Comparing Self-Regulation-Associated Event Related Potentials in Preschool Children with and without High Levels of Disruptive Behavior

Deficient self-regulation plays a key role in the etiology of early onset disruptive behavior disorders and signals risk for chronic psychopathology. However, to date, there has been no research comparing preschool children with and without high levels of disruptive behavior using Event Related Potentials (ERPs) associated with specific self-regulation sub-processes. We examined 15 preschool children with high levels of disruptive behavior (35 % female) and 20 peers with low disruptive behavior (50 % female) who completed a Go/No-go task that provided emotionally valenced feedback. We tested whether 4 ERP components: the Error Related Negativity, the Error Positivity, the Feedback Related Negativity, and the No-go N2, differed in preschool children with and without high levels of disruptive behavior. Preschoolers with high levels of disruptive behavior showed less differentiation between the Error Positivity and corresponding waveforms following correct responses at posterior sites. Preschoolers with high and low disruptive behavior also showed differences in Go/No-go N2 waveform amplitudes across electrodes. These findings suggest that preschool children with high levels of disruptive behavior may show abnormal brain activity during certain self-regulation sub-processes, informing potential advances in conceptualizing and treating early disruptive behavior.     

Literacy: The End and Means of Literature

In modern times a gap has appeared between the arts of history and literature, and the sciences of historicism and criticism. Many modern critics, historians, and teachers of literature and history (and even many so‐called authors of literature) have welcomed, or at least complied with, the “scientification” of their arts, resulting in widespread illiteracy with regard to literature and history. The solution to this problem lies in a (re‐)investigation of how the art of literature teaches us the truth. I maintain that the lifeblood of literature is the set of common joys and griefs, the common blessings and sufferings, of mankind. Without a communication of these passions as passions with the result of a transformation or shaping of the soul – without a mimesis, as the Greeks would say –across the boundaries of tribe, race, gender and era, there is no literature; and no literacy. Using a scene from Solzhenitsyn's First Circle, I argue that these passions are part of the truth (or falsity) of any story involving human beings. So literature and history would both be restored if the writers, readers, and teachers of each developed a deeper concern for the whole truth.     

The nature of skilled adult reading varies with type of instruction in childhood

Does the type of reading instruction experienced during the initial years at school have any continuing effect on the ways in which adults read words? The question has arisen in current discussions about computational models of mature word-reading processes. We tested predicted continuing effects by comparing matched samples of skilled adult readers of English who had received explicit phonics instruction in childhood and those who had not. In responding to nonwords that can receive alternative legitimate pronunciations, those adults having childhood phonics instruction used more regular grapheme-phoneme correspondences that were context free and used fewer vocabulary-based contextually dependent correspondences than did adults who had no phonics instruction. These differences in regularization of naming responses also extended to some low-frequency words. This apparent cognitive footprint of childhood phonics instruction is a phenomenon requiring consideration when researchers attempt to model adult word reading and when they select participants to test the models.     

Development of conduct problems and peer rejection in preschool children: A social systems analysis

The development of impulsive-aggressive problem behavior and peer rejection was examined in sixty 4- to 5-year-old boys from low-income family backgrounds. Children's sociometric status and behavioral adjustment were assessed longitudinally at the beginning and end of the preschool year, and related to measures of peer interaction at three different points in time. Boys identified as socially rejected and aggressive in the beginning of the year were highly likely to be identified as such at the end of the year. Early in the preschool year, these children contributed to their own rejection by initiating socially aversive exchanges with peers. Although peers clearly perceived these problems, they did not reciprocate with counteraggression at first. However, as time passed, peers began to actively victimize these children, and most of the aggression on the part of victims became reactive in nature. Thus, the current findings strongly support a transactional model of the development of early peer rejection and conduct problems.The author is indebted to the Head Start teachers, children, and parents who participated, and to the following individuals for their invaluable help with data collection and coding: Margo Bonner, Beth O'Connell, Cindy Friedman, Elizabeth Jamner, Karen Lifgren, Marina Post, Jacqueline Raznick, Lisa Walsh, and Karen Weitzner.     

The development of infants' preference for motherese

Generally, infants prefer infant-directed (ID) to adult-directed (AD) speech. Mostly, researchers have used unfamiliar female voices in these studies. We investigated preferences for maternal ID speech in 1- and 4-month-olds. Using a procedure in which infants controlled access to voices by fixating a visual display, infants listened to recordings of natural female ID and AD speech. In Experiment 1, 1-month-olds heard recordings of maternal ID and AD speech, but these infants showed no preference for maternal ID speech. In Experiment 2, 1-month-olds heard the same ID and AD speech tapes but were not familiar with the speakers. Contrary to Experiment 1, these infants preferred ID speech. In Experiment 3, 4-month-olds heard recordings of maternal ID and AD speech and showed a significant preference for ID speech. Collectively, these results suggest that infant attention to ID speech depends on both speaker-general and speaker-specific characteristics, with interesting developmental changes occuring during early infancy.     

The effects of sex-role taking on children's responses to aggressive conflict situations

The effects of sex-role taking on children's responses to aggressive conflict situations were investigated in the present study. Subjects were 40 boys and girls aged 8–9, who were asked to take the role of boy and girl story characters involved in the following kinds of aggressive situations: victim of a verbal attack, victim of a physical attack, and witness to an attack upon a friend. A significant interaction effect between type of conflict situation and sex of story character was obtained. Subjects expected boy characters to retaliate more strongly than girl characters when intervening in an attack upon a friend, and girl characters to retaliate more strongly than boy characters when being verbally or physically assaulted. These findings suggest the importance of situational factors in determining children's sex-stereotyped expectations for aggressive retaliation.     

Perceived duration,visual persistence,and neural integration

Varying stimulus intensity while measuring the perceived duration/visual persistence of brief light flashes has yielded disparate results. Some studies have found a direct relationship between the two variables; others have found an inverse relationship. Several models have been suggested to unify this behavioral literature. They invoke the absolute intensity and the nature of the judgment as explanatory variables. We now present physiological data whose analysis was motivated by these models. We measured the duration of photoreceptor potentials as a function of light intensity and response measure. One response measure was. the length of time required for the response to decline from the peak by a criterion amount. The other response measure was the length of time a response stayed above a criterion level. These data suggest that each behaviorally based model captured a different aspect of a single underlying mechanism and that a melding of the two critical concepts would harmonize all of the results: In this melding, the sensory signals that mediate visual perception would have the type of complex intensity- and time-dependent properties found in real neural responses.     

Mapping the Growth of Heterogeneous Forms of Externalizing Problem Behavior Between Early Childhood and Adolescence:A Comparison of Parent and Teacher Ratings

We compared long-term growth patterns in teachers’ and mothers’ ratings of Overt Aggression, Covert Aggression, Oppositional Defiance, Impulsivity/inattention, and Emotion Dysregulation across developmental periods spanning kindergarten through grade 8 (ages 5 to 13 years). We also determined whether salient background characteristics and measures of child temperament and parenting risk differentially predicted growth in discrete categories of child externalizing symptoms across development. Participants were 549 kindergarten-age children (51% male; 83% European American; 17% African American) whose problem behaviors were rated by teachers and parents each successive year of development through 8th grade. Latent growth curve analyses were performed for each component scale, contrasting with an overall index of externalizing, in a piecewise fashion encompassing two periods of development: K-1and grades 1–8. Our findings showed that there were meaningful differences and similarities between informants in their levels of concern about specific forms of externalizing problems, patterns of change in problem behavior reports across development, and in the extent to which their ratings of specific problems were associated with distal and proximal covariates. Thus, these data provided novel information about issues that have received scant empirical attention and have important implications for understanding the development and prevention of children’s long-term externalizing problems.     

Emotional Expressiveness during Peer Conflicts: A Predictor of Social Maladjustment among High-Risk Preschoolers

Preschool boys' emotional displays during conflicts with mixed-sex peers were related to individual differences in peer sociometric status and teacher ratings of disruptive behavior. Participants were 60 4- to 5-year old boys from low-income families who were videotaped with a small group of classmates in a Head Start preschool classroom. Conflicts were identified and emotional displays were coded from videotape. Results indicated that conflicts were more negative in emotional tone at the end than at the beginning of the year. Furthermore, children tended to mirror each others' emotional displays at the end but not the beginning of the preschool year. In addition, gleeful taunting, a form of emotional aggression, more strongly predicted negative peer nominations and teacher ratings than anger, suggesting that anger may be a more socially accepted form of emotional expression during conflicts among preschool-age children. Implications and directions for future research and interventions are discussed.
