An Executive Functioning Perspective In Neurofibromatosis Type 1: From Adhd And Autism Spectrum Disorder To Research Domains, Taylor Smith, Jessica A. Kaczorokski, Maria T. Acosta

Psychology and Child Development

Purpose: Neurofibromatosis type 1 (NF1) is a rare monogenic disorder associated with executive function (EF) deficits and heightened risk for attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). The goal of this paper is to understand how EFs provide a common foundation to understand vulnerabilities for ADHD and ASD within NF1.

Methods: A literature review and synthesis was conducted.

Results: EF difficulties in working memory, inhibitory control, cognitive flexibility, and planning are evident in NF1, ADHD, and ASD. However, relatively little is known about the heterogeneity of EFs and ADHD and ASD outcomes in NF1. Assessment of ADHD and ASD …

Neurofibromatosis Type 1 Implicates Ras Pathways In The Genetic Architecture Of Neurodevelopmental Disorders, Jessica A. Kaczorowski, Taylor Smith, Amanda M. Shrewsbury, Leah R. Thomas, Valerie S. Knopik, Maria T. Acosta

Psychology and Child Development

The genetic architecture of neurodevelopmental disorders is largely polygenic, non-specific, and pleiotropic. This complex genetic architecture makes the search for specific etiological mechanisms that contribute to neurodevelopmental risk more challenging. Monogenic disorders provide an opportunity to focus in on how well-articulated signaling pathways contribute to risk for neurodevelopmental outcomes. This paper will focus on neurofbromatosis type 1 (NF1), a rare monogenic disorder that is associated with varied neurodevelopmental outcomes. Specifically, this paper will provide a brief overview of NF1 and its phenotypic associations with autism spectrum disorder, attention-deficit/hyperactivity disorder, and specific learning disorders, describe how variation within the NF1 gene …

The Psychology Of Sexual Harassment, Shawn Meghan Burn

Psychology and Child Development

Sexual harassment (SH) occurs when people are targets of unwanted sexual comments, sexual gestures, or sexual actions because of their actual or perceived gender, gender expression, or sexual orientation. Due to its frequency and harmful effects on people and organizations, and because it is often a symptom of social inequalities, SH is of concern to psychologists. Using psychological theory and research as well as intersectional and contextual lenses, this article describes how SH is varied in its forms, targets, and origins. I explore explanations for SH with a focus on sociocultural gender and power perspectives. I also employ a person-by-situation …

Appeal To Bystander Interventions: A Normative Approach To Health And Risk Messaging, Shawn M. Burn

Psychology and Child Development

Bystander intervention is a form of helping that occurs when onlookers intercede to provide direct or indirect aid to a victim. When bystanders step in to prevent or reduce harm to others, they act as agents of primary and secondary health prevention. But theory and research suggest the bystander intervention process is complex and multiple social-psychological and situational barriers imperil bystander action. Bystanders are often ill-prepared to intervene when others are at risk for emotional or physical harm. They may not notice that someone needs help due to distraction from self-focus, engagement in social interaction, intoxication, or aspects of the …

The Prenatal Environment In Twin Studies: A Review On Chorionicity, Kristine Marceau, Minni T.B. Mcmaster, Taylor F. Smith, Joost G. Daams, Catharina E.M. Van Beijsterveldt, Dorret I. Boomsma, Valerie S. Knopik

Psychology and Child Development

A literature search was conducted to identify articles examining the association of chorionicity (e.g., whether twins share a single chorion and thus placenta or have separate chorions/placentas) and genetics, psychiatry/behavior, and neurological manifestations in humans twins and higher-order multiples. The main aim was to assess how frequently chorionicity has been examined in relation to heritability estimates, and to assess which phenotypes may be most sensitive to, or affected by, bias in heritability estimates because of chorionicity. Consistent with the theory that some chorionicity effects could lead to overestimation and others to underestimation of heritability, there were instances of each across …

Pre- And Perinatal Ischemia-Hypoxia, The Ischemia-Hypoxia Response Pathway, And Adhd Risk, Taylor F. Smith, Rainald Schmidt-Kastner, John E. Mcgeary, Jessica A. Kaczorowski, Valerie S. Knopik

Psychology and Child Development

This review focuses on how measured pre- and perinatal environmental and (epi)genetic risk factors are interrelated and potentially influence one, of many, common developmental pathway towards ADHD. Consistent with the Developmental Origins of Health and Disease hypothesis, lower birth weight is associated with increased ADHD risk. Prenatal ischemia-hypoxia (insufficient blood and oxygen supply in utero) is a primary pathway to lower birth weight and produces neurodevelopmental risk for ADHD. To promote tissue survival in the context of ischemia-hypoxia, ischemia-hypoxia response (IHR) pathway gene expression is altered in the developing brain and peripheral tissues. Although altered IHR gene expression is adaptive …

Passive RGe Or Developmental Gene-Environment Cascade? An Investigation Of The Role Of Xenobiotic Metabolism Genes In The Association Between Smoke Exposure During Pregnancy And Child Birth Weight, Kristine Marceau, Rohan H.C. Palmer, Jenae M. Neiderhiser, Taylor F. Smith, John E. Mcgeary, Valerie S. Knopik

Psychology and Child Development

There is considerable evidence that smoke exposure during pregnancy (SDP) environmentally influences birth weight after controlling for genetic influences and maternal characteristics. However, maternal smoking during pregnancy—the behavior that leads to smoke exposure during pregnancy—is also genetically-influenced, indicating the potential role of passive gene-environment correlation. An alternative to passive gene-SDP correlation is a cascading effect whereby maternal and child genetic influences are causally linked to prenatal exposures, which then have an ‘environmental’ effect on the development of the child’s biology and behavior. We describe and demonstrate a conceptual framework for disentangling passive rGE from this cascading GE effect using …

Maternal Smoking During Pregnancy And Offspring Birth Weight: A Genetically-Informed Approach Comparing Multiple Raters, Valerie S. Knopik, Kristine Marceau, Rohan H.C. Palmer, Taylor F. Smith, Andrew C. Heath

Psychology and Child Development

Maternal smoking during pregnancy (SDP) is a significant public health concern with adverse consequences to the health and well-being of the fetus. There is considerable debate about the best method of assessing SDP, including birth/medical records, timeline follow-back approaches, multiple reporters, and biological verification (e.g., cotinine). This is particularly salient for genetically-informed approaches where it is not always possible or practical to do a prospective study starting during the prenatal period when concurrent biological specimen samples can be collected with ease. In a sample of families (N = 173) specifically selected for sibling pairs discordant for prenatal smoking exposure, we: …

Angiogenic, Neurotrophic, And Inflammatory System Snps Moderate The Association Between Birth Weight And Adhd Symptom Severity, Taylor F. Smith, Arthur D. Anastopoulos, Melanie E. Garrett, Alejandro Arias-Vasquez, Barbara Franke, Robert D. Oades, Edmund Sonuga-Barke, Philip Asherson, Michael Gill, Jan K. Buitelaar, Joseph A. Sergeant, Scott H. Kollins, Stephen V. Faraone, Allison Ashley-Koch, Image Consortium

Psychology and Child Development

Low birth weight is associated with increased risk for Attention-Deficit/Hyperactivity Disorder (ADHD); however, the etiological underpinnings of this relationship remain unclear. This study investigated if genetic variants in angiogenic, dopaminergic, neurotrophic, kynurenine, and cytokine-related biological pathways moderate the relationship between birth weight and ADHD symptom severity. A total of 398 youth from two multi-site, family-based studies of ADHD were included in the analysis. The sample consisted of 360 ADHD probands, 21 affected siblings, and 17 unaffected siblings. A set of 164 SNPs from 31 candidate genes, representing five biological pathways, were included in our analyses. Birth weight and gestational age …

Discrepant Visual Speech Faciliates Covert Selective Listening In "Cocktail Party" Conditions, Jason A. Williams

Psychology and Child Development

The presence of congruent visual speech information facilitates the identification of auditory speech, while the addition of incongruent visual speech information often impairs accuracy. This latter arrangement occurs naturally when one is being directly addressed in conversation but listens to a different speaker. Under these conditions, performance may diminish since: (a) one is bereft of the facilitative effects of the corresponding lip motion and (b) one becomes subject to visual distortion by incongruent visual speech; by contrast, speech intelligibility may be improved due to (c) bimodal localization of the central unattended stimulus. Participants were exposed to centrally presented visual and …

Gender, Ethnic Identity, And Environmental Concern In Asian Americans And European Americans, Shawn M. Burn, Patricia L. Winter, Brittany Hori, N. Clayton Silver

Psychology and Child Development

There are relatively few articles in sociology and psychology on gender; ethnicity, and the environment, yet ethnic and gender neutral approaches to sustainability may be incomplete. We studied gender, ethnicity and environmental concern ·with an internet sample of Asian American women (n=157) and men (n=69), and European American women (n=222) and men (n=99). Participants completed the New Ecological Paradigm measure (NEP; Dunlap et al., 2000), the value bases of environmental concern (Schultz, 2000), and the Multigroup Ethnic Identity Measure-Revised (MEIMR; Phinney & Ong, 2007). A 2 ( ethnicity) x 2 (gender) ANOVA found no gender or ethnic differences on the …

Strategies For Reducing Inequalities And Improving Developmental Outcomes For Young Children In Low-Income And Middle-Income Countries, Patrice L. Engle, Lia C.H. Fernald, Harold Alderman, Jere Behrman, Chloe O'Gara, Aisha Yousafzai, Meena Cabral De Mello, Melissa Hidrobo, Nurper Ulkuer, Ilgi Ertem, Selim Iltus

Psychology and Child Development

This report is the second in a Series on early child development in low-income and middle-income countries and assesses the effectiveness of early child development interventions, such as parenting support and preschool enrollment. The evidence reviewed suggests that early child development can be improved through these interventions, with effects greater for programmes of higher quality and for the most vulnerable children. Other promising interventions for the promotion of early child development include children’s educational media, interventions with children at high risk, and combining the promotion of early child development with conditional cash transfer programmes. Effective investments in early child development …

Self-Regulation Of Emotion, Functional Impairment, And Comorbidity Among Children With Ad/Hd, Arthur D. Anastopoulos, Taylor Smith, Melanie E. Garrett, Erin Morrissey-Kane, Nicole K. Schatz, Jennifer L. Sommer, Scott H. Kollins, Allison Ashley-Koch

Psychology and Child Development

Objective: This study investigated the role of self-regulation of emotion in relation to functional impairment and comorbidity among children with and without AD/HD. Method: A total of 358 probands and their siblings participated in the study, with 74% of the sample participants affected by AD/HD. Parent-rated levels of emotional lability served as a marker for self-regulation of emotion. Results: Nearly half of the children affected by AD/HD displayed significantly elevated levels of emotional lability versus 15% of those without this disorder. Children with AD/HD also displayed significantly higher rates of functional impairment, comorbidity, and treatment service utilization. …

Adapting Clinical Services To Accommodate Needs Of Refugee Populations, Jessica A. Kaczorowski, Ann Shah Williams, Taylor F. Smith, Niloofar Fallah, Julia L. Mendez, Rosemery Nelson-Gray

Psychology and Child Development

The diversity of the refugee population in the United States requires practicing psychologists to respond by adapting clinical services to meet their mental health needs. However, the available literature on culturally adapted treatments is only a first step in guiding the process for adapting clinical services. This paper describes our experiences with designing and adapting a variety of clinical services for youth and families with refugee status. Guided by Sue's (2006) tenets for culturally competent service delivery, we discuss a therapeutic model of tiered service delivery used to deliver preventative services and treatment to refugee youth and adults. We discuss …

Meta-Analysis Of The Heterogeneity In Association Of Drd4 7-Repeat Allele And Ad/Hd: Stronger Association With Ad/Hd Combined Type, Taylor F. Smith

Psychology and Child Development

The purpose of this meta-analysis was to examine whether association studies between attention deficit/hyperactivity disorder (AD/HD) and the dopamine receptor 4 gene 7-repeat (DRD4 7R) allele vary systematically based on study characteristics. A total of 27 empirical studies with 28 distinct samples using either case–control or family-based association analyses were included. Consistent with previous meta-analytic work [Gizer et al. (2009), Hum Genet 126:51–90], the DRD4 7R allele was associated with AD/HD across studies (OR = 1.33; 95% CI = 1.16–1.53, z = 4.04, P = 0.00005) and there was significant systematic variability among studies (Q = 54.24; P = …

Effects Of Reticence, Affect For Communication Channels, And Self-Perceived Competence On Usage Of Instant Messaging, Lynn Kelly, James A. Keaten, Michael Hazel, Jason A. Williams

Psychology and Child Development

This study examined the relationship between reticence (Keaten & Kelly, 2000) and instant messaging (IM), including affect for IM, usage of IM, and self-perceived competence using IM in difficult interpersonal situations. Participants (N=336) from undergraduate courses responded to self-report measures of reticence, affect for IM, general usage of IM, as well as usage in challenging interpersonal situations, and communication competence. A structural equation model indicated that reduced anxiety and inhibition, IM competence, and increased preparation and control explained 34% of the variance in frequency of IM use in a difficult personal situation. Results showed that higher levels of reticence were …

Fostering Sustainable Operations In A Natural Resource Management Agency: Insights From The Field, Patricia L. Winter, Shawn M. Burn

Psychology and Child Development

Sustainable operations (SO; operating in an environmentally, economically, and socially sustainable manner) is consistent with the environmental stewardship mission of natural resource management organizations. This study sought to examine SO practices in the daily work lives of US Forest Service employees, including those primarily stationed in the office and in the field. The purpose was to identify influences on these behaviors such that organizations can more effectively promote them. We surveyed a random sample of employees within a region and research station of the US Forest Service (n = 451) regarding SO behaviors, barriers, and facilitators to SO, and perspectives …

Use Of Family Care Indicators And Their Relationship With Child Development In Bangladesh, Jena D. Hamadani, Fahmida Tofail, Afroza Hilaly, Syed N. Huda, Patrice L. Engle, Sally M. Grantham-Mcgregor

Psychology and Child Development

Poor stimulation in the home is one of the main factors affecting the development of children living in poverty. The family care indicators (FCIs) were developed to measure home stimulation in large populations and were derived from the Home Observations for Measurement of the Environment (HOME). The FCIs were piloted with 801 rural Bangladeshi mothers of children aged 18 months. Five subscales were created: ‘play activities’ (PA), ‘varieties of play materials’ (VP), ‘sources of play materials’, ‘household books’, and ‘magazines and newspapers’ (MN). All subscales had acceptable short-term reliability. Mental and motor development of the children was assessed on the …

Maternal Depression: A Global Threat To Children’S Health, Development, And Behavior And To Human Rights, Theodore D. Wachs, Maureen M. Black, Patrice L. Engle

Psychology and Child Development

Depressive disorders are a common source of disability among women. In addition to the economic and human costs of maternal depression, children of depressed mothers are at risk for health, developmental, and behavioral problems. Although most of the research examining the evidence and intergenerational aspects of maternal depression has been conducted in high-income countries, recent evidence suggests that rates of maternal depression may be higher in low- and middle-income countries, where nearly 90% of the world’s children live. This review examines the evidence from low- and middle-income countries that links maternal depression with children’s health, development, and behavior. We present …

Insincere Utterances And Gaze: Eye Contact During Sarcastic Statements, Jason A. Williams, Erin L. Burns, Elizabeth A. Harmon

Psychology and Child Development

Anecdotal evidence suggests that speakers often gaze away from their listeners during sarcastic utterances; however, this question has not been directly addressed empirically. This study systematically compared gaze-direction of speakers in dyadic conversation when uttering sincere and sarcastic statements. 18 naive participants were required to recite a series of contradictory statements on a single topic to a naive listener, while at the same time conveying their actual opinion about this topic. This latter task could only be accomplished through prosodic or nonverbal communication by indicating sincerity or insincerity (sarcasm) for the various statements and allowed examination of gaze across the …

When Dispositional And Role Power Fit: Implications For Self-Expression And Self-Other Congruence, Serena Chen, Carrie A. Langner, Rodolfo Mendoza-Denton

Psychology and Child Development

Integrating and extending the literatures on social power and person–environment fit, 4 studies tested the hypothesis that when people's dispositional beliefs about their capacity to influence others fit their assigned role power, they are more likely to engage in self-expression—that is, behave in line with their states and traits—thereby increasing their likelihood of being perceived by others in a manner congruent with their own self-judgments (i.e., self–other congruence). In Studies 1–3, dispositionally high- and low-power participants were randomly assigned to play a high- or low-power role in an interaction with a confederate. When participants' dispositional and role power fit (vs. …

A Situational Model Of Sexual Assault Prevention Through Bystander Intervention, Shawn Meghan Burn

Psychology and Child Development

Bystander intervention is a potentially potent tool in the primary prevention of sexual assault but more information is needed to guide prevention programs (Banyard 2008). Undergraduates (378 women and 210 men, primarily White) at a central coast California university completed an anonymous questionnaire measuring five barriers identified by the situational model of bystander intervention (Latane and Darley 1970) and bystander intervention behavior. As expected, the barriers were negatively correlated with intervention, were greater for men than for women, and intervention likelihood was affected by perceptions of victim worthiness, especially for men. Hypotheses predicting a positive relationship between having a relationship …

How Personalized And Socialized Power Motivation Facilitate Antisocial And Prosocial Decision-Making, Joe C. Magee, Carrie A. Langner

Psychology and Child Development

In two studies, we investigate the effects of individuals’ power motivation on decision-making. We distinguish between two types of power motivation [McClelland, D. C. (1970). The two faces of power. Journal of International Affairs, 24, 29–47; Winter, D. G. (1973). The power motive. New York: The Free Press] and demonstrate that both types of power motivation facilitate influential decision-making but that each type plays a different role in different contexts. In a conflict context (Study 1), individuals’ personalized (self-serving) power motivation was associated with antisocial decisions, and in a healthcare context (Study 2), individuals socialized (other-serving) power motivation …

A Behavioral Intervention Tool For Recreation Managers, Shawn Meghan Burn, Patricia L. Winter

Psychology and Child Development

Depreciative behaviors and other undesirable recreationist actions continue to be a topic of great interest for recreation management (fig. 1, above). Maintaining park ecosystems involves responding to and preventing damage from depreciative recreationist behavior, and recreation managers are charged with developing and selecting effective tools to address the costly and perplexing impacts of undesirable recreationist behavior.

This article describes the Environmental Intervention Handbook for Resource Managers (EIH), a tool we designed to help managers modify depreciative recreationist behavior. The handbook is based on a model of pro-environmental behavior change derived from social science research. It provides “treatments” of depreciative behavior …

The Effect Of Poverty On Child Development And Educational Outcomes, Patrice L. Engle, Maureen M. Black

Psychology and Child Development

Poverty affects a child’s development and educational outcomes beginning in the earliest years of life, both directly and indirectly through mediated, moderated, and transactional processes. School readiness, or the child’s ability to use and profit from school, has been recognized as playing a unique role in escape from poverty in the United States and increasingly in developing countries. It is a critical element but needs to be supported by many other components of a poverty alleviation strategy, such as improved opportunity structures and empowerment of families. The paper reviews evidence from interventions to improve school readiness of children in poverty, …

Social Power And Emotional Experience: Actor And Partner Effects Within Dyadic Interactions, Carrie A. Langner, Dacher Keltner

Psychology and Child Development

A dyadic methodological and statistical approach to social power is used to test the notion that an individual’s power and a partner’s power have distinct effects on the individual’s emotional experience. Two studies examined actor and partner effects of social power on emotion within dyadic interactions. Across interpersonal contexts and measures of social power, the individual’s own social power, theorized to activate behavioral approach, was associated with positive emotion (an actor effect). In contrast, being subject to a partner’s elevated social power, theorized to activate behavioral inhibition, was associated with increased negative emotion (a partner effect). The discussion focuses on …

Global Vor Gain Adaptation During Near Fixation To Foveal Targets, Jason A. Williams, Bruce Bridgeman, Tadg Woods, Robert Welch

Psychology and Child Development

Long-term rotational vestibulo-ocular (VOR) adaptation occurs during systematic dysmetria between visual and vestibular afferents, adjusting eye-rotation angular velocity to re-establish retinal stability of the visual field. Due to translational motion of the eyes during head rotation, VOR gain is higher when fixating near objects. The current study measures VOR in humans before and after 6min of exposure to a foveal near-target during sinusoidal whole-body rotation at 0.45 Hz. All of six participants showed post-exposure increases in open-loop VOR gain after fixating near targets, demonstrating a mean modulation increase of open-loop VOR gain from 0.86 before adaptation to 1.2 after adaptation. …
