Item Capturing Age-group Differences and Developmental Change with the BASC Parent Rating Scales(Journal of Applied Developmental Psychology, 7/1/2015) Barbot, Baptiste; Hein, Sascha D.; Luthar, Suniya S.; Grigorenko, Elena L.Estimation of age-group differences and intra-individual change across distinct developmental periods is often challenged by the use of age-appropriate (but non-parallel) measures. We present a short version of the Behavior Assessment System (Reynolds & Kamphaus, 1998), Parent Rating Scales for Children (PRS-C) and Adolescents (PRS-A), which uses only their common-items to derive estimates of the initial constructs optimized for developmental studies. Measurement invariance of a three-factor model (Externalizing, Internalizing, Adaptive Skills) was tested across age-groups (161 mothers using PRS-C; 200 mothers using PRS-A) and over time (115 mothers using PRS-C at baseline and PRS-A five years later) with the original versus short PRS. Results indicated that the short PRS holds a sufficient level of invariance for a robust estimation of age-group differences and intra-individual change, as compared to the original PRS, which held only weak invariance leading to flawed developmental inferences. Importance of test-content parallelism for developmental studies is discussed.Item Differences in Judgments of Creativity: How Do Academic Domain, Personality, and Self-Reported Creativity Influence Novice Judges’ Evaluations of Creative Productions?(Journal of Intelligence, 9/14/2015) Tan, Mei; Mourgues, Catalina V.; Hein, Sascha D.; MacCormick, John; Barbot, Baptiste; Grigorenko, Elena L.Intelligence assessment is often viewed as a narrow and ever-narrowing field, defined (as per IQ) by the measurement of finely distinguished cognitive processes. It is instructive, however, to remember that other, broader conceptions of intelligence exist and might usefully be considered for a comprehensive assessment of intellectual functioning. This article invokes a more holistic, systems theory of intelligence—the theory of successful intelligence—and examines the possibility of including in intelligence assessment a similarly holistic measure of creativity. The time and costs of production-based assessments of creativity are generally considered prohibitive. Such barriers may be mitigated by applying the consensual assessment technique using novice raters. To investigate further this possibility, we explored the question: how much do demographic factors such as age and gender and psychological factors such as domain-specific expertise, personality or self-perceived creativity affect novices’ unidimensional ratings of creativity? Fifty-one novice judges from three undergraduate programs, majoring in three disparate expertise domains (i.e., visual art, psychology and computer science) rated 40 child-generated Lego creatures for creativity. Results showed no differences in creativity ratings based on the expertise domains of the judges. However, judges’ personality and self-perception of their own everyday creativity appeared to influence the way they scored the creatures for creativity.Item Epigenetic Patterns Modulate the Connection between Developmental Dynamics of Parenting and Offspring Psychosocial Adjustment(Child Development, 1/1/2017) Naumova, Oksana Yu; Hein, Sascha D.; Suderman, Matthew; Barbot, Baptiste; Lee, Maria; Raefski, Adam; Dobrynin, Pavel V.; Brown, Pamela J.; Szyf, Moshe; Luthar, Suniya S.; Grigorenko, Elena L.This study attempted to establish and quantify the connections between parenting, offspring psychosocial adjustment, and the epigenome. The participants, 35 African-American young adults (19 females and 16 males; age = 17 to 29.5 years), represented a subsample of a three-wave longitudinal 15-year study on the developmental trajectories of low-income urban mother-offspring dyads. Mothers were assessed on their perceptions of maternal stress at each wave. Offspring were assessed on their perceptions of maternal parenting at each wave and on their adaptive and maladaptive behavior at the last wave. Genome-wide DNA methylation in peripheral T-lymphocytes at the third wave was assayed using MBD-sequencing. Statistically significant associations were identified between the change in offspring's perception of parenting from middle childhood to adulthood and the DNA methylation in offspring's adult genomes. Specifically, the slope of perceived parental rejection across the three time points was related to an increase in methylation, or a potential downregulation, of 565 genes thought to be involved in the control of a broad spectrum of biological functions generally related to cellular signaling. A subset of these epigenetic marks, clustered in 23 genes, some of which participate in the development and functioning of the CNS, were in turn associated with psychosocial adjustment as captured by interpersonal relationships and emotional self-evaluation. This appears to be one of the first investigations of the modulating role of the methylome in associations between developmental dynamics of parenting throughout the formative years of child and adolescent development and psychosocial adjustment in adulthood.Item Identifying Learning Patterns of Children at Risk for Specific Reading Disability(Developmental Science, 5/1/2017) Barbot, Baptiste; Krivulskaya, Suzanna; Hein, Sascha D.; Reich, Jodi; Thuma, Philip E.; Grigorenko, Elena L.Differences in learning patterns of vocabulary acquisition in children at risk (+SRD) and not at risk (SRD) for Specific Reading Disability (SRD) were examined using a microdevelopmental paradigm applied to the multi-trial Foreign Language Learning Task (FLLT; Baddeley et al., 1995). The FLLT was administered to 905 children from rural Chitonga-speaking Zambia. A multi-group Latent Growth Curve Model (LGCM) was implemented to study interindividual differences in intraindividual change across trials. Results showed that the +SRD group recalled fewer words correctly in the first trial, learned at a slower rate during the subsequent trials, and demonstrated a more linear learning pattern compared to the SRD group. This study illustrates the promise of LGCM applied to multi-trial learning tasks, by isolating three components of the learning process (initial recall, rate of learning, and functional pattern of learning). Implications of this microdevelopmental approach to SRD research in low-to-middle income countries are discussed.
