Prenatal cocaine exposure and infant cognition

The present study examined the relationship of prenatal cocaine exposure to infant information processing in the first year of life.In a prospective, longitudinal study of 177 cocaine-exposed and 175 non-exposed infants, the Fagan Test of Infant Intelligence (FTII) was used to measure attention, visual recognition memory and information processing speed at 6.5 and 12 months of age. Groups were compared over time using mixed linear model analyses.Prenatal cocaine exposure predicted poorer visual recognition memory at 12 months, with exposed infants obtaining lower mean scores and a higher percentage of scores in the risk range. Across exposure groups, information processing speed increased with age, demonstrating a developmental effect. Tobacco and marijuana exposures were related to faster looking times, which did not relate to visual recognition memory.Cognitive deficits and attentional problems noted in prior studies of cocaine-exposed children at later ages may be detectable in infancy.     

Prenatal maternal predictors of cognitive and emotional delays in children of adolescent mothers

The present study examined relationships among prenatal characteristics of 121 adolescent mothers-including cognitive readiness for parenting, intelligence, social support, and personal adjustment-and intellectual-linguistic development, social-emotional functioning, and adaptive behavior in their children at three years of age. Only 28% of the children scored within normal ranges on all three types of outcomes. Intellectual and linguistic delays were predicted best by prenatal measures of maternal Performance IQ and social support from extended family. Socioemotional problems were predicted best by maternal internalizing problems and social support from partner and friends. Adaptive behavior was associated with parenting style. Implications for the early identification of high-risk children--and associated intervention programs--are discussed.     

Family dynamics as predictors of infant disposition

In this longitudinal study of mothers, their families, and their infants, both discriminant and regression analyses showed that prenatal reports of family dynamics predicted infant disposition at 8 months with considerable accuracy. The most important predictive component was organization and consistency within the family unit as well as the dependability of other family members. Possible mechanisms by which family dynamics might affect the infant's developing disposition are discussed.     

Organizational learning and climate as predictors of self-efficacy

This study broadens organizational contextual considerations by examining organizational learning, participation in organizational learning activities and organizational climate as possible predictors of self-efficacy. As schools have been studied as organizations (Handy, 1986, Understanding schools as organizations, Harmondsworth: Penguin; Ostroff, 1993, Organization Behavior and Human Decision Process, 56, 56–90; Ostroff & Schmitt, 1993, Acadamy of Management Journal, 36(6), 1345–1361), this study provides regression results from n = 679 teachers and indicated that organizational climate and organizational learning were significant predictors of teacher self efficacy, controlling for several individual level variables (i.e., participation in organizational learning, personal self-efficacy, and teaching efficacy). Differences between results from the sample of teachers and n = 734 non-teachers (e.g., principals, assistant principals, administrators, counselors, paraprofessional, custodial, food service, and transportation staff) were examined with regard to predictor variables for teaching efficacy. For teachers, both organizational learning and personal self-efficacy were significant predictors of teaching efficacy, whereas for the group of non-teachers, they were not. In both groups, however, participation in organizational learning was a significant predictor, while organizational climate was not (contrary to Taylor & Tashakkori, 1995, Journal of Experimental Education, 63(3), 217–230). Overall, findings provide evidence for extending the research beyond schools and including organizational learning as a potentially important variable in further studying individual outcomes and organizational effectiveness.

Early childhood cognitive development and parental cognitive stimulation: evidence for reciprocal gene-environment transactions

Parenting is traditionally conceptualized as an exogenous environment that affects child development. However, children can also influence the quality of parenting that they receive. Using longitudinal data from 650 identical and fraternal twin pairs, we found that, controlling for cognitive ability at age 2 years, cognitive stimulation by parents (coded from video recorded behaviors during a dyadic task) at 2 years predicted subsequent reading ability at age 4 years. Moreover, controlling for cognitive stimulation at 2 years, children's cognitive ability at 2 years predicted the quality of stimulation received from their parents at 4 years. Genetic and environmental factors differentially contributed to these effects. Parenting influenced subsequent cognitive development through a family-level environmental pathway, whereas children's cognitive ability influenced subsequent parenting through a genetic pathway. These results suggest that genetic influences on cognitive development occur through a transactional process, in which genetic predispositions lead children to evoke cognitively stimulating experiences from their environments.     

Comparing cognitive fusion and cognitive reappraisal as predictors of college student mental health

Transdiagnostic cognitive behavioral interventions target different cognitive processes to promote mental health, including cognitive fusion and cognitive reappraisal. Determining the relative impact of cognitive fusion and reappraisal on a range of student mental health concerns could help interventions target psychopathological cognitive processes more effectively. Therefore, this study examined the longitudinal impact of cognitive fusion and reappraisal on mental health and functioning outcomes. A series of hierarchical regression models tested the effects of cognitive fusion and reappraisal in a sample of college students (n = 339). When controlling for reappraisal and baseline symptoms, fusion predicted distress, depression, generalized anxiety, social anxiety, hostility, academic distress, and student role problems 1 month later. Reappraisal predicted only student role problems longitudinally when controlling for fusion. These results suggest that cognitive fusion is a stronger predictor than reappraisal for a range of student mental health concerns and may be a particularly important target for improving student mental health.     

Evoked prior learning experience and approach to learning as predictors of academic achievement

Background. In separate studies and research from different perspectives, five factors are found to be among those related to higher quality outcomes of student learning (academic achievement). Those factors are higher self‐efficacy, deeper approaches to learning, higher quality teaching, students’ perceptions that their workload is appropriate, and greater learning motivation. University learning improvement strategies have been built on these research results. Aim. To investigate how students’ evoked prior experience, perceptions of their learning environment, and their approaches to learning collectively contribute to academic achievement. This is the first study to investigate motivation and self‐efficacy in the same educational context as conceptions of learning, approaches to learning and perceptions of the learning environment. Sample. Undergraduate students (773) from the full range of disciplines were part of a group of over 2,300 students who volunteered to complete a survey of their learning experience. On completing their degrees 6 and 18 months later, their academic achievement was matched with their learning experience survey data. Method. A 77‐item questionnaire was used to gather students’ self‐report of their evoked prior experience (self‐efficacy, learning motivation, and conceptions of learning), perceptions of learning context (teaching quality and appropriate workload), and approaches to learning (deep and surface). Academic achievement was measured using the English honours degree classification system. Analyses were conducted using correlational and multi‐variable (structural equation modelling) methods. Results. The results from the correlation methods confirmed those found in numerous earlier studies. The results from the multi‐variable analyses indicated that surface approach to learning was the strongest predictor of academic achievement, with self‐efficacy and motivation also found to be directly related. In contrast to the correlation results, a deep approach to learning was not related to academic achievement, and teaching quality and conceptions of learning were only indirectly related to achievement. Conclusions. Research aimed at understanding how students experience their learning environment and how that experience relates to the quality of their learning needs to be conducted using a wider range of variables and more sophisticated analytical methods. In this study of one context, some of the relations found in earlier bivariate studies, and on which learning intervention strategies have been built, are not confirmed when more holistic teaching–learning contexts are analysed using multi‐variable methods.     

Temperamental surgency and emotion regulation as predictors of childhood social competence

The primary aims of the current study were to longitudinally examine the direct relationship between children's temperamental surgency and social behaviors as well as the moderating role of children's emotion regulation. A total of 90 4.5-year-old children participated in a laboratory visit where children's temperamental surgency was rated by experimenters and children's emotion regulation abilities were assessed. The summer before entry into first grade, children's social behaviors with unfamiliar peers were observed in the laboratory and mothers completed a questionnaire about children's social behaviors. Supporting our hypotheses, results revealed that children high in temperamental surgency developed more negative peer behaviors, whereas children low in temperamental surgency were more likely to develop behavioral wariness with peers. Emotion regulatory behaviors were found to moderate the relation between temperamental surgency and aggression, where high-surgent children who showed high levels of social support seeking were less likely to be rated by their mothers as high in aggression. Furthermore, results revealed that low-surgent children who showed high levels of distraction/self-soothing were more likely to show behavioral wariness around unfamiliar peers, whereas high-surgent children who used more distraction/self-soothing behaviors were rated by their mothers as lower in social competence.     

Personality and approaches to learning as predictors of academic achievement

The relationship between personality, approaches to learning, and academic achievement was investigated. Two different undergraduate student samples, totalling 310 students, participated in the study. Results showed the expected significant correlations between the personality factors of openness, neuroticism, and conscientiousness, on the one hand, and deep, surface, and strategic approaches to learning, on the other. A significant negative correlation between surface approach and achievement was observed in sample 1. In sample 2, achievement was positively correlated with neuroticism, openness, and deep approach, and negatively correlated with agreeableness. Path analysis showed that each approach to learning was predicted by multiple personality traits, and that academic achievement was predicted by approaches to learning. A separate analysis showed that the relationship between openness and achievement was mediated by a deep approach to learning. Copyright © 2002 John Wiley & Sons, Ltd.     

Maternal risk factors as predictors of developmental outcome in early childhood

This paper describes the rationale, procedures, and initial validation of an instrument which assesses distal environmental factors thought to negatively influence maternal caregiving ability. A sample of 36 lower class, single, black mothers (ranging in age from 14 to 19 years) of first born, full-term infants were included in an educational intervention program carried out during infants' first 12 months of life. The development of the maternal risk score (MRS) instrument was centered around four areas: maturity of mother, degree of planning of the mother, family support system and level of poverty. Initial, Year 1, Year 2, and Year 3 MRS scores were compared with infant development at one and two years as measured by the Bayley Scales, and at three years with the McCarthy Scales, using Pearson product-moment correlations. The initial MRS correlated negatively with the Bayley Mental Development Index (MDI) at Year 1 and also at Year 2 (N=−.38 and −.40 respectively, both significant at p<.05). The MRS for Year 1 showed significant negative correlations with the two Bayley MDIs: two and three year MRS scores were significantly related to three year McCarthy test scores. This screening instrument, which assesses qualitative aspects of the caretaking environment, appears to be a promising approach for identifying lower class mothers of infants who might be at risk for developmental disabilities.     

Prenatal predictors of maternal and newborn EEG

Ninety-two mothers were recruited at a prenatal ultrasound clinic at which time they were given the CES-D for depression and the State-Trait Anxiety Inventory, and their urines were assayed for cortisol, norepinephrine, epinephrine, dopamine, and serotonin. At the neonatal period the mothers and neonates were assessed on frontal EEG asymmetry. Correlation analyses revealed the following: (1) the mothers’ frontal asymmetry was negatively related to prenatal depression (CES-D) symptoms, negatively related to prenatal norepinephrine levels and positively related to prenatal serotonin levels; (2) the frontal asymmetry of the newborn was positively correlated with the mothers’ frontal asymmetry and negatively correlated with the mothers’ prenatal depression (CES-D) symptoms and negatively correlated with the mothers’ prenatal state anxiety scores. The neonates’ EEG frontal asymmetry was also, like the mother's, negatively related to prenatal maternal norepinephrine and positively related to prenatal maternal serotonin.     

Infant speech perception and cognitive skills as predictors of later vocabulary

Research has identified bivariate correlations between speech perception and cognitive measures gathered during infancy as well as correlations between these individual measures and later language outcomes. However, these correlations have not all been explored together in prospective longitudinal studies. The goal of the current research was to compare how early speech perception and cognitive skills predict later language outcomes using a within-participant design. To achieve this goal, we tested 97 5- to 7-month-olds on two speech perception tasks (stress pattern preference, native vowel discrimination) and two cognitive tasks (visual recognition memory, A-not-B) and later assessed their vocabulary outcomes at 18 and 24 months. Frequentist statistical analyses showed that only native vowel discrimination significantly predicted vocabulary. However, Bayesian analyses suggested that evidence was ambiguous between null and alternative hypotheses for all infant predictors. These results highlight the importance of recognizing and addressing challenges related to infant data collection, interpretation, and replication in the developmental field, a roadblock in our route to understanding the contribution of domain-specific and domain-general skills for language acquisition. Future methodological development and research along similar lines is encouraged to assess individual differences in infant speech perception and cognitive skills and their predictability for language development.     

Infants' persistence and mothers' teaching as predictors of toddlers' cognitive development

This study examined the relative contributions of infants' persistence and mothers' teaching at 6 and 14 months to infants' cognitive development at 14 months in a sample of 65 low-income mother-infant dyads. Infants' persistence was assessed from a videotaped persistence task at 6 months and from the Behavior Record Scale of the Bayley Scales of Infant Development, 2nd ed. (BSID II) at 14 months. Mothers' teaching was assessed from a videotaped teaching interaction at 6 and 14 months using the Nursing Child Assessment Satellite Training (NCAST) teaching scale. Cognitive development at 14 months was based on the Mental Scale, BSID II. Infants' persistence at both ages and mothers' teaching at 6 months each explained unique variance in infants' cognitive status at 14 months. Persistence appears to be a stable quality that can be measured early on, and both infants' early persistence and mothers' teaching are direct pathways to cognitive status at the start of the second year.     

Alternative measures of cognitive complexity as predictors of communication performance

Two studies were conducted to compare the predictive validity of the two of the most popular measures of cognitive complexity: Bieri et al.'s (1966) grid-based measure (elicited and provided versions) and Crockett's (1965) Role Category Questionnaire (RCQ). Two other grid-based measures of construct system quality also were included. Criterion measures included indices of the accommodative, person-centered quality of communication behavior and social reasoning in a variety of contexts.

Results of both studies consistently show Crockett's measure to be a significant predictor of all criterion measures. Bieri et al.'s measures were generally unrelated, although the elicited construct version performed best as a predictor. The two measures of complexity were essentially unrelated in both studies. Implications of the findings for future use of the RCQ and grid-based measures of complexity are discussed. For those interested in the relation of constructs and communication behavior, the RCQ is recommended.     

Low-level lead exposure, executive functioning, and learning in early childhood.

The current paper presents evidence relating low-level lead exposure to impaired executive functioning in young children. Using the Shape School task, we assessed focused attention, attention switching, working memory, and the ability to inhibit automatic responses in a cohort of 170 children. Participants performed the Shape School task at both 48 and 54 months of age; the mean blood lead level was 6.49 microg/dl at 48 months. After controlling for a wide range of sociodemographic, prenatal, and perinatal variables, blood lead level was negatively associated with children's focused attention while performing the tasks, efficiency at naming colors, and inhibition of automatic responding. In addition, children with higher blood lead levels completed fewer phases of the task and knew fewer color and shape names. There was no association between blood lead and performance on the most difficult tasks, those requiring attention switching or the combination of inhibition and switching. Children's IQ scores were strongly associated with blood lead and Shape School performance, and when entered as a covariate, only color knowledge and the number of tasks completed remained significant. Results provide only weak support for impaired executive functioning, but the deficits in color knowledge may indicate a primary sensory deficit or difficulty with forming conditional associations, both implicating disruptions in dopamine system function.     

Cognitive and affective predictors of treatment outcome in cognitive processing therapy and prolonged exposure for posttraumatic stress disorder

This study examined cognitive and affective predictors of treatment dropout and treatment efficacy in Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) for PTSD. Study participants were women with PTSD from a sexual assault who received at least one session of either treatment (n = 145) as part of a randomized clinical trial. Results revealed that younger age, lower intelligence, and less education were associated with higher treatment dropout, whereas higher depression and guilt at pretreatment were associated with greater improvement in PTSD symptomatology. Results by treatment condition indicated that women with higher anger at pretreatment were more likely to dropout of PE and that older women in PE and younger women in CPT had the best overall outcomes. These findings have implications for efforts to enhance treatment efficacy and retention in CBT treatment protocols.     

Prenatal exposure to methadone and buprenorphine: A review of the potential effects on cognitive development

The amount of opioid users receiving opioid maintenance therapy has increased significantly over the last few years. As a result, an increasing number of children are prenatally exposed to long-lasting opioids such as methadone and buprenorphine. This article reviews the literature on the cognitive development of children born to mothers in opioid maintenance therapy. Topics discussed are the effects of prenatal exposure on prematurity, somatic growth, brain volume, myelination, and the endocrine and neurotransmitter system. Social-environmental factors, including parental functioning, as well as genetic factors are also described. Areas requiring further research are identified.
