Simulation study of a decision-making model of squash competition, phase two: Testing the model through the use of computer simulation

This study aims at verifying the inner validity and logic of a squash competition decision-making model through the use of computer simulation. The model defines the cognitive-decisional strategy of the defending player (D) when selecting a motor reaction in response to his opponent's shot. Computer simulation of the model was carried out on a PDP-10 computer using a recent version of UCI-LISP. Protocol analysis data pertaining to the nature of the information D processes when awaiting the attacking player's shot were fed into the simulation program in order to examine the extent to which the model can reproduce decisions reached in various defensive contexts. Simulation results reveal that the proposed model can account for a substantial part of the variation in the speed and accuracy of D's motor reaction in real sport situations. Several factors like time pressure, expectancies, uncertainty, recency and familiarity of the relationship between signal and response appear to affect D's motor response via the cognitive-decisional strategy employed by the defending player. Particular discrepancies observed between simulation results and decisions reached by expert players in specific defensive situations nevertheless indicate that the decision rule utilized within the present model needs to be refined. In this regard, several issues are discussed and suggestions for further simulation studies are put forward in order to account more precisely for the various features characterizing the defensive player's motor reaction in real sporting context.     

Exploring cooperation and competition in the Centipede game through verbal protocol analysis

The Centipede game is an abstract model of reciprocal relationships in which two individuals alternate in helping each other at relatively small personal cost. Whereas mutual cooperation can benefit both individuals in the long run, a paradoxical but logically compelling backward induction argument suggests that cooperation is irrational. Empirical studies have reported reliable deviations from the non‐cooperative backward induction solution, but their exclusively quantitative methods allow only a limited range of predefined motives to be explored. Our study uses verbal (‘think aloud’) protocols and qualitative data analysis to identify motives for cooperation in the Centipede game. The results provide little evidence for sophisticated backward induction reasoning. Instead, a wide range of motives emerged, their relative saliences varying according to the stage of the game. Activity bias affected decisions mainly at the beginning of the game, whereas cooperative and altruistic social value orientations most frequently accounted for cooperation towards its natural end.     

High school students’ career decision-making process: A longitudinal study of one choice

This study investigated high school students’ process of choosing a study in higher education, using a longitudinal design. A sample of 535 adolescents participated at the beginning, middle, and end of Grade 12. Latent curve modeling revealed evidence for a mean developmental increase in the career decisional tasks of orientation, exploration, decisional status, and commitment. In general, the growth trajectories were in line with theoretical models in which orientation and broad exploration are important at the beginning of the career decision-making process whereas in-depth exploration and decisional status are considered important later on. Furthermore, the results showed substantial variability between adolescents in their initial levels of career decisional tasks and in the rate of change. Finally, growth in orientation related to growth in environmental and self-exploration, and growth in environmental exploration related to progress in commitment and decisional status.     

时间感知在跨期决策中的作用——时间决策模型的新探索

“时间”是跨期决策的“必需品”, 人们感知到的延迟时间决定跨期决策的结果。近年来, 研究者发现“时间长度感知”、“时间资源感知”和“时间框架感知”是时间感知作用于跨期决策的主要方式。时间感知的神经作用机制包含微观层面和宏观层面两种。“对数/指数时间折扣模型”、“感知时间基础模型”及“多模态漂移扩散模型”解释了时间感知的作用方式。然而, 现有理论模型还存在诸多局限, 主要包括“长短时距预测偏差”和“实际决策与预期决策偏差”两个方面。因此, 深入探讨时间感知影响跨期决策的基本方式, 分析现有理论模型的局限性并提出整合的机制框架具有十分重要的意义。未来研究亟需进一步整合时间感知的理论模型, 开展脑机制与应用方面的研究, 从深层揭露时间感知的作用本质, 帮助个人与社会更理性地决策。     

Anxiety enhances threat processing without competition among multiple inputs: a diffusion model analysis

Enhanced processing of threatening information is a well established phenomenon among high-anxious individuals. This effect is most reliably shown in situations where 2 or more items compete for processing resources, suggesting that input competition is a critical component of the effect. However, it could be that there are small effects in situations without input competition, but the dependent measures typically used are not sensitive enough to detect them. The present study analyzed data from a noncompetition task, single-string lexical decision, with the diffusion model, a decision process model that provides a more direct measure of performance differences than either response times or accuracy alone. The diffusion model analysis showed a consistent processing advantage for threatening words in high-anxious individuals, whereas traditional comparisons showed no significant differences. These results challenge the view that input competition is necessary for enhanced threat processing. Implications for theories of anxiety are discussed.     

A neurocognitive model of the ethical decision-making process: implications for study and practice

The field of business ethics is entrenched in a cognitive approach that portrays the ethical decision-making process as a completely deliberate and reasoned exercise. In light of growing concerns about the veracity of this approach, I build upon current knowledge of how the brain functions to present a neurocognitive model of ethical decision making. The model suggests that ethical decision making involves 2 interrelated yet functionally distinct cycles, a reflexive pattern matching cycle and a higher order conscious reasoning cycle, and thereby describes not only reasoned analysis, but also the intuitive and retrospective aspects of ethical decision making. The model sparks research in new areas, holds significant implications for the study of ethical decision making, and provides suggestions for improving ethical behavior in organizations.

Embryo genetic disorder analysis demonstration project: A model protocol

A demonstration project designed for couples at a minimum 25% risk for having a child with cystic fibrosis is being undertaken using embryo genetic disorder analysis within an organization proficient inin vitro fertilization techniques. Prior to offering the project to patients, issues were identified that needed to be addressed in order to improve the likelihood of success. We then developed a set of protocols that would enable us to introduce this new technology to our staff and to prospective patients in a consistent manner.     

The Web-Surf Task: A translational model of human decision-making

Animal models of decision-making are some of the most highly regarded psychological process models; however, there remains a disconnection between how these models are used for pre-clinical applications and the resulting treatment outcomes. This may be due to untested assumptions that different species recruit the same neural or psychological mechanisms. We propose a novel human foraging paradigm (Web-Surf Task) that we translated from a rat foraging paradigm (Restaurant Row) to evaluate cross-species decision-making similarities. We examined behavioral parallels in human and non-human animals using the respective tasks. We also compared two variants of the human task, one using videos and the other using photos as rewards, by correlating revealed and stated preferences. We demonstrate similarities in choice behaviors and decision reaction times in human and rat subjects. Findings also indicate that videos yielded more reliable and valid results. The joint use of the Web-Surf Task and Restaurant Row is therefore a promising approach for functional translational research, aiming to bridge pre-clinical and clinical lines of research using analogous tasks.     

Towards a competitive arousal model of decision-making: A study of auction fever in live and Internet auctions

In 1999, Chicago sponsored a public art exhibit of over 300 life-sized fiberglass cows that culminated in 140 Internet and live, in-person auctions. Collectively, the cows sold for almost seven times their initial estimates. These unexpectedly high final prices provided the impetus for a model of decision-making, “competitive arousal,” which focuses on how diverse factors such as rivalry, social facilitation, time pressure, and/or the uniqueness of being first can fuel arousal, which then impairs decision-making. In Study 1, live and Internet bidding and survey data from 21 auctions throughout North America tested the model’s predictions, as well as hypotheses derived from rational choice and escalation of commitment models. Analyses provided considerable support for the competitive arousal and escalation models, and no support for rational choice predictions. Study 2 was a laboratory experiment that investigated the similarities and differences between escalation and competitive arousal, finding again that both can result in overbidding. The discussion focuses on the implications of these findings and on the broader issue of competitive arousal and escalation and their impact on decision-making.     

From the decagonal phase to a related crystalline one

Abstract

We present here a rotation matrix in five-dimensional space which connects the decagonal phase to a tetragonal crystalline related phase through a one-dimensional quasicrystals range by means of a phason-phonon coupling. Phason and phonon fields are determined in a general way and, from this result, a simple linear approximation is given. Continuous evolution density-wave patterns are shown.     

Analysis of the decision-making process leading to appendectomy: a grounded theory study

The aim was to develop a theoretical understanding of the decision-making process leading to appendectomy. A qualitative interview study was performed in the grounded theory tradition using the constant comparative method to analyze data. The study setting was one county hospital and two local hospitals in Sweden, where 11 surgeons and 15 surgical nurses were interviewed. A model was developed which suggests that surgeons' decision making regarding appendectomy is formed by the interplay between their medical assessment of the patient's condition and a set of contextual characteristics. The latter consist of three interacting factors: (1) organizational conditions, (2) the professional actors' individual characteristics and interaction, and (3) the personal characteristics of the patient and his or her family or relatives. In case the outcome of medical assessment is ambiguous, the risk evaluation and final decision will be influenced by an interaction of the contextual characteristics. It was concluded that, compared to existing, rational models of decision making, the model presented identified potentially important contextual characteristics and an outline on when they come into play.     

Toward a model of self pathology underlying personality disorders: narratives, metacognition, interpersonal cycles and decision-making processes

If we want to explain the links between the various and heterogeneous elements--symptoms, dysfunctional forms of behavior and poor social functioning--making up personality disorders, we need model a self pathology that portrays dysfunctions, the links among them, and how their interactions maintain disorders over time. In our view, the most likely elements of self pathology are: a. problematic contents (thoughts and emotions)--experienced subjectively as states of mind and organized in the form of narratives; b. shortfalls in the ability, termed meta-cognition, to reflect on mental states, both of oneself and of others; c. pathogenic interpersonal schemas; and d. maladaptive decision-making processes. These elements get altered in the various personality disorders and interact to form typical pathological organizations. This article seeks to describe a model of self pathology in personality disorders and discuss its current scientific status based on a literature review that spans several disciplines. The model is illustrated with an example of how the pathogenic elements can interact to form personality disorder. Lastly, the limitations and advantages of the model are discussed.     

Making ethical choices: a comprehensive decision-making model for Canadian psychologists.

This paper proposes a theoretical augmentation of the seven-step decision-making model outlined in the Canadian Code of Ethics for Psychologists. We propose that teleological, deontological, and existential ethical perspectives should be taken into account in the decision-making process. We also consider the influence of individual, issue-specific, significant-other, situational, and external factors on ethical decision-making. This theoretical analysis demonstrates the richness and complexity of ethical decision-making.     

Religious factors in moral decision-making: Towards an integrated,socio-cultural,developmental, model

Abstract

For far too long, developmental approaches in the psychology of religion have paid insufficient attention to the richness and variety of social and cultural factors in human development and their relationship to religious belief, practice, belonging, identity, and world views, and often, related framing of spiritual questions, concerns, and disciplines. If scholars in the psychology of human development and psychology of religion have offered critical appraisals of the shortcomings of the neo-Piagetian, cognitive-developmental models that have dominated the scientific literature, and offered promising contributions and needed correctives to the omissions of cognitive-developmental approaches, the field is still in need of an integrated, socio-cultural developmental approach to human development and religious functioning. In this article we propose one way of moving toward a more integrated approach in these fields, with special attention to the advantages of such an effort in the study of religious elements in moral decision-making and moral development.     

The end phase of analysis: indicators, functions, and tasks of termination

This paper considers the end phase of analysis. Beginning with a brief review of the literature on termination, specifically the indicators for initiating the termination process, we identify the structural attainments necessary for the patient to successfully complete the analysis and to maintain smooth post-analytic functioning. We stress in this regard the significance of self-analytic functions and the relative immutability of the transference neurosis. These points are illustrated with clinical examples. Our paper concludes with a discussion of the tasks and contributions of the analyst during the termination process. We make special reference to countertransference vulnerability resulting from the analyst's own termination experiences.
