Four experiments demonstrate that closing one’s eyes affects ethical judgment and behavior because it induces people to mentally simulate events more extensively. People who considered situations with their eyes closed rather than open judged immoral behaviors as more unethical and moral behaviors as more ethical. In addition, considering potential decisions with closed eyes decreased stated intentions to behave ethically and actual self-interested behavior. This relationship was mediated by the more extensive mental simulation that occurred with eyes closed rather than open, which, in turn, intensified emotional reactions to the ethical situation. We discuss the implications of these findings for moral psychology and ethical decision making. 相似文献

Prior research has claimed that people exaggerate probabilities of success by overestimating personal control in situations that are heavily or completely chance-determined. We examine whether such overestimation of control persists in situations where people do have control. Our results suggest a simple model that accounts for prior findings on illusory control as well as for situations where actual control is high: People make imperfect estimates of their level of control. By focusing on situations marked by low control, prior research has created the illusion that people generally overestimate their level of control. Across three studies, we show that when they have a great deal of control, people under-estimate it. Implications for research on perceived control and co-variation assessment are discussed. 相似文献

Bringing ethics into focus: How regulatory focus and risk preferences influence (Un)ethical behavior
In four laboratory studies, we find that regulatory focus induced by situational cues (such as the framing of an unrelated task) or primed influences people’s likelihood to cross ethical boundaries. A promotion focus leads individuals to be more likely to act unethically than a prevention focus (Studies 1, 2, and 3). These higher levels of dishonesty are explained by the influence of a person’s induced regulatory focus on his or her behavior toward risk. A promotion focus leads to risk-seeking behaviors, while a prevention focus leads to risk avoidance (Study 3). Through higher levels of dishonesty, promotion focus also results in higher levels of virtuous behavior (Studies 2 and 3), thus providing evidence for compensatory ethics. Our results also demonstrate that the framing of ethics (e.g., through an organization’s ethics code) influences individuals’ ethical behavior and does so differently depending on an individual’s induced regulatory focus (Study 4). 相似文献

The aim of this work is to understand how face processing develops from birth to 4 months by modelling some face processing abilities of infants between these ages. The neural model reproduces experimental data regarding both visual preferences at birth and right hemisphere behaviour in 4‐month‐old infants. The model shows that two basic properties may be sufficient to simulate face preference at birth: (a) tuning selectivity of visual neurons for spatial frequencies and (b) limited vision (CSF) of newborns. Three additional properties are sufficient to match experimental data on face processing at 4 months: (c) plasticity of lateral connections as modelled by Bayesian networks, (d) amplification of eye importance and (e) mother bias induced by the high probability of seeing mother’s face. These conditions suggest that the neural substratum for face processing could be, at birth, the retina‐V1/V2‐colliculus system, and at 4 months, the activation of the RH face‐Fusiform area, with configural representations stored in lateral connections. 相似文献

This study examined newborns' face preference using images of natural and scrambled faces in which the location of the inner features was distorted. The results demonstrate that newborns' face preference is not confined to schematic configurations, but can be obtained also with veridical faces. Moreover, this phenomenon is not produced by a specific bias toward the face geometry, but derives from a domain-general bias toward configurations with more elements in the upper than in the lower half (i.e., top-heavy patterns). These results suggest that it may be unnecessary to assume the existence of a prewired tendency to orient toward the face geometry, and support the idea that faces do not possess a special status in newborns' visual world. 相似文献

One of the basic limitations on visual perception is that it is impossible, in any given moment, to see the world sharply and full of colors beyond the central area of the visual field. This fact was popularized and brought to the attention of artists in the nineteenth century. To accurately represent the 'impression', or vision of a single glance, an artistic work should contain only a central area in focus surrounded by a progressively greater blur. The work of the Italian sculptor Medardo Rosso (1858-1928) may be the first artistic representation of differences in central and peripheral acuity. Despite using the medium of sculpture, typically three-dimensional, Rosso conceived of his art as two-dimensional because in a given moment it is possible to view a scene from only one viewpoint. The analysis of Rosso's photographs of his own sculptures emphasizes the areas of detail and relative blur, allowing a reconstruction of his point de vue unique--where the observer should stand when viewing that specific sculpture. We argue that the role of central and peripheral vision in subjective perception is critical to understanding the work of Rosso, aptly defined by critics as monument d'un instant. 相似文献

Cholinergic dependence of taste memory formation: evidence of two distinct processes 总被引:3,自引:0,他引:3

Learning the aversive or positive consequences associated with novel taste solutions has a strong significance for an animal's survival. A lack of recognition of a taste's consequences could prevent ingestion of potential edibles or encounter death. We used conditioned taste aversion (CTA) and attenuation of neophobia (AN) to study aversive and safe taste memory formation. To determine if muscarinic receptors in the insular cortex participate differentially in both tasks, we infused the muscarinic antagonists scopolamine at distinct times before or after the presentation of a strong concentration of saccharin, followed by either an i.p. injection of a malaise-inducing agent or no injection. Our results showed that blockade of muscarinic receptors before taste presentation disrupts both learning tasks. However, the same treatment after the taste prevents AN but not CTA. These results clearly demonstrate that cortical cholinergic activity participates in the acquisition of both safe and aversive memory formation, and that cortical muscarinic receptors seem to be necessary for safe but not for aversive taste memory consolidation. These results suggest that the taste memory trace is processed in the insular cortex simultaneously by at least two independent mechanisms, and that their interaction would determine the degree of aversion or preference learned to a novel taste. 相似文献

The case is presented of a semantic dementia patient, who shows a deficit selective for (i) conceptual class (living things), (ii) attribute processing (visual features) and affecting (iii) input-output modalities at the same processing stage (matching stored representation to attributes). The first experimental part aims at exploring the specific stage/process at which semantic knowledge breaks down through multi-modality tasks, devised to tap different levels within the semantic elaboration flow. The second focuses on the differences between category vs. attribute knowledge across various modalities. The core nature of the patient's deficit is investigated through a close comparison of her damage to a specific processing stage across modalities in the light of her class and attribute-specific impairment. The complex pattern of findings is discussed according to current theoretical accounts of semantic memory organization. Finally, the relevance of the adoption of a broad perspective when dealing with semantic memory impairments is highlighted. 相似文献
