Six groups of 20 subjects each were run individually in a binary prediction situation with each alternative occurring equally often. Two age groups were employed; subjects were either in second or sixth grades. For one-third of the subjects at each age level, the events occurred in runs of either two or six; another third observed events which occurred in runs of either five or six; the other subjects received a random sequence of events. All subjects then received an additional 50 trials in which every prediction was correct. The results indicated some sensitivity to run length characteristics. Fewer errors of all types were made in the prediction of 5–6 sequences. The verbal reports and all-correct trial protocols revealed that at least the sixth graders employed some simple run length structure rules, although many instances of runs other than those presented in training occurred, showing much processing error. The results were discussed in terms of a general limited-capacity model of information-processing.  相似文献

Four parents enrolled in a Responsive Teaching class carried out experiments using procedures they had devised for alleviating their children's problem behaviors. The techniques used involved different types of reinforcement, extinction, and punishment. One parent increased the frequency of the wearing of an orthodontic device during five daily time checks by making an immediate monetary payoff contingent on wearing the device. A second parent increased the number of points earned for doing daily household tasks by providing back-ups for which the points could be exchanged. The parents of a 4-yr-old boy decreased the frequency of whines, cries, and complaints by removing social attention when such behavior occurred. A mother decreased the duration of time it took for her 5-yr-old daughter to get dressed by making permission to watch television contingent on dressing within 30 min of the time she got up in the morning. Brief reversals of contingencies were used to show causal relationships between the procedures used and the changes in behavior. Checks on the reliability of measurement were made by persons present in the home.  相似文献

A cross‐sectional study of educated men and women showed that cautiousness, as measured by perceived problem‐solving ability, does not increase with age. Sex differences were nonsignificant. The results are discussed in terms of R. Schultz and J. Heckhausen's (1996) Life Span Model of Successful Aging.  相似文献

Children's recall of the details of pediatric examinations was examined over the course of a 6-month interval. Although the 83 4- to 7-year-old participants reported a substantial amount of information at each assessment, performance declined over time, dropping sharply over the course of 3 months but then remaining constant out to the final interview at 6 months. As expected, older children provided more total information than younger children did and reported a greater proportion of the event components in response to general rather than specific questions. However, comparable patterns of remembering and forgetting over time were observed at each age level. In addition, no effects of repeated questioning--in the form of an interview at 3 months for half of the children--were observed on performance at the 6-month assessment. Moreover, children's prior knowledge about routine doctor visits was assessed before the checkup for half of the participants at each age and was associated with initial but not delayed recall. Although knowledge increased with age as expected, it nonetheless affected recall over and above the influence of age.  相似文献

Two studies are presented which test whether justice can motivate support for government policies and authorities even when such support is not in people's obvious personal or group interest. In the first study, White San Francisco Bay area residents' attitudes toward Congressionally-authored affirmative action policies and anti-discrimination laws were investigated. In the second study, African-American San Francisco Bay area residents' feelings of obligation to obey the law were investigated. The results from both studies show a significant relationship between evaluations of social justice and respondents' political attitudes. More importantly, a significant relationship between relational evaluations of Congress and political attitudes is found in both studies. This relationship suggests how justice can motivate policy and government support even if such support does not yield direct personal or group benefits. Finally, the results from both studies indicate when instrumental and relational concerns will be related to political attitudes. If people identified with their particular advantaged or disadvantaged group, instrumental concerns were more strongly related to their political attitudes, but if people identified with a superordinate category that included both potential outgroup members and relevant superordinate authorities, relational concerns were more strongly related to their political attitudes.  相似文献

The young adult years are particularly important for accruing the education and work experience needed for long-term economic stability. We examine the effects of symptoms of ODD at baseline (i.e., T1 ages 12 to 18 years; N = 662; 48 % male) and of increases in these symptoms on academic and occupational functioning in young adulthood (i.e., T6 ages 22 to 29 years; N = 478; 45 % male) using multiple measures; including achievement levels (i.e., educational attainment, occupational prestige, and income) and financial and work stress (i.e., debt, financial strain, and perceived workplace stress). Our findings show that both adolescent levels of and increases in symptoms of ODD influence academic and occupational functioning in young adulthood. We discuss the implications of ODD symptoms for accruing economic capital in young adulthood, as well as approaches to detecting and intervening that are needed to halt the potentially cascading effects of ODD symptoms.  相似文献
