In three experiments, deaf children in the age range of 6 years, 10 months to 15 years, 5 months were presented with continuous lists of items, and for each item they had to indicate whether it had appeared before on the list. Later items were related to preceding items either in surface form or in meaning or were unrelated. False-recognition errors (i.e., “yes” responses to new items) served as an index of memorial coding. In one experiment, the items presented to the subjects were printed words. The results of this experiment showed a false-recognition effect (i.e., more errors to related words than to unrelated words) for both semantically related words and orthographically similar words. In the other two experiments, the subjects viewed a series of manual signs on videotape. In these experiments, there was a false-recognition effect for signs related semantically and for signs related cherologically (i.e., similar in terms of their manual production). These results establish orthography and cherology as effective memorial codes for deaf children. The finding of a consistently strong semantic effect for young deaf children stands in contrast to findings of weak semantic effects in false-recognition studies with young hearing children. The ascendancy of semantic codes for deaf children was attributed to the absence of competition from the speech code which dominates the linguistic memory of hearing children. 相似文献

This study investigated the differences in vocational attitude maturity and self-concept among Holland's six vocational categories. Data regarding self-concept, vocational attitude maturity, and vocational preference were gathered from 846 students randomly selected from grades 8–12 in an urban school system. An analysis of variance supported the research hypotheses: (1) There were significant differences in vocational attitude maturity among students in the six vocational categories; (2) there were significant differences in self-concept among students in the six vocational categories; (3) there was a significant relationship between vocational attitude maturity and self-concept among students in specific vocational categories. 相似文献

Nurses were asked to rate patients differing in diagnosis and personality type. Two diagnosis conditions (psychogenic or physiogenic) were compared across two personality conditions: Mr. Cummings, a hypothetical patient presented to nurse/subjects via audiotape, willingly disclosed information about his illness in a nonemotional manner; while Mr. Lockwood, the second “patient”, disclosed less and was more emotional. Two control conditions were also included: One measured subjects' reactions to the personality type independent of diagnostic label; the second determined nurses' stereotypic reactions to the two diagnostic labels alone. Subjects reacted more favorably to Mr. Cummings than to Mr. Lockwood regardless of Cummings' diagnosis. Nurses' impressions of Mr. Lockwood, on the other hand, varied as a function of his diagnosis. 相似文献

A reinforcement system utilizing instructions, modelling, feedback, and group reinforcement was employed in an attempt to reduce disruptive noise on three university residence halls. A fourth hall received the same treatment program without the reinforcement component. Noise scores were determined by recording the number of discrete noise occurrences over a criterion decibel level. On all four residential floors, noise scores during treatment conditions were lower than initial and final baseline levels. Additionally, periods of noise reduction corresponded to the changing criterion multiple-baseline and reversal designs utilized. Pre- and posttreatment questionnaire responses from the three reinforcement floors paralleled changes in objective noise data. At posttreatment, residents reported less noise disturbance of study and sleep and more control over the noise situation and floor problems in general. These results indicated that a comprehensive behavior-modification treatment package was effective in reducing disruptive noise in university residence halls. Difficulties in data collection and anomalies in the data are discussed. Future directions for field-based behavior-modification research are outlined. 相似文献
