Brain and personality bases of insensitivity to infant cues in neglectful mothers: An event-related potential study / María José RODRIGO in Development and Psychopathology, 23-1 (January 2011)
[article]
Titre : Brain and personality bases of insensitivity to infant cues in neglectful mothers: An event-related potential study Type de document : Texte imprimé et/ou numérique Auteurs : María José RODRIGO, Auteur ; Inmaculada LEON, Auteur ; Ileana QUINONES, Auteur ; Agustín LAGE, Auteur ; Sonia BYRNE, Auteur ; María Antonieta BOBES, Auteur Année de publication : 2011 Article en page(s) : p.163-176 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This investigation examined the neural and personality correlates of processing infant facial expressions in mothers with substantiated neglect of a child under 5 years old. Event-related potentials (ERPs) were recorded from 14 neglectful and 14 control mothers as they viewed and categorized pictures of infant cries, laughs, and neutral faces. Maternal self-reports of anhedonia and empathy were also completed. Early (negative occipitotemporal component peaking at around 170 ms on the scalp [N170] and positive electrical potential peaking at about 200 ms [P200]) and late positive potential (LPP) components were selected. Both groups of mothers showed behavioral discrimination between the different facial expressions via reaction time and accuracy measures. Neglectful mothers did not exhibit increased N170 amplitude at temporal leads in response to viewing crying versus laughing and neutral expressions compared to control mothers. Both groups had greater P200 and LPP amplitudes at centroparietal leads in response to viewing crying versus neutral facial expressions. However, neglectful mothers displayed an overall attenuated brain response in LPP that was related to their higher scores in social anhedonia but not to their empathy scores. The ERP data suggest that the brain's failures in the early differentiation of cry stimuli and in the sustained processing of infant expressions related to social anhedonia may underlie the insensitive responding in neglectful mothers. The implications of these results for the design and evaluation of preventive interventions are discussed.
