We examined the effects of access modifications to home entrances of people with physical disabilities on their reported community outings. An interrupted time-series design was used, in which the introduction of ramps was staggered across the homes of 6 people with moderate to severe mobility impairments. Four participants reported increases in weekly outings following installation of ramps at their entrances, and 2 reported a small decrease. These findings suggest that reducing the response requirements of access to and from the residence of people with mobility impairments may increase community visits, but may be insufficient given other environmental barriers in the community. 相似文献

Patients with generalized anxiety disorder (GAD) without concurrent depression (n = 11) and normal controls (n = 17) were tested twice, about 2 months apart, on a modified Stroop colour-naming task, which presented anxiety-related, depression-related and neutral words in masked and unmasked exposure conditions. GAD patients received cognitive behaviour therapy in the test-retest interval, and were also retested at follow-up, about 20 months after initial testing. GAD patients showed interference in colour-naming negative words across both masked and unmasked conditions before treatment, but not post-treatment, compared with controls. Reduced interference effects of masked threat words over time correlated with reduced ratings of anxious thoughts at post-treatment, and at follow-up, in GAD patients. Thus, the preconscious bias for threat information in GAD appears to vary over time in association with changes in anxious thoughts and worries. 相似文献

Lesions of the caudate nucleus selectively impair "reference memory" acquisition in the radial maze 总被引:1,自引:0,他引:1
Groups of Long-Evans rats with bilateral lesions of the caudate nucleus, sham lesions, or no lesions were given one trial per day in an eight-arm radial maze. The same four maze arms were baited on each trial. The remaining four arms never contained food. Optimal performance required animals to enter each of the baited arms only once on each trial and to avoid entering the arms in the unbaited set. Rats with caudate lesions learned to enter each of the baited arms only once on each trial. However, these rats were severely impaired in learning to avoid entering the arms in the unbaited set. Implications for dual-memory theories are discussed. 相似文献

An important factor concerning the use of the polygraph in employment settings has been overlooked: How does the polygraph experience affect a new employee's work-related attitudes? In two experiments, subjects were exposed to different hiring scenarios-one included a polygraph examination, the other did not—and then responded to a questionnaire of work-related attitudes. Results indicated that preemployment polygraph examinations may induce negative work-related attitudes. These findings suggest that the polygraph experience acts as a symbolic communication from the employer to the prospective employee, imparting information that may induce feelings of distrust and dislike. Moreover, the polygraph experience may be interpreted by prospective employees as evidence of high levels of employee theft, thus establishing a new (higher) norm of peer theft behavior. 相似文献

The magnitude of the Zöllner illusion was measured as a joint function of the angle of intersection between inducing and test contours and the orientation of the complete display. The intersect angle at which judgmental error was maximal varied as the display was rotated from 0 to 90 deg. An explanation of the Zöllner illusion in terms of selective adaptation of neural orientation specific detectors accounts for the interactive effects of display orientation and intersect angle if it is assumed that different orientation detectors have different tuning characteristics. 相似文献

In multiple-regression analysis of picture-naming latencies from an experiment modelled on Oldfield and Wingfield's (1965), with 94 stimuli and 37 adult subjects, two word frequency measures had insignificant beta weights, while two measures estimating age at which the word was learned had highly significant weights. Objects whose names were learned early were named faster. This result may have important implications for the interpretation of studies using word frequency as a critical variable. It is suggested that word retrieval may be a one-stage process that depends upon the age at which a word was learned. 相似文献

Visual masking between nonoverlapping gratings depends on the similarity of their spatial frequencies. In a metacontrast experiment, bar gratings of 6 and 12 cycles/deg were masked by flanking gratings of various spatial frequencies. For three observers, masking was greatest when the masking frequency was approximately equal to the masked frequency. The results are interpreted in terms of a theory of reciprocal inhibition among frequency-specific neural units. 相似文献
