Parents share half of their genes with their children, but they also share background social factors and actively help shape their child’s environment – making it difficult to disentangle genetic and environmental causes of parent–offspring similarity. While adoption and extended twin family designs have been extremely useful for distinguishing genetic and nongenetic parental influences, these designs entail stringent assumptions about phenotypic similarity between relatives and require samples that are difficult to collect and therefore are typically small and not publicly shared. Here, we describe these traditional designs, as well as modern approaches that use large, publicly available genome-wide data sets to estimate parental effects. We focus in particular on an approach we recently developed, structural equation modeling (SEM)-polygenic score (PGS), that instantiates the logic of modern PGS-based methods within the flexible SEM framework used in traditional designs. Genetically informative designs such as SEM-PGS rely on different and, in some cases, less rigid assumptions than traditional approaches; thus, they allow researchers to capitalize on new data sources and answer questions that could not previously be investigated. We believe that SEM-PGS and similar approaches can lead to improved insight into how nature and nurture combine to create the incredible diversity underlying human behavior.
This study examined the independent and interactive effects of genetic risk for alcohol use disorder (AUD), parenting behaviors, and family environment on childhood impulsivity. Data were drawn from White (n = 5,991), Black/African American (n = 1,693), and Hispanic/Latino (n = 2,118) youth who completed the baseline assessment (age 9–10) and had genotypic data available from the Adolescent Brain Cognitive Development Study. Participants completed questionnaires and provided saliva or blood samples for genotyping. Results indicated no significant main effects of AUD genome-wide polygenic scores (AUD-PRS) on childhood impulsivity as measured by the UPPS-P scale across racial/ethnic groups. In general, parental monitoring and parental acceptance were associated with lower impulsivity; family conflict was associated with higher impulsivity. There was an interaction effect between AUD-PRS and family conflict, such that family conflict exacerbated the association between AUD-PRS and positive urgency, only among Black/African American youth. This was the only significant interaction effect detected from a total of 45 tests (five impulsivity dimensions, three subsamples, and three family factors), and thus may be a false positive and needs to be replicated. These findings highlight the important role of parenting behaviors and family conflict in relation to impulsivity among children.
Abnormal tau, a hallmark Alzheimer’s disease (AD) pathology, may appear in the locus coeruleus (LC) decades before AD symptom onset. Reports of subjective cognitive decline are also often present prior to formal diagnosis. Yet, the relationship between LC structural integrity and subjective cognitive decline has remained unexplored. Here, we aimed to explore these potential associations.
Methods:
We examined 381 community-dwelling men (mean age = 67.58; SD = 2.62) in the Vietnam Era Twin Study of Aging who underwent LC-sensitive magnetic resonance imaging and completed the Everyday Cognition scale to measure subjective cognitive decline along with their selected informants. Mixed models examined the associations between rostral-middle and caudal LC integrity and subjective cognitive decline after adjusting for depressive symptoms, physical morbidities, and family. Models also adjusted for current objective cognitive performance and objective cognitive decline to explore attenuation.
Results:
For participant ratings, lower rostral-middle LC contrast to noise ratio (LCCNR) was associated with significantly greater subjective decline in memory, executive function, and visuospatial abilities. For informant ratings, lower rostral-middle LCCNR was associated with significantly greater subjective decline in memory only. Associations remained after adjusting for current objective cognition and objective cognitive decline in respective domains.
Conclusions:
Lower rostral-middle LC integrity is associated with greater subjective cognitive decline. Although not explained by objective cognitive performance, such a relationship may explain increased AD risk in people with subjective cognitive decline as the LC is an important neural substrate important for higher order cognitive processing, attention, and arousal and one of the first sites of AD pathology.
There is no group of individuals more iconic of 1960s counterculture than the hippies – the long-haired, colorfully dressed youth who rebelled against mainstream societal values, preached and practiced love and peace, and generally sought more meaningful and authentic lives. These 'flower children' are now over sixty and comprise a significant part of the older population in the United States. While some hippies rejoined mainstream American society as they grew older, others still maintain the hippie ideology and lifestyle. This book is the first to explore the aging experience of older hippies by examining aspects related to identity, generativity, daily activities, spirituality, community, end-of-life care, and wellbeing. Based on 40 in-depth interviews with lifelong, returning, and past residents of The Farm, an intentional community in Tennessee that was founded in 1971 and still exists today, insights into the subculture of aging hippies and their keys to wellbeing are shared.
Intrinsically photosensitive retinal ganglion cells (ipRGCs) are the most recently discovered photoreceptor class in the human retina. This Element integrates new knowledge and perspectives from visual neuroscience, psychology, sleep science and architecture to discuss how melanopsin-mediated ipRGC functions can be measured and their circuits manipulated. It reveals contemporary and emerging lighting technologies as powerful tools to set mind, brain and behaviour.
Parent and family engagement in early education programs is associated with better developmental outcomes for children. This chapter reviews theory and research on family engagement in early childhood programs, including home visiting, with an eye towards how dual-generation programs and services are delivered to support healthy parenting and enhance child development. We emphasize how publicly-funded school readiness programs serving low-income families, such as Head Start, serve as a key context for reaching parents and families with services that support the development of their children. Evaluations of interventions embedded within Head Start have shown that programs supporting family engagement at home and in preschool have direct benefits for young children; however, longitudinal evidence of impacts is less robust. Taking what we know about family engagement to scale requires a careful consideration of what is known to facilitate such engagement, and what barriers exist to including parents of culturally and linguistically diverse children in these efforts. We conclude our chapter with an examinination of the implications of our findings for policy and practice such as the expansion of affordable early care and education programs, increasing access to culturally sensitive and inclusive parenting programs, and outreach to families via greater integration across early care and education programs, schools, community organizations, and medical/health settings that promote health and well-being of children and families both in the United States and internationally.
In this chapter we focus specifically on parenting from birth to age 5, a period marked by rapid development for the child and widely believed to set the foundation and quality of the emerging parent-child relationship. We begin with an overview of key developmental milestones, stages and transitions that influence the emergence and evolution of parenting over the period from birth to age 5. Then we review relations between five dimensions of parenting (sensitivity and parent child attachment, socialization, cognitive stimulation, discipline, and maltreatment) and relevant child outcomes, attending to child characteristics that moderate these associations. Next, we described parental characteristics and experiences that predict parenting behavior and child outcomes. These include: normative parental beliefs and emotions; acculturation processes and discrimination; childhood experiences; adult stress and trauma; and psychopathology. Throughout our review, we attend to the roles of race, ethnicity, and culture. This is followed by consideration of the value of this work for policy, prevention, and intervention efforts. In the summary, we draw attention to recent advances in this line of inquiry along with remaining limitations. We conclude by emphasizing our primary thesis: parenting in infancy and early childhood is a key factor that can enhance or undermine children’s concurrent and long-term wellbeing and achievement depending on the quality and context in which it occurs.
Empirical and theoretical advances and application to society are moved at different speed. Application work is frequently developed later because it requires the integration of knowledge from different research areas. In the present paper, we integrate literature coming from diverse areas of research in order to design a deductive reasoning intervention, based on the involved executive functions. Executive functions include working memory (WM)’s online executive processes and other off-line functions such as task revising and planning. Deductive reasoning is a sequential thinking process driven by reasoners’ meta-deductive knowledge and goals that requires the construction and manipulation of representations. We present a new theoretical view about the relationship between executive function and higher-level thinking, a critical analysis of the possibilities and limitations of cognitive training, and a metacognitive training procedure on executive functions to improve deductive reasoning. This procedure integrates direct instruction on deduction and meta-deductive concepts (consistency, necessity) and strategies (search for counterexamples and exhaustivity), together with the simultaneous training of WM and executive functions involved: Focus and switch attention, update WM representations, inhibit and revise intuitive responses, and control the emotional stress yielded by tasks. Likewise, it includes direct training of some complex WM tasks that demands people to carry out similar cognitive assignment than deduction. Our training program would be included in the school curriculum and attempts not only to improve deductive reasoning in experimental tasks, but also to increase students’ ability to uncover fallacies in discourse, to automatize some basic logical skills, and to be able to use logical intuitions.
Hoarding disorder is a surprisingly common problem which impacts on most areas of life. People who hoard typically have multiple agencies involved in their care due to the complex health and safety impact and risks associated with hoarding. ‘Treatment’ involves finding ways of supporting discarding large amounts, typically underpinned by CBT principles. We evaluated the impact and outcomes of a conference designed to boost professionals’ confidence and understanding in working with hoarding problems, both individually and with other agencies with a view to improving inter-agency service provision. Changes in professionals’ confidence and understanding were evaluated immediately before and after the conference. Conference participants’ qualitative responses related to service improvements were analysed using content analysis. People with personal experience of hoarding issues subsequently participated in a focus group where the results of the conference were presented. These data were analysed using thematic analysis. Confidence and understanding in working with hoarding problems substantially increased from pre- to post-conference. Professionals identified a range of possible improvements, most commonly working more closely and improving communication with other agencies. People with personal experience suggested improvements across three over-arching themes: developing an improved understanding of hoarding, the need for improved resources, and improved multi-agency working. A multi-agency conference increased confidence and understanding in professionals working with hoarding problems, and improvements specified by both people with personal experience and professionals provide a useful guide to service improvement. Results provide a framework in which CBT approaches should be embedded.
Key learning aims
(1) To assess the effectiveness of a multi-agency hoarding conference at improving understanding and confidence in working with hoarding problems.
(2) To explore professionals’ perceptions of improvements to multi-agency service provision.
(3) To explore perceptions of improvements that could be made to multi-agency service provision from people with personal experience of hoarding problems.
Human infants are born needing their caregivers’ support to accomplish challenges related to both security and exploration. Accordingly, the quality of care infants receive influences their ability to appraise the degree of threat inherent to any challenge, signal needs for assistance, and regulate their responses. In this manner, parenting affects whether young children manage challenges with behavior or physiological responses. The extent to which stress physiology is repeatedly invoked in response to challenges, alongside variation in neural growth accompanying children’s exploratory behavior, in turn affects neurodevelopment and ultimately functioning with age. We discuss the processes through which this occurs, the potential impact on attachment schemas, and implications for intervention programs designed at improving parenting and well-being.
The field of mental health is experiencing a trend toward the implementation of early intervention using empirically validated parent-training programs. These programs serve to promote the social-emotional development, communication skills, and school readiness of children. Unfortunately, access to services to improve parenting behaviors is severely limited for many families, especially low-income families who live in rural areas. Through the use of recent advances in multimedia technology and the ubiquity of mobile/computer networking via the Internet, there now exists an opportunity to provide interventions to families distally. As well, the COVID-19 pandemic has forced people to use technology in order maintain safety. In response, remote-access interactive parenting interventions are emerging. Interactive Internet/mobile Computer Mediated Interventions (IICMI) in the home overcome common obstacles for parent participation, such as lack of transportation, harsh weather, long distances or schedule conflicts and have the capacity to provide menus of choices efficiently, tailor information to subject characteristics and interests, manage interactive programming, and provide support to professionals and peers. Yet, the digital divide mirrors health disparities and the process of getting accurate, best-practice information is harder rather than easier. This chapters seeks to address the issues associated with remote delivery of parent-training programs.
This chapter provides an overview of parents’ discipline and punishment in relation to child development. Main types of discipline (e.g., inductive reasoning, love withdrawal, power assertion) are described, and child- (e.g., behavior problems), parent- (e.g., stress), and community- (e.g., norms) level predictors of discipline are considered. The chapter then describes moderators (child gender, child age, temperament, overall climate of the parent-child relationship, and culture) and mediators (children’s perceptions of parental love and affection, social information processing, development of empathy and conscience, neurocognition) of associations between discipline and child outcomes. Next, implications of research on discipline for practice and policy are discussed in terms of the international agenda set by the Sustainable Development Goals, national bans on corporal punishment, and parenting interventions focused on discipline. The chapter concludes by examining limitations of the current research and suggesting directions for future research.
Parent-child relationships are extremely important for sexual and gender minoritized youth as they and their families navigate the challenges of “coming out” and living in a highly heteronormative and often homonegative and transnegative society. This chapter presents the current terminology for and demography of LGBTQ youth in the United States; discusses the unique experiences of LGBTQ children and their parents, including child and parent reactions to the coming out process and its reverberations through the family system; reviews the emerging scientific literature on parenting effects on LGBTQ child health and well-being; and considers the implications for policy and clinical practice that support parents of LGBTQ youth in ways that foster nurturance, advocacy, and the health and well-being of both youth and parents.
