Infants' face-recognition by primiparous and multiparous women.

We have compared the ability of 49 primiparous and 75 multiparous women to recognize photographs of their newborn infants. In line with previous research on infant cries, we found that multiparous women who had been with their infant 0.5 to 5.0 hr. were significantly more successful in recognizing their infants' photographs than primiparous women with comparable exposure to their newborns. For women who had not been with their infants more than 5 hr., parity was not related to recognition. We propose that the transient performance deficit of the primiparous women indicates a short-lived impairment of perceptual/cognitive skills associated with their more stressful childbearing experience.
