Three- to 4-month-olds preferred attractive over unattractive domestic and wild cat (tiger) faces (Experiments 1 and 3). The preference was not observed when the faces were inverted, suggesting that it did not…

Studies of orientation perception in infants and children have revealed an "oblique effect," that is, a performance advantage for tasks involving horizontal and vertical stimulus orientations compared with tasks involving oblique orientations. The two studies reported support the hypothesis that oblique stimulus orientations are treated…
