Recent studies demonstrating that multiple meanings of an ambiguous word are initially accessed even when only one reading is syntactically appropriate with the preceding context can be criticized on at least two grounds. First, many of the syntactic contexts used were not truly restrictive, and, secondly, subjects may not have had time to integrate the context before processing the ambiguous word. In the present study, subjects listened to a sentence ending in an ambiguous word and then made a lexical decision to a target related to either the appropriate or inappropriate reading. Contexts were completely restrictive, and a pause was introduced between the context and the ambiguous word. Multiple access still obtained, providing further support for the claim that lexical access is not guided by syntactic context. 相似文献

This paper reports the operation of robust attentional bias to the top and right during perception of small, single geometric forms. Same/different judgements of successively presented standard and comparison forms are faster when local differences are located at top and right rather than in other regions of the forms. The bias persists when form size is reduced to approximately one degree of visual angle, and it is unaffected by saccadic eye movements and by instructions to attend to other reliably differentiating regions of the forms. Results lend support in various degrees to two of the possible explanations of the bias: (1) a static, skewed distribution of attentional resources around eye fixation; and (2) biased, covert scanning that commences invariably at the top and right of stim ulus forms. Origins of the bias in terms of possible left-hemispheric capacity for constructing representations of visual stimuli from parts, as well as in terms of reading experience and prevailing optic flow during locomotion through space are considered. Recent investigations of conditions under which the bias can be maintained or reduced are mentioned. 相似文献

Evidence for the exchange of parenting information between low-income White mothers and fathers of infants was found. Mothers had more accurate expectations for normative development than fathers, but more accurate fathers had spouses who were also more accurate--even when education was controlled. Though few significant differences were evident in help-seeking behavior when infant problems were encountered, fathers turned to fewer helpers than mothers and were somewhat more likely to rely solely on their spouse. These data indicate that researchers must consider the exchange of information between spouses, particularly when studying the socialization of parenting among fathers at this stage in the life cycle of the family. 相似文献

Earlier versions of this paper were read in the Philosophy department at the University of Helsinki, in the Institute for Advanced Studies in the Humanities at the University of Edinburgh, at Vanderbilt University, at the Indiana Philosophical Association, and at the Institute for Logic and Cognitive Science at the University of Houston. I am grateful for very helpful comments on each of these occasions, and I am especially appreciative to John Haugeland, Mark Johnson, and George McClure for their comments and suggestions. Thanks, too, to Robert Solomon who urged me to amplify my claims about perceptual meaning. 相似文献

A quasi-nonmetric method for multidimensional scaling VIA an extended euclidean model 总被引:1,自引:0,他引:1
An Extended Two-Way Euclidean Multidimensional Scaling (MDS) model which assumes both common and specific dimensions is described and contrasted with the standard (Two-Way) MDS model. In this Extended Two-Way Euclidean model then stimuli (or other objects) are assumed to be characterized by coordinates onR common dimensions. In addition each stimulus is assumed to have a dimension (or dimensions) specific to it alone. The overall distance between objecti and objectj then is defined as the square root of the ordinary squared Euclidean distance plus terms denoting the specificity of each object. The specificity,s
j
, can be thought of as the sum of squares of coordinates on those dimensions specific to objecti, all of which have nonzero coordinatesonly for objecti. (In practice, we may think of there being just one such specific dimension for each object, as this situation is mathematically indistinguishable from the case in which there are more than one.)We further assume that
ij
=F(d
ij
) +e
ij
where
ij
is the proximity value (e.g., similarity or dissimilarity) of objectsi andj,d
ij
is the extended Euclidean distance defined above, whilee
ij
is an error term assumed i.i.d.N(0, 2).F is assumed either a linear function (in the metric case) or a monotone spline of specified form (in the quasi-nonmetric case). A numerical procedure alternating a modified Newton-Raphson algorithm with an algorithm for fitting an optimal monotone spline (or linear function) is used to secure maximum likelihood estimates of the paramstatistics) can be used to test hypotheses about the number of common dimensions, and/or the existence of specific (in addition toR common) dimensions.This approach is illustrated with applications to both artificial data and real data on judged similarity of nations. 相似文献

Subjects were asked to compare the relative depths of two binocular targets embedded in different random dot stereogram backgrounds. The disparities of the background points were either randomized, corresponding to a scattering of points within a volume, or arranged according to a sawtooth (triangle-wave) disparity profile (i.e., a set of slanted planar surfaces separated by sharp depth discontinuities). When the targets were embedded in the random volume, their depths were perceived in accordance with their relative disparities. But when the target points were embedded in the sawtooth surfaces their depths were systematically misperceived in a manner predicted by the incorrect depth interpretation of the background points. Rather than seeing a sawtooth pattern, the background points resembled a staircase in depth, and the targets, which appeared embedded in different steps, were misjudged in depth accordingly. The effect suggests a distinction between the depth processing of isolated binocular features and those associated with continuous surfaces. 相似文献

There is a power to touch, and a magic. Some call it mystery. The purpose of this paper is to reflect on the various meanings and uses of touch, particularly within the context of relationship and helping. There will be no attempt to formulate a protocol for touch or to lay claim to a definitive meaning for touch. Reflection about touch may instead clarify some of its meanings and dynamics while encouraging care providers to embrace the experience of helping-through-touch. This paper supports a considered use of empathie touch because of its power and its ability to embody care. 相似文献

Old-age deficits in the sense of smell as gauged by thresholds, magnitude matching, and odor identification 总被引:2,自引:0,他引:2
Twenty elderly subjects (70-90 years old) and 20 young control subjects (18-24 years old) underwent three kinds of olfactory testing: absolute thresholds to three odorants (d-limonene, iso-amyl butyrate, benzaldehyde), magnitude matching of these odorants to salt tastes, and odor identification of 30 common substances. For all three odorants elderly subjects' mean threshold significantly exceeded that of the young by about ninefold for d-limonene, about threefold for benzaldehyde, and about twofold for iso-amyl butyrate. These threshold differences predict approximate concentration differences necessary to arouse the same estimated odor strength above the threshold for the elderly and the young. Young subjects also scored better than the elderly in odor identification, even when subjects were given four alternatives from which to select the correct label. Unimpaired olfactory functioning is uncommon in the elderly; correlational tests show that as a group the young have better olfactory ability and show more interindividual uniformity. 相似文献

This paper calls for a new approach to the measurement of gender similarities and differences in personality. Critiques of current measures that are based on the measurement of stereotypical masculinity and femininity are reviewed, and an alternative measure is presented. It avoids many of the problems in the other scales by measuring expressiveness and instrumentality in such a way that they are not confounded with variables such as independence or autonomy. Results with this measure in five different samples are presented. These confirm our theoretical definitions of expressiveness and instrumentality, and suggest that only the expressive or relational dimension consistently differentiates samples of women and men.We thank Mary Rothbart for her insightful and constructive comments on an earlier draft; Leisha Sanders, Marcia DeCaro, Vickie Van Nortwick, and Lyn Cogswell for their clerical assistance; the Center for the Study of Women in Society for financial support; and Liza Kuecker and Patricia Gwartney-Gibbs for providing data used in the analysis. An earlier version of this paper was presented at the 1984 annual meeting of the Pacific Sociological Association. 相似文献
