Human survival depends on care received early in life. Infants need to capture adults' attention to have their basic needs met. Therefore, infant stimuli are prioritized by the attention system in adults, resulting in an attentional bias toward infant faces. We conducted a systematic review of the literature on behavioral measures of attentional bias toward infant faces. PubMed, PsycINFO, and ISI Web of Knowledge databases were used. The review suggests the existence of a measurable attentional bias toward infant faces and a positive correlation between attentional bias toward infant distress and the quality of mother-infant relationship. Depressive symptoms and breastfeeding modulate this behavior in women. Parental status and sex also influence the attentional prioritization of infant faces. Evidence indicates that differences in attentional bias are associated with clinical symptoms and variations in maternal behavior, reinforcing the potential use of attentional bias as a behavioral marker of clinical outcomes.
