Perceptual defense and vigilance to perinatal stimuli.
The presentation times (milliseconds on a computer screen followed by a masking grid) required for the correct identification of tachistoscopically presented perinatal stimuli were compared for 30 pregnant women and 25 perimenopausal women. Analysis indicated a differential facilitation or inhibition of perception in logical relation to subjects' closeness to pregnancy or menopause: pregnant women are quicker to identify stimuli related to pregnancy or babies but slower to recognize pictures of a pregnant woman with her father or mother. This supports the validity of measurements based on the theory of perceptual defense or vigilance.
