Cool and hot executive function problems in young children: linking self-regulation processes to emerging clinical symptoms.

Self-regulation (SR) difficulties are implicated in a wide range of disorders which develop in childhood, including attention deficit hyperactivity disorder (ADHD), oppositional defiance disorder (ODD), anxiety and depression. However, the integration of the existing research evidence is challenging because of varying terminology and the wide range of tasks used, as well as the heterogeneity and comorbidity within and across diagnostic categories. The current study used the Research Domain Criteria (RDoC) framework to guide the examination of different SR processes in young children showing a wide range of symptomatology. Children (aged 4-8) referred by teachers for moderate-to-high conduct, hyperactivity and/or emotional problems at school (assessed using the Strengths and Difficulties Questionnaire (SDQ) subscales; n = 212), and children in SDQ typical ranges (n = 30) completed computerised cognitive control and decision-making tasks. Parents completed questionnaires to assess ADHD, ODD, anxiety and depression symptoms (n = 191). Compared to children with no teacher-reported difficulties, those with moderate-to-high problems showed poorer visuomotor control and decision-making. A factor analysis revealed that task variables adhered to RDoC dimensions and predicted variance in specific disorders: difficulties in cognitive control predicted ADHD symptoms, low reward-seeking was associated with depression and high reward-seeking was associated with ODD. This study highlights how the assessment of cognitive processes positioned within the RDoC framework can inform our understanding of disorder-specific and transdiagnostic difficulties in SR which are associated with diverse clinical symptoms in children.

Childhood Antisocial Behavior: A Neurodevelopmental Problem.

Early-onset disruptive, aggressive, and antisocial behavior is persistent, can become increasingly serious as children grow older, and is difficult to change. In 2007, our group proposed a theoretical model highlighting the interplay between neurobiological deficits and cognitive and emotional functioning as mediators of the link between genetic influences and early social adversity, on the one hand, and antisocial behavioral problems in childhood, on the other. In this article, we review the post-2007 evidence relevant to this model. We discuss research on genetics/epigenetics, stress/arousal regulation, and emotion and executive functioning in support of the argument that antisocial children, especially those who persist in engaging in antisocial behavior as they grow older, have a range of neuropsychological characteristics that are important in explaining individual differences in the severity and persistence of antisocial behavior. Current clinical practice tends not to acknowledge these individual neuropsychological risk factors or to target them for intervention. We argue that aggressive and disruptive behavior in childhood should be regarded as a neurodevelopmental problem and that intervening at the level of mediating neuropsychological processes represents a promising way forward in tackling these serious behavioral problems.

Emotional and socio-cognitive processing in young children with symptoms of anxiety.

Many children with anxiety disorders exhibit significant and persistent impairments in their social and interpersonal functioning. Two components essential for successful social interaction are empathy and theory of mind (ToM). Both constructs develop rapidly in childhood, but no study has simultaneously examined these skills in young children with emerging mental health problems, including those with symptoms of anxiety. This study investigated empathy and ToM in children with anxiety symptomatology and examined their relationship with anxiety severity. A cross-sectional study was carried out with 174 children aged 4-8 years with emerging mental health difficulties who were referred by school teachers for an assessment because of emotional, cognitive, or behavioural problems at school. Participants completed empathy and ToM tasks. Parents were interviewed and rated children's emotional and behavioural problems. Correlational analyses indicated that elevated anxiety was associated with better cognitive ToM and worse affective empathy; there were no associations between anxiety and either cognitive empathy or affective ToM. Subsequent regression analyses demonstrated that whilst enhanced cognitive ToM was explained by age and verbal IQ, anxiety symptoms uniquely predicted impaired affective empathy. These results indicate that children with symptoms of anxiety have difficulty in sharing in other people's emotions. As a result, they may find it difficult to behave in socially adequate ways in interactions with others that involve affective sharing. These findings encourage the use of early and targeted interventions that improve affective empathy development in children with anxiety symptoms.

Facial emotion recognition in adopted children.

Children adopted from public care are more likely to experience emotional and behavioural problems. We investigated two aspects of emotion recognition that may be associated with these outcomes, including discrimination accuracy of emotions and response bias, in a mixed-method, multi-informant study of 4-to-8-year old children adopted from local authority care in the UK (N = 42). We compared adopted children's emotion recognition performance to that of a comparison group of children living with their birth families, who were matched by age, sex, and teacher-rated total difficulties on the Strengths and Difficulties Questionnaire (SDQ, N = 42). We also examined relationships between adopted children's emotion recognition skills and their pre-adoptive histories of early adversity (indexed by cumulative adverse childhood experiences), their parent- and teacher-rated emotional and behavioural problems, and their parents' coded warmth during a Five Minute Speech Sample. Adopted children showed significantly worse facial emotion discrimination accuracy of sad and angry faces than non-adopted children. Adopted children's discrimination accuracy of scared and neutral faces was negatively associated with parent-reported behavioural problems, and discrimination accuracy of angry and scared faces was associated with parent- and teacher-reported emotional problems. Contrary to expectations, children who experienced more recorded pre-adoptive early adversity were more accurate in identifying negative emotions. Warm adoptive parenting was associated with fewer behavioural problems, and a lower tendency for children to incorrectly identify faces as angry. Study limitations and implications for intervention strategies to support adopted children's emotion recognition and psychological adjustment are discussed.

Investigating the associations between irritability and hot and cool executive functioning in those with ADHD.

BACKGROUND: Irritability is especially pertinent to those with Attention Deficit Hyperactivity Disorder (ADHD) as it is highly prevalent and associated with a more severe clinical presentation and poorer longitudinal outcomes. Preliminary evidence suggests that top-down cognitive processes taking place in emotional contexts (i.e., hot executive functions) as opposed to those evoked in abstract scenarios (i.e., cool executive functions) may be relevant to the presentation of irritability in ADHD. This study explored the cognitive mechanisms underlying irritability in young people with ADHD, hypothesising that irritability would be associated with hot, but not cool, executive function impairments. METHODS: Our sample included 219 individuals with ADHD. A composite irritability score was derived extracting items from a parent interview, with scores ranging from 0 to 5. Associations were investigated using linear regression analyses, between irritability and four hot tasks measuring sensitivity to risk, risk-taking behaviour following reward or punishment, acceptance of reward delay and reaction to unfair behaviour from others, and two cool tasks measuring set-shifting and motor inhibition. RESULTS: As hypothesised, there were no significant associations between irritability and cool executive functions in those with ADHD; however, contrary to expectations, there was also no significant evidence that hot executive functions were associated with irritability. CONCLUSIONS: These results, in a large well characterised sample and using a comprehensive task battery, suggest that the variation in irritability in those with ADHD may not be associated with differences in hot or cool executive function performance.

Can facial emotion recognition be rapidly improved in children with disruptive behavior? A targeted and preventative early intervention study.

An impairment in recognizing distress is implicated in the development and severity of antisocial behavior. It has been hypothesized that a lack of attention to the eyes plays a role, but supporting evidence is limited. We developed a computerized training to improve emotion recognition in children and examined the role of eye gaze before and after training. Children referred into an intervention program to prevent antisocial outcomes completed an emotion recognition task with concurrent eye tracking. Those with emotion recognition impairments (n = 54, mean age: 8.72 years, 78% male) completed the training, while others (n = 38, mean age: 8.95 years, 84% male) continued with their usual interventions. Emotion recognition and eye gaze were reassessed in all children 8 weeks later. Impaired negative emotion recognition was significantly related to severity of behavioral problems at pretest. Children who completed the training significantly improved in emotion recognition; eye gaze did not contribute to impairment or improvement in emotion recognition. This study confirms the role of emotion recognition in severity of disruptive behavior and shows that a targeted intervention can quickly improve emotion impairments. The training works by improving children's ability to appraise emotional stimuli rather than by influencing their visual attention.

Negative parental emotional environment increases the association between childhood behavioral problems and impaired recognition of negative facial expressions.

Impaired facial emotion recognition is a transdiagnostic risk factor for a range of psychiatric disorders. Childhood behavioral difficulties and parental emotional environment have been independently associated with impaired emotion recognition; however, no study has examined the contribution of these factors in conjunction. We measured recognition of negative (sad, fear, anger), neutral, and happy facial expressions in 135 children aged 5-7 years referred by their teachers for behavioral problems. Parental emotional environment was assessed for parental expressed emotion (EE) - characterized by negative comments, reduced positive comments, low warmth, and negativity towards their child - using the 5-minute speech sample. Child behavioral problems were measured using the teacher-informant Strengths and Difficulties Questionnaire (SDQ). Child behavioral problems and parental EE were independently associated with impaired recognition of negative facial expressions specifically. An interactive effect revealed that the combination of both factors was associated with the greatest risk for impaired recognition of negative faces, and in particular sad facial expressions. No relationships emerged for the identification of happy facial expressions. This study furthers our understanding of multidimensional processes associated with the development of facial emotion recognition and supports the importance of early interventions that target this domain.

Atypical Facial Expressivity in Young Children with Problematic Peer Relationships.

Peer problems are frequently associated with difficulties in recognizing and appraising the emotions of others. It has been argued that facial responsiveness to others' emotions-or motor empathy-is a precursor of emotion processing and affective empathy. Although mimicry impairments have been observed in studies of young people with conduct problems, to our knowledge no study has examined facial responsiveness to others' expressions in young children and examined how this relates to peer relationship problems. Four- to 7-year-old children (n = 91) with or without teacher-reported peer relationship problems (Strength and Difficulties Questionnaire) viewed three dynamic film clips depicting a sad, happy, or scared child, while their spontaneous facial emotional responses were assessed using iMotions software that codes the movement of facial muscles. Children displayed facial expressivity that was congruent with the emotional expressions in the clips. Groups with and without peer problems did not differ in their responses to seeing a happy child. However, children with peer problems exhibited reduced or atypical facial emotional responses to the negative emotional clips. Decreased or atypical facial expressivity to negative emotions was also associated with severity of peer problems; atypical facial responsivity to sadness and reduced facial responsivity to fear predicted peer problems independently of one another. We conclude that reduced or atypical facial expressiveness in response to other children's dynamic facial expressions is associated with problematic peer relations in young children. The implications for early identification and interventions to support prosocial development are discussed.

Improving emotion recognition is associated with subsequent mental health and well-being in children with severe behavioural problems.

Impaired emotion recognition is a transdiagnostic risk factor for a range of psychiatric disorders. It has been argued that improving emotion recognition may lead to improvements in behaviour and mental health, but supportive evidence is limited. We assessed emotion recognition and mental health following a brief and targeted computerised emotion recognition training in children referred into an intervention program because of severe family adversity and behavioural problems (n = 62; aged 7-10). While all children continued to receive their usual interventions, only children impaired in emotion recognition (n = 40) received the emotion training. Teachers blind to whether or not children had received the training rated children's mental health problems before and 6 months after the training. Participants who received the emotion training significantly improved their recognition of negative and neutral facial expressions. Although both groups showed improved behaviour at follow-up, the reduction in behavioural problems was only significant in children who received the emotion training. Post-training emotion recognition scores predicted mental health problems 6 months later independently of initial emotion recognition ability and severity of behavioural problems. The results are consistent with the view that targeting emotion recognition can improve longer term functioning in individuals with disruptive behaviour, although further research using fully randomised designs is needed before causal conclusions can be drawn with confidence.

Infant emotional responses to challenge predict empathic behavior in toddlerhood.

Although emotional responses are theorized to be important in the development of empathy, findings regarding the prediction of early empathic behavior by infant behavioral and physiological responses are mixed. This study examined whether behavioral and physiological responses to mild emotional challenge (still face paradigm and car seat task) in 118 infants at age 6 months predicted empathic distress and empathic concern in response to an empathy-evoking task (i.e, experimenter's distress simulation) at age 20 months. Correlation analyses, corrected for sex and baseline levels of physiological arousal, showed that stronger physiological and behavioral responses to emotional challenge at age 6 months were positively related to observed empathic distress, but not empathic concern, at age 20 months. Linear regression analyses indicated that physiological and behavioral responses to challenge at 6 months independently predicted empathic distress at 20 months, which suggests an important role for both physiological and behavioral emotional responses in empathy development. In addition, curvilinear regression analyses showed quadratic associations between behavioral responses at 6 months, and empathic distress and empathic concern at 20 months, which indicates that moderate levels of behavioral responsivity predict the highest levels of empathic distress and empathic concern.

Associations between empathy, inhibitory control, and physical aggression in toddlerhood.

Impaired empathy has been associated with aggression in children, adolescents and adults, but results have been contradictory for the preschool period. Impaired inhibitory control also increases the risk of aggression, and possibly moderates empathy-aggression associations. The current study investigated whether empathy and inhibitory control are associated with aggression in toddlerhood. Furthermore, we aimed to clarify the role of inhibitory control in empathy and aggression, specifically, whether inhibitory control moderates the association between empathy and aggression. During a laboratory visit at age 30 months (N = 103), maternal reports of physical aggression were obtained and child inhibitory control was examined using a gift delay task. Empathy was examined by obtaining behavioral observations and recording physiological responses (heart rate response and respiratory sinus arrhythmia response) to an empathy-eliciting event (i.e., simulated distress). Reduced inhibitory control was associated with more aggression. Behavioral and physiological indicators of empathy were not associated with aggression. Hierarchical regression analyses revealed an interaction effect of heart rate response to distress simulation with inhibitory control in the prediction of aggression. Post hoc analyses indicated a negative association between heart rate response and aggression when inhibitory control was high, but a positive association was found in toddlers who demonstrated low inhibitory control. These results suggest that children are less aggressive when they have both high levels of empathy and inhibitory control. Therefore, both empathy and inhibition are important targets for interventions aiming to reduce or prevent aggression at a young age.

The nature and extent of emotion recognition and empathy impairments in children showing disruptive behaviour referred into a crime prevention programme.

Childhood disruptive behaviour has been linked to later antisocial and criminal behaviour. Emotion recognition and empathy impairments, thought to be caused by inattention to the eye region, are hypothesised to contribute to antisocial and criminal behaviour. This is the first study to simultaneously examine emotion recognition and empathy impairments, their relationship, and the mechanism behind these impairments, in children with disruptive behaviour. We hypothesised that children with disruptive behaviour would exhibit negative emotion recognition and cognitive and affective empathy impairments, but that these impairments would not be due to reduced attention to the eye region. We expected these emotion impairments to be driven by disruptive behaviour. We also expected a relationship between emotion recognition and cognitive empathy only. Ninety-two children with disruptive behaviour, who were participating in a police crime prevention programme and rated by their schoolteacher using the Strengths and Difficulties Questionnaire (DB; mean age 8.8 years, 80% male), took part. There was a comparison group of 58 typically developing children (TD; mean age 9.7 years, 78% male). All children completed emotion recognition and empathy tasks, both with concurrent eye tracking to assess social attention. Not only were DB children significantly impaired in negative emotion and neutral emotion recognition, and in cognitive and affective empathy compared to the TD children, but severity of disruptive behaviour also predicted intensity of emotion impairments. There were no differences in social attention to the eye region. Negative emotion recognition and empathy impairments are already present in an identifiable group of children displaying disruptive behaviour. These findings provide evidence to encourage the use of targeted interventions.

Recognition of Facial Emotion and Affective Prosody in Children at High Risk of Criminal Behavior.

OBJECTIVE: Emotion recognition is an important aspect of emotion processing, which is needed for appropriate social behavior and normal socialization. Previous studies in adults with antisocial personality disorder or psychopathy, in those convicted of criminal behavior, or in children with conduct disorder show impairments in negative emotion recognition. The present study investigated affective facial and prosody recognition in a sample of children at high risk of developing future criminal behavior. METHODS: Participants were 8- to 12-year-old children at high risk of developing criminal behavior (N=219, 83.1% boys) and typically developing controls (N=43, 72.1% boys). The high-risk children were recruited through an ongoing early intervention project of the city of Amsterdam, that focuses on the underage siblings or children of delinquents, and those failing to attend school. Facial and vocal recognition of happy, sad, angry, and fear was measured with the Facial Emotion Recognition (FER) test and the prosody test of the Amsterdam Neuropsychological Tasks (ANT), respectively. RESULTS: The high-risk group was significantly worse in facial affect recognition and had particular problems with fear and sadness recognition. No hostile attribution bias was found. The high-risk group did not differ from controls in affective prosody recognition but needed significantly more time to recognize emotions. CONCLUSIONS: The emotion-specific deficits found in forensic and clinical populations are already present in a sample of children at high risk of developing future criminal behavior. These findings help us understand a possible underlying mechanism of antisocial behavior that could provide directions for tailored interventions. (JINS, 2019, 25, 57-64).

Informants' ratings of activity level in infancy predict ADHD symptoms and diagnoses in childhood.

We tested the hypothesis that high activity levels in infancy would predict self-regulatory problems and later symptoms of attention deficit and hyperactivity disorder (ADHD) in a longitudinal study of British families (N = 321). Infants' activity levels were assessed at 6 months, using 3 informants' reports from the Infant Behavior Questionnaire (IBQ) and ActiGraphs during baseline, attention, and restraint tasks. At a mean of 33 months, the children were assessed on self-regulatory tasks; at a mean of 36 months, 3 informants reported symptoms of ADHD. At a mean of 7.0 years, the children were assessed on executive function tasks; 3 informants reported on the child's symptoms of ADHD; and diagnoses of disorder were obtained using the Preschool Age Psychiatric Assessment. Informants' reports of high activity levels at 6 months predicted ADHD symptoms in early childhood and diagnoses of ADHD with clinical impairment at age 7. The IBQ activity scale was also associated with the children's later performance on self-regulation tasks in early and middle childhood. Activity level in infancy reflects normal variation and is not a sign of psychopathology; however, these findings suggest that further study of the correlates of high activity level in infancy may help identify those children most at risk for disorder.

Prenatal risk and physical aggression during the first years of life: The gender-specific role of inhibitory control.

Prenatal risk and a lack of inhibitory control have consistently been related to the development of physical aggression in older children. This study examined whether inhibitory control mediated the relation between prenatal risk and aggression in infants and toddlers. The role of gender in this mediation model was also examined. The sample consisted of 161 mother-child dyads (83 boys). A prenatal cumulative risk score was created from a number of well-established risk factors including maternal psychopathology, substance use, and social and socioeconomic disadvantages. At 12 months, children performed an inhibitory control task. Physical aggression was assessed through maternal reports at 12 and 20 months of age. Results showed that higher prenatal risk was associated with more physical aggression. Inhibitory control mediated this association at both 12 and 20 months: higher prenatal risk was related to lower inhibitory control, which in turn led to higher aggression. At 20 months, gender moderated the mediation effect: the mediating role of inhibitory control was only found for girls. These results suggest that even before 2 years of age, inhibitory control is an important construct involved in the relation between prenatal risk and physical aggression.

Seven-year-olds' aggressive choices in a computer game can be predicted in infancy.

Concerns about the relationship between computer games and children's aggression have been expressed for decades, but it is not yet clear whether the content of such games evokes aggression or a prior history of aggression promotes children's interest in aggressive games. Two hundred and sixty-six 7-year-old children from a nationally representative longitudinal sample in the UK played a novel computer game (CAMGAME) in which the child's avatar encountered a series of social challenges that might evoke aggressive, prosocial or neutral behaviour. Aggressive choices during the game were predicted by well-known risk factors for aggressive conduct problems and the children's own early angry aggressiveness as infants. These findings suggest that children who are predisposed to aggression bring those tendencies to virtual as well as real environments.

Late, but not early, arriving younger siblings foster firstborns' understanding of second-order false belief.

This study examined the influence of younger siblings on children's understanding of second-order false belief. In a representative community sample of firstborn children (N=229) with a mean age of 7years (SD=4.58), false belief was assessed during a home visit using an adaptation of a well-established second-order false belief narrative enacted with Playmobil figures. Children's responses were coded to establish performance on second-order false belief questions. When controlling for verbal IQ and age, the existence of a younger sibling predicted a twofold advantage in children's second-order false belief performance, yet this was the case only for firstborns who experienced the arrival of a sibling after their second birthday. These findings provide a foundation for future research on family influences on social cognition.

Boys with Oppositional Defiant Disorder/Conduct Disorder Show Impaired Adaptation During Stress: An Executive Functioning Study.

Evidence for problems in executive functioning (EF) in children with oppositional defiant disorder/conduct disorder (ODD/CD) is mixed and the impact stress may have on EF is understudied. Working memory, sustained attention, inhibition and cognitive flexibility of boys with ODD/CD (n = 65) and non-clinical controls (n = 32) were examined under typical and stressful test conditions. Boys with ODD/CD showed impaired working memory under typical testing conditions, and impairments in working memory and sustained attention under stressful conditions. In contrast to controls, performance on sustained attention, cognitive flexibility and inhibition was less influenced by stress in boys with ODD/CD. These results suggest that boys with ODD/CD show impairments in adaptation to the environment whereas typically developing boys show adaptive changes in EF.

Executive Attention and Empathy-Related Responses in Boys with Oppositional Defiant Disorder or Conduct Disorder, With and Without Comorbid Anxiety Disorder.

This is a first study that investigated the relationships between executive attention-as an important aspect of emotion regulation-and state empathy and sympathy in ODD/CD boys with (N = 31) and without (N = 18) comorbid anxiety disorder (7-12 years). Empathic reactions were evoked using three sadness-inducing film clips. One clip was highly evocative involving a bear cub losing his mother, whilst two other clips were mildly evocative involving children in common childhood situations. Self-reports of empathy and sympathy were collected and executive attention was assessed with a performance task. Poor executive attention skills were associated with less empathy and sympathy, particularly in ODD/CD boys with anxiety and under conditions of a highly evocative stimulus. Our findings support the view that different mechanisms may be involved in empathy problems of ODD/CD children.

Affective empathy, cognitive empathy and social attention in children at high risk of criminal behaviour.

BACKGROUND: Empathy deficits are hypothesized to underlie impairments in social interaction exhibited by those who engage in antisocial behaviour. Social attention is an essential precursor to empathy; however, no studies have yet examined social attention in relation to cognitive and affective empathy in those exhibiting antisocial behaviour. METHODS: Participants were 8- to 12-year-old children at high risk of developing criminal behaviour (N = 114, 80.7% boys) and typically developing controls (N = 43, 72.1% boys). The high-risk children were recruited through an ongoing early identification and intervention project of the city of Amsterdam, focusing on the underage siblings or children of delinquents and those failing primary school. Video clips with neutral and emotional content (fear, happiness and pain) were shown, while heart rate (HR), skin conductance level (SCL) and skin conductance responses (SCRs) were recorded to measure affective empathy. Answers to questions about emotions in the clips were coded to measure cognitive empathy. Eye-tracking was used to evaluate visual scanning patterns towards social relevant cues (eyes and face) in the clips. RESULTS: The high-risk group did not differ from the control group in social attention and cognitive empathy, but showed reduced HR to pain and fear, and reduced SCL and SCRs to pain. CONCLUSIONS: Children at high risk of developing criminal behaviour show impaired affective empathy but unimpaired social attention and cognitive empathy. The implications for early identification and intervention studies with antisocial children are discussed.
