We wondered whether genetic differences would also influence response bias in cases of ambiguous or even absurd items triggering an acquiescence bias to agree with even impossible question content. We examined the genetic predisposition for the acquiescence response bias in 257 families with twins. Both parents and twins completed a modified Wildman Symptoms Questionnaire and provided salivary DNA samples. From published genome-wide association studies (GWAS), we derived polygenic score (PGS) algorithms for indicators of SES (educational attainment [EA] and income) and for general intelligence (IQ), which were applied to the GWAS results of our participants' DNA. The twins (<i>N</i> = 514 children, 55% monozygotic pairs) were on average 7.92 years old (<i>SD</i> = 0.66), and 51.6% were female.

Higher PGSs for EA and income but not for IQ predicted less acquiescence response bias in parents and children.

This research and studies with older infants indicate that both the formation and the expansion of schemata occur through moderate discrepancies, a concept that Jerome Kagan promoted conceptually and through his research. Discrepancy, as distinct from novelty, is insufficiently acknowledged in the literature on schema theory. The schema is both cognitive and affective and develops in unison in a curvilinear pattern with a gradual onset and exponential expansion. Optimal attentiveness and positive affect occur at the peak of formation and to moderate discrepancies. Redundancy beyond the optimal level produces decreasing interest and positive affect and increasing negative affect resulting in boredom and avoidance. These characteristics of schema development are difficult to study with older children and adults. Rumelhart (1980) regarded the schema as the \"building block of cognition\" and Kagan (2002) called its expansion through moderate discrepancies an \"engine of change\" implying widespread application for cognition and behavior throughout life. Kagan urged the search for structure (form) as opposed to function in cognition, and the curvilinear pattern of schema development and its characteristics, it is argued, is the structure he sought.

In the present study, 51 mothers (all White; age <i>M</i> = 32 years, <i>SD</i> = 3; 70.8% monthly household income > 3,400 U.S. dollars) and their infants (39.2% female at birth) participated.

At 10-11 months, we assessed infants' resting electroencephalographic (EEG) 6-9 Hz frontal asymmetry (a marker of risk for maladaptive regulatory behaviors and withdrawal), infant fearful withdrawal, and infant empathic behavior. We found that maternal contingent responsiveness to 4-month-old infant's gaze in naturalistic interactions moderated the relation between 4-month infant negative reactivity and 11-month resting EEG asymmetry. Results suggest that maternal contingent responsiveness alters the extent to which early reactive tendencies end up \"embedded\" in infant brain activity profiles. Exploratory analyses revealed that the interaction between maternal contingent responsiveness and infant reactivity predicting infant resting EEG asymmetry, in turn predicted infants' fearful withdrawal and empathic behaviors also assessed at 10-11 months.

Jerome Kagan observed that the same behavior can occur for different reasons, and differing behaviors can occur for the same reason. To help account for persistence, desistence, and transformation of behavior across development, Kagan introduced various types of continuity and discontinuity of forms and functions of behavior. This framework provides opportunities for identifying explanatory mechanisms in behavior development. However, misconceptions remain in applying the concepts that Kagan introduced. Much of the literature assumes developmental continuity in constructs without examining whether assumptions are supported, leading to faulty developmental inferences. For instance, the use of the same measure across time to assess development assumes that the behavior occurs for the same reason across time (homotypic continuity). In addition, just because one behavior predicts a different behavior at a later time does not necessarily indicate that age-differing behaviors occur for the same reason (heterotypic continuity). This review aims to advance conceptualizations of continuity and discontinuity from a contemporary perspective with aims to improve mechanistic understanding of behavior development across the lifespan. To better align behaviors, functions, and mechanisms, research should (a) examine (dis)continuity of individual behaviors rather than merely syndromes, (b) identify the function(s) of the given behavior(s), and (c) identify the cognitive and biological processes that underlie the behavior-function pairs. Incorporating examples from research on development of humans and nonhuman animals, I discuss challenges from work that has followed Kagan's ideas and ways to advance understanding of continuity and discontinuity across development.

Although these topics have yielded an abundance of research, fewer studies have employed observational data during middle childhood, when unique environmental challenges could influence temperament development. To address this gap, Israeli twin children were observed at Age 6.5 (<i>N</i> = 1,083, 564 families; 50.6% females) and again at Age 8-9 (<i>N</i> = 768, 388 families; 52.0% females; 611 children from 322 families had data from both ages). Temperament was assessed globally by trained coders and, at Age 8-9, also by the experimenter who interacted with the child. We examined whether Rothbart et al.'s (2000) three-factor model, according to which temperament includes the domains negative affect, positive affect/surgency, and effortful control, emerges from the data. In addition, we considered a bifactor model, where a fourth global factor accounts for all behaviors' commonality. Across the two ages and rating methods, confirmatory factor analyses supported the bifactor model. The global factor's loadings suggested that it reflects children's expressiveness. Adding this factor changed the associations between the other factors and enabled differentiation between surgency and positive affect. This suggests that in observational settings that capture temperament impressions holistically, children's expressiveness affects other traits' behavioral displays. Twin models revealed genetic influences for most traits. Importantly, twin models revealed shared-environmental influences for negative affect and expressiveness, which modestly contributed to temperament consistency across ages. These findings shed light on temperament traits' interrelatedness and stress the importance of the shared environment to temperament development during middle childhood.

Although early childhood is a period of rapid telomere attrition, little is known about the factors that influence telomere biology during this time.

This study's goal was to test associations among repeated measures of temperament and telomere length in a community sample of children (<i>N</i> = 602; 52% male, 73% non-Hispanic White, middle-to-high socioeconomic status) from infancy to age 3 years.

Temperament was assessed via maternal report questionnaires administered at infancy (Infant Behavior Report Questionnaire-Revised) and ages 2 and 3 years (Early Childhood Behavior Questionnaire). Temperament was operationalized in two ways: using the established domains of negative affectivity, surgency/extraversion, and regulation/effortful control and using person-centered scores that identified three groups of children with similar profiles across domains (emotionally and behaviorally regulated; emotionally and behaviorally dysregulated; introverted and overcontrolled). Analyses revealed that greater regulation/effortful control was associated with longer telomere length across time points. Additionally, higher surgency/extraversion, beginning in infancy, was associated with decreased rate of telomere attrition. There were no sex differences in the relations between temperament and telomere measures. These findings suggest that, as early as infancy, temperament may influence telomere biology, with a potential protective effect of positive temperament characteristics on telomere erosion.
