Evidence suggests that for close retinal areas a correlation in sensitivity exists between the areas. Correlations as a function of distance from fixation and between areas were studied. In Experiment I, both forms were equidistant from fixation and five different distances apart. In Experiment II, both forms fell on an imaginary line through fixation. The forms usually did not fall on equally sensitive areas as in Experiment I. Both experiments showed that accuracy was lower for two- than for one-form displays. Closer forms had the lowest accuracy, suggesting perhaps mutual contour masking. However, in the sense of an intratrial correlation, no significant relationships were found. These two types of independence were discussed in terms of contour masking and varying sensitivity. 相似文献

Sickle cell disease (SCD) occurs in 1 of every 400 to 500 African American births. Despite its prevalence, there has been a relative dearth of attention paid to SCD in the psychological literature. African American SCD adolescents and young adults, individuals at an already vulnerable developmental stage, are at increased risk for psychological distress and psychosocial impairments (e.g., depression and low self-esteem, poor social and academic/vocational functioning). Such difficulties often result in problematic adherence to medical regimens, and thus represent a potentially serious clinical and public health problem that merits the attention of psychologists working in medical settings. This article (1) reviews the psychosocial needs peculiar to SCD patients transitioning from adolescence to young adulthood; (2) applies a culturally informed stress-coping-adjustment framework to assess and address the psychological status, psychosocial functioning, and disease outcomes of these individuals; and (3) describes a culturally and developmentally sensitive, psychoeducational group intervention. 相似文献

Synchronous coordination between two body segments departs from phase locking at 0 or pi radians when the segments are asymmetrical. In models of coordination dynamics, this detuning is typically quantified by Deltaomega = (omega1 - omega2), where omega1 and omega2 are the uncoupled frequencies of the two segments. An experiment is reported in which the magnitude of Deltaomega not equal 0 was satisfied by different ratios Omega of omega1 and omega2. The degree of detuning was found to vary systematically with Omega and Deltaomega. This result corroborates previous research using the complementary manipulation of varying Deltaomega for a fixed Omega. A challenge for future dynamical modeling is identifying precisely how the detuning quantity incorporates both the absolute and relative differences in the. uncoupled segmental frequencies. 相似文献

Relaxation training has typically been discussed as a singular procedure to be used as a therapeutic treatment technique for a wide variety of disorders. A review of the empirical literature from 1970 to 1979 is provided with an emphasis on clinical populations utilized, dependent measurement and procedural variability and lack of standardization with respect to relaxation procedures. Suggestions for future research are made which emphasize systematic evaluations of treatment components, target problems and criterion behavior change. 相似文献
