Patterns of Silent Reading Rate and Comprehension as a Function of Developmental Status,Genre, and Text Position

This study examined how comprehension-based silent reading rate (CBSRR) is affected by grade, genre, and text position. Second and fourth graders read 2 grade-specific passages (one narrative, one informational) in 4 sections, each followed by 4 comprehension questions. Analyses of rate with a criterion level of comprehension showed higher performances on informational than narrative texts and better performances as students moved through sections of a text. Percentages of students attaining CBSRR decreased across the four sections of both genres and at both grade levels. Implications of findings are discussed and question are raised about text complexity and silent reading patterns.     

Cognitive and temperamental vulnerability to depression: Longitudinal associations with regional cortical activity

Posterior cortical activity may be related to individual differences in temperamental emotionality, especially traits implicated in depression vulnerability. We previously reported that electroencephalographic (EEG) indices of cortical activity in posterior regions were associated with temperamental positive emotionality (PE) in early childhood. This project examined whether EEG indices of regional cortical activity, assessed at age 5–6, were associated with child temperament and cognitive vulnerability to depression, assessed at age 7. Asymmetry in posterior cortical activity measured at age 5–6 was associated with PE at follow-up at age 7, and with greater helplessness during a standardised laboratory task simulating a mild interpersonal rejection. Findings provide further support for the notion that low PE and depression are associated with similar patterns of cortical activity. Furthermore, these patterns of activity may have observable behavioural and cognitive correlates that are meaningfully linked to the phenomenology of depression.     

The role of parenting and dopamine D4 receptor gene polymorphisms in children's inhibitory control

Temperamental effortful control has important implications for children's development. Although genetic factors and parenting may influence effortful control, few studies have examined interplay between the two in predicting its development. The current study investigated associations between parenting and a facet of children's effortful control, inhibitory control (IC), and whether these associations were moderated by whether children had a 7‐repeat variant of the DRD4 exon III VNTR. A community sample of 409 3‐year‐olds completed behavioural tasks to assess IC, and observational measures of parenting were also collected. Negative parenting was associated with lower child IC. The association between children's IC and positive parenting was moderated by children's DRD4 7‐repeat status, such that children with at least one 7‐repeat allele displayed lower IC than children without this allele when positive parenting was lower. These effects appeared to be primarily influenced by parent support and engagement. Results extend recent findings suggesting that some genetic polymorphisms may increase vulnerability to contextual influences.     

Understanding the School Experience of African-American Homeless Children

Homelessness is a devastating problem that breeds far-reaching negative impacts on all aspects of children's lives, including their school experience. Fifteen homeless, African-American children in grades 3 through 6 were interviewed about their experiences at school, as well as their future educational and career aspirations. Findings of a grounded theory analysis reveal that these children struggled to envision a safe future through seeking predictability, personal connections, and academic achievement, and provide insight for interventions. The study examines the ways the children constructed meaning out of their school experience, understood their transitions, and set life goals. By understanding the ways these youth experience their school experience, psychologists, counselors, and educators can be better equipped to serve their needs by providing support services that support their development, by developing educational practices that shape realistic educational goals, and by moving toward systemic change through collaborating with administrators and other stakeholders.     

Social power facilitates the effect of prosocial orientation on empathic accuracy

Power increases the tendency to behave in a goal-congruent fashion. Guided by this theoretical notion, we hypothesized that elevated power would strengthen the positive association between prosocial orientation and empathic accuracy. In 3 studies with university and adult samples, prosocial orientation was more strongly associated with empathic accuracy when distinct forms of power were high than when power was low. In Study 1, a physiological indicator of prosocial orientation, respiratory sinus arrhythmia, exhibited a stronger positive association with empathic accuracy in a face-to-face interaction among dispositionally high-power individuals. In Study 2, experimentally induced prosocial orientation increased the ability to accurately judge the emotions of a stranger but only for individuals induced to feel powerful. In Study 3, a trait measure of prosocial orientation was more strongly related to scores on a standard test of empathic accuracy among employees who occupied high-power positions within an organization. Study 3 further showed a mediated relationship between prosocial orientation and career satisfaction through empathic accuracy among employees in high-power positions but not among employees in lower power positions. Discussion concentrates upon the implications of these findings for studies of prosociality, power, and social behavior.     

The role of brain-derived neurotrophic factor genotype, parental depression, and relationship discord in predicting early-emerging negative emotionality

The brain-derived neurotrophic factor (BDNF) gene is a plausible candidate for early-emerging negative emotionality (NE), and evidence suggests that the effects of this gene may be especially salient in the context of familial risk for child maladjustment. We therefore examined whether the single-nucleotide polymorphism producing a valine-to-methionine substitution at codon 66 (val66met) of the BDNF gene was associated with childhood NE, in the context of parental depression and relationship discord. A sample of 413 three-year-old children was assessed for NE using standardized laboratory measures. The children's parents completed clinical interviews as well as a measure of marital satisfaction. Children with at least one BDNF methionine (met) allele exhibited elevated NE when a parent had a history of depressive disorder or when relationship discord was reported by a parent. In contrast, this allele was associated with especially low NE when parental depression was absent and when the parental relationship was not discordant. Our findings suggest that the BDNF met allele confers increased child sensitivity to both positive and negative familial influences.     

Relation of dispositional optimism with burnout among athletes

Optimism is important in enhancing human psychological and physical well-being; however, the association of optimism with burnout has received little attention in sport psychology. This study recruited 139 young volleyball players (M = 16.3 yr., SD = 0.8) to examine this relation. Athletes completed the Chinese version of the Life Orientation Test at Time 1 and 4 mo. later (Time 2). The Chinese version of the Athlete Burnout Questionnaire was also administered. Analysis showed scores on optimism were negatively related to athletes' burnout scores.     

Relations between uniform connectedness, luminance, and shape similarity as perceptual organizational cues in infancy

Although several studies have examined infants' sensitivity to perceptual organizational cues, few have examined the functional relations among these cues. We examined how uniform connectedness (UC) functions in relation to shape and luminance similarity. UC has been characterized as the entry-level mechanism of perceptual organization and would therefore be predicted to be more salient than the other two cues. We found that UC was more salient than shape similarity organization was, to the point that 6- to 7-month-old infants failed to even organize on the basis of shape in the presence of UC. Luminance similarity, however, was more salient than UC, even though UC was detected by infants in the presence of luminance cues. We conclude that UC is not necessarily the most salient mechanism of perceptual organization in infancy. Moreover, the luminance-UC-shape salience hierarchy exhibited by 6- to 7-month-olds in the present study is consistent with the order of development of sensitivity to these organizational cues.     

Stutterers' voice initiation times during conditions of novel stimulation

The present experiment examined stutterers' voice initiation times (VITs) during conditions of novel stimulation. The experimenters were interested in determining how VITs varied as a function of pacing and masking. Stutterers were examined in control, pacing, and masking conditions. The results indicated that: (1) stutterers significantly improved their VITs in the pacing condition as compared with the control condition (p = 0.005), (2) stutterers had significantly faster VITs in the pacing condition as compared with the masking condition (p = 0.005), and (3) stutterers improved VITs in the masking condition as compared with the control condition (p = 0.075). These results are discussed in terms of the facilatory nature of novel stimulation in modifying speech-system functioning.     

Neuroticism, coping strategies, and negative well-being among caregivers.

Neuroticism was incorporated into a model for predicting the well-being of family caregivers. Using data from 596 women with an adult child with a chronic disability, the model hypothesizes direct effects of neuroticism on a caregiver's perceptions of the stressor, on her wishful-escapism and problem-focused coping, and on psychological well-being. Results indicate that neuroticism exerts direct and indirect effects on negative well-being. Results also indicate that stressors have direct effects on both wishful-escapism coping and problem-focused coping. Burden had direct effects on negative psychological well-being. Diagnosis influences the model by having direct effects on stressors and wishful-escapism coping but not on problem-focused coping or burden. Inclusion of individual level variables, such as neuroticism, results in a substantial amount of explained variance in negative well-being.
