Age of acquisition effects on the functional organization of language in the adult brain

Using functional magnetic resonance imaging (fMRI), we neuroimaged deaf adults as they performed two linguistic tasks with sentences in American Sign Language, grammatical judgment and phonemic-hand judgment. Participants’ age-onset of sign language acquisition ranged from birth to 14 years; length of sign language experience was substantial and did not vary in relation to age of acquisition. For both tasks, a more left lateralized pattern of activation was observed, with activity for grammatical judgment being more anterior than that observed for phonemic-hand judgment, which was more posterior by comparison. Age of acquisition was linearly and negatively related to activation levels in anterior language regions and positively related to activation levels in posterior visual regions for both tasks.     

Changes in infants' affect related to the onset of independent locomotion

Previous research suggests that after gaining several weeks of independent locomotor experience, infants may show both more negative and more positive affect toward parents. However, this prior work has been based largely on parent report, and no studies have used longitudinal or naturalistic methods to chart changes in infants’ affective expressions as they gain locomotor ability. Fifteen infants were observed at home before, during, and after learning to crawl in two naturalistic contexts, free play and dyadic play. Expressions of negative affect during free play decreased after the onset of crawling, but there was no change in expressions of positive affect. At the same time, however, mothers reported an increase in both negative and positive reactivity. These results are discussed in terms of the contexts typically assessed during observations and the different sensitivities of mothers to infants’ expressions of affect. Several lines of evidence point to a potential role for independent locomotion in the reorganization of affective expressions.     

Factor structure, measurement invariance and structural invariance of the MSCEIT V2.0

This study explored factor structure and measurement and structural invariance of the MSCEIT V2.0 across two age groups: 258 young (18-31 years) and 262 older adults (32-79 years). Results supported a three-factor solution reflecting the Experiential Emotional Intelligence area, and Understanding Emotions and Managing Emotions branches. There was evidence of measurement invariance of factor structure and factor loadings, and partial support for invariance of the intercepts. Comparisons of latent factor means suggested that older adults have significantly higher mean scores on two of the three factors: Understanding and Managing Emotions. Implications of the invariance tests and latent means analyses are discussed.     

Does money really matter? Estimating impacts of family income on young children's achievement with data from random-assignment experiments

Social scientists do not agree on the size and nature of the causal impacts of parental income on children's achievement. We revisit this issue using a set of welfare and antipoverty experiments conducted in the 1990s. We utilize an instrumental variables strategy to leverage the variation in income and achievement that arises from random assignment to the treatment group to estimate the causal effect of income on child achievement. Our estimates suggest that a $1,000 increase in annual income increases young children's achievement by 5%-6% of a standard deviation. As such, our results suggest that family income has a policy-relevant, positive impact on the eventual school achievement of preschool children.     

Can the absence of prejudice be more threatening than its presence? It depends on one's worldview

The present research used validated cardiovascular measures to examine threat reactions among members of stigmatized groups when interacting with members of nonstigmatized groups who were, or were not, prejudiced against their group. The authors hypothesized that people's beliefs about the fairness of the status system would moderate their experience of threat during intergroup interactions. The authors predicted that for members of stigmatized groups who believe the status system is fair, interacting with a prejudiced partner, compared with interacting with an unprejudiced partner, would disconfirm their worldview and result in greater threat. In contrast, the authors predicted that for members of stigmatized groups who believe the system is unfair, interacting with a prejudiced partner, compared with interacting with an unprejudiced partner, would confirm their worldview and result in less threat. The authors examined these predictions among Latinas interacting with a White female confederate (Study 1) and White females interacting with a White male confederate (Study 2). As predicted, people's beliefs about the fairness of the status system moderated their experiences of threat during intergroup interactions, indicated both by cardiovascular responses and nonverbal behavior. The specific pattern of the moderation differed across the 2 studies.     

Relationships between Machiavellianism, emotional intelligence and theory of mind in children

The current study investigates the associations of Machiavellianism (Mach) with trait and ability emotional intelligence (EI), and theory of mind (ToM) in 109 primary school children. Consistent with previous research with adults, negative associations were found between Mach and social and emotional understanding. Subsequent multiple regression analyses for girls showed that being more adept at emotional and social understanding does not lead them to manipulate others in social encounters. This was not the case for boys. These findings are discussed in relation to other social and individual difference variables that impact on Mach, particularly amongst boys.     

Positive Affectivity and Collective Efficacy as Moderators of the Relationship Between Perceived Politics and Job Satisfaction

This study explores the moderating potential of positive affectivity (PA) and perceived collective efficacy (PCE) on the relationship between 3 dimensions of politics perceptions and job satisfaction. We hypothesized that high levels of PA and PCE, in unison, would buffer the harmful effects of perceived politics on job satisfaction. Regression analyses for the 3 dimensions (i.e., general politics, go along to get along, and pay and promotion) yielded a significant finding for the PA × PCE × Go Along to Get Along 3-way interaction only. Consistent with our expectations, low PA-low PCE individuals were less satisfied with their jobs when levels of go-along-to-get-along politics increased. Contrary to our hypothesis, however, high PA-high PCE individuals reported a significant inverse relationship between perceived politics and job satisfaction. Implications of these findings and directions for future research are provided.     

Life-Satisfaction in Post-Soviet Russia and Ukraine

This paper fills a gap in the literature by looking at influences on the well-being of the citizens of Russia and Ukraine in the context of the triple shock – economic, political and social – that they experienced after 1991. The paper argues that lived experience – how people evaluate their living conditions – is as significant an influence on the welfare of citizens as are the actual conditions in which they live. The majority of the populations perceive the post-1991 economic and political changes negatively, and levels of general satisfaction and happiness are comparatively low. The findings suggest that objective economic factors, geographical/social location, health status and social context influence well-being, but also personal control and satisfaction with material circumstances, with health having a greater influence on happiness, while material circumstances and the evaluation of them have a greater influence on general satisfaction. The paper concludes by arguing for a model of reciprocal causation in which material factors provide the partially determining context for actions and are themselves influenced by happiness and satisfaction.     

Media and Metanoia: Documentary ‘Impact’ Through the Lens of Conversion

How do contemporary understandings of religious conversion and formation shed light on the “impact” and “effectiveness” of social change media? This paper evaluates three case studies, public television documentaries produced in the mid-1990s, to reflect on their social effect. Contemporary conversion theory provides a nuanced perspective with which to interpret the nature and circumstances under which social documentary—media created specifically so as to have a social effect—may in fact be said to have an “impact.” Innumerable media theorists have discredited market models where the uncritical television viewer gets off her couch straightaway and goes out to join a social movement in the same manner as she might buy a new brand of toothpaste, and yet an expectation of being able to demonstrate (often quantifiable) “results” insistently follows documentarians and public television outreach professionals. This “high-impact” model may be seen to be analogous to a “Road to Damascus” view of instant and permanent religious conversion, likewise discounted yet tenacious. It is an illuminating exercise to consider the operations of documentary media from the perspective of developmental conversion theorists such as Rambo, Tippett, Fowler, Lovland and Stark, and others. In this light, it is possible to understand both how these documentary case studies did create certain very particular kinds of change, as well as why most social documentaries, in truth, do not.     

A perceptual discrimination investigation of the own‐race effect and intergroup experience

Research over the past two decades has demonstrated that individuals are better at the recognition and discrimination of own‐ versus other‐race faces. Recent evidence, however, supports an own‐race effect at the level of perceptual encoding in adults. The current study examines the perceptual basis of the own‐race effect in secondary students from two racially segregated communities (White and South Asian). The contact hypothesis is investigated, as other‐race experience may influence other‐race face perception. Face stimuli were generated by morphing together South Asian and White faces along a linear continuum. In a same/different perceptual discrimination task participants judged whether face stimuli were physically identical to, or different from, the original faces. Results revealed a significant own‐race effect for the White participants only, wherein they were better at discriminating White relative to South Asian faces. Other‐race individuating experience was found to predict the own‐race effect, indicating that other‐race experience influences other‐race face perceptual expertise.
