Detecting self-generated actions and imitating other-generated actions are important abilities in order to interact with others. The relationship between these domains was investigated in 6-8-month-old infants. In a contingency-preference task, infants observed their own legs on a real-time and a delayed video display. In an imitation task, the…

The current study examined whether and how the presence of a positive or a negative emotional expression may affect the face recognition process at 3 months of age. Using a familiarization procedure, Experiment 1 demonstrated that positive (i.e., happiness), but not negative (i.e., fear and anger) facial expressions facilitate infants' ability to…

Infants' visual preference for infant-directed (ID) faces over adult-directed (AD) faces was examined in two experiments that introduced controls for emotion. Infants' eye movements were recorded as they viewed a series of side-by-side dynamic faces. When emotion was held constant, 6-month-old infants showed no preference for ID faces over AD…

A head-mounted camera was used to measure head direction. The camera was mounted to the forehead of 20 6- and 20 12-month-old infants while they watched an object held at 11 horizontal (-80° to + 80°) and 9 vertical (-48° to + 50°) positions. The results showed that the head always moved less than required to be on target. Below 30° in the…

When face processing studies find sex differences, male infants appear better at face recognition than female infants, whereas female adults appear better at face recognition than male adults. Both female infants and adults, however, discriminate emotional expressions better than males. To investigate if sex and age differences in facial scanning…
