Summary Following Mr. Bixby and some other 19th century scientist– philosophers such as Claude Bernard, relevant scientific actions
should, as a matter of primary importance, be explained with reference to the competence and not to the intentions of those
involved. The background is a reliabilist virtue approach – a widespread tendency in 19th century epistemology and philosophy
of science. Bixby’s approach includes a critique of some constructivist arguments and establishes a mutually supportive connection
to conceptions of scientific progress. 相似文献

In the present study, we examined whether the detection advantage for negative-face targets in crowds of positive-face distractors
over positive-face targets in crowds of negative faces can be explained by differentially efficient distractor rejection.
Search Condition A demonstrated more efficient distractor rejection with negative-face targets in positive-face crowds than
vice versa. Search Condition B showed that target identity alone is not sufficient to account for this effect, because there
was no difference in processing efficiency for positive- and negative-face targets within neutral crowds. Search Condition
C showed differentially efficient processing with neutral-face targets among positive- or negative-face distractors. These
results were obtained with both a within-participants (Experiment 1) and a between-participants (Experiment 2) design. The
pattern of results is consistent with the assumption that efficient rejection of positive (more homogenous) distractors is
an important determinant of performance in search among (face) distractors. 相似文献

Attentional interference arising from emotional pictures was examined. Participants had to ignore emotional pictures while solving math problems (Study 1, N = 126) or detecting the location of a line (Study 2, N = 60). Data analyses tested predictions of 3 theories. Evolutionary threat theory predicts interference by snake pictures. Categorical negativity theory predicts interference by negative pictures regardless of their intensity. According to arousal theory, arousal level predicts interference effects. The results supported arousal theory, with the most arousing pictures (strong unpleasant pictures, oppositesex models) producing the strongest interference. The findings are interpreted in the context of process models of emotions that postulate an initial relevance check before further processing of valence and other appraisal dimensions. 相似文献

In the past few years, ideas of Social Identity Theory and Self-Categorization Theory have been successfully applied to the organizational domain. In this article, the authors provide an overview of these recent developments and present a concept of social identification in organizational contexts, based on these theories. The assumptions of this framework are that (a) social identification in organizational contexts is a multifaceted concept consisting of different dimensions and foci (or targets), (b) higher levels of identification are related to higher productivity and more positive work-related attitudes, and (c) identification is a very flexible concept that is linked to the situational context. The authors present the results of a series of field and laboratory studies in which the proposed relationships are analyzed and, in the main, confirmed. 相似文献

According to the contingent capture hypothesis, observers can specify their control settings in advance of the target’s presentation to quickly attend to relevant target colors. Two predictions were derived from this hypothesis and tested in a manual choice response task. First, contingent capture by color was expected: capture of spatial attention by a better-matching color stimulus should be stronger than capture by a less-matching color stimulus. Second, with the control settings specified in advance, the contingent capture by color should commence early after the stimulus onset and should be evident among fast correct responses in an RT distribution. Both predictions are shown to hold true in two experiments. Results are discussed in light of contrasting evidence for saccadic instead of manual responses. 相似文献

It is assumed that number magnitude comparison is performed by assessing magnitude representation on a single analog mental number line. However, we have observed a unit-decade-compatibility effect in German which is inconsistent with this assumption (Nuerk, Weger, & Willmes, 2001). Incompatible magnitude comparisons in which decade and unit comparisons lead to different responses (e.g., 37_52 for which 3<5, but 7>2) are slower and less accurately responded to than compatible trials in which decade and unit comparisons lead to the same response (e.g., 42_57, for which 4<5 and 2<7). As overall distance was held constant, a single holistic magnitude representation could not account for this compatibility effect. However, because of the inversion property of the corresponding German two-digit number words ("einundzwanzig" ), the language-generality of the effect is questionable. We have therefore examined the compatibility effect with native English speakers. We were able to replicate the compatibility effect using Arabic notation. Thus, the compatibility effect is not language-specific. However, in cross-linguistic analyses language-specific modulations were observed not only for number words but also for Arabic numbers. The constraints imposed on current models by the verbal mediation of Arabic number comparison are discussed. 相似文献

The authors manipulated repetitions and/or changes of abstract response rules and the specific stimulus- response (S-R) associations used under these rules. Experiments 1 and 2, assessing trial-to-trial priming effects, showed that repetition of complete S-R couplings produced only benefits when the rule also repeated (i.e., rule-S-R conjunctions) but costs when identical S-R couplings repeated while rules changed. In Experiments 3 and 4, the authors manipulated amount of experience with specific rule-S-R conjunctions and demonstrated integration between rules and S-R couplings in terms of cumulative practice effects. However, unlike short-term priming effects, cumulative practice supported generalization of experience with specific S-R couplings across rule boundaries (Experiment 4). Results are discussed in terms of constraints on models of hierarchical control and in terms of qualitatively different ways in which people profit from very recent experiences (i.e., all-or-none access to working memory representations) versus cumulative experience (i.e., similarity-based retrieval from long-term memory). 相似文献

Representation facilitates reasoning: what natural frequencies are and what they are not 总被引:4,自引:0,他引:4
A good representation can be crucial for finding the solution to a problem. Gigerenzer and Hoffrage (Psychol. Rev. 102 (1995) 684; Psychol. Rev. 106 (1999) 425) have shown that representations in terms of natural frequencies, rather than conditional probabilities, facilitate the computation of a cause's probability (or frequency) given an effect--a problem that is usually referred to as Bayesian reasoning. They also have shown that normalized frequencies--which are not natural frequencies--do not lead to computational facilitation, and consequently, do not enhance people's performance. Here, we correct two misconceptions propagated in recent work (Cognition 77 (2000) 197; Cognition 78 (2001) 247; Psychol. Rev. 106 (1999) 62; Organ. Behav. Hum. Decision Process. 82 (2000) 217): normalized frequencies have been mistaken for natural frequencies and, as a consequence, "nested sets" and the "subset principle" have been proposed as new explanations. These new terms, however, are nothing more than vague labels for the basic properties of natural frequencies. 相似文献

Question answering requires close attention to the common ground to determine what the questioner wants to know. Because attentiveness to others is more likely to be a self-defining goal when the self is thought of as interdependent with others rather than independent of others, we predicted that self-construal influences attentiveness to the common ground. In Experiment 1, participants' temporary self-construal was manipulated through a priming technique. As predicted, interdependence-primed participants were more likely than independence-primed participants to take the recipient's knowledge into account and avoided providing redundant information in a self-administered questionnaire. Drawing on chronic differences in self-construal, Experiment 2 replicated these findings with participants from independent (Germany) and interdependent (China) cultures. Throughout, participants' differential attentiveness to the common ground resulted in differential question order effects, raising important methodological issues for cross-cultural research. 相似文献

Emotions can be assessed by means of different diagnostic methods, for example, by self-report instruments, ratings of facial expressions, or by projective techniques. This study presents an alternative approach: a computerized investigation of verbally expressed emotions by means of the Affective Dictionary Ulm (ADU; Dahl, H?lzer, & Berry, 1992), which was applied to responses in the Holtzman Inkblot Technique (HIT; Holtzman, 1988; Holtzman, Thorpe, Swartz, & Herron, 1961). A normal group (n = 30), patients with neurotic disorders (n = 30), borderline patients (n = 30), acute schizophrenics (n = 25), and chronic schizophrenics (n = 25) were compared in regard to verbally expressed emotions. According to the results, patients with neurotic disorders did not differ from the normal group in regard to verbally expressed emotions. Borderline patients expressed fear and emotions in general significantly more frequently than all other diagnostic groups. Furthermore, borderline patients differed in regard to specific emotions from patients with neurotic disorders, acute schizophrenics, and chronic schizophrenics. Acute schizophrenics did not differ from the normal group in regard to the expression of emotions, whereas chronic schizophrenics expressed anger, fear, anxiety, and emotions in general significantly less frequently than normals. By a discriminant analysis using verbally expressed emotions as predictors of the diagnosis, hit rates between 87% and 100% could be achieved. Furthermore, hypotheses about correlations between emotions on the one hand and internalized primitive object relations and bizarre-idiosyncratic thinking were tested empirically. Significant correlations could be demonstrated. These results support the validity of assessing emotions through a lexical content analysis of the HIT by use of the ADU. 相似文献
