The evidence pointing to the retinal origin of after-images is considered. The reports of the occurrence of after-images from visual images of hallucinatory vividness are reviewed.
Experimental results are presented to indicate that a complementarily coloured afterimage may arise following the exposure of the temporarily blind retina to a coloured stimulus.
After-images, or after-effects, from vivid images are described in seventeen persons (mostly possessors of “number-forms”). They are found to move with the eyes and to show, in some persons, a degree of conformity with Emmert's Law which, while considerable, is less than that of after-images of real stimuli. In the case of one “eidetic” subject, the after-images from neither real nor imaged stimuli conformed with Emmert's Law. In some persons, after-images of images occur in complementary colours.
The retinal origin of after-images is affirmed, but that they can occur occasionally as a purely central phenomenon is acknowledged. The possible learned or inherent nature of after-images of central origin is discussed. 相似文献

Disproportionate Representation in Special Education: A Synthesis and Recommendations 总被引:2,自引:0,他引:2
Disproportionate representation of minority students in special education remains a very controversial, unresolved issue. This synthesis summarizes historical perspectives and current knowledge about disproportionate representation with respect to: (a) definitions of disproportionate representation and related issues of interpretation; (b) national and state-level estimates of disproportionality for four ethnic groups; (c) legal, policy, research and teacher education responses to disproportionality; and (d) hypothesized causes and predictors of disproportionality. Authors stress the need for: coherent and well-articulated conceptual frameworks, responsible use and representation of data, research dialog that is informed by appreciation of the complex sociopolitical history and current context, and the need for effective advocacy to improve the educational success of minority students. 相似文献

We applied the moral dissonance reduction framework, used to explain the maintenance of a positive self-concept in dishonest behavior, to understand self-justification of prejudice. Participants identified ambiguously negative intergroup behaviors, then evaluated those behaviors when performed by others and themselves. As predicted by moral dissonance reduction, participants were less critical of their own behavior when considering others’ behaviors before their own. In a third study directly comparing prejudiced and dishonest behavior, participants’ responses showed the greatest self-justification in the initial question about their behavior regardless of the content of the question, whereas subsequent questions showed more stability, consistent with the idea that participants adjusted their initial self-reports to avoid damage to their self-concepts. 相似文献

Previous research has shown that HIV stigma in India can be characterized by a framework dividing manifestations into enacted (discrimination), vicarious (hearing stories of discrimination), felt normative (perceptions of stigma's prevalence), and internalized stigma (personal endorsement of stigma beliefs). We examined whether this framework could explain associations among stigma, efforts to avoid HIV serostatus disclosure, and depression symptoms in a cohort of 198 HIV-infected individuals from Southern India who were followed up for one year as part of a study of antiretroviral adherence. Prior studies had suggested that disclosure avoidance was a primary outcome of stigma and that impaired well-being was a primary outcome of disclosure avoidance. Analyses from our longitudinal research revealed that the pattern of associations among stigma, disclosure avoidance, and depression symptoms remained consistent over time. Enacted and vicarious stigmas were correlated with felt normative stigma beliefs. In turn, felt normative stigma was correlated with disclosure avoidance. And, enacted stigma, internalized stigma, and disclosure avoidance were all associated with depression symptoms. However, even though the overall framework held together, internalized stigma and depression symptoms dropped significantly over time while other components remained unchanged. These findings suggest that, although HIV stigma may limit disclosure, it does not invariably lead to psychological maladjustment. Amidst ongoing perceptions and experiences of stigma, HIV-positive individuals can achieve significant improvements in their acceptance of the disease and in mental well-being. 相似文献

Linear regression analysis is one of the most important tools in a researcher’s toolbox for creating and testing predictive
models. Although linear regression analysis indicates how strongly a set of predictor variables, taken together, will predict
a relevant criterion (i.e., the multiple R), the analysis cannot indicate which predictors are the most important. Although there is no definitive or unambiguous method
for establishing predictor variable importance, there are several accepted methods. This article reviews those methods for
establishing predictor importance and provides a program (in Excel) for implementing them (available for direct download at
. The program investigates all 2
p
– 1 submodels and produces several indices of predictor importance. This exploratory approach to linear regression, similar
to other exploratory data analysis techniques, has the potential to yield both theoretical and practical benefits. 相似文献

Anxiety is a common co-occurring problem among young people with autism spectrum disorders (ASD). Characterized by deficits
in social interaction, communication problems, and stereotyped behavior and restricted interests, this group of disorders
is more prevalent than previously realized. When present, anxiety may compound the social deficits of young people with ASD.
Given the additional disability and common co-occurrence of anxiety in ASD, we developed a manual-based cognitive-behavioral
treatment program to target anxiety symptoms as well as social skill deficits in adolescents with ASD [Multimodal Anxiety
and Social Skills Intervention: MASSI]. In this paper, we describe the foundation, content, and development of MASSI. We also
summarize data on treatment feasibility based on a pilot study that implemented the intervention. 相似文献

The relationship between objective and perceived fit with academic major, adaptability, and major-related outcomes 总被引:2,自引:0,他引:2

This study examined the effects of fit with college major on major commitment, GPA, college satisfaction, and changing one’s major. We further examined how individual adaptability may moderate the importance of fit on these outcomes. College students (N = 198; 160 women and 38 men; mean age = 19.14 years) completed an interest inventory used to assess objective fit with major, and also indicated their perceived fit with major. Results revealed little correlation between perceived fit and objective fit, with differential relationships to these outcomes. Perceived fit showed stronger positive correlations with affective major commitment and academic self-efficacy than did objective fit. Regarding the moderating role of adaptability, individuals higher in adaptability reported higher institutional satisfaction when there was lower perceived fit. Adaptability also had a main effect on major-related outcomes above and beyond the effects of fit. Practical and theoretical implications of these results are discussed. 相似文献

The paper discusses one of the central arguments in Dennett’s Freedom Evolves, an argument designed to show that a deterministic universe would not necessarily be a universe of which it could truly be
said that everything that occurs in it is inevitable. It suggests that on its most natural interpretation, the argument is vulnerable to a serious objection. A second interpretation
is then developed, but it is argued that without placing more weight on etymological considerations than they can really bear,
it can deliver only a significantly qualified version of the conclusion that Dennett is seeking. Moreover, the new argument
depends upon an intermediate conclusion which, on the face of it, looks to be self-contradictory. Dennett is able to avoid
the appearance of self-contradiction only by utilising a possible-worlds framework for the understanding of “could have done
otherwise” judgements which is argued to be unsatisfactory. It is suggested that a different framework might hold the key
to understanding how better to defend these same judgements from purported threats from determinism. 相似文献

Previous work in our laboratory demonstrated that galantamine, a cholinesterase inhibitor and weak cholinergic agonist, facilitated classical trace eyeblink conditioning in healthy, young rabbits [Simon, B. B., Knuckley, B., & Powell, D. A. (2004). Galantamine facilitates acquisition of a trace-conditioned eyeblink response in healthy, young rabbits. Learning & Memory, 11(1), 116-122.]. The current study investigated the effects of galantamine (0.0 or 3.0mg/kg) in rabbits sustaining knife-cut lesions to the fimbria-fornix, a major projection pathway connecting the hippocampus to cortical and subcortical brain structures involved in the formation of long-term memories. Two experiments were conducted. Experiment one assessed the effects of knife-cut lesions to the fornix or sham surgeries on trace eyeblink (EB) conditioning. Results indicate that fornix lesions significantly retarded EB conditioning when trace parameters were employed. Experiment 2 assessed whether treatment with galantamine would reverse the deficits caused by fornix damage. Results indicate that 3.0mg/kg GAL reversed trace EB conditioning deficits in animals with fornix knife-cut lesions. These findings suggest that galantamine may provide benefit in the reversal of cognitive dysfunction following certain types of brain damage, especially damage involving hippocampal structures. 相似文献
