We used several cue–target SOAs (100, 500, 1000 ms) and three different degrees of cue predictability (Non-predictive-50%, Predictive-75%, Counter-predictive-25%), to investigate the role of awareness of cue–target predictability on cueing effects. A group of participants received instructions about the informative value of the cue, while another group did not receive such instructions. Participants were able to extract the predictive value of a spatially peripheral cue and use it to orient attention, whether or not specific instructions about the predictive value of the cue were given, and no matter their ability to correctly report it in a post-test questionnaire. In the non-predictive block, bad estimators who received no instructions showed regular cueing effects, while good estimators exhibited smaller and non-significant facilitatory effects at the short SOA and an absence of significant IOR at longer SOAs. However, for the instructions group, the pattern of results reversed. 相似文献

Variation in intracellular calcium concentration regulates the induction of long-term synaptic plasticity and is associated with a variety of memory/retrieval and learning paradigms. Accordingly, impaired calcium mobilization from internal deposits affects synaptic plasticity and cognition in the aged brain. During taste memory formation several proteins are modulated directly or indirectly by calcium, and recent evidence suggests the importance of calcium buffering and the role of intracellular calcium deposits during cognitive processes. Thus, the main goal of this research was to study the consequence of hampering changes in cytoplasmic calcium and inhibiting SERCA activity by BAPTA-AM and thapsigargin treatments, respectively, in the insular cortex during different stages of taste memory formation. Using conditioned taste aversion (CTA), we found differential effects of BAPTA-AM and thapsigargin infusions before and after gustatory stimulation, as well as during taste aversive memory consolidation; BAPTA-AM, but not thapsigargin, attenuates acquisition and/or consolidation of CTA, but neither compound affects taste aversive memory retrieval. These results point to the importance of intracellular calcium dynamics in the insular cortex during different stages of taste aversive memory formation. 相似文献

We tested how anticipated emotions interact with personal experience in risk behavior to improve predictions from TPB on behavioral intention (BI) and behavioral expectation (BE) for sex without condom (Study 1) and excessive drinking (Study 2). In the moderate-high experience group, anticipated emotional profiles (AEPs) improve TPB prediction from 28% to 45% in the case of BI and from 19% to 40% in that of BE in relation to sexual risk behavior (Study 1), and from 23% to 36% in the case of BI and from 17% to 31% in that of BE in relation to binge drinking (Study 2). However, in the low-experience group (Study 2) AEPs improve TPB predictions for BI (12% to 34%) but not for BE, showing that in less experienced people BI and BE are not equivalent: anticipated emotions have different relevance in their prediction. These results were replicated using a general negative anticipated emotion index (averaging emotional categories). 相似文献

Spain is one of the EU countries that receive most immigrants, especially from Latin America. The process of migration implies a high level of stress what may have repercussions for the mental health of immigrants. The purposes of this study were: (a) to determine whether the degree of mental health of immigrant women differs according to their rural or urban origin, (b) to compare the mental health of immigrant women with that of the female normative sample of host population (Spain). A sample of 186 Latin American immigrant women (142 from urban areas and 44 from rural areas) was recruited in Barcelona by means of a consecutive case method. A structured interview and the SCL-90-R were administered. The results indicated that the immigrant women from rural origin reported higher levels of psychological symptomatology than those from urban areas. Immigrants reported higher levels of psychological symptomatology than the native female population and in most of the psychological symptoms exceeded 90% of the native Spanish population. Migration is a powerful stressor which may lead to psychological distress. Being female of rural origin and being in an illegal situation is related with an increase in symptomatology. 相似文献

Earlier studies have demonstrated that spatial cueing differentially reduces stimulus-stimulus congruency (e.g., spatial Stroop) interference but not stimulus-response congruency (e.g., Simon; e.g., Lupiá?ez & Funes, 2005). This spatial cueing modulation over spatial Stroop seems to be entirely attributable to object-based attention (e.g., Luo, Lupiá?ez, Funes, & Fu, 2010). In the present study, two experiments were conducted to further explore whether the cueing modulation of spatial Stroop is object based and/or space based and to analyse the "locus" of this modulation. In Experiment 1, we found that the cueing modulation over spatial Stroop is entirely object based, independent of stimulus-response congruency. In Experiment 2, we observed that the modulation of object-based attention over the spatial Stroop only occurred at a short cue-target interval (i.e., stimulus onset asynchrony; SOA), whereas the stimulus-response congruency effect was not modulated either by object-based or by location-based attentional cueing. The overall pattern of results suggests that the spatial cueing modulation over spatial Stroop arises from object-based attention and occurs at the perceptual stage of processing. 相似文献

Attention has often been considered to be a gateway to consciousness (Posner, Proceedings of the National Academy of Sciences of the United States of America, 91(16), 7398–7403, 1994). However, its relationship with conscious perception (CP) remains highly controversial. While theoretical models and experimental data support the role of attention in CP (Chica, Lasaponara, Lupiáñez, Doricchi, &; Bartolomeo, NeuroImage, 51, 1205–1212, 2010; Dehaene, Changeux, Naccache, Sackur, &; Sergent, Trends in Cognitive Sciences, 10, 204–211, 2006; Mack &; Rock, Inattentional blindness, 1998), recent studies have claimed that at least some forms of attention—endogenous or top-down spatial attention—are neither sufficient nor necessary for CP (Koch &; Tsuchiya, Trends in Cognitive Sciences, 11, 16–22, 2007). In the present experiments, we demonstrate the importance of exogenously triggered attention for the modulation of CP. Weak or null effects were instead observed when attention was triggered endogenously. Our data are discussed in the framework of recent neuropsychological models (Dehaene et al., Trends in Cognitive Sciences, 10, 204–211, 2006), postulating that activity within reverberating frontoparietal networks, as colocalized with spatial--orienting systems, is the brain correlate of consciously processed information. 相似文献

The present paper focuses on the role of animacy in the processing of relative clauses (RCs) after complex NPs. We follow research by the Desmet et al. team on Dutch in exploring the role of animacy in Spanish RCs. We present data from a corpus study and two self-paced experiments and we compare the three studies and the Dutch and Spanish results. Our main objective is to fill important gaps in past research on the processing of adjunction ties in Spanish and to offer a more detailed exploration of grain effects in exposure-based accounts. In particular, we have sought both to analyse the match between corpus studies and online processing in Spanish much more closely than it has been until now and to see whether animacy could revert the well-established tendency of Spanish RCs to attach high inside the complex noun phrase. 相似文献

Conclusion I am pleased to have been able to vindicate Plato from the oft-rehearsed charge of not having distinguished relations from qualities. Not only does Phaedo 102B7-C4 show quite clearly that he did make the proper distinction, but the theory of relations he adumbrated there is logically sound and ontologically viable. Furthermore, it is refreshing to think of relations not as Forms or universals, but as chains of ontologically tied universals.Naturally, now that we have a clear understanding of Plato's Phaedo theory of relations and relational facts there is plenty of work to do. We must examine the other dialogues for alterations or even preservation of that theory. Moreover, there are those arguments of Aristotle that purport to reduce Plato's Theory of Forms to absurdity on account of relations. But of this I shall say more at some other time. 相似文献

People can generate the same thoughts or process the same information with different degrees of ease, and this subjective experience has implications for attitudes and social judgment. In prior research, it has generally been assumed that the experience of ease or fluency is interpreted by people as something good. In the two experiments reported here, the meaning or value of ease was directly manipulated, and the implications for evaluative judgments were explored. Across experiments, we replicated the traditional ease-of-retrieval effect (more thought-congruent attitudes when thoughts were easy rather than difficult to generate) when ease was described as positive, but we reversed this effect when ease was described as negative. These findings suggest that it is important to consider both the content of metacognition (e.g., "those thoughts were easy to generate") and the value associated with that content (e.g., "ease is good" or "ease is bad"). 相似文献
