Here's looking at you, kid: attention to infant emotional faces in mothers and non-mothers.
Bottom Line: Infant facial cues play a critical role in eliciting care and nurturance from an adult caregiver.Finally, it was found that greater levels of mothers' self-reported parental distress was associated with less task interference when processing infant faces.We suggest that alterations in attentional processing in motherhood may constitute an adaptive behavioural change associated with becoming a parent.

Mentions: The dimensions of the stimuli were 2.1 cm (vertically) by 1.7 cm (horizontally). The faces were presented on a black background in a virtual triangle with the centre of each image placed at 1.3 cm from a central fixation cross (see Figure1). There was a 0.5 cm gap between images. Stimuli were viewed at a distance of 60 cm meaning that they were subtended at a visual angle of 4.5° vertically and 3.6° horizontally. The mean diameter of the iris was 2.60 mm for infant faces and 2.79 mm for adult faces, and 2.54 mm for happy faces, 2.29 mm for sad faces and 3.05 mm for neutral faces (with 1 pixel = 0.44 mm).
