Péter Pongrácz Dorottya Hegedüs Beatriz Sanjurjo Adrienn Kővári Ádám Miklósi 《Learning and motivation》2013
The level of motivation (i.e. incentive power) is thought to be one of the most important factors affecting performance and learning in various tasks. We investigated whether reward quality has an effect on the performance of family dogs in a two-way object choice test in which they can find the hidden food by relying on distal momentary human pointing cues. In three experiments we varied (1) the type of food reward according to the subjects’ own preference; (2) the quality of the reward offered at the same time in the indicated and not-indicated locations; and (3) the order of the high or low quality rewards in consecutive sessions. In Experiment 1, we first tested whether dogs prefer one kind of reward over another. Then one group was tested with the ‘preferred’ food as reward in the indicated bowl, while dogs in the other group received the ‘non-preferred’ food as reward. We did not find any difference between the performance and choice latencies of the two groups. In Experiment 2 for the first group, the indicated bowl contained a piece of carrot and the not-indicated bowl was empty. In the second group the indicated bowl contained carrot, but the not-indicated bowl contained sausage. According to a preliminary preference test, most dogs prefer sausage over carrot invariably. After 20 trials, the two groups performed surprisingly similarly. There was no difference found between groups in the number of correct choices, incorrect choices and non-choices. However, the comparison between the first and last five trials revealed that subjects who found sausage when they chose the not-indicated bowl (did not follow the pointing) chose the non-indicated bowl significantly more often toward the end of their test session. In Experiment 3, each dog received two sessions with 12 pointing trials in each. For the first session, one group was rewarded with sausage and the other with carrot upon choosing the indicated bowl. In the second session, the indicated bowl contained dry dog food for both groups. We found that correct choices and response latencies did not change over two sessions in the ‘sausage’ group. In the ‘carrot’ group, the dogs chose faster in the second session, but their performance did not improve; in fact, they chose the not-indicated bowl more often than the indicated bowl. As a conclusion, we can say that reward quality had some effect on dogs’ choice behavior in these experiments. The drop in their performance was not drastic, taking into account the general refusal to eat one of the ‘rewards’ (carrot) during the preference tests and also during the test trials. It seems that incentive contrast may play a relatively minor role in dog-human social interactions. Appropriate reward quality can be very important in asocial problem solving tasks, but, when interacting with humans, following human signals may override the effect of changed incentive power. 相似文献

Morality has long been conceived as divinely instituted, so otherworldly, rules meant not to describe or explain behavior but to guide it towards an absolute good. The philosophical formulation of this theory by Plato was later grafted onto Christian thought by Augustine and Aquinas. The equally ancient theory of the Greek sophist Protagoras (that the good is relative to personal preferences and morality to man-made social customs) was forgotten until revived in the 18th and 19th centuries by such empiricists as David Hume and J. S. Mill. Then it was dismissed again in the 20th century by G. E. Moore and W. D. Ross as naturalistic fallacy, that is, conflation of what is with what ought to be. However, those who took this dismissive attitude themselves made the reverse mistake of conflating what ideally ought to be with what actually is. In other words, they mistook ideals for actualities. As B. F. Skinner (1971) said in Beyond Freedom and Dignity, sorting things out requires behaviorist parsing of the good (the personally reinforcing) and duty (the socially reinforced). 相似文献

Abstract Karen Horney, a Neo-Freudian analyst who immigrated from Germany to the USA, undertook the difficult task of developing a theory that remained concrete psychology without resorting to biology or to metapsychological entelechies. Although her basic construct, as in Freud, is a conflict between nature and culture, nature for her is the naturally endowed real self, which the neurotic abandons bowing to cultural pressures. This process of desertion is teleological and based on imagination, and is also creative. It entails the pursuit of a god-like idealized image of the self shaped according to narrow and despoiled values. Being interpersonal, Horney's theory avoids third-person objectification which creates a false distance; it thus remains (inter)subjective. A theory of interpersonal affect, it is dramatic before being dynamic. It also abandons claims to universality as it does to the “objectivity” of the natural sciences. Horney's focus on alienation brings her close to Hegel and Marx, a neglected fact, and she pioneered feminist and self-help theories. The difficulty in reading Horney is not her abstruseness, since her theory refuses technicism. It resides rather in that resistance created by what Althusser called interpellation: one feels her finger pointed at oneself as one reads. 相似文献

Ecological behaviour is often conceptualized as an instance of cooperating in a social dilemma situation. Thus, it has been argued to relate to dispositional tendencies of moral virtue and pro‐social orientation. To embed such notions in models of basic personality, we herein predicted that the recently proposed sixth basic personality factor, Honesty–Humility — which specifically pertains to individual differences in cooperativeness — is linked to environmental attitudes and ecological behaviour. Results from two studies (N = 137 and N = 531, respectively) supported these hypotheses and showed that Honesty–Humility explains incremental variance beyond the remaining, more classical five factors of personality. In addition, mediation analyses revealed that Honesty–Humility exerts part of its influence via individual differences in pro‐social value orientations. Individual tendencies to cooperate in social dilemma situations could thus be shown to form a bridge between basic personality dimensions and ecological behaviour.

The current study aimed to investigate value projection between Palestinians, Israelis, Americans, and Swiss as a function of their group's stance toward the Israeli‐Palestinian conflict. Drawing on image theory, we assumed that images—operationalized by value projection—would be a function not just of features of the target group, but of the rater group's relationship with the target group. Value projection can be seen as an indicator of (de)humanization as values represent goals and desirable behaviors of a person. We therefore expected higher projection to ally than to enemy groups, whereas we expected no difference in projection to out‐groups with neutral relations. Results show that allies did indeed project Security and Power to a higher degree to each other than to enemies, and enemies showed no, or even negative, projection onto each other. The ally of the enemy (Americans) was projected less negatively by Palestinians than vice versa, pointing to the higher complexity of third‐party images as opposed to the more classical ally and enemy images. As expected, Swiss students showed almost no difference in projection to the different out‐groups. These results confirm that the relationship between groups (e.g., alliance, enmity) rather than a consensual view of particular nations determines images. 相似文献

The United States has made a significant effort and investment in STEM education, yet the size and the composition of the STEM workforce continues to fail to meet demand. It is thus important to understand the barriers and factors that influence individual educational and career choices. In this article, we conduct a literature review of the current knowledge surrounding individual and gender differences in STEM educational and career choices, using expectancy–value theory as a guiding framework. The overarching goal of this paper is to provide both a well-defined theoretical framework and complementary empirical evidence for linking specific sociocultural, contextual, biological, and psychological factors to individual and gender differences in STEM interests and choices. Knowledge gained through this review will eventually guide future research and interventions designed to enhance individual motivation and capacity to pursue STEM careers, particularly for females who are interested in STEM but may be constrained by misinformation or stereotypes. 相似文献

Abstract The use of shock tactics to motivate people to learn more about AIDS and to take appropriate protective action characterised the approach adopted by the national health authorities in Australia during 1987. The rationale underlying this approach is critically examined, particularly in the light of results obtained from surveys of community concern and knowledge about AIDS in the state of South Australia before the campaign and after it had been in progress for some five months. Contrary to expectations no significant increases in either personal or social concern were found; in fact, among older respondents personal concern had decreased significantly. Levels of knowledge about AIDS, in general, remained unchanged, apart from an increase in acceptance of the safety of blood transfusions from a very low to a somewhat higher level. Among a minority of respondents (29%) who approved of the campaign and also believed they had been influenced by it, personal and social concern about AIDS, but not knowledge, was significantly greater than among others. The view that fear-inducing techniques can be used to bring about increases in knowledge about AIDS was not supported, although some positive effects on the social attitudes of respondents most affected by the campaign are suggested. 相似文献

The focus of this paper is the prima facie plausible view, expressed by the principle of Counter-Closure, that knowledge-yielding competent deductive inference must issue from known premises. I construct a case that arguably falsifies this principle and consider five available lines of response that might help retain Counter-Closure. I argue that three are problematic. Of the two remaining lines of response, the first relies on non-universal intuitions and forces one to view the case I construct as exhibiting a justified, true belief to which none of the usual diagnoses of knowledge failure in Gettier cases apply. The second line involves claiming that Fake Barns and its ilk are misdiagnosed by epistemological orthodoxy as Gettier cases. We are thus confronted by a trilemma: either the case I discuss undermines the first-blush plausible principle of Counter-Closure; or the case I discuss instantiates a novel kind of Gettier case; or a popular conception of a key range of alleged Gettier cases must be rejected. No matter which horn we choose, the case points to a philosophically curious conclusion. 相似文献

Orthodox decision theory gives no advice to agents who hold two goods to be incommensurate in value because such agents will have incomplete preferences. According to standard treatments, rationality requires complete preferences, so such agents are irrational. Experience shows, however, that incomplete preferences are ubiquitous in ordinary life. In this paper, we aim to do two things: (1) show that there is a good case for revising decision theory so as to allow it to apply non-vacuously to agents with incomplete preferences, and (2) to identify one substantive criterion that any such non-standard decision theory must obey. Our criterion, Competitiveness, is a weaker version of a dominance principle. Despite its modesty, Competitiveness is incompatible with prospectism, a recently developed decision theory for agents with incomplete preferences. We spend the final part of the paper showing why Competitiveness should be retained, and prospectism rejected. 相似文献
