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?

Inpatient Multimodal Therapy (imt) is a residential treatment program, lasting a maximum of 36 weeks, for patients with severe neurotic symptoms. A group of
44 chronic obsessive-compulsive patients and a group of 40 chronic phobic patients were treated in order to assess the outcome
and the process of treatment and to identify prognostic factors associated with the effect. At follow-up—on average, eight
months after discharge—it was found that 60% had improved, 32% had remained the same, and 8% had deteriorated, indicating
that, in general, the treatment was beneficial. That these effects were long-lasting is supported by the fact that, at follow-up,
78% of all patients were no longer receiving treatment, 18% were receiving outpatient or day treatment, and 4% were receiving
inpatient treatment. Phobic patients appear to have gained more from the multimodal approach than did obsessive-compulsive
patients, as indicated by the fact that the severity of symptoms decreased as they improved in rational thinking, assertiveness,
and arousal. By contrast, obsessive-compulsive patients relapsed more than phobic patients did. This was attributed to the
fact that the former gained less from the rational-emotive training, denied problems with assertiveness, and did not practice
the acquired relaxation skills. It further appeared that a favorable outcome could be induced in patients who (1) expressed
relatively mild symptoms in this otherwise severe group, (2) reported relatively few additional complaints, (3) could clearly
indicate interpersonal problems, and (4) did not use psychotropic drugs. These prognostic factors are so widespread that not
much weight can be ascribed to them. Yet they are useful for indication ofimt until better predictors are found. 相似文献

This article is based on a review of recent literature on “computing stress”; that is, on the psychological stress effects
of working with computer systems. Current research into the sources of computer-related stress has tended to concentrate on
those employees who operate Visual Display Units (VDUs), either on a full-time professional basis as word-processor (WP) operators,
data-entry clerks, secretaries, or those dealing with enquiries from the public; or employees who use the VDU irregularly
as part of their other duties. A few studies have looked at specific occupation groups, such as printers (Kalimo & Lepp?nen,
1985), information technology professionals (programers and analysts), process workers, and college students (Sproull, Kiesler,
& Zubrow, 1984). Generally, however, research has been carried out on office workers, more often women, carrying out administrative
tasks. An attempt is made to identify those potential work-related stressors that have been isolated by these studies, and
also included are criticisms of the general methodologies used in many of them.
The terms “visual display unit,” “visual display terminal,” VDU, VDT, and “terminal” are used interchangeably. 相似文献

Brief presentations of letter arrays were probed by bar markers within or outside the fovea after various time delays. Figural
information presented to the foveal region was retained better under a photopic condition than information in the parafoveal
region, but under a scotopic condition parafoveal information demonstrated superior retention. However, decay rates over time
of all functions were similar, demonstrating that figural information in the rods and cones decays at similar rates. 相似文献

Traditional strategies for determining whether a reinforcer schedule enhances the occurrence of an activity are reviewed and critically evaluated. A basic assumption underlying these strategies is that it is possible to isolate the effect of reinforcer intermittency on schedule induction. It is concluded that this is not, in fact, possible. An alternative approach is proposed that emphasizes the inductive effects of the reinforcer schedule as a unit and the effects of particular aspects of the reinforcer schedule (e.g., interreinforcer interval, repetition of the reinforcer, reinforcer magnitude). 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

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
