Intimate Partner Violence (IPV) is often associated with Post-traumatic Stress Disorder (PTSD) and is characterized by disturbances in attention and hyperarousal. The aim of this study was to investigate the arousal related to recognition of emotional face in IPV women. This study examined the event-related potential (ERP) N170 component to target detection, during the presentation of Nim Stim Face Stimulus Set, with Emo No Go paradigm. The task consisted of pressing a button when the subject saw a neuter face expression. Participants were 10 women with IPV, recruited in a Center Against Family Violence, compared to aged matched controls. To assess both groups we administered the Beck Depression Inventory II, Beck Anxiety Inventory and a PTSD. GLM analysis was computed for N200 amplitude and latency and showed a significant effect by group (Group p=,018; Target p=,406). Post hoc analysis in amplitude showed significant value in direction of a higher amplitude in IPV group; post hoc analysis in latency showed significant value in direction of faster latency in IPV group. Lateralization analysis showed higher amplitude in right hemisphere in IPV group (Right p=,041). The behavioral result confirms a significant difference (Group =,00; Target=,00; Target*Group=,00) in direction of a faster RT in IPV group. IPV group exhibits a lower sensitivity threshold on emotional face recognition in behavioral and ERP results, and it could be a sensibilization in elicitation of emotional arousal, but this activation is independent from modality of expression.

Abstract
Intimate Partner Violence (IPV) is often associated with Post-traumatic Stress Disorder (PTSD) and is characterized by disturbances in attention and hyperarousal. The aim of this study was to investigate the arousal related to recognition of emotional face in IPV women. This study examined the event-related potential (ERP) N170 component to target detection, during the presentation of Nim Stim Face Stimulus Set, with Emo No Go paradigm. The task consisted of pressing a button when the subject saw a neuter face expression. Participants were 10 women with IPV, recruited in a Center Against Family Violence, compared to aged matched controls. To assess both groups we administered the Beck Depression Inventory II, Beck Anxiety Inventory and a PTSD. GLM analysis was computed for N200 amplitude and latency and showed a significant effect by group (Group p=,018; Target p=,406). Post hoc analysis in amplitude showed significant value in direction of a higher amplitude in IPV group; post hoc analysis in latency showed significant value in direction of faster latency in IPV group. Lateralization analysis showed higher amplitude in right hemisphere in IPV group (Right p=,041). The behavioral result confirms a significant difference (Group =,00; Target=,00; Target*Group=,00) in direction of a faster RT in IPV group. IPV group exhibits a lower sensitivity threshold on emotional face recognition in behavioral and ERP results, and it could be a sensibilization in elicitation of emotional arousal, but this activation is independent from modality of expression.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
