To what extent does the reader integrate visual information from one fixation to the next and derive a spatially extended representation of text? Experimental studies of transsaccadic fusion in reading produce conflicting evidence. The results from work on “stepped-text” presentation, in which words appear in a single physical location, have been used to argue that readers secure no advantage from the spatially extended page and that reading may proceed without the computation of spatial coordinates. It is suggested that this conclusion may be inaccurate. A processing decrement is found for materials above a critical level of complexity when presented in a “stepped” mode. This appears to derive from the reader’s need at times to reinspect parts of previously presented text. Reinspections of this kind, which appear to characterize the fluent reader, demand a degree of spatial coding. Two classical issues in the study of perception come together in the study of reading. First, what segments the continuous stimulus flux into discrete perceptible objects? The second is, what is the nature of the control system for eye movements? - Kolers (1983) This research is supported by a grant from the Economic and Social Research Council.  相似文献

This study evaluated the relative efficacy of long (1 minute) and short (15 seconds) durations of negative practice for reducing self-stimulatory leg pounding of a traumatically brain-injured adult. In individual social skill training classes, long negative practice and short negative practice were administered concurrently in an alternating treatments design. Generalization of treatment effects outside of training sessions was assessed during the client's lunch period. The results revealed that both durations of negative practice were equally effective in reducing leg pounding during training sessions. However, the effects of training did not generalize to settings in which the practice contingency was not enforced. Pounding was more frequent and negative practice somewhat less effective during periods of high social stimulation.  相似文献

The present authors address the need for specialized professional training for psychologists who primarily work with the problems of childhood. It is argued that the area of child psychology is an amalgam of selected components of developmental, educational, and clinical psychology, and further that it is sufficiently discrete to warrant specialized training programs for child psychologists. Questions concerning the particular content of such training, and the level at which the training should take place, are raised. Various options regarding the answers to these questions are discussed, and a specific recommendation is presented.  相似文献

The performance of poor and normal sixth-grade readers was compared on an auditory short-term memory task in two studies. In the first study, the effects of distraction, list length, and speed of stimulus presentation were investigated to test the hypothesis that the performance of the poor readers is affected by deficits in selective attention. Group differences in performance, however, were obtained for both distraction and no-distraction conditions. The second experiment examined the hypothesis that group differences may reflect differences in the use of rehearsal. In the second experiment, half the reading-disabled children and half the controls were provided with rehearsal training prior to completing the same short-term memory task a second time. Rehearsal training resulted in improved performance relative to children who were not trained; however, there was no rehearsal training x reading group interaction. The poor readers continued to show deficits in performance relative to the performance of control children. The results of these two studies suggest that deficits observed for poor readers on short-term memory tasks may reflect processing difficulties in some area that precedes rehearsal and affects performance under both distraction and no-distraction conditions.The authors wish to express their thanks to the Sachem School District and Betty Gould, Nicholas Opinanate, and Guy Barber for their unlimited cooperation, and to John Neale for very helpful discussions of a number of issues in this paper.  相似文献

P. E. Spector's (1982, Psychological Bulletin, 91, 482–497) hypothesis that under conditions of freedom of choice persons characterized by an internal locus of control will experience greater satisfaction with an undesirable task than persons characterized by an external locus of control is considered in light of distinctions between perceived control and perceived choice. Perceived choice is proposed as an intervening variable implicit in Spector's argument. This reasoning was tested with 46 male and female college student participants in a 2 (Choice) × 2 (Locus of Control) factorial design experiment. An interaction of Choice × Locus of Control on task satisfaction was obtained such that internals tended to be more satisfied when given a choice while externals experienced greater satisfaction when not given a choice. The implications of this result for Spector' hypothesis and for the manner in which undesirable work is assigned are discussed.  相似文献

Research investigating social values in interdependency situations has generally demonstrated age differences across the 5- to 10-year-old age range. However, the precise nature of these differences is unclear. Further, the differences in the social values of adults and children has not been addressed. The present study examined the social values of undergraduates and children using a measurement technique designed to allow an accurate inference of social values. Ninety-one 6- to 10-year-old children and 100 undergraduates rated the desirability of a set of outcomes which systematically varied with regard to the benefits to themselves and another person. Theoretically specified characteristics of the outcomes were then used to generate a regression equation predicting the desirability ratings separately for each individual. These regression equations were then clustered into groups of individuals who used decision rules characteristic of the major social values. The results indicate that the 8- to 10-year-old children, compared to the 6- to 7-year olds, more often expressed a social value involving equality and tended to less often express a social value involving superiority. Comparison of the social values expressed by the children and adults indicated that the adults more often expressed group-enhancement and individualism social values and less often expressed a social value involving superiority.  相似文献

ABSTRACT Because of the existence of severely defective humans it is commonly held that whatever consideration is due to all humans is also due to many other animals, and that therefore speciesism, or the readiness to prefer the interest of humans to those of other animals, is unjustified. After criticism of this reasoning a 'naturalised' speciesism, acknowledging, for example, the affinities between species, is articulated and defended. A key to this defence is the separation of the task of specifying morally significant differences between humans and other animals from the task of justifying the extension of consideration to defective humans. The conclusion is that more traditional vices than speciesism are chiefly to blame for the shabby treatment of animals by humans.  相似文献
