Event-related potentials (ERPs) and behavioral ratings were collected from 30 female subjects who were exposed to picture slides. The slides belonged to five affective categories whose content was babies, dermatological cases, ordinary people, male models, and female models. Based on the day of testing relative to their menstrual cycle, the subjects were grouped according to their expected levels of androgens, estrogen, or progesterone. The data were examined to determine whether any ERP component or behavioral rating (non-erotic/erotic, unpleasant/pleasant, simple/complex, and low arousal/high arousal) varied as a function of subjects' hormone defined menstrual phase. Only the P3 component was sensitive to menstrual phase. The P3 to babies and male models was largest when progesterone levels were high. High progesterone was also associated with a decrease in the complexity and eroticism of all slide categories. An increase in the pleasantness of all categories was evident when estrogen levels were high. The results are interpreted as support for an "adaptive context updating" theory of the P3 component of ERPs.

PIP: Event-related potential (ERP), a type of EEG wave measured after visual stimulus, is hypothesized to be associated with "context updating." ERP waves were recorded in 30 women who viewed 20 slides of babies, men, women, people, or dermatological cases, previously determined to evoke neutral, erotic, pleasant or unpleasant responses, and correlated with phases of the menstrual cycle. Menstrual phases were categorized as estrogenic, progestogenic, or androgenic by Cycle Day, according to self report of the date of onset of the following menses. Each woman was fitted with 3 scalp electrodes at Fz, Cz, and Pz, and apparatus for recording and adjusting for artifacts due to eye movements. Each subject viewed 20 slides 8 times each, and rated them as erotic/nonerotic, pleasant/unpleasant, simple/complex, low arousal/high arousal. Results were analyzed by principal component analysis and multivariate analysis of variance. The P3 component of the ERP wave varied significantly with menstrual phase: on Cycle Days 16-24 when progesterone levels were presumed high, the P3 wave response to babies and male models was largest, and subjects rated slides as less erotic and complex. On Cycle Days 9-13 and 22-25 when estrogen levels were presumed high, subjects rated all slide categories as more pleasant. The results were interpreted as supporting the adaptive context updating theory of the P3 component of ERPs.
