This study compares affective and motivational components of academic life for traditional and nontraditional university undergraduates. Traditional students are defined as those aged 21 and younger, who are most likely to have followed an unbroken linear path through the education system, whereas nontraditional students are defined as those aged 28 and older, for whom the undergraduate experience is not necessarily age normative. A total of 300 undergraduates ranging in age from 18 to 60 years were assessed on measures of intrinsic and extrinsic motivation to learn, interest, and positive affect. Nontraditional students reported higher levels of intrinsic motivation for learning than did traditional students. Intrinsic motivation correlated with positive affect more strongly for nontraditional than for traditional students. For all students, interest and age emerged as significant predictors of intrinsic motivation to learn, and both interest and intrinsic motivation significantly predicted positive affect.
The hypothesis that individual differences in adult intellectual development reflect variation in life context and personality was examined in 132 World War II (WWII) veterans. Intelligence data from the Canadian Army M Test were available for 3 occasions, WWII, 1984-1986 (Int85), and 1989-1991 (Int90). Performance declined over the 45 years on 5 subtests but improved on the 6th, Vocabulary. Correlations between WWII and Int90 scores showed considerable stability of individual differences in intelligence over 45 years. Younger age predicted less decline over 45 years on all subtests; a more engaged lifestyle predicted less decline on most subtests, and better health and greater introversion predicted less decline on some subtests. Predictors of change since Int85 were similar to those for the whole period. Implications for theories of adult intellectual development are discussed.
This study investigated the hypothesis that older adults would show age-related reductions in the tendency to worry in both their retrospective accounts and through cross-sectional age comparisons with a sample of younger adults. We also sought to determine whether age differences would be evident in psychological processes associated with a tendency to worry in general adult samples (intolerance of uncertainty and beliefs in the functional value of worry). Support was found for the hypothesized age-related reduction in worry in both retrospective reports among the older adults and cross-sectional age comparisons. Older adults were also found to report less intolerance of uncertainty and
The referential communication task was used to see if high off-target verbosity (OTV), defined as excessive speech that is lacking in focus, negatively affects communication of nonautobiographical information. The task required 1 individual (the director) to communicate descriptions of abstract figures to another (the matcher). Out of 455 adults aged 63 to 93 who were screened for OTV, 27 directors were drawn from each of the top and bottom 15% of the range of OTV scores and 26 directors and all 80 matchers from the middle 50%. High OTV directors were less efficient communicators about the figures and showed poorer inhibitory control but did not intrude personal information in their speech. The implications of the findings for the inhibitory deficit and pragmatic change explanations of OTV are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
