This approach does not define a probability measure by syntactical structures. It reveals a link between modal logic and mathematical probability theory. This is shown (1) by adding an operator (and two further connectives and constants) to a system of lower predicate calculus and (2) regarding the models of that extended system. These models are models of the modal systemS
5 (without the Barcan formula), where a usual probability measure is defined on their set of possible worlds. Mathematical probability models can be seen as models ofS

Several revisions of Atkinson's risk preference model have been proposed in the last 10 years. The advantage of such revisions, shifting the maximum of the approach tendency to the difficult range in predicting choice behavior, is discussed. After summarizing the results of a series of studies on choice behavior in achievement-related situations, the conclusion is drawn that such a revision is unnecessary. Choice behavior is in agreement with the prediction of the original model when expectancies are assessed in the proper way. There may be other good reasons to revise Atkinson's original model. However, the tendency to choose difficulty levels with objective success probabilities less than .50 is not a reason. 相似文献

Detecting phonemes and letters in text: Interactions between different types and levels of processes
In six experiments, subjects detected phonemes or letters in text presented auditorily or visually. Experiments 1 and 2 provided support for the hypothesis that a mismatch between the phoneme and letter representations of a target leads to detection errors. In addition, visual word unitization processes were implicated. Experiments 3 and 4 provided support for the hypothesis that the Gestalt goodness of pattern affected detection errors when subjects searched for letters. Experiments 5 and 6 demonstrated that the effects of unitization on the detection of letters in common words were decreased by altering the familiar configuration of the test words. The combined results of all six experiments lead to the conclusion that both visual and phonetic processes influence letter detection, that these processes communicate through a type of cross-checking, and that there are at least two levels of visual (and perhaps of phonetic) processing involved in the letter detection task. 相似文献

Walter Schneider 《Memory & cognition》1993,21(2):184-192
Biological and computational concepts that underlie the nature working memory are briefly reviewed. The conceptualization of working memory has changed dramatically in the last 30 years. Current biological work has monitored several aspects of memory, including activation decay, sustained activation, long-term connection change, and differential structures for episodic (hippocampal formation) and procedural learning. Current connectionist modeling has identified factors including multiple-region-based processing, control processing as well as data storage, tradeoffs between fast- and slow-connection-change learning effects, and the speeding of acquisition via multiple levels of learning. The need to relate the biological, behavioral, and computational constraints into models of working memory is discussed. Finally, conceptualizations of working memory must acknowledge the need for human learning systems to be robust enough to operate in a dynamic world. 相似文献

We investigated how voluntary confessions, coerced-compliant confessions, and no-confessions influenced guilt assessments in combination with other exculpatory or ambiguous evidence. In three experiments (total N = 808), participants studied case information and provided guilt assessments. As expected, in Experiment 1 and 2a, (i) voluntary confessions to protect a family member elicited stronger guilt attributions than no-confessions and (ii) ambiguous evidence led to stronger guilt attributions than exculpatory evidence. In Experiment 2b, voluntary confessions to protect a group-member (but not to protect a family-member) elicited stronger guilt attributions than no-confessions. Exculpatory eyewitness evidence elicited stronger guilt attributions than exculpatory DNA evidence and participants assigned more weight to exculpatory DNA than eyewitness evidence. Participants were able to discount coerced-compliant confessions when they received information about the interrogations (Experiments 2a/b), but did not consistently consider risk factors for (voluntary) false confessions outside the interrogation room when assessing guilt. 相似文献

With reference to Mead, Peirce, speech act theory, conversation analysis, and Luhmann's phenomenological grounded version of systems theory, the paper tries to reconstruct actions as products of communication. A triadic sequence is identified as the elementary unit for the intersubjective constitution of an act. This unit combines three achievements: (a) the constitution of meaning by sequential attribution, (b) the intersubjective coordination of attributed meanings, and (c) the reproduction of rules, guiding the process of constitution and coordination of attributed meanings. Then, using the tools of systems theory and applying them to empirical results of ethnomethodology and conversation analysis, it is shown how the rule scheme is integrated in a triadic sequence, functioning on three different levels of communication. Finally, a specific form of repair after next turn is discussed, relating it to the function of preserving the structure of conversational types. The analysis of such conversational types opens a possible realm of cooperation between conversation analysis and Luhmann's version of systems theory. 相似文献

The major purpose of this study was to determine the stability across time and social setting of children's social participation and social withdrawal. We followed a sample of Canadian children, aged five years at the beginning of the study, for two years. Children from lower‐SES homes were less involved than those from the higher‐SES in group play after school and during outdoor recess. Across the full sample, social withdrawal was not very stable. There was, however, considerable stability across setting and time among extreme groups of withdrawn participants. Social withdrawal was largely unrelated to parents' initiation of peer contacts for their children. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

Thinking aloud seems unnatural and difficult to most subjects. The present study explored the relation between Ease in Thinking Aloud, verbal fluency, Self-talk, and Big Five personality traits for a heterogeneous sample of 101 German-speaking adults (50 women and 51 men). Ease in Thinking Aloud positively correlated with scores on verbal fluency (r =.31) and Conscientiousness (r =.38). The discussion considers implications for further research on ease in thinking aloud. 相似文献
