Natural categories   总被引:2,自引:0,他引:2  
The hypothesis of the study was that the domains of color and form are structured into nonarbitrary, semantic categories which develop around perceptually salient “natural prototypes.” Categories which reflected such an organization (where the presumed natural prototypes were central tendencies of the categories) and categories which violated the organization (natural prototypes peripheral) were taught to a total of 162 members of a Stone Age culture which did not initially have hue or geometric-form concepts. In both domains, the presumed “natural” categories were consistently easier to learn than the “distorted” categories. Even when not central, natural prototype stimuli tended to be more rapidly learned and more often chosen as the most typical example of the category than were other stimuli. Implications for general differences between natural categories and the artificial categories of concept formation research were discussed.  相似文献

Thresholds play a critical role in linking judgments and choices. One way they do so is by dividing a continuous judgment variable, such as probability, into two regions that imply different choices and actions, such as operate/do not operate, admit/do not admit, or invest/do not invest. We examine this link by focusing on the tendency of professional decision makers to adjust their thresholds when the risks associated with negative decision outcomes are elevated. We report two studies involving experienced auditors that investigate thresholds in a “going-concern” setting. In this setting, the auditor assesses the probability that a business firm will be unable to continue in existence for the coming year; if that probability exceeds a “substantial doubt” threshold (also assessed by the auditor), the auditor is required to disclose the relevant information in the firm’s annual report to the public. Our studies use two experimental cases based on actual business firms that differ in their objective likelihoods of not continuing as going concerns. We derive the auditors’ substantial doubt thresholds from the relationship between their probability assessments and their disclosure choices, unlike all prior research which has simply asked auditors to state the probability they believe represents substantial doubt. We find that auditors’ derived thresholds are adjusted downward for the more problematic firm, a result that we attribute to the asymmetric loss functions inherent in going-concern settings. The second study has some of the auditors directly provide their substantial doubt thresholds (SDTs). The downward adjustment is again found for derived thresholds but not for elicited thresholds, suggesting that the method of capturing thresholds may be an important issue in understanding judgment and choice.  相似文献

With an interdisciplinary approach to understanding human psychosocial development and behavior, psychologists in academic medical settings have much to offer in the areas of administration, research, teaching, and service, including in the realm of organizational systems and behavior within medical schools. In these ways, psychologists can play a large role in the fulfillment of the mission of academic medicine and enhance psychology’s stature in the medical school organization. Two case studies are presented that exemplify the varied roles and responsibilities of psychologists in a medical school. To be successful within medical schools, the following generalizable principles are offered: (1) “add value” to the medical school by demonstrating the diverse and relatively unique abilities of psychologists; (2) be flexible and adaptive to the different requirements of medical academic settings; (3) make a concerted effort to work well with medical students, residents, and physicians who may not be well-versed in certain aspects such as rigorous research methodology and statistics; and (4) find a “good match” between one’s strengths, the needs of the medical setting, and the attributes of the M.D. leader. With such an approach, remarkable accomplishments can be made.  相似文献

Criticize measurement-based personality research by recounting a well-known limitation: indices of relationship are often inflated because of the similarity of content across measures of presumably different constructs. In this paper we endorse the major contention of Nicholls et al. that measurement-based research may be conducted thoughtlessly, and we extend their thinking by pointing out an important underlying issue—the problem of defining what constitutes a “syndrome.” In contrast to them, however, we argue that the problems in measurement they cite do not entail the consequences they foresee and, in addition, have limited application.  相似文献

In “Tropes and Ordinary Physical Objects”, Kris McDaniel argues that ordinary physical objects are fusions of monadic and polyadic tropes. McDaniel calls his view “TOPO”—for “Theory of Ordinary Physical Objects”. He argues that we should accept TOPO because of the philosophical work that it allows us to do. Among other things, TOPO is supposed to allow endurantists to reply to Mark Heller’s argument for perdurantism. But, we argue in this paper, TOPO does not help endurantists do that; indeed, we argue that anyone who accepts TOPO should reject endurantism.  相似文献

Much discussion of meaning by philosophers over the last 300 years has been predicated on a Cartesian first-person authority (i.e. “infallibilism”) with respect to what one’s terms mean. However this has problems making sense of the way the meanings of scientific terms develop, an increase in scientific knowledge over and above scientists’ ability to quantify over new entities. Although a recent conspicuous embrace of rigid designation has broken up traditional meaning-infallibilism to some extent, this new dimension to the meaning of terms such as “water” is yet to receive a principled epistemological undergirding (beyond the deliverances of “intuition” with respect to certain somewhat unusual possible worlds). Charles Peirce’s distinctive, naturalistic philosophy of language is mined to provide a more thoroughly fallibilist, and thus more realist, approach to meaning, with the requisite epistemology. Both his pragmatism and his triadic account of representation, it is argued, produce an original approach to meaning, analysing it in processual rather than objectual terms, and opening a distinction between “meaning for us”, the meaning a term has at any given time for any given community and “meaning simpliciter”. the way use of a given term develops over time (often due to a posteriori input from the world which is unable to be anticipated in advance). This account provocatively undermines a certain distinction between “semantics” and “ontology” which is often taken for granted in discussions of realism.  相似文献

Reviews ways in which the author’s program of research has been influenced by Tellegen’s (1991) conceptualization of personality traits as both real and biologically based entities. Analyses of longitudinal-epidemiological data on personality and criminal behavior indicate that personality measures and measures of criminal behavior can be conceived of as indicators of a latent, stable propensity to act in an unconstrained manner. In addition, an unconstrained personality style, substance dependence, and antisocial behavior can be modeled as indicators of a highly heritable propensity towards “externalizing” or acting-out behaviors, with environmental factors playing a key role in determining the specific way in which this general, heritable externalizing propensity is expressed. Such research outlines the value of concepts from personality psychology in understanding consequential behaviors in the population at large.  相似文献

I write this short essay in response to Peirce, as a feminist, pragmatist, and cultural studies scholar, in the hope that it will help to bring feminism and pragmatism together. I suggest that Peirce offers marginalized and colonized people a way to argue for the importance of their input, with his theory of fallibilism, even if he still claims a position of privilege. He also offers assistance through his concept of “a community of inquirers.” It is curious that Peirce’s definition of a university argues for a split between theory and practice that his earlier work sought to heal. Peirce opened a door to help diverse scholars be able to enter the university, and find a way to address issues of power, with his youthful connecting of theory to practice, that his more senior position draws our attention away from and seeks to hold off. Fortunately, it is too late. Peirce’s youthful pragmatism has been developed in important ways by other scholars and now serves as an example of a way to do philosophy that does connect theory to practice and does seek to address real problems in diverse peoples lives, and help to find solutions that effect change.  相似文献

Over the past three decades, research into the developmental course by means of which persons come to an increasingly mature conception of the knowing process has yielded an highly defracted picture. Despite some concert of opinion about the general bill of particulars, what remains deeply problematic is the increasingly radical disagreement that has arisen regarding the ages at which major milestones in the course of epistemic development are said to be reached. As a way of making some sense of these competing claims, it is argued that the emerging insight that knowledge is ineluctably shaped by those doing the knowing (i.e., that there is an unavoidable “world-to-mind direction of fit” (J.R. Searle, Intentionality: An Essay in the Philosophy of Mind, Cambridge University Press, Cambridge, 1983) between things in the world and the manner of their understanding) does not arrive in a single piece. Instead, as the data presented here help to illustrate, an appreciation of the constructed character of knowledge more commonly arrives piecemeal and at different ontogenetic moments, the times of which are governed by the place that different objects of knowledge occupy along an envisioned continuum of diverse epistemic contents. On this account, not all “facts of the matter” are ordinarily seen to occupy the same epistemic footing. Rather, some so-called facts are commonly understood to be of an “institutional” sort, where “representational” diversity is early expected and widely tolerated. By contrast, other objects of knowledge are imagined to be more like “brute” facts that, on some less mature readings, fully escape the clutches of subjective opinion. Viewed against the backcloth of this proposed continuum, a developmental sequence hypothesized according to which growing persons first come to view “institutional” facts as humanly constructed before subsequently coming to a similar view about presumptively “brute” facts. To test this hypothesis, 242 young persons were administered a paper and pencil measure of epistemic reasoning (the EDQ). Results strongly support the hypothesis that respondents understood the interpretive nature of beliefs about “institutional” facts at an earlier age than so-called “brute” facts.  相似文献

The author responds to the commentaries of 13 experts on his 1980 American Psychologist article, “Investigation and its discontents: On some constraints on progress in psychological research.” Among the themes addressed are the role of theory in psychological research, the meanings and implications of “productivity” by scholars and researchers, the role of grants, and of money in general, in directing research efforts, and the relation between psychological and neuropsychological research.  相似文献

Two experiments test the hypothesis that social value orientation influences choice and recall of heuristics in individuals preparing for negotiation. Consistent with predictions, Study 1 shows that in the preparation phase, negotiators with a prosocial value orientation choose more cooperative heuristics (e.g., “equal split is fair”) than competitive heuristics (e.g., “your gain is my loss”) while negotiators with a competitive social value orientation do the reverse. Negotiators with an individualistic social value orientation do not discriminate in their choice between cooperative and competitive heuristics. Study 2 shows that following preparation, prosocial negotiators recall more cooperative than competitive heuristics while individualists and competitors do the reverse. Additional measures suggest that prosocial negotiators prefer cooperative heuristics because these are seen as morally appropriate, whereas individualists and competitors prefer competitive heuristics because these are seen as effective.  相似文献

In this article I argue that the concept of gender is misunderstood by the majority of psychologists. Increasingly the term “gender” is mindlessly replacing the term “sex,” obfuscating decades of theory and research that elucidated gender as a complex social-psychological variable rather than a bifurcated individual-difference variable tied to biological sex. As a consequence, gender is largely ignored as an “active” variable in counseling research and practice. Current theory and research on gender as they apply to counseling and psychotherapy are first described. Then ways in which gender processes are often reproduced in counseling and psychotherapy and factors contributing to this practice are illuminated. Finally, areas particularly vulnerable to reproducing gender are described and some examples provided of the reproducing, and the disrupting, of gender processes in counseling.  相似文献

Basic research into the prevalence, natural course, and phenomena of comorbidity of depressive disorders during childhood are reviewed and implications of this research for treating depressed youths are noted. Results of investigations into the biological aspects of depression are integrated into a multifactorial model of depressive disorders during childhood and the efficacy of pharmacological interventions is discussed. Cognitive theory is integrated with attachment theory to explain a possible avenue to the development of depressive disorders during childhood. Interpersonal therapy has emerged as a potentially effective intervention for depressed youths. Basic tenets of this treatment model are compared and contrasted to a cognitive-behavioral treatment model, and a hybrid treatment referred to as “cognitive therapy within the interpersonal context” is proposed.  相似文献

A new thematic (TAT) measure of intimacy motivation was developed and cross-validated in four separate arousal studies using three different college populations. A brief sketch of the derived thematic scoring system for intimacy motivation was presented. The goal state of the intimacy motive was defined as experiencing a warm, close, and communicative exchange with another person. In a college sample, subjects scoring high on the intimacy motive were rated by friends and acquaintances as significantly more “warm,” “natural,” “sincere,” “loving,” and “appreciative” and less “dominant,” “outspoken,” and “self-centered” than subjects scoring lower. The results were discussed in terms of the theories of Sullivan on the need for interpersonal intimacy, Maslow on growth motivation and “B-love,” Bakan on communion, and Buber on the I-Thou relation. Differences between the new coding system and the need for Affiliation (n Aff) system for scoring imaginative productions were also suggested.  相似文献

Adequate access to child and adolescent mental health services for young people in high need populations is an important concern of service systems researchers and program evaluators. We present results of a statewide study of access to community mental health services for eight populations of special concern. The analysis relied exclusively on existing databases in conjunction with innovative statistical techniques to provide comprehensive measures of access to care. Our findings indicate that access to care varied substantially across special populations, although children and adolescents in each of our eight “special populations” had greater access to public mental health services than members of the general population of the state. The interpretation of the findings and directions for future research are discussed.  相似文献

Using a large data base of 20,725 questionnaires from 19 European countries, this article uses a combination of factor analysis and tree based regression to determine driver groups with homogeneous self-reported behavior and determine whether regional differences in driving behaviors exist. Self-reported behavior, including speeding, reckless driving, seat belt use, and drinking and driving are examined. The results suggest that speeding and general reckless (dangerous) behavior are related, perhaps capturing a driver's “risk taking” or “pre-trip violations” behavior. Similarly, seat belt use and driving under the influence of alcohol are also related and may represent a driver's “law abiding” tendency or “during-trip violations” behavior. Further, important regional differences and similarities between European drivers are uncovered. Northern European drivers report a significantly higher compliance with drinking and driving laws and seat belt use regulations than do Southern and Eastern European drivers.  相似文献

This experiment examined the impact of messages about uniqueness and similarity between groups of people on Black and Latino children's social attitudes. Children (ages 11–14) read two brief science books embedded with a similarities message (“all people are basically the same”), unique message (“each person is unique”), combined similar-unique message (“all people are the same in a way, but each person is also unique”), or no additional message (control). Relative to the other conditions, the combined condition increased general social tolerance and decreased desired social distance from White children. No message appeared to negatively impact participants' attitudes toward their own group. Implications of these results for basic and applied anti-bias work on promoting similarities, differences, or both are discussed.  相似文献

Much research has demonstrated the “vicious cycle” of low self-esteem in nonsocial task performance settings. The present study explores the possibility that social situations may also provide opportunities for low (and high) selfesteem individuals to respond in ways that maintain their self-image. More specifically, it has been shown that low self-esteem individuals believe that others like them to a lesser extent than do high self-esteem persons; such beliefs are bound to perpetuate individuals' self-esteem levels. This study is designed to investigate whether the self-perceptions of either or both groups are consistent with reality (as measured by others' actual liking for them), or are merely reflective of the perceiver's attitude. Unacquainted, opposite sex dyads completed self-esteem and self-likability measures before engaging in a “getting acquainted” conversation. Participants then rated their liking for their partners and estimated their partners' liking for them. Relative to high self-esteem participants, low self-esteem subjects rated themselves as less likable prior to the conversation and estimated that their partners liked them to a lesser extent after the conversation. However, low self-esteem subjects were actually rated by their partners as equally likable as the high self-esteem participants. Alternative explanations, limitations, and implications are discussed.  相似文献

Two inferential routes allow children to produce expectations about new instances of ontological categories like “animal” and “artefact.” One is to generalise information from a “look-up table” of familiar kind-concepts. The other one is to use independent expectations at the level of ontological domains. Our experiment pits these two sources of information against each other, using a sentence-judgement task associating properties with images of familiar and unfamiliar artefacts and animals. “Strange” properties are compatible with the ontological concept, but not encountered in any familiar kind. A look-up strategy would lead children to reject them and an independent expectation strategy to accept them. In both domains, we find a difference in reaction to strange properties associated with familiar vs. unfamiliar items, which shows that even young children do use independent domain-level information. We also found a U-shaped curve in propensity to use such abstract information. In addition, animal categories are the object of much more definite domain-level expectations, which supports the notion that the animal domain is more causally integrated than the artefact domain.  相似文献
