Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection. 相似文献

To adequately monitor progress in writing, a test must show stability and demonstrate a performance profile over time that parallels those of accepted criterion measures. This study investigated the technical adequacy of seven objective indexes of writing quality in monitoring the progress of 36 middle school (Grades 6-8) students with mild disabilities over a 6-month period. The stability of each index was assessed. Holistic ratings of the same writing samples and the Test of Written Language served as validation criteria. Three indexes were moderately correlated with holistic ratings, but were not sufficiently stable over time. Direct, objective writing assessment must be used with caution for progress monitoring, given our present lack of precision in measuring the complex task of writing. 相似文献

In this article, we discuss the intuitive knowledge mothers have of their unborn baby. We propose a shift in focus from caregivers' merely providing information to first listening to pregnant mothers as they share their intuitive knowledge of their baby. This approach enables mothers and fathers or partners to know they are already parents to their unborn baby and empowers them to get in touch with their baby's presence and who he or she is during pregnancy. This intuitive knowledge may be a protective behavior that will enable mothers to keep babies safe during pregnancy. 相似文献

Forming, Losing, Renewing, and Replacing Friendships: Applying Temporal Parameters to the Assessment of Children's Friendship Experiences 总被引:2,自引:0,他引:2
Friendship formation and dissolution were tracked over time in a summer camp to examine whether such events are valid indicators of individual differences in children's friendship adjustment. Subjects were 216 children ages 8–15 years. Sociometric nominations were used to determine the identities of reciprocal friends. Loneliness at camp was also tracked over time. In addition, data on group acceptance, behavioral reputations, social competence, and behavioral problems were gathered from peers and counselors. Analyses suggested that friendship formation and duration were coherent, independent dimensions of individual differences and distinct from the overall extensivity of involvement in friendships. Regression analyses indicated that the temporal parameters of participation in friendship enhanced the prediction of changes in loneliness at camp. Age and sex differences in temporal parameters were explored, and 4 discrete trajectories for friendship involvement were identified. Children with different trajectories differed in their behavioral profiles from one another and from children who were chronically friendless. 相似文献

The goals of this research were to explore the current literature regarding associations between psychological stress and adverse fetal outcome, associations between aerobic exercise and psychological stress reduction, and associations between aerobic exercise and fetal outcome. The published studies that were located provide evidence of the following: 1) Stress reactivity increases physiologically during pregnancy, 2) pregnant women may experience additional stressors that are usually not experienced in a nonpregnant state, 3) psychological stress in pregnancy is associated with adverse fetal outcome, 4) exercise can be a method of stress reduction, 5) exercise in pregnancy is not associated with adverse fetal outcome, and 6) exercise in pregnancy may provide benefit to the fetus. Data were analyzed from an original study and associations were reported between psychological stress-management activities and participation in aquatic aerobic exercise classes. No reports were available investigating an exercise-induced reduction in psychological stress with fetal outcome. 相似文献

Body position is known to alter power production and affect cycling performance. The aim of this study was to compare mechanical power output in two riding positions, and to calculate the effects on critical power (CP) and W′ estimates. Seven trained cyclists completed three peak power output efforts and three fixed-duration trial (3-, 5- and 12-min) riding with their hands on the brake lever hoods (BLH), or in a time trial position (TTP). A repeated-measures analysis of variance showed that mean power output during the 5-min trial was significantly different between BLH and TTP positions, resulting in a significantly lower estimate of CP, but not W′, for the TTP trial. In addition, TTP decreased the performance during each trial and increased the percentage difference between BLH and TTP with greater trial duration. There were no differences in pedal cadence or heart rate during the 3-min trial; however, TTP results for the 12-min trial showed a significant fall in pedal cadence and a significant rise in heart rate. The findings suggest that cycling position affects power output and influences consequent CP values. Therefore, cyclists and coaches should consider the cycling position used when calculating CP. 相似文献
