Nurturing Environments for Boys and Men of Color with Trauma Exposure

Boys and men of color are exposed to traumatic experiences at significantly higher rates than are other demographic groups. To understand and address the mental and behavioral health effects of trauma, including violent incidents, on this population, we review the literature showing the context for, outcomes of, and potential responses to trauma exposure. We present the existing research about the unique challenges and associated negative outcomes for boys and men of color, as well as identify the gaps in the literature. We present the potential nurturing responses by systems such as schools, law enforcement, and communities to trauma-exposed boys and men of color, and we describe evidence-based programs and practices that directly address trauma. Finally, we argue that, rather than using a deficit model, a model of optimal development can be used to understand how to support and protect boys and men of color through nurturing environments.     

Measurement Invariance of Personal Well-Being Index (PWI-8) Across 26 Countries

This report examines the measurement invariance of the Personal Well-being Index with 8 items (PWI-8). University students (N = 5731) from 26 countries completed the measure either through paper and pencil or electronic mode. We examined uni-dimensional structure of PWI and performed a Multi-group CFA to assess the measurement invariance across the 26 countries, using conventional approach and the alignment procedure. The findings provide evidence of configural and partial metric invariance, as well as partial scalar invariance across samples. The findings suggest that PWI-8 can be used to examine correlates of life satisfaction across all included countries, however it is impossible to compare raw scores across countries.     

Native and Non-native Speakers’ Brain Responses to Filled Indirect Object Gaps

We examined native and non-native English speakers’ processing of indirect object wh-dependencies using a filled-gap paradigm while recording event-related potentials (ERPs). The non-native group was comprised of native German-speaking, proficient non-native speakers of English. Both participant groups showed evidence of linking fronted indirect objects to the subcategorizing verb when this was encountered, reflected in an N400 component. Evidence for continued filler activation beyond the verb was seen only in the non-native group, in the shape of a prolonged left-anterior negativity. Both participant groups showed sensitivity to filled indirect object gaps reflected in a P600 response, which was more pronounced and more globally distributed in our non-native group. Taken together, our results indicate that resolving indirect object dependencies is a two-step process in both native and non-native sentence comprehension, with greater processing cost incurred in non-native compared to native comprehension.     

A kinematic examination of dual-route processing for action imitation

The dual-route model of imitation suggests that meaningful and meaningless actions are processed through either an indirect or a direct route, respectively. Evidence indicates that the direct route is more cognitively demanding since it relies on mapping visuospatial properties of the observed action on to a performed one. These cognitive demands might negatively influence reaction time and accuracy for actions performed following a meaningless action under time constraints. However, how meaningful and meaningless action imitation processing is reflected in movement kinematics is not yet clear. We wanted to confirm whether meaningless action performance incurs a reaction time cost, whether the cost is reflected in kinematics, and, more generally, to examine kinematic markers of emblematic meaningful and meaningless action imitation. We examined participants’ reaction time and wrist movements when they imitated emblematic meaningful or matched meaningless gestures in either blocks of the same action type or mixed blocks. Meaningless actions were associated with a greater correction period at the end of the movement, possibly reflecting a strategy designed to ensure accurate completion for less familiar actions under time constraints. Furthermore, in mixed blocks, trials following meaningless actions had a significantly increased reaction time, supporting previous claims that route selection for action imitation may be stimulus-driven. However, there was only convincing evidence for this effect with an interval of ~2,948ms, but not ~3,573ms or ~2,553ms, between movements. Future work motion-tracking the entire hand to assess imitation accuracy, and more closely examining the influence of duration between movements, may help to explain these effects.     

Counseling Customers: Emerging Roles for Genetic Counselors in the Direct-to-Consumer Genetic Testing Market

Individuals now have access to an increasing number of internet resources offering personal genomics services. As the direct-to-consumer genetic testing (DTC GT) industry expands, critics have called for pre- and post-test genetic counseling to be included with the product. Several genetic testing companies offer genetic counseling. There has been no examination to date of this service provision, whether it meets critics’ concerns and implications it may have for the genetic counseling profession. Considering the increasing relevance of genetics in healthcare, the complexity of genetic information provided by DTC GT, the mediating role of the internet in counseling, and potential conflicts of interest, this is a topic which deserves further attention. In this paper we offer a discourse analysis of ways in which genetic counseling is represented on DTC GT websites, blogs and other online material. This analysis identified four types of genetic counseling represented on the websites: the integrated counseling product; discretionary counseling; independent counseling; and product advice. Genetic counselors are represented as having the following roles: genetics educator; mediator; lifestyle advisor; risk interpreter; and entrepreneur. We conclude that genetic counseling as represented on DTC GT websites demonstrates shifting professional roles and forms of expertise in genetic counseling. Genetic counselors are also playing an important part in how the genetic testing market is taking shape. Our analysis offers important and timely insights into recent developments in the genetic counseling profession, which have relevance for practitioners, researchers and policy makers concerned with the evolving field of personal genomics.     

Language in dialogue: when confederates might be hazardous to your data

Experiments that aim to model language processing in spoken dialogue contexts often use confederates as speakers or addressees. However, the decision of whether to use a confederate, and of precisely how to deploy one, is shaped by researchers’ explicit theories and implicit assumptions about the nature of dialogue. When can a confederate fulfill the role of conversational partner without changing the nature of the dialogue itself? We survey the benefits and risks of using confederates in studies of language in dialogue contexts, identifying four concerns that appear to guide how confederates are deployed. We then discuss several studies that have addressed these concerns differently—and, in some cases, have found different results. We conclude with recommendations for how to weigh the benefits and risks of using experimental confederates in dialogue studies: Confederates are best used when an experimental hypothesis concerns responses to unusual behaviors or low-frequency linguistic forms and when the experimental task calls for the confederate partner to take the initiative as speaker. Confederates can be especially risky in the addressee role, especially if their nonverbal behavior is uncontrolled and if they know more than is warranted by the experimental task.     

Item Response Modeling of Paired Comparison and Ranking Data

The comparative format used in ranking and paired comparisons tasks can significantly reduce the impact of uniform response biases typically associated with rating scales. Thurstone's (1927, 1931) model provides a powerful framework for modeling comparative data such as paired comparisons and rankings. Although Thurstonian models are generally presented as scaling models, that is, stimuli-centered models, they can also be used as person-centered models. In this article, we discuss how Thurstone's model for comparative data can be formulated as item response theory models so that respondents' scores on underlying dimensions can be estimated. Item parameters and latent trait scores can be readily estimated using a widely used statistical modeling program. Simulation studies show that item characteristic curves can be accurately estimated with as few as 200 observations and that latent trait scores can be recovered to a high precision. Empirical examples are given to illustrate how the model may be applied in practice and to recommend guidelines for designing ranking and paired comparisons tasks in the future.     

Ecclesiology and Ethics

The author elaborates on the relation between tradition and the concept of 'invention' within doctrinal theory. Based on examinations of how this is reflected upon in selected doctrinal theories (Alister E. McGrath, Wolfhart Pannenberg and Oswald Bayer), the author discusses 'invention' in relation to adjacent theological issues. Diverging issues seem to be whether invention should be reserved for the object of theology (Bayer), or whether invention should be the task of systematic theology, especially in relation to the constant generation of new experiences (McGrath and Pannenberg). The author also asserts that the doctrinal theory of Bayer is inventive, even though not intended to be so. Thus, the question is how to work inventively within systematic theology, not whether to do so.     

Perfectionism,discrepancies, and depression: Testing the perfectionism social disconnection model in a short-term,four-wave longitudinal study

Perfectionistic concerns (i.e., negative reactions to failures, exaggerated concerns over others’ criticism and expectations, and nagging self-doubts) are linked to social disconnection and depressive symptoms. According to the perfectionism social disconnection model, perfectionistic concerns contribute to social disconnection (i.e., feeling rejected, excluded, and unwanted by others) which, subsequently, contributes to depressive symptoms. The social world is replete with chances for interpretations. In interpreting their social worlds, people high in perfectionistic concerns tend to perceive interpersonal discrepancies, a distressing form of social disconnection that involves perceptions of others as dissatisfied with them and as disapproving of them. These interpretations are also conceptualized as having depressing consequences for people high in perfectionistic concerns. This study tested whether perceived interpersonal discrepancies mediate the relation between perfectionistic concerns and depressive symptoms; 240 participants were recruited and this mediational model was tested with a four-wave, 4-week longitudinal design. Structural equation modeling with bootstrapped tests of mediation indicated the perfectionistic concerns-depressive symptoms relationship was mediated by interpersonal discrepancies (even after controlling for perfectionistic strivings). People high in perfectionistic concerns perceive others as dissatisfied with them and as disapproving of them. Feeling rejected, excluded, and unwanted by others, people high in perfectionistic concerns are vulnerable to depression.
