In this study, the authors examined the extent to which children’s self-regulation upon kindergarten entrance and classroom quality in kindergarten contributed to children’s adaptive classroom behavior. Children’s self-regulation was assessed using a direct assessment upon entrance into kindergarten. Classroom quality was measured on the basis of multiple classroom observations during the kindergarten year. Children’s adaptive classroom behavior in kindergarten was assessed through teacher report and classroom observations: Teachers rated children’s cognitive and behavioral self-control and work habits during the spring of the kindergarten year; observers rated children’s engagement and measured off-task behavior at 2-month intervals from November to May. Hierarchical linear models revealed that children’s self-regulation upon school entry in a direct assessment related to teachers’ report of behavioral self-control, cognitive self-control, and work habits in the spring of the kindergarten year. Classroom quality, particularly teachers’ effective classroom management, was linked to children’s greater behavioral and cognitive self-control, children’s higher behavioral engagement, and less time spent off-task in the classroom. Classroom quality did not moderate the relation between children’s self-regulation upon school entry and children’s adaptive classroom behaviors in kindergarten. The discussion considers the implications of classroom management for supporting children’s early development of behavioral skills that are important in school settings.

Reports an error in "Affect dynamics, affective forecasting, and aging" by Lisbeth Nielsen, Brian Knutson and Laura L. Carstensen (Emotion, 2008[Jun], Vol 8[3], 318-330). The first author of the article was listed as being affiliated with both the National Institute on Aging and the Department of Psychology, Stanford University. Dr. Nielsen would like to clarify that the research for this article was conducted while she was a postdoctoral fellow at Stanford University; her current affiliation is only with the National Institute on Aging. The copyright notice should also have been listed as “In the Public Domain.” (The following abstract of the original article appeared in record 2008-06717-002.) [Correction Notice: The same erratum for this article was reported in Vol 8(5) of Emotion (see record 2008-13989-013).] Affective forecasting, experienced affect, and recalled affect were compared in younger and older adults during a task in which participants worked to win and avoid losing small monetary sums. Dynamic changes in affect were measured along valence and arousal dimensions, with probes during both anticipatory and consummatory task phases. Older and younger adults displayed distinct patterns of affect dynamics. Younger adults reported increased negative arousal during loss anticipation and positive arousal during gain anticipation. In contrast, older adults reported increased positive arousal during gain anticipation but showed no increase in negative arousal on trials involving loss anticipation. Additionally, younger adults reported large increases in valence after avoiding an anticipated loss, but older adults did not. Younger, but not older, adults exhibited forecasting errors on the arousal dimension, underestimating increases in arousal during anticipation of gains and losses and overestimating increases in arousal in response to gain outcomes. Overall, the findings are consistent with a growing literature suggesting that older people experience less negative emotion than their younger counterparts and further suggest that they may better predict dynamic changes in affect.

Objective: Posttraumatic stress disorder (PTSD) reflects a prolonged stress reaction and dysregulation of the stress response system and is hypothesized to increase risk of developing coronary heart disease (CHD). No study has tested this hypothesis in women even though PTSD is more prevalent among women than men. This study aims to examine whether higher levels of PTSD symptoms are associated with increased risk of incident CHD among women. Design: A prospective study using data from women participating in the Baltimore cohort of the Epidemiologic Catchment Area study (n = 1059). Past year trauma and associated PTSD symptoms were assessed using the NIMH Diagnostic Interview Schedule. Main Outcome Measures: Incident CHD occurring during the 14-year follow-up through 1996. Results: Women with five or more symptoms were at over three times the risk of incident CHD compared with those with no symptoms (age-adjusted OR = 3.21, 95% CI: 1.29-7.98). Findings were maintained after controlling for standard coronary risk factors as well as depression or trait anxiety. Conclusion: PTSD symptoms may have damaging effects on physical health for civilian community-dwelling women, with high levels of PTSD symptoms associated with increased risk of CHD-related morbidity and mortality.

Expository Text Comprehension in the Primary Grade Classroom.   总被引:1,自引:0,他引:1  
This study investigates the effectiveness of an instructional program designed to teach 2nd graders how to comprehend compare-contrast expository text. Along with introducing new content (animal classification), the program emphasizes text structure via clue words, a sequence of questions, and a graphic organizer, and via the close analysis of specially constructed exemplar paragraphs. The authors compared the program with (a) more traditional instruction that focused only on the new content and (b) a no instruction control; 128 7- and 8-year-olds participated. Classroom teachers provided the instruction. The program improved students' ability to comprehend compare-contrast texts. Students were able to demonstrate transfer to uninstructed compare-contrast texts though not to text structures other than compare-contrast. Moreover, the text structure instruction did not detract from their ability to learn new content. The results provide evidence, heretofore lacking, that explicit instruction in comprehension is feasible and effective as early as the 2nd grade.

This study examined associations of temperament at ages 6 to 12 with body-mass index (BMI) and waist circumference (WC) at ages 24 to 30 years. The participants were 619 men and women derived from the population-based Cardiovascular Risk in Young Finns Study. Temperament was operationalized as (negative) emotionality, sociability, and activity. High emotionality predicted increased BMI, independently of WC, and independently of childhood and adulthood risk factors for adult obesity. None of the temperament dimensions had any associations with WC after controlling for BMI. The findings suggest that temperamental difficulty in childhood may be a useful risk indicator for general body mass in adulthood, and the mechanisms relating temperament with body mass should be further explored.

Media reports frequently depict older adults as victims of deception. The public perceives these stories as particularly salient because older adults are seen as fragile victims taken advantage of because of trusting behaviors. This developmental investigation of deception detection examines older and younger adults interacting in 2 contexts, prison and the "free world," to discover whether older adults are vulnerable to deception. Younger prisoners were found to be lie biased. Older adults were better able to discriminate lies than younger adults, and this effect was localized primarily to older female adults. Findings indicate that discriminability strongly increases from younger to older age for women, whereas men do not show an improvement, as age increases, in making decisions about statement veracity.

Working memory mediates the short-term maintenance of information. Virtually all empirical research on working memory involves investigations of working memory for verbal and visual information. Whereas aging is typically associated with a deficit in working memory for these types of information, recent findings suggestive of relatively well-preserved long-term memory for emotional information in older adults raise questions about working memory for emotional material. This study examined age differences in working memory for emotional versus visual information. Findings demonstrate that, despite an age-related deficit for the latter, working memory for emotion was unimpaired. Further, older adults exhibited superior performance on positive relative to negative emotion trials, whereas their younger counterparts exhibited the opposite pattern.

Rural psychologists are frontline primary behavioral health care providers for nearly 60 million Americans, but they face limited access to peer consultation and continuing education. This article describes a program that matched 70 rehabilitation inpatients who had new brain injury with rural clinicians from patients' home communities. Neuropsychologists provided one-on-one training for clinicians through telehealth video teleconferencing. Clinicians showed gains in brain injury knowledge, and clients rated trained providers higher than untrained providers. Families seeking brain injury services can connect with these trained rural providers through a Web site, which receives more than 800 hits per month. Telehealth offers potential for rural clinicians to receive support, reduce professional isolation, gain working knowledge of specialty conditions, and deliver high-quality services for their rural clients.

The current study used ecological momentary assessment to test several tenets of the reserve capacity model (L.C. Gallo & K. A. Matthews, 2003). Women (N = 108) with varying socioeconomic status (SES) monitored positive and negative psychosocial experiences and emotions across 2 days. Measures of intrapsychic and social resources were aggregated to represent the reserve capacity available to manage stress. Lower SES was associated with less perceived control and positive affect and more social strain. Control and strain contributed to the association between SES and positive affect. Lower SES elicited greater positive but not negative emotional reactivity to psychosocial experiences. Women with low SES had fewer resources relative to those with higher SES, and resources contributed to the association between SES and daily experiences.

The use of fiber-reinforced polymer (FRP) composites for strengthening and/or rehabilitation of concrete structures is gaining increasing popularity in the civil engineering community. One of the most attractive applications of FRP materials is their use as confining devices for concrete columns, which may result in remarkable increases of strength and ductility as indicated by numerous published experimental results. Despite a large research effort, a proper analytical tool to predict the behavior of FRP-confined concrete has not yet been established. Most of the available models are empirical in nature and have been calibrated against their own sets of experimental data. On the other hand, the experimental results available in the literature encompass a wide range of values of the significant variables. The objective of this work is a systematic assessment of the performance of the existing models on confinement of concrete columns with FRP materials. The study is conducted in the following steps: the experimental data on confinement of concrete cylinders with FRP available in the technical literature are classified according to the values of the significant variables; the existing empirical and analytical models are reviewed, pointing out their distinct features; the whole set of available experimental results is compared with the whole set of analytical models; and strengths and weaknesses of the various models are analyzed. Finally, a new equation is proposed to evaluate the axial strain at peak stress of FRP-confined concrete cylinders.  相似文献
