Can reactivity and regulation in infancy predict inattentive and hyperactive/impulsive behavior in 3-year-olds? / Matilda A. FRICK in Development and Psychopathology, 31-2 (May 2019)

BROCKI, Auteur Article en page(s) : p.619-629 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : A need to identify early infant markers of later occurring inattentive and hyperactive/impulsive behaviors has come to the fore in the current attention-deficit/hyperactivity disorder literature. The purpose of such studies is to identify driving mechanisms that could enable early detection of attention-deficit/hyperactivity disorder liability and thus facilitate early intervention. Here we study independent and interactive effects of cognitive regulation (inhibition and sustained attention), temperament (reactive and regulatory aspects), and maternal sensitivity (as external regulation) in a sample of 112 typically developing 10-month-old infants (59 boys, 52.7%), in relation to inattentive and hyperactive/impulsive behavior at 3 years. The results showed that infant temperamental regulation and maternal sensitivity made independent contributions to both inattention and hyperactivity/impulsivity, in that higher levels of temperamental regulation and maternal sensitivity were related to less inattentive and hyperactive/impulsive behavior. In addition, the temperamental factor positive affectivity/surgency made a significant contribution to later hyperactivity/impulsivity, in that higher levels of positive affectivity/surgency were related to more hyperactive/impulsive behavior. No interaction effects were found. Our findings suggest temperament and parental regulation as potential and independent markers of later inattentive and hyperactive/impulsive behavior.

Challenges with shifting, regardless of disengagement: attention mechanisms and eye movements in Williams syndrome / Astrid HALLMAN in Journal of Neurodevelopmental Disorders, 17 (2025)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 17 (2025) Titre : Challenges with shifting, regardless of disengagement: attention mechanisms and eye movements in Williams syndrome Type de document : texte imprimé Auteurs : Astrid HALLMAN, Auteur ; Charlotte WILLFORS, Auteur ; Christine FAWCETT, Auteur ; Matilda A. FRICK, Auteur ; Ann NORDGREN, Auteur ; Johan Lundin KLEBERG, Auteur Langues : Anglais (eng) Mots-clés : Eye tracking  Intellectual disability  Orienting attention  Phasic alerting effect  Pupil dilation  Shifting attention  Visual disengagement  Williams syndrome  in accordance with the Declaration of Helsinki and received approval from the  Regional Ethics Committee of Stockholm, Sweden (dnr 2018/1218-31 with subsequent  amendments). Informed consents were collected from the participants and/or their  legal guardians. Informed assent was obtained from all participants who were able  to assent.

Index. décimale : PER Périodiques Résumé : BACKGROUND: People with Williams syndrome (WS) face challenges in various areas of cognitive processing, including attention. Previous studies suggest that these challenges are particularly pronounced when disengagement of attention from a previously attended stimulus is required, as compared to shifting attention without the need to disengage. Difficulties with attention could in turn be implicated in several of the behavioral characteristics of WS. Here, disengagement and shifting of visual attention, together with pupil dilation, were independently assessed in one of the largest eye-tracking studies of WS to date. METHODS: We investigated shifting, disengagement, and the effects of auditory alerting cues on pupil dilation in WS individuals (n = 45, age range = 9–58 years), non-WS individuals with intellectual disability (ID) (n = 36, age range = 6–59 years), and typically developed (TD) infants (n = 32, age range = 6–7 months), children and adults (n = 31, age range = 9–60 years), using a modified gap-overlap task. Data were analyzed using linear mixed-effect models (LMMs). RESULTS: Individuals with WS were less likely to shift their attention to upcoming targets than TD individuals (all ages), but more likely than the ID group to do so. When they did shift attention, participants with WS and ID were slower to initiate a gaze shift than TD participants regardless of whether disengagement was needed. In the WS group, failure to shift attention was strongly predicted by higher arousal (pupil dilation), which was induced by auditory alerting cues. CONCLUSIONS: Contrasting with previous theories of attention in WS, we found no evidence for a specific challenge in disengaging attention. Instead, our results point to a more general challenge in shifting attention. Reduced attention shifting in WS may be partly explained by atypical arousal regulation. These results contribute to our understanding of the WS phenotype. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1186/s11689-025-09639-z.

Increased pupil dilation to happy faces in children with hyperactive/impulsive symptoms of ADHD / Johan LUNDIN KLEBERG in Development and Psychopathology, 33-3 (August 2021)

BROCKI, Auteur Article en page(s) : p.767-777 Langues : Anglais (eng) Mots-clés : arousal  attention-deficit/hyperactivity disorder (ADHD)  face perception  positive emotionality  pupil dilation Index. décimale : PER Périodiques Résumé : Attention-deficit/hyperactivity disorder (ADHD) is associated with disrupted emotional processes including impaired regulation of approach behavior and positive affect, irritability, and anger. Enhanced reactivity to emotional cues may be an underlying process. Pupil dilation is an indirect index of arousal, modulated by the autonomic nervous system and activity in the locus coeruleus-noradrenergic system. In the current study, pupil dilation was recorded while 8- to 12- year old children (n = 71, 26 with a diagnosis of ADHD and 45 typically developing), viewed images of emotional faces. Parent-rated hyperactive/impulsive symptoms were uniquely linked to higher pupil dilation to happy, but not fearful, angry, or neutral faces. This was not explained by comorbid externalizing symptoms. Together, these results suggest that hyperactive/impulsive symptoms are associated with hyperresponsiveness to approach-related emotional cues across a wide range of symptom severity.

Attention to others' eyes is crucial for social understanding. Orienting to, and from other?s eyes was studied in WS (n 37, mean age 23, age range 9-53). The WS group was compared to a typically developing comparison participants (n 167) in stratified age groups from infancy to adulthood. Typically developing children and adults were quicker and more likely to orient to eyes than the mouth. This bias was absent in WS. The WS group had reduced peak saccadic velocities, indicating hypo-arousal. The current study indicates reduced orienting to others' eyes in WS, which may affect social interaction skills.
