Delay discounting of reward in ADHD: application in young children / Vanessa B. WILSON in Journal of Child Psychology and Psychiatry, 52-3 (March 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-3 (March 2011) . - p.256-264 Titre : Delay discounting of reward in ADHD: application in young children Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa B. WILSON, Auteur ; Suzanne H. MITCHELL, Auteur ; Erica D. MUSSER, Auteur ; Colleen F. SCHMITT, Auteur ; Joel T. NIGG, Auteur Année de publication : 2011 Article en page(s) : p.256-264 Langues : Anglais (eng) Mots-clés : Impulsivity  delay discounting  ADHD Index. décimale : PER Périodiques Résumé : Background:  A key underlying process that may contribute to attention-deficit/hyperactivity disorder (ADHD) involves alterations in reward evaluation, including assessing the relative value of immediate over delayed rewards. This study examines whether children with ADHD discount the value of delayed rewards to a greater degree than typically developing children using a delay discounting task. Methods:  Children aged 7–9 years diagnosed with ADHD and controls completed a task in which they chose between a hypothetical $10 available after a delay (7, 30, 90 and 180 days) versus various amounts available immediately. Results:  ADHD participants discounted more steeply than controls. However, this effect did not survive covarying of IQ. Conclusions:  ADHD is associated with a steeper delay gradient when contemplating hypothetical later rewards, but not independently of IQ. The interplay of cognitive processing and IQ with reward evaluation in ADHD requires further exploration.

ADHD-related sex differences in fronto-subcortical intrinsic functional connectivity and associations with delay discounting / K. S. ROSCH in Journal of Neurodevelopmental Disorders, 10-1 (December 2018)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 10-1 (December 2018) . - 34 p. Titre : ADHD-related sex differences in fronto-subcortical intrinsic functional connectivity and associations with delay discounting Type de document : Texte imprimé et/ou numérique Auteurs : K. S. ROSCH, Auteur ; S. H. MOSTOFSKY, Auteur ; M. B. NEBEL, Auteur Année de publication : 2018 Article en page(s) : 34 p. Langues : Anglais (eng) Mots-clés : Adhd  Delay discounting  Functional connectivity  Ica  Resting-state  Reward  Temporal discounting  fMRI Index. décimale : PER Périodiques Résumé : BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is associated with atypical fronto-subcortical neural circuitry and heightened delay discounting, or a stronger preference for smaller, immediate rewards over larger, delayed rewards. Recent evidence of ADHD-related sex differences in brain structure and function suggests anomalies in fronto-subcortical circuitry may differ among girls and boys with ADHD. The current study examined whether the functional connectivity (FC) within fronto-subcortical neural circuitry differs among girls and boys with ADHD compared to same-sex typically developing (TD) controls and relates to delay discounting. METHODS: Participants include 8-12-year-old children with ADHD (n = 72, 20 girls) and TD controls (n = 75, 21 girls). Fronto-subcortical regions of interest were functionally defined by applying independent component analysis to resting-state fMRI data. Intrinsic FC between subcortical components, including the striatum and amygdala, and prefrontal components, including ventromedial prefrontal cortex (vmPFC), anterior cingulate cortex (ACC), and anterior dorsolateral prefrontal cortex (dlPFC), was compared across diagnostic groups overall and within sex. Correlations between intrinsic FC of the six fronto-subcortical pairs and delay discounting were also examined. RESULTS: Both girls and boys with ADHD show atypical FC between vmPFC and subcortical regions including the striatum (stronger positive FC in ADHD) and amygdala (weaker negative FC in ADHD), with the greatest diagnostic effects among girls. In addition, girls with ADHD show atypical intrinsic FC between the striatum and dlPFC components, including stronger positive FC with ACC and stronger negative FC with dlPFC. Further, girls but not boys, with ADHD, show heightened real-time delay discounting. Brain-behavior correlations suggest (1) stronger negative FC between the striatal and dlPFC components correlated with greater money delay discounting across all participants and (2) stronger FC between the amygdala with both the dlPFC and ACC components was differentially related to heightened real-time discounting among girls and boys with and without ADHD. CONCLUSIONS: Our findings suggest fronto-subcortical functional networks are affected in children with ADHD, particularly girls, and relate to delay discounting. These results also provide preliminary evidence of greater disruptions in fronto-subcortical FC among girls with ADHD that is not due to elevated inattention symptom severity, intellectual reasoning ability, age, or head motion.

Exposure to maternal depressive symptoms and growth in adolescent substance use: The mediating role of delay discounting / Julia W. FELTON in Development and Psychopathology, 33-4 (October 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-4 (October 2021) . - p.1279-1289 Titre : Exposure to maternal depressive symptoms and growth in adolescent substance use: The mediating role of delay discounting Type de document : Texte imprimé et/ou numérique Auteurs : Julia W.

Rates of delay discounting, or the tendency to select smaller rewards that are immediately available relative to larger, but delayed rewards, are also associated with steeper increases in substance use among youth. Moreover, recent research suggests that early unstable environments may reinforce youths’ propensity towards opportunistic decision making and delay discounting specifically. The current prospective, longitudinal study examined links between maternal depressive symptoms, adolescent delay discounting, and subsequent substance use. Participants included 247 adolescents and their mothers who were assessed annually over a 6-year period (from ages 13 to 19 years). Results supported a small but significant mediation effect. Specifically, maternal depressive symptoms predicted increases in adolescent delay discounting, which, in turn, predicted steeper increases in adolescent substance use over time. Thus, youth decision making may represent a mechanism linking maternal depression and adolescent risk behaviors. Findings indicate the potential for interventions targeting parental psychopathology to prevent subsequent adolescent substance use.

Longitudinal pathways linking family risk, neural risk processing, delay discounting, and adolescent substance use / J. KIM-SPOON in Journal of Child Psychology and Psychiatry, 60-6 (June 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-6 (June 2019) . - p.655-664 Titre : Longitudinal pathways linking family risk, neural risk processing, delay discounting, and adolescent substance use Type de document : Texte imprimé et/ou numérique Auteurs : J.

Yet, little is known about developmental pathways through which family risk factors are related to neural processing of risk during decision making, ultimately contributing to health risk behaviors. Using a longitudinal design, we tested whether neural risk processing, as affected by family multi-risk index, predicted delay discounting and substance use. METHOD: One hundred and fifty-seven adolescents (aged 13-14 years at Time 1, 52% male) were assessed annually three times. Family multi-risk index was measured by socioeconomic adversity, household chaos, and family risk-taking behaviors. Delay discounting was assessed by a computerized task, substance use by questionnaire data, and risk-related neural processing by blood-oxygen-level-dependent (BOLD) responses in the amygdala during a lottery choice task. RESULTS: Family multi-risk index at Time 1 was related to adolescent substance use at Time 3 (after controlling for baseline substance use) indirectly through heightened amygdala sensitivity to risks and greater delay discounting. CONCLUSIONS: Our results elucidate the crucial role of neural risk processing in the processes linking family multi-risk index and the development of substance use. Furthermore, risk-related amygdala activation and delay discounting are important targets in the prevention and treatment of substance use among adolescents growing up in high-risk family environments.

Social and delay discounting in autism spectrum disorder / Katherine RICE WARNELL in Autism Research, 12-6 (June 2019)  

Public ISBD [article]  inAutism Research > 12-6 (June 2019) . - p.870-877 Titre : Social and delay discounting in autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Katherine RICE WARNELL, Auteur ; S. MANISCALCO, Auteur ; S. BAKER, Auteur ; R. YI, Auteur ; E. REDCAY, Auteur Année de publication : 2019 Article en page(s) : p.870-877 Langues : Anglais (eng) Mots-clés : autism  delay discounting  perspective taking  reward  social discounting  temporal discounting Index. décimale : PER Périodiques Résumé : Current literature is divided over whether and how processes such as perspective taking and reward sensitivity differ between individuals with autism spectrum disorder (ASD) versus neurotypical individuals. Discounting tasks may provide novel insight into how these processes operate. In delay discounting tasks, participants choose between smaller immediate rewards and larger delayed rewards, and in social discounting tasks, participants choose between a smaller monetary rewards for themselves versus a larger reward for partners of varied social distance (e.g., a close friend vs. an acquaintance). Delay and social discounting tasks thus implicitly measure the subjective value of rewards given to one's future self and to others, capturing constructs such as perspective taking, reward processing, and social closeness, all of which have been discussed as core cognitive mechanisms underlying ASD. Despite extensive research on discounting in other clinical populations, few studies have examined delay discounting in ASD and no research has examined social discounting in ASD. The goal of the current study was to assess delay and social discounting for monetary rewards in a single sample of adolescents and adults with ASD compared to a matched neurotypical sample. Overall, adults and adolescents with ASD valued both future rewards and rewards given to others less than their typical counterparts did, but rates of discounting were not significantly correlated across temporal and social domains. These results extend an important behavioral paradigm for understanding both perspective taking and reward processing to autism. Autism Res 2019, 12: 870-877. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Discounting tasks-which experimentally measure the subjective value of different rewards-have been used with a variety of clinical populations, but are underexplored in ASD. We found that compared to neurotypical individuals, individuals with ASD showed diminished subjective value for future rewards (compared to immediate rewards) and rewards for others (compared to rewards for self). This finding has implications for understanding perspective taking, reward processing, and social closeness in ASD.
