In the present study, we applied Valins’ (1966) bogus bodily feedback paradigm to investigate the roles of cognitive appraisal (tele)presence, and emotion in the context of media usage. Participants (N=30) viewed short sequences of a TV show, whereby false heart rate feedback was provided. In line with Valins’ paradigm, the manipulation we used in this study included two levels: high vs. low false heart rate feedback. We assessed presence, enjoyment, and the real heart rate. Participants reported stronger experiences of presence and enjoyed the clips more when they wrongly believed that they had been aroused. Since bogus feedback increases the sensation of presence, the results indicate that presence—like emotions—can be influenced by cognitive appraisals. It is likely that the false heart rate feedback was attributed to the stimulus, which in turn enhanced the sensation of presence.  相似文献

This study examines the impact of likability on memory accuracy and memory conformity between two previously unacquainted individuals. After viewing a crime, eyewitnesses often talk to one another and may find each other likable or dislikable. One hundred twenty-seven undergraduate students arrived at the laboratory with an unknown confederate and were assigned to a likability condition (i.e., control, likable or dislikable). Together, the pair viewed pictures and was then tested on their memory for those pictures in such a way that the participant knew the confederate's response. Thus, the participant's response could be influenced both by his or her own memory and by the answers of the confederate. Participants in the likable condition were more accurate and less influenced by the confederate, compared with the other conditions. Results are discussed in relation to research that shows people are more influenced by friends than strangers and in relation to establishing positive rapport in forensic interviewing.  相似文献

Abstract: The common practice of giving (comparing, rejecting and inferring) explanations of phenomena is at the root of articulate learning, including the enterprises we collect under the noun ‘science’. The way that practice privileges a single item from the myriad relevant to any phenomenon tells us something about articulateness itself.  相似文献

Abstract

In Wittgenstein: On Rules and Private Language, Saul Kripke argues for an extreme form of meaning scepticism. One influential reply to Kripke’s arguments was developed by David Lewis. The reply developed by Lewis makes use of the notion of mind-independent relations of similarity and difference. The aim of the paper is to argue that Lewis’ reply is not satisfactory: the challenge to find a refutation of Kripke’s sceptical arguments remains unmet.  相似文献

Two matching-to-sample (MTS) and four same/different (S/D) experiments employed tests to distinguish between item-specific learning and relational learning. One MTS experiment showed item-specific learning when concept learning failed (i.e., no novel-stimulus transfer). Another MTS experiment showed item-specific learning when pigeons’ novel-stimulus transfer decreased because they chose familiar training comparisons instead of matching novel comparisons. In 8-item and 3-item S/D tasks, pigeons and monkeys were accurate with unfamiliar training-stimulus pairings, stimulus inversions, and distorted stimuli, suggesting relational learning within a domain restricted to the training stimuli (i.e., no novel-stimulus transfer). In 32-item S/D tasks, pigeons with previous 8-item training showed less transfer than those without prior training, suggesting a carryover of restricted-domain relational learning. Pigeons shifted from 1024-item to 8-item S/D tasks showed reinstatement of restricted-domain relational learning. These findings are important in specifying which types of learning occur in these tasks, showing that subjects failing novel-stimulus transfer are not required to switch from item-specific to relational learning as a training set is expanded, and demonstrating that concept learning failure is not proof of item-specific learning.  相似文献

Beginning with his work in the mid-1930s, Heidegger's later thought is generally considered to pose severe interpretative difficulties, even for those well acquainted with Being and Time. It is often claimed that his later thought either defies reconstruction because of its arcane nature or that it should not be reconstructed because doing so compromises its subtleties. It is argued that this 'availability problem' with Heidegger's later thought is not insurmountable, at least not with regard to one of its major strands, his views on the relation of art to truth. An interpretation of 'The Origin of the Work of Art' is proposed that views its major arguments as extensions of Heidegger's view on truth and the nature of worlds in Being and Time. To this end, a new account of the relationship of two pairs of terms crucial to the understanding of the ontological significance of the work of art and its truth is offered: (a) 'earth' and 'world' and (b) 'concealment' and 'un-concealment'. What emerges is a Kant-like claim that a necessary condition for the possibility of worlds is that things stand to be taken up into worlds in virtue of a character they have abstracted from their involvements in any one world. Artworks, if they are 'true' art, show this by allowing the thing that they are to support a wide range of possible understandings, displaying the fact that no one set of understandings can exhaust the 'thingly' nature of the work. In addition to clarifying that aspect of Heidegger's account of truth that requires un-concealment to depend on residual concealment, this understanding of the structure of the artwork accounts for the power Heidegger ascribes to certain art to inaugurate worlds. I conclude by making some suggestions, against the background of the interpretation of the art essay, on how to understand the 'turn' in Heidegger's thought as a deepening inquiry into the nature of truth.  相似文献

In this study, the authors examined the interplay between biomechanics and control strategies in the resolution of excess degrees of freedom at the joint level. Seven participants made aimed arm movements from 30 starting points and several starting postures to targets. Final arm postures for movements to a target exhibited substantial joint angle variation. Through regression modeling and by comparing observed final arm postures with biomechanically plausible postures, the authors identified 3 kinematic strategies: (a) Maintain deviations from the average angle at the starting point to the joint's final posture; (b) make torso rotations that are a fixed proportion of shoulder rotations; and (c) adopt a characteristic combination of 4 wrist-positioning approaches. The results demonstrated that kinematic strategies can account for substantial variance in final arm postures, if one takes into account 2 types of individual differences—those that arise inevitably from biomechanical constraints and those that reflect choices in movement strategy.  相似文献
