青少年反应性攻击和结果评价的ERPs研究：基于自我控制资源的视角

采用竞争反应时任务并结合ERPs技术,以39名高中生为有效被试,从自我控制资源的视角揭示青少年反应性攻击和结果评价的电生理机制。行为结果发现：高自我损耗者比低自我损耗者表现出更多攻击行为;ERPs结果发现：(1) 在攻击决策阶段,高自我损耗者前脑区域所诱发的P2波幅显著高于低自我损耗者;(2) 在结果评价阶段,“输”反馈比“赢”反馈诱发更负的FRN成分,且仅在“输”反馈条件下,高自我损耗者比低自我损耗者所诱发的FRN更负。从一定程度上说明自我损耗是导致青少年反应性攻击行为的重要原因,高自我损耗会加剧反应性攻击行为的发生。     

TEMPERAMENTAL ADAPTABILITY,PERSISTENCE, AND REGULARITY: PARENTAL RATINGS OF NORWEGIAN INFANTS AGED 6 TO 12 MONTHS,WITH SOME IMPLICATIONS FOR PREVENTIVE PRACTICE

There is a need for standardized measures of infant temperament to strengthen current practices in prevention and early intervention. The present study provides Norwegian data on the Cameron‐Rice Infant Temperament Questionnaire (CRITQ; J.R. Cameron & D.C. Rice, 1986a), which comprises 46 items and is used within a U.S. health maintenance organization. The CRITQ was filled out by mothers and fathers at 6 and again at 12 months as part of a longitudinal study of mental health during the first years of life (the “Little in Norway” study, N = 1,041 families enrolled; V. Moe & L. Smith, 2010). Results showed that internal consistencies were comparable with U.S. data. The temperament dimensions of persistence, adaptability, and regularity had acceptable or close‐to‐acceptable reliabilities in the U.S. study as well as in this study, and also were unifactorial in confirmatory factor analysis. These dimensions are the focus in this article. Findings concerning parents’ differential ratings of their infants on the three dimensions are reported, as is the stability of parents’ ratings of temperament from 6 to 12 months. In addition, results on the relation between temperament and parenting stress are presented. The study suggests that temperamental adaptability, persistence, and regularity may be relevant when assessing infant behavior, and may be applied in systematic prevention trials for families with infants. The inclusion of concepts related to individual differences in response tendencies and regulatory efforts may broaden the understanding of parent—infant transactions, and thus enrich prevention and sensitizing interventions with the aim of assisting infants’ development.     

Mother's personality and infant temperament

We examined if perfectionism and the perception of being an anxious person were associated with more negative infant temperament ratings by the mothers. 386 women (mean age = 30.08; standard deviation = 4.21) in their last trimester of pregnancy completed the Multidimensional Perfectionism Scale (MPS), the Beck Depression Inventory-II (BDI-II) and an item about their perception of being or not an anxious person. The Portuguese version of the Diagnostic Interview for Genetic Studies and the Operational Criteria Checklist for Psychotic Illness were used to generate diagnoses according to DSM-IV and ICD-10 criteria. After delivery, women completed eight items of the Difficult Infant Temperament Questionnaire (developed by our team) and filled in, again, the BDI-II and were interviewed with the DIGS. Women with depression (DSM-IV/ICD-10) and probable cases of depression using different cut-offs adjusted to Portuguese prevalence (BDI-II), in pregnancy and postpartum, were excluded. The Difficult Infant Temperament Questionnaire showed to have factorial validity and internal consistency. There was a statistically significant negative correlation between perfectionism total scale score and item 6 from the temperament scale (“is your baby irritable or fussy?”). Considering MPS 3-factor solution found for pregnancy there was also a statistically significant negative correlation between SOP and the same item. Women with low SOP differed from those with medium and high SOP in the total temperament score. Moreover, the low SOP group differed from the medium group on items three and four scores. There were no significant associations with SPP, which is the dimension more closely associated with negative outcomes. There was an association between anxiety trait status (having it or not) and scoring low, medium or high in the infant temperament scale. The proportion of anxious vs. non-anxious women presenting a high score on the infant temperament scale was higher (24.2% vs. 12.9%). Linear regressions showed that SOP (low vs. medium/high) offered a significant contribution to the prediction of total temperament scale score and items 3 and 4 scores, but a logistic regression did not confirm trait anxiety as a significant predictor of mother's infant temperament perception. Concluding, a major result concerns the fact that higher levels of adaptive perfectionism (i.e. SOP) are associated (and predict) a less negative view of their infant's temperament. These results on the effect of mother's anxiety and perfectionism on the child temperament perception might have treatment implications. As perfectionism is not always maladaptive, some of its positive features could be used to enhance women's self-efficacy/sense of parental competence in their role as mothers and positive affect towards their infants. Also, antenatal interventions aimed at minimising anxiety could help to optimise infant temperament outcomes, which could, eventually, also, lead to subsequent maternal and infant mental health better outcomes.     

Marital aggression predicts infant orienting toward mother at six months

Links between marital aggression and infant orienting toward mother in fearful and frustrating contexts were examined in 92 mother-infant dyads when infants were six months. Results demonstrated that marital aggression was linked with less orienting toward mothers in frustrating situations, in fearful situations marital aggression was linked with less orienting among infants who were high on fear reactivity only.     

Infant's psychophysiological profile and temperament at 3 and 12 months

This study is intended to analyze (1) differences in infant temperament at 3 and 12 months according to infants’ psychophysiological profiles: “withdrawn” “extroverted”, and “underaroused” and (2) changes in infant temperament from 3 to 12 months, namely according to the infant psychophysiological profile and the quality of mother-infant interaction. Ninety-four 8-week-old infants were assessed using the Neonatal Behavioral Assessment Scale (NBAS, Brazelton & Nugent, 1995) and the Alarm Distress Baby Scale (ADBB, Guedeney & Fermanian, 2001). Saliva samples were collected at 8-12 weeks old, both before and after a routine inoculation for cortisol reactivity measurement. Mother-infant interaction was evaluated at 12-16 weeks, using the Global Rating Scales (GRS, Murray, Fiori-Cowley, Hooper, & Cooper, 1996). Mothers’ reports on infant temperament at 3 and 12 months were collected using the Infant Behavior Questionnaire (IBQ, Rothbart, 1981). Significant differences in mothers’ perception of infant temperament were found at both 3 and 12 months in infants with distinct psychophysiological profiles. Stability was observed in most of the temperament's dimensions from 3 to 12 months old; still, there were changes in mothers’ perception of infant temperament in terms of level of distress, cuddliness, sadness and approach. Infant psychophysiological profile and mother-infant interaction both influence with the pattern of those changes. The results corroborate that infant's characteristics early in life as well as contextual factors influence with mothers’ perception of infant temperament and with changes across the 1st year of life.     

Maternal positive parenting style is associated with better functioning in hyperactive/inattentive preschool children

Many preschoolers are highly inattentive, impulsive, and hyperactive; but only some are impaired in their functioning. Yet factors leading to functional impairment, above and beyond the severity of inattentive and hyperactive symptoms, have not been systematically examined. This study examined a model suggesting that after controlling for attention‐deficit/hyperactivity disorder (ADHD) symptom severity, child temperament is uniquely associated with parenting stress; that parenting stress affects parenting style, above and beyond child characteristics; that parenting style is related to the level of child impairment, above and beyond the effects of child symptoms, temperament, and parenting stress; and finally that parenting style moderates the relationship between ADHD symptom severity and child functioning. Child measures included parent‐ and teacher‐rated ADHD symptom severity, teacher‐rated temperament, and clinician‐rated functioning in a sample of 138 inattentive/hyperactive preschoolers. Maternal self‐ratings of parenting style and parenting stress were obtained. Analyses indicated that, after controlling for symptom severity, child temperament was related to maternal parenting stress, which was additionally related to both maternal parenting style and child functioning. Maternal positive parenting style moderated the relationship between ADHD symptom severity and child impairment, indicating that a positive parenting style plays a protective role in the functioning of hyperactive/inattentive preschoolers.

Temperament and sleep–wake behaviour from infancy to toddlerhood

Sleep–wake behaviours and temperament were examined longitudinally for trait stability and relationship to behavioural state regulation from infancy to early childhood. Subjects were 120 low‐risk, full‐term infants from a middle class sample. At 6 weeks, parents completed three consecutive days of the Baby's Day Diary which measures sleep, wake, fuss, feed and cry states and the Infant Characteristics Questionnaire. At 16 months, parents assessed sleep behaviours with the Sleep Habits Inventory and temperament with the Toddler Symptom Checklist. At 24 months, parents repeated 3 days of the Baby's Day Diary. Structural Equation Modelling was used to examine the cross‐age hypotheses for sleep–wake and temperament associations. From early infancy to toddlerhood, sleep–wake behaviours and irritable temperament were notably stable but independent in this cohort. Copyright © 2011 John Wiley & Sons, Ltd.     

Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates

Hintsanen, M., Alatupa, S., Pullmann, H., Hirstiö‐Snellman, P. & Keltikangas‐Järvinen, L. (2010). Associations of self‐esteem and temperament traits to self‐ and teacher‐reported social status among classmates. Scandinavian Journal of Psychology 51, 488–494. The present study examined the validity of self‐ and teacher‐reported social status and its relations to self‐esteem and temperament in a geographically representative cohort of Finnish adolescents (N = 3941, mean age 15.1 years). High agreement was found between self‐ and teacher‐rated social status (r = 0.42). Different aspects of self‐esteem were differently related to social status. When other temperament and self‐esteem variables were included in the analyses, strongest predictor for self‐rated social status in both genders was social self‐esteem (p < 0.01) and for teacher‐rated social status general self‐esteem (p < 0.01). The strongest temperamental predictors of social status were lower inhibition in girls (p < 0.01, self‐ and teacher‐rated) and higher impulsivity (p < 0.01, self‐rated) and activity (p < 0.01, teacher‐rated) in boys. The present findings are consistent with the view that social functioning and peer relations are associated with individual differences in self‐concept and temperament dimensions.     

Adult temperament and childbearing over the life course

Emerging evidence suggests that temperament may predict childbearing. We examined the association between four temperament traits (novelty seeking, harm avoidance, reward dependence and persistence of the Temperament and Character Inventory) and childbearing over the life course in the population‐based Cardiovascular Risk in Young Finns study (n = 1535; 985 women, 550 men). Temperament was assessed when the participants were aged 20–35 and fertility history from adolescence to adulthood was reported by the participants at age 30–45. Discrete‐time survival analysis modelling indicated that high childbearing probability was predicted by low novelty seeking (standardized OR = 0.92; 95% confidence interval 0.88–0.97), low harm avoidance (OR = 0.90; 0.85–0.95), high reward dependence (OR = 1.09; 1.03–1.15) and low persistence (OR = 0.91; 0.87–0.96) with no sex differences or quadratic effects. These associations grew stronger with increase in numbers of children. The findings were substantially the same in a completely prospective analysis. Adjusting for education did not influence the associations. Despite its negative association with overall childbearing, high novelty seeking increased the probability of having children in participants who were not living with a partner (OR = 1.29; 1.12–1.49). These data provide novel evidence for the role of temperament in influencing childbearing, and suggest possible weak natural selection of temperament traits in contemporary humans.

Experimentally manipulated change in children's proactive and reactive aggressive behavior

The current study assessed the effectiveness of two behavior manipulations created to differentially lower aggressive responses in a laboratory task. It was hypothesized that the reactive anger manipulation would have the greatest effect for reactive aggressive behavior and the instrumental manipulation would significantly affect proactive aggressive behavior and slightly affect the reactive behavior. Fifty participants played pinball in competition for points against an unknown peer, whose responses were actually controlled by the experimenter. Participants could push a noise button, sending the peer an annoying noise; a tilt button, interfering with the opponent's game; or a no answer button, offering a pro‐social alternative to aggression. After playing four rounds, participants were randomly assigned to either a reactive anger or a positive instrumental manipulation group; they then played pinball again for four rounds. Results indicate that the instrumental manipulation significantly lowered aggressive responses for both reactive and proactive behavior. The reactive manipulation effected aggressive responses only for use of the noise button and produced significantly lower levels of anger. Aggr. Behav. 29:215–227, 2003. © 2003 Wiley‐Liss, Inc.
