Word comprehension mediates the link between gesture and word production: Examining language development in infant siblings of children with autism spectrum disorder

Children's gesture production precedes and predicts language development, but the pathways linking these domains are unclear. It is possible that gesture production assists in children's developing word comprehension, which in turn supports expressive vocabulary acquisition. The present study examines this mediation pathway in a population with variability in early communicative abilities—the younger siblings of children with autism spectrum disorder (ASD; high‐risk infants, HR). Participants included 92 HR infants and 28 infants at low risk (LR) for ASD. A primary caregiver completed the MacArthur‐Bates Communicative Development Inventory (Fenson, et al., 1993) at 12, 14, and 18 months, and HR infants received a diagnostic evaluation for ASD at 36 months. Word comprehension at 14 months mediated the relationship between 12‐month gesture and 18‐month word production in LR and HR infants (ab = 0.263; p < 0.01). For LR infants and HR infants with no diagnosis or language delay, gesture was strongly associated with word comprehension (as = 0.666; 0.646; 0.561; ps < 0.01). However, this relationship did not hold for infants later diagnosed with ASD (a = 0.073; p = 0.840). This finding adds to a growing literature suggesting that children with ASD learn language differently. Furthermore, this study provides an initial step toward testing the developmental pathways by which infants transition from early actions and gestures to expressive language.     

Sensitive and tolerant raters differ in their magnitude estimates of extremely violent behaviors

A 2007 study indicated severity of violence of several behaviors can be rated consistently, such that an individual's average rating across the behaviors can serve as a measure of sensitivity to violence. However, violence-sensitive and violence-tolerant raters in that study gave similar high scale ratings of severity of violence for extremely violent behaviors such as murder and stabbing. In the present study an open-ended magnitude estimation response scale was used by 27 participants to examine impressions of the severity of violence of 38 behaviors. There was a positive correlation between estimates of severity for extreme physical violence and estimates for lower severity of violence. This result indicates that the earlier finding of apparent equivalence of sensitive and tolerant individuals did not signify agreement about extremely violent behaviors but was a ceiling effect arising from the closed-ended response scale used. Violence-sensitive and violence-tolerant individuals seem to have different attitudes toward all types of violence.     

Dynamics of the dyad: How mothers and infants co-construct interaction spaces during object play

Studies of dyadic interaction often examine infants’ social exchanges with their caregivers in settings that constrain their physical properties (e.g., infant posture, fixed seating location for infants and adults). Methodological decisions about the physical arrangements of interaction, however, may limit our ability to understand how posture and position shape them. Here we focused on these embodied properties of dyadic interaction in the context of object play. We followed 30 mother–infant dyads across the first year of life (at 3, 6, 9, and 12 months) and observed them during 5 min of play with a standard set of toys. Using an interval-based coding system, we measured developmental change in infant posture, how mothers and infants positioned themselves relative to one another, and how they populated interaction spaces with objects. Results showed that mother–infant dyads co-constructed interaction spaces and that the contributions of each partner changed across development. Dyads progressively adopted a broader spatial co-orientation during play (e.g., positioned at right angles) across the first year. Moreover, advances in infants’ postural skills, particularly increases in the use of independent sitting in real time, uniquely predicted change in dyadic co-orientation and infants’ actions with objects, independent of age. Taken together, we show that the embodied properties of dyadic object play help determine how interactions are physically organized and unfold, both in real time and across the first year of life.     

Attachment to God,depression and loss in late life: a longitudinal study

ABSTRACT

Prior research shows that being anxiously and avoidantly attached to God is associated with psychologically problematic outcomes including depressive feelings. However, a clear understanding of how these insecure attachments to God are associated with depressive feelings is still missing. Therefore, a longitudinal study among 329 nursing home residents aged 65–99 was set up to investigate the prospective relation between anxious and avoidant attachment to God and the experience of depressive feelings, as well as whether this relation is moderated by a loss experience. That is, the loss of close relatives can be particularly stressful in late life, challenging existing attachment relationships and placing older adults at risk for depression. Results confirm that insecure attachments to God are distinctly related to depressive feelings, but that this relation is not moderated by a loss experience. Our results also show that depressive feelings predicts attachment to God, instead of the other way around.     

Mindfulness in Context: A Historical Discourse Analysis

‘Mindfulness’ has become a buzzword, yet its meaning and origins have received relatively little critical consideration. This article places the current ‘mindfulness movement’ in context, examining the evolving discourse surrounding the concept of mindfulness. Through the first systematic etymology of the term, drawing from old Western and Buddhist writings, contemporary psychology and popular media, it is established that the contemporary understanding of mindfulness has been substantially simplified and divorced from its origins. However, quantitative data suggests that this manoeuvre was essential for the mainstreaming of the concept. Moreover, the resulting momentum has stimulated a new and dynamic discourse about the relationship between ‘secular’ mindfulness and Buddhism, sparking questions about ‘McMindfulness’, ‘stealth’ Buddhism and cultural imperialism. Therefore, this article argues that the recontextualisation of mindfulness created the scaffolding that supported the emergence of a deeper and more meaningful conversation about its implications for Buddhism and society that we see today.     

Functions of Memory Sharing and Mother-Child Reminiscing Behaviors: Individual and Cultural Variations

This study examined maternal beliefs about the functions of memory sharing and the relations between these beliefs and mother-child reminiscing behaviors in a cross-cultural context. Sixty-three European American and 47 Chinese mothers completed an open-ended questionnaire concerning their beliefs about the functions of parent-child memory sharing. They also engaged in a joint-reminiscing task with their child. European American mothers were more likely than Chinese mothers to report social (conversational and relationship maintenance) and teaching/problem solving functions. In addition, conversational functions were associated with increased maternal elaborativeness and evaluations during reminiscing, independent of culture. Results are discussed in light of the functional and cultural contexts of early autobiographical memory development.     

Human–Robot Interaction in the Context of Simulated Route Reconnaissance Missions

The goal of this research was to examine the ways in which human operators interact with simulated semiautonomous unmanned ground vehicles (UGVs), semiautonomous unmanned aerial vehicles (UAVs), and teleoperated UGVs (Teleop). Robotic operators performed parallel route reconnaissance missions with each platform alone and with all three platforms. When given all three platforms, participants failed to detect more targets than when given only the UAV or UGV; they were also less likely to complete their mission in the allotted time. Target detection during missions was the poorest with the Teleop alone, likely because of the demands of remote driving. Spatial ability was found to be a good predictor of target-detection performance. However, slowing sensor feed video frame rate or the imposition of a short response latency (250 ms) between Teleop control and Teleop reaction failed to affect target-detection performance significantly. Nevertheless, these video image manipulations did influence assessment of system usability.     

Developmental time course of the acquisition of sequential egocentric and allocentric navigation strategies

Navigation in a complex environment can rely on the use of different spatial strategies. We have focused on the employment of “allocentric” (i.e., encoding interrelationships among environmental cues, movements, and the location of the goal) and “sequential egocentric” (i.e., sequences of body turns associated with specific choice points) strategies during navigation. To investigate the developmental pattern of these two strategies in school-aged children, we used a virtual reality paradigm in which the spontaneous or imposed use of both strategies could be assessed. Our results showed an increase in spontaneous use of the allocentric strategy and also an increase in reliance on environmental landmarks with age. Although a majority of the children spontaneously used the sequential egocentric strategy, all age groups performed above chance when the allocentric strategy was imposed. Altogether, our findings suggest that young children are able to employ an allocentric strategy but that the nature of this allocentric strategy changes progressively in a complex cognitive representation between 5 and 10 years of age.     

Measuring Religious Attitudes in Secularized Western European Context: A Psychometric Analysis of the Post-Critical Belief Scale

Wulff's two-dimensional model of approaches to religion was an inspiration for the development of the Post-Critical Belief Scale (PCBS), an instrument measuring religious attitudes, that is, “paradigms of religious belief structure” in a secularized Western European context. The scale has been frequently used in psychological studies, has undergone psychometric analyses and modifications, and has been translated into several languages. The current study shows results of a psychometric analysis of the component structure of PCBS in different age groups over time using Clusterwise Simultaneous Component Analysis-Equal Cross-Product (SCA-ECP). The analysis was based on samples collected in Flanders (Belgium; N = 14,599). The one-cluster and two-cluster models yielded three components: Literal Affirmation, Literal Disaffirmation, and Symbolic Attitude, and there were no differences between age groups. In the two-cluster model, subtle differences between samples collected before and after 2002 were found, and these were related to two PCBS items referring to interpretation of Biblical stories. Our finding of a generalized Symbolic Attitude might be related to the changes in the approaches to religion in secularized Western Europe, and might capture the religious (dis-)belief of individuals who are open and tolerant to other religious systems, or alternatively, have become indifferent to them. Further cross-cultural and longitudinal studies are needed to better understand the religious attitudes in a secularized context, and the development of a new scale based on the paradigm of personal meaning systems is suggested     

Employability and Job Search after Compulsory Reemployment Courses: The Role of Choice,Usefulness, and Motivation

Compulsory reemployment courses aim to increase unemployed people's chances of reemployment by enhancing their employability and job search activities. However, the course outcomes vary greatly. This study examined the conditions and mechanisms that influence the outcomes of reemployment courses. In a two‐wave study of 643 participants, we assessed participants’ course experience (perceived choice and perceived usefulness), motivation for finding reemployment (internalisation), and employability and job search before and after the course. The results confirmed that a more internalised motivation was positively related to most course outcomes. Unexpectedly, perceived choice was unrelated to internalised motivation and course outcomes. Instead, high perceived choice was beneficial for motivation and some course outcomes only when the participants perceived the course to be useful for finding reemployment but was detrimental when they perceived the course to be useless. Perceived usefulness was also directly and positively related to the participants’ internalised motivation, which was in turn positively associated with most employability dimensions and job search activities after the course. Our results imply that the compulsory nature of reemployment courses may not be detrimental to people's motivation and course outcomes as long as they perceive the course to be useful for finding reemployment.
