Previous studies have found that when low‐status group members are aware that their in‐group is stereotyped as dependent by a specific out‐group (i.e. a dependency meta‐stereotype is salient), they are reluctant to seek help from the high‐status out‐group to avoid confirming the negative meta‐stereotype. However, it is unclear whether low‐status group members would seek more help in the context of a salient dependency meta‐stereotype when there is low (vs. high) group boundary permeability. Therefore, we conducted two experiments to examine the moderating effect of permeability on meta‐stereotype confirmation with a real group. In study 1, we manipulated the salience of the dependency meta‐stereotype, measured participants' perceived permeability and examined their help‐seeking behaviour in a real‐world task. Participants who perceived low permeability sought more help when the meta‐stereotype was salient (vs. not salient), whereas participants who perceived high permeability sought the same amount of help across conditions. In study 2, we manipulated the permeability levels and measured the dependency meta‐stereotype. Participants who endorsed a high‐dependency meta‐stereotype sought more help than participants who endorsed a low‐dependency meta‐stereotype; this effect was particularly strong in the low‐permeability condition. The implications of these results for social mobility and intergroup helping are discussed.  相似文献

A central element of constitutivist accounts of categorical normativity is the claim that the ultimate foundation of the relevant kind of practical authority is sourced in certain tasks, features, and aims that every person inevitably possesses and inescapably has to deal with. We have no choice but to be agents and this fact is responsible for the norms and principles that condition our agency-related activities to have anunconditional normative grip on us. Critics of constitutivism argue that it is exactly because of itsinescapability that agency is a powerless source of normative authority. I investigate why our intuitionsconcerning the appeal to inescapability point into such contrary directions. Why do we feel the attraction ofgrounding categorical normativity in phenomena that not even the skeptic can ignore, on the one hand, butseem to hold dear the principle that “ought implies need not,” on the other? Instead of fully developing thethird, neutral, way of conceptualizing the relationship between inescapability and normativity that theimpasse between constitutivists and their critics suggests, this paper diagnoses the disagreement at hand.That agency is inescapable does neither guarantee nor rule out its status qua source of categoricalnormativity. Both camps of the debate overlook this option and depict their opponents as adhering to animplausible perspective of how appeals to inescapability and unconditional normativity are related. Sincethe debate relies on a false dichotomy it is not surprising that its participants so often talk past each other.  相似文献

Objective: Planning can bridge the gap between intentions and action, but what bridges the gap between planning and action? This study helps to answer the question by disentangling the interrelationships between self-efficacy, planning and preparatory behaviours in predicting physical activity. Preparatory behaviours are tested as a working mechanism of planning. Moreover, it is tested whether the utility of preparatory behaviours depends on an individual’s level of self-efficacy.

Methods: A survey assessed planning, self-efficacy and preparatory behaviours for physical activity. Adults (N = 166) provided data at two measurement points. In a longitudinal model, preparatory behaviours were specified as a mediator between planning and physical activity. Self-efficacy was specified as a possible moderator at two points in the model.

Results: Preparatory behaviours mediated the relationship between planning and physical activity. An interaction between self-efficacy and preparatory behaviours on physical activity was found, indicating that individuals with low self-efficacy beliefs were more active if they engaged more frequently in preparatory behaviours.

Conclusion: Planning seems to stimulate preparatory behaviours, which in turn make future physical activity more likely. Furthermore, as performing preparatory behaviours represent a step forward towards the enactment of behavioural goals, preparatory behaviours may be particular beneficial for individuals afflicted by self-doubts regarding physical activity.  相似文献

Literature assumes that negation is more difficult to understand than affirmation, but this might depend on the pragmatic context. The goal of this paper is to show that pragmatic knowledge modulates the unfolding processing of negation due to the previous activation of the negated situation. To test this, we used the visual world paradigm. In this task, we presented affirmative (e.g., her dad was rich) and negative sentences (e.g., her dad was not poor) while viewing two images of the affirmed and denied entities. The critical sentence in each item was preceded by one of three types of contexts: an inconsistent context (e.g., She supposed that her dad had little savings) that activates the negated situation (a poor man), a consistent context (e.g., She supposed that her dad had enough savings) that activates the actual situation (a rich man), or a neutral context (e.g., her dad lived on the other side of town) that activates neither of the two models previously suggested. The results corroborated our hypothesis. Pragmatics is implicated in the unfolding processing of negation. We found an increase in fixations on the target compared to the baseline for negative sentences at 800?ms in the neutral context, 600?ms in the inconsistent context, and 1450?ms in the consistent context. Thus, when the negated situation has been previously introduced via an inconsistent context, negation is facilitated.  相似文献

In this article we present a training program based on the empirical research conducted in the project 'argumentational integrity'. After a brief sketch of the problem dimensions concerning unfair argumentation we give an overview of the training concept and the underlying empirical research. Exemplification of the instructional design is given for the second and the fifth training dimension (standards of argumentational integrity and reactions to unfair contributions). Finally we indicate how the training is to be evaluated and present initial results demonstrating that in comparison with an untrained control group participants in the training significantly improve their skills in identifying and naming argumentative rule violations.  相似文献

The advantages of assessing self‐perceived deviations of mood states from mood traits in cross‐sectional as well as longitudinal studies are discussed in detail. The validity of self‐perceived mood deviations is analysed in a longitudinal study with three occasions of measurement and 176 participants. In order to assess self‐perceived mood deviations, participants rated the deviation of their momentary mood from how they felt in general with respect to 32 mood adjectives belonging to three mood scales (pleasant–unpleasant, calm–restless, awake–sleepy). Furthermore, mood states, mood traits, and other personality variables (hedonic level, neuroticism, extraversion, openness, agreeableness, conscientiousness) are assessed by self‐report. Using models of latent state–trait theory, it is shown that the self‐perceived mood deviation scales are reliable (reliabilities between 0.73 and 0.95) and sensitive to occasion‐specific fluctuations (occasion specificities between 0.38 and 0.72). The self‐perceived deviation scales show high correlations with latent occasion‐specific deviation variables defined on the basis of repeatedly measured mood states (high convergent validity). In contrast to self‐reported mood states, however, self‐perceived mood deviations show much smaller and in most cases non‐significant correlations with personality variables (high discriminant validity). Furthermore, it is shown that self‐perceived mood deviations can be used to suppress stable situation‐specific variance in mood traits defined as aggregated states. Therefore, it can be demonstrated that including self‐perceived mood deviations in analyses on mood–personality associations enhances the association coefficients considerably. Finally, the implications of the results for the individual assessment of mood deviations, as well as for studies on affect and personality, are discussed.

Model-based calculations indicate that reflex delay and reflex gain are both important for spinal stability. Experimental results demonstrate that chronic low back pain is associated with delayed muscle reflex responses of trunk muscles. The aim of the present study was to analyze the influence of such time-delayed reflexes on the stability using a simple biomechanical model. Additionally, we compared the model-based predictions with experimental data from chronic low back pain patients and healthy controls using surface-electromyography. Linear stability methods were applied to the musculoskeletal model, which was extended with a time-delayed reflex model. Lateral external perturbations were simulated around equilibrium to investigate the effects of reflex delay and gain on the stability of the human lumbar spine. The model simulations predicted that increased reflex delays require a reduction of the reflex gain to avoid spinal instability. The experimental data support this dependence for the investigated abdominal muscles in chronic low back pain patients and healthy control subjects. Reflex time-delay and gain dependence showed that a delayed reflex latency could have relevant influence on spinal stability, if subjects do not adapt their reflex amplitudes. Based on the model and the experimental results, the relationship between muscle reflex response latency and the maximum of the reflex amplitude should be considered for evaluation of (patho) physiological data. We recommend that training procedures should focus on speeding up the delayed reflex response as well as on increasing the amplitude of these reflexes.  相似文献
