In 4 studies, the authors examined the impact of categorization on the recollection of ethnically ambiguous faces. Participants were presented with faces lying at various locations on mixed-race continua (i.e., Caucasian-North African and Caucasian-Asian faces were used as source images in a morphing program). In all studies, the prevalence of exclusive ethnic features in a face distorted participants' recollections of the face toward faces more typical of the category. Specifically, the recollection of 30% North African (or 30% Asian) faces shifted toward Caucasian source faces, whereas the recollection of 70% North African (or 70% Asian) faces shifted toward North African (Asian) source faces. Memory distortions did not emerge for extremely ambiguous (50%) faces and proved larger on mixed-race than same-race continua (Studies 3 and 4). Memory distortions also emerged with high levels of confidence. The authors elaborate on the theoretical and practical implications of these findings. 相似文献

Recent models of lexical processing suggest that written spelling partly depends upon the semantic system. According to these models, a deterioration in word meanings would necessarily lead to a spelling impairment, especially for low-frequency and orthographically irregular words. We report a case study of a patient (MK) with semantic dementia who presents impairments in knowledge of word meanings and surface dysgraphia. By specifically identifying concepts that are still known or that are partially or completely deteriorated, we show that the patient's spelling deficit is highly correlated with word comprehension. These data confirm that surface dysgraphia is directly linked to the breakdown in semantic memory. 相似文献

Fluctuations in pupil size have been shown to reflect variations in processing demands during lexical and syntactic processing in language comprehension. An issue that has not received attention is whether pupil size also varies due to pragmatic manipulations. In two pupillometry experiments, we investigated whether pupil diameter was sensitive to increased processing demands as a result of comprehending an indirect request versus a direct statement. Adult participants were presented with 120 picture–sentence combinations that could be interpreted either as an indirect request (a picture of a window with the sentence “it's very hot here”) or as a statement (a picture of a window with the sentence “it's very nice here”). Based on the hypothesis that understanding indirect utterances requires additional inferences to be made on the part of the listener, we predicted a larger pupil diameter for indirect requests than statements. The results of both experiments are consistent with this expectation. We suggest that the increase in pupil size reflects additional processing demands for the comprehension of indirect requests as compared to statements. This research demonstrates the usefulness of pupillometry as a tool for experimental research in pragmatics. 相似文献

Twinning projects between immigrants and local residents are often analyzed from the viewpoint of intercultural relations
or adaptation to the host society. Our concern here is with the domestic processes at work in twinning projects implemented
by community organizations and funded by the Ministère des Relations avec les Citoyens et de l'Immigration. This draws from
a research project carried out among seventy-five twinned families, half of which are Quebecois and half immigrants of diverse
origins. Our analysis centers around the different forms of appropriation open to actors: volunteer work, intervention, and
mutual aid. 相似文献

It has been suggested that word- and face recognition rely on a common cerebral network for perceptual processing. To further explore this hypothesis, face- and word recognition were assessed in seven patients with focal lesions after stroke of the posterior cerebral artery in either hemisphere. The aim was to investigate if problems in face- and word recognition would co-occur, if testing was sensitive and patients were not pre-selected based on behavioural symptoms. Patients and matched controls were given a reading test and a delayed matching paradigm with faces, objects, and words. Interestingly, all patients with word recognition difficulties had problems in face recognition, independently of the affected hemisphere, supporting the existence of a bilateral perceptual network for faces and words. However, two patients showed selective face recognition problems after unilateral damage to either hemisphere, suggesting that parts of this network may be more critical for face than for word recognition. 相似文献
