The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes (Townsend & Nozawa, 1995). Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.  相似文献

This paper replies to Politzer’s (2007) criticisms of the mental model theory of conditionals. It argues that the theory provides a correct account of negation of conditionals, that it does not provide a truth-functional account of their meaning, though it predicts that certain interpretations of conditionals yield acceptable versions of the ‘paradoxes’ of material implication, and that it postulates three main strategies for estimating the probabilities of conditionals.  相似文献

An active visuo-spatial memory task was used in order to determine the characteristics of mental imagery in subjects with and without visual experience. Subjects were instructed to generate a mental representation of verbally presented 2D patterns that were placed in a grid and to indicate how many pattern elements were in corresponding positions in the two halves of the grid according to a specific grid axis (vertical or horizontal). Unexpectedly, results showed a similar performance in early blind, late blind and sighted subjects. However, subjects' debriefing showed that the three groups used different strategies. The sighted and the late blind subjects took advantage of a visuo-spatial strategy. They generated a mental image of the matrix and they simplified this image to maintain only the relevant information in memory. In contrast, the early blind subjects encoded each pattern element by its location in a (X,Y) coordinate system without visual representation. This indicates that both early and late blind subjects are able to perform an active visuo-spatial imagery task as well as sighted subjects although they use different strategies.  相似文献

A simple view, which dates back to Turing, proposes that complex cognitive operations are composed of serially arranged elementary operations, each passing intermediate results to the next. However, whether and how such serial processing is achieved with a brain composed of massively parallel processors, remains an open question. Here, we study the cognitive architecture for chained operations with an elementary arithmetic algorithm: we required participants to add (or subtract) two to a digit, and then compare the result with five. In four experiments, we probed the internal implementation of this task with chronometric analysis, the cued-response method, the priming method, and a subliminal forced-choice procedure. We found evidence for an approximately sequential processing, with an important qualification: the second operation in the algorithm appears to start before completion of the first operation. Furthermore, initially the second operation takes as input the stimulus number rather than the output of the first operation. Thus, operations that should be processed serially are in fact executed partially in parallel. Furthermore, although each elementary operation can proceed subliminally, their chaining does not occur in the absence of conscious perception. Overall, the results suggest that chaining is slow, effortful, imperfect (resulting partly in parallel rather than serial execution) and dependent on conscious control.  相似文献

共享心智模型:分布、层次与准确性初探   总被引:7,自引:1,他引:6  
共享心智模型理论在理论和应用上已经有20多年的历史了,但它尚留有若干基本问题。共享应当包括多种形式,可从同异质和依赖性的关系上进行分析和测量;共享应是多层次多内容的,包括具体的底层构架和上层的抽象构架,以及指向共享内容的态度和信念;在共享心智的准确性和相似性上,唯一的专家心智模型可能不存在,且共享心智模型的演变发展过程较向专家靠近而言更有意义。共享不是团队过程的简单输出,共享心智模型可能包含一套团队加工过程  相似文献

Recently, an investment model integrating several interdependence-type variables has been proposed to explain commitment in social and organizational settings. The model includes the components of costs, rewards, investments, and alternatives, and has served well in predicting specific outcomes such as job turnover and romantic commitment. The purpose of the present study was to determine the degree to which the investment model can be extended to a new area—commitment to musical activities—and to assess the extent to which commitment profiles generated by the model vary across musical preference groups. Results from a sample of 87 musical devotees demonstrated that the investment model is a valid means of accounting for commitment to participation in musical activities. In addition, distinctive profiles for each group—classical and nonclassical—were identified.  相似文献

双重加工模型认为人类拥有两种信息加工模式,联想模式是快速、不需努力的加工,以良好学习联想(Well-learned associations)为基础:反思模式是慢速的、需要付出努力的加工,建立在基于规则的符号推理基础上,联想模式的发生是自动化的,当预期被违反时,执行反思模式,并需要足够的认知资源.当反思加工没有校正消极的有偏向的联想加工时,就会表现出抑郁的认知易感性.双重加工模型对抑郁认知易感性的评估、病原学和治疗提出了新的看法.  相似文献

A model of the relationship between attitude involvement and attitude accessibilitywas developed and tested. The model specifies that attitude involvement leads to selective(biased) issue-related information-gathering strategies, which in turn produce extreme andunivalent (unambivalent) attitudes. Finally, attitudes associated with univalent and extremeunderlying structures should occasion relatively little decision conflict and thus should be highlyaccessible. Questionnaire response data gathered in a national telephone survey and from twosamples of undergraduates revealed that both attitude extremity and attitude ambivalence onselected political issues mediated the relationship between attitude involvement and attitudeaccessibility. Some findings indicated that selective processing mediated the relationshipbetween attitude involvement and attitude extremity and ambivalence. Discussion focuses on theprocesses linking involvement to accessibility, the factors that moderate theambivalence-accessibility relationship, and the relevance of the model to media-based primingeffects and tothe nature of public opinion and the survey response.  相似文献

An Information Processing Theory of Ambivalence   总被引:1,自引:0,他引:1  
This paper analyzes the sources of ambivalence toward political parties and candidates. We propose and test an information-processing theory of ambivalence in which systematic processing is hypothesized to heighten partisan and candidate ambivalence. We show that ambivalence is linked to several dispositional sources of systematic processing, including individuals' information, motivation, and cognitive style. Specifically, we find that ambivalence tends to be greater among the well informed and those who are high in need for cognition while it tends to be lower among those motivated by directional goals. Collectively, our results suggest that levels of partisan and candidate ambivalence are greatest among those most likely to engage in effortful processing of information and that these effects are independent of value conflict. The results further suggest that the effects of effortful processing on ambivalence are moderated by attitude commitment.  相似文献

First-person narratives are becoming a popular means to communicate health risk information. Although studies show they can increase risk perception and motivate health behaviours compared to statistical messages, more research on the conditions in which they are particularly likely to have effects is needed. In this study, we tested a moderator related to how information is processed. Specifically, we hypothesised that thinking in terms of emotions and personal experiences – known as experiential information processing – would increase people’s responsiveness to a narrative. Female college students (N = 138) who reported indoor tanning were randomly assigned to read a first-person narrative message or a statistical message about the risks of skin cancer. Prior to reading the message, the women received instructions that would activate either experiential or rational information processing. Participants then reported their risk perceptions of skin cancer, worry about skin cancer and behaviour intentions related to skin cancer. Analyses showed that message type and information processing interacted to influence risk perceptions and worry. Consistent with hypotheses, participants reported the highest risk perception and worry when they used an experiential information system prior to reading the narrative message. There were no effects on behaviour intentions. Implications of these findings are discussed.  相似文献

Contributions of the Cognitive Approach to Political Psychology   总被引:2,自引:0,他引:2  
The social cognition tradition has had a strong impact on political psychology scholarship in the last part of the 20th century. The purpose of this essay is to review the contributions of the cognitive approach in helping political psychologists to better understand how citizens think about the world of politics. I consider research concerned with both the mental structure or representation of information about the political world and research concerned with specifying the cognitive processes that produce political judgments and opinion, and conclude that political cognition scholarship has begun to live up to its promise. In the second part of the essay, I suggest a research agenda for the future, pointing to ten directions for extending the political cognition paradigm.  相似文献

A key component of research on human sentence processing is to characterize the processing difficulty associated with the comprehension of words in context. Models that explain and predict this difficulty can be broadly divided into two kinds, expectation-based and memory-based. In this work, we present a new model of incremental sentence processing difficulty that unifies and extends key features of both kinds of models. Our model, lossy-context surprisal, holds that the processing difficulty at a word in context is proportional to the surprisal of the word given a lossy memory representation of the context—that is, a memory representation that does not contain complete information about previous words. We show that this model provides an intuitive explanation for an outstanding puzzle involving interactions of memory and expectations: language-dependent structural forgetting, where the effects of memory on sentence processing appear to be moderated by language statistics. Furthermore, we demonstrate that dependency locality effects, a signature prediction of memory-based theories, can be derived from lossy-context surprisal as a special case of a novel, more general principle called information locality.  相似文献

The adaptability of organisms and human societies depends on the synergistic orchestration of processing modes at many different levels of organization, each with unique informational characteristics. Digital information technology is a narrow transect of this spectrum. Adaptability theory provides a tool for analyzing the interactions between these fundamentally different modes of processing and for delineating the factors that can lead to either positive or negative consequences for human life.  相似文献

Solving complex decision problems is a demanding task; it requires determining and evaluating the consequences of decision alternatives. To this end, uncertain factors that can only partly be influenced by the decision makers, and their interdependencies need to be considered. Scenarios focus on this part of the decision problem; they enable a systematic exploration of a multitude of possible future developments that are relevant for the decision including external events and decisions made. Scenarios are particularly useful when the problem is pervaded by severe uncertainties that cannot be quantified. For the evaluation of alternatives, multiple objectives and the potentially diverging preferences of the involved actors need to be respected. Multi‐criteria decision analysis aims at structuring the problem, evaluating the alternatives and supporting decision makers pursuing multiple goals. We propose an approach integrating scenarios and multi‐criteria decision analysis that focuses on the robustness of alternatives in complex, dynamic, uncertain and time‐bound situations. In this integrated framework, the scenarios provide the basis for evaluating a set of alternatives. Ideally, the set of scenarios considered captures all possible future developments. To appropriately explore this set, formal or analytical approaches to scenario construction generate a large number of scenarios. This challenges the decision makers' information‐processing capacity. To support them in managing the richness of information, a two‐fold approach that uses selection and aggregation is presented. By using a selection method, the scenarios that are deemed most relevant are identified, and their evaluations are presented in detail to decision makers. This approach is complemented by an aggregation of scenario evaluations on the basis of the decision makers' preferences. We present two approaches to facilitate the preference elicitation process.

Feedback and feedback plus points toward a course grade were applied to the attentional behaviors (defined as the ability to identify the semantic base of text passages) of 30 undergraduate students participating in a reading comprehension development program. Correct underlining was increased, extraneous underlining was decreased, and postreading comprehension test scores improved as a result of the procedures. Scores on a standardized test of reading comprehension also increased significantly.  相似文献

Research on individual differences and the framing effect has focused primarily on how variability in rational processing influences choice. However, we propose that measuring only rational processing presents an incomplete picture of how participants are responding to framed options, as orthogonal individual differences in experiential processing might be relevant. In two studies, we utilize the Rational Experiential Inventory, which captures individual differences in rational and experiential processing, to investigate how both processing types influence decisions. Our results show that differences in experiential processing, but not rational processing, moderated the effect of frame on choice. We suggest that future research should more closely examine the influence of experiential processing on making decisions, to gain a broader understanding of the conditions that contribute to the framing effect.  相似文献

Temperamental variables such as trait anxiety are risk factors in children for the development of anxiety disorders. This experiment aimed to test whether temperament moderates the effect of verbal threat information on the physiological component of the fear emotion. An experiment is reported in which 6-10 year old children's (N = 54) fear beliefs about novel animals were measured. They were then given threat, positive or no verbal information about these animals following which their heart rate was recorded while they placed their hands in boxes that they believed these animals inhabited. Children also completed a questionnaire measure of trait anxiety. Child-reported temperament moderated the effect that threat information has on the physiological component of the fear emotion. Fear information is, therefore, a possible mechanism through which temperament leads children to acquire animal fears.  相似文献
