I defend (metaphysical) ground against recent, unanswered objections aiming to dismiss it from serious philosophical inquiry. Interest in ground stems from its role in the venerable metaphysical project of identifying which facts hold in virtue of others. Recent work on ground focuses on regimenting it. But many reject ground itself, seeing regimentation as yet another misguided attempt to regiment a bad idea (like phlogiston or astrology). I defend ground directly against objections that it is confused, incoherent, or fruitless. This vindicates the very attempt to regiment ground. It also refocuses our attention on the genuine open questions about ground and away from the distracting, unpersuasive reasons for dismissing them. 相似文献

Rats of the Maudsley Reactive and Maudsley Non-reactive strains were given 25 trials of escape-avoidance conditioning after exposure to inescapable shock. Prior shock exposure (PSE) did not affect avoidance or escape latencies, but decreased the number of avoidances made by the Maudsley non-reactive animals and increased the number of their failures to escape. The results are interpreted as demonstrating an interference with the classical conditioning of a conditioned emotional response, through a reduction in the information content of the CS following PSE. The strain differences are interpreted as due to the non-reactive animals being especially sensitive to PSE. 相似文献

The purpose of this study was to test the hypothesis that the duration of episodes of unipolar depression increases with age at onset. On the basis of elevated scores on a self-report depression measure, 2,020 persons were selected from a larger community sample to be interviewed and diagnosed using the Schedule for Affective Disorders and Schizophrenia-Research Diagnostic Criteria procedures. Of the 2,020 persons, 865 had a history of one or more episodes of unipolar depression. The potential effects of the following variables (singly and in interaction) on duration of episode were assessed by means of multiway frequency table analysis and chi-square: age at onset, sex of subject, interval since occurrence of the episode, and type of disorder (major vs. minor depressive disorder). The hypothesis that duration of episodes of depression increases with age at onset was not supported. Women were more likely to have multiple episodes, but did not have longer lasting episodes. 相似文献

ABSTRACT— Popular history films sometimes contain major historical inaccuracies. Two experiments investigated how watching such films influences people's ability to remember associated texts. Subjects watched film clips and studied texts about various historical topics. Whereas the texts contained only correct information, the film clips contained both correct information (consistent with the text) and misinformation (contradicted by the text). Before watching each clip, subjects received a specific warning, a general warning, or no warning about the misinformation. One week later, they returned for a cued-recall test about the texts. Watching a film clip increased correct recall of consistent information relative to recall of the same information when subjects did not see the clip. However, when the information in the film contradicted the text, subjects often (falsely) recalled misinformation from the film. The specific warning substantially reduced this misinformation effect. Teachers should use popular history films with caution and should warn students about major inaccuracies in the films. 相似文献

Processing of identity and position information was investigated in normal and disabled readers at two grade levels (third/fourth grade and sixth grade). Two partial-report tasks were used. The identity task consisted of visual presentation of a five-letter array, followed by a probe letter. Subjects responded yes for a match and no for a mismatch (identity response). The identity + position task was identical except that an additional response was required on correct yes trials: subjects reported the position of the probe letter in the array (position response). Both grade level and reading ability differences were found on the identity response measure, but not on the position response measure. Results were inconsistent with the hypothesis that disabled readers have difficulties in processing order information. Reader ability differences in identity processing attenuated somewhat with age. Serial position functions for both identity and position responses suggested the presence of a left-to-right scanning operation in both age and ability groups. Reader ability differences in processing letter identities were discussed in the context of current theories of reading acquisition. 相似文献
