The feeling of knowing for different types of retrieval failure 总被引:3,自引:0,他引:3
992.
In previous work, it has been demonstrated that phonetic similarity among the items in a spoken list interferes with recall much more in school-aged children than in preschool children. The basis of this developmental change, however, is unclear. In the present study we examined the possibility that a developmental increase in the use of covert verbal rehearsal accounts for the change in the effects of phonetic similarity. Adults who recalled lists of spoken words during articulatory suppression tasks that blocked covert rehearsal were found to display patterns of recall that resembled those ordinarily found in 5-year-old children. The specific aspects of rehearsal responsible for these effects also were investigated. 相似文献

A habituation test paradigm was used to examine the responses of free-living territorial adult male song sparrows (Melospiza melodia) to a range of synthetic songs. The three-phrased test songs differed from one another in having either conspecific or heterospecific (swamp sparrow, M. georgiana) syllables, or silence, in the second phrase. Subjects were exposed to repeated presentations of one song type until their approach distance to a loudspeaker increased. In one experiment, birds were habituated with a song consisting of three phrases of song sparrow syllables and then tested for generalization to either novel song sparrow syllables in the second phrase, swamp sparrow syllables, or silence. Birds discriminated between song sparrow syllables on two response measures, and between song sparrow and swamp sparrow syllables on one measure. In a second experiment, after habituation to a song with swamp sparrow syllables in the second phrase, birds did not generalize to novel song sparrow syllables, but they did generalize to novel swamp sparrow syllables. Thus song sparrows make finer distinctions among conspecific syllable variants than with alien syllables. The results further suggest that subtle species-specific differences in note structure within syllables are discriminated by song sparrows and potentially provide an adequate basis for individual recognition by song. 相似文献

Stimulus equivalence seems to have relevance to the study of semantics and of language more generally. If so, there may be a relation between language use and the demonstration of stimulus equivalence. This was examined in three groups of children ranging in chronological age and matched on a conventional measure of mental age: normally developing preschoolers, retarded children who used speech or signs spontaneously and appropriately, and retarded children who did not. All children were taught a series of four related discriminations and were then tested to determine if classes of equivalent stimuli had formed. All of the language-able children (retarded and normal) formed equivalence classes, whereas none of the language-disabled children did so. Although the exact nature of the relation between stimulus equivalence and language remains to be clarified, these results support the view that stimulus equivalence is a phenomenon with relevance to language. 相似文献

Effects of alcohol intoxication on metamemory and on retrieval from long-term memory 总被引:2,自引:0,他引:2
T O Nelson M McSpadden K Fromme G A Marlatt 《Journal of experimental psychology. General》1986,115(3):247-254
In a balanced-placebo design, people expected either an alcohol drink or placebo drink and consumed either alcohol (1 ml/kg) or placebo. Shortly thereafter, each person attempted to recall the answers to general-information questions (e.g., "What is the capital of Chile?"), made confidence judgments about the accuracy of recall, made feeling-of-knowing judgments on all nonrecalled items, and received a recognition test. Unanticipated outcomes included: Alcohol intoxication significantly hindered recall from long-term memory, contrary to previous conclusions that alcohol does not affect retrieval; people's expectancy of alcohol had no significant effect on memory or metamemory performance, contrary to its established effects on other kinds of performance; and alcohol intoxication produced no significant overconfidence in judgments about recall or in feeling-of-knowing judgments, contrary to the overconfidence produced in other kinds of judgments such as an intoxicated person's assessment of his driving ability. This last outcome implies that alcohol intoxication does not produce a general lowering of the threshold for confidence but rather has effects that are situation specific. 相似文献

Ebbinghaus's contribution to the measurement of retention: savings during relearning 总被引:2,自引:0,他引:2
The focus here is on Ebbinghaus's sole measure of retention: savings during relearning. The article is divided into four sections: (a) the historical perspective surrounding Ebbinghaus's use of savings and relearning (including a fundamental difference between Ebbinghaus's conception of memory and that of his contemporaries such as William James), (b) potential problems with savings as a measure of retention, (c) recent findings based on savings and relearning, and (d) applications of savings and relearning. 相似文献

The main purpose of this study was to examine the degree to which apparently sex-typed subjects manipulated behaviors on the Sex Role Motor Behavior Checklist in response to instructions to convey specific sex-role impressions. Extremely masculine and feminine males and females (10–12 per group) were assessed for their ability to change sex-related motor behavior upon request. Subjects were able to produce significant increases in masculine and feminine motor behavior, particularly in the areas of walking and sitting. Many individual behaviors, however, showed small or inconsistent changes. Apparently, many of the motor differences naturally displayed by males and females are either not consciously part of sex-typed adults' concept of given sex roles or are relatively inflexible in this population. Secondary purposes of the study were to identify specific sex-related motor behavior (a) to alter when changes in sex role seem desirable and (b) to utilize as dependent measures in measuring changes in sex role. Walking and sitting were shown to be especially important areas.The authors would like to thank David Millsaps, Reid Smith, Donna Gosnell, Ruth Rankin, and Stephanie Stohr for their assistance. 相似文献
