Altered neural response to rejection-related words in children exposed to maltreatment / Vanessa B. PUETZ in Journal of Child Psychology and Psychiatry, 57-10 (October 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-10 (October 2016) . - p.1165-1173 Titre : Altered neural response to rejection-related words in children exposed to maltreatment Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa B.

MCCRORY, Auteur Article en page(s) : p.1165-1173 Langues : Anglais (eng) Mots-clés : Child abuse  emotion regulation  fMRI  posttraumatic stress disorder  adolescence Index. décimale : PER Périodiques Résumé : Background Children exposed to maltreatment show neural sensitivity to facial cues signalling threat. However, little is known about how maltreatment influences the processing of social threat cues more broadly, and whether atypical processing of social threat cues relates to psychiatric risk. Methods Forty-one 10- to 14-year-old children underwent a social rejection-themed emotional Stroop task during functional magnetic resonance imaging: 21 children with a documented history of maltreatment (11 F) and 19 comparison children with no maltreatment history (11 F). Groups were matched on age, pubertal status, gender, IQ, socioeconomic status, ethnicity and reading ability. Classic colour Stroop stimuli were also administered in the same paradigm to investigate potential differences in general cognitive control. Results Compared with their peers, children who had experienced maltreatment showed reduced activation in the Rejection versus Neutral condition, across circuitry previously implicated in abuse-related posttraumatic stress disorder (PTSD), including the left anterior insula, extending into left ventrolateral prefrontal cortex/orbitofrontal cortex; left amygdala; left inferior parietal cortex (STS); and bilateral visual association cortex, encompassing the cuneus and lingual gyrus. No group differences in neural or behavioural responses were found for the classic colour Stroop conditions. Significant negative associations between activity in bilateral cuneus and STS during the rejection-themed Stroop and higher self-reported PTSD symptomatology, including dissociation, were observed in children exposed to maltreatment. Conclusion Our findings indicate a pattern of altered neural response to social rejection cues in maltreated children. Compared to their peers, these children displayed relative hypoactivation to rejection cues in regions previously associated with PTSD, potentially reflecting an avoidant coping response. It is suggested that such atypical processing of social threat may index latent vulnerability to future psychopathology in general and PTSD in particular.

Autobiographical memory as a latent vulnerability mechanism following childhood maltreatment: Association with future depression symptoms and prosocial behavior / Vanessa B. PUETZ in Development and Psychopathology, 33-4 (October 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-4 (October 2021) . - p.1300-1307 Titre : Autobiographical memory as a latent vulnerability mechanism following childhood maltreatment: Association with future depression symptoms and prosocial behavior Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa B.

Altered ABM and OGM have been linked with psychopathology and poorer social functioning. The present study investigated the association between altered ABM and subsequent socio-emotional functioning (measured two years later) in a sample of adolescents with (N = 20; maltreatment group, MT) and without (N = 17; non-MT group) documented childhood maltreatment histories. Method At baseline, adolescents (aged 12.6 ± 1.45 years) were administered the Autobiographical Memory Test to measure OGM. Participants also recalled specific ABMs in response to emotionally valenced cue words during functional MRI. Adolescents in both groups underwent assessments measuring depressive symptoms and prosocial behavior at both timepoints. Regression analyses were carried out to predict outcome measures at follow-up controlling for baseline levels. Results In the MT group, greater OGM at baseline significantly predicted reduced prosocial behavior at follow-up and showed a trend level association with elevated depressive symptoms. Patterns of altered ABM-related brain activity did not significantly predict future psycho-social functioning. Conclusions The current findings highlight the potential value of OGM as a cognitive mechanism that could be targeted to reduce risk of depression in adolescents with prior histories of maltreatment.

A neurocomputational investigation of reinforcement-based decision making as a candidate latent vulnerability mechanism in maltreated children / Mattia I. GERIN in Development and Psychopathology, 29-5 (December 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-5 (December 2017) . - p.1689-1705 Titre : A neurocomputational investigation of reinforcement-based decision making as a candidate latent vulnerability mechanism in maltreated children Type de document : Texte imprimé et/ou numérique Auteurs : Mattia I.

MCCRORY, Auteur Article en page(s) : p.1689-1705 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Alterations in reinforcement-based decision making may be associated with increased psychiatric vulnerability in children who have experienced maltreatment. A probabilistic passive avoidance task and a model-based functional magnetic resonance imaging analytic approach were implemented to assess the neurocomputational components underlying decision making: (a) reinforcement expectancies (the representation of the outcomes associated with a stimulus) and (b) prediction error signaling (the ability to detect the differences between expected and actual outcomes). There were three main findings. First, the maltreated group (n = 18; mean age = 13), relative to nonmaltreated peers (n = 19; mean age = 13), showed decreased activity during expected value processing in a widespread network commonly associated with reinforcement expectancies representation, including the striatum (especially the caudate), the orbitofrontal cortex, and medial temporal structures including the hippocampus and insula. Second, consistent with previously reported hyperresponsiveness to negative cues in the context of childhood abuse, the maltreated group showed increased prediction error signaling in the middle cingulate gyrus, somatosensory cortex, superior temporal gyrus, and thalamus. Third, the maltreated group showed increased activity in frontodorsal regions and in the putamen during expected value representation. These findings suggest that early adverse environments disrupt the development of decision-making processes, which in turn may compromise psychosocial functioning in ways that increase latent vulnerability to psychiatric disorder.

Sex differences in socioemotional functioning, attentional bias, and gray matter volume in maltreated children: A multilevel investigation / Philip A. KELLY in Development and Psychopathology, 27-4 (Part 2) (November 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-4 (Part 2) (November 2015) . - p.1591-1609 Titre : Sex differences in socioemotional functioning, attentional bias, and gray matter volume in maltreated children: A multilevel investigation Type de document : Texte imprimé et/ou numérique Auteurs : Philip A.

MCCRORY, Auteur Article en page(s) : p.1591-1609 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : While maltreatment is known to impact social and emotional functioning, threat processing, and neural structure, the potentially dimorphic influence of sex on these outcomes remains relatively understudied. We investigated sex differences across these domains in a large community sample of children aged 10 to 14 years (n = 122) comprising 62 children with verified maltreatment experience and 60 well-matched nonmaltreated peers. The maltreated group relative to the nonmaltreated comparison group exhibited poorer social and emotional functioning (more peer problems and heightened emotional reactivity). Cognitively, they displayed a pattern of attentional avoidance of threat in a visual dot-probe task. Similar patterns were observed in males and females in these domains. Reduced gray matter volume was found to characterize the maltreated group in the medial orbitofrontal cortex, bilateral middle temporal lobes, and bilateral supramarginal gyrus; sex differences were observed only in the supramarginal gyrus. In addition, a disordinal interaction between maltreatment exposure and sex was found in the postcentral gyrus. Finally, attentional avoidance to threat mediated the relationship between maltreatment and emotional reactivity, and medial orbitofrontal cortex gray matter volume mediated the relationship between maltreatment and peer functioning. Similar mediation patterns were observed across sexes. This study highlights the utility of combining multiple levels of analysis when studying the “latent vulnerability” engendered by childhood maltreatment and yields tentative findings regarding a neural basis of sex differences in long-term outcomes for maltreated children.
