The purpose of this study was to examine moment-by-moment fluctuations in text comprehension processing and determine how and when poor and good comprehenders differ. To do so, we reanalyzed a dataset of think-aloud protocols from 138 intermediate elementary students. Both good and poor comprehenders used a variety of processing strategies when reading text; however, good comprehenders were more strategic in which processes they used than were poor comprehenders. Patterns of two types of poor comprehenders were also analyzed: paraphrasers and lateral connectors. The results indicate that these different reader types not only vary in aggregate but also moment-by-moment processing. 相似文献

Recent research revealed considerable decline in visual perception under low luminance conditions. However, systematic studies on how visual performance is affected by absolute luminance and luminance contrast under low mesopic conditions (<0.5 cd/m2) is lacking. We examined performance in a simple visual discrimination task under low mesopic luminance conditions in three experiments in which we systematically varied base luminance and luminance contrast between stimulus and background. We further manipulated eccentricity of the stimuli because of known rods and cones gradients along the retina. We identified a “deficiency window” for performance as measured by d’ when luminance was < 0.06 cd/m2 and luminance contrast as measured by the luminance ratio between stimulus and background was below < 1.7. We further calculated performance-based luminance as well as contrast efficiency functions for reaction times (RTs). These power functions demonstrate the contrast asymptote needed to decrease RTs and how such a decrease can be achieved given various combinations of absolute luminance and luminance contrast manipulations. Increased eccentricity resulted in slower RTs indicative of longer scan distances. Our data provide initial insights to performance-based efficiency functions in low mesopic environments that are currently lacking and to the physical mechanisms being utilized for visual perception in these extreme environments. 相似文献

Sandra Bem revolutionized psychology with her research on gender, androgyny, and gender schematicity, which culminated in her book, The Lenses of Gender. Her work also provides a model for how to cross inter-disciplinary lines to enhance scholarship and reach political goals. We analyze similarities and differences between Bem’s scholarship and scholarship in queer theory, a theoretical movement in the humanities that analyzes discourses that construct man/woman and straight/gay binaries. There are important overlaps between Bem’s lenses of gender (biological essentialism, gender polarization, and androcentrism) and the ideas of many queer theorists. There are also several interesting differences between Bem’s ideas and queer theory: attention to the intrapsychic processes that make up gender, the extent to which individuals can be liberated from gender, proliferating versus contesting gender, intersectionality, and epistemology and methodology. By assessing the similarities and differences between Bem and queer theorists, we show that the two complement each other, affording a better understanding of gender and sexuality. Additionally, both Bem and queer theory lend insight into feminist and queer activism. The theoretical and political advances that can be made by integrating Bem’s ideas and those of queer theorists serve as examples for why it is worthwhile to cross disciplinary lines. 相似文献

自恋人格个体表现出亲社会行为的减少和对他人的反馈敏感。信任是人类社会互动行为的基础,自恋人格特质可能影响他们的信任决策。为了探究自恋水平如何影响信任博弈中结果评价的大脑活动,本研究采用事件相关电位技术记录了38名被试完成单次信任博弈时的脑电波。行为结果发现相对高自恋者的信任选择率显著低于相对低自恋者的信任选择率。脑电结果表明,相对高自恋者信任损失反馈减互惠获利反馈所得的FRN差异波(d FRN)显著地大于相对低自恋者,并且相对高自恋者结果评价诱发的P300波幅显著地大于相对低自恋者。本研究提供了自恋人格个体信任博弈中结果评价的初步神经电生理学证据。 相似文献

In two experiments, we demonstrate that despite indicating indifference when probed about risk or delay in isolation, when forced to explicitly trade‐off between the two, participants prefer delayed over risky rewards. This pattern of findings sets a boundary condition for any common utility‐based comparison process involving both risk and delay. Furthermore, this change from indifference‐in‐isolation to delay‐preference‐in‐a‐trade‐off strengthens as reward amount increases. Exploratory modeling results suggest that the shift in preference can be explained by allowing for different discount rates for delay‐only choices compared with when delay is in competition with risk. This explanation is better than one in which probability weighting is different between risk‐only choices and risks considered in the presence of a delay. Together, the empirical and modeling work lays a path for future investigations of why and when people's evaluation of the properties of risky and delayed choices vary as a function of the alternatives on offer.

文化混搭指"不同文化在同一时空中呈现"的现象,是全球化背景下心理学中文化研究的新热点。文化混搭研究代表了继跨文化心理学、文化心理学和多元文化心理学之后,心理学文化研究的第四个阶段——文化会聚主义心理学,并从不同方面延伸与拓展了传统的多元文化研究。已有文献从文化混搭对个体心理和行为的影响、个体对文化混搭的反应及心理机制等角度展开了实证研究。未来研究应进一步明晰文化混搭的概念定义和研究范畴、提炼和比较其不同表现形式、探究既有研究结论中的不一致性、比较文化元素的混搭与非文化元素的混搭的异同、采用多学科多层次的研究方法和手段。 相似文献

The hypothesis that cortical cholinergic inputs mediate attentional functions and capacities has been extensively substantiated by experiments assessing the attentional effects of specific cholinotoxic lesions of cortical cholinergic inputs, attentional performance-associated cortical acetylcholine release, and the effects of pharmacological manipulations of the excitability of basal forebrain corticopetal cholinergic projections on attentional performance. At the same time, numerous animal experiments have suggested that the integrity of cortical cholinergic inputs is not necessary for learning and memory, and a dissociation between the role of the cortical cholinergic input system in attentional functions and in learning and memory has been proposed. We speculate that this dissociation is due, at least in part, to the use of standard animal behavioral tests for the assessment of learning and memory which do not sufficiently tax defined attentional functions. Attentional processes and the allocation of attentional capacities would be expected to influence the efficacy of the acquisition and recall of declarative information and therefore, persistent abnormalities in the regulation of the cortical cholinergic input system may yield escalating impairments in learning and memory. Furthermore, the cognitive effects of loss of cortical cholinergic inputs are augmented by the disruption of the top-down regulation of attentional functions that normally acts to optimize information processing in posterior cortical areas. Because cortical cholinergic inputs play an integral role in the mediation of attentional processing, the activity of cortical cholinergic inputs is hypothesized to also determine the efficacy of learning and memory. 相似文献

Sewards and Sewards (2002) argue that while computations necessary for object recognition occur throughout the ventral visual stream, object recognition awareness involves the anterior temporal lobe and the medial orbital prefrontal cortex. The present paper suggests, however, that the medial orbital prefrontal cortex has a unique contribution, namely that of producing a basic experience of a perceptual object. It is further argued that the mechanisms that produce this experience also result in making the object more important than its subparts and features. Finally, it is argued that a reduction in this importance may account for some perceptual difficulties in high-functioning autism. This view is consistent with evidence for early selective abnormalities in other systems involving the medial prefrontal cortex in autism. 相似文献
