Summary

Cognitive science approaches can inform research in traumatic stress studies by articulating separate scientific issues that may be relevant to understanding alterations in memory and awareness for trauma. This article will first address general issues about disrupted memory and “knowledge isolation” for trauma, as well as introduce specific aspects of “betrayal trauma theory” (Freyd 1994, 1996) that inform our understanding of memory impairment. According to betrayal trauma theory, a potent motivation for knowledge isolation (including amnesia, dissociation, and unawareness) in the face of trauma is to preserve apparently necessary human relationships in which betrayal occurs. Results from three recent laboratory investigations of cognitive processes associated with dissociative tendencies are summarized. These laboratory investigations suggest that the attentional capacities of high dissocators are impaired under conditions of selective attention, but not divided attention. Furthermore, in our laboratory tasks high dissocators have impaired memory for emotionally charged words associated with sexual assault and abuse (e.g., “incest”) but not neutral words, as compared with low dissociators. The findings suggest that high dissociators use divided attention and multi-tasking as a way to control the flow of information. Such a view is consistent with betrayal trauma theory. Though in its infancy, this research draws on cognitive science and observations of traumatic response and offers much promise.  相似文献

In this article I am concerned with analogical reasoning in ethics. There is no doubt that the use of analogy can be a powerful tool in our ethical reasoning. The importance of this mode of reasoning is therefore commonly accepted, but there is considerable debate concerning how its structure should be understood and how it should be assessed, both logically and epistemically. In this paper, I first explain the basic structure of arguments from analogy in ethics. I then discuss the diversity of analogical arguments that can be found in ethics. I analyse their structure, assess them from a logical viewpoint, and show how they can be epistemically challenged and defended. The result of this investigation is that, contrary to a commonly held view, analogical reasoning can be a logically valid type of ethical reasoning that can provide reasons for action that are not worse than the reasons provided by any other kind of practical reasoning.  相似文献

This study investigated whether performance on the card playing task (Newman, Patterson, & Kosson, 1987) and the moral/conventional distinction measure predict level of childhood conduct problems as indexed by the Psychopathy Screening Device (Frick & Hare, in press). The card-playing task indexes the child's sensitivity to changes in reinforcement rate. The moral/conventional distinction measure indexes the child's sensitivity to the difference between moral transgressions which result in harm to another from conventional transgressions which more usually result in social disorder. The Psychopathy Screening Device indexes a behavioral syndrome that consists of two dimensions: affective disturbance and impulsive and conduct problems. Thirty-nine children with emotional and behavioral difficulties were presented with both measures. Performance on both measures did predict extent of behavioral disturbance. Moreover, there was a significant association between performance on the card playing tasks and the moral/conventional distinction. The results are interpreted within the response set modulation and violence inhibition mechanism models and by reference to recent work at the anatomical level.  相似文献

Pragmatics in Analogical Mapping   总被引:1,自引:0,他引:1  
Theories of analogical reasoning differ in the roles they ascribe to pragmatic factors as a source of constraints on analogical mappings. The multiconstraint theory as instantiated in the ACME model (Holyoak & Thagard, 1989a) claims that pragmatic constraints interact with structural and semantic constraints within the mapping stage itself, in addition to influencing pre-mapping and post-mapping stages. Participants in three experiments were asked to generate mappings between non-isomorphic analogs for which mappings for some elements were ambiguous on structural grounds. In all experiments, manipulations of participants’ processing goals influenced their preferred mappings. At the same time, goal-irrelevant information contributed to many-to-one mappings (Experiments 1 and 2) and to the resolution of mappings that were ambiguous on the basis of goal-relevant information alone (Experiment 3). The qualitative pattern of results was successfully simulated using the ACME model, implementing the impact of processing goals as an inhibitory process of selective attention.  相似文献

Analogies must be symmetric. If a is like b, then b is like a. So if a has property R, and if R is within the scope of the analogy, then b (probably) has R. However, analogical arguments generally single out, or depend upon, only one of a or b to serve as the basis for the inference. In this respect, analogical arguments are directed by an asymmetry. I defend the importance of this neglected – even when explicitly mentioned – feature in understanding analogical arguments.  相似文献

Analogical transfer is the ability to transfer knowledge despite significant changes in the surface features of a problem. In categorization, analogical transfer occurs if a classification strategy learned with one set of stimuli can be transferred to a set of novel, perceptually distinct stimuli. Three experiments investigated analogical transfer in rule-based and information-integration categorization tasks. In rule-based tasks, the optimal strategy is easy to describe verbally, whereas in information-integration tasks, accuracy is maximized only if information from two or more stimulus dimensions is integrated in a way that is difficult or impossible to describe verbally. In all three experiments, analogical transfer was nearly perfect in the rule-based conditions, but no evidence for analogical transfer was found in the information-integration conditions. These results were predicted a priori by the COVIS theory of categorization.  相似文献

The use of an analogy from a semantically distant domain to guide the problemsolving process was investigated. The representation of analogy in memory and processes involved in the use of analogies were discussed theoretically and explored in five experiments. In Experiment I oral protocols were used to examine the processes involved in solving a problem by analogy. In all experiments subjects who first read a story about a military problem and its solution tended to generate analogous solutions to a medical problem (Duncker's “radiation problem”), provided they were given a hint to use the story to help solve the problem. Transfer frequency was reduced when the problem presented in the military story was substantially disanalogous to the radiation problem, even though the solution illustrated in the story corresponded to an effective radiation solution (Experiment II). Subjects in Experiment III tended to generate analogous solutions to the radiation problem after providing their own solutions to the military problem. Subjects were able to retrieve the story from memory and use it to generate an analogous solution, even when the critical story had been memorized in the context of two distractor stories (Experiment IV). However, when no hint to consider the story was given, frequency of analogous solutions decreased markedly. This decrease in transfer occurred when the story analogy was presented in a recall task along with distractor stories (Experiment IV), when it was presented alone, and when it was presented in between two attempts to solve the problem (Experiment V). Component processes and strategic variations in analogical problem solving were discussed. Issues related to noticing analogies and accessing them in memory were also examined, as was the relationship of analogical reasoning to other cognitive tasks.  相似文献

Analogical Processes in Language Learning   总被引:1,自引:0,他引:1  
ABSTRACT— The acquisition of language has long stood as a challenge to general learning accounts, leading many theorists to propose domain-specific knowledge and processes to explain language acquisition. Here we review evidence that analogical comparison is instrumental in language learning, suggesting a larger role for general learning processes in the acquisition of language.  相似文献

The influences of surface and structural similarity on analogical transfer were examined with 318 undergraduate participants in four experiments using Needham and Amado's (1995) Pythagoras THOG problem as the source problem and Wason's standard abstract THOG task as the target problem. In Experiments 1-3, systematic changes in surface similarity between the source and target problems were introduced by changing the named exemplar, the dimensional values, and the dimensions, respectively, in the target problem. Significant transfer was obtained in all three experiments. In Experiment 4, we explored the basis of this transfer by examining three versions of the Pythagoras THOG problem, factorially combining its facilitating features as source problems. Results indicated that the inclusion of a hypothesis generation request was necessary for significant transfer. The implications of our findings for using transfer versus facilitation as the performance criterion for deductive reasoning are considered.  相似文献

The ability to reason by analogy is particularly important because it permits the extension of knowledge of a target domain by virtue of its similarity to a base domain via a process of analogical inference. The general procedure for analogical inference involves copying structure from the base to the target in which missing information is generated, and substitutions are made for items for which analogical correspondences have already been found. A pure copying with substitution and generation process is too profligate to be useful, and so constraints must be placed on what information is to be carried over. In this paper, the importance of systematicity as a constraint on inference is explored in four studies in which subjects find correspondences between domains and also make inferences. This work suggests that people prefer to make inferences of information connected to systematic correspondences between domains. A second important theme of this paper is that violations of one-to-one mapping can lead to inconsistent object substitutions in inference. The data reveal no such inconsistent substitutions in people's inferences, suggesting that they do respect one-to-one mapping in analogical inference. These findings are discussed relative to four prominent computational models of analogical mapping and inference.  相似文献

Egalitarians sometimes analogize socioeconomic opportunities to starting gates, playing fields, and the results of a lottery. A fair game is one in which all have an equal opportunity to succeed; egalitarians propose that the same is true of a fair society. A second type of argument for egalitarianism appeals to intuitions about the distribution of found resources. A just division of manna discovered on a strange planet seems to be an equal one. Both types of argument share a crucial feature: they concern the once‐off division of a fixed sum of goods. I argue that the most compelling reasons to depart from an equal division of goods derive from the economic activity involved in producing more of those goods, e.g., Pareto improvements due to efficiency gains that result from incentives that encourage production. We cannot conclude that game analogies and found resources cases arbitrate in favour of equality against non‐egalitarian principles because they exclude precisely those considerations that provide the strongest reasons to reject equality.  相似文献
