Vigilance and cardiovascular reactivity to subsequent stressors in men: A preliminary study.

Understanding moderators of acute responses to stress has implications for a variety of outcomes in health psychology. The present study investigated the role of sustained search for potential threat in acute cardiovascular stress responses. As a means of manipulating vigilance for threat in the laboratory, male participants (N?=?30) were randomly assigned to search, on a computer screen, for statements that were negative, positive, or occurring at known intervals. Relative to participants in the other search conditions, participants in the negative search condition had significantly higher systolic and diastolic blood pressure responses during subsequent stressors. These results encourage a closer look at the effects of vigilance for threat. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gender and young children's expectations for performance in arithmetic.

Tracked the progress of approximately 1,100 children from the beginning of 1st grade to the end of 3rd grade. Ss included Whites at a suburban school and Blacks and Whites whose background was urban and lower class. Ss', their mothers', and their peers' expectations for their grades in reading, arithmetic, and conduct were assessed each semester. Ss' actual grades and achievement test scores were also obtained. Data suggest that the schooling experience in 1st, 2nd, and 3rd grades differed according to gender, even though the 2 sexes sat together in the same classrooms. Although boys' arithmetic marks and/or general aptitude did not exceed girls', data indicate that boys developed higher expectations for their own performance in arithmetic than did girls, apparently in response to differential expectations held by their parents.

Cardiac autonomic reactivity and recovery in predicting carotid atherosclerosis: The cardiovascular risk in young finns study.

The present study examined the association of cardiac autonomic task-induced reactivity and recovery to preclinical atherosclerosis. Thirty-three men and 33 women aged 24-39 years participated in the ongoing epidemiological Cardiovascular Risk in Young Finns study. The authors measured heart rate (HR), respiratory sinus arrhythmia (RSA), and preejection period (PEP) during the mental arithmetic and speech tasks in 1999. Carotid atherosclerosis was assessed by measuring the thickness of the common carotid artery intima-media complex (IMT) with ultrasound in 2001. Higher HR, RSA, and PEP reactivity were associated with lower IMT values even after adjusting for cardiovascular risk factors (lipid levels, obesity, and blood pressure). In addition, better HR recovery after the mental arithmetic task was associated with lower IMT values, and this association persisted after all adjustments. Thus, higher task-induced cardiac autonomic reactivity and better HR recovery were related to less preclinical atherosclerosis. The authors concluded that cardiac pattern of reactivity and quick recovery may be associated with better cardiovascular health, and therefore all reactivity occurring in challenging situations should not automatically be considered as potentially pathological.

Socialization of children's vicarious emotional responding and prosocial behavior: Relations with mothers' perceptions of children's emotional reactivity.

Examined mother–child emotion-related interactions and how these interactions related to mothers' perceptions of children's emotional reactivity. Mothers of 49 kindergartners and 54 2nd graders told their children 2 stories about distressed others. Children's emotional, physiological, and prosocial responses were also obtained. Mothers rated children's tendencies to become emotional when exposed to distressed others. For kindergartners, mothers' perceptions of children's emotional reactivity were positively related to her use of positive facial expressions. Mothers' perceptions of 2nd graders' emotional reactivity were inversely related to maternal responsiveness. These findings suggest that mothers may "adjust" their interactions with their children based on their perceptions of children's emotional tendencies.

Menstrual cycle and premenstrual syndrome: Modifiers of cardiovascular reactivity in women.

15 women prospectively diagnosed with premenstrual syndrome (PMS) and 15 non-PMS women were each tested twice for cardiovascular stress reactivity and behavioral performance, once during the follicular phase and once during the luteal phase of their cycle. Although blood pressure and heart rate responses to stress did not differ across the menstrual cycle in either group of women, for the non-PMS women, differences in hemodynamic responses were observed across the 2 phases. The luteal phase was associated with greater stroke volume responses and lesser vascular tone. For the PMS women, none of their cardiovascular measures differed across their cycle. Instead, these women showed significantly attenuated blood pressure and heart rate responses compared with non-PMS women, irrespective of cycle phase.

Black children's use of nonstandard grammar: Two years later.

A Berko-type task requiring Ss to derive the present, plural, possessive, and time extension forms of nonsense syllables was administered to 115 Black and White 2nd graders and readministered to a subsample of these same children upon their reaching the 4th grade. At both 2nd- and 4th-grade levels, White Ss supplied significantly more standard English responses and Black Ss significantly more hypothesized nonstandard English responses to each of the 4 tasks. Additionally, Ss of both races showed significant increases in standard English usage and significant decreases in nonstandard English usage over the 2-yr period. The possibility that grammatical differences between Black Ss and White Ss might disappear given more time is discussed. (20 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sibling disability and children's reactivity to conflicts involving family members.

Although rarely considered, siblings may significantly affect families in ways that have implications for other children's functioning, especially when the siblings' problems pose special difficulties. This study examined how having a disabled sibling predicted children's reactions to the everyday stress of family-related conflicts. Thirty children with a disabled sibling (15 boys, 15 girls) and 30 with nondisabled siblings (15 boys, 15 girls) responded to a series of disputes involving other family members. Having a disabled sibling predicted sensitization to these everyday family stresses, including more emotional distress; more expected involvement, perceived threat, and personal responsibility; more active coping strategies; and lower thresholds of conflict intensity for responding. Children with disabled siblings also evidenced more adjustment problems. Although developmental outcomes of challenging family circumstances may vary considerably for individual children, these results demonstrate the potential significance of siblings to the functioning of other children in the family.

Black and White children's use of standard English at 7, 9, and 12 years of age.

A Berko-type task, requiring an S to derive the present, plural, possessive, and time extension forms of nonsense syllables, was re-administered to 64 Black and White 7th graders previously tested in Grades 2 and 4. Results indicate (a) linguistic convergence for all Ss between 4th and 7th grades on possessive, time extension, and plural tasks and (b) linguistic divergence between Black and White Ss over time on the present tense task. It is emphasized that findings be interpreted with caution because of the effect of nonrandom attrition (44%) on the longitudinally collected data.

Cynicism, social support, and cardiovascular reactivity.

This study examined whether highly cynical individuals benefit less from social support during an acute stressor than individuals low in cynicism. College students (52 men, 52 women) performed a stressful speech task alone or in the presence of a supportive confederate. There was an interactive effect of social support and cynicism on cardiovascular reactivity: Low cynicism participants who received support had smaller increases in blood pressure during the speech than low cynicism participants without support and high cynicism participants with or without support. Participants' psychological stress appeared to mediate the main effects of support on blood pressure reactivity, but not the Support?×?Cynicism interaction. Results suggest that cynical attitudes may undermine the stress buffering potential of interpersonal support. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hostility, anger-in, and cardiovascular reactivity in White women.

Relations between cardiovascular reactivity and cynical hostility, aggressiveness, antagonism, and anger-in were examined in White college women tor conditions of high and low interpersonal stress. High stress was created by having the participants discuss an issue on which they held a strong view with a confederate who adamantly espoused an opposing view. Participants in the low-stress condition discussed an issue on which they held no strong views with a confederate who amicably expressed agreement. Participants higher in cynical hostility exhibited more systolic blood pressure reactivity than individuals lower in cynical hostility in the high interpersonal stress condition only. Also, antagonism was positively related to heart rate reactivity across conditions. However, neither aggressiveness nor anger-in was related to reactivity in either condition. Overall, cynical hostility and a disposition toward disagreeable, manipulative behaviors (i.e., antagonism) but not overt aggressive behavior were found to be related to cardiovascular reactivity.

Change in children's competence beliefs and subjective task values across the elementary school years: A 3-year study.

The authors assessed change over 3 years in elementary school children's competence beliefs and subjective task value in the domains of math, reading, instrumental music, and sports. The longitudinal sample consisted of approximately 615 mostly White, lower middle to middle-class children. Stability correlations indicated moderate to strong stability in children's beliefs, especially older children's competence beliefs. The relation of children's ratings of their competence in each domain to estimates of their competence in those domains provided by both parents and teachers increased over the early elementary grades. Children's competence beliefs and ratings of the usefulness and importance of each activity decreased over time. Children's interest in reading and instrumental music decreased, but their interest in sports and math did not. Gender differences in children's competence beliefs and subjective task values did not change over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Racial differences in stress-induced cardiovascular reactivity and hypertension: Current status and substantive issues.

Essential hypertension is perhaps the number-one health problem of Black Americans. Research has indicated that stress-induced cardiovascular hyperreactivity may be a significant contributor to essential hypertension. The high prevalence of hypertension among Blacks suggests that this group, in comparison with Whites, may be particularly susceptible to cardiovascular hyperreactivity. The first portion of this article reviews research to date that has examined racial differences in resting and stressor-induced cardiovascular activity. The second half of this article overviews some critical methodological and conceptual issues involved in the study of racial differences in reactivity. These issues include the effects of Black-White differences in plasma renin levels and sodium excretion, the effects of experimenter race, and differences in perceptions of the laboratory environment. Additionally, the issue of racial group classification and the implications this has for interpreting Black-White differences in reactivity is discussed. Two perspectives on racial group classification, the genetic and the sociocultural, are addressed in some detail, and the relevance of each to research on racial differences in stress reactivity is presented.

Culture, ethnicity, and children's facial expressions: A study of European American, mainland Chinese, Chinese American, and adopted Chinese girls.

This investigation extends previous research documenting differences in Chinese and European American infants' facial expressivity. Chinese girls adopted by European American families, nonadopted Mainland Chinese girls, nonadopted Chinese American girls, and nonadopted European American girls responded to emotionally evocative slides and an odor stimulus. European American girls smiled more than Mainland Chinese and Chinese American girls and scored higher than Mainland Chinese girls for disgust-related expressions and overall expressivity. Adopted Chinese girls produced more disgust-related expressions than Mainland Chinese girls. Self-reported maternal strictness, aggravation, positive expressiveness, and cultural identification correlated with children's facial responses, as did number of siblings and adults in the home. Results suggest that culture and family environment influences facial expressivity, creating differences among children of the same ethnicity.

Acute psychophysiologic reactivity and risk of cardiovascular disease: A review and methodologic critique.

Recent behavioral and biomedical research has suggested that psychophysiologic responsiveness (reactivity) to emotional stress may be a marker of processes involved in the development of cardiovascular disorders. The assessment of reactivity focuses on acute changes in functioning as opposed to the sole assessment of resting levels of variables. Evidence is reviewed that links behaviorally induced cardiovascular and endocrine changes to coronary heart disease and essential hypertension. Particular attention is given to methodologic issues involving measurement. Different tasks and situations appear to elicit different patterns of physiologic responses. Reactivity per se should currently not be regarded as a proven risk factor. It is suggested that evidence does, however, justify continued laboratory and naturalistic hypothesis-testing research. The authors recommend methodologic studies to identify (a) the psychologic dimensions of stimuli that elicit reactivity in different subject groups, and (b) the patterns of physiologic responses produced. Such research would set the stage for epidemiologic studies to further examine relations between behavior and disease processes.

Expressions of children's grief: A qualitative study.

Explored the use of guided imagery as a tool to facilitate the expression of children's grief. The children in the study were participating in open-ended, age specific, grief groups. Nine children (aged 4–14 yrs) participated in pre- and post-guided-imagery drawings. The Rosebush drawing itself and the feelings engendered by drawing appeared to be the most important element in assessing change. At discharge, the children's drawings showed greater integration. It was concluded that the Rosebush technique can be an aid in understanding the grief process of the child. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Appraisals of marital conflict and children's adjustment, health, and physiological reactivity.

Children's appraisals of marital conflict were examined as moderators and mediators of conflict and children's adjustment, physical health, and physiological reactivity. Mothers completed measures of marital conflict and children's adjustment and physical health, and elementary school children provided information on their parents' marital conflict, appraisals of perceived threat and self-blame in relation to parents' conflicts, and their internalizing symptomatology. Children's heart rate, systolic and diastolic blood pressure, and skin conductance response and level were examined during both a baseline and an interadult argument. Higher levels of both self-blame and perceived threat functioned as robust vulnerability factors for children exposed to higher levels of marital conflict in relation to internalizing behaviors, health problems, and higher levels of cardiovascular reactivity to the argument. Further, a higher level of perceived threat was a vulnerability factor for externalizing problems associated with exposure to marital conflict.

Gender, ethnicity, and social cognitive factors predicting the academic achievement of students in engineering.

Examines the relationships of measures of occupational and academic self-efficacy; vocational interests; outcome expectations; academic ability; and perceived stress, support, and coping to the academic achievement of women and men enrolled in university-level engineering/science programs. 197 students from diverse racial/ethnic backgrounds responded to scales measuring the variables of interest; high school and college academic data were obtained from university records. Self-efficacy for academic milestones, in combination with other academic and support variables, was found to be the strongest predictor of college academic achievement. Outcome expectations, vocational interests, and low levels of stress were in turn the strongest predictors of academic self-efficacy. Prediction equations for Euro-American and Mexican-American students revealed no significant contribution of ethnicity to the prediction of college academic achievement; however, ethnicity did enter into the equations predicting the 2 self-efficacy variables.

Dimensions of creativity in children's drawings: A social-validation study.

Creative drawings of 3 preschool girls (3 and 5 yrs old) were modified using reinforcement procedures in a multiple baseline design. Clear changes were produced in the diversity of color and form. When selected drawings were shown to adult judges, higher ratings of creativity were given for drawings with increased form diversity but not for drawings with increased color diversity. Results are discussed in terms of the role of social validation in defining and encouraging creativity. (31 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Gender characteristics and adjustment: A longitudinal study.

[Correction Notice: An erratum for this article was reported in Vol 64(1) of Journal of Personality and Social Psychology (see record 2010-03552-001). The authors would like to acknowledge that the age 41 longitudinal data used in their study were collected by David McClelland, Carol Franz, Joel Weinberger, Richard Koestner, and Joseph Healy. This data collection was supported by a grant from the Seaver Institute. The data are currently being archived at the Henry Murray Research Center of Radcliffe College, Cambridge, Massachusetts.] Used a prospective longitudinal design to investigate the long-term developmental implications of gender-related interests and traits. Archival data were available for Ss in the R. R. Sears et al (1957) study. Men, who at age 12 yrs endorsed interests and undesirable traits more typically associated with women, had poorer social–personal adjustment at ages 31 and 41 yrs. No effects were found for women. Feminine expressive traits at age 31 yrs did not impact on 41-yr-old adjustment for either men or women, whereas masculine instrumental traits were positively related for both. These findings support a multidimensional view of gender and indicate that harsher consequences follow when adolescent boys endorse nontraditional gender-related interests and undesirable traits than when girls do so.

Contributions of child's physiology and maternal behavior to children's trajectories of temperamental reactivity.

Trajectories of children's temperamental reactivity (negative affectivity and surgency) were examined in a community sample of 370 children across the ages of 4 to 7 with hierarchical linear modeling. Children's physiological reactivity (respiratory sinus arrhythmia [RSA]), physiological regulation (ΔRSA), and maternal parenting behavior were included as predictors of children's trajectories of temperamental reactivity. Results indicated that negative affectivity and surgency decreased from 4 to 7 years of age; however, within-person changes in negative affectivity were dependent on levels of baseline RSA and not age. Increases in negative affectivity were also predicted by higher levels of earlier maternal controlling behavior. Decreases in surgency were predicted by higher levels of ΔRSA during mother–child interaction tasks and positive parenting behavior. Baseline RSA and maternal controlling parenting also accounted for interindividual differences in children's negative affectivity at age 7, and gender and children's baseline RSA accounted for interindividual differences in children's surgency at age 7. Overall, these results provide further evidence that parenting behavior and children's RSA influence the changes that occur in children's temperamental reactivity.
