sequential sampling problem, in which the decision maker iteratively selects from which distribution to sample in order to update her beliefs about the values of the available alternatives. By approximating the optimal solution to this problem, we derive a model in which both the selection and integration of evidence are rational. This model predicts choices and reaction times, as well as sequences of visual fixations. Applying the model to a ternary-choice dataset, we find that its predictions align well with human data.

The paper presents the decision support under risk by the risk averse decision maker. Decision making under risk occurs when the result of the decision is not unequivocal and depends on the state of the environment. The decision making process is modeled with the use of multi-criteria optimization. The decision is made by solving the problem with the control parameters that determine the decision maker's aspirations and the evaluation of the solutions received. The decision maker asks the parameter for which the solution is determined. Then, evaluate the solution received accepting or rejecting it. In the second case, the decision maker gives a new parameter value and the problem is solved again for the new parameter. The work includes an simple discrete problem of decision support under risk

Abstract The purposes of this study were to describe who should be involved in the vascular access device (VAD) decision-making process, according to patients and caregivers, and to describe if there were differences associated with persons involved in the selection of VADs according to race and gender. Convenience sample included 32 oncology out-patients and 10 caregivers from the southern United States. There were differences by race and sex in decision-making priorities of patients with vascular access devices indwelling; however, these were not statistically significant. Patients, physicians, and oncology nurses were viewed by both patients and caregivers as significant to the decision-making process. In contrast, caregivers were ranked as the least significant by both patients and caregivers. Females chose the physician as the primary decision-maker while males chose the patient as the primary decision-maker.

Selection of a most appropriate material is a very important task in design process of every product. There is a need for simple, systematic, and logical methods or mathematical tools to guide decision makers in considering a number of selection attributes and their interrelations and in making right decisions. This paper proposes a novel multiple attribute decision making (MADM) method for solving the material selection problem. The method considers the objective weights of importance of the attributes as well as the subjective preferences of the decision maker to decide the integrated weights of importance of the attributes. Furthermore, the method uses fuzzy logic to convert the qualitative attributes into the quantitative attributes. Two examples are presented to illustrate the potential of the proposed method.
