Neurocognitive Correlates of Type 1 Diabetes Mellitus in Childhood

Type 1 Diabetes Mellitus (T1DM) is one of the most prevalent chronic health conditions in children under the age of 18 years. Complications of the disease include hypo- and hyperglycemia, which can have an impact on children’s performance in assessment situations, in the clinic, and in school. Because there is no cure for this disease, there is a need to understand the cognitive deficits associated with some of its complications, as this knowledge will impact on the choice of treatment regimens as well as educational interventions. This paper provides a comprehensive review of the relevant literature on the neurocognitive outcome of T1DM. In particular, disease- and treatment-related variables that are associated with poor performance on cognitive domains will be reviewed. Specifically, age of onset, duration, pubertal effects, and presence of hypoglycemia or hyperglycemia will be examined. These findings are not without controversy, and limitations to conclusions will also be presented. Where relevant, recommendations for future research directions will be provided.     

Sociometric Stability and the Behavioral Correlates of Peer Acceptance in Early Childhood

The author presents findings from an Australian study examining the behavioral correlates and stability of social status among preschool-aged children. Using sociometric assessment, the author determined the social status of an initial sample of 187 preschool-aged children (94 boys, 93 girls; M age = 62.4 months, SD age = 4.22 months). The author observed children (N = 70) who were classified as rejected, neglected, or popular. For a total of 25 min during a 3-month period, the author observed children engaging in free play in their preschool centers. Results indicate that children classified as popular were more likely to engage in cooperative play, engage in ongoing connected conversation, and display positive affect, compared with those classified as rejected or neglected. Popular children were less likely than rejected children or neglected children to engage in parallel play, onlooker behavior, or alone-directed behavior. To test for stability and change, the author repeated sociometric interviews 6 months after initial sociometric classification. Results indicate that preschool-aged children's social status classifications showed a moderate to high rate of stability for those children classified as popular, rejected, or neglected.     

Multilevel Correlates of Childhood Physical Aggression and Prosocial Behavior

The study identified independent individual, family, and neighborhood correlates of children's physical aggression and prosocial behavior. Participants were 2,745 2–11-year olds nested in 1,982 families, which were themselves nested in 96 Canadian neighborhoods. Hierarchical linear modeling showed that the total variation explained by the three-level model was 28.03% for physical aggression and 17.57% for prosocial behavior. For both childhood behaviors, approximately 66% of this explained variance was between individuals and up to 30% was between families. The smallest amount of observed variation was between neighborhoods. Significant individual-level predictors common to both childhood behaviors were child's sex and maternal hostility toward the target child. Specifically, boys had more mother-reported physical aggression and less prosocial behavior. Children who experienced greater-than-average maternal hostility (compared to siblings) were more physically aggressive and less prosocial. At the family level, significant common predictors were mother depressed mood and punitive parenting. Children had higher levels of physical aggression and lower levels of prosocial behavior in families where mothers had greater depressed mood and used more punitive parenting practices. At the neighborhood level, greater perceived problems and lower poverty level were associated with higher levels of physical aggression. Results are discussed with reference to past and future studies of multilevel effects on children's socialization.     

Correlates of Maternal and Paternal Adjustment to Chronic Childhood Disease

This study investigated the correlates of psychosocial adjustment in mothers and fathers of children with chronic disease. Participants were 20 mothers and 15 fathers of children with cystic fibrosis, 11 mothers and 9 fathers of children with muscular dystrophy, 18 mothers and 9 fathers of children with asthma, 13 mothers and 8 fathers of children with Type 1 diabetes and 19 mothers and 11 fathers of healthy children. Questionnaires relating to the variables of interest were used. Poorer levels of adjustment were associated with lower levels of social support and family cohesion for mothers and coping by understanding the child’s medical situation, more family life events and lower family cohesion for fathers. These findings suggest that the correlates associated with maternal and paternal psychological adjustment to chronic childhood disease differ. These differences are important to consider when providing care to children with chronic disease and their families.     

Mother-Child Conflict Interaction in the Toddler Years: Behavior Patterns and Correlates

We examined mother-child (M-C) conflict behavior during the toddler years. The nature of M-C conflict behaviors, whether conflict behavior differed by context, and factors that were associated with conflict interactions were examined. We used data collected as part of the National Evaluation of the Healthy Steps for Young Children Program. 378 M-C dyads participated in this study. Videotaped observational data at 16–18 months were used to code conflict behaviors using an event recording method. Results showed that M-C conflict were more likely to be initiated by the mothers and that conflict interactions were influenced by context of interaction, family, maternal, and child temperamental factors. In this study, we provide a foundation for understanding parent-child conflict interaction prior to age two.     

The Development and Correlates of Academic Interests from Childhood through Adolescence

Study goals were to assess: (1) the development of academic interests from middle childhood through late adolescence, (2) the degree to which junior high and high school transitions, parents' educational expectations, interests, and education, were related to changes in academic interests, and (3) the longitudinal links between youth's academic interests and school grades. Participants were mothers, fathers, and two siblings from 201, White, working and middle class families who were interviewed in their homes on up to 9 annual occasions. Multi-level model analyses revealed overall declines in youth's interests over time, with boys showing more rapid decline than girls. Mothers' educational expectations were positively related to youth's interests, and youth's interests declined less when fathers had more education. The transition to junior high, but not high school, was linked to decline in interests, but this was buffered by mothers' academic interests. Declines in youth's academic interests were linked to declines in school grades.     

Theory of Mind Understanding and Conversational Patterns in Middle Childhood

The author investigated the longitudinal relations between theory of mind (ToM) understanding and perceptions of self and social conversations in 17 school-aged children (12 girls, 5 boys, age 8–12 years). ToM was assessed at Time 1 (T1; M age = 8 years 5 months, SD = 8.7 months, and perceptions of self and conversational experiences assessed two years later at Time 2 (T2; M age = 10 years 4 months, SD = 7.9 months. Most importantly, longitudinal findings showed that children who scored relatively high on ToM at T1 reported relatively lower perceptions of self-worth and higher number of mental states verbs in their perceptions of peer and family conversations at T2. Significant negative longitudinal associations were found between children's number of siblings and their perceptions of self-worth (T1) and number of cognitive terms in their perceptions of peer and family conversations (T2). Frequency analysis suggested that girls’ perceptions of conversations referred to more social and psychological aspects of self and relationships, whereas boys focused mainly on physical activities. Most children were more likely to prefer listening to talking during social conversations. The majority of children reported feelings of mixed or ambiguous emotions during experiences of silence. Implications for socioemotional and cognitive development in early adolescents are discussed.     

The Structure of Internalizing Disorders in Middle Childhood and Evidence for Personality Correlates

The current multi-method multi-informant investigation compared the fit of three competing models of internalizing problems in middle childhood: (1) a unitary factor model, (2) a two-factor model corresponding to the DSM-IV Anxiety/Depression distinction, and (3) a two-factor model corresponding to the Fear/Distress distinction observed in structural studies of adult psychopathology (Krueger Archives of General Psychiatry, 56:921-926, 1999); Slade and Watson Psychological Medicine, 36:1593-1600, 2006). In total, 346 youths (mean age = 9.51, SD = .78) and their adult caregivers (344 mothers, 227 fathers) reported on childhood internalizing symptoms and personality traits. Confirmatory factor analyses revealed adequate to good fit indices for all three models, although the unitary factor model provided the most parsimonious summary of the data. Although the structural analyses suggested that internalizing symptom subfactors were not clearly differentiated in middle childhood, hierarchical regression analyses revealed that personality dimensions uniquely predicted the Anxiety/Fear and Depression/Distress disorders. These results suggest that personality correlates differentiate childhood psychopathology structure before it is manifest at the symptom level.     

The Temporal Consistency of Personality Effects: Evidence from the British Household Panel Survey

Personality traits have been posited to function as stable influences on political attitudes and behavior. Although personality traits themselves exhibit high levels of temporal stability, it is not yet known whether the effects of these traits are marked by comparable temporal consistency. To address this question, this research note examines data from Wave 13 (2003–2004), Wave 15 (2005–2006) and Wave 17 (2007–2008) of the British Household Panel Survey (BHPS). Twenty‐seven behavioral and 14 attitudinal dependent variables are studied. Consistency of effects is gauged via a series of multilevel models in which personality effects are permitted to vary by year. High levels of temporal consistency are observed for personality traits as represented by the Big Five framework.     

Longitudinal Development of Memory for Temporal Order in Early to Middle Childhood

Abstract

Existing studies examining the development of temporal order memory show that although young children perform above chance on some tasks assessing temporal order memory, there are significant age-related differences across childhood. Yet, the trajectory of children’s ability to retrieve temporal order remains unclear as existing conclusions are drawn from cross-sectional studies. The present study utilized an accelerated longitudinal design in order to characterize the developmental trajectory of temporal order memory in a sample of 200 healthy 4- to 8-year-old children. Specifically, two tasks commonly used in the literature were tested longitudinally: a primacy judgment task and an ordering task. Results revealed that, even after controlling for differences in IQ, linearly increasing trajectories characterized age-related change in performance for both tasks; however, change appeared greater for the temporal ordering task. Further, performance on the two tasks was positively related, suggesting shared underlying mechanisms. These findings provide a more thorough understanding of temporal order memory in early to middle childhood by characterizing the developmental trajectories of two commonly used tasks and have important implications for our understanding of children’s developing memory more broadly.     

Object Relations and Ego Development: Comparison and Correlates In Middle Childhood

The significance of ego development and object relations for adaptation and adjustment in middle childhood was examined in a study of 92 nine- to twelve-year-old children. Subjects completed the Sentence Completion Test (SCT) and the Blatt Object Relations Scale (BORS) in individual sessions. BORS ratings were factor analyzed and a predominant factor of parental nurturance emerged. This factor was positively related to children's self-reported perceptions of parental involvement and autonomy support but was unrelated to the SCT. SCT findings revealed an expected pattern for middle childhood with the preponderance of children falling into impulsive, self-protective, and conformist stages of ego development. Both the SCT and BORS were examined in relation to aspects of children's cognitive and social functioning, assessed via teacher ratings, peer sociometrics, self-evaluations, and academic achievement records. Results showed that the SCT was primarily related to cognitive complexity variables, while the object relations measure was associated with both peer and self-evaluations. These nonoverlapping relations with varied child outcomes are discussed both in terms of methodological limitations and theoretical significance.     

Investigating Correlates of Self-Regulation in Early Childhood with a Representative Sample of English-Speaking American Families

Children who possess less self-regulatory skill are at a disadvantage when compared to children who demonstrate greater skill at regulating their emotions, cognitions and behavior. Children with these regulatory deficits have difficulty connecting with peers, generating relationships with teachers, negotiating their social world, and succeeding academically. By understanding the correlates of self-regulatory abilities, interventions can be developed to ensure that children at-risk for poor self-regulation receive the support necessary to enhance their regulatory skills. Using data from a nationally representative survey of English-speaking American parents with children between the ages of two and eight (n = 1,141), we evaluated a host of demographic and parenting variables to isolate the correlates of self-regulation. Older children were found to have fewer regulatory problems than younger children while children from low-income homes and male children were found to have greater problems with self-regulation. Minority status, household composition (single vs multi-parent), and parental education were not significant correlates of self-regulation. Findings also illustrate the powerful relationship between parenting style and self-regulation. Parents who rely on nurturing parenting practices that reinforce the child’s sense of autonomy while still maintaining a consistent parenting presence (i.e., authoritative parenting) have children who demonstrate stronger self-regulatory skills. Parents who exert an excess of parental control (i.e., authoritarian parents) have children with weaker self-regulatory skills. And lastly, parents who have notable absence of control (i.e., permissive parents) are more likely to have children with considerable regulatory deficits. Results offer implications for both practitioners and scholars.     

A New Tactile Illusion: Temporal Limits on the Processing of Spatiotemporal Patterns

A novel illusion was observed when 12 tactile point-stimulators arranged in a circle were sequentially activated so that each quadrant was first traced in a clockwise manner, then counterclockwise, and again in a clockwise manner, after which the next quadrant was similarly traced. Under certain temporal conditions this stimulus pattern was experienced as a point moving through an overall circular path but looping inwardly about once per quadrant. The effects of variations in rate of presentation of such stimuli were investigated by having subjects make drawings of their perceptual experiences. Three skin surfaces were used (palm, fingers, and forearm), and all produced similar results except for lower confidence and reliability of drawings made from forearm stimulation. Pattern presentation rate, however, had a consistent and powerful effect, with the looping illusion most frequently observed at rates around 25 pattern points per s and with different perceptual organizations dominating as rates departed widely from this optimum. The illusory perceptual organizations were interpreted as compromises between past and present stimulation necessitated by the relative slowness of tactile processing of spatio-temporal patterns.     

Temporal integration and segregation of brief visual stimuli: Patterns of correlation in time

Two brief sequential displays separated by a brief interstimulus interval (ISI) are often perceived as a temporally integrated unitary configuration. The probability of temporal integration can be decreased by increasing the ISI or (counterintuitively) by increasing stimulus duration. We tested three hypotheses of the relative contributions of stimulus duration and ISI to the breakdown of temporal integration (the storage, processing, and temporal correlation hypotheses). In the first of two experiments, stimulus duration and ISI were varied factorially, and estimates of temporal integration were obtained with a form-part integration task. The second experiment was a replication of the first at two levels of stimulus intensity. The outcomes were inconsistent with the storage and processing options, but confirmed predictions from the temporal correlation hypothesis. Whether two sequential stimuli are perceived as temporally integrated or disjoint depends not on the availability of visible persistence, but on the emergence of a neural code that is based on the temporal correlation between the two visual responses.     

Gender Differences in Speech Temporal Patterns Detected Using Lagged Co-occurrence Text-Analysis of Personal Narratives

This paper describes a novel methodology for the detection of speech patterns. Lagged co-occurrence analysis (LCA) utilizes the likelihood that a target word will be uttered in a certain position after a trigger word. Using this methodology, it is possible to uncover a statistically significant repetitive temporal patterns of word use, compared to a random choice of words. To demonstrate this new tool on autobiographical narratives, 200 subjects related each a 5-min story, and these stories were transcribed and subjected to LCA, using software written by the author. This study focuses on establishing the usefulness of LCA in psychological research by examining its associations with gender. The application of LCA to the corpus of personal narratives revealed significant differences in the temporal patterns of using the word “I” between male and female speakers. This finding is particularly demonstrative of the potential for studying speech temporal patterns using LCA, as men and women tend to utter the pronoun “I” in comparable frequencies. Specifically, LCA of the personal narratives showed that, on average, men tended to have shorter interval between their use of the pronoun, while women speak longer between two subsequent utterances of the pronoun. The results of this study are discussed in light of psycholinguistic factors governing male and female speech communities.     

Division of Labor Among Lesbian and Heterosexual Parenting Couples: Correlates of Specialized Versus Shared Patterns

One of the central tasks that couples face in coparenting is the division of labor. In this study, we explored division of family labor among lesbian and heterosexual couples who were parenting 4 to 6 year-old children. Sixty-six families, half headed by lesbian couples and half headed by heterosexual couples, participated in the study. Measures of parental attitudes, resources, demographics, and division of labor were collected. As expected, lesbian couples were more likely to divide paid and unpaid labor evenly, whereas heterosexual couples were more likely to show specialized patterns, with husbands investing more time in paid employment and wives devoting more time to unpaid family work. Structural variables (e.g., husband's hours in paid employment) were the best predictors of division of labor among heterosexual couples. Among lesbian couples, however, ideological variables (e.g., ideas about ideal divisions of labor) were the better predictors. Discrepancies in occupational prestige were greater among heterosexual than among lesbian couples. Discussion centers on the ways in which gender and sexual orientation may relate to couples' decisions about division of labor.
