William James's essay The Will to Believe proposed that we are sometimes justified, even obligated, to believe from our strong emotional or passional nature that something is true, even though there may not be total logical, evidential proof—which he also wrote is not to be found in this world. This essay explores situations, using a recent dear-death experience (NDE) example, in which there are reasonable evidence and logic, and yet belief seems to be withheld. I postulate and discuss nonrational influences producing resistance to belief, including the fear of being in error, the fear of rejection from the scientific community, irrational requirements of logicality, avoidance of consequences, and paradigm fixation. I also discuss issues in philosophy of science and epistemology in regard to proof. 相似文献

During on-line language production, speakers rapidly select a sequence of words to express their desired meaning. The current study examines whether this lexical selection is also dependent on the existing activation of surface properties of the words. Such surface properties clearly matter in various forms of wordplay, including poetry and musical lyrics. The experiments in this article explore whether language processing more generally is sensitive to these properties. Two experiments examined the interaction between phonological and semantic features for written and verbal productions. In Experiment 1, participants were given printed sentences with a missing word, and were asked to generate reasonable completions. The completions reflected both the semantic and the surface features of the preceding context. In Experiment 2, listeners heard sentence contexts, and were asked to rapidly produce a word to complete the utterance. These spontaneous completions again incorporated surface features activated by the context. The results suggest that lexical access in naturalistic language processing is influenced by an interaction between the surface and semantic features of language. 相似文献

Most classification research focuses on cases in which each abstract feature has the same surface manifestation whenever it is presented. Previous research finds that people have difficulty learning to classify when each abstract feature has multiple surface manifestations. These studies created multiple manifestations by varying aspects of the stimuli irrelevant to the abstract feature dimension. In this article, multiple manifestations were created by varying aspects of the stimuli relevant to the abstract feature dimension. People given categories with the family resemblance category structure often used in psychology experiments had difficulty learning to classify when multiple manifestations were present, even though the variation was relevant. This effect was reversed when a family resemblance structure with nondiagnostic values was used. 相似文献

Category use and category learning 总被引:24,自引:0,他引:24
Categorization models based on laboratory research focus on a narrower range of explanatory constructs than appears necessary for explaining the structure of natural categories. This mismatch is caused by the reliance on classification as the basis of laboratory studies. Category representations are formed in the process of interacting with category members. Thus, laboratory studies must explore a range of category uses. The authors review the effects of a variety of category uses on category learning. First, there is an extensive discussion contrasting classification with a predictive inference task that is formally equivalent to classification but leads to a very different pattern of learning. Then, research on the effects of problem solving, communication, and combining inference and classification is reviewed. 相似文献

This article explores the cognitive underpinnings of interpersonal closeness in the theoretical context of "including other in the self" and, specifically, the notion of overlap between cognitive representations of self and close others. In each of three studies, participants first rated different traits for self, close others (e.g., romantic partner, best friend), and less close others (e.g., media personalities), followed by a surprise source recognition task (who was each trait rated for?). As predicted, in each study, there were more source confusions between traits rated for self and close others (e.g., a trait rated for self recalled as having been rated for the close other) than between self (or close others) and non-close others. Furthermore, several results suggest that the greater confusions between self and close others are due specifically to interpersonal closeness and not to greater familiarity or similarity with close others 相似文献

The author compared simulations of the "true" null hypothesis (zeta) test, in which sigma was known and fixed, with the t test, in which s, an estimate of sigma, was calculated from the sample because the t test was used to emulate the "true" test. The true null hypothesis test bears exclusively on calculating the probability that a sample distance (mean) is larger than a specified value. The results showed that the value of t was sensitive to sampling fluctuations in both distance and standard error. Large values of t reflect small standard errors when n is small. The value of t achieves sensitivity primarily to distance only when the sample sizes are large. One cannot make a definitive statement about the probability or "significance" of a distance solely on the basis of the value of t. 相似文献

Immediately after a stimulus appears in the visual field, there is often a short period of facilitated processing of stimuli
at or near this location. This period is followed by one in which processing is impaired, rather than facilitated. This impairment
has been termed inhibition of return (IOR). In the present study, the time course of this phenomenon was examined in two ways.
(1) A graphical metaanalysis plotted the size of the effect as a function of the stimulus onset asynchrony (SOA) of the two
stimuli. This analysis showed that IOR is impressively stable for SOAs of 300-1,600 msec. It also showed that the literature
does not provide any clear sense of the duration of IOR. (2) An empirical approach was, therefore, taken to fill this gap
in our knowledge of IOR. In three experiments, IOR was tested using SOAs between 600 and 4,200 msec. IOR was robust for approximately
3 sec and appeared to taper off after this point; the observed duration varied somewhat as a function of the testing conditions.
In addition, for the first second, the degree of inhibition was inversely related to distance of the target from the original
stimulus, but for the next 2 sec this spatial distribution was not observed. Theories of the mechanisms and function of IOR
must conform to these spatial and temporal properties. 相似文献

The present study examined the organization of preparatory processes that underlie set switching and, more specifically, switch costs. On each trial, subjects performed one of two perceptual judgment tasks, color or shape discrimination. Subjects also responded with one of two different response sets. The task set and/or the response set switched from one to the other after 2-6 repeated trials. Response set, task set, and double set switches were performed in both blocked and randomized conditions. Subjects performed with short (100-msec) and long (800-msec) preparatory intervals. Task and response set switches had an additive effect on reaction times (RTs) in the blocked condition. Such a pattern of results suggests a serial organization of preparatory processes when the nature of switches is predictable. However, task and response set switches had an underadditive effect on RTs in the random condition when subjects performed with a brief cue-to-target interval. This pattern of results suggests overlapping task and response set preparation. These findings are discussed in terms of strategic control of preparatory processes in set switching. 相似文献

Much attention has been focused in recent years on the ethical acceptability of physicians receiving gifts from drug companies. Professional guidelines recognize industry gifts as a conflict of interest and establish thresholds prohibiting the exchange of large gifts while expressly allowing for the exchange of small gifts such as pens, note pads, and coffee. Considerable evidence from the social sciences suggests that gifts of negligible value can influence the behavior of the recipient in ways the recipient does not always realize. Policies and guidelines that rely on arbitrary value limits for gift-giving or receipt should be reevaluated. 相似文献

Alternate administration methods were tested for the Socialization (So) subscale of the California Psychological Inventory (CPI; H. G. Gough, 1994; H. G. Gough & P. Bradley, 1996) in 437 young adult men. One method administered the 46 CPI-So items in isolation from the CPI, whereas the 2nd method administered the 46 items embedded in the CPI. External validity measures of antisociality were also administered over the 2 sessions. Isolated administration produced somewhat higher internal consistency and significantly better concurrent validity and demonstrated construct validity as a measure of antisociality. Additional factor analytic studies of the CPI-So and CPI revealed that the 2 CPI-So versions had different factorial structures and that the embedded CPI-So subscale did not retain factorial integrity or an appreciable amount of reliable and uniquely interpretable variance. 相似文献
