A time-sharing paradigm was used to study potential interference effects of concurrent successive-auditory/vocal, successive-visual/motor, simultaneous-auditory/vocal, and simultaneous-visual/motor tasks on right- and left-handed manual-motor behaviors of differential levels of difficulty. Participants were selected from each of three developmental levels from 9 through 20 years of age. Results suggested that processing style (i.e., successive or simultaneous) interacts with modality (i.e., auditory/vocal or visual/motor) in terms of lateralized interference effects; however, potential effects due to age level were obfuscated by differential concurrent-task difficulties. 相似文献

Improvement in auditory-successive selective attention was noted across the age range of 9 through 16 yr. In contrast to comparable paradigms with visual-simultaneous materials, 30 learning disabled and 30 normal boys did not differ. Results of research on selective attention may be affected by task materials and encoding requirements. 相似文献

The contents of 800 singles ads were examined. They were compared by the gender of the advertiser, the year of appearance (1991 and 1986), and the SES of the target readership (affluent and general). There were very few advertisers who listed themselves as black, so these ads were not included in the study. Gender differences were most important. Men were more likely to offer financial security and seek attractiveness. Women were more likely to offer attractiveness and seek financial security. The gender differences were in agreement with those reported for over a decade and from many geographical areas, although less than half of the advertisers mentioned either finances or attractiveness. Contrary to our hypotheses, the contents of mens' and womens' ads were more different in 1991 than they had been in 1986 and more in conformity with sexual stereotypes. Ads in a paper with an affluent readership were more likely to mention educational and financial status while ads in a paper with a readership throughout the metropolitan area were more likely to mention physical characteristics. 相似文献

Mental disability claims for workers' compensation are troublesome for courts and clinicians. The overall pattern is one of a chaos of state legislative and judicial restrictions on recovery. A notable exception to this chaos is the use in the majority of American jurisdictions of the uniform system for determining mental impairment contained in the American Medical Association's Guides to the Evaluation of Permanent Impairment. The use of the Guides seems to have promoted uniformity among jurisdictions and greater acceptance of mental disability claims. A new problem with the Guides may lay ahead as the courts try to apply the third edition. This recent revision does not contain a percentage rating system for mental impairment. The availability of this system, and in the first edition of a diagnostic system, has long been attractive to courts, although it has undermined the AMA's goal of objective evaluation. 相似文献

The interrelationship of measures of rigidity-flexibility and of psychometric intelligence is examined. The latent factors of Attitudinal Flexibility, Motor-Cognitive Flexibility, and Psychomotor Speed are derived from the Test of Behavioral Rigidity, and factors of Inductive Reasoning, Spatial Orientation, Verbal Ability, Numeric Ability, Verbal Memory, and Perceptual Speed are derived from the Thurstone Primary Mental Abilities Test and the Educational Testing Service Kit of Factor-Referenced Tests. The data base in this study comes from the fifth wave of the Seattle Longitudinal Study (N = 1,628; age range, 22-95 years). The Rigidity-Flexibility factors were found to be independent of the cognitive domain. Also, longitudinal stability of the factor structure of the rigidity-flexibility domain was confirmed for 837 participants tested in both 1977 and 1984. 相似文献

The editors of the JRE solicited short essays on the COVID-19 pandemic from a group of scholars of religious ethics that reflected on how the field might help them make sense of the complex religious, cultural, ethical, and political implications of the pandemic, and on how the pandemic might shape the future of religious ethics. 相似文献

We used fMRI to examine patterns of brain recruitment in 22 healthy seniors, half of whom had selective comprehension difficulty for grammatically complex sentences. We found significantly reduced recruitment of left posterolateral temporal [Brodmann area (BA) 22/21] and left inferior frontal (BA 44/6) cortex in poor comprehenders compared to the healthy seniors with good sentence comprehension, cortical regions previously associated with language comprehension and verbal working memory, respectively. The poor comprehenders demonstrated increased activation of left prefrontal (BA 9/46), right dorsal inferior frontal (BA 44/6), and left posterior cingulate (BA 31/23) cortices for the grammatically simpler sentences that they understood. We hypothesize that these brain regions support an alternate, nongrammatical strategy for processing complex configurations of symbolic information. Moreover, these observations emphasize the crucial role of the left perisylvian network for grammatically guided sentence processing in subjects with good comprehension. 相似文献

Comparing contrast-modulated and luminance-modulated masking: effects of spatial frequency and phase
The masking of a sinusoidal test grating by contrast-modulated (CM) gratings could, in principle, be attributable to the presence of a distortion product, injected into the stimulus during some nonlinear transformation at an early level of visual processing (e.g. Nachmias, 1989 Vision Research 29 137-142). If so, CM gratings and luminance-modulated (LM) gratings of similar effective contrast and spatial frequency should mask the detection of sinusoids in a similar fashion. We compared the effects of masking by 1 cycle deg-1 CM gratings [both simple beats (8 + 9 cycles deg-1) and amplitude-modulated gratings (8 + 9 + 10 cycles deg-1)], with those of masking by 1 cycle deg-1 LM gratings of low contrast. We found that: (i) CM and low-contrast LM grating masks yielded similar spatial-frequency tuning functions around the modulation frequency of 1 cycle deg-1; (ii) low-contrast LM gratings masked the detection of test sinusoids in a highly phase-dependent fashion, while masking by CM gratings did not vary systematically with relative spatial phase. The results suggest that masking produced by CM gratings cannot simply be explained by the presence of a distortion product at the beat or modulation frequency. 相似文献
