Age and sex differences in beliefs about strategies for reducing parental anger were assessed. The central question was whether direct intervention strategies are the most effective for, and reflect more advanced understanding of, anger reduction. In Study 1, 120 children ages 4-9 years generated strategies they believed would lessen a parent's anger elicited by 3 situations of increasing complexity. Across ages children proposed direct intervention strategies for the simplest situation, and there was an age increase in suggesting direct intervention strategies for the more complex situations. In Study 2, 180 children, ages 4-12 years, and their parents rated the effectiveness of the strategies generated for the most complex situation (interparental argument). There was no longer a unilinear age increase in believing direct intervention strategies effective. Unlike with older and younger children, there was no agreement between 7-9-year-olds and their parents on the efficacy of direct intervention strategies. 相似文献

Income levels and percentage change in 1971–1975 income were regressed on personal and institutional variables for husband and wife doctorates holding full-time academic positions. Results of the composite equation indicate a $1,254 premium associated with being male after controlling for the other variables. Composite results also indicate a negative relationship between income for one spouse and the perceived opportunities for employment of the other spouse. Separate equations for the spouses indicate that this result related only to the wives' perceived opportunities of their husbands' income. By eliminating individuals with education doctorates and substituting the husbands' weights for the wives', the $1,254 differential was partially eliminated. The remaining differential between husbands' and wives' income was due to the greater involvement of the males in consulting and administration, greater involvement of the women in education, and fewer number of years of full-time experience of the wives. Comparison of income changes in both the composite and separate equations indicate that the wives received an 8–9% greater income increase than their husbands. 相似文献

Unwillingness to share depression experiences with primary care physicians contributes to the undertreatment of depression. This project examined college students’ reasons for depression nondisclosure to primary care providers (PCPs). Undergraduate participants read a vignette describing someone with depression and completed measures of disclosure barriers. Analyses indicated 26% of respondents would NOT disclose depression symptoms to PCPs. Reasons for nondisclosure included difficulty initiating the depression conversation, medication aversion, and fear of referral to a psychologist. Also, anger toward the vignette character varied with disclosure willingness, suggesting that nondisclosers feel more stigma than disclosers and are less likely to engage in psychotherapy. Because engagement in pharmacological and/or psychotherapeutic treatment requires identification of depression in healthcare settings, increased understanding of disclosure barriers could increase students’ access to depression treatment. 相似文献

This paper reports part of an investigation into how tertiary‐level distance students use and learn from textual materials during actual study sessions. Methods used provided biographical data on students and students' perceptions of their study approaches and access to the moment‐by‐moment thinking of students during study. Close‐ups of students at work provided by analysis of these data were not flattering. They revealed that students were satisficers, processed text at a rate consistent with a surface approach, avoided in‐text questions and activities wherever possible and made limited use of aspects of the text's access structure. Reasons for the poorer‐than‐expected study performances are considered as well as ways of improving text design to enhance the quality of learning. 相似文献

The aim of this study was to investigate young children's conflict emotions during peer disputes. Twenty-seven 4- to 5-year-old children participated in four 15- minute sessions in which groups of 3 children played with table toys. Videotapes of these sessions were used to identify all conflicts and conflict roles (initiator, recipient, and observer) and all conflict-related displays of facial emotions (using the AFFEX coding system). Results indicated that initiators', recipients' and observers' emotions differed in the conflict and postconflict periods, but that there were no initial preconflict differences. Overall, conflict initiators almost exclusively expressed happiness, whereas conflict recipients expressed mostly sadness and anger. In addition, children's conflict emotions were related to the frequency with which they initiated and received conflicts. Children who expressed higher percentages of negative emotions as conflict recipients both initiated and received more conflicts, and children who expressed more happiness when initiating conflicts also initiated more conflicts. These findings have implications for how young children develop methods of conflict resolution, and how they form concepts about sociomoral emotions. 相似文献

Catholic schools have become a popular choice for many low income families Latino/a families. Families enrollment in these schools are often faced with the mandate to participate. However, regardless of the mandate, some schools often experience low parental participation. The purpose of this study is to document the experiences of low income, Latino/a families around parental involvement in hopes of understanding the reasoning for participating (or not) in their child’s school. The researchers conclude that families do not participate for a number of reasons including lack of opportunities, and an unwelcoming environment. The implications for Latina/o urban education are discussed. 相似文献

In seven experiments, 2 squirrel monkeys were given choices between arrays of food that varied in the quantity offered. In Experiments 1-5, the monkeys were offered choices between quantities of the same food that varied in a 2:1 ratio. The squirrel monkeys failed to show the temporal myopia effect or a decrease in preference for the larger quantity as the absolute number of food items offered increased. Even when given choices of 8 versus 16 peanuts and 10 versus 20 peanuts, both monkeys significantly preferred the larger quantity. An examination of the monkeys' rates of consumption indicated that 20 peanuts were consumed over a 1- to 2-h period, with eating bouts separated by periods of nonconsumption. In Experiments 6A, 6B, and 7, food was either pilfered or replenished 15 min after an initial choice, so that choice of the smaller quantity led to more total food in the long run. These manipulations caused both monkeys to reduce choice of the larger quantity, relative to baseline choice. The results suggest that squirrel monkeys anticipated the future consequences of their choices. 相似文献
