Effects Of Histories Of Differential Reinforcement Of Response Rate On Variable-interval Responding

Three pigeons were exposed first to multiple differential-reinforcement-of-high-rate and differential-reinforcement-of-low-rate schedules that were correlated with green and red keys, respectively, and then were shifted to a variable-interval schedule arranged on a white key. In subsequent test sessions, the variable-interval schedule continued to operate, but green and red keys replaced the white key in alternate sessions. In Part 1 of the experiment, the variable-interval schedule correlated with the white key was introduced immediately after the multiple-schedule condition, and the test condition began 15 days later. This sequence was repeated twice, with a reversal of the correlation of the key colors with the components of the multiple schedule at the start of each new cycle. Part 2 added a 6-month break between the multiple-schedule history and the white-key variable-interval schedule followed by test sessions. The procedure was then repeated with a reversal of the correlation between key colors and multiple-schedule components. In the test sessions of Part 1, all pigeons consistently responded faster in the presence of the key color most recently correlated with the differential-reinforcement-of-high-rate contingency than during the color most recently correlated with the differential-reinforcement-of-low-rate contingency. Similar but smaller effects were observed in Part 2. The effects of the reversals in these two parts of the experiment showed that only the most recent contingency exerted an influence on subsequent responding. The data suggest that this effect of the most recent history continues to operate on behavior under current contingencies even after a long lapse of time.     

儿童病因认知发展的研究

对儿童病因认知发展的研究具有重要的理论和实践意义。近20年来,西方发展心理学家在该领域的研究逐渐从皮亚杰理论框架下的研究转变为“朴素理论”框架下的研究。在理论上,研究越来越强调领域特殊性;在研究思路上,研究逐渐从“自上而下”的研究转变为“自下而上”的研究;在研究方法上,研究不断降低任务难度,提高了任务的区分度和敏感性。该领域进一步的研究将更为深入和细致的探查儿童的病因认知。

The Hypothesis Of Ether And Reid's Interpretation Of Newton's First Rule Of Philosophizing

My object is to question a recurrent claim made to the point that Thomas Reid (1710–1796) was hostile to ether theories and that this hostility had its source in his distinctive interpretation of the first of Newton's regulæ philosophandi. Against this view I will argue that Reid did not have any quarrel at all with unobservable or theoretical entities as such, and that his objections against actual theories concerning ether were scientific rather than philosophical, even when based on Newton's first rule. I argue further that Reid's insistence on Newton's rule concerns, not direct observation, but rather the notion of explanation itself.     

Comparison Of Narratives Of Loss Experiences Of World War Ii and Vietnam Combat Veterans

Abstract

While their continuing grief now is receiving periodic media attention, for years and even decades, American soldiers who fought in World War II (WWII) and who fought in Vietnam have suffered their life-altering experiences of loss in silence. Many of the WWII generation now have died and cannot share their grief with us. We as scholars of loss and trauma have a special obligation to reach out to the living survivors of WWII for information about their experiences. As has been often noted (e.g., Kuenning, 1990), for years after the conclusion of the Vietnam War, the stories of loss and grief of Vietnam veterans were not welcomed. The purpose of this chapter is to report some comparative narrative evidence from veterans of these two wars. Our major question was whether strong differences between groups in perceived long-term impact of combat experience would be reported.     

Loss Of Trust: Correlates Of The Comorbidity Of Ptsd and Severe Mental Illness

Abstract

The prevalence of post-traumatic stress disorder (PTSD) in the general population of the United States is a topic of speculation, with estimates ranging from 0.4% to 9% (Breslau, Davis, Andreski, & Peterson, 1991; Helzer, Robins, & McEvoy, 1987; Kessler, Sonnega, Bromet, Hughes, & Nelson, 1995). Likewise, estimates of the prevalence of PTSD within the population of persons with serious mental illness have varied widely, depending on how PTSD has been measured. While record verification of PTSD within mental health outpatient samples has routinely been very low (0%-3%), research assessments of PTSD have resulted in estimated rates of co-occurrence of 29% to 43% (Cascardi, Mueser, DeGirolomo, & Murrin, 1996; Craine, Henson, Colliver, & MacLean, 1998; Mueser et al., 1998). A lack of documentation of PTSD in clinical records and inattention to PTSD in clinical diagnoses are thought to greatly underestimate the extent of PTSD within mental health treatment populations. The general consensus among researchers has been that the occurrence of PTSD is much higher within the population of persons with diagnoses of mental illness than in the general population, particularly among those who have major depression (Friedman & Rosenheck, 1996).     

Some Characteristics Of The G Index Of Agreement

Several uses of the G index of agreement are discussed for both Q- and R-techniques. It is shown that the index is meaningful and is not sensitive either to changes in having direction (for profile analysis) or to marginal inequalities for dichotomous data.     

Of Power

Written in 1792 and not previously published, this essay sets out Reid's considered view of the nature of agency and the related idea of natural causation. Locke is wrong in supposing that the idea of power is acquired through external or internal experience, Hume in supposing that because it is not got through outer or inner sense we have no such idea. The primary conception of power is that of personal agency, got from the experienced fact that certain events are produced when we will to produce them. The concept of cause is related to this through the experience of the efficacy of volitional power. The problem, then, is what to make of the idea that nature contains non-volitional causes. An orderly world implies the operation of an intelligent agent. The idea of agency proper implies two-way operation, e.g., to be possessed of the power of walking is thereby to be possessed of the power of not walking. So a power does not necessitate a certain outcome, and what we think of as necessitating natural causes are related to natural regularities, rather than part of the idea of causality as such.

心理理论研究的毕生取向

心理理论经典研究范式主要关注的是3～5岁年龄的儿童。随着研究的不断深入,学者们开始逐渐把眼光投向人的生命全程,表现在：开始考察4岁以前儿童有关心理理论的问题;尝试对自5岁直到老年期的心理理论发展情况进行探讨;提出了心理理论的毕生发展观。心理理论研究的毕生(life-span)取向已初露端倪,该取向将是今后心理理论领域研究的重要发展方向之一。     

On A Semantic Interpretation Of Kant's Concept Of Number

What is central to the progression of a sequence is the idea of succession, which is fundamentally a temporal notion. In Kant's ontology numbers are not objects but rules (schemata) for representing the magnitude of a quantum. The magnitude of a discrete quantum 11...11 is determined by a counting procedure, an operation which can be understood as a mapping from the ordinals to the cardinals. All empirical models for numbers isomorphic to 11...11 must conform to the transcendental determination of time-order. Kant's transcendental model for number entails a procedural semantics in which the semantic value of the number-concept is defined in terms of temporal procedures. A number is constructible if and only if it can be schematized in a procedural form. This representability condition explains how an arbitrarily large number is representable and why Kant thinks that arithmetical statements are synthetic and not analytic.

A Compatibilist Version Of The Theory Of Agent Causation

The Theory of Agent Causation has always been formulated as an incompatibilist view, but I think that this has been a mistake. The aim of this paper is to argue that, contrary to what agent causation theorists and their opponents have always believed, the most plausible version of the Theory of Agent Causation is actually a compatibilist version of that theory. I formulate the traditional version of the Theory of Agent Causation, and consider a series of objections to it and related views. With each objection comes a corresponding revision of the theory that is motivated by that objection, and with each revision the theory becomes increasingly compatibilistic until, finally, we arrive at a completely compatibilistic version of the Theory of Agent Causation, which I take to be the most plausible version of that theory.     

谈判心理研究发展述评

20世纪60年代和70年代,谈判是社会心理学研究中一个非常活跃的领域。但70年代后期,谈判研究因认知心理学的兴起而衰落。80年代早期,谈判这一领域在心理学研究中再度兴起,谈判的行为决定研究成为这一时期主流。但90年代后期谈判的社会心理学研究复兴,一度消失的社会因素再次成为谈判研究的热点。该文回顾了西方谈判心理研究的发展,探讨了导致谈判心理研究发展中所发生的诸多变化的原因,并展望了其将来的发展方向。
