Predicting human thermal comfort in a transient nonuniform thermal environment.

The National Renewable Energy Laboratory has developed a suite of thermal comfort tools to assist in the development of smaller and more efficient climate control systems in automobiles. These tools, which include a 126-segment sweating manikin, a finite element physiological model of the human body, and a psychological model based on human testing, are designed to predict human thermal comfort in transient, nonuniform thermal environments, such as automobiles. The manikin measures the heat loss from the human body in the vehicle environment and sends the heat flux from each segment to the physiological model. The physiological model predicts the body's response to the environment, determines 126-segment skin temperatures, sweat rate, and breathing rate, and transmits the data to the manikin. The psychological model uses temperature data from the physiological model to predict the local and global thermal comfort as a function of local skin and core temperatures and their rates of change. Results of initial integration testing show the thermal response of a manikin segment to transient environmental conditions.

Conceptual models of psychological distress among low-income patients in an inner-city primary care clinic.

Although depression and anxiety syndromes are common in primary care, many depressed and anxious patients fail to receive effective treatment. Little attention has been given to the role of illness beliefs in shaping these patients' treatment preferences and decisions. Using semistructured interviews, this study examined conceptual models of depressive symptoms among patients in an inner-city clinic. A theoretical taxonomy of patients' conceptual models of distress was developed: each category was associated with a unique pattern of treatment preferences. We conclude that patients' models of distress may play an important role in treatment-seeking decisions, and deserve further investigation.

Tests of multiplicative models in psychology: a case study using the unified theory of implicit attitudes, stereotypes, self-esteem, and self-concept.

Theories that posit multiplicative relationships between variables are common in psychology. A. G. Greenwald et al. recently presented a theory that explicated relationships between group identification, group attitudes, and self-esteem. Their theory posits a multiplicative relationship between concepts when predicting a criterion variable. Greenwald et al. suggested analytic strategies to test their multiplicative model that researchers might assume are appropriate for testing multiplicative models more generally. The theory and analytic strategies of Greenwald et al. are used as a case study to show the strong measurement assumptions that underlie certain tests of multiplicative models. It is shown that the approach used by Greenwald et al. can lead to declarations of theoretical support when the theory is wrong as well as rejection of the theory when the theory is correct. A simple strategy for testing multiplicative models that makes weaker measurement assumptions than the strategy proposed by Greenwald et al. is suggested and discussed.

Power and clinical psychology: a model for resolving power-related ethical dilemmas.

This article considers power in clinical psychology. It is argued that power is present at every level of clinical psychologists' practice and can be used positively and negatively. Drawing on organizational, ethical, psychological, and personal influences, a heuristic problem-solving model for the process of understanding and resolving power-related ethical dilemmas is proposed. It is contended that such a model provides a humane and systematic process of understanding and working through power-related ethical dilemmas. It is argued that resolving power-related ethical issues cannot be achieved through the statement of absolute values but rather requires a process of understanding, action, and review. The model is used to draw out implications for promoting ethical practice and preventing the abuse of power in clinical psychology.

Breast implants and illness: a model of psychological factors.

Studies of disease outcomes have not produced an explanation or an intervention for the symptoms and complaints that some women have attributed to breast implants. Reviews of the literature have found no increased risk of specific systemic disease, and no treatment recommendations have emerged. However, similar symptoms in fibromyalgia, chronic fatigue, and other contexts have been considered to be stress or behaviourally mediated, and a number of promising behavioural interventions have been developed. Aetiological, research, and treatment implications may follow from the consideration of such symptoms within a behavioural medicine model that allows for the interaction of physical and psychological influences. In the case of implants, a mass somatisation model may also help to discern the potential effects of litigation and other social influences.

Mind from genes and neurons: a neurobiological model of Freudian psychology.

A hypothetical neurobiological model of Freud's architecture of the mind is presented in an attempt to unify concepts and data derived from molecular biology (e.g., genomic imprinting), systems neuroscience (e.g., neuroanatomochemical circuitries), evolutionary psychology (e.g., human mating strategies), and Freudian psychology. The model posits that events related to genomic imprinting can be regulated in a tissue-specific manner over the course of neural development such that imprinting along the matriline would favor the development of corticostriatal structures whereas imprinting along the patriline would favor the development of limbic-subcortical structures. A neuropsychological analysis of the brain requirements for successful mating presumably would put an evolutionary premium on the corticostriatal system (matrilineal) in men and limbic-subcortical systems (patrilineal) in women. Additionally, the model emphasizes that the ego and the super-ego of Freudian psychology are dependent on corticostriatal mechanisms (matriline-related), while the id is dependent on brainstem processes (patriline-related). It is hoped that the model herein presented has heuristic value for a rapprochement of psychoanalysis and neurobiology.

[Eating disorders in a health-psychology approach: model of pathogenic processing of cognitive information].

A new theoretical approach of cognitive information processing in eating disorders is introduced. It is based on the system theory with a view on health psychology. We are going to emphasize the deviations in the self-concept, the role of procedural memory in body image disturbance and the content of working memory supporting the appearance of cognitive dysfunctions in eating disorders. Despite the long-standing interest in eating disorders a coherent body of empirically supported knowledge that can be used to direct clinical practice, has yet to emerge. Although there are many possible causes of this limited progress, one important source of difficulty is that research completed to date has tended to be based on clinical models of psychopathology lacking a sound theoretical framework. The complex multidimensional nature of the model shows several possibilities of prevention and intervention in eating disorders.

Race, psychopathy and the self: a discourse analytic study.

This discourse analytic study explores the implicit psychological models articulated within the admission reports of black and white men admitted to a forensic hospital under the diagnostic category of psychopathy. The white admission reports reproduce a traditional psychological model of the self in which intra-psychic states are causally linked to external behaviour whilst the black reports de-emphasize internal states and stress the relevance of the external world in influencing psychological equilibrium. The influence of these models upon the experience of psychopathology is discussed and it is argued that they are directly relevant to the (seemingly) paradoxical underepresentation of black men under the medico-legal category of psychopathy.

[No therapy possible? A group therapy model for psychologically disturbed and socially disadvantaged children].

The authors have developed a group therapy model specifically for children who are difficult to treat using traditional psychotherapeutic techniques. In the present article they describe this model, which has been employed successfully for the past four years in an elementary school in an area of high social deprivation, in collaboration with teaching staff and a social worker.

Global model analysis by parameter space partitioning.

To model behavior, scientists need to know how models behave. This means learning what other behaviors a model can produce besides the one generated by participants in an experiment. This is a difficult problem because of the complexity of psychological models (e.g., their many parameters) and because the behavioral precision of models (e.g., interval-scale performance) often mismatches their testable precision in experiments, where qualitative, ordinal predictions are the norm. Parameter space partitioning is a solution that evaluates model performance at a qualitative level. There exists a partition on the model's parameter space that divides it into regions that correspond to each data pattern. Three application examples demonstrate its potential and versatility for studying the global behavior of psychological models.

A biopsychobehavioral model of risk of severe hypoglycemia.

Severe hypoglycemia (SH) is a significant problem for many patients with type I diabetes and presents a major barrier to optimal diabetes control. A critical task facing diabetes research is to understand, predict, and reduce the risk of SH in insulin-treated patients. The purpose of this article is to propose a biopsychobehavioral model of SH risk that integrates and extends previously proposed models. Current biological and psychological models of SH risk, which focus on hormonal counterregulation and symptom awareness, are reviewed. The limitations of these models are also discussed, including their failure to recognize important psychological and behavioral processes that contribute to SH risk. Specifically, the biopsychobehavioral model includes patients' decision-making, judgment, and behavioral responses as significant predictors of SH risk. The proposed model is comprised of seven steps: 1) physiological and behavioral precursors to low blood glucose (BG), 2) low BG occurrence, 3) hormonal and neurological responses to low BG, 4) awareness of symptoms caused by hormonal and neurological changes, 5) detection of low BG, 6) decision-making and judgment, and 7) behavioral response. The model has several advantages, including the ability to mathematically calculate the transitional probabilities from each step to the next as well as the ability to describe SH risk in both hypoglycemia-aware and hypoglycemia-unaware patients. Research findings supporting the biopsychobehavioral model are presented, and its empirical and clinical implications are discussed.

Optimism, pessimism, and positive and negative affectivity in middle-aged adults: a test of a cognitive-affective model of psychological adjustment.

This study attempted to address limitations in the understanding of optimism and pessimism among middle-aged adults. Specifically, a model of affectivity as a mediator of the link between outcome expectancies and psychological adjustment (life satisfaction and depressive symptoms) was presented and examined in a sample of 237 middle-aged adults. Consistent with a mediation model, results of path analyses indicated that optimism and pessimism (particularly the former) had significant direct and indirect links (by means of positive and negative affectivity) with depressive symptoms and life satisfaction. These results add to the small but growing literature identifying optimism and pessimism as important concomitants of psychological adjustment in more mature adults.

Dissociation in hypnosis and multiple personality disorder.

The first part of this paper examines the concept of dissociation in the context of hypnosis. In particular, the neodissociative and social psychological models of hypnosis are compared. It is argued that the social psychological model, in describing hypnotic enactments as purposeful, does not adequately distinguish between behavior that is enacted "on purpose" and behavior that serves or achieves a purpose. 2 recent dissertations (Hughes, 1988; Miller, 1986) from the University of Waterloo are summarized, each of which supports the neodissociative view that hypnotic behavior can be purposeful (in the sense that the suggested state of affairs is achieved) and nonvolitional (in the sense that the suggested state of affairs is not achieved by high level executive initiative and ongoing effort). The second part of the paper employs a neodissociative view of hypnosis to help understand the current epidemic of multiple personality disorder (MPD). In particular, it is argued that many symptoms of MPD are implicitly suggested effects--particularly prone to occur in persons who have a lifelong tendency to use dissociative type defenses. The present author believes that this account is easier to sustain conceptually and empirically than the current view, which states that a secondary (tertiary, etc.) personality accounts for the striking phenomenological discontinuities experienced by MPD patients.

[A model for psychological assessment of mobbing].

The phenomenon "mobbing" has been studied scientifically for twenty years. In this period, researchers have elaborated progressively more complex explanations for it. Despite the attempts to examine mobbing closely, and to define it accurately, further investigation, aimed at quantifying the factors that characterize it, is still needed. This study proposes a method for assessing mobbing and the personality features linked to it. The model was tested on a sample of 29 outpatients (19 males, 10 females) asking medical assistance for work-related psychopathological problems. Focusing on the occupational history and work environment, a psychological diagnosis (DSM IV-axis I) was made for 27 of them: 14 cases of generalized anxiety disorder, 6 subjects with depressive disorder, 1 dysthymic disorder, 1 post-traumatic stress disorder, 2 cases of adaptation disorder, 3 patients with personality disorder. Although the number of the examined subjects is limited, the proposed model seems to be utilizable in the clinical practice.

Self-assessment in clinical health psychology: a model for ethical expansion of practice.

Society expects autonomous professions to ensure the competency of it practitioners, and professions should facilitate the continuing education and training of its members. Given the shift from psychology as a mental health profession to that of a health profession, the authors propose a self-assessment model for the individual practitioner to gauge his or her readiness to provide professional service in expanded areas of practice. This model could also be useful to the American Psychological Association, state psychological associations, and other purveyors of continuing education programs in systematically developing postgraduate experiences. A template for self-assessment that reflects well-accepted core domains of knowledge and skills is presented.
