Motivated cultural cognition: the impact of implicit cultural theories on dispositional attribution varies as a function of need for closure

The authors propose that need for closure (NFC) leads attributors to respond to an ambiguous social event by increasing reliance on implicit theories received from acculturation. Hence, the influence of NFC should be shaped by chronically accessible knowledge structures in a culture, and, likewise, the influence of culture should be moderated by epistemic motives such as NFC. The specific hypotheses drew on past findings that North American and Chinese attributors possess differing implicit social theories, North Americans conceiving of individuals as autonomous agents and Chinese conceiving of groups as autonomous. The present studies found the predicted pattern that among North American participants, NFC increased attributions to personal but not group dispositions. Among Chinese participants, NFC increased attributions to group but not personal dispositions. The findings are discussed in light of an emerging dynamic account of culture and cognition.     

Specificity of auditory implicit and explicit memory: Is perceptual priming for environmental sounds exemplar specific?

Previous research (Stuart & Jones, 1995) has suggested that identification of environmental sounds may be mediated by abstract sound recognition units. This article reports the results of four repetition priming experiments that find evidence to the contrary. Participants attempted to identify environmental sounds from the initial sound stems (Experiments 1 and 2) or when the sounds were embedded in white noise (Experiments 3 and 4). Repetition of an identical exemplar sound led to more priming than did exposure to a different exemplar, provided that the perceptual difference between the two different exemplars was sufficiently large. Such an exemplar specificity effect was independent of the depth of prior encoding. A similar exemplar specificity effect was also found in explicit stem-cued recall (Experiments 1 and 2) and recognition (Experiment 3). Depth of encoding dissociated performance on tests of repetition priming and explicit memory. These results suggest that a significant amount of specific information is remembered, both implicitly and explicitly, to characterize individual exemplars of a sound category.     

The Reduced RUM as a Logit Model: Parameterization and Constraints

Cognitive diagnosis models (CDMs) for educational assessment are constrained latent class models. Examinees are assigned to classes of intellectual proficiency defined in terms of cognitive skills called attributes, which an examinee may or may not have mastered. The Reduced Reparameterized Unified Model (Reduced RUM) has received considerable attention among psychometricians. Markov Chain Monte Carlo (MCMC) or Expectation Maximization (EM) are typically used for estimating the Reduced RUM. Commercial implementations of the EM algorithm are available in the latent class analysis (LCA) routines of Latent GOLD and Mplus, for example. Fitting the Reduced RUM with an LCA routine requires that it be reparameterized as a logit model, with constraints imposed on the parameters. For models involving two attributes, these have been worked out. However, for models involving more than two attributes, the parameterization and the constraints are nontrivial and currently unknown. In this article, the general parameterization of the Reduced RUM as a logit model involving any number of attributes and the associated parameter constraints are derived. As a practical illustration, the LCA routine in Mplus is used for fitting the Reduced RUM to two synthetic data sets and to a real-world data set; for comparison, the results obtained by using the MCMC implementation in OpenBUGS are also provided.     

The Association Between Age and Ethics-Related Issues in Using Social Media for HIV Prevention in Peru

Little research has focused on the ethical issues around using social media for HIV prevention in low- and middle-income countries, such as Peru. This study surveyed participants from the HOPE social media HIV intervention in Peru to assess their experiences and perceptions of ethical issues in the study and the impact of age on their experiences and perceptions. This study found that, compared to younger participants, older participants were more likely to express higher levels of understanding of the consent form and trust that other participants were real. Older participants also reported being less likely to benefit from learning about their HIV status. Findings suggest that age plays a role in participants’ experiences in a social-media-based HIV intervention.     

Helpful but insufficient: Incremental theory on challenge-confronting tendencies for students who fear being laughed at

Previous studies have demonstrated that endorsing an incremental theory of intelligence is helpful in motivating students to confront challenges. We used a survey to examine whether this theory could predict greater challenge-confronting tendencies for students with relatively high gelotophobia (i.e., the fear of being laughed at) and explore the possible underlying processes. A total of 264 senior high school students completed the measures of gelotophobia, implicit theories of intelligence, challenge-confronting tendencies, perceived value and feelings of being threatened in confronting challenges, and their self-perceived general ability. The results showed that endorsing an incremental theory predicted greater perceived value in confronting challenges and stronger challenge-confronting tendencies for students with relatively low gelotophobia. However, for those with relatively high gelotophobia, although this theory also predicted greater perceived value in confronting challenges, it was unrelated to challenge-confronting tendencies. Thus, endorsing an incremental theory is helpful but insufficient in motivating high gelotophobia students to exhibit stronger challenge-confronting tendencies.     

Cognitive Diagnosis for Small Educational Programs: The General Nonparametric Classification Method

The focus of cognitive diagnosis (CD) is on evaluating an examinee’s strengths and weaknesses in terms of cognitive skills learned and skills that need study. Current methods for fitting CD models (CDMs) work well for large-scale assessments, where the data of hundreds or thousands of examinees are available. However, the development of CD-based assessment tools that can be used in small-scale test settings, say, for monitoring the instruction and learning process at the classroom level has not kept up with the rapid pace at which research and development proceeded for large-scale assessments. The main reason is that the sample sizes of the small-scale test settings are simply too small to guarantee the reliable estimation of item parameters and examinees’ proficiency class membership. In this article, a general nonparametric classification (GNPC) method that allows for assigning examinees to the correct proficiency classes with a high rate when sample sizes are at the classroom level is proposed as an extension of the nonparametric classification (NPC) method (Chiu and Douglas in J Classif 30:225–250, 2013). The proposed method remedies the shortcomings of the NPC method and can accommodate any CDM. The theoretical justification and the empirical studies are presented based on the saturated general CDMs, supporting the legitimacy of using the GNPC method with any CDM. The results from the simulation studies and real data analysis show that the GNPC method outperforms the general CDMs when samples are small.     

Blazing the trail versus trailing the group: Culture and perceptions of the leader’s position

Research suggests that power triggers assertive action. However, people from different cultures might expect different types of action from powerful individuals such as leaders. In comparing cultural differences in leadership imagery, we find that Americans represent leaders standing ahead of groups, whereas Asians also represent leaders behind groups. We propose that front versus back positions embody two faces of leader action: individual assertion versus group-focused action. Studies 1a and 1b respectively employed etic and emic methods to demonstrate that Singaporeans were more likely than Americans to represent leaders behind groups. In Study 2, Singaporeans evaluated back leaders more favorably than Americans did, and group focus mediated cultural differences. Simulating the conditions under which cultural differences arise, Study 3 demonstrates that a primarily Western managerial sample primed with threat (versus opportunity) preferred back leaders. By describing cultural variations in imagery, we reveal more nuanced implicit theories of leader action.     

Asians as the model minority: Implications for US Government's policies

Asian Americans are often perceived as a 'model minority'– an ethnic minority that are high achieving, hardworking, self-reliant, law-abiding, as well as having few social and mental health problems. Although the impact of the model minority image on the US government's redistributive policies is a widely contested topic in public discourses, there has been little research on the association between the model minority image, people's worldviews, and attitudes towards the US government's redistributive policies. In an experiment that measured American participants' worldviews and manipulated the salience of the model minority image, we have demonstrated that those who believed in a malleable social reality were relatively unsupportive of government policies that help the Asian American ( vs African American) communities. Theoretical and practical implications of this finding are discussed.
