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

The study investigated whether successful transfer of game-based cognitive improvements to untrained tasks might be modulated by preexisting neuro-developmental factors, such as genetic variability related to the catechol-O-methyltransferase (COMT)—an enzyme responsible for the degradation of dopamine. The COMT Val158Met genotype may differentially affect cognitive stability and flexibility, and we hypothesized that Val/Val homozygous individuals (who possess low prefrontal dopamine levels) show more pronounced cognitive flexibility than Met/-carriers (who possess high prefrontal dopamine levels). We trained participants, genotyped for the COMT Val158Met polymorphism on playing “Half-Life 2”, a first-person shooter game which has been shown to improve cognitive flexibility. Pre-training (baseline) and post-training measures of cognitive flexibility were acquired by means of a task-switching paradigm. As expected, Val/Val homozygous individuals showed larger beneficial transfer effects than Met/-carriers. Our findings support the idea that genetic predisposition modulates transfer effects and that playing first-person shooter games promotes cognitive flexibility in individuals with a suitable genetic predisposition. 相似文献

The value‐action gap poses a considerable challenge to normative environmental ethics. Because of the wide array of empirical research results that have become available in the fields of environmental psychology, education, and anthropology, ethicists are at present able to take into account insights on what effectively motivates proenvironmental behavior. The emotional aspect apparently forms a key element within a transformational process that leads to an internalization of nature within one's identity structure. We compare these findings with studies on environmental activists, which appear to a significantly lesser degree hampered by the value‐action gap, thereby attempting to understand what provides them with the drive to act more consistently on their moral attitudes. Hermeneutics is found to play a crucial role in the processes that lead to lasting and consistent motivation toward proenvironmental behavior. An empirically informed hermeneutical approach could therefore provide a promising impetus for contemporary environmental ethics. 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

Building on the work by Barrett-Lennard (Carl Rogers’ helping system: Journey & substance. Sage, London 1998) and Wood et al. (J Couns Psychol 55:385–399 2008), this study describes the development and validation of a theory-based measure of state authenticity at work, the Individual Authenticity Measure at Work (IAM Work). Even though this construct is obviously relevant to the work context (e.g., as regards issues of work relations, leadership and well-being), none of the instruments currently available focuses on authenticity in the area of work and organizational psychology. A total sample of 646 participants was divided in two equal sized subsamples. Exploratory factor analysis supported the underlying tripartite construct of authenticity at work, resulting in the subscales authentic living, self-alienation, and accepting external influences. Confirmatory factor analysis confirmed the tripartite construct and showed good psychometric properties of the state-focused measure of authenticity at work. Finally, correlation analysis showed that each subscale and the total score of authenticity was positively related to commonly used work outcomes such as job satisfaction, in-role performance, and work engagement. This study concludes that the IAM Work is a reliable and valid measure of state authenticity at work. Implications for future research and practice are discussed. 相似文献

This article describes a generalized longitudinal mixture item response theory (IRT) model that allows for detecting latent group differences in item response data obtained from electronic learning (e-learning) environments or other learning environments that result in large numbers of items. The described model can be viewed as a combination of a longitudinal Rasch model, a mixture Rasch model, and a random-item IRT model, and it includes some features of the explanatory IRT modeling framework. The model assumes the possible presence of latent classes in item response patterns, due to initial person-level differences before learning takes place, to latent class-specific learning trajectories, or to a combination of both. Moreover, it allows for differential item functioning over the classes. A Bayesian model estimation procedure is described, and the results of a simulation study are presented that indicate that the parameters are recovered well, particularly for conditions with large item sample sizes. The model is also illustrated with an empirical sample data set from a Web-based e-learning environment. 相似文献

Performance on visual working memory tasks decreases as more items need to be remembered. Over the past decade, a debate has unfolded between proponents of slot models and slotless models of this phenomenon (Ma, Husain, Bays (Nature Neuroscience 17, 347-356, 2014). Zhang and Luck (Nature 453, (7192), 233-235, 2008) and Anderson, Vogel, and Awh (Attention, Perception, Psychophys 74, (5), 891-910, 2011) noticed that as more items need to be remembered, “memory noise” seems to first increase and then reach a “stable plateau.” They argued that three summary statistics characterizing this plateau are consistent with slot models, but not with slotless models. Here, we assess the validity of their methods. We generated synthetic data both from a leading slot model and from a recent slotless model and quantified model evidence using log Bayes factors. We found that the summary statistics provided at most 0.15 % of the expected model evidence in the raw data. In a model recovery analysis, a total of more than a million trials were required to achieve 99 % correct recovery when models were compared on the basis of summary statistics, whereas fewer than 1,000 trials were sufficient when raw data were used. Therefore, at realistic numbers of trials, plateau-related summary statistics are highly unreliable for model comparison. Applying the same analyses to subject data from Anderson et al. (Attention, Perception, Psychophys 74, (5), 891-910, 2011), we found that the evidence in the summary statistics was at most 0.12 % of the evidence in the raw data and far too weak to warrant any conclusions. The evidence in the raw data, in fact, strongly favored the slotless model. These findings call into question claims about working memory that are based on summary statistics. 相似文献

A sample of stranger rape offences (n = 271) registered in the Dutch Violence Crime Linkage Analysis System database in the Netherlands between 1997 and 2007 was studied with the objective of developing statistical models, which give an indication of the probability of basic offender characteristics. Observable crime characteristics concerning the modus operandi, interaction between the offender and the victim, violence, precautionary measures, and sexual behaviours were selected in the dataset. Offender characteristics were selected based on their usefulness for the police organisation in narrowing the scope of a criminal investigation. Spatial behaviour, criminal history, and living situation of the offender were selected. From the predictive models, four out of five achieved a correct rate of over 70%, and all models predicted better than the best guess method. The proposed models for distance and prior convictions for violence seem particularly promising. Both these models show an improvement of correctly predicted offender characteristics of more than 20 percentile points compared with that which could have been estimated based on the average in the total sample. The predictive value of the models needs to be tested further with ‘new offences’, which were not used to construct the model. In general, the current study supports the finding that crime characteristics can be used to get an indication of the probability of certain offender characteristics. Nevertheless, for an understanding of the relationship between the crime characteristics and offender characteristics, a further development of a theoretical framework is urgently necessary.

The first goal of this study was to examine young children's developing narrative comprehension abilities using theory-based, authentic measures of comprehension processes. The second goal was to examine the relations among young children's comprehension abilities and other early reading skills. Children ages 4 and 6 listened to or watched two authentic narratives. We measured their comprehension of these narratives as well as vocabulary and skills associated with word decoding. The results revealed that even the younger children were sensitive to the underlying structure of the narratives and that this sensitivity increased with age. Measures of narrative comprehension were not consistently correlated with skills associated with word decoding, such as phonological awareness. The results are discussed in terms of theoretical models of comprehension and of reading development. Practical implications of the findings are also explored. 相似文献
