23 month visit (Happiness, Balloons, Reward/Punish, C3PO_23)

Longitudinal Study - Age Range: 23.0 - 25.0 - Happiness: looking at infants sharing behaviours with puppets - Balloons: infants will watch one researcher create a drawing or clay sculpture while another researcher destroys it. We will then give infants balloons to share with the researcher who have destroyed the object. - Reward/Punish: Infants will watch a puppet show in which a puppet is helped or hindered by two other puppets. We will then give infants a chance to give or take a treat away from the helpful or unhelpful puppets. - C3PO_23: We will show infants a series of faces and abstract patterns on a screen. We will then monitor the extent to which they look at one face or pattern over another presented to them.
