Because siblings often fulfill a caregiver role in the home, this study investigated whether having siblings, and younger siblings in particular, impacts the reward value of and perceptual sensitivity to the baby schema. Participants completed a cuteness sensitivity rating task and an effort-based keypress task to measure the reward value of cuteness. They also reported whether they had siblings, and if so older vs younger siblings. Contrary to our hypotheses, having siblings did not influence the reward value of or perceptual sensitivity to baby schema.
