Though self-esteem is known to positively impact individuals’ romantic relationship outcomes and those of their partners, the interactive nature of both partners’ self-esteem levels has not been systematically investigated. Using actor-partner interdependence model analyses we estimated actor, partner, and four types of dyadic effects of self-esteem on relationship quality in a sample of over 500 heterosexual dating couples. Lower self-esteem individuals and their partners reported lower satisfaction and commitment to their relationships than did higher self-esteem individuals and their partners. An additive effect whereby both partners’ self-esteem levels combine to predict relationship quality best described the dyadic effects. Results highlight the importance of considering the interactive nature of individual characteristics in dyadic research. 相似文献

Haptic guidance by a robot is a recent technology to support motor learning. Its mechanisms and effects are not yet well understood. One of the hypotheses is that learning of temporal characteristics is particularly susceptible to the beneficial effects of robotic guidance. In this study we investigate the influence of robotic guidance on the production of spatio-temporal patterns. Participants practiced to draw circles with the velocity profile of ellipses. Performance during the practice phase, when participants were assisted by a robotic device, as well as during the test phase, when assistance was switched off, was compared to a control group. During practice participants with robotic assistance performed better on all three dependent measures, shape, timing of the velocity modulation, and modulation amplitude. However, these differences between groups largely disappeared in the test phase. Only the difference in the amplitude of the velocity modulation remained, which was more accurate in the robot-guidance group than in the control group. This remaining difference likely results from a secondary effect of robotic guidance, namely the experience of smaller visual errors and weaker velocity modulations during practice. 相似文献

When children hear an object referred to with a label that is moderately discrepant from its appearance, they frequently make inferences about that object consistent with the label rather than its appearance. We asked whether 3-year-olds actually believe these unexpected labels (i.e., conversion) or whether their inferences simply reflect a desire to comply with the considerable experimental demands of the induction task (i.e., compliance). Specifically, we asked how likely children would be to pass an unexpected label on to another person who had not been present during the labeling event. Results showed that children who used an unexpected label as the basis for inference passed that label on to another person about as often as they could remember it. This suggests that children’s label-based inferences do reflect conversion rather than mere compliance. 相似文献

The consideration of diverse family factors on parents’ acceptance of behavioral parent training (BPT) components aids in the development and delivery of culturally sensitive parenting programs. Perceptions of acceptability are particularly important to investigate among low-income and racial-minority families, as they are less likely to engage in nonadapted BPT programs. Therefore, the current study examines the synergistic effects of race and income on mothers’ acceptance of five common child management methods relevant to BPT. The relationship between mothers’ acceptability ratings and self-reported parenting practices was also explored. Participants were 106 White and Black mothers from different income levels who completed measures related to the acceptability of response cost, positive reinforcement, time-out, spanking, and medication. The results indicated that mothers from varying backgrounds differed in their acceptance of child management methods, particularly with regard to corporal punishment. Additionally, a relationship was found between parents’ acceptability ratings and their self-reported parenting behavior. The findings support the consideration of parents’ perceptions of child discipline methods when recommending and delivering BPT programs to diverse parents. 相似文献

Effect size measures for mediation models: quantitative strategies for communicating indirect effects 总被引:3,自引:0,他引:3
The statistical analysis of mediation effects has become an indispensable tool for helping scientists investigate processes thought to be causal. Yet, in spite of many recent advances in the estimation and testing of mediation effects, little attention has been given to methods for communicating effect size and the practical importance of those effect sizes. Our goals in this article are to (a) outline some general desiderata for effect size measures, (b) describe current methods of expressing effect size and practical importance for mediation, (c) use the desiderata to evaluate these methods, and (d) develop new methods to communicate effect size in the context of mediation analysis. The first new effect size index we describe is a residual-based index that quantifies the amount of variance explained in both the mediator and the outcome. The second new effect size index quantifies the indirect effect as the proportion of the maximum possible indirect effect that could have been obtained, given the scales of the variables involved. We supplement our discussion by offering easy-to-use R tools for the numerical and visual communication of effect size for mediation effects. 相似文献

Because behavior analysis is a data-driven process, a critical skill for behavior analysts is accurate visual inspection and interpretation of single-case data. Study 1 was a basic study in which we increased the accuracy of visual inspection methods for A-B designs through two refinements of the split-middle (SM) method called the dual-criteria (DC) and conservative dual-criteria (CDC) methods. The accuracy of these visual inspection methods was compared with one another and with two statistical methods (Allison & Gorman, 1993; Gottman, 1981) using a computer-simulated Monte Carlo study. Results indicated that the DC and CDC methods controlled Type I error rates much better than the SM method and had considerably higher power (to detect real treatment effects) than the two statistical methods. In Study 2, brief verbal and written instructions with modeling were used to train 5 staff members to use the DC method, and in Study 3, these training methods were incorporated into a slide presentation and were used to rapidly (i.e., 15 min) train a large group of individuals (N = 87). Interpretation accuracy increased from a baseline mean of 55% to a treatment mean of 94% in Study 2 and from a baseline mean of 71% to a treatment mean of 95% in Study 3. Thus, Study 1 answered basic questions about the accuracy of several methods of interpreting A-B designs; Study 2 showed how that information could be used to increase the accuracy of human visual inspectors; and Study 3 showed how the training procedures from Study 2 could be modified into a format that would facilitate rapid training of large groups of individuals to interpret single-case designs. 相似文献

This study examined family stressors among 3-year-old children who were classified as hyperactive (HYP), hyperactive and oppositional defiant (HYP/OD), and non-problem based on mothers' reports of behavior. Children with HYP/OD were found to experience higher levels of family stressors than non-problem children on almost every family stressor variable. Compared to children with HYP, families of children with HYP/OD also tended to report more Axis II maternal psychopathology, Axis I paternal psychopathology, and high intensity couple conflict tactics. However, the HYP and HYP/OD group did not significantly differ on maternal Axis I psychopathology, paternal Axis II psychopathology, parental marital status, negative life events, frequency of couple conflict, or use of lower intensity couple conflict tactics. Parents of children with HYP and HYP/OD reported more negative life events, more maternal adult ADHD symptoms, and more maternal avoidance and verbal aggression during marital conflict than parents of non-problem children. Implications for treatment and etiology are discussed. 相似文献

To explore the attractiveness of VLBW infants with postnatal headmolding, 29 mothers of VLBW infants and 29 mothers of full-terms rated complimentary photographs of VLBW newborns with postnatal headmolding, VLBW newborns without postnatal headmolding, and full-term newborns. In a second study, facial conformation and infant attractiveness were assessed to determine the degree to which babyish head-shapes and infant attractiveness differed between VLBW and full-term infants. Finally, infant history, measures of facial conformation, and infant attractiveness ratings were regressed on maternal responsiveness scores. Overall, mothers rated photographs of VLBW newborns with postnatal headmolding as less cute; however, mothers of VLBW infants rated photographs of VLBW newborns with postnatal headmolding as more cute than did mothers of full-term infants. During the second half of the first year of life, VLBW infants had narrower mouths, their eyes were closer to the sides of the face, and there was a tendency for VLBW infants to have narrower heads; however, overall attractiveness ratings of VLBW and full-term infants did not differ. More babyish head shape (wider head shape, more babyish facial features) significantly predicted maternal responsiveness to infant cues in a freeplay session. Findings demonstrate that VLBW newborns with postnatal headmolding are more vulnerable to negative evaluations of perceived attractiveness, differences in head shape are evident in the second half of the first year of life, and babyish headshape may be one factor that affects the degree to which infants are able to elicit sensitive maternal responses. 相似文献

Generic statements express generalizations about categories and present a unique semantic profile that is distinct from quantified statements. This paper reports two studies examining the development of children's intuitions about the semantics of generics and how they differ from statements quantified by all, most, and some. Results reveal that, like adults, preschoolers (a) recognize that generics have flexible truth conditions and are capable of representing a wide range of prevalence levels; and (b) interpret novel generics as having near‐universal prevalence implications. Results further show that by age 4, children are beginning to differentiate the meaning of generics and quantified statements; however, even 7‐ to 11‐year‐olds are not adultlike in their intuitions about the meaning of most‐quantified statements. Overall, these studies suggest that by preschool, children interpret generics in much the same way that adults do; however, mastery of the semantics of quantified statements follows a more protracted course. 相似文献

Peer review of teaching (PRoT) is recommended to both develop and assure the quality of teaching practices in Higher Education. An institutional implementation of a peer review process can be viewed as a genuine desire to improve teaching quality or as an instrument of accountability and performativity. There are many approaches to the peer review of teaching operating. This article documents the impact, advantages and disadvantages of direct participation in three peer review of teaching processes. 相似文献
