This time‐lag study examined if there has been any changes in body esteem over a 10‐year period for 10‐year old children in Gothenburg, Sweden. Two cohorts of children, one in year 2000 and one in 2010, answered the same questionnaire about body esteem. A total of 960 children, 515 girls and 445 boys, participated in the first wave in 2000 and a total of 342 children, 171 girls and 171 boys participated in the second wave in 2010. The results showed a general stability in levels of body esteem for both girls and boys over the past 10 years. The gender differences, with boys being more satisfied with their appearance and weight compared to girls also seems to be stable over the years. In addition, the results also showed a somewhat positive development among the overweight girls with enhanced body esteem for the overweight girls compared to the non‐overweight girls during the ten years studied. Unfortunately, the same pattern was not found for overweight boys. For them the discrepancy in body esteem compared to non‐overweight boys, with the overweight boys being more dissatisfied, found in 2000 remained in 2010. 相似文献

We present a pilot study and two main studies that address the nature of stereotypes of social groups in Norway within the framework of the Stereotype Content Model (SCM). The first study focused on stereotypes of a wide range of groups across categories such as gender, age, religious conviction, socioeconomic and health status. The second study focused on stereotypes of immigrant groups. Participants (n = 244 and n = 63, respectively) rated the groups on perceived warmth, competence, status, and competition. Results from both studies support the applicability of the SCM in Norway and provides a unique insight into stereotypes of Norwegian social groups. 相似文献

Since 2009 the Evangelical Lutheran Church in America has worked to develop a survey that can reliably measure qualitative aspects of congregational vitality. This study describes the development of a survey that focuses on key missional outcomes. Congregation members and pastors from 73 congregations were surveyed. Exploratory factor analysis identified important differences in the way pastors and lay people understand concepts like mission resulting in the creation of separate scales for pastors and lay people. These scales describe congregational vitality in five areas. Lay scales describe a congregation’s connections with God, each other and the world while pastor scales describe their understanding of the congregation’s inner strength and faith in action outside the congregation. For each respondent, individual scale scores were averaged to create congregational scale scores. Congregational scale scores were then compared with each congregation’s annual statistics, key informant perceptions, and other items within the survey for validation. The result was a psychometrically sound instrument that helps congregations, synods and the denomination gain a more complete understanding of vitality. Implications for further research are discussed. 相似文献

Organizations have responded to ethical scandals in part by creating the Ethics and Compliance Officer (ECO) role to help insure employee ethical and legal behavior. Because ECO work is so fundamental to behavioral ethics in organizations and we know very little about it, we conducted a grounded theory study to learn more. We learned that, although most ECOs were hired to help their organizations respond to external legitimacy challenges, ECOs face major legitimacy challenges inside their organizations. Facilitating conditions may reduce these challenges and help ECOs reach internal legitimacy. But, we also found that ECOs engage in what we term legitimacy work that relies on a number of tactics to help them gain legitimacy in the eyes of their constituents. We tie our findings to the broader legitimacy literature and draw implications for the behavioral ethics literature. 相似文献

Across species, kin bond together to promote survival. We sought to understand the dyadic effect of exclusion by kin (as opposed to non‐kin strangers) on brain activity of the mother and her child and their subjective distress. To this end, we probed mother–child relationships with a computerized ball‐toss game Cyberball. When excluded by one another, rather than by a stranger, both mothers and children exhibited a significantly pronounced frontal P2. Moreover, upon kin rejection versus stranger rejection, both mothers and children showed incremented left frontal positive slow waves for rejection events. Children reported more distress upon exclusion than their own mothers. Similar to past work, relatively augmented negative frontal slow wave activity predicted greater self‐reported ostracism distress. This effect, generalized to the P2, was limited to mother‐ or child‐rejection by kin, with comparable magnitude of effect across kin identity (mothers vs. children). For both mothers and children, the frontal P2 peak was significantly pronounced for kin rejection versus stranger rejection. Taken together, our results document the rapid categorization of social signals as kin relevant and the specificity of early and late neural markers for predicting felt ostracism. 相似文献

Recording of event-related potentials (ERPs) is one of the best-suited technologies for examining brain function in human infants. Yet the existing software packages are not optimized for the unique requirements of analyzing artifact-prone ERP data from infants. We developed a new graphical user interface that enables an efficient implementation of a two-stage approach to the analysis of infant ERPs. In the first stage, video records of infant behavior are synchronized with ERPs at the level of individual trials to reject epochs with noncompliant behavior and other artifacts. In the second stage, the interface calls MATLAB and EEGLAB (Delorme & Makeig, Journal of Neuroscience Methods 134(1):9–21, 2004) functions for further preprocessing of the ERP signal itself (i.e., filtering, artifact removal, interpolation, and rereferencing). Finally, methods are included for data visualization and analysis by using bootstrapped group averages. Analyses of simulated and real EEG data demonstrated that the proposed approach can be effectively used to establish task compliance, remove various types of artifacts, and perform representative visualizations and statistical comparisons of ERPs. The interface is available for download from http://www.uta.fi/med/icl/methods/eeg.html in a format that is widely applicable to ERP studies with special populations and open for further editing by users. 相似文献

A critical question about the nature of human learning is whether it is an all-or-none or a gradual, accumulative process. Associative and statistical theories of word learning rely critically on the later assumption: that the process of learning a word’s meaning unfolds over time. That is, learning the correct referent for a word involves the accumulation of partial knowledge across multiple instances. Some theories also make an even stronger claim: Partial knowledge of one word–object mapping can speed up the acquisition of other word–object mappings. We present three experiments that test and verify these claims by exposing learners to two consecutive blocks of cross-situational learning, in which half of the words and objects in the second block were those that participants failed to learn in Block 1. In line with an accumulative account, Re-exposure to these mis-mapped items accelerated the acquisition of both previously experienced mappings and wholly new word–object mappings. But how does partial knowledge of some words speed the acquisition of others? We consider two hypotheses. First, partial knowledge of a word could reduce the amount of information required for it to reach threshold, and the supra-threshold mapping could subsequently aid in the acquisition of new mappings. Alternatively, partial knowledge of a word’s meaning could be useful for disambiguating the meanings of other words even before the threshold of learning is reached. We construct and compare computational models embodying each of these hypotheses and show that the latter provides a better explanation of the empirical data. 相似文献
