It is suggested that molar streams of behavior are constructed of various arrangements of three elementary constituents (elicited, evoked, and emitted response classes). An eight-cell taxonomy is elaborated as a framework for analyzing and synthesizing complex behavioral repertoires based on these functional units. It is proposed that the local force binding functional units into a smoothly articulated kinetic sequence arises from temporally arranged relative response probability relationships. Behavioral integration is thought to reflect the joint influence of the organism's hierarchy of relative response probabilities, fluctuating biological states, and the arrangement of environmental and behavioral events in time.  相似文献

Abstract. The recently suggested reformulation of Darwinian evolutionary theory, based on the thermodynamics of self-organizing processes, has strong philosophical implications. My claim is that the main philosophical merit of the thermodynamic approach, made especially clear in J.S. Wicken's work, is its insistence on the law-governed, continuous nature of evolution. I attempt to substantiate this claim following a historical analysis of beginning-of-the-century ideas on evolution and matter-life relationship, in particular, the fitness-of-the-environment-for-life theory of the Harvard physiologist L.J. Henderson. In addition, I point to an epistemological common ground underlying the studies of the “thermodynamics school” and other currently active research groups focusing on the emergence and evolution of biological organization.  相似文献

This paper situates Bogdanov in the context of social theory generally and socialist theory in particular. It outlines briefly the principal characteristics of his mature system, and assesses the strengths and weaknesses of his approach to the fundamental problems of social thought. The paper devotes particular attention to the problem of just how systems develop from less complex to more complex forms of organization, and evaluates Bogdanov’s solution to this problem against the background of populist, social democratic, and Leninist alternatives.  相似文献

Agonistic interactions between adult domestic rabbit females were observed. Females were housed in groups of four in outdoor enclosures measuring 4 × 4 m. Agonistic patterns included aggression (AG), flight (FL), and submission (SB). Observations focused on 1) initial interactions between unfamiliar females, concomitant with the formation and establishment of a social structure (Phase 1); and 2) interactions between familiar females organized in a stable social structure (Phase 2). AG was frequent between unfamiliar females and appeared related to the acquisition of social dominance. When social organization was settled, there was a dramatic reduction in the number and frequency of aggressive behaviors. Similarly, FL was more frequent when females were unfamiliar, but it did not appear to be merely a response to AG. The decreased frequency of both AG and FL in Phase 2 was paralleled by an increased frequency of SB with respect to FL. Under stable social conditions, subordinate females frequently signalled submission to dominant counterparts. In contrast, the latter did not signal their social status with any consistent behavioral pattern. It follows that SB was not necessarily induced as the appropriate response to aggression given by dominant females. Thus, SB appeared relevant in social communication especially in structured groups, where it conveyed information on the actor's subordination and possibly inhibited the receiver's aggression. A further possibility is that it has an autonomous rather than secondary role in the maintenance of stable dominance/subordination relationships.  相似文献

Systematic information processing and decision-making under uncertainty are key constructs of new conceptions explaining the severity of pathological worry. The current study attempted to analyze their usefulness in subclinical and clinical groups. In the first phase of the study (N = 251) participants were examined with the Penn State Worry Questionnaire (PSWQ), a GP consultationrelated survey, and a screening survey for generalized anxiety disorder (GAD). In the second phase (N = 220), the State-Trait Anxiety Inventory, the PSWQ, and tasks measuring systematic information processing (SIP) versus heuristic reasoning (HR) were applied. In the third phase (N = 60), GAD (n = 30) and healthy control (n = 30) groups were examined with the above methods and the Iowa Gambling Task (IGT). In the low risk group, a relationship between mood and the representativeness heuristic (ρ = 0.50), as well as anchoring and adjustment heuristic (anxiety-related stimuli) was found (ρ = −0.53). In the GAD group, significant correlations between the PSWQ score, the IGT loss avoidance score (ρ = 0.40), and total IGT score (ρ = 0.48) were found. The results did not confirm a particular usefulness of the systematic/heuristic information processing construct in subclinical and clinical groups. Theory-consistent results were rather found in the nonclinical groups. Nevertheless, the data revealed some interesting findings supporting potential explanatory power of some theoretical models.  相似文献

This work evaluated the prospect that organizational accounts of the retention of list information by monkeys might be an artifact of familiarity with conditional relationships. Seven sophisticated macaques were trained on four five-item lists. Each acquisition selectively excluded one of the internal conditional pairs of the typical four-problem sequence (AB,BC,CD,DE) that defines a five-item serially ordered list. Then, all possible novel pairings and the trained pairs appeared together in a test. After this, the previously omitted pair was trained and animals were retested. On all tasks, initial tests revealed little organization and much intersubject variability of characteristic choice strategies, but subsequent inclusion of all four conditional pairs always yielded organized serial choice. On both the four-problem tests and in a later retention, errors were directly related to interitem distance between the objects paired on test trials. These results helped to specify the conditions required for demonstration of non-human primate analogs of transitivity, and showed that even sophisticated monkeys organize information in retention only if they know all interitem relationships.

通过比较超声、宫腔镜检查与病理诊断子宫内膜息肉的结果,以及超声诊断结果阴性的病例中,宫腔镜与病理诊断的差异检出率,探讨宫腔镜检查对正确诊断子宫内膜息肉的重要性.回顾性收集连续在我院妇科行宫腔镜检查且证实子宫内膜息肉诊断的住院患者共730例.总结各病例超声诊断、宫腔镜检查及病理诊断的结果.统计分析显示,三者诊断子宫内膜息肉的检出率分别为82.7%、93.4%、90.8%.其中,由超声检查漏诊的子宫内膜息肉患者共126例,宫腔镜及病理检出率分别为96.8%、88.1%,且两者的阴性结果互不重叠,这种诊断差异在超声诊断结果示内膜增厚/内膜厚薄不均病例中尤为显著.因此,子宫内膜息肉的诊断方式中,宫腔镜诊断检出率最高,但仍有漏诊的病例由病理确诊,研究认为宫腔镜检查是确诊子宫内膜息肉的重要诊断方法.  相似文献

The rapid growth of employee assistance Programmes (EAPs) has not been matched by the accompanying research base of their efficacy. Given the inconsistent information relating to the effectiveness of EAPs in enhancing employee and organizational outcomes, the present review systematically appraised available evidence from organizational psychology and business databases and grey literature sources. A total of 17 studies examining the impact of EAPs, met the inclusion criteria. These were mostly from North America and utilized quantitative methodology and pre- and post-intervention designs. The majority of studies focused on EAPs offered by external providers and the counselling service, with the most common limitations being discrepancies in variable definitions and an absent comparable control group. Overall, this review found that utilizing EAPs enhanced employee outcomes, specifically improving levels of presenteeism and functioning. Absenteeism was most commonly investigated but produced mixed results. Presenteeism demonstrated a stronger effect size and greater improvement than absenteeism, suggesting presenteeism as a better variable for assessing EAP effectiveness. This review clarified parameters of existing evidence and highlighted the narrow range of measures used to date, omitting important constructs such as health and well-being and productivity. A broader evaluation capturing a wider range of variables is urgently needed.  相似文献

目的:探讨适应性自恋与病理性自恋对个体心理健康的不同影响。方法:750名大学生完成了一套由自恋人格问卷(NPI)、病理性自恋量表(PNI)和症状自评量表(SCL-90)组成的测验。利用结构方程模型对变量间的关系进行分析。结果表明:病理性自恋的二阶因子自恋易损性对个体心理健康具有显著的负向预测作用,自恋易损性水平越高,个体心理健康水平越低。自恋夸大性和适应性自恋(自恋人格问卷,NPI)对心理健康的正向预测作用达到边缘显著,自恋夸大性和适应性自恋得分越高,心理健康水平越高。结论:病理性自恋的二阶因子自恋易损性对心理健康具有明显的破坏作用,而自恋夸大性和正常/适应性自恋可能对心理健康存在微弱的保护作用。  相似文献
