In this study, we explore the effects of non-normality and heteroscedasticity when testing the hypothesis that the regression lines associated with multiple independent groups have the same slopes. The conventional approach involving the F-test and the t-test (F/t approach) is examined. In addition, we introduce two robust methods which allow simultaneous testing of regression slopes. Our results suggest that the F/t approach is extremely sensitive to violations of assumptions and tends to yield misleading conclusions. The new robust alternatives are recommended for general use. 相似文献

The present research used a latent variable trait–state model to evaluate the longitudinal consistency of self-esteem during the transition from adolescence to adulthood. Analyses were based on ten administrations of the Rosenberg self-esteem scale (Rosenberg, 1965) spanning the ages of approximately 13–32 for a sample of 451 participants. Results indicated that a completely stable trait factor and an autoregressive trait factor accounted for the majority of the variance in latent self-esteem assessments, whereas state factors accounted for about 16% of the variance in repeated assessments of latent self-esteem. The stability of individual differences in self-esteem increased with age consistent with the cumulative continuity principle of personality development. 相似文献

Guala argues that there is a mismatch between most laboratory experiments on costly punishment and behavior in the field. In the lab, experimental designs typically suppress retaliation. The same is true for most theoretical models of the co-evolution of costly punishment and cooperation, which a priori exclude the possibility of defectors punishing cooperators. 相似文献

Past studies have correlated observer ratings with questionnaire self- and partner-reports of behaviors in close relationships. However, few studies have actually proposed and tested longitudinal models that link observer ratings to past behaviors and to questionnaire self- and partner-reports of behaviors during an observational task. Using data from a panel of 324 young couples, we demonstrate that (a) observer ratings of hostility and support are significantly related to couple reports of the same behavior in the relationship two years earlier, and (b) respondent and partner questionnaire reports of hostility and support during the observational task converge with observer ratings of the same behavior even after controlling for earlier self- and partner-reports. These findings demonstrate that observer reports based on brief discussion tasks reflect the tenor of the relationship over a relatively long period of time. They also demonstrate that couple reports of interactions reflect observable behaviors beyond that attributed to earlier self- and partner-reports. Consistent with previous research, effect sizes are larger for hostility than support but there are few differences between men and women. 相似文献

The construct validity of the Wallach-Kogan (W-K) creativity test was investigated through an hierarchical factor analysis of intercorrelations among intelligence, creativity, control, and criterion variables for 73 Ss enrolled in grades 3 and 4 of an inner-city parochial school. The results provided considerable support for W-K's theoretical formulations. Creativity and intelligence assessors defined separate domains and remained totally resilient to merger into a superordinate factor. The creativity domain, which was defined by W-K subtests and criterion ratings, included the following factors: general, visual, and verbal creativity plus a weak methods factor for crayon drawings. The intelligence domain, which was defined by WISC subtests, included a relatively strong g factor and the following four primary factors: verbal precision, freedom from distractibility, perceptual organization, and quasi-specific. 相似文献

Support for religio‐political aggression among teenaged boys in Gaza: Part I: psychological findings

Politically aggressive militant groups usually rely on support from a larger community, although evidence suggests that only some members of that larger community support that aggression. A major subtype of political aggression is that associated with religious differences—or Religio‐Political Aggression (RPA). Little previous research has explored demographic or psychological factors that might distinguish supporters from non‐supporters of RPA. In an exploratory study, we investigated whether factors previously associated with aggression might correlate with support for RPA in the case of the Israeli/Palestinian conflict. During the second intifada, fifty‐two 14‐year‐old Palestinian boys in Gaza completed self‐report measures of life events, emotional status, and political attitudes. Teenaged boys who reported family members having been wounded or killed by the Israeli Defense Forces (IDF) expressed greater support for RPA (t(50)=?2.30, P=.026). In addition, boys who felt their group was treated unjustly reported greater support for RPA compared with those who did not (t(50)=?2.273, P=.027). Implications of these preliminary data are discussed. Aggr. Behav. 36:219–231, 2010. © 2010 Wiley‐Liss, Inc. 相似文献

This commentary summarizes findings from four papers that set out to replicate, albeit not with identical measures or sampling criteria, research on several questions in the multigenerational study of antisocial behavior by children and child-rearing strategies by parents. The weight of the evidence from our studies indicates some degree of intergenerational continuity in behavior. We observed that adjacent generations G1 and G2 are similar with respect to their styles of parenting and that adjacent generations G2 and G3 are similar with respect to antisocial behavior. In addition, the G2 parent's parenting style plays an important role in mediating or transferring the risk of antisocial behavior across the generations. Implications and directions for future research are discussed. 相似文献

Using data from a sample of 673 Mexican Origin families, the current investigation examined the degree to which family supportiveness acted as a protective buffer between neighborhood disorder and antisocial behavior during late childhood (i.e. intent to use controlled substances, externalizing, and association with deviant peers). Children's perceptions of neighborhood disorder fully mediated associations between census and observer measures of neighborhood disorder and their antisocial behavior. Family support buffered children from the higher rates of antisocial behavior generally associated with living in disorderly neighborhoods. An additional goal of the current study was to replicate these findings in a second sample of 897 African American families, and that replication was successful. These findings suggest that family support may play a protective role for children living in dangerous or disadvantaged neighborhoods. They also suggest that neighborhood interventions should consider several points of entry including structural changes, resident perceptions of their neighborhood and family support. 相似文献
