An implicit assumption in the literature on functional hemispheric asymmetry is that the right hemisphere plays a special role in mental imagery. Using a definition of mental imagery as quasi-perceptual experience, we draw distinctions among visual imagery, visual recognition memory, and visuospatial abilities. We then review the research literature to evaluate the hypothesis that mental imagery is a specialized function of the right cerebral hemisphere, and find that it receives little unambiguous support. Case reports of loss of imagery are no more frequent with right than with left unilateral brain damage. Systematic studies of brain-injured patients provide some support for the hypothesis, but are also consistent with the alternative hypothesis of bilateral representation of imagery. Commissurotomized patients report dreaming and being able to form visual images. Behavioral and psychophysiological studies of non-brain-injured patients either fail to provide evidence in favor of the hypothesis or can be interpreted as compatible with the alternate hypothesis of bilateral hemispheric involvement in imagery. We conclude that there is, presently, insufficient empirical basis for considering imagery a right hemispheric function. We then discuss implications of this conclusion for future research. 相似文献

The relationship between writing hand posture and lateral preference for hand, foot, eye, and ear was examined in a sample of 3709 college undergraduates. A markedly different pattern of lateral preferences was observed in left-handed males and females as a function of hand posture. Left-handed male inverters displayed a tendency toward more leftward lateral preferences in all four indexes; while it was found that hand inversion during writing in left-handed females reflected, if anything, a tendency toward more rightward lateral preferences. 相似文献

A face-recognition task involving monocular presentation of laterally displaced stimuli yielded a nasal hemiretinal advantage for reaction time for correct identifications, but a temporal hemiretinal advantage for accuracy (d'). These hemiretinal effects, in conjunction with eye dominance, could in principle distort or obscure interpretations of hemispheric processing differences obtained with binocular stimulation. 相似文献

Mismatching in negotiation involves responding with high demands to the opponent's low demands and with low demands to the opponent's high demands. Prior research has shown that the opponent's demands are often mismatched but that this effect is attenuated when information is available about the outcomes achieved by the opponent from the available alternatives. The present research showed that mismatching was also attenuated when the negotiator knew the location of the opponent's limit (the alternative beyond which the opponent would not concede). Two new interpretations of the attenuation effect were suggested on the basis of this finding. In addition, women were found to engage in more mismatching than men, being particularly likely to exploit a soft opponent. 相似文献

After viewing an aggressive, sexually aggressive, erotic heterosexual, or control film, 129 females and 135 males expressed their willingness to help and hostility toward the male or female experimenter. Males extended the least help to the experimenter following the aggressive film and expressed more positive affect than females. Erotophilic males expressed slightly less hostility toward a female than a male experimenter. Erotophiles expressed more positive attitudes toward women and toward men after viewing either the rape film shown by a male experimenter or the erotic film shown by a female experimenter, compared to erotophobes. Among erotophobes, these two experimental conditions generally produced the most negative effects on general attitudes about the sexes. Affective responses to sex variations in dominant status and to aggressivity were employed to provide explanations for these results. 相似文献

Given that mythmakers must construct stories that are comprehensible to their audience, it is reasonable to expect stories to be conceptually natural even when their topics deal with the supernatural. Thus, as stories are adapted to human conceptual structure, they should reflect characteristics of that structure. An examination of the types of magical transformations in Ovid's Metamorphoses and Grimms' Fairy Tales suggests that this is the case. It was possible to predict the patterns of transformations on the basis of structural properties of ontological knowledge, which is knowledge of the basic categories of existence (e.g., conscious beings, animals, plants, events). Other characteristics of the transformations seem to reflect the conceptual distinction between animates and inanimates as well as the relative prototypicality of various taxonomic classes of animals. It appears that aspects of conceptual structure can constrain patterns of thinking even during “the willing suspension of disbelief.” 相似文献
