Neuropsychological correlates of emotion regulation in HIV

Diminished affective behavior is a frequently observed concomitant of cognitive dysfunction in the Human Immunodeficiency Virus (HIV), yet little is known about their relationship. A neuropsychological battery and electroencephalogram (EEG) recording was conducted on 29 HIV+ (Mage = 35.6 years, SD =5.36) and 30 HIV- (Mage =32.9 years, SD =6.39) women recruited from a family AIDS care program in South Florida. Using an emotion regulation paradigm, we compared event-related potentials (ERPs) following cues to view-neutral, view-negative and reappraise-negative images from the International Affective Picture System (IAPS). A group X instruction interaction was found for the P200 and early (400-1000 ms) late positive potential (LPP). Executive function, i.e., frequent task-switching predicted the attenuation of the early and late LPP following cues to up-regulate negative emotions. Greater response inhibition predicted attenuation of the LPP during the down-regulation of negative emotions. These findings suggest limited cognitive resources for the reappraisal of emotions in women with HIV. / by Roger Christopher McIntosh. / Thesis (Ph.D.)--Florida Atlantic University, 2012. / Includes bibliography. / Mode of access: World Wide Web. / System requirements: Adobe Reader.
