There is now considerable evidence that human sentence processing is expectation based: As people read a sentence, they use their statistical experience with their language to generate predictions about upcoming syntactic structure. This study examines how sentence processing is affected by readers' uncertainty about those expectations. In a self‐paced reading study, we use lexical subcategorization distributions to factorially manipulate both the strength of expectations and the uncertainty about them. We compare two types of uncertainty: uncertainty about the verb's complement, reflecting the next prediction step; and uncertainty about the full sentence, reflecting an unbounded number of prediction steps. We find that uncertainty about the full structure, but not about the next step, was a significant predictor of processing difficulty: Greater reduction in uncertainty was correlated with increased reading times (RTs). We additionally replicated previously observed effects of expectation violation (surprisal), orthogonal to the effect of uncertainty. This suggests that both surprisal and uncertainty affect human RTs. We discuss the consequences for theories of sentence comprehension.  相似文献

In order to tackle food waste at the prevention stage of the waste hierarchy, an understanding of behaviour that leads to wastage is required. This article examines consumer food waste behaviour in a university setting and the implications for encouraging sharing as a means of mitigating food waste. The embodied and embedded nature of consumption and wasteful behaviours are contended, giving explanation to the transition of food into waste. By undertaking a mixed‐method study and a social media‐based intervention, behaviour that causes food to be wasted within a campus environment is discussed, furthering the current domestic focus of research. The paper argues that consumer food waste behaviour can be better understood by focusing on the practices, routines and habits of consumers given the hidden nature of the food waste issue. A number of barriers are also presented regarding the sharing of food as a means of food waste prevention. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

One of the central tenets of Christian theology is the denial of self for the benefit of another. However, many views on the evolution of altruism presume that natural selection inevitably leads to a self‐seeking human nature and that altruism is merely a façade to cover underlying selfish motives. I argue that human altruism is an emergent characteristic that cannot be reduced to any one particular evolutionary explanation. The evolutionary processes at work in the formation of human nature are not necessarily in conflict with the possibility of altruism; rather, aspects of human nature are uniquely directed toward the care and concern of others. The relationship between altruism, human nature, and evolution can be reimagined by adopting an emergent view of the hierarchy of science and a theological worldview that emphasizes self‐renunciation. The investigation of altruism necessitates an approach that analyzes several aspects of altruistic behavior at different levels in the hierarchy of sciences. This research includes the study of evolutionary adaptations, neurological systems, cognitive functions, behavioral traits, and cultural influences. No one level is able to offer a full explanation, but each piece adds a unique dimension to a much larger puzzle.  相似文献

We conducted a field study to investigate the secondary transfer effect of intergroup contact, consisting in the generalisation of the positive effects of intergroup contact to outgroups uninvolved in the contact situation. Italian secondary school students (N = 175) filled out a questionnaire; the effects of prior contact were statistically controlled. Results showed that contact with immigrants improved attitudes toward them. In turn, these attitudes generalised to attitudes toward two dissimilar outgroups not directly involved in contact: disabled and homosexuals. Notably, we found evidence for a secondary transfer effect of intergroup anxiety and perspective taking, which generalised from immigrants to the disabled and homosexuals. Evidence was found for the mediating role of intergroup attitudes, intergroup anxiety and perspective taking. The theoretical and practical implications of findings are discussed.

Emerging economies by definition tend to be less dependent on expatriate skills and labour than lower-income countries, yet remuneration (pay plus benefits) differences between expatriate and local workers persist in them to some degree. According to relative deprivation theory, economic development paradoxically elevates the salience of relatively small gaps in remuneration. We therefore expected workers to report injustice and demotivation regarding relative remuneration, despite the closing of remuneration gaps between expatriate and local workers due to the economic development of recent years. To explore that possibility, 482 skilled professionals from a variety of sectors and organizations in two emerging economies, India (n = 233, response rate = 54%) and China (n = 249, response rate = 58%), participated in the research. International salaries were greater than local salaries by a factor of 2.73:1 in India and 1.90:1 in China; these mean ratios bordered on intolerable in the India sample and were largely tolerable among the sample from China. In both countries, differently remunerated workers differed in their justice cognitions and their demotivation, with lowered motivation and fewer justice cognitions in the locally salaried, local workers. These differences were however more statistically significant between people working in India than in China. Insofar as the motivational and justice gaps persisted, the findings support relative deprivation theory. Insofar as the same gaps appear to be sharper in the country with the higher-not lower-mean remuneration differential, they do not. An in-country workshop with local experts who interpreted the findings (in India), and content analysis of the participants' recommendations (in China) jointly recommended linking remuneration to (i) workplace performance instead of (ii) economy-of-origin, to help promote (iii) fairness.  相似文献

Abtract: This article argues that the debate between reductive and nonreductive physicalists is best characterized as a disagreement about which properties are natural. Among other things, natural properties are those that characterize the world completely. All physicalists accept the “completeness of physics,” but this claim contains a subtle ambiguity, which results in two conceptions of natural properties. Reductive physicalists should assert, while nonreductive physicalists should deny, that a single set of low‐level physical properties is natural in both of these senses. This way of drawing the distinction succeeds where previous approaches have failed and illuminates why the debate about reductionism is important.  相似文献

This set of studies explored the influence of temporal context across multiple-chain and multiple-successive-encounters procedures. Following training with different temporal contexts, the value of stimuli sharing similar reinforcement schedules was assessed by presenting these stimuli in concurrent probes. The results for the multiple-chain schedule indicate that temporal context does impact the value of a conditioned reinforcer consistent with delay-reduction theory, such that a stimulus signaling a greater reduction in delay until reinforcement has greater value. Further, nonreinforced stimuli that are concurrently presented with the preferred terminal link also have greater value, consistent with value transfer. The effects of context on value for conditions with the multiple-successive-encounters procedure, however, appear to depend on whether the search schedule or alternate handling schedule was manipulated, as well as on whether the tested stimuli were the rich or lean schedules in their components. Overall, the results help delineate the conditions under which temporal context affects conditioned-reinforcement value (acting as a learning variable) and the conditions under which it does not (acting as a performance variable), an issue of relevance to theories of choice.  相似文献

The present study investigated mindfulness‐based stress reduction (MBSR) for young adults with a social anxiety disorder (SAD) in an open trial. Fifty‐three young adults in a higher education setting underwent a standard eight‐week MBSR program. Eight participants (15%) did not complete the program. Participants reported significant reductions in SAD symptoms and global psychological distress, as well as increases in mindfulness, self‐compassion, and self‐esteem. Using intention‐to‐treat (ITT) analyses, effect sizes ranged from large to moderate for SAD symptoms (Cohen's = 0.80) and global psychological distress (= 0.61). Completer analyses yielded large effect sizes for SAD symptoms (= 0.96) and global psychological distress (= 0.81). The largest effect sizes were found for self‐compassion (= 1.49) and mindfulness (= 1.35). Two thirds of the participants who were in the clinical range at pretreatment reported either clinically significant change (37%) or reliable improvement (31%) on SAD symptoms after completing the MBSR program, and almost two thirds reported either clinically significant change (37%) or reliable improvement (26%) on global psychological distress. MBSR may be a beneficial intervention for young adults in higher education with SAD, and there is a need for more research on mindfulness and acceptance‐based interventions for SAD.  相似文献

Although gender equality is a global goal, significant disparity remains between men and women. Benevolent sexism (BS) is widespread and contributes to the maintenance of the gender gap. To reduce BS, many previous studies have implemented long-term intervention programmes. In contrast, we posit that it is necessary to reduce BS efficiently through simpler methods. This study aimed to reduce participants' BS endorsement by presenting experimental vignettes regarding (a) the harm of BS against women and (b) the pervasiveness of BS. An online experiment was conducted with male and female Japanese participants (n = 816). The results showed that the main effect of presenting the harm of BS against women was significant only among female participants. However, neither the main effect of presenting the pervasiveness of BS nor the interaction between presenting harm and pervasiveness were found. We suggested strategies to reduce BS, especially when endorsed by men. Our experimental manipulation can be conducted in a short time and on many participants simultaneously. More empirical studies aimed at reducing BS should be conducted in the future.  相似文献
