Two studies of college undergraduates (ns = 95 and 92, primarily non-Hispanic whites and Asian Americans) investigated gender stereotypes of stress and emotion, as
well as variables that influence the perception of gender-related differences. Study 1 assessed how gender stereotypes differ
from the self-reports of men and women. When asked to choose a label for the subjective experience of the average man and
the average woman in a series of problematic hypothetical situations, participants generally tended to believe that the average
female would feel ‘emotional,” but that the average male would feel “stressed.” By contrast, the label participants chose
to describe their own subjective experience was not significantly affected by their gender. In addition, participants believed
the average woman and man differed more in the intensity of their emotions than in the intensity of their stress, a belief
contradicted by their own self-reports. Results of Study 2 indicated that gender-related differences in estimations of stress
and emotion for the self were reduced or eliminated when specific information about experience-eliciting situations was provided.
We would like to thank Matthew Dank for his help in preparing the stimulus materials. 相似文献

Two experiments addressed whether response latency in a trial of the lexical decision task is independent of the lexical status of the item presented in the previous trial. In Exp. 1, it was found that both word and nonword responses were significantly slower when the previous trial had involved a nonword than when it had involved a word. In Exp. 2, which employed a different list composition, it was found that responses to nonwords and pseudohomophones were significantly slower when the previous trial had involved a nonword or a pseudohomophone than when it had involved a word. However, responses to words were not influenced by the nature of the previous trial. We concluded that sequential dependencies exist across consecutive trials in the lexical decision task even when there is no semantic, morphological, phonological, or orthographic relationship between the items presented during those trials. 相似文献

Although Michael Polanyi's model of science and his construal of the nature of the real are usually thought to be congenial to religion and although Polanyi himself says that "the stage on which we thus resume our full intellectual powers is borrowed from the Christian scheme of Fall and Redemption" (Polanyi 1958, 324), theologians have given little attention to the model of God he presents. The metaphysical and theological vision unfolded in part 4 of Personal Knowledge is a thoughtful alternative to materialist versions of neo-Darwinism and provides a platform for revisiting four long-standing controversies at the interface of science and religion: whether life and mind can be completely specified in terms of physical analysis, whether nature can be adequately understood without appeal to final causes, whether natural selection adequately explains life's diverse forms, and whether knowledge can be fully objectified. Through an exploration of Polanyi's contribution to these discussions, we undertake to show not only that his treatment of God as a cosmic field is strikingly original but also that in reinstating activity as a metaphysical category, he reconstructs our understanding of our creaturely hope and calling. 相似文献

FLUCTUATIONS IN THE TIME REQUIRED FOR ELEMENTARY DECISIONS 总被引:1,自引:0,他引:1

Abstract— The nature of reaction time variability is analyzed in a suite of four experiments involving tasks, methodologies, and types of perceptual judgment commonly encountered in cognitive psychology In every case, a substantial fraction of the trial-by-trial variability in reaction time latency is shown to be well described by a particular type of fluctuation known as l/f noise. These results suggest that the time it takes to make and register a speeded decision reflects a kind of dynamic complexity that is seen in natural systems that self-organize at the boundary between order and chaos. 相似文献

Abstract— This article argues that the greatest progress in developing more effective psychotherapist will come from a renewed emphasis on designing and conducting therapy research as basic science devoted lo the acquisition of cause-and-effect relationships and from collaborations between clinical researchers and basic researchers from other domains of psychology. 相似文献

How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation. 相似文献

Has suffering become an ugly word in the normalization debate? Are the disabled and their families forced into a Pollyanna 1 1 Pollyanna is the heroine in Eleanor Porter's book (1913), which has since been published in countless editions. Pollyanna received a pair of crutches when all she wanted was a doll. Because she didn't need to use her crutches, she was so happy that she played “being-happy” games for the rest of her life.
culture in order to be acknowledged and accepted in good company as the worthy disabled? This essay poses a controversial question: I would like to start a debate and ask whether normalization also has an unseen, ideological downside. 相似文献

Mechanical restraints are commonly used to reduce the risks associated with severe self-injurious behavior (SIB), but may result in movement restriction and adverse side effects (e.g., bone demineralization). Restraint fading may provide a method for decreasing SIB while increasing movement and reducing these side effects. In the current investigation, rigid arm sleeves and restraint fading (gradually reducing the rigidity of the sleeves) were used with 3 clients who engaged in hand-to-head SIB. Restraints and fading reduced the hand-to-head SIB of all clients. However, for 1 client, the addition of a water mist procedure further reduced SIB to near-zero levels. For a 2nd client, another form of SIB developed that was not prevented by the rigid sleeves. For a 3rd client, a topography of SIB that was not physically prevented by the rigid sleeves was also reduced when restraints and fading were introduced. 相似文献
