A communication approach to the acculturation process: A study of Korean immigrants in Chicago     

Young Yun Kim 《Int J Intercult Relat》1978,2(2):197-224

This paper explores a theoretical and methodological basis for studying foreign immigrants' acculturation processes from a communication perspective. Communication patterns of immigrants are conceptualized on three levels — behavioral, attitudinal, and perceptual. The behavioral level of communication includes the immigrant's participation in communication channels of the host society as well as the ethnic community. The perceptual level refers to the immigrant's cognitive structure in perceiving the host society. The attitudinal level is examined by the immigrant's affective-evaluative orientation toward the host society. The three levels of communication patterns were empirically investigated in a survey of 400 randomly selected Koreans in the Chicago area. The communication variables were assessed through composite scores using questionnaire items that were tested for reliability. The results show an overall linear trend in the immigrant's interethnic communication with Americans, positive attitude toward Americans, cognitive complexity in perceiving the American society, and satisfaction level. A simultaneous increase is observed in the immigrant's interpersonal communication with Americans and with other Koreans. The immigrant's use of ethnic media rapidly decreases over the years while that of American media steadily increases. Findings are discussed in comparison to previous studies of foreign immigrants and students and to sociological theories of acculturation of minority groups.  相似文献   

Effects of delayed retention on multiple-choice test performance     

Gary Phye  Joseph Gugliemella  Janet Sola 《Contemporary educational psychology》1976,1(1):26-36

In two experiments, immediate feedback defined as feedback following the completion of a 40-item multiple-choice test and delayed feedback (received 48 hr later) were examined in a simulated classroom situation with college students. As defined, delayed feedback was not superior to immediate feedback, as would be predicted by the delayed retention effect. Also, feedback in the form of correct answer only was superior to correct answer plus distractors lending partial support to the frequency theory of recognition memory. In addition to not finding the delayed retention effect, an analysis of errors in experiment two did not support the interference—perseveration hypothesis as an explanation for the type of error committed following immediate feedback.  相似文献   

Sensitivity to orthographic structure in educable mentally retarded children     

Richard L. Allington 《Contemporary educational psychology》1981,6(2):135-139

Thirty educable mentally retarded (EMR) children were presented an item selection task to assess their sensitivity to orthographic structure in printed English words. Analyses of performance indicated that EMR children do acquire implicit knowledge of orthographic rules and that this ability is related to the development of reading skills.  相似文献
