The purpose of this article is to propose a conceptual frame of reference for memory research on the basis of two recent lines of development. One such key development is that of a functional orientation of memory research focusing on processing and function rather than structure and memory entities. The other line of development concerns information storage as distributed rather than localized. A functionalistic frame of reference involving a notion of distributed storage is proposed. According to this view remembering is seen as an interaction between available cognitive capabilities and demands of the task in which the individual is remembering something. Encoding is conceived of as an interaction between "affordances" of the environment and "functional dispositions" of the individual. Retrieval is seen as a re-activation of functional dispositions. The formation of unique combinations of functional dispositions plays a crucial role in obtaining perfect recall performance. The viability of the overall conceptual framework is demonstrated in three experimental studies. The development of the design and procedure for these experiments was a second purpose of this paper, namely to outline an experimental setting which could serve as a complement to computer simulations in studying notions of distributed storage. 相似文献

When students are asked to predict the outcome of a random event, where all alternatives are equally probable (lotteries), they tend to choose central, "representative" values, and avoid extreme ones. In ten informal experiments, it is shown how this pattern of choices is influenced by various procedural and structural changes in the basic task. The results show that guessing behavior can be described as a kind of absolute judgment, subject to grouping, anchoring and context effects. Of the two general prediction heuristics originally proposed by Kahneman & Tversky (1973), "representativeness" applies better than "availability". In fact, a major strategy of guessing is apparently to eschew numbers with prominent, "non-random" properties, which at the same time are highly available to the subjects. 相似文献

Probably because of formal advantages, probabilities are often regarded as more basic than other dimensions of attitudes towards uncertain events (beliefs, confidences, doubts, statements of hope and fear, good and bad luck etc.). In a series of experiments, some of these concepts were empirically compared by asking students to give their views on a variety of uncertain events, ranging from future examinations to lotteries. Confidence turned out to be closely related to perceived chance, but very imperfectly to the subjective probability of the event in question, except when all outcomes are judged equally due to chance. Judgments of good and bad luck were still more independent of the probabilities involved, even in a chance situation, It is concluded that subjective probability plays a secondary role in assessments of confidence as well as of luck, and is poorly suited as a common measure of the varieties of subjective uncertainty. A final experiment suggests the subjective and statistical conceptions of uncertainty to have partially opposing connotations. "An uncertain future" seems to be subjectively interpreted as an open future, restricted possibilities of prediction. 相似文献

Abstract.— When asked to estimate the probability of outcomes of draws from a binomial population, student subjects tend to report p values that clearly exceed the objective ones. The probability of specific binomial sequences was found to be even more overestimated, while the answers became much more conservative when the outcomes were grouped into a few categories. These findings were replicated in a second experiment, where the probability of heights in a male and a female student population was estimated. When the task was to estimate frequency of occurrence, instead of probability, the answers became more realistic. The conclusion is drawn that the direct p estimates are relatively independent of frequency judgments, the chief determinant being the properties of the particular sample to be evaluated, irrespective of the number and probabilities of other possible samples. 相似文献

The fundamental components of interpersonal transactions at the nonverbal level often include the cognitively held intention of one person to increase or decrease affiliation with his or her partner, the encoding of this intention into behavioral displays, and the decoding of the behavioral displays by the other. Nonverbal encoding of relational information may be conducted at less than conscious levels of information processing although intentions may be held consciously. A study was conducted in which naive confederates were induced to either increase or decrease their displays of liking for their partner. It was found that confederates’intentions to show increased or decreased liking toward their partners were positively correlated with the partners’liking for the confederate. However, less than one quarter of the confederates could demonstrate an accurate conscious awareness of the behaviors they used and how they used them. Of this small number, those who were given the conscious intention of showing decreased liking demonstrated the most conscious awareness of their nonverbal behaviors. 相似文献
