SILVERS, Auteur ; Alex MARTIN, Auteur Année de publication : 2009 Article en page(s) : p.1735-1739 Langues : Anglais (eng) Mots-clés : Autism Asperger’s-syndrome Inner-speech Executive-function Problem-solving Language Index. décimale : PER Périodiques Résumé : Recent research indicates that individuals with autism do not effectively use inner speech during the completion of cognitive tasks. We used Articulatory Suppression (AS) to interfere with inner speech during completion of alternate items from the Tower of London (TOL). AS detrimentally affected TOL performance among typically developing (TD) adolescents (n = 25), but did not significantly diminish performance among adolescents with high functioning (IQ > 80) autism spectrum disorders (n = 28). Moreover, the TD group’s TOL performance under AS was indistinguishable from the autism group’s impaired baseline TOL performance. These findings suggest that diminished inner speech usage among individuals with high functioning autism spectrum disorders (relative to TD controls) may contribute to executive dysfunction associated with these disorders.

Diminished Sensitivity to Sad Facial Expressions in High Functioning Autism Spectrum Disorders is Associated with Symptomatology and Adaptive Functioning / Gregory L. WALLACE in Journal of Autism and Developmental Disorders, 41-11 (November 2011)

We compared FER accuracy and perceptual sensitivity (from neutral to full expression) between 42 adolescents with high functioning (IQ > 80) ASD and 31 typically developing adolescents (matched on age, IQ, sex ratio) across six basic emotions and examined links between FER and symptomatology/adaptive functioning within the ASD group. Adolescents with ASD required more intense facial expressions for accurate emotion identification. Controlling for this overall group difference revealed particularly diminished sensitivity to sad facial expressions in ASD, which was uniquely correlated with ratings of autism-related behavior and adaptive functioning.

Early life adversity is associated with greater similarity in neural representations of ambiguous and threatening stimuli / Natalie M. SARAGOSA-HARRIS in Development and Psychopathology, 37-2 (May 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-2 (May 2025) . - p.802-814 Titre : Early life adversity is associated with greater similarity in neural representations of ambiguous and threatening stimuli Type de document : Texte imprimé et/ou numérique Auteurs : Natalie M.

SILVERS, Auteur Article en page(s) : p.802-814 Langues : Anglais (eng) Mots-clés : ambiguity tolerance  early life adversity  representational similarity analysis  threat hypervigilance  valence bias Index. décimale : PER Périodiques Résumé : Exposure to early life adversity (ELA) is hypothesized to sensitize threat-responsive neural circuitry. This may lead individuals to overestimate threat in the face of ambiguity, a cognitive-behavioral phenotype linked to poor mental health. The tendency to process ambiguity as threatening may stem from difficulty distinguishing between ambiguous and threatening stimuli. However, it is unknown how exposure to ELA relates to neural representations of ambiguous and threatening stimuli, or how processing of ambiguity following ELA relates to psychosocial functioning. The current fMRI study examined multivariate representations of threatening and ambiguous social cues in 41 emerging adults (aged 18 to 19 years). Using representational similarity analysis, we assessed neural representations of ambiguous and threatening images within affective neural circuitry and tested whether similarity in these representations varied by ELA exposure. Greater exposure to ELA was associated with greater similarity in neural representations of ambiguous and threatening images. Moreover, individual differences in processing ambiguity related to global functioning, an association that varied as a function of ELA. By evidencing reduced neural differentiation between ambiguous and threatening cues in ELA-exposed emerging adults and linking behavioral responses to ambiguity to psychosocial wellbeing, these findings have important implications for future intervention work in at-risk, ELA-exposed populations.

Adolescence is associated with increasing approach behavior (e.g., novelty-seeking, risk-taking) but often also coincides with emerging internalizing symptoms, which are characterized by heightened avoidance behavior. Peaking engagement of the nucleus accumbens (NAcc) during adolescence, often studied in reward paradigms, may also relate to threat mechanisms of adolescent psychopathology.Methods:47 typically developing adolescents (9.9-22.9 years) completed an aversive learning task during functional magnetic resonance imaging, wherein visual cues were paired with an aversive sound or no sound. Task blocks involved an escapable aversively reinforced stimulus (CS+r), the same stimulus without reinforcement (CS+nr), or a stimulus that was never reinforced (CS?). Parent-reported internalizing symptoms were measured using Revised Child Anxiety and Depression Scales.Results:Functional connectivity between the NAcc and amygdala differentiated the stimuli, such that connectivity increased for the CS+r (p = .023) but not for the CS+nr and CS?. Adolescents with greater internalizing symptoms demonstrated greater positive functional connectivity for the CS? (p = .041).Conclusions:Adolescents show heightened NAcc-amygdala functional connectivity during escape from threat. Higher anxiety and depression symptoms are associated with elevated NAcc-amygdala connectivity during safety, which may reflect poor safety versus threat discrimination.

Research Review: The neuroscience of emerging adulthood - reward, ambiguity, and social support as building blocks of mental health / Jennifer A. SILVERS in Journal of Child Psychology and Psychiatry, 64-7 (July 2023)

SILVERS, Auteur ; Tara S. PERIS, Auteur Article en page(s) : p.989-997 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BackgroundThe interval between adolescence and adulthood, 'emerging adulthood' (EA), lays the foundation for lifelong health and well-being. To date, there exist little empirical data - particularly in the neurobiological domain - to establish markers of risk and resilience during the transition to adulthood. This gap in the literature is concerning given the numerous forms of psychiatric illness that emerge or worsen during this period.MethodsIn this review, we focus on two strands of research with distinct importance for EA: reward sensitivity, and tolerance of ambiguity. We begin by placing these domains in a framework that considers the unique developmental goals of EA and then synthesize emerging neurobiological research on how these domains develop during EA. We then consider their role in common mental health problems that occur during this interval as well as how social support may moderate outcomes. Finally, we offer recommendations for advancing research to understand developmental process and outcomes in EA.Findings and conclusionsFew longitudinal studies specifically address emerging adult development and the milestones that characterize this interval. Data on neurobiological development are similarly sparse. Understanding neurobiological development during this window and its links to key adjustment outcomes is crucial for optimizing outcomes.
