In this paper, I defend the view that a person performs an action A intentionally only if she intends to A against Michael Bratman’s alleged counterexample to it: the videogame case. I object that Bratman is mistaken in assuming that the consistency among an agent’s intentions is about the consistency among intended goals or objectives. Instead, I argue that the real reason why an agent’s intentions need to be consistent with each other is due to the necessity of the compatibility of corresponding efforts of trying. But unfortunately for Bratman, this efforts-based consistency constraint – as a replacement of the objectives-based consistency constraint – cannot save the videogame case.  相似文献

文采用延迟反应的同一字判断任务,记录了大学生被试由部件数不同的两种残缺汉字诱发的事件相关电位(ERP)。结果发现部件少(笔画删除)比部件多(部件删除)的残缺字产生更小的P200,更大的N400,表明简单部件在合体字识别中起到一种中间层单元的作用;P200效应符合关于部件少比部件多的残缺字激活更多的部件家族成员的假设,而更多家族成员的激活使残缺字的整字内部表征受到的侧抑制更多,体现为更大的N400。双效应支持多层交互激活模型及其侧抑制机制。  相似文献

The necessity of retrieving complex attribute information from long‐term memory has been shown to elevate processing costs and boost the use of simple decision heuristics. This effect was confined to verbal as opposed to pictorial attribute information. In a large‐scale experiment (N = 151), either verbal or pictorial information for inferences had to be retrieved from long‐term memory. Concurrent secondary tasks either interfered with the Central Executive, the Phonological Loop, or the Visuo‐Spatial Sketchpad. These are hypothetical components of working memory responsible for processing different information formats. Whereas the information format massively affected strategy selection, there was an additive rather than interactive effect of secondary task, suggesting enhanced retrieval costs irrespective of the information format. An additional analysis in terms of a similarity match as proposed by exemplar‐based models did not enhance the explanation of the data. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

The ability to group dissimilar stimuli into categories on the basis of common stimulus relations (stimulus equivalence) or common functional relations (functional equivalence) has been convincingly demonstrated in verbally competent subjects. However, there are investigations with verbally limited humans and with nonhuman animals that suggest that the formation and use of classification schemes based on equivalence does not depend on linguistic skills. The present investigation documented the ability of two California sea lions to classify stimuli into functional classes using a simple discrimination reversal procedure. Following the formation of functional classes in this context, the second experiment showed transfer of the relations that emerged between class members to a matching-to-sample procedure. The third experiment demonstrated that the functional classes could be expanded through traditionally defined equivalence relations. In these three experiments, appropriate within-class responding produced class-specific food reinforcers. Experiment 3 addressed the role of these reinforcers in equivalence classification and showed that the class-specific reinforcers were sufficient to relate new stimuli to the functional classes. These findings show that sea lions can form equivalence classes in simple and conditional discrimination procedures, and that class-specific reinforcers can become equivalence class members.  相似文献

In studies of simple and conditional discrimination, procedures are needed to measure those aspects of stimuli that control behavior. The blank comparison procedure is one such procedure. It was designed explicitly for assessing S+ and S- functions when discriminative stimuli are presented simultaneously. In this procedure, a neutral stimulus serves sometimes as S+ and sometimes as S-. Its discriminative function is defined in relation to other stimuli in the display. The present study aimed to prepare 2 infant female capuchin monkeys for the effective use of the blank comparison procedure in a simple discrimination task. First, simple discrimination training was applied up to a stable accuracy criterion of ≥90%. This training was followed by the replacement of S+ and then of S- stimuli with new stimuli. Ultimately, trials with the blank comparison were introduced. Following this sequence, both monkeys immediately displayed highly accurate blank-comparison performances without the need for stimulus control shaping or other preparatory discrimination training. Thus, this procedure sequence may be an efficient, effective method for establishing blank-comparison baselines for experimental analyses of S+/S- discriminative functions and perhaps for other applications in teaching simple and conditional discrimination performances to this species and others.  相似文献

I begin this paper by outlining two senses of “phenomenology.” First, the “what it is like” or “analytic tradition” sense: the verbalization of qualitative states of consciousness of which we are aware. Second, the “Continental” sense: the rigorous study of the structures of consciousness. I outline the ways in which these two senses diverge. First, Continental phenomenology involves a diversified account of consciousness, states of awareness, and the human person. The phenomenologist articulates this account not by introspection but via acts of phenomenological reflection concerning eidetic intuitions about essential structural features. Second, via the method of “sense explication,” the phenomenologist can articulate an account of passive and subconscious states which we are not strictly “aware” of. The conclusion shows these divergences of senses are sometimes overlooked, leading to equivocation. Zahavi and Gallagher must be employing the “what it is like” sense when they make certain “phenomenological” arguments concerning social cognition, yet Spaulding’s ensuing critique of phenomenology is directed at Continental phenomenology. Also, it is only phenomenology in the “what it is like” sense which cannot contribute to subpersonal psychology. Genetic Continental phenomenology describes the lawful relations amongst the precursors and preconditions which give rise to conscious experience, constituting a type of (non-causal) subpersonal explanation.  相似文献

The variable substitution and power-series techniques are used for the asymptotic analytical derivation of the governing equation of a transverse surface wave. The results reveal that the transverse wave can propagate along the surface of a functionally graded infinite half space in various modes, and that their dispersion relations are normal. For certain cases, energy is concentrated on the surface region to a depth of several wavelengths. A new theoretical foundation based on the transverse surface wave can be provided for graded-material characterization by experimental measurement. Some phenomena of seismic wave propagation may also be explained.  相似文献

ABSTRACT

This paper considers the characteristics of severe plastic deformation (SPD) to estimate its efficacy and to compare different processing techniques. In contrast to effective strains by von Mises and Hencky, the rotation component of the strain rate is included in the analysis as a mode of deformation, which ranges from simple shear to pure shear. Distortions of material elements during a uniform plane plastic flow are calculated using a kinematic approach. For the fixed deformation mode, the current state is defined by the accumulated shears that are identical to the von Mises effective shear strains. In specific cases of pure shear and simple shear, the accumulated shears match the specific distortions of round or square elements prescribed by Hencky or von Mises approach, respectively. The mode of deformation is important to the structural effects of SPD. In general, two separated characteristics, accumulated shear and the coefficient of deformation mode, are necessary to describe strains during SPD.  相似文献

The Burgers vector of very close intrinsic dislocations in a near-Σ = 11,{311} grain-boundary in nickel is identified using a geometrical method based on local and accurate measurements of the angular deviation from perfect coincidence Σ = 11 by large-angle convergent-beam electron diffraction and of the dislocation spacing from weak-beam images of the grain boundary.  相似文献
