The incidence of homonymy in children's early sign language production was examined in nine young children of deaf parents. Analysis of parental reports of how their children formed their signs revealed that all of the children produced homonymous forms (i.e., a single manual form used to represent two or more different adult target signs). Altogether, the children were reported as producing 26 sets of homonymous forms to represent 59 adult target signs. This incidence of homonymy in the children's early signing did not differ significantly from the incidence of homonymy previously reported in a study of normally developing children acquiring spoken language. This finding is interpreted as indicating an important similarity in language acquisition processes across language modalities. Analysis of the sign formational characteristics of the children's homonymous forms revealed that the children's signs and the adult target signs typically shared a common location aspect. The movement and handshape aspects of the adult target signs were less frequently retained in the children's homonymous forms. 相似文献

On each trial, Ss attempted to retain a series of five visually presented letters while concurrently “shadowing” (repeating aloud) a rapid series of aurally presented letters. If serial-position accuracy is ignored, they were able to store more than only the last letter of a typical series, even though all five letters appeared on the same screen, and that performance was superior to the retention of five auditorily presented letters. Together, these findings suggest that a form of visual storage might have been employed for the retention of visual stimuli and, specifically, one that was relatively immune to erasure as compared to “iconic” storage. In further support of that hypothesis, retention of such visual series as measured by free-recall accuracy was not inferior to that of five letters, each of which was presented on a separate screen. 相似文献

When knowledge of the response sequence permits one to specify the sequence of theoretical states that occurred, we propose to say that the theory has observable states. Our earlier usage of identifiable conflicts with established usage in econometrics. We also present a revised definition of implication between theories that avoids a technical flaw in the earlier definition, and we correct a mistake in an example in our earlier paper. 相似文献

Two-hundred-twelve sociology students completed a version of Rokeach's Value Survey in which the presentation order of the values was randomized. Each respondent received a unique randomization pattern. Spearman's correlations were computed between the presentation order and the order of ranking done by the respondent. The magnitude of the correlations obtained was such that the amount of bias created by presentation order was sufficiently small as to suggest that order effects are not a problem in the instrument. 相似文献
