恐惧管理理论的争议及其对死亡心理研究的启示

死亡心理是人类面临死亡及相关事件时所产生的认知、情感和行为意向的复杂心理状态。目前, 研究死亡心理较为全面和科学的理论是恐惧管理理论(Terror Management Theory, 简称TMT)。但该理论存在以下争议: (1)在死亡的基本认知方面, 恐惧管理理论呈现出不一致的研究结果, 如死亡是否与不确定性无关, 死亡是否导致恐惧情绪, 寻求个体生存是否为人类的核心议题; (2)在社会文化层面, 恐惧管理理论提出者的文化背景对待死亡的普遍态度是呈否认的, 但是跨文化的研究显示其他文化背景对待死亡的态度却呈现出接纳或蔑视; (3)在恐惧管理理论的研究结果方面, 呈现出较多的矛盾性, 表明研究中有重要的调节因子未被涉及。基于此, 死亡心理可能的研究方向拟从认知、行为和社会三个层面进行梳理。未来死亡心理研究需秉承科学与文化并重的原则, 并结合死亡心理的内容与过程, 关注群体面对死亡时的心理规律, 开展死亡心理影响下的身心健康干预研究。     

The nature of sexual reinforcement.

Sexual reinforcers are not part of a regulatory system involved in the maintenance of critical metabolic processes, they differ for males and females, they differ as a function of species and mating system, and they show ontogenetic and seasonal changes related to endocrine conditions. Exposure to a member of the opposite sex without copulation can be sufficient for sexual reinforcement. However, copulatory access is a stronger reinforcer, and copulatory opportunity can serve to enhance the reinforcing efficacy of stimulus features of a sexual partner. Conversely, under certain conditions, noncopulatory exposure serves to decrease reinforcer efficacy. Many common learning phenomena such as acquisition, extinction, discrimination learning, second-order conditioning, and latent inhibition have been demonstrated in sexual conditioning. These observations extend the generality of findings obtained with more conventional reinforcers, but the mechanisms of these effects and their gender and species specificity remain to be explored.     

Designing interventions that include delayed reinforcement: implications of recent laboratory research

The search for robust and durable interventions in everyday situations typically involves the use of delayed reinforcers, sometimes delivered well after a target behavior occurs. Integrating the findings from laboratory research on delayed reinforcement can contribute to the design and analysis of those applied interventions. As illustrations, we examine articles from the Journal of the Experimental Analysis of Behavior that analyzed delayed reinforcement with respect to response allocation (A. M. Williams & Lattal, 1999), stimulus chaining (B. A. Williams, 1999), and self-control (Jackson & Hackenberg, 1996). These studies help to clarify the conditions under which delayed reinforcement (a) exercises control of behavior, (b) entails conditioned reinforcement, and (c) displaces the effects of immediate reinforcement. The research has applied implications, including the development of positive social behavior and teaching people to make adaptive choices.

A thought on the nature of psychoanalytic theory

In this paper I suggest that much of recent experiment in analytic theory, even widely diverse approaches, has a common denominator the problem of the conceptual vacuum created by the shift away from a central creative position of the idea of psychic mechanisms. I try to illustrate, by comparing theories of Bion and George Klein, that this movement seems to point in the direction of considering now what is uniquely psychoanalytic about our theories. I content that what is unique about psychoanalytic theories is that they are involved in the experiential core-function of the applied science by becoming internalized and used symbolically to aid the analyst inwardly to endure persecutory anxiety and loss of the sense of objective reality, and so maintain the analytic position.     

From theory to application and back again: implications of research on medical expertise for psychological theory.

Research directed at an understanding of medical expertise is about 30 years old, and many developments in this literature parallel progress in cognitive psychology. Over the past 15 years or so, this research became much more closely identified with particular psychological theories. Initial forays into medicine were essentially direct applications of methods developed in the psychology lab to the more natural domain of medicine, with varying degrees of success. These attempts were followed by a second wave that took the psychological theories themselves more seriously in a more thoughtful application of psychological methods to the medical domain. I will argue in the present paper that the methods and theories used in the study of medical expertise have advanced to the point that there is some reverse flow and they are providing a unique and valuable perspective on the nature of thinking.     

A theory about the nature of Evil

This article raises the nature of Evil as a dimension of spiritual reality and indicates some experience-based and some theologically based perspectives on the nature of Evil. The author offers a new perspective on the nature of Evil based on an extension of earlier work on a six-factor model of spirituality.     

Decision theory,reinforcement learning,and the brain

Decision making is a core competence for animals and humans acting and surviving in environments they only partially comprehend, gaining rewards and punishments for their troubles. Decision-theoretic concepts permeate experiments and computational models in ethology, psychology, and neuroscience. Here, we review a well-known, coherent Bayesian approach to decision making, showing how it unifies issues in Markovian decision problems, signal detection psychophysics, sequential sampling, and optimal exploration and discuss paradigmatic psychological and neural examples of each problem. We discuss computational issues concerning what subjects know about their task and how ambitious they are in seeking optimal solutions; we address algorithmic topics concerning model-based and model-free methods for making choices; and we highlight key aspects of the neural implementation of decision making.     

A molar theory of reinforcement schedules

Behavior of subjects exposed to concurrent and individual interval and ratio schedules of reinforcement may be described in terms of a set of expressions relating the value of responses to their durations, a feedback equation relating reinforcement to response duration, and the assumption that subjects allocate their time among various responses so as to maximize value.     

An analysis of reinforcement sensitivity theory and the five-factor model

Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) are two prominent personality accounts that have emerged from different backgrounds. Although the two accounts are applied to similar research topics, there is limited empirical work examining the correspondence between them. The current study explored the relationship between RST-based personality traits and the FFM domains and facets in an undergraduate sample (n = 668). Regression analyses indicated that Sensitivity to Punishment (SP) was positively associated with Neuroticism and Agreeableness, and negatively associated with Extraversion, Openness, and Conscientiousness. In contrast, Sensitivity to Reward (SR) was positively associated with Extraversion and Neuroticism, and negatively associated with Agreeableness and Conscientiousness. Exploratory analyses at the facet level specified the relationship between SP, SR, and each domain. A factor analysis was also conducted to explore the higher-order factor structure of RST and the FFM domains. Three factors emerged, which we labelled SP, Stability-Impulsivity, and Sensation Seeking. Taken together, these findings suggest that there is substantial overlap between these two accounts of personality. Copyright © 2007 John Wiley & Sons, Ltd.
