Two studies assessed response time among clinically anxious subjects and normal controls when presented with threat, positive and neutral stimuli under perceptual (lexical decision) and semantic (category decision) task conditions. In Study 1, panic disorder subjects' (n = 14) performance was compared to that of matched normal controls (n = 14) while in Study 2 social phobic subjects (n = 24) were compared to matched normal controls (n = 24). Relative to matched normal controls, panic disorder subjects but not social phobics tended to show greater slowing in performance on the more cognitively complex (category) task. A second finding, consistent across both studies was that, compared to the normal control groups, both panic and social phobic groups showed significantly slowed responses to threat words in both the perceptual and semantic tasks. Such findings are directly counter to the predictions of a mood congruence hypothesis. This apparent contradiction is resolved by a review of the literature which indicates that mood-related facilitation effects are obtained only in tasks which tap awareness of threat information rather than speed of response. It is suggested that while anxiety may produce enhanced awareness of threat, it may inhibit responsiveness to it. The results of these studies are seen as consistent with ethological theories of inhibited motoric responses under certain threat conditions. Furthermore, the findings suggest that caution is indicated in interpreting slowed reaction time to threat stimuli in tasks such as the Stroop color naming task as purely the result of attentional processes. 相似文献

Summary We have seen that the theory of the evolution of the universe is very remote from being matter of absolute knowledge as its popular presentation today would have us believe. Moreover, it is based on a certain aspect of reality, namely, that of science, which cannot pretend to be the only one possible and thus to exclude the religious aspect of the world as a creation by God. The same is true regarding the evolutionary theories of life by Eigen or Vollmert, both being based on polymeric chemistry. If, therefore, Vollmert confesses, as already quoted, that he is not afraid to accept a creating God as an alternative to Darwinism, so in this respect he speaks despite everything as a believer and not as a scientist. By no means do I deny that the scientific results of Vollmert which seem to reveal the mystery of life to us can strengthen our faith — but never can faith be based on it. Faith springs from another source.Despite that, we can say today that the situation has changed principally, because both the philosophy of science and the discussions of the theories of evolution have shaken that kind of naive belief in science which in contrast to former times has turned theology into the ancilla, the maid of science.On the other hand, it would be a great misunderstanding to assume that now we can simply turn the tables. The criticism which I have partly put forward against the modern theories of evolution cannot obscure the numerous discoveries of the highest importance which are connected with them. These discoveries have provided us with an immensely deepened knowledge both of the physical conditions of the universe and of the chemical foundations of life. To conclude, I want to quote an American scientist who said: I am as confused as before — but on a much higher level. And this, I think, is the best summary of the present situation. 相似文献

The concept of sin seems to have virtually disappeared from the pastoral counseling literature, and this likely reflects the possibility that it has virtually disappeared from the practice of pastoral counseling. This article presents a case for returning the concept of sin to pastoral counseling and does so by discussing the psychospiritual importance of addressing sin, defining sin in a pastorally useful way, discussing four capital sins in light of a contemporary understanding of sin, and drawing some pastoral implications. 相似文献

We prove that all proofs in -logic (a first order logic with -rule added) in which -rule is used finitely many times can be turned into proofs in which the -rule is used at most one time. Next, we prove that the word finitely above cannot be changed by the word infinitely. 相似文献

According to decision theory, the rational initial action in a sequential decision-problem may be found by ‘backward induction’ or “folding back’. But the reasoning which underwrites this claim appeals to the agent's beliefs about what she will later believe, about what she will later believe she will still later believe, and so forth. There are limits to the ‘depth’ of people's beliefs. Do these limits pose a threat to the standard theory of rational sequential choice? It is argued, first, that the traditional solutions of certain games depend on knowledge which exceeds depth limits, and that these solutions therefore cannot be shown rational in the usual sense. Then, for that related reason even ‘folding back’ solutions of one-person problems cannot be! A revision of our notion of rational choice is proposed, analogous to the reliabilist account of knowledge of Goldman and others, by which this paradox is resolved. 相似文献

The essential activity of group therapy consists of members taking an interest in each other by asking questions, showing concern, and conveying understanding. When members have not done this it has often been taken as a sign of resistance. A review of the research on helping suggests that there are four social factors that affect assistance giving in groups: 1) ambiguity-often people fail to give help because they are uncertain about who should give it, what should be done, and how it should be done; 2) often help is not given because of the way in which problems are presented; 3) the social comparisons that individuals make affect help-giving; and 4) there are costs associated with providing assistance. This discussion suggests that leaders can facilitate interaction among group members as teachers who clarify and as indirect helpers who redirect concerns back to group members. 相似文献

This study explored patterns emerging in videotaped sessions of group psychotherapy with seven outpatients of a large mental health facility. The 22 sessions spanned the 12th to 27th months of the group's existence. Group members had long histories (25–50 years) of symptoms characteristic of schizophrenia. Each session was rated on the Group Environment Scale. One session from a group in its earlier stages was also rated on the same instrument to give some indication of baseline patterns. Analyses of changes across the 15 months were not statistically significant. However, some GES subscales, including Cohesion, Independence, and Self-Discovery, showed relatively high mean levels across the 15-month period. These elevations are discussed as suggesting the codevelopment of orientations that have sometimes been viewed as incompatible and unattainable for schizophrenics. Interpreted clinically, the GES patterns help to elaborate recent findings about the relatively good success of long-term group therapy with such populations. The study, although merely suggestive, illustrates the potential for gleaning solid and clinically useful data from group psychotherapy research.The authors would like to thank Drs. Jill Rierdan, Nina Fieldsteel, Joseph Christy, and an anonymous reviewer for their suggestions, Kendra Bryant for serving as the reliability rater, and Janet Eltinge for her skilled videotaping. 相似文献

Human analog tests of object permanence were administered to various breeds of adult dogs (Canis familiaris). Experiment 1 showed that the performance of terriers, sporting, and working dogs did not differ. Dogs succeeded in solving invisible displacement problems, but performance was lower than in visible displacement tests. Familiarity with the task had some influence because invisible displacement tests were more successful if they were preceded by visible displacement tests. In Experiment 2, odor cues from the target object and the hiding screens were available or were masked. Results confirmed that success was lower in invisible than in visible displacement tests and that these problems were solved on the basis of representation of visual information rather than on the basis of olfactory cues or of local rule learning. Dogs are compared with other species that display Stage 6 object permanence. 相似文献

This study sought to investigate the effects of mild head injury on a particular type of cognitive ability, verbal analogical
reasoning. The performance of 19 individuals with head injuries was compared to a group of 30 control subjects matched for
age, education, and gender on 100 verbal analogies. Solution times and error rates were modeled. Unstandardized regression
weights for individual subjects were correlated with subjects’ performance on a number of standardized ability tests. Results
showed that compared to the control subjects, the head injured subjects: (a) were significantly slower to solve the analogies,
and were particularly slow to perform certain processes: encoding/inference and comparison; (b) tended to show greater variability
in performance; and (c) had data that had a poorer componential model fit. The data suggest that analogical reasoning is affected
by a head injury, and that certain information processes may be responsible for performance deficits. 相似文献
