The human sense of fairness entails sensitivity not just to equality, the equal division of resources, but also to merit, the relationship between an individual’s share of resources and how hard they worked for their share. Recent evidence suggests that our sensitivity to equality has deep phylogenetic roots: several nonhuman animal species show an aversion to unequal reward distributions. However, the extent to which nonhuman animals share sensitivity to merit remains poorly understood, largely because previous studies have failed to properly manipulate work effort in inequity aversion tasks. Here, we tested whether cotton-top tamarins (Saguinus oedipus) would exhibit a differential response to inequity when acquiring rewards was either (1) effortful or (2) effortless. Subjects engaged in a pulling task in which they had an opportunity to deliver a disadvantageously unequal distribution of food to themselves and a partner (one piece for self, four pieces for partner). We made delivery effortful by adding a weight to the pulling handle. Critically, effort was calibrated to each individual. Results show that individuals varied markedly in their response to effort, highlighting the importance of manipulating work effort at the individual level. Overall, subjects showed little aversion to inequity. However, subjects were slightly less likely to accept inequity when doing so was effortful, although this effect was pronounced in only one individual. Our findings suggest a new method for capturing individual variation in effort and for studying the roots of the concept of merit in nonhuman animals. 相似文献

In this article I ask how fruitful the concept of alienation can be for thinking critically about the nature and causes of the contemporary environmental crisis. The concept of alienation enables us to claim that modern human beings have become alienated or estranged from nature and need to become reconciled with it. Yet reconciliation has often been understood—notably by Hegel and Marx—as the state of being ‘at-home-with-oneself-in-the-world’, in the name of which we are entitled, perhaps even obliged, to overcome anything in nature that is alien to the human mind. This approach to alienation derives ultimately from the German Idealist philosopher J. G. Fichte. I explore an alternative conception of alienation and reconciliation to be found in the work of the Early German Romantics, especially Friedrich Schlegel and Novalis. The Romantics think of reconciliation as including a dimension of alienation, in the form of an awareness that nature is greater than and exceeds the understanding of human beings, insofar as we are merely limited parts of the all-encompassing whole that is nature. I argue that this is a more fruitful approach to alienation and reconciliation than that pursued by Fichte, Hegel, and Marx. 相似文献

Traditional approaches to measurement of violations of academic integrity may overestimate the magnitude and severity of cheating and confound panic with planned cheating. Differences in the severity and level of premeditation of academic integrity violations have largely been unexamined. Results of a study based on a combined sample of business students showed that students are more likely to commit minor cheating offenses and engage in panic-based cheating as compared to serious and planned cheating offenses. Results also indicated there is a significant interaction between severity and type (planned vs. panic) of cheating. We hypothesized serious and planned cheating offenses would be related to justifications and found the largest differences were between panic and planned. Finally, panic and minor cheating were associated with two self-control-related personality traits. Implications for cheating research are discussed. 相似文献

Cognitive deficits are among the most important factors leading to poor functional outcomes in schizophrenia, with deficits in declarative memory among the largest and most robust of these. Thus far, attempts to enhance cognition in schizophrenia have shown only modest success, which underlies increasing efforts to develop effective treatment strategies. This review is divided into three main parts. The first section delineates the nature and extent of the deficits in both patients with schizophrenia and in their adult, non-psychotic relatives. The second part focuses on structural and functional abnormalities in the hippocampus, both in people with schizophrenia and in animal studies that model relevant features of the illness. The third section views problems in declarative memory and hippocampal function from the perspective of elevated rates of common medical disorders in schizophrenia, with a focus on insulin insensitivity/diabetes. The likelihood that poor glucose regulation/availability contribute to declarative memory deficits and hippocampal abnormalities is considered, along with the possibility that schizophrenia and poor glucose regulation share common etiologic elements, and with clinical implications of this perspective for enhancing declarative memory. 相似文献

An implicit theory of ability approach to motivation argues that students who believe traits to be malleable (incremental
theorists), relative to those who believe traits to be fixed (entity theorists), cope more effectively when academic challenges
arise. In the current work, we integrated the implicit theory literature with research on top dog and underdog status to predict
self-efficacy in an academic context. To examine our predictions, we assessed college students’ (N = 165) implicit theories of mathematical ability and manipulated their underdog versus top dog status in a math competition.
We hypothesized that holding an incremental (vs. entity) theory would interact with competition status (underdog vs. top dog)
to predict mathematical self-efficacy. When in an underdog position, incremental (vs. entity) theories boosted students’ mathematical
self-efficacy. Moreover, a mediated moderation model revealed that the experience of less helplessness accounted for greater
self-efficacy in mathematical ability among academic underdogs with incremental (vs. entity) theories. Implications for teaching
practices are discussed. 相似文献

The shading information in images that depict surfaces of 3-D objects cannot be perceived correctly unless the direction of the illuminating light source is known and, in the absence of this knowledge, perception in adults is consistent with a light-from-above Bayesian prior assumption. In order to investigate if children make use of a similar assumption, 171 children between the ages of 4.6 and 10.8 years were tested with 20 images containing shading information, where the shape depicted in each image could be perceived as either convex or concave. Each child's Bayesian prior probability that light comes from above was estimated, and (assuming that decision-noise is approximately the same in all children) regression analyses revealed a significant increase in this prior probability of 0.034-0.035 per year, and predict a neutral prior (0.5) at 1.6 years for naturalistic picture stimuli and 3.6 years for abstract symbol stimuli. Additionally, each child's prior probability for perceiving shapes as being convex/concave was estimated, and was found to be close to a neutral value of 0.5 for all ages. Together, these results indicate that children have a neutral prior for shape convexity, and that their prior probability for lighting direction gradually shifts towards an adult-like prior value as they grow older. Finally, the status of these one-dimensional priors is discussed in relation to marginal distributions of high-dimensional priors implicit in the statistical structure of the physical word. 相似文献

This study investigates the early manifestation of co-occurring depression and conduct problems as a predictor of heightened risk for later suicidal ideation and behavior in a community sample of 521 adolescents. Self-reported symptoms of depression and conduct problems were evaluated in early 6th grade. Suicidal thoughts and behaviors were tracked through multiple assessments carried out over the middle school years. Compared to adolescents with depression symptoms only, conduct problem symptoms only, or low psychopathology, those with co-occurring depression and conduct problem symptoms had the highest risk for subsequent suicidal ideation, recurrent suicidal behaviors, and suicide attempts. 相似文献

Research indicating that decision makers often distort new information to favor nascent preferences has focused primarily on riskless choice rather than risky choice. In addition, the critical assumption that information distortion mediates the link between the initially preferred alternative and the final choice has not been tested in a compelling manner. In an experiment designed to fill these gaps, participants made six choices involving pairs of hypothetical three‐outcome monetary gambles. We manipulated initial preferences by varying the order in which gamble features were presented. Multilevel regressions indicated that participants distorted their evaluations of precise probabilities and payoffs in the direction of their emerging preferences and that they used their biased evaluations to update those preferences. As expected, information distortion mediated the effect of initial preferences on final choices and final preference strength. In a follow‐up experiment, we compared a standard measure of information distortion (based on comparisons to mean ratings in a no‐choice control task) to a more personalized measure (based on participants' own ratings in the control task) and found the mean‐based measure to be superior for the probability and payoff information in question. Other findings in Experiment 2 corroborated the results of Experiment 1. In both studies, the distortion of quantitative inputs in a simple task highlights the non‐normative circularity of the choice process. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Confidence judgments can be elicited in multiple ways. One of these procedures is to provide confidence judgments regarding each of a number of cases (individual judgments). A second procedure is to provide confidence judgments about a set of items (an aggregate judgment). Much research has demonstrated an aggregation effect—that individual judgments are more confident than aggregate judgments—within the cognitive knowledge domain. However, this effect has not previously been investigated with physical performance skill tasks. In three experiments, participants gave individual and aggregate judgments regarding the number of successful tosses they would make in either a ring toss, ping‐pong toss, or basketball toss task. In keeping with the aggregation effect, individual judgments were more confident than were aggregate judgments of success. Additionally, we eliminated the aggregation effect in Experiments 2 and 3 by employing a case‐specific base rate manipulation. Consistent with previous research with cognitive tasks, these results suggest that individual confidence judgments for physical skill tasks are determined primarily by characteristics associated with the individual case to be judged, whereas aggregate confidence judgments are determined by a more general evaluation of one's ability in the domain.
