Adolescents’ Psychological Well-Being and Memory for Life Events: Influences on Life Satisfaction with Respect to Temperamental Dispositions

The aim of the present study was to explore how the number of recalled life events (positive and negative) predicts psychological well-being (PWB) and how PWB predicts life satisfaction (LS). In addition, participants were categorized into one of four different affective temperaments (self-actualizing, high affective, low affective, and self-destructive). One hundred and thirty-five high school students participated in completing the SWLS (LS), PWB (short-version), PANAS (to create affective temperaments), and the life events recollection task. Results indicated that adolescents with high positive affect also had high PWB; adolescents with low affective profiles also had high PWB. Positive and negative life events predicted PWB for self-destructive temperaments, whereas positive life events predicted PWB for low affective temperaments. PWB predicted LS for all temperaments except the self-actualizing group. In conclusion, the temperament combinations may allow the individual to achieve PWB and LS. Even more importantly, selfacceptance may foster LS regardless of temperament and may have more impact on LS than life events.     

Robust patterns and individual variations: Stability and predictors of infant behavior in the still-face paradigm

In the present study we examined key issues regarding infant behavior in the still-face paradigm (SFP) in terms of individual variations, stability, and predictors. The sample consisted of 115 mothers and infants, with assessments at ages 3 and 6 months, including observations of maternal and infant behavior in the SFP, and parent reports of infant temperament. Both robust patterns and individual variations in infant SFP behaviors were found, with only a minority of infants showing the expected patterns for negative affect and gaze. Infant behavior patterns showed no stability from age 3 to 6 months, and infant gaze was related to more pronounced behavior changes across the SFP. Maternal sensitivity in the SFP baseline was related to some aspects of infant SFP behavior. Consistent with the differential susceptibility hypothesis, in infants with a more difficult temperament maternal sensitivity predicted a more pronounced expected pattern of changes in infant positive affect across the SFP, whereas this was not the case for infants with a more easy temperament.     

Maternal psychological functioning mediates the association between infant behavior and subsequent child psychological functioning

Symptoms of psychopathology that onset during childhood are often more severe, chronic, and difficult to treat than symptoms that first appear later in life. Maternal psychological symptoms are associated with the development of psychological symptoms in children. However, less research focuses on whether children’s behaviors may presage maternal psychological difficulties that, in turn, contribute to the child’s own psychological functioning. Identifying psychological difficulties in families and intervening in early life may lower risk for intergenerational transmission of subsequent psychological symptoms. Even at non-clinical or normative levels, exploring transactional models of parent-child behavior and psychological functioning may provide insight into the development of later psychological difficulties or symptoms within families. Thus, the current study examined whether difficult infant behavior (e.g., fussiness, unpredictability) is associated with future maternal psychological difficulties and subsequently, the child’s own psychological functioning in early childhood. The current sample includes 847 dyads from a multi-wave birth cohort in England (‘Born in Bradford’), who identified as predominantly non-White (62.2%) and socioeconomically diverse. Mothers reported on their child’s behaviors at 6 months, their own psychological functioning during pregnancy and at 18 months postpartum, and their child’s psychological functioning at age 3. Results of a mediation model revealed that the association between infant behavior at 6 months and child psychological functioning at 3 years is partially explained by maternal psychological functioning at 18 months, even after accounting for psychological difficulties during pregnancy, maternal age at birth, child sex, family income, and ethnicity. Post-hoc exploratory analyses revealed that the association between infant behavior, maternal psychological functioning, and subsequent child psychological functioning was significant for Pakistani British families but not White British families. These findings provide preliminary evidence that infant behaviors (e.g., temperament) may presage future maternal psychological difficulties and subsequent child psychological functioning, above and beyond previous maternal psychological functioning. Importantly, these results highlight infant behavior as a potential catalyst for later psychological difficulties within families.     

Development of behavioural regulation in Do and Don't contexts among behaviourally inhibited Chinese children

Behavioural inhibition influences the development of behavioural regulation in early childhood. Previous studies have mainly focused on the relationship between inhibition and regulation in the Don't context (e.g., inhibitory control), while few have investigated this relationship in the Do context (e.g., task persistence). This longitudinal study examined the effect of temperamental inhibition on behavioural regulation during both the Do and Don't contexts in 112 Chinese preschoolers. At 3.5 years of age, children's behavioural inhibition was assessed by behavioural observation and parental report, and then at 4.5 years of age, their regulatory behaviours were measured in the following two challenging contexts: Do [locked box (LB)] and Don't [toy inhibition (TI)]. In each task, children were randomly assigned to either a high‐ or a low‐incentive condition designed to vary the value of a given goal. Results suggested that higher inhibition was associated with poorer regulation (lower task persistence) in both conditions of the Do context (LB), whereas in the Don't context (TI) highly inhibited children showed better regulation (less violation behaviours) in the low‐incentive condition than they did in the high‐incentive condition. The results highlight the context characteristics and goal incentive as important factors for behavioural regulation development in inhibited children in China.     

Sex differences in brain activity, personality and intelligence: a test of arousability theory

This report describes empirical tests of the theory that females have higher levels of behavioural and cerebral arousal than males and that these differences cause higher neuroticism scores in females, as well as lower female psychoticism scores and lower scores for females on the Gsar factor of intelligence. Data were obtained from 76 subjects, with equal numbers of males and females and with all adult ages represented. EEG responses to auditory stimulation were quantified in terms of the ‘amplitude, ‘rate of change of amplitude and ‘sweep variability factors obtained from a principal components analysis (PCA). Gf, Gc and Gsar intelligence scores were obtained from a PCA of sub-tests from the Wechsler Adult Intelligence Scale plus Ravens Advanced Progressive Matrices test. Personality differences were evaluated using the Neuroticism and Psychoticism scales of the Eysenck Personality Questionnaire (EPQ). Bivariate hypotheses relating sex to the arousal, intelligence and personality variables were confirmed. A PCA demonstrated that sex, neuroticism, Gsar, wakefulness and high frequency EEG activity all have high loadings on a common factor. These results are consistent with expectations generated by the cerebral arousability theory of personality and intelligence.     

Does temperament influence language development? Evidence from preterm and full-term children

The aims of this study are: (1) to describe language and temperament characteristics of one group of low risk preterm (PR) children and a group of full-term (FT) children and (2) to identify those factors which can predict language outcomes at 30 months of age, with special attention on temperament. There is evidence of differences between very or extremely PR and FT children in relation to characteristics of temperament and language development. However, not many studies have been carried out with healthy PR children.The participants were 142 low risk PR children (mean gestational age (GA): 32.60 weeks) and 49 FT children (mean GA 39.84 weeks). The temperament of the children was assessed at 10 months of age through the Infant Behavior Questionnaire-Revised (IBQ-R). At 22 months of age the cognitive development of the children was assessed through the Spanish adaptation of the Batelle Developmental Inventory (BDI). In order to assess the children's language development the Galician adaptation of the MacArthur–Bates CDI was applied at 30 months of age. In addition, socio-demographic information about the children and their families was gathered at birth.The results indicate that there were no significant differences in the language measures of interest (word production, MLU3, and sentence complexity) between groups. The only differences found between the PR and the FT children in the IBQ-R were restricted to the smiling and laughter and the fear subscales. Hierarchical regression analyses performed indicate that GA did not have any predictive effect on language measures taken at 30 months. Cognitive scores were an important predictor of language measures, although certain temperament subscales contributed in a significant way to the variance of language measures, particularly low intensity pleasure, approach, high intensity pleasure, sadness, and vocal reactivity. Therefore, extroverted (positive affectivity) temperament seems to be beneficial for language development.     

Why do parents use screen media with toddlers? The role of child temperament and parenting stress in early screen use

Considering child characteristics may be an important piece to understanding parental decision-making for children’s screen use. The current cross-sectional study examined the mediating role of maternal parenting stress in the relation of child temperament to young children’s screen use. Recognizing the multidimensional aspects of temperament, three mediated pathways for three temperament domains (i.e., negative affectivity, surgency, and effortful control) were tested. Mothers of toddlers, 18–36 months (N = 296), completed an online survey, reporting on child temperament, total parenting stress, and child screen use. The results showed that mother-child dynamics were related to toddlers’ screen use. Toddlers’ negative affectivity and effortful control were each associated with toddlers’ screen use through maternal parenting stress. Higher negative affectivity was associated with higher maternal parenting stress, which in turn, was related to greater screen use in toddlers. Toddlers’ lower effortful control was related to higher maternal parenting stress, which in turn, was associated with greater screen use. Toddlers’ surgency was not related to either maternal parenting stress or toddlers’ screen use. The findings from this study contribute to an understanding of media-related parenting in toddlerhood and may help with the development of strategies for supporting healthy media habits in families with young children.     

Temperament moderates the effect of the verbal threat information pathway on children's heart rate responses to novel animals

Temperamental variables such as trait anxiety are risk factors in children for the development of anxiety disorders. This experiment aimed to test whether temperament moderates the effect of verbal threat information on the physiological component of the fear emotion. An experiment is reported in which 6-10 year old children's (N = 54) fear beliefs about novel animals were measured. They were then given threat, positive or no verbal information about these animals following which their heart rate was recorded while they placed their hands in boxes that they believed these animals inhabited. Children also completed a questionnaire measure of trait anxiety. Child-reported temperament moderated the effect that threat information has on the physiological component of the fear emotion. Fear information is, therefore, a possible mechanism through which temperament leads children to acquire animal fears.     

Toddler emotional states,temperamental traits,and their interaction: Associations with mothers’ and fathers’ parenting

We investigated the degree to which toddlers’ observed emotional states, toddlers’ temperamental traits, and their interaction accounted for variance in mothers’ and fathers’ parenting. Main effects of two emotional states (positive emotion and negative emotion), three temperamental traits (negative affectivity, effortful control, and surgency) as well as state-by-trait interactions, were examined in relation to parental sensitivity, positive affect, and negative affect. The hypothesis that toddlers’ temperamental traits would moderate the association between their observed emotional states and parenting was partially supported. Significant state-by-trait interactions were found in models predicting the probability that mothers and fathers expressed negative affect toward their toddlers. For parental sensitivity and positive affect, only main effects of temperament and/or emotion expression accounted for variance in parenting.     

East–west,collectivist-individualist: A cross-cultural examination of temperament in toddlers from Chile,Poland, South Korea,and the U.S.*

The present study examined toddler temperament across Chilean, South Korean, Polish, and U.S. samples, providing an opportunity to examine both collectivist-individualist and East–West contrasts. The effect of culture on the three factor and 18 dimension scores provided by the Early Childhood Behavior Questionnaire were investigated. Results provide evidence of cross-cultural differences between the four samples. Chilean toddlers scored significantly higher than U.S., Polish, and South Korean children on the overall factor of Negative Affectivity, as well as higher than the Polish and South Korean samples on the Surgency factor. South Korean toddlers scored significantly higher on the factor of Effortful Control, and two related dimensions, than U.S., Polish, or Chilean samples. Results are discussed in terms of the apparent roles of individualism/collectivism and East–West distinctions in shaping temperament development.
