Item Promoting broad and stable improvements in low-income children’s numerical knowledge through playing number board games(2008) Ramani, Geetha B.; Siegler, Robert S.Item Neuroimaging studies of pediatric social anxiety: paradigms, pitfalls and a new direction for investigating the neural mechanisms(Springer Nature, 2013-07-12) Jarcho, Johanna M; Leibenluft, Ellen; Walker, Olga Lydia; Fox, Nathan A; Pine, Daniel S; Nelson, Eric ESocial Anxiety Disorder (SAD) is a common and debilitating condition that typically manifests in adolescence. Here we describe cognitive factors engaged by brain-imaging tasks, which model the peer-based social interactions that evoke symptoms of SAD. We then present preliminary results from the Virtual School paradigm, a novel peer-based social interaction task. This paradigm is designed to investigate the neural mechanisms mediating individual differences in social response flexibility and in participants’ responses to uncertainty in social contexts. We discuss the utility of this new paradigm for research on brain function and developmental psychopathology.Item Using a high-dimensional graph of semantic space to model relationships among words(Frontiers in Psychology, 2014-05-12) Jackson, Alice F.; Bolger, Donald J.The GOLD model (Graph Of Language Distribution) is a network model constructed based on co-occurrence in a large corpus of natural language that may be used to explore what information may be present in a graph-structured model of language, and what information may be extracted through theoretically-driven algorithms as well as standard graph analysis methods. The present study will employ GOLD to examine two types of relationship between words: semantic similarity and associative relatedness. Semantic similarity refers to the degree of overlap in meaning between words, while associative relatedness refers to the degree to which two words occur in the same schematic context. It is expected that a graph structured model of language constructed based on co-occurrence should easily capture associative relatedness, because this type of relationship is thought to be present directly in lexical co-occurrence. However, it is hypothesized that semantic similarity may be extracted from the intersection of the set of first-order connections, because two words that are semantically similar may occupy similar thematic or syntactic roles across contexts and thus would co-occur lexically with the same set of nodes. Two versions the GOLD model that differed in terms of the co-occurence window, bigGOLD at the paragraph level and smallGOLD at the adjacent word level, were directly compared to the performance of a well-established distributional model, Latent Semantic Analysis (LSA). The superior performance of the GOLD models (big and small) suggest that a single acquisition and storage mechanism, namely co-occurrence, can account for associative and conceptual relationships between words and is more psychologically plausible than models using singular value decomposition (SVD).Item The Contributions of Segmental and Suprasegmental Information in Reading Chinese Characters Aloud(PLOS (Public Library of Science), 2015-11-09) Wang, Min; Li, Chuchu; Lin, Candise Y.The Chinese writing system provides an excellent case for testing the contribution of segmental and suprasegmental information in reading words aloud within the same language. In logographic Chinese characters, neither segmental nor tonal information is explicitly represented, whereas in Pinyin, an alphabetic transcription of the character, both are explicitly represented. Two primed naming experiments were conducted in which the targets were always written characters. When logographic characters served as the primes (Experiment 1), syllable segmental and tonal information appeared to be represented and encoded as an integral unit which in turn facilitated target character naming. When Pinyin served as the primes (Experiment 2), the explicit phonetic representation facilitated encoding of both segmental and suprasegmental information, but with later access to suprasegmental information. In addition, Chinese speakers were faster to name characters than Pinyin in a simple naming task (Experiment 3), suggesting that Pinyin may be read via a phonological assembly route, whereas characters may be read via a lexical route. Taken together, our findings point to the need to consider the contributions of both segmental and suprasegmental information and the time course in the well-established models for reading aloud, as well as the cognitive mechanisms underlying the reading aloud of logographic characters versus alphabetic Pinyin script.Item The Creative Stereotype Effect(PLOS (Public Library of Science), 2016-02-10) Dumas, Denis; Dunbar, Kevin N.Because of its fundamental relevance to scientific innovation, artistic expression, and human ingenuity, creativity has long been the subject of systematic psychological investigation. Concomitantly, the far-reaching effects of stereotypes on various cognitive and social processes have been widely researched. Bridging these two literatures, we show in a series of two studies that stereotypes related to creativity can both enhance and diminish individuals’ performance on a divergent thinking task. Specifically, Study 1 demonstrated that participants asked to take on a stereotypically uninhibited perspective performed significantly better on a divergent thinking task than those participants who took on a stereotypically inhibited perspective, and a control group. Relatedly, Study 2 showed that the same effect is found within-subjects, with divergent thinking significantly improving when participants invoke an uninhibited stereotype. Moreover, we demonstrate the efficacy of Latent Semantic Analysis as an objective measure of the originality of ideas, and discuss implications of our findings for the nature of creativity. Namely, that creativity may not be best described as a stable individual trait, but as a malleable product of context and perspective.Item Age-Related Changes in Children’s Associations of Economic Resources and Race(Frontiers, 2016-06-16) Elenbaas, Laura; Killen, MelanieAge-related changes in children’s associations of economic resources and race were investigated. The sample (N = 308) included 5–6 year-olds (n = 153, M = 6.01 years, SD = 0.33 years) and 10–11 year-olds (n = 155, M = 11.12 years, SD = 0.59 years) of African–American (n = 93), European–American (n = 92), Latino (n = 62), Asian– American (n = 23), and multi-racial or multi-ethnic (n = 26) background. Participants matched pairs of target children (African–American and European–American) with visual indicators of low, middle, and high economic status. Children’s associations of economic resources with racial groups changed with age, and reflected different associations at high, middle, and low levels of the economic spectrum. Specifically, children associated targets of both races with middle economic status at a comparable rate, and with age, increasingly associated targets of both races with indicators of middle economic status. By contrast, both younger and older children associated African–American targets with indicators of low economic status more frequently than European–American targets. Finally, children associated African–American targets with indicators of high economic status less frequently with age, resulting in a perceived disparity in favor of European–American targets at high economic status among older children that was not present among younger children. No differences were found by participants’ own racial or ethnic background. These results highlight the need to move beyond a dichotomized view (rich or poor) to include middle economic status when examining children’s associations of economic resources and race.Item Assessing Differential Item Functioning on the Test of Relational Reasoning(Frontiers, 2018-03-02) Dumas, Denis; Alexander, PatriciaThe test of relational reasoning (TORR) is designed to assess the ability to identify complex patterns within visuospatial stimuli. The TORR is designed for use in school and university settings, and therefore, its measurement invariance across diverse groups is critical. In this investigation, a large sample, representative of a major university on key demographic variables, was collected, and the resulting data were analyzed using a multi-group, multidimensional item-response theory model-comparison procedure. No significant differential item functioning was found on any of the TORR items across any of the demographic groups of interest. This finding is interpreted as evidence of the cultural fairness of the TORR, and potential test-development choices that may have contributed to that cultural fairness are discussed.Item Space and Math Wave One and Wave Two v.1(2018-07-19) Mix, Kelly S.; Levine, Susan C.This dataset contains test scores for two waves of data collected from kindergarten, third grade, and sixth grade students in 2013 and 2014, respectively. Measures included age-appropriate spatial and mathematics tasks.Item The Time Course of Activation of Semantic and Orthographic Information in Morphological Decomposition by Korean Adults and Developing Readers(Frontiers, 2018-11) Lin, Candise Y.; Wang, Min; Ko, YeongThe current study examined the involvement of semantic and orthographic information in the processing of derived words in Korean Hangul. Sixth grade children and adults participated in four masked priming lexical decision experiments in which the prime duration varied from 36, 48, 57, and 72ms (in Experiments, 1, 2, 3, and 4, respectively). Morphological (M), semantic (S), and orthographic (O) relatedness between prime-target pairs were manipulated. There were four types of Korean prime-target pairs: (1) -M-S+O: , scandal-scan, (2) +M-S+O: , archer-arch, (3) +M+S+O: , bravely-brave, and (4) -M+S-O: , accuse-blame. There were several key findings: (1) adults showed significant priming effects at 57 and 72ms in +M+S+O and significant priming effects at 72ms in +M-S+O; (2) less skilled readers showed significant facilitation at 36ms in +M+S+O; and (3) in -M-S+O, both skilled and less skilled readers show significant inhibition across four prime durations. The different time course of +M+S+O priming for adults and children may be due to developing readers’ smaller lexicon and less competition for semantic activation of the monosyllabic suffix (e.g., in ), which is a homograph in Korean Hangul. The consistent orthographic inhibition for both age groups suggest that orthographic information is activated early and continues to play an important role throughout the course of Korean visual word recognition. The current study extends previous research with readers of Roman alphabets to readers of an alpha-syllabary orthography written in a non-linear spatial layout with more clear-cut syllable boundaries. Taken together, it appears that the involvement of semantic and orthographic information in the decomposition of morphologically complex word may vary depending on the characteristics of the orthography.Item K-2 Place Value Longitudinal Study (2017-2019)(2018-11-27) Mix, Kelly S.; Smith, Linda B.Children were tested with a battery of place value concept tasks as well as mathematics outcomes, in kindergarten, first and second grades.Item Spatial Training and Math Outcomes - Grades 1 and 6(2019-12-06) Mix, Kelly S.; Levine, Susan C.First and sixth grade students were pretested and posttested using a variety of mathematics outcome measures. In between the testing sessions, children received one of two kinds of spatial training, or participated in a language training control condition.Item Students’ Scientific Evaluations of Water Resources(MDPI, 2020-07-18) Medrano, Josh; Jaffe, Joshua; Lombardi, Doug; Holzer, Margaret A.; Roemmele, ChristopherSocially-relevant and controversial topics, such as water issues, are subject to differences in the explanations that scientists and the public (herein, students) find plausible. Students need to be more evaluative of the validity of explanations (e.g., explanatory models) based on evidence when addressing such topics. We compared two activities where students weighed connections between lines of evidence and explanations. In one activity, students were given four evidence statements and two models (one scientific and one non-scientific alternative); in the other, students chose four out of eight evidence statements and three models (two scientific and one non-scientific). Repeated measures analysis of variance (ANOVA) showed that both activities engaged students’ evaluations and differentially shifted students’ plausibility judgments and knowledge. A structural equation model suggested that students’ evaluation may influence post-instructional plausibility and knowledge; when students chose their lines of evidence and explanatory models, their evaluations were deeper, with stronger shifts toward a scientific stance and greater levels of post-instructional knowledge. The activities may help to develop students’ critical evaluation skills, a scientific practice that is key to understanding both scientific content and science as a process. Although effect sizes were modest, the results provided critical information for the final development and testing stage of these water resource instructional activities.Item K Place Value Intervention Study (2019-2020)(2021-06-14) Mix, Kelly S.; Smith, Linda B.Kindergartners were pre- and post-tested with a battery of place value concept tasks as well as mathematics outcomes after a 20-lesson intervention of place value instruction. Children were randomly assigned to either the instruction or active control group.

To examine whether a childhood temperament characterized by shyness and avoidance of social interactions is associated with poor cardiometabolic health. This cohort study included participants who were recruited at birth between April 1991 to December 1992 as part of a prospective longitudinal cohort, the Avon Longitudinal Study of Parents and Children. Follow-up assessments of health behaviors and cardiometabolic health extended into young adulthood (age 24 years). Data analysis was conducted between April and October 2021. Parent reports of temperament across ages 3 to 6 years were used to derive childhood temperament profiles in a longitudinal clustering analysis. Accelerometry measures of adolescent moderate to vigorous physical activity (MVPA) from ages 11 to 15 years and adult social occupation class were examined as mediators using path analyses. At age 24 years, 9 cardiometabolic outcomes were measured through anthropometrics and fasting blood samples: triglyceride levels, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol levels, glycated hemoglobin levels, insulin levels, systolic and diastolic blood pressure, body mass index, and C-reactive protein (CRP) levels. Of the 9491 participants included in the analyses, 4908 (51.7%) were male, and 8668 of 9027 (96.0%) were White. Four childhood temperament profiles were identified: (1) introverted (2810 [29.6%]), (2) extraverted (2527 [26.6%]), (3) conflicted-shy (2335 [24.6%]), and (4) avoidant-shy (1819 [19.2%]). Lower childhood socioeconomic status was a precursor associated with the development of an avoidant-shy temperament (eg, introvert vs avoidant-shy: odds ratio, 1.13; 95% CI, 1.04-1.23). Path analyses showed that avoidant-shy children spent less time in MVPA in adolescence compared with all other temperament profiles (eg, introvert vs avoidant-shy: β = 0.10; b = 0.25; 95% CI, 0.14-0.35; P < .001), which in turn was associated with a cluster of cardiometabolic indices at age 24 years, including lower HDL cholesterol levels (β = 0.07; b = 0.95; 95% CI, 0.12-1.78; P = .03) and higher LDL cholesterol levels (β = −0.07; b = −1.69; 95% CI = −3.32 to −0.06; P = .04), insulin levels (β = −0.10; b = −0.57; 95% CI, −1.04 to −0.10; P = .02), diastolic blood pressure (β = −0.09; b = −0.59; 95% CI, −0.97 to −0.21; P = .002), and body mass index (β = −0.07; b = −0.32; 95% CI, −0.56 to −0.07; P = .01). Additionally, children classified as avoidant-shy attained lower social occupation classes at age 24 years, which was concurrently associated with higher BMI (β = 0.06; b = 0.21; 95% CI, 0.08-0.35; P = .002). Notably, these results were adjusted for a range of early developmental precursors and confounders, suggesting an independent association of temperament. In this cohort study, less engagement in physical activity across adolescence seemed to be a developmental mechanism connecting an avoidant-shy childhood temperament and greater cardiometabolic risks over the life course. Future studies should examine the efficacy of physical activity and social skill programs that specially target the needs of different children to thereby reduce cardiometabolic risks.Item Maternal depressive symptoms and child behavior problems: Attachment security as a protective factor(Cambridge University Press, 2022-01-31) Whittenburg, Paige N.; Stern, Jessica A.; Brett, Bonnie E.; Straske, M. Davis; Cassidy, JudeMaternal depressive symptoms (MDS) have been linked to both child internalizing and externalizing behavior problems. Theory suggests that child attachment security may be a protective factor against the negative effects of MDS. This study examined child attachment security as a buffer of the link between MDS and child internalizing and externalizing behavior problems at two time points in a predominantly African American sample. Participants included mothers (N = 164; M age = 29.68 years; 76% African American) and their preschool-aged children (60% girls; M age = 44.67 months) recruited from four Head Start centers in low-income neighborhoods in Baltimore, Maryland. MDS were concurrently associated with child internalizing and externalizing behavior problems at both time points. No significant main effects of child attachment security on behavior problems emerged; however, child attachment moderated the association between MDS and child internalizing behavior problems at Time 2, such that MDS predicted greater child internalizing problems when attachment security was low, and the effect was attenuated when attachment security was high. No interaction emerged for child externalizing problems. Findings suggest that secure attachment in early childhood can serve as a protective factor in the context of parental risk. We discuss implications for intervention and the intergenerational transmission of psychopathology.Item Phonological Training and Word Learning in a Novel Language(Frontiers, 2022-02-17) Li, Yixun; Wang, Min; Li, Chuchu; Li, ManIn reading Chinese words, learners may process segment and tone either separately or as an integral unit, as evidenced in previous research. The present study compared two ways—Segmental versus Whole-Syllable-Based Training—for improving learners’ phonological and word learning in Chinese as a novel language, while controlling for learners’ musical ability, an important factor that may contribute to phonological learning. Forty-two American college students learned Chinese words represented by Pinyin, a Romanized script which denotes the pronunciation of Chinese characters. Before the training, all participants were introduced to the phonology and Pinyin system. Then, they were trained on the pronunciation and meaning of the Pinyin words with or without an emphasis on separating the tonal from segmental information. All participants’ musical ability was assessed using a musical ability test. Learning outcomes were measured through tasks of same-different phonological judgment, tone identification, and word comprehension. Results showed the equal success of the two training methods, probably due to the consistent involvement of Pinyin and learner’s reliance on segment and tone as an integral unit rather than separate cues in phonological and word learning. Furthermore, musical ability seems to play a role in phonological and word learning among novel learners of Chinese.Item Commentary: Recognizing our similarities and celebrating our differences – parenting across cultures as a lens toward social justice and equity(Wiley, 2022-03-07) Cabrera, Natasha J.Lansford (2022) has aptly and eloquently reviewed the vast scholarly research on cross-cultural parenting and concludes that similarities in parenting norms and behaviors across cultures reflect universally adaptive behaviors for children’s development. Culture-specific differences are due largely to environmental constraints and affordances as well as cultural norms for expected behavior. This is an exemplar review that tells a clear story of what we have learned from the decades of research on this topic and lays the foundation for future scholarship. Specially compelling is Lansford’s argument that we need to take stock of what we know and conduct more of this type of research because the majority of what we have now is biased and does not represent the parenting practices of an increasingly diverse population. In this commentary, I provide some context for the value and potential pitfalls of cross-cultural research; discuss the importance of theoretically driven research; discuss the benefits of cross-cultural research; and conclude with some ideas for future investigations.Item Unconditional cash transfers and maternal substance use: findings from a randomized control trial of low-income mothers with infants in the U.S.(Springer Nature, 2022-05-05) Yoo, Paul Y.; Duncan, Greg J.; Magnuson, Katherine; Fox, Nathan A.; Yoshikawa, Hirokazu; Halpern-Meekin, Sarah; Noble, Kimberly G.Policy debates over anti-poverty programs are often marked by pernicious stereotypes suggesting that direct cash transfers to people residing in poverty encourage health-risking behaviors such as smoking, drinking, and other substance use. Causal evidence on this issue is limited in the U.S. Given the prominent role of child allowances and other forms of cash assistance in the 2021 American Rescue Plan and proposed Build Back Better legislation, evidence on the extent to which a monthly unconditional cash gift changes substance use patterns among low-income mothers with infants warrants attention, particularly in the context of economic supports that can help improve early environments of children. We employ a multi-site, parallel-group, randomized control trial in which 1,000 low-income mothers in the U.S. with newborns were recruited from hospitals shortly after the infant’s birth and randomly assigned to receive either a substantial ($333) or a nominal ($20) monthly cash gift during the early years of the infant’s life. We estimate the effect of the unconditional cash transfer on self-report measures of maternal substance use (i.e., alcohol, cigarette, or opioid use) and household expenditures on alcohol and cigarettes after one year of cash gifts. The cash gift difference of $313 per month had small and statistically nonsignificant impacts on group differences in maternal reports of substance use and household expenditures on alcohol or cigarettes. Effect sizes ranged between − 0.067 standard deviations and + 0.072 standard deviations. The estimated share of the $313 group difference spent on alcohol and tobacco was less than 1%. Our randomized control trial of monthly cash gifts to mothers with newborn infants finds that a cash gift difference of $313 per month did not significantly change maternal use of alcohol, cigarettes, or opioids or household expenditures on alcohol or cigarettes. Although the structure of our cash gifts differs somewhat from that of a government-provided child allowance, our null effect findings suggest that unconditional cash transfers aimed at families living in poverty are unlikely to induce large changes in substance use and expenditures by recipients.Item Group Norms Influence Children’s Expectations About Status Based on Wealth and Popularity(Frontiers, 2022-05-11) Yee, Kathryn M.; Glidden, Jacquelyn; Killen, MelanieChildren’s understanding of status and group norms influence their expectations about social encounters. However, status is multidimensional and children may perceive status stratification (i.e., high- and low-status) differently across multiple status dimensions (i.e., wealth and popularity). The current study investigated the effect of status level and norms on children’s expectations about intergroup affiliation in wealth and popularity contexts. Participants (N = 165; age range: 5–10 years; Mage = 7.72 years) were randomly assigned to hear two scenarios where a high- or low-status target affiliated with opposite-status groups based on either wealth or popularity. In one scenario, the group expressed an inclusive norm. In the other scenario, the group expressed an exclusive norm. For each scenario, children made predictions about children’s expectations for a target to acquire social resources. Novel findings indicated that children associated wealth status to some extent, but they drew stronger inferences from the wealth dimension than from the popularity dimension. In contrast to previous evidence that children distinguish between high- and low-status groups, we did not find evidence to support this in the context of the current study. In addition, norms of exclusion diminished children’s expectations for acquiring social resources from wealth and popularity groups but this effect was more pronounced between wealth groups. We found age differences in children’s expectations in regards to norms, but not in regards to status. The implications of how these effects, in addition to lack of effects, bear on children’s expectations about acquiring resources are discussed.Item Testing the effectiveness of the Developing Inclusive Youth program: A multisite randomized control trial(Wiley, 2022-05-25) Killen, Melanie; Burkholder, Amanda R.; D'Esterre, Alexander P.; Sims, Riley N.; Glidden, Jacquelyn; Yee, Kathryn M.; Luken Raz, Katherine V.; Elenbaas, Laura; Rizzo, Michael T.; Woodward, Bonnie; Samuelson, Arvid; Sweet, Tracy M.; Stapleton, Laura M. Killen, M., Burkholder, A. R., D’Esterre, A. P., Sims, R. N., Glidden, J., Yee, K. M., Luken Raz, K. V., Elenbaas, L., Rizzo, M. T., Woodward, B., Samuelson, A., Sweet, T. M., Stapleton, L. M. (2022). Testing the effectiveness of the Developing Inclusive Youth program: A multisite randomized control trial. Child Development, 93, 732–750.The Developing Inclusive Youth program is a classroom-based, individually administered video tool that depicts peer-based social and racial exclusion, combined with teacher-led discussions. A multisite randomized control trial was implemented with 983 participants (502 females; 58.5% White, 41.5% Ethnic/racial minority; Mage = 9.64 years) in 48 third-, fourth-, and fifth-grade classrooms across six schools. Children in the program were more likely to view interracial and same-race peer exclusion as wrong, associate positive traits with peers of different racial, ethnic, and gender backgrounds, and report play with peers from diverse backgrounds than were children in the control group. Many approaches are necessary to achieve antiracism in schools. This intervention is one component of this goal for developmental science.
