A new framework for understanding stress and disease: the developmental model of stress as applied to multiple sclerosis.

This paper proposes a new model of stress that integrates earlier models and adds insights from developmental psychology. Previous models describe the behavioral and physical effects of stress events, but have not explained the translation of experiences into stress itself. The Developmental Model of Stress shows how psychosocial developmental challenges in childhood create persistent negative beliefs and behaviors that increase threat perception and maladaptive stress responses. These developmental challenges produce early psychological and physiological predispositions for increased stress responses over time. Ongoing stress leads to dysregulation of physical stress-response systems (allostatic load), which is associated with multiple diseases. High allostatic load provides the necessary preconditions for the diathesis-stress model, which says the addition of an acute stressor to a weakened or predisposed system can lead to disease development. The paper also documents the evolving measurement of stress to better understand the stress-disease relationship, helping to resolve conflicting results between studies. The Developmental Model of Stress was combined with clinician insight and patient reports to build an integrative framework for understanding the role of stress in the development and progression of multiple sclerosis (MS). It includes the first mapping of maladaptive beliefs and behaviors arising from developmental challenges that are common to people with MS. An initial comparison shows these may be distinct from those of people with other chronic diseases. These beliefs and behaviors form the predisposing factors and contribute to the triggering factors, which are the acute stressors triggering disease onset. These often took two forms, a prolonged incident experienced as feeling trapped or stuck, and threat of a breach in a relationship. The reinforcing factors add the stress of a chronic disease with a poor prognosis and seemingly random symptom fluctuation, still managed with the same beliefs and behaviors developed in childhood, increasing physiological dysregulation and symptom severity. A pilot study is described in which these three categories of stress factors in MS were explicitly addressed. This study noted clinically important improvements in physical and mental well-being, providing preliminary support for the Developmental Model. Future research might expand on the pilot using a more robust sample and design.

Parents perception and experience of transitioning to adulthood for their child diagnosed with an intellectual disability.

Definitions of adulthood for people with intellectual disability are often complicated, with milestones being markedly different for this population. This is then associated with difficulties for both the people with intellectual disability and their parents, who are closely involved in this transitional period. This paper aims to report on parents' perception and experience of adulthood for their son or daughter with an Intellectual Disability (ID). Qualitative data were collected through 30 - 60-minute phone interviews with eight parents of a person with an intellectual disability aged 15 or older (mean parent age = 60; mean child age = 23). Thematic analysis found that Perception of Adulthood encompassed themes of Independence and Normality. Experiences of Adulthood were categorised under Government Services, Responsibility and Social Supports. Findings of this research provide information for the growing literature around adulthood for people with intellectual disability, as well as how to amend policies and procedures for services that cater to people with intellectual disability and their parents during this transition.

Übersichtsarbeiten / Review Articles. Die Entwicklung von epistemischerWachsamkeit und epistemischem Vertrauen über die Lebensspanne: Perspektive aus der empirischen Forschung zum selbstregulierenden sozialen Lernen / The Development of Epistemic Vigilance and Epistemic Trust Across the Lifespan: Perspectives from Empirical Research on Self-Regulatory Social Learning.

The Development of Epistemic Vigilance and Epistemic Trust Across the Lifespan: Perspectives from Empirical Research on Self-Regulatory Social Learning This article examines what we know about the development of epistemic vigilance and epistemic trust between early infancy and adolescence.With this brief review, we intend to help put into perspective the hypotheses advanced by Fonagy and his colleagues within the socio-epistemic theory of psychopathology, according to which psychopathology reflects a closure to interpersonal communication resulting from unfavorable learning experiences in early development. Here, we will discuss how children become sensitive to overt interpersonal communication, and what cognitive skills underpin such sensitivity. Next, we shall discuss the empirical evidence that children in the second year of life already possess a rudimentary capacity for epistemic vigilance: they seem to evaluate the competence of different adult informants and appear to seek information and learn from adults based on such evaluations. Third, we will outline studies showing that in the third year of life children appear to increasingly trust ostensive communication, up to the point of becoming (at least apparently) less sensitive to the possibility of being misinformed or deceived. Finally, we will discuss how, between late childhood and adolescence, children first learn to distinguish lies, then irony, and increasingly engage in complex communication ecologies. Our review simultaneously supports the basic principles of the socio-epistemic theory of psychopathology and suggests that the theory needs further refinement of its ontogenetic predictions.

Incorporating simulated spatial context information improves the effectiveness of contrastive learning models.

Visual learning often occurs in a specific context, where an agent acquires skills through exploration and tracking of its location in a consistent environment. The historical spatial context of the agent provides a similarity signal for self-supervised contrastive learning. We present a unique approach, termed environmental spatial similarity (ESS), that complements existing contrastive learning methods. Using images from simulated, photorealistic environments as an experimental setting, we demonstrate that ESS outperforms traditional instance discrimination approaches. Moreover, sampling additional data from the same environment substantially improves accuracy and provides new augmentations. ESS allows remarkable proficiency in room classification and spatial prediction tasks, especially in unfamiliar environments. This learning paradigm has the potential to enable rapid visual learning in agents operating in new environments with unique visual characteristics. Potentially transformative applications span from robotics to space exploration. Our proof of concept demonstrates improved efficiency over methods that rely on extensive, disconnected datasets.

Considering the associations of adverse and positive childhood experiences with health behaviors and outcomes among emerging adults.

Childhood is a sensitive period of development during which early life experiences can facilitate either positive or negative health trajectories across subsequent developmental periods. Previous research has established strong links between adverse childhood experiences (ACEs) and adverse health outcomes (e.g., sleep-related problems, pain, substance use). Despite this, less is known about positive childhood experiences (PCEs) and how they may buffer the effects of ACEs on health outcomes. The current study investigated whether PCEs moderate the associations between ACEs and health behavior and health-related outcomes (i.e., cannabis use, alcohol use, sleep disturbance, sleep-related impairment, pain intensity, and pain interference) in a sample of at-risk emerging adults. Participants (N = 165) were undergraduate college students (18-25 years of age) who reported frequent alcohol and/or cannabis use (≥3 times in the past week). A significant positive association was found between ACEs and cannabis use. There were also significant negative associations found between PCEs and pain interference and intensity. PCEs did not moderate any of the associations between ACEs and health behavior and health-related outcomes (i.e., cannabis use, alcohol use, sleep disturbance, sleep-related impairment, pain intensity, and pain interference). Findings suggest that PCEs may be unlikely to serve as a strong enough protective factor during early life to decrease risk for suboptimal health and health behaviors during emerging adulthood among individuals who report a greater accumulation of ACEs. Longitudinal research is needed to identify additional related risk and protective factors during early life to further support health and health behavior during this transitional period of development and beyond.

Healing wounded trees: clinicians' perspectives on treatment of complex posttraumatic stress disorder.

While treatment guidelines agree on the first-line interventions for the treatment of posttraumatic stress disorder (PTSD), there is an ongoing debate between experts regarding the treatment of complex posttraumatic stress disorder (C-PTSD). As scientific research is slowly emerging, different treatment approaches are used in clinical practice This article aims to provide a set of treatment options for C-PTSD in adult survivors of repeated exposure to severe violence and abuse, both in childhood and later on in life. The developmental-contextual perspective on mental health forms the basis of this approach. This perspective is elaborated using the tree metaphor. Then, several treatment strategies are suggested. The presented strategies are a combination of the existing evidence-based approaches for the treatment of PTSD and personality disorders. They target psychological damage in survivors while taking their developmental trajectories and ecological environments into consideration. The treatment model presented is based on longstanding clinical practice and it may be a promising framework for treating C-PTSD. However, it still needs to be scientifically examined for acceptability and effectiveness.

The Power of Play: Examining the Impact of a School Yard Playground on Attitudes Toward School and Peer Relationships Among Elementary School Students in Chennai, India.

Introduction. School environments may impact elementary school students' attachment levels to school as well as their mental and emotional well-being. Yet investments in recess/play infrastructure lag commitments to academic resources, particularly in developing countries. The main objective was to examine the impact of installing playground equipment, in the school yard, on students' attitudes toward school, peers, and the capacity to play of elementary-school children in an underserved, inner-city school in Chennai, India. Methods. A previously validated school attachment questionnaire was modified and administered to 140 and 148 students in pre- and post-playground installation, respectively. Results. For 7 out of 13 survey questions, student attitudes about their own recreational time and their attitudes toward peers significantly improved after playground installation. Conclusion. These results highlight the need for investments in play spaces, and recreational equipment may be just as important as addressing academic needs, especially among underserved children.

ESDM intervention in severe preschool autism: an Italian Case report, psychological and social medicine reflections.

BACKGROUND: The goal of our contribution is to discuss a preschool intervention based on the Early Start Denver Model and the use of the main tools for the detection of adaptive behaviour in cases of autism: Vineland, ABAS. CASE PRESENTATION: the work is the presentation of a clinical case that has benefited from an intervention with the Early Start Denver Model methodology for the benefit of a child with socio-cultural and economic disadvantages. This early intervention, in a child of 36 months, which followed the diagnosis, was possible thanks to the intervention of many third-sector organizations which allowed this child, with a serious autism profile, to receive an evidence-based intervention for free. At the beginning of the intervention, the child presented a diagnosis of severe autism with absence of gaze, vocalizations and other communicative impairments. The level of motor clumsiness was also quite high, as were stereotypies. CONCLUSIONS: Research has shown the usefulness of intervening in this area with an early assessment and/or diagnosis and immediate intervention; however, public health services are not always able to maintain this pace. Our contribution therefore shows on the one hand the evidence of the improvements achieved by the child despite the low intensity of the treatment, and on the other hand, demonstrates the total versatility and adaptability of the Denver Model to the Italian context. In our conclusions, there are also some reflections on the tools used to measure adaptive behavior which seem to have a number of limitations and criticalities.

The impact of parenting practices and family economy on psychological wellbeing and learning patterns in higher education students.

BACKGROUND: There is a large literature on the significant impact of rearing factors in the psychological development of different child's learning patterns and wellbeing in elementary and secondary schools, but there is a scarcity of studies on to what extent those influences remain stable up to higher education. OBJECTIVE: In this study, parenting practices and family status were analyzed as predictors of the different learning styles, psychological difficulties, mental health factors, and academic performance, comprising the psychosocial diversity in learning (DinL) at the university classroom. METHODS: Using a cross-sectional design, a questionnaire was administered to a sample of 2522 students at the Complutense University of Madrid (Spain). It included a DinL scale measuring five psychological learning dimensions (coping with difficulties, effort, autonomy, Social/Physical Context, and understanding/career interest), plus several items on retrospective parenting practices, family, and sociodemographic variables. Multiple regressions and analyses of variance were conducted with the family factors as independent variables and the learning factors as dependent variables. RESULTS: Results showed parenting variables, parents' education, and family economy as having a significant impact on psychological learning dimensions, academic performance, and especially on the students' wellbeing and mental health status, being an important contributors to explain the DinL in the university classroom. CONCLUSION: The results bring interesting conclusions for developmental and health psychologists when working with parents aimed at fostering wellbeing and learning strategies related to academic inclusion and achievement.

Cultural traits operating in senders are driving forces of cultural evolution.

We introduce a mathematical model of cultural evolution to study cultural traits that shape how individuals exchange information. Current theory focuses on traits that influence the reception of information (receiver traits), such as evaluating whether information represents the majority or stems from a trusted source. Our model shifts the focus from the receiver to the sender of cultural information and emphasizes the role of sender traits, such as communicability or persuasiveness. Here, we show that sender traits are probably a stronger driving force in cultural evolution than receiver traits. While receiver traits evolve to curb cultural transmission, sender traits can amplify it and fuel the self-organization of systems of mutually supporting cultural traits, including traits that cannot be maintained on their own. Such systems can reach arbitrary complexity, potentially explaining uniquely human practical and mental skills, goals, knowledge and creativity, independent of innate factors. Our model incorporates social and individual learning throughout the lifespan, thus connecting cultural evolutionary theory with developmental psychology. This approach provides fresh insights into the trait-individual duality, that is, how cultural transmission of single traits is influenced by individuals, who are each represented as an acquired system of cultural traits.

Biomarker adoption in developmental science: A data-driven modelling of trends from 90 biomarkers across 20 years.

Developmental scientists have adopted numerous biomarkers in their research to better understand the biological underpinnings of development, environmental exposures, and variation in long-term health. Yet, adoption patterns merit investigation given the substantial resources used to collect, analyse, and train to use biomarkers in research with infants and children. We document trends in use of 90 biomarkers between 2000 and 2020 from approximately 430,000 publications indexed by the Web of Science. We provide a tool for researchers to examine each of these biomarkers individually using a data-driven approach to estimate the biomarker growth trajectory based on yearly publication number, publication growth rate, number of author affiliations, National Institutes of Health dedicated funding resources, journal impact factor, and years since the first publication. Results indicate that most biomarkers fit a "learning curve" trajectory (i.e., experience rapid growth followed by a plateau), though a small subset decline in use over time.

Are Genetic and Environmental Risk Factors for Psychopathology Amplified in Children with Below-Average Intelligence? A Population-Based Twin Study.

There is a negative association between intelligence and psychopathology. We analyzed data on intelligence and psychopathology to assess this association in seven-year-old Dutch twin pairs (ranging from 616 to 14,150 depending on the phenotype) and estimated the degree to which genetic and environmental factors common to intelligence and psychopathology explain the association. Secondly, we examined whether genetic and environmental effects on psychopathology are moderated by intelligence. We found that intelligence, as assessed by psychometric IQ tests, correlated negatively with childhood psychopathology, as assessed by the DSM-oriented scales of the Child Behavior Check List (CBCL). The correlations ranged between - .09 and - .15 and were mainly explained by common genetic factors. Intelligence moderated genetic and environmental effects on anxiety and negative affect, but not those on ADHD, ODD, and autism. The heritability of anxiety and negative affect was greatest in individuals with below-average intelligence. We discuss mechanisms through which this effect could arise, and we end with some recommendations for future research.

Child development, film evidence, and epidemiological sciences: Elwyn James Anthony and the 1957 Zurich International Congress of Psychiatry.

In 1957, the British-Indian child psychiatrist Dr Elwyn James Anthony travelled to the Zurich International Congress of Psychiatry to show a film featuring 70 children with such complex symptomatology and behaviour that they betrayed the certainty of contemporary theories of developmental psychology and psychoanalysis. This article examines the significance of Anthony's film to the creation of new scientific models in international developmental psychology and psychiatric epidemiology. It marked a significant change in the use of filmed evidence that sought to create a truly global and universalist approach to atypical child development based purely on scientific observations. This new observational work was important in shaping new internationally ratified models to study the epidemiology of children's psychiatric conditions.

Work engagement among older workers: a systematic review.

OBJECTIVES: Given current labor force conditions, including population aging, keeping older workers engaged in work and motivated is important. Aging may alter the effects that psychological and environmental factors have on work engagement. We conducted a systematic review to understand the features of work engagement among older workers. METHODS: A systematic search was conducted in July 2022 using 4 databases. The review included relevant articles that focused on participants aged 40 years and older. RESULTS: Fifty articles were selected for our review, which were grouped into 5 categories: (1) studies examining the relationship between chronological age and work engagement, (2) studies investigating the moderating effects of age on the relationship between job-related psychological factors and work environment factors and work engagement, (3) studies comparing the relationship of job-related psychological factors and work environment factors with work engagement across different age groups, (4) studies exploring the relationship between work engagement and retirement intentions or continued employment beyond retirement age, and (5) other studies discussing work engagement in the context of older workers. Most articles focused on workers in Europe and the United States and used observational study designs. CONCLUSIONS: Work engagement increases with age, and is mainly mediated by increased emotional regulation. In addition, age moderates the relationships between various job-related psychological and work-environmental factors and work engagement. Work engagement is associated with working beyond retirement age. Organizations should understand the characteristics of work engagement among older workers and make age-conscious efforts to support them in adapting to social changes.

A transdisciplinary view on curiosity beyond linguistic humans: animals, infants, and artificial intelligence.

Curiosity is a core driver for life-long learning, problem-solving and decision-making. In a broad sense, curiosity is defined as the intrinsically motivated acquisition of novel information. Despite a decades-long history of curiosity research and the earliest human theories arising from studies of laboratory rodents, curiosity has mainly been considered in two camps: 'linguistic human' and 'other'. This is despite psychology being heritable, and there are many continuities in cognitive capacities across the animal kingdom. Boundary-pushing cross-disciplinary debates on curiosity are lacking, and the relative exclusion of pre-linguistic infants and non-human animals has led to a scientific impasse which more broadly impedes the development of artificially intelligent systems modelled on curiosity in natural agents. In this review, we synthesize literature across multiple disciplines that have studied curiosity in non-verbal systems. By highlighting how similar findings have been produced across the separate disciplines of animal behaviour, developmental psychology, neuroscience, and computational cognition, we discuss how this can be used to advance our understanding of curiosity. We propose, for the first time, how features of curiosity could be quantified and therefore studied more operationally across systems: across different species, developmental stages, and natural or artificial agents.

Maximizing valid eye-tracking data in human and macaque infants by optimizing calibration and adjusting areas of interest.

Remote eye tracking with automated corneal reflection provides insights into the emergence and development of cognitive, social, and emotional functions in human infants and non-human primates. However, because most eye-tracking systems were designed for use in human adults, the accuracy of eye-tracking data collected in other populations is unclear, as are potential approaches to minimize measurement error. For instance, data quality may differ across species or ages, which are necessary considerations for comparative and developmental studies. Here we examined how the calibration method and adjustments to areas of interest (AOIs) of the Tobii TX300 changed the mapping of fixations to AOIs in a cross-species longitudinal study. We tested humans (N = 119) at 2, 4, 6, 8, and 14 months of age and macaques (Macaca mulatta; N = 21) at 2 weeks, 3 weeks, and 6 months of age. In all groups, we found improvement in the proportion of AOI hits detected as the number of successful calibration points increased, suggesting calibration approaches with more points may be advantageous. Spatially enlarging and temporally prolonging AOIs increased the number of fixation-AOI mappings, suggesting improvements in capturing infants' gaze behaviors; however, these benefits varied across age groups and species, suggesting different parameters may be ideal, depending on the population studied. In sum, to maximize usable sessions and minimize measurement error, eye-tracking data collection and extraction approaches may need adjustments for the age groups and species studied. Doing so may make it easier to standardize and replicate eye-tracking research findings.

Beyond empathy: Cognitive capabilities increase or curb altruism in middle childhood.

Altruistic behavior, which intentionally benefits a recipient without expectation of a reward or at a cost to the actor, is observed throughout the lifespan from everyday interactions to emergency situations. Empathy has long been considered a major driver of altruistic action, but the social information processing model supports the idea that other cognitive processes may also play a role in altruistic intention and behavior. Our aim was to investigate how visual analysis, attention, inhibitory control, and theory of mind capabilities uniquely contribute to predicting altruistic intention and behavior in a sample of 67 French children (35 girls and 32 boys; Mage = 9.92 ± 0.99 years) from Paris and neighboring suburbs. Using a Bayesian analysis framework, we showed that in younger grade levels visual analysis and selective attention are strong predictors of altruistic intention and that inhibitory control strongly predicts altruistic behavior in a dictator game. Processes underlying theory of mind, however, negatively predict altruistic behavior in the youngest grade. In higher grade levels, we found that stronger attention and inhibitory control predicts lower altruistic intention and behavior. Empathy was not found to predict altruistic intention or behavior. These results suggest that different cognitive capabilities are involved in altruistic intention and behavior and that their contribution changes throughout middle childhood as social constraints deepen and altruism calls on more complex reasoning.

Preschoolers search longer when there is more information to be gained.

What drives children to explore and learn when external rewards are uncertain or absent? Across three studies, we tested whether information gain itself acts as an internal reward and suffices to motivate children's actions. We measured 24-56-month-olds' persistence in a game where they had to search for an object (animal or toy), which they never find, hidden behind a series of doors, manipulating the degree of uncertainty about which specific object was hidden. We found that children were more persistent in their search when there was higher uncertainty, and therefore, more information to be gained with each action, highlighting the importance of research on artificial intelligence to invest in curiosity-driven algorithms.

Parents-children co-regulation as therapeutic variable and target in autism spectrum disorders. From observation of drive to need of cooperative parent-mediated therapy.

Abstract: Autism spectrum disorders (ASDs) belong to the category of neurodevelopmental disorders. ASD emerges in early childhood and involves deficits in communication, language, behavioural inflexibility and fixity, and sensorial neurodivergent perception. ASDs have a biological pathogenesis related to genetic and epigenetic factors. Additionally, research has shown that starting from childhood, autistic persons could find emotional regulation challenging during communication with caregivers. The importance of emotional co-regulation has always been under-lined in psychology, starting with Freud who introduced the concept of the Compassionate Other. Emotional difficulties are grasped immediately and almost instinctively by parents, who try to modulate their approach to the child's needs from the very beginning. This paper seeks to highlight the importance of emotional co-regulation as a wake-up call-in developmental trajectories that present peculiarities or anomalies. It also emphasizes the significance of emotional co-regulation as a useful tool for intervening in the dysfun-ctionality of such trajectories. This intervention aims to directly involve parents in treatment, as seen in Cooperative parent-mediated therapy. This approach is crucial for facilitating the evolution of the cognitive framework while utilizing this target. This article aims to review the most recent literature on co-regulation after explaining the theoretical framework that gave rise to this concept. It's now well established the importance of adopting a develop-mental approach that starts from the bodily dimension as the basis for the relationship with caregivers, pairs, and unfamiliar people. It is from this basis that starts the affective, emotional, and cognitive construction of the internal and external world of the child. This scoping review takes into account the most recent evidence on co-regulation and autism, emphasizing the importance of this process in diagnostic and therapeutic settings.
