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

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

A national survey of multicultural and ethnic attitudes in Canada was conducted in 1974 (n = 1849). Data were analysed for the 1244 respondents whose ethnicity could be determined as Angloceltic, French, German, Italian or Ukrainian Canadian, A five group by five group intergroup attitude matrix was created, with each group acting both as attitude object and as holder of attitudes. Analysis indicated the existence of reciprocity or balance in the matrix: groups tended to reflect the attitude held toward them back onto the group holding the attitude. However this structural balance was moderated by the existence of shared attitudes about the position of a group in the national ethnic hierarchy. Further analysis indicated the existence of ethnocentrism in the matrix: attitudes toward ingroup and positive reference groups were more positive than toward out-groups. Perceived intergroup similarity and familiarity were positively correlated with each other and with intergroup acceptance. Results were discussed in relation to attitude balance theory and ethnocentrism theory, and in their implication for intergroup research in multicultural societies.  相似文献

The thought models and theories of many individuals and disciplines have contributed to the study of human communication. In recent years scholars have become increasingly aware of the fact that methodologies superimposed upon the actual event of human communication have significantly shaped our perceptions of these events. Going beyond methodological approaches or quarrels, a phenomenological basis requires direct encounter with the event and an attempt to let methodology evolve out of that direct encounter, rather than attempting a so-called objective approach. Self, experience, values, and human relationships are of primary concern to the phenomenologist who sees meaning and interpretation as a unitary concept. Phenomenology thus concerns itself with understanding, and the bases for such understanding, rather than with the mere application of methodology. At the same time, phenomenology by its very approach, concerns itself not merely with the discovery of some abstract truth, but must be deeply concerned also with the improvement of the human condition founded in conscious experience. Behavior and meaning thus become conjoined. The ultimate aim of phenomenological studies becomes a concern with the ontological as well as the epistemological bases of human understanding.  相似文献

Major channels of communication are examined for two major functions: providing news of the ethnic community, and linking ethnics to the “mother country.” The four major channels are: interpersonal channels (friends and neighbors), radio, local metropolitan daily newspapers, and ethnic-language newspapers. Size of ethnic group is linked to channel preference, and greater ethnicity is related to a preference for ethnic media for both functions. Lower SES ethnics lend to rely more on interpersonal communication and ethnic media, while higher SES ethnics turn more to metro media and magazines. Channel preference as indicated by respondents is also linked to actual usage patterns.  相似文献

Two experimental procedures for positively modifying the attitudes of regular classroom children towards the handicapped were conducted. In both studies, curriculum and/or experiences with the handicapped were introduced to randomly selected groups of regular class elementary children. The curriculum consisted of literature, filmstrips, and lectures about handicapped children, while the experiences consisted of controlled integrational activities. The results indicated that the procedures were partially successful in modifying the attitudes of regular class children towards the handicapped. It was concluded that techniques must be developed systematically for achieving more positive attitudes in regular class children if “mainstreaming” is to become an effective educational concept.  相似文献

The shift toward more open and interconnected innovation activities has been a major topic in recent academic and practitioner discussions. Firms must connect their in-house R&D activities with external partners, such as leading customers or universities, to increase the effectiveness of their innovation activities. Hence, management needs to define where to search for valuable knowledge in its environment. In this paper we argue that knowledge search has to reflect the heterogeneity of various knowledge sources with regard to the knowledge they can provide and how these sources can be activated. We hypothesize that search strategies driven by science, suppliers and the product market will contribute differently to innovation success with new-to-market versus imitated products. Moreover, we explore the effect of these types of knowledge search within different sectoral patterns of innovation. Our empirical analysis rests on a sample of almost 5000 firms from five Western European countries. The results support our hypotheses and highlight the potentials and shortcomings of different types of knowledge search.  相似文献
