The integration of cognition and emotion during infancy and early childhood: regulatory processes associated with the development of working memory

This study was an attempt to integrate cognitive development (i.e., cognitive control) and emotional development (i.e., emotion regulation) in the first years of life. The construct of temperament was used to unify cognition and emotion because of its focus on attentional and regulatory behaviors. Children were seen at 8 months and 412-years of age in a study designed to examine the correlates of working memory development. Frontal brain electrical activity and temperament predicted working memory performance at 8 months. Similarly, frontal brain electrical activity, temperament, and language predicted working memory at age 412-years. Temperament in early childhood mediated the relation between infant temperament and early childhood working memory performance. These associated temperament characteristics highlight the value of early-learned regulatory and attentional behaviors and the impact of these early skills on later development.     

Relations of Neuroticism and Attentional Control with Symptoms of Anxiety and Aggression in Non-Clinical Children

The present study examined the associations between neuroticism and attentional control and the occurrence of symptoms of psychopathology in children. A large sample of non-clinical children aged 9 to 17 years (N = 409) completed questionnaires measuring neuroticism, attentional control, and symptoms of anxiety and aggression. Results demonstrated that neuroticism was positively associated with symptoms of anxiety and aggression, whereas attentional control was negatively linked to such symptoms. Regression analyses showed that both neuroticism and attentional control accounted for an independent and significant proportion of the variance in children’s anxiety and aggression symptoms. Further, tentative support was found for the notion that neuroticism and attentional control have an interactive effect on symptoms of anxiety and aggression. Results did not show that age had an influence on the emergence of this interaction.     

The effect of inpatient cognitive-behavioral therapy for eating disorders on temperament and character

Personality traits seem to have an important role in the development, clinical expression, course, and treatment response in eating disorders (EDs). We investigated the effects of an inpatient cognitive-behavioral treatment (CBT) on the measures of temperament and character (Temperament and Character Inventory (TCI)) in 149 consecutive patients with EDs. Baseline assessment included anthropometry, the Eating Disorder Examination (EDE), the Beck Depression Inventory (BDI), and the TCI. Treatment was based on the transdiagnostic cognitive behavior theory and treatment of ED, adapted for an inpatient setting. Treatment effects were tested by paired ANOVA, adjusted for covariates. No effects were found on Novelty Seeking, Reward Dependence, and Cooperativeness. Harm Avoidance (F=18.17, p<0.001), Persistence (F=7.71, p=0.006), Self-Directedness (F=27.55, p<0.001), and Self Transcendence (F=16.38, p<0.001) significantly changed after treatment. Changes in TCI scores were wholly dependent on the changes in BDI and EDE, and independent of ED diagnosis and behavior and of BMI changes. We conclude that in ED, a few scales of both temperament and character are significantly modified by CBT, in relation to changes in psychopathology and depression, independently of nutrition. These results are relevant for future studies based on TCI.     

Genetics and personality affect visual perspective in autobiographical memory

Major depression is associated with a decrease of 1st person (versus 3rd person) visual perspective in autobiographical memory, even after full remission. This study aimed to examine visual perspective in healthy never-depressed subjects presenting with either genetic or psychological vulnerability for depression. Sixty healthy participants performed the Autobiographical Memory Test with an assessment of visual perspective. Genetic vulnerability was defined by the presence of at least one S or L_G allele of the polymorphism of the serotonin-transporter-linked promoter region (5-HTTLPR). Psychological vulnerability was defined by high scores of harm avoidance measured by the Temperament and Character Inventory. Life stress exposure, depressive mood, rumination, and familial history of depression were assessed through standardized procedures. Visual perspective for positive memories was independently predicted by both harm avoidance and a gene by environment interaction between the 5-HTTLPR polymorphism and life stress exposure. Visual perspective and vulnerability for depression may share some biological bases.     

Temperament and its Relationship to Autistic Symptoms in a High-Risk Infant Sib Cohort

The present study prospectively investigated early temperamental profiles and their associations with autistic symptoms in high-risk infants (N = 138) with an older sibling with autistic spectrum disorder (ASD) and low-risk infants (N = 73) with no family history of ASD. Children who were diagnosed with ASD at 36 months were distinguished from non-ASD sibs and controls by a temperament profile marked by lower positive affect, higher negative affect and difficulty controlling attention and behavior, which we labeled Effortful Emotion Regulation. This profile also distinguished the non-ASD sib group from the control group. Children with ASD were distinguished from both of the other two groups by a temperament profile of low Behavioral Approach (lower sensitivity to “social” reward cues). Low levels of Behavioral Approach were associated with a higher number of ASD symptoms, even after taking into account IQ, sex and group membership. Finally, a cluster analysis revealed two ASD subgroups distinguished by number of ASD symptoms, IQ, age of diagnosis and scores on the Behavioral Approach profile. These findings suggest that temperament may be a useful framework for understanding the emergence of ASD early in life.     

Mediational Pathways Through Which Positive and Negative Emotionality Contribute to Anhedonic Symptoms of Depression: A Prospective Study of Adolescents

This study takes a developmental psychopathological approach to examine mechanisms through which baseline levels of positive emotionality (PE) and negative emotionality (NE) prospectively predict increases in anhedonic depressive symptoms in a community sample of 350 adolescents (6th–10th graders). Dependent stressors mediated the relationship between baseline levels of NE and anhedonic depressive symptoms after controlling for initial symptoms. Supportive relationships mediated the relationship between baseline levels of PE and anhedonic depressive symptoms, after controlling for baseline symptoms. In addition, NE X PE interacted to predict later anhedonic depressive symptoms, such that adolescents with low levels of PE and high levels of NE experienced the greatest increase in anhedonic depressive symptoms. Last, supportive relationships interacted with baseline PE to predict prospective changes in anhedonic depressive symptoms, such that adolescents with low PE and low supportive relationships experienced the greatest increase in anhedonic depressive symptoms. Results are discussed in terms of current theoretical models of the link between temperament and depression.

Negative Affectivity, Effortful Control, and Attention to Threat-Relevant Stimuli

There is increasing recognition of temperamental influences on risk for psychopathology. Whereas the link between the broad temperament construct of negative affectivity (NA) and problems associated with anxiety and depression is now well-established, the mechanisms through which this link operate are not well understood. One possibility involves interactions between reactive and effortful components of temperament, as well as cognitive factors, like attentional biases to threat stimuli. This study tested a predicted relation between high levels of NA, low levels of effortful control (EC), and an attentional bias toward threat in children. A sample of 104 4th through 12th graders, selected from a larger screening sample because they reported high or low levels of trait NA and EC, completed a dot probe detection task. Results indicated that EC moderated the relation between NA and attentional bias; only children with low levels of EC and high levels of NA showed an attentional bias to threat stimuli. This pattern was not moderated by grade level or age.

Socio‐emotional development: From infancy to young adulthood

Results from the Uppsala Longitudinal Study (ULS), which started in 1985, are reported in two sections. The first section gives a summary of longitudinal data from infancy to middle childhood (age 9 years; n = 96) concerning predictions of social functioning aspects from the theoretical perspectives of temperament, attachment, and health psychology (social factors). The second section presents the first results emanating from a follow‐up when participants were 21 years old (n = 85). The developmental roots of social anxiety symptoms were studied from the same perspectives as above, although with a special focus on the predictive power of the temperament trait of shyness/inhibition. Results for middle childhood outcomes showed that temperament characteristics were relevant for most outcomes, whereas the contribution of attachment was most convincingly shown in relation to social competence and personality. Social factors were found to have moderating functions, but direct effects were also shown, the most interesting perhaps being positive effects of non‐parental day care. Results from the 21‐year data confirmed the expected predictive relation from shyness/inhibition to symptoms of social anxiety and further showed this relation to be specific; the relation to symptoms of depression did not survive control for social anxiety, although the opposite was true. The broad analysis of predictor associations with social anxiety, showing the relevance of other temperament factors as well as interactive effects, again attested to the need for multi‐faceted models to analyze developmental trajectories.     

What is the temperamental basis of humour like in China? A cross-national examination and validation of the standard version of the state–trait cheerfulness inventory

The State–Trait Cheerfulness Inventory–trait version (STCI-T60) consists of three dimensions of cheerfulness, seriousness, and bad mood integrated to measure the temperamental basis of the sense of humour. The present study replicated the three-dimensional factor structure of the STCI in China using 60 items consistent with other standard trait versions (e.g., English, Chilean-Spanish). Closer examination of associations between traits suggested bad mood showed curvilinear associations with both cheerfulness and seriousness, such that cheerfulness and bad mood were negatively associated for those low and average in trait bad mood but not for those with high trait bad mood. Seriousness was positively associated with bad mood at high levels of trait bad mood, but not at average or low levels of bad mood. Associations between the STCI traits and major personality dimensions, humour styles, and well-being were further examined. Cheerfulness and seriousness showed positive associations with satisfaction with life and emotional well-being (EWB) while bad mood showed a curvilinear association with EWB. Using multi-group confirmatory factor analyses, partial metric invariance was found between English and Chinese versions of the STCI-T60, but structural invariance was not observed. Implications based on the empirical literature in dialecticism and cross-cultural assessment were thoroughly discussed.     

Toddler emotion expressions and emotional traits: Associations with parent-toddler verbal conversation

The present study examines how toddler emotions may influence their own or their parents’ participation in parent-toddler verbal conversation. Limited, indirect evidence suggests that toddler positive emotions may encourage, whereas negative emotions may disrupt, parent-toddler verbal exchanges, but these hypotheses have not been tested directly. We investigated two aspects of toddler emotions– their emotion expressions and their emotional traits– and examined their relations with parent-toddler verbal conversation engagement. In a sample of families with 18-month-olds (N = 120), we used live, unstructured home observations of toddler emotion expressions and spontaneous parent-toddler verbalizations, and collected parent ratings of toddler temperament. We found that less surgent toddlers who expressed more frequent negative emotion attempted fewer verbalizations. Among all toddlers, those expressing positive emotion received more frequent parent verbal responses, and, unexpectedly, more failed parent attempts to engage their toddler in conversation. Parent-initiated conversation was unrelated to toddler emotion expressions or emotional traits. We discuss how best to integrate the study of early emotional and language development from a transactional perspective.
