Brain activity and infant attachment history in young men during loss and reward processing / Karina QUEVEDO in Development and Psychopathology, 29-2 (May 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-2 (May 2017) . - p.465-476 Titre : Brain activity and infant attachment history in young men during loss and reward processing Type de document : Texte imprimé et/ou numérique Auteurs : Karina QUEVEDO, Auteur ; Theodore E. A. WATERS, Auteur ; Hannah SCOTT, Auteur ; Glenn I. ROISMAN, Auteur ; Daniel S. SHAW, Auteur ; Erika E. FORBES, Auteur Article en page(s) : p.465-476 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : There is now ample evidence that the quality of early attachment experiences shapes expectations for supportive and responsive care and ultimately serves to scaffold adaptation to the salient tasks of development. Nonetheless, few studies have identified neural mechanisms that might give rise to these associations. Using a moderately large sample of low-income male participants recruited during infancy (N = 171), we studied the predictive significance of attachment insecurity and disorganization at age 18 months (as measured in the Strange Situation Procedure) for patterns of neural activation to reward and loss at age 20 years (assessed during a reward-based task as part of a functional magnetic resonance imaging scan). Results indicated that individuals with a history of insecure attachment showed hyperactivity in (a) reward- and emotion-related (e.g., basal ganglia and amygdala) structures and (b) emotion regulation and self-referential processing (cortical midline structures) in response to positive and negative outcomes (and anticipation of those outcomes). Further, the neural activation of individuals with a history of disorganized attachment suggested that they had greater emotional reactivity in anticipation of reward and employed greater cognitive control when negative outcomes were encountered. Overall, results suggest that the quality of early attachments has lasting impacts on brain function and reward processing.

Risk-taking and sensation-seeking propensity in postinstitutionalized early adolescents / Michelle M. LOMAN in Journal of Child Psychology and Psychiatry, 55-10 (October 2014)

Although these problems have been well described, the related adolescent behaviors of risk-taking and sensation-seeking have not yet been explored in this population. This study examined risk-taking and sensation-seeking propensity, and associations with conduct problems and depressive symptoms, in early adolescents who were adopted as young children from institutional care. Methods Risk-taking and sensation-seeking propensities of 12- and 13-year-old postinstitutionalized (PI; n = 54) adolescents were compared with two groups: youth who were internationally adopted early from foster care (PFC; n = 44) and nonadopted youth (NA; n = 58). Participants were recruited to equally represent pre/early- and mid/late-pubertal stages within each group. Participants completed the youth version of the Balloon Analogue Risk Task (Lejuez et al., ) and the Sensation-Seeking Scale for Children (Russo et al., ). Parents completed clinical ratings of participants' conduct problems and depressive symptoms.

The neurobiology of self-processing in abused depressed adolescents / Karina QUEVEDO in Development and Psychopathology, 29-3 (August 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-3 (August 2017) . - p.1057-1073 Titre : The neurobiology of self-processing in abused depressed adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Karina QUEVEDO, Auteur ; Rowena NG, Auteur ; Hannah SCOTT, Auteur ; Garry SMYDA, Auteur ; Jennifer H. PFEIFER, Auteur ; Sandra MALONE, Auteur Article en page(s) : p.1057-1073 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Maltreatment is associated with chronic depression, high negative self-attributions, and lifetime psychopathology. Adolescence is a sensitive period for the formation of self-concept. Identifying neurobiomarkers of self-processing in depressed adolescents with and without maltreatment may parse the effects of trauma and depression on self-development and chronic psychopathology. Depressed adolescents (n = 86) maltreated due to omission (DO, n = 13) or commission (DCM, n = 28) or without maltreatment (DC, n = 45), and HCs (HC, n = 37) appraised positive and negative self-descriptors in the scanner. DCM and DO showed hypoactivity in the dorsal anterior cingulate cortex (dACC) while processing positive versus negative self-descriptors compared to DC youth, who in turn showed reduced dACC recruitment versus HC. HC youth showed the highest activation in the dACC and striatum during positive self-descriptors; these regions showed a linear decline in activity across DC, DO, and DCM. Low dACC activity to positive versus negative self-descriptors was linked to inadequate coregulation of children's emotions by parents. Negative self-cognitions prevalent in DCM and DO adolescents may be perpetuated by activity in the dACC and striatum. Reduced activation of the dACC and striatum for positive self-descriptors, coupled with enhanced activity for negative self-descriptors, may heighten the risk for persistent depression.
