In the present study, we examined letter detection in very frequent function-word sequences. It has been claimed that such sequences are processed in a unitized manner, thus preempting access to their constituent letters. In contrast, we showed that letter detection in the words for and the (1) was no more difficult when the words appeared in adjacent locations in a sentence (familiar) than when they appeared apart (less familiar sequence) and (2) was contingent upon the words' syntactic roles within the phrase. Thus, letter detection in for was easier when the sequence was separated by a clause boundary than when the words were part of the same clause. The advantage derived from clause separation was strongest when a comma divided clauses. These results challenge the unitization account of the "missing-letter" effect in common phrases and support a position where this phenomenon is seen to reflect the extraction of phrase structure during reading.  相似文献

In this essay we develop and argue for the adoption of a more comprehensive model of research ethics than is included within current conceptions of responsible conduct of research (RCR). We argue that our model, which we label the ethical dimensions of scientific research (EDSR), is a more comprehensive approach to encouraging ethically responsible scientific research compared to the currently typically adopted approach in RCR training. This essay focuses on developing a pedagogical approach that enables scientists to better understand and appreciate one important component of this model, what we call intrinsic ethics. Intrinsic ethical issues arise when values and ethical assumptions are embedded within scientific findings and analytical methods. Through a close examination of a case study and its application in teaching, namely, evaluation of climate change integrated assessment models, this paper develops a method and case for including intrinsic ethics within research ethics training to provide scientists with a comprehensive understanding and appreciation of the critical role of values and ethical choices in the production of research outcomes.  相似文献

This paper develops a classical model for our ordinary use of the truth predicate (1) that is able to address the liar's paradox and (2) that satisfies a very strong version of deflationism. Since the model is a classical in the sense that it has no truth value gaps, the model is able to address Tarski's indictment of our ordinary use of the predicate as inconsistent. Moreover, since it is able to address the liar's paradox, it responds to arguments against deflationism based upon that paradox alone. The model is based upon a notion of the complexity of propositions that a fixed set of speakers might express. A context-sensitive definition of the truth predicate is then provided based upon a class of possible worlds defined in terms of these speakers. Reasonable constraints on the memories and lifetimes of ordinary speakers are used to limit the set of propositions that they might express so that deflationist requirements are satisfied.  相似文献

Volitional action and self-control—feelings of acting according to one’s own intentions and in being control of one’s own actions—are fundamental aspects of human conscious experience. However, it is unknown whether high-level cognitive control mechanisms are affected by socially salient but nonconscious emotional cues. In this study, we manipulated free choice decisions to act or withhold an action by subliminally presenting emotional faces: In a novel version of the Go/NoGo paradigm, participants made speeded button-press responses to Go targets, withheld responses to NoGo targets, and made spontaneous, free choices to execute or withhold the response for Choice targets. Before each target, we presented emotional faces, backwards masked to render them nonconscious. In Intentional trials, subliminal angry faces made participants more likely to voluntarily withhold the action, whereas fearful and happy faces had no effects. In a second experiment, the faces were made supraliminal, which eliminated the effects of angry faces on volitional choices. A third experiment measured neural correlates of the effects of subliminal angry faces on intentional choice using EEG. After replicating the behavioural results found in Experiment 1, we identified a frontal-midline theta component—associated with cognitive control processes—which is present for volitional decisions, and is modulated by subliminal angry faces. This suggests a mechanism whereby subliminally presented “threat” stimuli affect conscious control processes. In summary, nonconscious perception of angry faces increases choices to inhibit, and subliminal influences on volitional action are deep seated and ecologically embedded.  相似文献

Depression is associated with increased HIV morbidity and mortality, particularly among African-American women (AAW) in the United States. The purpose of this qualitative study was to explore religious practices, spiritual beliefs, and experiences among AAW with co-occurring HIV infection and depression. A transcendental phenomenological study design was used to explore the experiences of AAW's religion and spirituality after an HIV diagnosis and living with depression. The four themes that were identified included: Religious Conflict and Return to Religious Practices; Religious Fortitude Broken and Feeling Judged; Spiritual Connection is More Powerful than Attending Church Services; and Spiritual Healing and Re-Connecting with Spirituality. These findings suggest that the distinction between internal and external manifestations of spirituality is important and that given the current religious climate, interventions that focus on supporting internal spiritual practice may be a more important and effective approach for AAW with co-occurring HIV infection and depression.  相似文献

The present study investigated the relative roles of identity structure (i.e., personal identity) and identity contents (i.e., religious identity and moral identity) in predicting emerging adults’ prosocial and antisocial behaviors. The sample included 9,495 college students. A variable-centered analysis (path analysis) used personal identity, religious identity, and moral identity as predictors of prosocial and antisocial behavior and tested interactions of personal identity with religious identity and moral identity. Moral identity was the strongest predictor of both behaviors, and religious identity and moral identity both interacted with personal identity in predicting antisocial behavior. A person-centered analysis (latent profile analysis) found three classes: integrated, moral identity–focused, and religious identity–focused, with integrated being most adaptive on both outcomes.  相似文献
