Resource allocation theory, Polich (2007) suggests cortical measures may attenuate when processing demands increase. Thirteen HIV-negative women (M = 36.5) and 15 HIV-positive women (M = 36.1) infected were instructed to view neutral and negative IAPS images and then to detect rare tones in a subsequent auditory oddball task. A 2 x 2 ANOVA for the auditory P3 did not indicate a main effect for picture valence however an interaction was found between picture valence and serostatus at location...
Show moreResource allocation theory, Polich (2007) suggests cortical measures may attenuate when processing demands increase. Thirteen HIV-negative women (M = 36.5) and 15 HIV-positive women (M = 36.1) infected were instructed to view neutral and negative IAPS images and then to detect rare tones in a subsequent auditory oddball task. A 2 x 2 ANOVA for the auditory P3 did not indicate a main effect for picture valence however an interaction was found between picture valence and serostatus at location Fz, F(1,24) = 18.99, p<.001. During the visual ERP sequence an interaction between valence and serostatus was found at the Pz location, F(1,24) = 18.99, p<.001, meaning the late positive potential (LPP) was not modulated between viewing neutral and negative images in HIV-positive women. These findings suggest that the manifestation of HIV in women may alter the neural processing of emotions, though not to the detriment of a subsequent cognitive task.

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)...

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.
