How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.  相似文献

This paper briefly describes the history of the professional interaction between psychoanalysts and analytical psychologists in the United States. There has been little public contact between the two groups since the personal feud between Freud and Jung has beer carried forth to the present generation of analysts. The relationship between Otto Rank and Freud and his circle demonstrated many of the same dynamics that were activated between Freud and Jung, who had broken off their relationship ten years earlier; this paper highlights the similarities between Jung's, then Rank's, exile from the psychoanalytic group, Jung's interest in spiritual matters, including his interest in the nature of religious experience, and his questionable dealing with the Nazis during the 1930s have been the stated reason for the taboo set against Jung's writings. Presently there seems to be a growing realization that there are large areas of mutual interest, and both the similarities and differences between the schools need further exploration.  相似文献

We evaluated strategies to increase behaviors associated with courteous provision of service by 3 staff members of a human service agency. Training included written instructions, practice, and performance feedback. A lottery procedure was introduced to maintain courteous service after training. The results of a multiple baseline design across the 3 participants showed marked increases in courteous behaviors following training. These effects were maintained at 3-, 5-, and 8-month follow-ups. Consumers' satisfaction with service also increased. These findings suggest that simple training and reinforcement procedures can enhance courtesy afforded those who receive service from public and nonprofit organizations.  相似文献

The belief-in-equality construct is defined as the belief that general ability and potential are widely distributed throughout the human population, rather than being limited to an elite minority. Data from a 21-item belief-in-equality inventory and from two construct-validation tasks were gathered using a liberal-arts undergraduate sample of 201 students. Of the two validation tasks, one indicated strong construct validity ( p < .015), however, the second one produced correctly patterned but insignificant results. The results showed that leaders with a high belief in equality put more funds into training their subordinates and had a tendency to delegate more authority to them than leaders with a weak belief in equality.  相似文献

Reports of community alienation and high ingroup identification in the police suggest that they are a particularly ethnocentric group. To empirically test this hypothesis, a sample of urban police officers was surveyed to ascertain their social identity pattern. Results indicated a high level of peer solidarity, community alienation differentiated on the basis of race and social class, and the perception that the source of alienation lies more with the community than with the officers themselves. A central finding was that those officers who identified most strongly with peers also tended to report lower levels of alienation from the community groups. This finding, in conjunction with unremarkable levels of authoritarianism and perceived stress in the sample, challenges the stereotype of the ethnocentric, authoritarian, and stressed out police officer. Results are placed within a novel framework for understanding the police solidarity phenomenon, and implications for police-community relations are discussed.  相似文献

Understanding the mental processes involved in suffering has always been the best basis for communication between patients and caretakers. In this paper we are concerned first with acknowledgment of the existence, generally unknown, and the effects, generally unrecognized, of the hypnotic processes that occur in many forms of suffering, and second with developing our thesis that the understanding and use of hypnotic principles can greatly enrich the chaplain's capacity to alleviate suffering. In this brief presentation we will confine our discussion to the teaching of hypnosis as a virtual necessity in modern clinical training for chaplains. Comments and considerations will precede and follow an outline of the course presently offered at Lenox Hill Hospital [but we cannot here attempt to discuss or explain the fundamentals of hypnotic process or any other aspects of the course content itself]. A basic bibliography is appended for those who wish to know more about hypnosis itself.  相似文献

In this contribution we show how neuroimaging methods can augment behavioural methods to discover processing stages. Event Related Brain Potentials (ERPs), Brain Electrical Source Analysis (BESA) and regional changes in cerebral blood flow (rCBF) do not necessarily require behavioural responses. With the aid of rCBF we are able to discover several cortical and subcortical brain systems (processors) active in selective attention and memory search tasks. BESA describes cortical activity with high temporal resolution in terms of a limited number of neural generators within these brain systems. The combination of behavioural methods and neuroimaging provides a picture of the functional architecture of the brain. The review is organized around three processors: the Visual, Cognitive and Manual Motor Processors.  相似文献

The United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals (1993) directed federal trial judges to preliminarily evaluate the scientific bases of proffered expert evidence. This article presents a decision flowchart for evaluating psychometric data, and attempts to operationalize existing evidentiary standards in hybrid (part science/part law) terms. The resulting framework should better assist courts and forensic experts to understand, evaluate, and apply scientific reasoning in determining the admissibility and probative value of psychometric evidence.  相似文献
