Fig 5.
Looking time at happy or angry faces.
Infants’ mean looking time (s) in function of voices (angry or happy) and emotional faces (angry: blue or happy: green). After hearing a happy voice, infants look longer at the angry face than the happy face (F(1, 23) = 4.85, p < .05). The vertical bars represent positive standard errors (s.e.m.),*p < .05.
Fig 6.
Looking times at happy or angry AOIs (mouth or eyes).
Infants’ mean looking time (s) in function of the emotional voices (happy or angry) and emotional AOIs (happy: green or angry: blue). The angry mouth is looked at longer than the happy mouth F(1, 23) = 12.39, p < .01. After the happy voice, the angry mouth is looked at longer than the happy mouth (F(1, 23) = 8.32, p < .01). The vertical bars represent positive standard errors (s.e.m.), **p < .01.
