Titre : Does reward processing moderate or mediate the link between childhood adversity and psychopathology: A longitudinal study Type de document : Texte imprimé et/ou numérique Auteurs : Lindsay C. HANFORD, Auteur ; Steven W. KASPAREK, Auteur ; Liliana J. LENGUA, Auteur ; Katie A. MCLAUGHLIN, Auteur ; Margaret A. SHERIDAN, Auteur Article en page(s) : p.2338-2351 Mots-clés : depression deprivation externalizing reward processing threat Index. décimale : PER Périodiques Résumé : Childhood adversity is common and associated with elevated risk for transdiagnostic psychopathology. Reward processing has been implicated in the link between adversity and psychopathology, but whether it serves as a mediator or moderator is unclear. This study examined whether alterations in behavioral and neural reward processing function as a mechanism or moderator of psychopathology outcomes following adversity experiences, including threat (i.e., trauma) and deprivation. A longitudinal community sample of 10?15-year-old youths was assessed across two waves (Wave 1: n = 228; Wave 2: n = 206). Wave 1 assessed adverse experiences, psychopathology symptoms, reward processing on a monetary incentive delay task, and resting-state fMRI. At Wave 2, psychopathology symptoms were reassessed. Greater threat experiences were associated with blunted behavioral reward sensitivity, which, in turn, predicted increases in depression symptoms over time and mediated the prospective association between threat and depression symptoms. In contrast, reward sensitivity moderated the association between deprivation experiences and prospective externalizing symptoms such that the positive association of deprivation with increasing externalizing symptoms was absent for children with high levels of reward sensitivity.

Titre : Oscillatory rhythm of reward: anticipation and processing of rewards in children with and without autism Type de document : Texte imprimé et/ou numérique Auteurs : K. K. STAVROPOULOS, Auteur ; Leslie J. CARVER, Auteur Article en page(s) : 4p. Langues : Anglais (eng) Mots-clés : Alpha asymmetry Autism spectrum disorder Reward processing Social stimuli Theta Index. décimale : PER Périodiques Résumé : Background: Autism spectrum disorder (ASD) is a complex neurodevelopmental condition, and multiple theories have emerged concerning core social deficits. While the social motivation hypothesis proposes that deficits in the social reward system cause individuals with ASD to engage less in social interaction, the overly intense world hypothesis (sensory over-responsivity) proposes that individuals with ASD find stimuli to be too intense and may have hypersensitivity to social interaction, leading them to avoid these interactions. Methods: EEG was recorded during reward anticipation and reward processing. Reward anticipation was measured using alpha asymmetry, and post-feedback theta was utilized to measure reward processing. Additionally, we calculated post-feedback alpha suppression to measure attention and salience. Participants were 6- to 8-year-olds with (N = 20) and without (N = 23) ASD. Results: Children with ASD showed more left-dominant alpha suppression when anticipating rewards accompanied by nonsocial stimuli compared to social stimuli. During reward processing, children with ASD had less theta activity than typically developing (TD) children. Alpha activity after feedback showed the opposite pattern: children with ASD had greater alpha suppression than TD children. Significant correlations were observed between behavioral measures of autism severity and EEG activity in both the reward anticipation and reward processing time periods. Conclusions: The findings provide evidence that children with ASD have greater approach motivation prior to nonsocial (compared to social) stimuli. Results after feedback suggest that children with ASD evidence less robust activity thought to reflect evaluation and processing of rewards (e.g., theta) compared to TD children. However, children with ASD evidence greater alpha suppression after feedback compared to TD children. We hypothesize that post-feedback alpha suppression reflects general cognitive engagement-which suggests that children with ASD may experience feedback as overly intense. Taken together, these results suggest that aspects of both the social motivation hypothesis and the overly intense world hypothesis may be occurring simultaneously.

Titre : Children with ADHD symptoms show decreased activity in ventral striatum during the anticipation of reward, irrespective of ADHD diagnosis Type de document : Texte imprimé et/ou numérique Auteurs : Branko M. VAN HULST, Auteur ; Patrick DE ZEEUW, Auteur ; Dienke J. BOS, Auteur ; Yvonne RIJKS, Auteur ; Sebastiaan F. W. NEGGERS, Auteur ; Sarah DURSTON, Auteur Année de publication : 2017 Article en page(s) : p.206-214 Langues : Anglais (eng) Mots-clés : Attention-deficit/hyperactivity disorder fMRI reward processing striatum trans-diagnostic mechanisms reward anticipation autism spectrum disorder Index. décimale : PER Périodiques Résumé : Background Changes in reward processing are thought to be involved in the etiology of attention-deficit/hyperactivity disorder (ADHD), as well as other developmental disorders. In addition, different forms of therapy for ADHD rely on reinforcement principles. As such, improved understanding of reward processing in ADHD could eventually lead to more effective treatment options. However, differences in reward processing may not be specific to ADHD, but may be a trans-diagnostic feature of disorders that involve ADHD-like symptoms. Methods In this event-related fMRI study, we used a child-friendly version of the monetary incentive delay task to assess performance and brain activity during reward anticipation. Also, we collected questionnaire data to assess reward sensitivity in daily life. For final analyses, data were available for 27 typically developing children, 24 children with ADHD, and 25 children with an autism spectrum disorder (ASD) and ADHD symptoms. Results We found decreased activity in ventral striatum during anticipation of reward in children with ADHD symptoms, both for children with ADHD as their primary diagnosis and in children with autism spectrum disorder and ADHD symptoms. We found that higher parent-rated sensitivity to reward was associated with greater anticipatory activity in ventral striatum for children with ADHD symptoms. In contrast, there was no relationship between the degree of ADHD symptoms and activity in ventral striatum. Conclusions We provide evidence of biological and behavioral differences in reward sensitivity in children with ADHD symptoms, regardless of their primary diagnosis. Ultimately, a dimensional brain-behavior model of reward sensitivity in children with symptoms of ADHD may be useful to refine treatment options dependent on reward processing.

CROWLEY, Auteur Article en page(s) : p.1-10 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD) Reward processing Theta oscillations Event-related spectral analysis Inter-trial phase coherence Index. décimale : PER Périodiques Résumé : Impairment in prediction and appreciation for choice outcomes could contribute to several core symptoms of ASD. We examined electroencephalography (EEG) oscillations in 27 youth and young adults diagnosed with autism spectrum disorder (ASD) and 22 IQ-matched neurotypical controls while they performed a chance-based reward prediction task. We re-analyzed our previously published ERP data (Larson et al., 2011) and examined theta band oscillations (4–8 Hz) at frontal midline sites, within a timing window that overlaps with the feedback-related negativity (FRN). We focused on event-related changes after presentation of feedback for reward (WIN) and punitive (LOSE) outcomes, both for spectral power and inter-trial phase coherence. Results In our reward prediction task, for both groups, medial frontal theta power and phase coherence were greater following LOSE compared to WIN feedback. However, compared to controls, inter-trial coherence of medial frontal theta was significantly lower overall (across both feedback types) for individuals with ASD. Our results indicate that while individuals with ASD are sensitive to the valence of reward feedback, comparable to their neurotypical peers, they have reduced synchronization of medial frontal theta activity during feedback processing. This finding is consistent with previous studies showing neural variability in ASD and suggest that the processes underlying decision-making and reinforcement learning may be atypical and less efficient in ASD.

Titre : Reward Devaluation in Autistic Children and Adolescents with Complex Needs: A Feasibility Study Type de document : Texte imprimé et/ou numérique Auteurs : Anna LAMBRECHTS, Auteur ; Jennifer L. COOK, Auteur ; Elliot A. LUDVIG, Auteur ; Eduardo ALONSO, Auteur ; Sophie ANNS, Auteur ; Maddison TAYLOR, Auteur ; Sebastian B GAIGG, Auteur Article en page(s) : p.1915-1928 Langues : Anglais (eng) Mots-clés : autism complex needs devaluation intellectual disability reward processing Index. décimale : PER Périodiques Résumé : Rewards act as a motivator for positive behavior and learning. Although compounding evidence indicates that reward processing operates differently in autistic individuals who do not have co-occurring learning disabilities, little is known about individuals who have such difficulties or other complex needs. This study aimed first to assess the feasibility of using an adapted reward devaluation paradigm to examine basic reward processes in this underrepresented population, and second to investigate whether autistic children and adolescents with complex needs would show dynamic behavioral changes in response to changes in the motivational value of a reward. Twenty-seven autistic children and adolescents with complex needs and 20 typically developing 5-year-old children took part in the study. Participants were presented with two visual cues on a touchscreen laptop, which triggered the delivery of a video, music, or physical reward. One of the rewards was then presented in abundance to decrease its motivational value. Participants showed decreased interest in the video and music rewards after devaluation. The experimental setup was found to be suitable to test individuals with complex needs, although recommendations are made for the use of physical rewards. The results suggest that autistic participants with complex needs demonstrate goal-directed behavior and that it is feasible to develop experimental paradigms that can shed important light on learning processes that are fundamental to many education and intervention strategies for this population. Autism Res 2020, 13: 1915-1928. © 2020 The Authors. Autism Research published by International Society for Autism Research and Wiley Periodicals LLC. LAY SUMMARY: We adapted an experimental task to conduct research with autistic children and adolescents with complex needs, who remain grossly underrepresented in autism research. We found that once a reward was presented in great quantity, participants were less motivated to obtain it, showing that they adapted their behavior to changes in the value of that reward. This is an important finding to help promote learning and design better interventions for this population.
