The effect of different formats on the accuracy of dating news and the distribution of personal events was examined in four conditions. In the first, participants had to date events in the absolute time format (e.g., "July 2004"), and in the second, they had to date events in the relative time format (e.g., "3 weeks ago"). In the other conditions, they were asked to choose between the two formats. We found a small backward telescoping effect for recent news events and a large forward telescoping effect for remote events. Events dated in the absolute time format were more accurate than those dated in the relative time format. Furthermore, participants preferred to date news events with the relative time format and personal events with the absolute time format, as well as preferring to date remote events in the relative time format and recent events in the absolute time format.  相似文献

Large-scale neural network for sentence processing   总被引:4,自引:0,他引:4  
Our model of sentence comprehension includes at least grammatical processes important for structure-building, and executive resources such as working memory that support these grammatical processes. We hypothesized that a core network of brain regions supports grammatical processes, and that additional brain regions are activated depending on the working memory demands associated with processing a particular grammatical feature. We used functional magnetic resonance imaging (fMRI) to test this hypothesis by comparing cortical activation patterns during coherence judgments of sentences with three different syntactic features. We found activation of the ventral portion of left inferior frontal cortex during judgments of violations of each grammatical feature. Increased recruitment of the dorsal portion of left inferior frontal cortex was seen during judgments of violations of specific grammatical features that appear to involve a more prominent working memory component. Left posterolateral temporal cortex and anterior cingulate were also implicated in judging some of the grammatical features. Our observations are consistent with a large-scale neural network for sentence processing that includes a core set of regions for detecting and repairing several different kinds of grammatical features, and additional regions that appear to participate depending on the working memory demands associated with processing a particular grammatical feature.  相似文献

This preliminary study examined the factor structure of the Beliefs About Language Learning Inventory in two samples of about 750 college students of English as a foreign language in Taiwan. Results of confirmatory factor analysis lend partial support to Horwitz's theoretical five-factor belief model. Subsequent exploratory and confirmatory factor analyses of data show that a four-factor model represented by only 12 items performed better than other models both theoretically and empirically. This model consists of two dimensions already theorized in the inventory: Difficulty of Language Learning and Foreign Language Aptitude, and two newly interpreted dimensions, Importance of Spoken Language and Analytical Approaches to Language Learning. Although this four-factor model could be replicated in an independent sample, the factors are not reliable, suggesting the need to search for a more representative set of beliefs to tap specific aspects of language learning.  相似文献

ABSTRACT

Near-death experiences (NDEs) are usually associated with positive affect, however, a small proportion are considered distressing. We aimed to look into the proportion of distressing NDEs in a sample of NDE narratives, categorise distressing narratives according to Greyson and Bush’s classification (inverse, void or hellish), and compare distressing and “classical” NDEs. Participants wrote down their experience, completed the Memory Characteristics Questionnaire (assessing the phenomenology of memories) and the Greyson scale (characterising content of NDEs). The proportion of suicidal attempts, content and intensity of distressing and classical NDEs were compared using frequentist and Bayesian statistics. Distressing NDEs represent 14% of our sample (n?=?123). We identified 8 inverse, 8 hellish and 1 void accounts. The proportion of suicide survivors is higher in distressing NDEs as compared to classical ones. Finally, memories of distressing NDEs appear as phenomenologically detailed as classical ones. Distressing NDEs deserve careful consideration to ensure their integration into experiencers’ identity.  相似文献

Abstract

Critical social theories look critically at the ways in which particular social arrangements hinder human flourishing, with a view to bringing about social change for the better. In this they are guided by the idea of a good society in which the identified social impediments to human flourishing would once and for all have been removed. The question of how these guiding ideas of the good life can be justified as valid across socio‐cultural contexts and historical epochs is the most fundamental difficulty facing critical social theories today. This problem of justification, which can be traced back to certain key shifts in the modern Western social imaginary, calls on contemporary theories to negotiate the tensions between the idea of context‐transcendent validity and their own anti‐authoritarian impulses. Habermas makes an important contribution towards resolving the problem, but takes a number of wrong turnings.  相似文献

Abstract

We examined the role of experience in affordance perception for low crawling with altered body dimensions under barriers of different heights. Adults decided which of five backpacks (10–30?cm thick) they would be able to wear while low crawling under barriers. Participants were assigned to one of three experience conditions. Participants in the Pre/Post-choice experience condition crawled under the barrier before and after picking a backpack, participants in the Feedback condition crawled under the barrier after picking a backpack, but participants in the No Experience condition received no low-crawling experience. Past research suggests that pre-choice experience with low crawling under the barrier would lead to more accurate responses. Overall, participants in all three conditions scaled the height of the backpack to the barrier height. Pre-choice low-crawling experience strongly influenced backpack choices such that participants in the Pre/Post condition picked significantly smaller backpacks and produced fewer failures than participants in the other conditions. The results provide evidence that brief practice, in an unfamiliar posture, can lead to improvements in affordance perception.  相似文献

We aimed to identify the effect of state-anger on precision, speed, and power components of performance during fencing attacks. We conducted a laboratory-based, single-case research experiment to test the fine motor task performance of two experienced and two elite-level fencers under two emotional states: anger and emotion-neutral. We assessed anger via psychophysiological and self-report measures, and we induced anger via a brief imagery intervention. Through the use of an innovative design, which included multiple measures of change, we showed that anger had a consistent negative effect on precision but an inconsistent relationship with response time and muscle activity. The current research design and protocol offer a novel and in-depth method for examining the specific relationships between affective states, emotions, and the complexities that underpin performance. The specific effects of anger on performance were multifarious, complex, and inconsistent. Nonetheless, the results tend to indicate that anger facilitates reaction time and debilitates performance, and these effects were clearer for the most elite performers. The effects of anger on performance are clearly complex, so it would be rather premature to make any suggestions for future practice at this point. Nonetheless, the clearer findings with the elite fencers indicate that researchers will likely yield the most fruitful insights by examining the effects of emotion of performance in elite performers.  相似文献

A considerable amount of research has demonstrated the value of imagined contact in reducing social prejudice. The current study investigated the efficacy of imagined intergroup contact in improving attitudes towards male homosexuals on both explicit and implicit measures. Eighty-five heterosexual undergraduate students were randomly allocated to one of three conditions: imagined interaction, prime control or unrelated imagery control. Overall, no significant differences were found between the imagery conditions for either the explicit or implicit attitude measures, even when controlling for prior contact. Accordingly, the present findings, unlike those of Turner et al. (Journal of Personality and Social Psychology 93: 369–388, 2007b) and (Group Processes & Intergroup Relations 10: 427–441, 2007a), do not offer support for the effectiveness of indirect contact in reducing prejudice toward male homosexuals. Some explanations for the inconsistency of findings are discussed.  相似文献

Evolutionary psychology has been proposed as a metatheoretical framework for psychology. We argue that evolutionary psychology should be expanded if it is to offer new insights regarding the major issues in psychology. Evolutionary developmental biology can provide valuable new insights into issues such as the domain-specificity of the human mind, the nature–nurture debate, stages in development, and the origin of individual differences. Evolutionary developmental biology provides evidence for the hypotheses that domain-general and domain-specific abilities co-occur, that nature and nurture interact in a dynamic and nonadditive way, that stages occur in development, and that individual differences are the result of pleiotropic effects during development.  相似文献
