The behavioural analysis of normal adults solving a combinatorial game—the subtraction game—that was previously studied by Gneezy, Rustichini, and Vostroknutov (2010) allows one to identify the transition from one strategy to a novel strategy. Based on protocol analysis and debriefing, two different strategies used by participants in this task are identified and compared with behavioural measurements (reaction times, accuracy, and mouse movements). One is a (forward) exploration strategy and the other is a more complex but efficient backward induction procedure. The clear determination of the transition from the standard forward exploration strategy to a novel internally generated strategy is established by both protocol reports and behavioural measurements. It allows for the potential investigation of the underlying transition to be carried out by cognitive neuroscience methods. A set of characteristics of such transitions to internally generated novel strategies are discussed. 相似文献

We conducted a systematic review and meta-analysis of anonymous surveys asking scientists whether they ever committed various forms of plagiarism. From May to December 2011 we searched 35 bibliographic databases, five grey literature databases and hand searched nine journals for potentially relevant studies. We included surveys that asked scientists if, in a given recall period, they had committed or knew of a colleague who committed plagiarism, and from each survey extracted the proportion of those who reported at least one case. Studies that focused on academic (i.e. student) plagiarism were excluded. Literature searches returned 12,460 titles from which 17 relevant survey studies were identified. Meta-analysis of studies reporting committed (N = 7) and witnessed (N = 11) plagiarism yielded a pooled estimate of, respectively, 1.7 % (95 % CI 1.2–2.4) and 30 % (95 % CI 17–46). Basic methodological factors, including sample size, year of survey, delivery method and whether survey questions were explicit rather than indirect made a significant difference on survey results. Even after controlling for these methodological factors, between-study differences in admission rates were significantly above those expected by sampling error alone and remained largely unexplained. Despite several limitations of the data and of this meta-analysis, we draw three robust conclusions: (1) The rate at which scientists report knowing a colleague who committed plagiarism is higher than for data fabrication and falsification; (2) The rate at which scientists report knowing a colleague who committed plagiarism is correlated to that of fabrication and falsification; (3) The rate at which scientists admit having committed either form of misconduct (i.e. fabrication, falsification and plagiarism) in surveys has declined over time. 相似文献

In this paper I shall adopt a possible reading of the notions of ‘explanatory indispensability’ and ‘genuine mathematical explanation in science’ on which the Enhanced Indispensability Argument (EIA) proposed by Alan Baker is based. Furthermore, I shall propose two examples of mathematical explanation in science and I shall show that, whether the EIA-partisans accept the reading I suggest, they are easily caught in a dilemma. To escape this dilemma they need to adopt some account of explanation and offer a plausible answer to the following ‘question of evidence’: What is a genuine mathematical explanation in empirical science and on what basis do we consider it as such? Finally, I shall suggest how a possible answer to the question of evidence might be given through a specific account of mathematical explanation in science. Nevertheless, the price of adopting this standpoint is that the genuineness of mathematical explanations of scientific facts turns out to be dependent on pragmatic constraints and therefore cannot be plugged in EIA and used to establish existential claims about mathematical objects. 相似文献

We examined lightness effects observed in Delboeuf and Ebbinghaus size-contrast illusions. Results of four experiments are reported. Experiment 1 was conducted with Delboeuf-like stimuli and shows that the disk that appears bigger appears either lighter or darker than the disk that appears smaller, depending on the contrast polarity between disks and background. Experiment 2 shows that the direction of these lightness effects is not influenced by the luminance of the size-contrast inducers. Experiment 3 shows that a similar lightness effect is also observed in modified Ebbinghaus size-contrast displays. Experiment 4 tested the presence of the size-contrast illusion in the stimuli used in experiments 2 and 3. 相似文献

If you can locate a target by using one reliable source of information, why would you use an unreliable one? A similar question has been faced in a recent study on homing pigeons, in which, despite the presence of better predictors of the goal location, the slope of the floor in an arena dominated the searching process. This piece of evidence seems to contradict straightforward accounts of associative learning, according to which behavior should be controlled by the stimulus that best predicts the reward, and has fueled interest toward one question that, to date, has received scarce attention in the field of spatial cognition: how are vertical spaces represented? The purpose of this communication is to briefly review the studies on this issue, trying to determine whether slope is a special cue--driving behavior irrespective of other cues--or simply a very salient one. 相似文献

Recent studies have tried to shed light on the automaticity of attentional shifts triggered by gaze and arrows with mixed results. In the present research, we aimed at testing a strong definition of resistance to suppression for orienting of attention elicited by these two cues. In five experiments, participants were informed with 100% certainty about the future location of a target they had to react to by presentation of either a direction word at the beginning of each trial or instructions at the beginning of each block. Gaze and arrows were presented before the target as uninformative distractors irrelevant for the task. The results showed similar patterns for gaze and arrows-namely, an interference effect when the distractors were incongruent with the upcoming target location. This suggests that the orienting of attention mediated by gaze and arrows can be considered as strongly automatic. 相似文献

The present paper is intended to analyse from a theoretical point of view the relationships between natural language and idiolects in the context of communication by means of the Davidson–Dummett controversy on the nature of language. I will explore from a pragmatic point of view the reliability of an alternative position inspired by the recent literalism/contextualism debate in philosophy of language in order to overcome some limitations of Dummett’s and Davidson’s perspectives on language, idiolects and communication. 相似文献

Le travail faisant l'objet de cet article s'inscrit dans le cadre d'un programme de recherche plus large qui s'intéresse à la variabilité individuelle des processus cognitifs et à son influence éventuelle sur les lois générates du développement de l'intelligence. Une partie des résultats a déjàété présentée dans d'autres publications auxquelles le lecteur pourra se référer pour plus de détails (par exemple, Rieben et al., 1983). Nous nous contenterons de les décrire brièvement afin d'introduire l'aspect spécifique sur lequel nous nous sommes centrées ici. 相似文献

ABSTRACT The present research contributes to the elucidation of an important aspect of Husserl’s interpretation of the history of philosophy, that is, his reading of the beginning of Western thought. In particular, it aims to clarify the sense in which Husserl deems Plato the father of the idea itself of philosophy as a science. As will be maintained, Husserl thinks of Socrates and Plato together as providing the first reform of philosophy, whose overall goal is to give reason (Vernunft) a universal method of self-justification against the general skepticism of the sophists. The analysis will be both systematically and historically oriented, for, it will try to both reconstruct Husserl’s interpretation of the background against which Plato first introduces the idea of philosophy as a science, and to show that what is truly at stake for Husserl is the nature of philosophy itself. 相似文献
