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.     

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.     

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.     

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.

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.     

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.     

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.     

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.     

Simulation and virtual reality in medical education and therapy: a protocol.

Continuing medical education has historically been provided primarily by didactic lectures, though adult learners prefer experiential or self-directed learning. Young physicians have extensive experience with computer-based or "video" games, priming them for medical education--and treating their patients--via new technologies. We report our use of standardized patients (SPs) to educate physicians on the diagnosis and treatment of biological and chemical warfare agent exposure. We trained professional actors to serve as SPs representing exposure to biological agents such as anthrax and smallpox. We rotated workshop participants through teaching stations to interview, examine, diagnose and treat SPs. We also trained SPs to simulate a chemical mass casualty (MASCAL) incident. Workshop participants worked together to treat MASCAL victims, followed by discussion of key teaching points. More recently, we developed computer-based simulation (CBS) modules of patients exposed to biological agents. We compare the strengths and weaknesses of CBS vs. live SPs. Finally, we detail plans for a randomized controlled trial to assess the efficacy of virtual reality (VR) exposure therapy compared to pharmacotherapy for post-traumatic stress disorder (PTSD). PTSD is associated with significant disability and healthcare costs, which may be ameliorated by the identification of more effective therapy.     

Converting a Freudian analysis into a Jungian one: obsession,addiction, and an answer from Job

In his analyses of obsessional patients, Sigmund Freud suggested that they suffered from intrusive cognitions and compulsive activities. Early psychoanalysts delineated the phenomenology of obsessionality, but did not differentiate what is currently termed obsessive‐compulsive disorder from obsessional personality. However, it was widely recognized that the success of psychoanalysis with obsessional patients was limited due to rigid characterological defences and transference resistances. The present paper examines the case of a middle‐aged obsessional academic who had been treated for nearly twenty years in a ‘classical' Freudian psychoanalysis prior to entering Jungian analysis. It examines how persistent focus on Oedipal conflicts undesirably reinforced the transference resistance in this obsessional man, and suggests that focusing instead on diminishing the harshness of the super‐ego via the therapeutic alliance, and fostering faith in the salutary aspects of unconscious processing has led to salutary results in this case. The biblical book of Job is adopted as ancient instruction in how to address the scrupulosity and addictive mental structuring of obsessionality in analysis.     

Aging, practice, and perceptual tasks: a diffusion model analysis

Practice effects were examined in a masked letter discrimination task and a masked brightness discrimination task for college-age and 60- to 75-year-old subjects. The diffusion model (Ratcliff, 1978) was fit to the response time and accuracy data and used to extract estimates of components of processing from the data. Relative to young subjects, the older subjects began the experiments with slower and less accurate performance; however, across sessions their accuracy improved because the quality of the information on which their decisions were based improved, and this, along with reduced decision criteria, led to shorter response times. For the brightness, but not the letter, discrimination task, the older subjects' performance matched that of the younger group by the end of 4 sessions, except that their nondecision components of processing were slightly slower. These analyses illustrate how a well-specified model can provide a unified view of multiple aspects of data that are often interpreted separately.     

Mourning analysis: the post-termination phase

One hundred twenty-one analytic candidates who had completed training analysis responded to a survey about their post-termination experience. Seventy-six percent of respondents experienced a mourning process that lasted on average between six months and a year, while 24 per cent experienced no discernible sense of painful loss. Twenty candidates were interviewed to obtain a deeper understanding of the mourning process that follows analysis. During the post-termination phase, the analysand's self-analytic capacity is tested in the struggle to contain and understand feelings about the loss of the analyst, as well as transference reactions triggered by that loss. After a "good-enough analysis," the analysand internalizes not only the analyst's functions and attitudes toward him or her, but also a sustaining, positive internal image of the analyst. Four cases illustrate unexpected difficulties that may emerge during the post-termination phase when the loss of the analyst is experienced as a repetition of earlier, traumatic losses or as a rupture of an unanalyzed, selfobject transference.     

Different athletes cope differently during a sport competition: a cluster analysis of coping

This study aimed at examining the ways in which different athletes may combine the use of several coping strategies and at testing whether perceived goal attainment, affective states, and experience of control would differ across distinctive profiles of coping. A sample of 151 French-Canadian athletes out of 200 who were approached by a research assistant completed l’Inventaire des Strat gies de Coping en Comp tition Sportive (Gaudreau & Blondin, 2002a), the PANAS ( Watson, Clark, & Tellegen, 1988), and a series of items measuring experience of control and perceived goal attainment. Results of a cluster analysis indicated that athletes could be classified in four groups according to their in-competition use of coping strategies. After controlling for athletes’ self-referenced goal attainment, their experience of control, positive affective state, and anger-dejection state differed significantly (p<0.008) across the four profiles of coping. Athletes who have used high level of task-oriented coping in combination with low level of disengagement-oriented coping reported better goal and psychological adjustment than athletes who have used high level of disengagement-oriented coping in combination with low level of task-oriented coping. Overall, these findings suggested that research should move from coping strategies to coping profiles in order to provide a deeper understanding of how different individuals cope with stress.
