Previous research shows that larger interference is observed in contexts associated with a high proportion of congruent trials than in those associated with a low proportion of congruent trials. Given that one of the most relevant contexts for human beings is social context, researchers have recently explored the possibility that social stimuli could also work as contextual cues for the allocation of attentional control. In fact, it has been shown that individuals use social categories (i.e., men and women) as cues to allocate attentional control. In this work, we go further by showing that individual faces (instead of the social categories they belong to) associated with a high proportion of congruent trials can also lead to larger interference effects compared to individual faces predicting a relatively low proportion of congruent trials. Furthermore, we show that faces associated with a high proportion of congruent trials are more positively evaluated than faces associated with a high proportion of incongruent trials. These results demonstrate that unique human faces are potential contextual cues than can be employed to apply cognitive control when performing an automatic task. 相似文献

ABSTRACTThis paper argues that most prominent normative theories on immigration neglect a critical dimension of the migratory phenomenon, a neglect that blinds them to important rights that, under some circumstances, immigrants ought to have as a matter of justice. Specifically, the paper argues that these theories fail to appreciate that the children of immigrant families, regardless of whether they were born in their parents’ country or in the host country, should benefit from educational rights addressing needs that are particular to their situation. These children may be forced to move between these two countries. This situation generates an obligation for both states (‘receiving’ and ‘sending’) to act jointly to provide educational opportunities so that these children are fully conversant with both cultures and in both languages. Put succinctly, then, we argue that since children of immigrant families lack any certainty of permanent residence in the host society owing to the threat of deportation and the precarity of their legal status, host and home societies bear the duty to offer an education that allows them to be functional in both societies. 相似文献

We report the results of a large-scale picture naming experiment in which we evaluated the potential contribution of nine theoretically relevant factors to naming latencies. The experiment included a large number of items and a large sample of participants. In order to make this experiment as similar as possible to classic picture naming experiments, participants were familiarized with the materials during a training session. Speeded naming latencies were determined by a software key on the basis of the digital recording of the responses. The effects of various variables on these latencies were assessed with multiple regression techniques, using a repeated measures design. The interpretation of the observed effects is discussed in relation to previous studies and current views on lexical access during speech production. 相似文献

Many philosophers and scientists rightly take hallucinations to be phenomena that challenge in a most pressing way our theories
of perception and cognition, and epistemology in general. However, very few challenge the received views on the hallucinatory
experience and even fewer critically delve into the subject with both breadth and depth. There are all kinds of problems concerning
hallucinations—including conceptual, methodological, and empirical issues—that call for a multilevel analysis and an interdisciplinary
approach which in turn provide the detail and scope that the subject demands. In this paper, I present and briefly discuss
four interrelated problems: (1) definitions, (2) dependence on perception, (3) two views on hallucinations, and (4) methodology.
Neglect or underestimation of these problems, among other things, continue to prevent a proper understanding of the concept
and the corresponding experience, giving rise to misconceptions and even plain myths on the subject. Hallucinations do occur;
but in order to productively investigate them (for whatever end), we first need to get clear on the concept and develop a
suitable epistemological framework for their analysis. 相似文献

The study of the cognitive processes in the production of language demands careful selection of stimuli and requires normative databases. The main goal of the present research was to collect normative data for the set of 400 figures taken from Cycowicz, Friedman, Rothstein, and Snodgrass (1997; including the 260 figures of Snodgrass & Vanderwart, 1980) using a sample of native Argentinean Spanish speakers. The pictures have been standardized on the following variables: name agreement, image agreement, familiarity, visual complexity, image variability, age of acquisition, and word association. The obtained norms were compared with the normative data of other studies in Spanish, English, and French. This comparison highlights the variability of some of the measures (e.g., name agreement in naming and verbal association) across the different studies and confirms the necessity of elaborating specific norms that are adapted to the studied population’s linguistic and sociocultural context. The norms described may be downloaded as supplemental materials for this article from http://brm.psychonomic-journals.org/content/supplemental. 相似文献

It remains unclear how memory load affects attentional processes in visual search (VS). No effects, as well as beneficial and detrimental effects of memory load, have been found in this type of task. The main goal of the present research was to explore whether memory load has a modulating effect on VS by means of a different attentional set induced by the order of trials (mixed vs. blocked) and by the time presentation of visual display (long vs. short). In Experiment 1, we randomized the order of type of trial (5, 10 and 15 items presented in the display) while it remained constant (10 items) in Experiments 2A and 2B. In the later experiments, we also changed time presentation of visual display (3000 vs. 1300 ms, respectively). Results showed no differential effects of memory load in Experiments 1 and 2A, but they showed up in Experiment 2B: RTs were longer in the attentional task for trials under high memory load conditions. Although our hypothesis of the attentional set is supported by the results, other theoretical implications are also worth discussing in order to better understand how memory load may modulate attentional processes in VS. 相似文献

Quality is a major current needs and requirements for any university system. The funding that universities receive a relevant influence on the scientific productivity of these. Thus the main objective of this study is to classify the Spanish regions in terms of scientific productivity and economic efficiency of their universities. It followed the same procedure used to prepare the 2009 ranking of research productivity in Spanish universities. The results show that there are differences in the classifications made on the basis of productivity and efficiency in the investigation. The more efficient Spanish regions in managing its resources to obtain research results are Catalonia, Asturias, Aragon, and Cantabria. From the results, each region can compare their situation with the rest and analyze strengths and weaknesses in research in terms of resources. 相似文献
