Metonymies are exemplary models for complex semantic association processes at the sentence level. We investigated processing of metonymies using event-related functional magnetic resonance imaging (fMRI).During an 1.5 Tesla fMRI scan, 14 healthy subjects (12 female) read 124 short German sentences with either literal (like “Africa is arid”), metonymic (“Africa is hungry”), or nonsense (“Africa is woollen”) content. Sentences were constructed so that they obey certain grammatical, semantic, and plausibility conditions and were matched for word frequency, semantic association, length and syntactic structure. We concentrated on metonymies that were not yet fossilised; we also examined a wide variety of metonymic readings.Reading metonymies relative to literal sentences revealed signal changes in a predominantly left-lateralised fronto-temporal network with maxima in the left and right inferior frontal as well as left middle temporal gyri. Left inferior frontal activation may reflect both inference processes and access to world knowledge during metonymy resolution. 相似文献

The present study examined 7- to 11-month-old infants’ anticipatory and reactive reaching for temporarily occluded objects. Infants were presented with laterally approaching objects that moved at different velocities (10, 20, and 40 cm/s) in different occlusion situations (no-, 20 cm-, and 40 cm-occlusion), resulting in occlusion durations ranging between 0 and 4 s. Results show that except for object velocity and occlusion distance, occlusion duration was a critical constraint for infants’ reaching behaviors. We found that the older infants reached more often, but that an increase in occlusion duration resulted in a decline in reaching frequency that was similar across age groups. Anticipatory reaching declined with increasing occlusion duration, but the adverse effects for longer occlusion durations diminished with age. It is concluded that with increasing age infants are able to retain and use information to guide reaching movements over longer periods of non-visibility, providing support for the graded representation hypothesis (Jonsson &; von Hofsten, 2003) and the two-visual systems model (Milner &; Goodale, 1995). 相似文献

The status-legitimacy hypothesis was tested by analyzing cross-national data about social inequality. Several indicators were used as indexes of social advantage: social class, personal income, and self-position in the social hierarchy. Moreover, inequality and freedom in nations, as indexed by Gini and by the human freedom index, were considered. Results from 36 nations worldwide showed no support for the status-legitimacy hypothesis. The perception that income distribution was fair tended to increase as social advantage increased. Moreover, national context increased the difference between advantaged and disadvantaged people in the perception of social fairness: Contrary to the status-legitimacy hypothesis, disadvantaged people were more likely than advantaged people to perceive income distribution as too large, and this difference increased in nations with greater freedom and equality. The implications for the status-legitimacy hypothesis are discussed. 相似文献

Automatic thoughts as a predictor of internalizing and externalizing problems in Chinese adolescents: A test of the cognitive content‐specificity hypothesis with age effects 下载免费PDF全文

The main aim of the current study was to test the cognitive content‐specificity hypothesis across internalizing and externalizing problems in Chinese adolescents. The participants consisted of 2,158 adolescents aged 11–19 years from three middle schools, and they completed a number of measures assessing a wide range of automatic thoughts and syndromes related to internalizing and externalizing problems. Multivariate regression analyses demonstrated that thoughts about social threats, personal failure and hostility were the strongest predictors of anxiety, depression, and externalizing problems, respectively. Age was a statistically significant, albeit modest, moderator of the relationship between automatic thoughts about social threat and anxiety. The current study provides support for the cognitive content‐specificity hypothesis in internalizing and externalizing problems in a Chinese sample. 相似文献

Reduced autobiographical memory specificity (rAMS) is a characteristic memory bias observed in depression. To corroborate the capture hypothesis in the CaRFAX (capture and rumination, functional avoidance, executive capacity and control) model, we investigated the effects of self-relevant cues and cue valence on rAMS using an adapted Autobiographical Memory Test conducted with a nonclinical population. Hierarchical linear modelling indicated that the main effects of depression and self-relevant cues elicited rAMS. Moreover, the three-way interaction among valence, self-relevance, and depression scores was significant. A simple slope test revealed that dysphoric participants experienced rAMS in response to highly self-relevant positive cues and low self-relevant negative cues. These results partially supported the capture hypothesis in nonclinical dysphoria. It is important to consider cue valence in future studies examining the capture hypothesis. 相似文献

通过3个实验考察语音反应方式下情绪效价对空间Simon效应的影响。实验1采用空间Simon任务范式考察语音反应方式下空间Simon效应的存在;实验2增加刺激的情绪效价维度,采用同样任务考察无关情绪效价对空间Simon效应的影响;实验3在实验2基础上进一步探讨当情绪效价为相关维度时对空间Simon效应的影响。研究结果表明:语音反应方式下,只有当情绪效价为相关维度时,才会对空间Simon效应产生影响,且该影响主要表现在积极效价对认知控制的促进作用而导致空间Simon效应减小或消失,此结果与极性编码一致性假说一致,也拓宽了躯体特异性假说,扩展了以往对情绪影响空间认知的理解。 相似文献

该研究探索了规则的信息量与明显度对规则可获得性的影响。采用改编后的2-4-6任务, 70名大学生参加了两个实验。实验1发现, 规则可获得性除了受到信息量的影响外, 还受到明显度的显著影响; 实验2增加了规则的探测, 发现信息量大、明显度高的规则更容易用语言陈述出来, 而信息量小、明显度低的规则更不容易陈述出来。实验结果启示:信息量大、明显度高的规则可能是一种外显规则, 而信息量小、明显度低的规则可能是一种内隐规则。初步提出了“计算和感知的双加工”模型。 相似文献

The rise in Chinese traders and increased availability of low‐cost imported goods benefits consumers, challenges local African retailers and is a point of tension in local communities. China's presence in Africa has been largely discussed and analysed through a political economy perspective. The social impact in local communities has been documented anecdotally but has yet to be empirically studied. This study took place in Makola Market, Accra, Ghana, to investigate the emerging intergroup encounters between established Ghanaian traders and nascent Chinese traders. Photo‐elicited semi‐structured interviews were conducted to explore how their interrelated experiences shape their interpretative framework and inform the dialectic of contact and social identity. I draw on these interpretative frameworks to propose a new model of contact, the Tri‐relational Contact Model, to capture and highlight how people's experiences include contact relationships with not just each other, but also with their places of business and the goods of trade. The findings from this study empirically highlight the micro‐level impact of China's presence in Ghana and help re‐conceptualize the contact hypothesis through a new model of contact with greater analytical utility to explicate the relational nature of contact and social identity formation.
