Experience with research paradigms relates to infants' direction of preference.

Interpreting and predicting direction of preference in infant research has been a thorny issue for decades. Several factors have been proposed to account for familiarity versus novelty preferences, including age, length of exposure, and task complexity. The current study explores an additional dimension: experience with the experimental paradigm. We reanalyzed the data from 4 experiments on artificial grammar learning in 12-month-old infants run using the head-turn preference procedure (HPP). Participants in these studies varied substantially in their number of laboratory visits. Results show that the number of HPP studies is related to direction of preference: Infants with limited experience with the HPP setting were more likely to show familiarity preferences than infants who had amassed more experience with this paradigm. This evidence has important implications for the interpretation of experimental results: Experience with a given method or, more broadly, with the laboratory environment may affect infants' patterns of preferences.

Network structure reveals clusters of associations between childhood adversities and development outcomes.

Exposure to childhood adversity is common and associated with a host of negative developmental outcomes. The most common approach used to examine the consequences of adversity exposure is a cumulative risk model. Recently, we have proposed a novel approach, the dimensional model of adversity and psychopathology (DMAP), where different dimensions of adversity are hypothesized to impact health and well-being through different pathways. We expect deprivation to primarily disrupt cognitive processing, whereas we expect threat to primarily alter emotional reactivity and automatic regulation. Recent hypothesis-driven approaches provide support for these differential associations of deprivation and threat on developmental outcomes. However, it is not clear whether these patterns would emerge using data-driven approaches. Here we use a network analytic approach to identify clusters of related adversity exposures and outcomes in an initial study (Study 1: N = 277 adolescents aged 16-17 years; 55.1% female) and a replication (Study 2: N = 262 children aged 8-16 years; 45.4% female). We statistically compare our observed clusters with our hypothesized DMAP model and a clustering we hypothesize would be the result of a cumulative stress model. In both samples we observed a network structure consistent with the DMAP model and statistically different than the hypothesized cumulative stress model. Future work seeking to identify in the pathways through which adversity impacts development should consider multiple dimensions of adversity.

Manifesto for new directions in developmental science.

Although developmental science has always been evolving, these times of fast-paced and profound social and scientific changes easily lead to disorienting fragmentation rather than coherent scientific advances. What directions should developmental science pursue to meaningfully address real-world problems that impact human development throughout the lifespan? What conceptual or policy shifts are needed to steer the field in these directions? The present manifesto is proposed by a group of scholars from various disciplines and perspectives within developmental science to spark conversations and action plans in response to these questions. After highlighting four critical content domains that merit concentrated and often urgent research efforts, two issues regarding "how" we do developmental science and "what for" are outlined. This manifesto concludes with five proposals, calling for integrative, inclusive, transdisciplinary, transparent, and actionable developmental science. Specific recommendations, prospects, pitfalls, and challenges to reach this goal are discussed.

A primer on investigating the role of the microbiome in brain and cognitive development.

Incorporating information regarding the gut microbiota into psychobiological research promises to shed new light on how individual differences in brain and cognitive development emerge. However, the investigation of the gut-brain axis in development is still in its infancy and poses several challenges, including data analysis. Considering that the gut microbiome is an eco-system containing millions of bacteria, one needs to utilize a breadth of methodologies and data analytic techniques. The present review serves two purposes. First, this review will inform developmental psychobiology researchers about the emerging study of the gut-brain axis in development and second, this review will propose methodologies and data analytic strategies for integrating microbiome data in developmental research.

A meta-analysis of the association between substance use and emerging adult development using the IDEA scale.

BACKGROUND AND OBJECTIVES: Much debate exists surrounding Arnett's theory of emerging adulthood in terms of its breadth and application. Researchers have attempted to capture dimensions of emerging adulthood (eg, experimentation, negativity/instability, other-focus, self-focus, and feeling in-between) through self report assessment, using variations of the Inventory of the Dimensions of Emerging Adulthood or IDEA. Results from studies investigating this relationship have been mixed. We conducted a meta-analysis on the association between substance use and the IDEA. METHOD: Data were extracted to calculate correlational associations with substance use as well as typical moderators found in the literature. Twelve studies were meta-analyzed. RESULTS: We found small associations (range: ρ = -.03 to .15; d = .06 to 30) between the IDEA scores and substance use. We found higher severity (dependence diagnosis) of participants yielded larger associations across all dimensions (ρ = .16), and proportion of college students to be a subscale-specific moderator (experimentation, negativity/instability, other-focus, self-focus, and feeling in-between). Alcohol use outcomes also provided larger subscale-specific associations (experimentation, negativity/instability, other-focus, self-focus). CONCLUSIONS: The dimensions of emerging adulthood may be less effective in predicting substance use among non-college samples and those studies focusing on drug use. Further research should prioritize exploring variation in the transition to emerging adulthood among non-college samples and the longitudinal associations between IDEA and substance use. SCIENTIFIC SIGNIFICANCE: Important contributions include the modest association between IDEA and substance use as well as specific participant characteristics that amplify or mitigate the association between IDEA and substance use.

Structural developmental psychology and health promotion in the third age.

In response to the ever-increasing longevity in Western societies, old age has been divided into two different periods, labelled the third and fourth age. Where the third age, with its onset at retirement, mostly involves positive aspects of growing old, the fourth age involves functional decline and increased morbidity. This article focuses on the entry to the third age and its potential for health promotion initiatives. Well-being is an important factor to emphasize in such health promotion, and this article views the lifestyle of third agers as essential for their well-being. The structural developmental theory of Robert Kegan delineates how a person's way of knowing develops throughout the life course. This theory is an untapped and salient perspective for health promotion initiatives in the third age. This article outlines Kegan's approach as a tool for developing psychologically spacious health promotion, and suggests future directions for research on the topic.

Brief note: Applying developmental intergroup perspectives to the social ecologies of bullying: Lessons from developmental social psychology.

Over the past decades, the field of bullying research has seen dramatic growth, notably with the integration of the social-ecological approach to understanding bullying. Recently, researchers (Hymel et al., 2015; Hawley & Williford, 2015) have called for further extension of the field by incorporating constructs of group processes into our investigation of the social ecologies of bullying. This brief note details the critical connections between power, social identity, group norms, social and moral reasoning about discrimination and victimization, and experiences of, evaluations of, and responses to bullying. The authors highlight a parallel development in the bridging of developmental social-ecological and social psychological perspectives utilized in the field of social exclusion that provides a roadmap for extending the larger field of bullying research. This article is part of a Special Issue entitled [VSI: Bullying] IG000050.

Publication patterns in developmental psychology: Trends and social networks.

Interest in publication patterns has been steady. Journals have instituted policies in an effort to curb bias and provide globally representative research. This study aimed to examine if publication patterns were present in two developmental psychology journals. It also explored the social networks of prominent authors and the prevalence of informal author-editor relationships, searching for any potential power groups. Data were taken from empirical articles published between 2005 and 2014 in Child Development (CD) and The International Journal of Early Childhood (IJEC) data points were geographical authorship affiliation, informal author relationships as established by co-publishing, and connections to journal editors via identical affiliation. Results confirmed the previously established North American dominance in published research. In CD a strongly interlinked social network was identified between authors over the 10 years, with 15 chief influentialists binding groups of authors together. Results suggest that patterns are still present in published research in the realm of developmental psychology. To conclude, the potential implications of these patterns within developmental psychology are presented.

[Adaptation and validation of the neurological soft sign's scale of Krebs et al. to children]. / Adaptation et validation d'une échelle des signes neurologiques mineurs chez l'enfant.

BACKGROUND: Neurological soft signs (NSS) include anomalies in motor integration, coordination, sensory integration and lateralization and could be endophenotypic markers in autism spectrum disorders (ASD). Their characterization provides a more precise phenotype of ASD and more homogeneous subtypes to facilitate clinical and genetic research. Few scales for NSS have been adapted and validated in children including children with ASD. Our objective was to perform an adaptation to the child of a scale assessing neurological soft signs and a validation study in both general and clinical populations. METHODS: We have selected the NSS scale of Krebs et al. (2000) already validated in adults. It encompasses 5 dimensions: motor coordination, motor integration, sensory integration, involuntary movement, laterality. After a preliminary study that examined 42 children, several changes have been made to the original version to adapt it to the child and to increase its feasibility, particularly in children with ASD. Then we conducted a validation study by assessing the psychometric properties of this scale in a population of 86 children including 26 children with ASD (DSM 5 Criteria) and 60 typically developing children. Children's ages ranged between 6 and 12 years, and patients and controls were matched for gender, age and intelligence. Patients were assessed using the Autism diagnostic Interview-revised and the Childhood Autism Rating Scale to confirm diagnosis. Typically developing children were assessed using the semi-structured Mini International Neuropsychiatric Interview for Children and Adolescents to eliminate any psychiatric disorder. All children with neurological pathologies (history of cerebral palsy, congenital anomaly of the central nervous system, epilepsy, tuberous sclerosis, neurofibromatosis, antecedent of severe head trauma) and obvious physical deformities or sensory deficits that could interfere with neurological assessment were excluded from the study. Both patients and controls were assessed using the Raven Progressive Matrices to exclude intellectual disability, and the adapted Krebs' scale for the assessment of NSS. RESULTS: Adaptation of the scale consisted of a modification in the order of items, in the use of concrete supports for the assessment of laterality and in the elimination of item constructive praxis. The internal consistency was good with a Cronbach alpha of 0.87. Inter-rater reliability was good, kappa coefficient was greater than 0.75 for 16 items, 3 items had a kappa value between 0.74 and 0.60, only 1 item had a kappa coefficient between 0.4 and 0.59. Good inter-rater reliability was also checked for the total score with a value of intra-class correlation coefficient (ICC) of 0.91. Principal component analysis found five factors accounting for 62.96 % of the total variance. About the comparison between patients and controls, significant differences were found for NSS total score (P=0.000) and all subscores. CONCLUSION: The adaptation for children of the Krebs et al.' NSS scale proved to be valid, especially in children with ASD.

What would Batman do? Self-distancing improves executive function in young children.

This experimental research assessed the influence of graded levels of self-distancing - psychological distancing from one's egocentric perspective - on executive function (EF) in young children. Three- (n = 48) and 5-year-old (n = 48) children were randomly assigned to one of four manipulations of distance from the self (from proximal to distal: self-immersed, control, third person, and exemplar) on a comprehensive measure of EF. Performance increased as a function of self-distancing across age groups. Follow-up analyses indicated that 5-year-olds were driving this effect. They showed significant improvements in EF with increased distance from the self, outperforming controls both when taking a third person perspective on the self and when taking the perspective of an exemplar other (e.g., Batman) through role play. Three-year-olds, however, did not show increased EF performance as a function of greater distance from the self. Preliminary results suggest that developments in theory of mind might contribute to these age-related differences in efficacy. These findings speak to the importance of psychological distancing in the expression of conscious control over thought and action from a young age and suggest a promising new avenue for early EF intervention.

Social competence in pediatric brain tumor survivors: application of a model from social neuroscience and developmental psychology.

Pediatric brain tumor (BT) survivors are at risk for psychosocial late effects across many domains of functioning, including neurocognitive and social. The literature on the social competence of pediatric BT survivors is still developing and future research is needed that integrates developmental and cognitive neuroscience research methodologies to identify predictors of survivor social adjustment and interventions to ameliorate problems. This review discusses the current literature on survivor social functioning through a model of social competence in childhood brain disorder and suggests future directions based on this model. Interventions pursuing change in survivor social adjustment should consider targeting social ecological factors.

The Relationship Between the Accumulated Number of Role Transitions and Hard Drug Use among Hispanic Emerging Adults.

Emerging adults (ages 18 to 25) who experience multiple role transitions in a short period of time may engage in hard drug use as a maladaptive coping strategy to avoid negative emotions from stress. Given the collectivistic values Hispanics encounter growing up, they may experience additional role transitions due to their group-oriented cultural paradigm. This study examined whether those who experience many role transitions are at greater risk for hard drug use compared to those who experience few transitions among Hispanic emerging adults. Participants completed surveys indicating their hard drug use in emerging adulthood, role transitions in the past year of emerging adulthood, age, gender, and hard drug use in high school. Simulation analyses indicated that an increase in the number of role transitions, from 0 to 13, was associated with a 14% (95% CI, 4 to 29) higher probability of hard drug use. Specific role transitions were found to be associated with hard drug use, such as starting to date or experiencing a breakup. Intervention/prevention programs may benefit from acknowledging individual reactions to transitions in emerging adulthood, as these processes may be catalysts for personal growth where identities are consolidated and decisions regarding hard drug use are formed.

Mentalization and Dialectical Behavior Therapy.

Dialectical Behavior Therapy (DBT) and Mentalization-Based Treatment (MBT) are two approaches to the treatment of borderline personality disorder (BPD). While DBT has the most empirical support, MBT has a small but significant evidence base. Dialectical behavior therapy synthesizes behaviorism, mindfulness, and dialectics, while MBT is conceptually anchored in psychoanalysis, attachment theory, cognitive neuroscience, and developmental psychopathology. While coming from strikingly different orientations, DBT and MBT therapists share more interventions and stances than one might suppose. The central purported active ingredient of MBT is the capacity to mentalize, which is crucial for the formation of secure attachment, and this ability is thought to be weak and unstable in individuals with borderline personality disorder. This article explores the question of whether or not mentalizing is already present in DBT practice, whether it would be compatible with DBT conceptually and practically, and whether a focus on mentalizing would be of use to the DBT therapists and their patients.

An Instance of Emotional Absence of a Father Traumatized by War-Clinical Material and Musical Illustration.

In his minor essay from 1914, Some Reflections on Schoolboy Psychology, Freud placed immense significance upon the father-son relationship as enabling or inhibiting the individual quest towards a mature, separate, and healthy development. In this essay, I will explore Freud's observations to illuminate the journey taken by Assaff, a 34-year old man who, during the early stages of his adolescence, had a father who was emotionally absent due a traumatic experience during his military service in the Israeli Defense Forces. Through transference work, the impact of the emotional absence will be shown. I will demonstrate how the boy was able unconsciously to use the music of Tommy, a rock opera by the British band The Who, as a transitional object. I will show how that piece of music provided Assaff with the sense of hope that helped during the darker times of his adolescent.

New directions for the study of within-individual variability in development: the power of "N = 1".

This article provides an introduction to the idiographic approach ("N = 1" research) in developmental psychology and an overview of methodological and statistical techniques employed to address the study of within-individual variability in development. Through a popularization of the idiographic approach and associated statistical techniques, but also through technical advances in the apparatus used to produce single-case intensive longitudinal data, the "power" of "N = 1" is becoming increasingly tangible and may challenge, or supplement, established paradigms in nomothetic (group-level) developmental psychology.

AINSWORTH'S STRANGE SITUATION PROCEDURE: THE ORIGIN OF AN INSTRUMENT.

The American-Canadian psychologist Mary Ainsworth (1913-1999) developed the Strange Situation Procedure (SSP) to measure mother-child attachment and attachment theorists have used it ever since. When Ainsworth published the first results of the SSP in 1969, it seemed a completely novel and unique instrument. However, in this paper we will show that the SSP had many precursors and that the road to such an instrument was long and winding. Our analysis of hitherto little-known studies on children in strange situations allowed us to compare these earlier attempts with the SSP. We argue that it was the combination of Ainsworth's working experience with William Blatz and John Bowlby, her own research in Uganda and Baltimore, and the strong connection of the SSP with attachment theory, that made the SSP differ enough from the other strange situation studies to become one of the most widely used instruments in developmental psychology today.

Some long-standing and emerging research lines in Africa.

Early research on child development in Africa was dominated by expatriates and was primarily addressed to the topics of testing the cross-cultural validity of theories developed "in the West," and the search for universals. After a brief review of the outcome of that research, we propose two additional types of motivation that seem important to us as African researchers begin to take the lead in articulating research agendas for the study of child development in Africa: articulating the contextual relevance and practical usefulness of developmental psychology in Africa; and making developmental psychology intelligible to local audiences. We highlight two major challenges for African societies in this era that call for attention by the emerging field of African child development research: linguistic hegemony and its effects on research and schooling; and the process of indigenization. We end with a preview of chapters in the rest of the volume.

Disruptive Behavior Disorders: The Challenge of Delineating Mechanisms in the Face of Heterogeneity.

Causal pathways to disruptive behavior disorders, even within the same diagnostic category, are varied. Both equifinality and multifinality pose considerable challenges to uncovering underlying mechanisms and understanding varied developmental trajectories associated with disruptive behavior disorders. Uncovering genetic causes requires improved granularity in how we operationalize presentation and developmental trajectories associated with disruptive behavior disorders. If we want to integrate the study of genetic, environmental, and neurocognitive factors within a longitudinal framework, we need to improve measurement. Furthermore, brain changes associated with disruptive behavior disorders should not simply be understood as outcomes of genetic and environmental influences, but also as factors that reciprocally influence future social environments over time in ways that are important in contributing to risk and resilience. Advancing the field with regard to these challenges will result in more truly integrated investigation of disruptive behavior disorders, which holds the promise of improving our ability to develop more effective preventive and intervention approaches.

Early Parenting Intervention Effects on Brain Responses to Maternal Cues Among High-Risk Children.

OBJECTIVE: Early adversity is correlated with increased risk for negative outcomes, including psychopathology and atypical neurodevelopment. The authors aimed to test the causal impact of an early parenting intervention (Attachment and Biobehavioral Catch-Up; ABC) on children's neural processing of parent cues and on psychosocial functioning in a longitudinal randomized clinical trial. METHODS: Participants (N=68, mean age, 10.0 years [SD=0.8 years]) were 46 high-risk children whose parents were randomly assigned to receive either the ABC intervention (N=22) or a control intervention (N=24) while the children were infants, in addition to a comparison sample of low-risk children (N=22). During functional MRI scanning, children viewed pictures of their own mothers and of a stranger. RESULTS: Children in the ABC condition showed greater maternal cue-related activation than children in the control condition in clusters of brain regions, including the precuneus, the cingulate gyrus, and the hippocampus, regions commonly associated with social cognition. Additionally, greater activity in these regions was associated with fewer total behavior problems. There was an indirect effect of early intervention on middle childhood psychosocial functioning mediated through increased activity in brain regions in response to maternal cues. CONCLUSIONS: These results suggest that early parenting intervention (in this case the ABC intervention) can enhance brain regions supporting children's social cognitive development. In addition, the findings highlight these brain effects as a possible neural pathway through which ABC may prevent future behavior problems among high-risk children, yielding psychosocial benefits that endure through at least middle childhood without the need to intervene with the child directly.

Changing institutional incentives to foster sound scientific practices: One department.

Replicable research and open science are of value to our field and to society at large, but most universities provide no incentives to adopt these practices. Instead, current incentive structures favor novel research, which has led to a situation in which few researchers take the time to do replications, share protocols, or share data. Obviously, several approaches to remedy this situation are possible. However, little progress can be made if becoming involved in such activities reduces a researcher's chances of rank and status advancement and other rewards. I describe in this article the way my department has modified our incentive structure to tackle this problem, including how the changes influence my research as a developmental psychologist. Finally, I offer suggestions for faculty who wish to initiate similar changes in their institutions.
