Lisa M. W. DaDeppo 《Learning disabilities research & practice》2009,24(3):122-131
Despite increased enrollment, outcomes such as grade point average (GPA), persistence, and graduation rates for college students with learning disabilities (LD) continue to lag behind those of their nondisabled peers. Reasons for the differences vary but may include academic and social integration, factors identified as important to the success of college students in general. This research investigated the relative influence of background characteristics, precollege achievement, and college integration variables on the academic success and intent to persist of college freshmen and sophomores with LD. While academic and social integration were not unique predictors of college GPA, both integration variables were unique predictors of intent to persist. The findings suggest that beyond high school achievement and background characteristics, college experiences as captured by academic and social integration are promising constructs to help explain the persistence of college students with LD. Implications for future research and practices for high school and college personnel are discussed. 相似文献

A growing number of studies examine the influence of individual factors on acculturation attitudes of immigrants, but few studies focus on majority members’ attitudes. In this paper, two studies are reported on the relation between attachment styles and acculturation attitudes of both immigrants (N=177) and majority members (N=243) in the Netherlands. Until now very few studies have associated cultural adjustment with attachment styles. This is remarkable, because attachment theory refers to interaction with others in new situations. Four different styles of attachment (the secure, dismissing, preoccupied and fearful attachment styles) are related to Berry's classification of acculturation attitudes. People, both immigrants and majority members, with a secure attachment style were positive towards integration, whereas people with a dismissing attachment style were not. Dismissing immigrants were more positive towards separation. Whereas both immigrants and majority members with a secure attachment style showed a similar pattern of correlations between attachment and acculturation, they seem to react quite differently, and even in opposite ways, when they have a preoccupied attachment style. Yet, the different reactions may be caused by the same psychological process: The existential ambivalence of preoccupied people may lead to diverse reactions. 相似文献
