Guilt is an important social and moral emotion. In addition to feeling unpleasant, guilt is metaphorically described as a “weight on one''s conscience.” Evidence from the field of embodied cognition suggests that abstract metaphors may be grounded in bodily experiences, but no prior research has examined the embodiment of guilt. Across four studies we examine whether i) unethical acts increase subjective experiences of weight, ii) feelings of guilt explain this effect, and iii) whether there are consequences of the weight of guilt. Studies 1–3 demonstrated that unethical acts led to more subjective body weight compared to control conditions. Studies 2 and 3 indicated that heightened feelings of guilt mediated the effect, whereas other negative emotions did not. Study 4 demonstrated a perceptual consequence. Specifically, an induction of guilt affected the perceived effort necessary to complete tasks that were physical in nature, compared to minimally physical tasks. 相似文献

Background
Several medical conditions can affect and disrupt human sexuality. The alteration of sexuality in these medical conditions often hinder effective communication and empathy between the patients and their sexual partners because of cultural attitudes, social norms and negative feelings such as anxiety and guilt. Validated and standardized sexual inventories might therefore help resolve this problem. The objective of this cross-sectional study was to obtain data on the prevalence of male sexual dysfunction (SD) among Ghanaians with various medical conditions residing in Kumasi. 相似文献4.
Mechanisms of long-distance seed dispersal 总被引:4,自引:0,他引:4

Growing recognition of the importance of long-distance dispersal (LDD) of plant seeds for various ecological and evolutionary processes has led to an upsurge of research into the mechanisms underlying LDD. We summarize these findings by formulating six generalizations stating that LDD is generally more common in open terrestrial landscapes, and is typically driven by large and migratory animals, extreme meteorological phenomena, ocean currents and human transportation, each transporting a variety of seed morphologies. LDD is often associated with unusual behavior of the standard vector inferred from plant dispersal morphology, or mediated by nonstandard vectors. To advance our understanding of LDD, we advocate a vector-based research approach that identifies the significant LDD vectors and quantifies how environmental conditions modify their actions. 相似文献

The use of human-assisted colonization for species affected by climate change is now being adopted by some conservationists but remains controversial. In order to deter extreme translocation actions, a decision framework is proposed that incorporates a biogeographical approach. 相似文献

Attitude to morality, reflecting cultural norms and values, is considered unique to human social behavior. Resulting moral behavior in a social environment is controlled by a widespread neural network including the dorsolateral prefrontal cortex (DLPFC), which plays an important role in decision making. In the present study we investigate the influence of neurophysiological modulation of DLPFC reactivity by means of transcranial direct current stimulation (tDCS) on moral reasoning. For that purpose we administered anodal, cathodal, and sham stimulation of the left DLPFC while subjects judged the appropriateness of hard moral personal dilemmas. In contrast to sham and cathodal stimulation, anodal stimulation induced a shift in judgment of personal moral dilemmas towards more non-utilitarian actions. Our results demonstrate that alterations of left DLPFC activity can change moral judgments and, in consequence, provide a causal link between left DLPFC activity and moral reasoning. Most important, the observed shift towards non-utilitarian actions suggests that moral decision making is not a permanent individual trait but can be manipulated; consequently individuals with boundless, uncontrollable, and maladaptive moral behavior, such as found in psychopathy, might benefit from neuromodulation-based approaches. 相似文献

Guilt and responsibility In criminal law, the notion of guilt is based on the metaphysical principle of free will implying the ability to “do otherwise” under identical physico‐psychical conditions. This stands in contradition to scientific thinking as well as psychological and neurobiological insight into the development of personality and motive structures. It is proposed to replace the notion of free will by that of formation of will in private law. This implies the ability to adequately deliberate the conditions and possible consequences of one's own actions. This ability is understood as the result of normal development of the brain and its cognitive, emotional and executive functions. From this derives the responsibility of a person for his or her actions. 相似文献

Superior psychical functions (skills) are usually formed in great subjective uncertainty conditions. Because of that exact knowledge of information mechanisms of behavior activity under uncertainty conditions is very importent. Some difficulties of traditional notions (classic behavior act model developed by P. K. Anokhin, systems quantization of behavior) are discussed. The model of probabilitive training allows to describe various training uncertainty conditions, and it operates as the Anokhin model in a specific case. The system-shaping factor in this model is an adaptive result. Afferent synthesis, aim for action, acceptor of the action result and the programme of actions have the traditional senses. Besides those it is proposed to use a concept of probability decision to alter the program of action, as well as an idea of memory buffer (results of search reactions). The organizational features of the functional system of behavior under great uncertainty conditions should be taken into account while specifying the informational mechanism responsible for systems quantization of behavior. The above mechanism can be used for explain the discreteness of an action in the program alteration process when the same quantum of behavior is implemented. These ideas are profitable for systems analysis of superior psychical functions, based on the reflex formation under environmental uncertainty conditions. 相似文献

The biological roots of morality 总被引:2,自引:0,他引:2
Francisco J. Ayala 《Biology & philosophy》1987,2(3):235-252
The question whether ethical behavior is biologically determined may refer either to thecapacity for ethics (e.i., the proclivity to judge human actions as either right or wrong), or to the moralnorms accepted by human beings for guiding their actions. My theses are: (1) that the capacity for ethics is a necessary attribute of human nature; and (2) that moral norms are products of cultural evolution, not of biological evolution.Humans exhibits ethical behavior by nature because their biological makeup determines the presence of the three necessary, and jointly sufficient, conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgements; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself, but as a necessary consequece of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection.Since Darwin's time there have been evolutionists proposing that the norms of morality are derived from biological evolution. Sociobiologists represent the most recent and most subtle version of that proposal. The sociobiologists' argument is that human ethical norms are sociocultural correlates of behaviors fostered by biological evolution. I argue that such proposals are misguided and do not escape the naturalistic fallacy. The isomorphism between the behaviors promoted by natural selection and those sanctioned by moral norms exist only with respect to the consequences of the behaviors; the underlying causations are completely disparate.This article is based on a paper presented at the International Symposium onBiological Models of Human Action, Palma de Mallorca, Spain, 16–18 December 1985. 相似文献

Activity in posterior parietal cortex is correlated with the relative subjective desirability of action 总被引:12,自引:0,他引:12
Behavioral studies suggest that making a decision involves representing the overall desirability of all available actions and then selecting that action that is most desirable. Physiological studies have proposed that neurons in the parietal cortex play a role in selecting movements for execution. To test the hypothesis that these parietal neurons encode the subjective desirability of making particular movements, we exploited Nash's game theoretic equilibrium, during which the subjective desirability of multiple actions should be equal for human players. Behavior measured during a strategic game suggests that monkeys' choices, like those of humans, are guided by subjective desirability. Under these conditions, activity in the parietal cortex was correlated with the relative subjective desirability of actions irrespective of the specific combination of reward magnitude, reward probability, and response probability associated with each action. These observations may help place many recent findings regarding the posterior parietal cortex into a common conceptual framework. 相似文献

The publication of unfounded health claims on small molecules in peer-reviewed scientific literature is a problem that requires attention. It undermines the evidence-based decision making processes of modern-day society, weakens the credibility of the scientific enterprise, and diverts resources to futile research efforts. In the present essay we discuss some human and scientific causes behind the issue. We propose a number of actions to be taken up by scientists, referees and publishers. One particularly important factor is the issue of enigmatic compound behavior in biological assays. We therefore also introduce the idea of biological filters, a pattern recognition method to triage enigmatic compounds into valuable hits and false positives, based on the entirety of their biological effects in cell-based systems. 相似文献

Background
Anorexia nervosa (AN) patients are assumed to express high levels of guilt and envy. Ultimatum game (UG) is a standard behavioral task that focuses on interpersonal behavior when splitting a sum of money between two players. UG studies consistently demonstrate that people tend to decrease their inequity in outcomes, one explanation being that economically irrational decision-making may partly arise from the emotions guilt and envy. We assumed that AN patients would perform excessively fair in UG, reflecting high guilt and envy.Methods
We utilized UG to investigate the characteristics of guilt and envy among 24 Japanese AN patients and 22 age-matched healthy controls (HC). The relation between the outcome of UG and decision strategy confirmed by post-experimental questionnaires was analyzed.Results
As proposer, AN offered a larger amount to the responder compared with HC (p?=?0.002) while, on the other hand, as responder, AN demanded much higher allocation to accept the offer compared with HC (p?=?0.026). Regarding the strategy as responder, AN put more emphasis on fairness and less emphasis on monetary reward compared with HC (p?=?0.046, p?=?0.042, respectively).Conclusions
The results indicate that Japanese AN patients demonstrate strong preference for fairness, with high guilt and high envy. High sensitivity to guilt and envy of AN patients can affect not only their own behavior concerning eating attitude and body shape, but also decision-making in interpersonal situations. Behavioral experimental settings among social situations will enable us to evaluate and help actual decision-making in the real life of patients.14.

Introduction and objectiveThe experience of family caregivers after nursing home admission has received much less attention, probably because many caregivers experience an initial sense of initial emotional relief. However, for some caregivers nursing home admission is a stressor despite the reduced physical burden of caregiving. Caregiver distress following institutionalization has been related to the new burdens and challenges encountered in the nursing home. Ambivalence and guilt related to the institutionalization decision have been identified as sources of stress. Therefore, this study examined the effect of guilt and well-being on the perceived stress of family caregivers of institutionalized dependent persons.Materials and methodsTwo hundred and one family caregivers of institutionalized persons in a nursing home (La Rioja, Spain) participated. Perceived stress, caregiving guilt and subjective well-being, sociodemographic and caregiving-related variables were assessed. Linear regression analyses and correlations between variables were performed.ResultsGuilt and five dimensions of well-being (anxiety, vitality, self-control and depression, except general health) significantly predicted stress (R2adj = .552 (F (6, 198) = 41.71, P<.001)). The effect size was large (95% CI = .461).ConclusionsPaying attention to family caregivers’ feelings of guilt during institutionalization is important. This will enable the design and implementation of psychosocial interventions that improve caregiver adjustment immediately after institutionalization. 相似文献

Depression in the elderly is often thought to have a different clinical presentation in many patients. This so-called atypical depression is characterised by less sadness and feelings of guilt and more somatic symptoms, impaired cognition and behavioural symptoms. Studies that compare depressive signs and symptoms in elderly and younger patients are reviewed. Published studies do not support the suggestion that major depression in the elderly often have a different clinical presentation. Vascular depression and depression in patients with severe dementia may be exceptions. Conceptual and methodological issues that play an important role are discussed. 相似文献

An obstacle to abortion exists in the form of abortion ‘counselling’ that discourages women from terminating their pregnancies. This counselling involves providing information about the procedure that tends to create feelings of guilt, anxiety and strong emotional reactions to the recognizable form of a human fetus. Instances of such counselling that involve false or misleading information are clearly unethical and do not prompt much philosophical reflection, but the prospect of truthful abortion counselling draws attention to a delicate issue for healthcare professionals seeking to respect patient autonomy. This is the fact that even accurate information about abortion procedures can have intimidating effects on women seeking to terminate a pregnancy. Consequently, a dilemma arises regarding the information that one ought to provide to patients considering an abortion: on the one hand, the mere offering of certain types of information can lead to intimidation; on the other hand, withholding information that some patients would consider relevant to their decision‐making is objectionably paternalistic on any standard account of the physician‐patient relationship. This is an unsettling conclusion for the possibility of setting fixed professional guidelines regarding the counselling offered to women who are considering abortion. Thus, abortion ought to be viewed as an illuminating example of a procedure for which the process of securing informed consent ought to be highly context‐sensitive and responsive to the needs of each individual patient. This result underscores the need for health care professionals to cultivate trusting relationships with patients and to develop finely tuned powers of practical judgment. 相似文献

In both animal and human behavioral repertoires, classical expected utility theory is considered a fundamental element of decision making under conditions of uncertainty. This theory has been widely applied to problems of animal behavior and evolutionary game theory, as well as to human economic behavior. The Allais paradox hinges on the expression of avoidance of bankruptcy by humans, or death by starvation in animals. This paradox reveals that human behavioral patterns are often inconsistent with predictions under the classical expected utility theory as formulated by von Neumann and Morgenstern. None of the many attempts to reformulate utility theory has been entirely successful in resolving this paradox with rigorous logic. We present a simple, but novel approach to the theory of decision making, in which utility is dependent on current wealth, and in which losses are more heavily weighted than gains. Our approach resolves the Allais paradox in a manner that is consistent with how humans formulate decisions under uncertainty. Our results indicate that animals, including humans, are in principle risk-averse. Our restructuring of dynamic utility theory presents a basic optimization scheme for sequential or dynamic decisions in both animals and humans. 相似文献

Humans can learn under a wide variety of feedback conditions. Reinforcement learning (RL), where a series of rewarded decisions must be made, is a particularly important type of learning. Computational and behavioral studies of RL have focused mainly on Markovian decision processes, where the next state depends on only the current state and action. Little is known about non-Markovian decision making, where the next state depends on more than the current state and action. Learning is non-Markovian, for example, when there is no unique mapping between actions and feedback. We have produced a model based on spiking neurons that can handle these non-Markovian conditions by performing policy gradient descent [1]. Here, we examine the model’s performance and compare it with human learning and a Bayes optimal reference, which provides an upper-bound on performance. We find that in all cases, our population of spiking neurons model well-describes human performance. 相似文献

Pet owners often experience complex and profound grief reactions when their animals are euthanized. Veterinary staff are increasingly being called upon to be aware of and to respond to the grief reactions of pet owners at this critical time. The objectives of this study were to identify pet owners who are most at risk of grief and to suggest veterinary interventions during the euthanasia process. A convenience sample of 409 pet owners whose animals had been euthanized in the past year took part in a survey. Variables of interest included pet and pet-owner demographics, pet-death characteristics, attachment to pet, and bereavement reactions. Stepwise multiple regression analyses were conducted to identify factors related to the three grief reaction subtypes: sorrow, anger, and guilt. Results indicated that attachment to pets was a strong predictor of feelings of grief/sorrow (p < 0.001) and anger (p < 0.001). Sudden death was also related to feelings of anger (p < 0.05). Cancer diagnosis was negatively related to feelings of anger (p < 0.05) and guilt (p < 0.01). The findings from this study provide additional insight into the complexity of grief following pet euthanasia. For veterinary staff, anticipating the needs of pet owners and supporting them through the grief process is an integral role. Understanding which pet owners are at greatest risk of grief is an important initial step, followed by empathic communications, sensitive interactions, and the provision of grief support. 相似文献

Affiliative social motivation and behavior, that is, sociability that includes attachment, prosocial behavior (sharing, caring and helping) and empathy (the ability to understand and share the feelings of others), has high variability in the human population, with a portion of people outside of the normal range. While psychiatric disorders and autism spectrum disorders are typically associated with a deficit in social behavior, the opposite trait of hypersociability and indiscriminate friendliness are exhibited by individual with specific neurodevelopmental disorders and following early adverse care. Here we discuss both genetic and environmental factors that cause or increase the risk for developing pathological hypersociability from human to rodent models. 相似文献
