In the present study, the authors tested whether an increase in salivation is associated with an increase in subjectively experienced hunger. After conditioning, subjects showed a significant increase in salivation flow. Hunger levels, however, were significantly decreased after conditioning. No correlation was found between salivation flow and hunger levels. It is argued that salivation responses and subjectively experienced hunger are loosely coupled systems. Salivation flow reflects the learning history of a subject which may sometimes be paralleled by a biological state which is called hunger, whereas, at other times, hunger may be absent. The authors conclude that conditioning of preparatory responses such as salivation depends on the probability relationship between exposure to cues (CSs) and food intake (US), as well as the intensity of the US. 相似文献

Conversational rules of everyday communication are applied to the interaction between experimenters and subjects. According to these rules, contributions to a communication should be informative, relevant, true, and unambiguous. It is assumed that subjects determine the pragmatic meaning of instructions and questions on the basis of these rules and the provided context. In contrast to most natural settings, standardized experimental procedures rarely allow for an interactive determination of pragmatic meaning and often preclude feedback as a corrective device. As a consequence, subjects are required to rely heavily on general rules, and even subtle cues may become informationally loaded. The information extracted from context cues may often not be intended by the experimenter. Thus subjects may infer more than they are supposed to, resulting in discrepancies between the experimenter's intended and subjects' inferred meaning of the instructions. If researchers are not sensitive to the information provided by verbal and non-verbal context cues, their interpretation of research results may be based on biased data. Evidence from different research domains is reported to support the presented assumptions and their implications for bias avoiding strategies are discussed. 相似文献

A matching procedure is proposed by which a judge may use the same items in different matches. TheK items in one group most likely to include the correct match with each item in the other are selected. Inclusion of the correct match among theK items chosen is defined as a success. The distribution of the number of successes is discussed. Tables are presented showing the number of successes needed for significance for various values ofK and ofN, the number of items in each group. 相似文献

The test-taking behaviour of some examinees may be so unusual that their test scores cannot be regarded as appropriate measures of their ability. Appropriateness measurement is a model-based approach to the problem of identifying these test scores. The intuitions and basic theory supporting appropriateness measurement are presented together with a critical review of earlier work and a series of interrelated experiments. We conclude that appropriateness measurement techniques are robust to errors in parameter estimation and robust to the presence of unidentified aberrant examinees in the test norming sample. In addition, the frequently criticized ‘three-parameter logistic’ latent trait model was found to be adequate for the detection of spuriously low scores in actual test data. 相似文献

Robert Stalnaker recently proposed a simple theory of propositions using the notion of a set of propositions being consistent, and conjectured that this theory is equivalent to the claim that propositions form a complete atomic Boolean algebra. This paper clarifies and confirms this conjecture. Stalnaker also noted that some of the principles of his theory may be given up, depending on the intended notion of proposition. This paper therefore also investigates weakened constraints on consistency and the corresponding classes of Boolean algebras.

In this genetically informative and longitudinal study of women, we investigated the nature of individual differences in tendencies to depression (TD) and anxiety (TA) as well as in the probability to develop unipolar mood disorders (UMDs), anxiety disorders (ADs) or both. Specifically, we examined the roles of neuroticism, negative and positive life events and their interplay as heritable and environmental factors of variance in TD and TA. Cross‐sectional data from a total of 1200 women including 232 patients (suffering from UMDs and/or ADs) and longitudinal data from 630 female twins including 260 complete pairs were analysed. The analyses yielded that variance in neuroticism mediated the vast majority of the genetic variance in both TD (about 85–90%) and TA (about 70–75%). Negative life events additionally contributed as risk factors accounting for common and specific environmental variance in both TD and TA, whereas positive life events only acted as protective factors in the case of TD. Moreover, TD but not TA was associated with both the probability of exposure and the sensitivity to negative life events and a negative life‐event balance (i.e. more negative than positive experiences). The results were discussed within the framework of additive, dynamic and synergetic diathesis–stress models. Copyright © 2016 European Association of Personality Psychology 相似文献

The present paper re-appraises connectionist attempts to explain how human cognitive development appears to progress through a series of sequential stages. Models of performance on the Piagetian balance scale task are the focus of attention. Limitations of these models are discussed and replications and extensions to the work are provided via the Cascade-Correlation algorithm. An application of multi-group latent class analysis for examining performance of the networks is described and these results reveal fundamental functional characteristics of the networks. Evidence is provided that strongly suggests that the networks are unable to acquire a mastery of torque and, although they do recover certain rules of operation that humans do, they also show a propensity to acquire rules never previously seen. 相似文献

Relationships of gender, age, and education to leadership styles and leaders’ influence tactics were examined with 56 leaders
and 234 followers from a variety of organizations. Leadership behaviors were measured with the Multi-factor Leadership Questionnaire
(MLQ—rater version). Influence tactics were measured with Yukl’s Influence Behavior Questionnaire (IBQ). Multivariate Analysis
of Variance (MANOVA) was used to test behavioral differences attributed to leaders’ gender, age, and education groups, as
well as the interaction of age and education with gender. Results show that gender produced a small direct effect on leadership
behaviors. The interaction of gender and education produced consistent differences in leadership behaviors. Implications for
future research are provided, and a call for re-analysis of previously published work is advised. 相似文献

Understanding the role of leadership aspiration in the under-representation of female leaders is important, because aspiration is a key predictor of hierarchical advancement. A neglected perspective in the relationship between gender and leadership aspiration is the gender of the individual's supervisor. Supervisors can play an important role in providing support and in engendering a sense of control, and both support and control are precursors to leadership aspiration. Yet, supervisors may also act on gender biases that discourage women's leadership aspiration. We argue that there is an interaction between supervisor and subordinate gender such that men experience relatively high levels of support and control regardless of supervisor gender, whereas women experience more support and control and as a result display higher leadership aspiration with a female supervisor. A survey of N = 402 men and women supported these hypotheses regarding the subordinate gender by supervisor gender interactive influence on leadership aspiration, support, control, and the mediated moderation model. 相似文献
