Keith Graham 《Argumentation》2001,15(4):471-487
A problem arises, both for philosophy and for argumentation theory, in a pluralist world where people hold widely different beliefs about what to do. Some responses to this problem, including relativism, might settle but do not provide any criteria for resolving such differences. Alternative responses seek a means of resolution in universalist, culture-neutral criteria which must be invoked in assessing all human action. A philosophically adequate account of universalism would contribute to an ideal of critical rationality, as well as to the ideas of field-invariance and of convincing, as opposed to persuasive, argumentation. The account's adequacy would require universality both in form and in content. Universality in form is secured by seeking universal preconditions for practical reasoning in general, rather than specifically for morality. Universality in content is harder, and candidates such as freedom, autonomy and health are problematic. An alternative content is provided by the proposition that the satisfaction of material preconditions is necessary for the performance of any action whatever. Neglect of these preconditions may constitute a fallacy in the extended sense found in argumentation theory, and assumptions about them should form part of the point of departure for any practical deliberation. 相似文献

This article describes the development and initial validation of the Infrequency-Psychopathology scale, Fp-A, for the MMPI-A (Butcher et al., 1992). The scale parallels the Infrequency-Psychopathology scale, F(p), that has been developed for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). Results demonstrated that the 40-item Fp-A scale is superior to the F scale at discriminating between faking-bad and accurate reports of psychopathology, although the improvement over F was modest, particularly when compared to the improvement found for the F(p) scale. The difference seemed to reflect the superiority of the MMPI-A F scale to the MMPI-2 F scale. Even so, the findings suggest that the identification of overreporting on the MMPI-A could potentially be enhanced by using Fp-A as an adjunct to the F scale. 相似文献

Separate roles for executive and phonological components of working memory in mental arithmetic 总被引:13,自引:0,他引:13
A dual-task methodology was used to investigate the roles played by executive and phonological aspects of working memory in mental arithmetic. Experiment 1 showed that suppression of articulation impaired the ability to add a pair of briefly presented three-digit numbers. Suppression had no effect when the need to store temporarily was minimized by making the numbers visible throughout calculation. Experiment 2 showed that disrupting executive processes by requiring concurrent performance of a Trails task impaired the ability to add numbers that remained permanently visible. Performance on the Trails task deteriorated as the number of carry operations in the addition increased. Experiment 3 showed that this decline in Trails performance was not simply due to the extra time taken by carrying. These and other features of the results suggest that the carrying component of mental arithmetic places substantial demands on executive processes, whereas the need to retain problem information is met by the phonological loop. The results are consistent with an interpretation of executive processes according to which there is a limit on the capacity to inhibit strongly primed routine operations. 相似文献

On the interpretation of working memory span in adults 总被引:2,自引:0,他引:2
Experimental research into children's working memory span has shown that retention duration contributes substantially to span performance, while processing efficiency need not be related to concurrent memory load (Towse, Hitch, & Hutton, 1998). These findings have been used to argue for a model of working memory span that emphasizes time-based forgetting rather than the popular resource-sharing or tradeoff framework. The present paper considers whether adults perform working memory span tasks in a qualitatively different way. Data from reading span and operation span tasks show that adults' performance can be distinguished from that of children, but also that a task-switching model of working memory span can explain some important aspects of performance. 相似文献

An experiment was performed in which ten subjects made comparative judgements of two objectively equally long movement lengths. Additional movements, known as anchor movements, occured before, between, or after the comparison pair in order to decide whether such anchor movements would operate proactively (i.e., producing an effect on the reception of the subsequent stimulus) or retroactively (i.e., affecting the memory trace of the preceding stimulus). The results are interpreted to mean anchor movements act retroactively. 相似文献

Effects of attending selectively to the spatial position of reflex-eliciting and reflex-modulating stimuli 总被引:2,自引:0,他引:2
S A Hackley F K Graham 《Journal of experimental psychology. Human perception and performance》1987,13(3):411-424
The question of whether automatic, sensory processes can be modified by selectively directing attention to stimuli was addressed by comparing effects on brainstem reflexes that share a common efferent pathway but have distinct afferent limbs. Subjects judged the duration of brief but intense blink-eliciting tones (Experiment 1) or weak tones preceding a blink-eliciting air puff at interstimulus intervals producing blink inhibition (Experiment 2). Tones occurred unpredictably at left, right, or midline loci; designation of the target location varied across blocks of trials. Latency of blinks to lateralized blink-eliciting targets was facilitated selectively, and the magnitude of blinks evoked by air puff following lateralized prestimulus targets was inhibited selectively. There was no evidence for a midline selective effect. Results appear to support a preset differential processing of stimuli in sensory pathways at low, possibly subcortical, levels and the consequent modification of obligatory, automatic processes. 相似文献

Visual and phonological components of working memory in children 总被引:1,自引:0,他引:1
Previous studies have shown that young children's immediate memory for a short series of drawings of objects is mediated by a visual component of working memory, whereas older children rely chiefly upon a phonological component. Three experiments investigated the hypothesis that older children rely also, but to a lesser extent, on visual working memory. Experiment 1 confirmed previous evidence that 11-year-olds' memory is disrupted by phonemic similarity of object names, but is unaffected by visual similarity of the objects themselves. However, when articulatory suppression was used to prevent phonological coding, levels of recall were sensitive to visual rather than phonemic similarity. Experiment 2 compared the effects of interpolating an auditory-verbal or a visual postlist task on memory for drawings viewed either with or without suppression. The visual task had a clear disruptive effect only in the suppression condition, where it interfered selectively with recall of the most recent item. Experiment 3 compared the effects of interpolating an auditory-verbal or a mixed-modality (visual-auditory) postlist task when subjects were not required to suppress. There was greater interference from the mixed-modality task, and this effect was confined to the last item presented. These experiments are taken as confirming the presence of a small but reliable contribution from visual memory in 11-year-old children's recall. As in younger children, visual working memory in 11-year-olds is sensitive to visual similarity and is responsible for a final-item visual recency effect. The results also show that older children's use of visual working memory is usually masked by the more pervasive phonological component of recall. Some implications for the structure of working memory and its development are discussed. 相似文献
