Recent research on brain activity suggests that visual attention increases in response to emotional images. This increase is reflected in signs of greater activity, in response to different emotional visual stimuli, in parietal and parietooccipital areas in several studies employing neuroimaging techniques and event-related potentials (ERPs). In the latter case, greater parietal and parietooccipital negativities have been observed. The objective of the present study was to examine the role of a person's level of motivation towards the emotional stimulus with respect to this ERP pattern. Two groups of stimuli were presented to 60 participants: neutral or N (photographs of taps) and appetitive or A (photographs of cakes). The level of hunger was measured via a questionnaire. Recordings were taken at PO3, PO4, P7, and P8. The largest differences, as a function of appetite, were produced between 575 and 625 ms. Multiple regression analyses were carried out to study the relationship between subjects' appetite and their ERP recordings in response to A and N stimuli. There was a significant negative association between appetite and 575–625 mean amplitude in response to stimulus A at PO3 and PO4. 相似文献

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation. 相似文献

Workplace incivility is a growing problem in nursing. However, most studies that explore this psychosocial risk and its consequences do so considering a single level and a between‐person perspective. The aims of the study were to explore whether the effects of experiencing incivility during work‐time could explain the daily levels of well‐being of nurses at home; and to analyze if that relationship could be moderated by their levels of emotional dysregulation as a trait. This is a multilevel study with diary methodology. The study was carried out in 18 primary health‐care centers belonging to Madrid and the Basque Country, in Spain. Ninety‐four nurses completed a general questionnaire and 54 of them a diary booklet over five consecutive working days in two different moments, immediately after work and at bedtime. The results showed that nurses’ emotional dysregulation moderated the relationship between daily workplace incivility and daily fatigue, and positive affect at night at home. However, there were no direct effects of daily incivility on these outcome variables. In conclusion, the presence of difficulties in emotional regulation among nurses can increase the negative effects of daily workplace incivility on their health and well‐being. 相似文献

This study analyzed the relationship between terrorist threat and discrimination, operationalized by support for retributive justice against Islamic groups suspect of terrorist crimes. Two experimental studies were performed. Study 1 (N = 215) showed that the terrorist threat against the ingroup raises the support for the retributive procedures through the dehumanization of the outgroup. Study 2 (N = 304) analyzed how the mediating role of dehumanization in the relationship between terrorist threat and support for retributive justice is moderated by right‐wing authoritarianism (RWA). In addition, the study aimed to verify if the dehumanization of outgroup and RWA could explain the relationship between terrorist threat and discrimination of Muslim immigrants. The results indicated that adherence to RWA favors dehumanization of the outgroup and, consecutively, the discrimination, operationalized as support for the use of retributive justice. The adherence to RWA has been identified as the mechanism that explains the discrimination against Muslim immigrants. 相似文献

The vocabulary spurt predicts the emergence of backward semantic inhibition in 18‐month‐old toddlers
The current study examines the relationship between 18‐month‐old toddlers’ vocabulary size and their ability to inhibit attention to no‐longer relevant information using the backward semantic inhibition paradigm. When adults switch attention from one semantic category to another, the former and no‐longer‐relevant semantic category becomes inhibited, and subsequent attention to an item that belongs to the inhibited semantic category is impaired. Here we demonstrate that 18‐month‐olds can inhibit attention to no‐longer relevant semantic categories, but only if they have a relatively large vocabulary. These findings suggest that an increased number of items (word knowledge) in the toddler lexical‐semantic system during the “vocabulary spurt” at 18‐months may be an important driving force behind the emergence of a semantic inhibitory mechanism. Possessing more words in the mental lexicon likely results in the formation of inhibitory links between words, which allow toddlers to select and deselect words and concepts more efficiently. Our findings highlight the role of vocabulary growth in the development of inhibitory processes in the emerging lexical‐semantic system. 相似文献

The lottery problem is the problem of explaining why mere reflection on the long odds that one will lose the lottery does not yield knowledge that one will lose. More generally, it is the problem of explaining why true beliefs merely formed on the basis of statistical evidence do not amount to knowledge. Some have thought that the lottery problem can be solved by appeal to a violation of the safety principle for knowledge, i.e., the principle that if S knows that p, not easily would S have believed that p without p being the case. Against the standard safety‐based solution, I argue that understanding safe belief as belief that directly covaries with the truth of what is believed in a suitably defined set of possible worlds forces safety theorists to make a series of theoretical choices that ultimately prevent a satisfactory solution to the problem. In this way, I analyze several safety principles that result from such choices—the paper thus gives valuable insights into the nature of safety—and explain why none solves the lottery problem, including their inability to explain away Gettierized lottery cases. On a more positive note, I show that there is a viable solution in terms of safety if we get rid of the unquestioned assumption that safe beliefs directly track the truth. The alternative is a conception of safe belief according to which what safe beliefs directly track is the appropriateness of the circumstances and, indirectly, the truth. The resulting safety principle, I argue, explains why mere statistical evidence is not a safe source of knowledge. 相似文献
