The resolution of lexical ambiguity was studied in two experiments. While subsequent selection would appear to limit longer term storage to one meaning of an ambiguous word, multiple initial encoding of homophones and homographs was indicated by the intrusion of their alternative meanings across trials in a Brown-Peterson paradigm. In Experiment 1 subjects heard four words and then engaged in a 10osec distractor task. Written recall was then demanded. On context trials a homophone with two distinct alternative meanings was presented with other words biasing either a dominant or subordinate meaning, for example, look, stare,peer, glance. On the next trial words related to an alternative meaning were presented, for example, dock, wharf, quay, jetty. Intrusions of the graphic forms of alternative meanings le.g.,PIER) into critical trial recall occurred whether the dominant or subordinate meaning of the homophone had been biased by context. Experiment 2 employed visual presentation of homographs, for example, GOLD, IRON,LEAD, and oral recall, but was logically similar to Experiment 1. Intrusions of the alternative codings of homographs across trials again occurred, for example, GUIDE, DIRECT,lead, regardless of the meaning originally biased by context. 相似文献

The interactive similarity ordering (ISO) system gathers similarity data that can be symmetric, asymmetric, or rectangular in form. Because the subject makes a very simple judgment and the number of judgments is interactively minimized, this procedure can be used for a relatively large number of stimuli. This system has been programmed on a PDP-11/45 and on a Motorola 6800-based microprocessor. An empirical investigation indicates that the ISO system compares favorably with other large stimulus set procedures. 相似文献

If a weak tone precedes an intense tone, then the acoustic startle eyeblink reflex elicited by the stronger stimulus is inhibited. It has been suggested that the leading stimulus gives rise to a protective middle ear reflex that attenuates the effective intensity of the second. This hypothesis was tested and disproved. In seven subjects intense tone bursts sufficient to elicit both intratympanic and eyeblink responses were presented sometimes alone and sometimes preceded at various lead times (25 to 400 msec) by a weak tone. The weak tone inhibited the amplitude of the eye blink to the strong tone, maximally at intervals of 100 to 200 msec, but was never seen to produce any of the anticipatory impedance changes that would be characteristic of middle ear reflex activity during the interval between the two stimuli. 相似文献

Huitema and McKean (Psychological Bulletin, 110, 291–304, 1991) recently showed, in a Monte-Carlo study, that five conventional estimators of first-order autocorrelation perform poorly for small (< 50) sample sizes. They suggested a modified estimator and a test for autocorrelation. We examine an estimator not considered by Huitema and McKean: the C-statistic (Young, Annals of Mathematical Statistics, 12, 293–300, 1941). A Monte-Carlo study of the small sample properties of the C-statistic shows that it performs as well or better than the modified estimator suggested by Huitema and McKean (1991). The C-statistic is also shown to be closely related to the d-statistic of the widely used Durbin-Watson test. 相似文献

This study compared college students' understanding of the role of three language learning theories (operant, sociolinguistic, cognitive) in language theory through two instructional methods: video-based anchored instruction and traditional classroom instruction. Results indi-cated no significant difference between the performance of students in the two instructional groups on the post-test while students who received anchored instruction scored significantly higher on two transfer tests than students who received the traditional instruction. Video-based anchored instruction was found to be a valuable instructional tool which increased students' understanding of theoretical principles; through observations they experienced abstract theoretical principles as the foundation for clinicians' actions and interactions with language-impaired children. 相似文献

Death anxiety in Japan and Australia 总被引:1,自引:0,他引:1
This study compared death anxiety ratings as measured by the Templer Death Anxiety Scale (Templer, 1970) in 121 Japanese and 139 Australian subjects. Japanese subjects had significantly higher death anxiety scores than their Australian counterparts. Australian women scored significantly higher than Australian men, but no sex differences were found in the Japanese sample. A slight but statistically significant positive correlation was found between age and death anxiety scores. This study contradicted other research that indicated that Eastern cultural attitudes mitigated anxiety about death. These findings are discussed in relation to the complex relationship between culture and death anxiety as well as in relation to problems inherent in our current conception of death anxiety. 相似文献
