RESUMEN
This study aims to analyze culture-specific development of maternal interactional behavior longitudinally. Rural Cameroonian Nso mothers (n = 72) and German middle-class mothers (n = 106) were observed in free-play interactions with their 3- and 6-month-old infants. Results reveal the expected shift from a social to a nonsocial focus only in the German middle-class mothers' play interactions but not the rural Nso mothers' play. Nso mothers continue their proximal interactional style with a focus on body contact and body stimulation, whereas German middle-class mothers prefer a distal style of interaction with increasing object-centeredness. These cultural differences are in line with broader cultural models and become more accentuated as the infants grow older.

Four experiments were conducted with 5- to 11-year-olds and adults to investigate whether facial identity, facial speech, emotional expression, and gaze direction are processed independently of or in interaction with one another. In a computer-based, speeded sorting task, participants sorted faces according to facial identity while disregarding facial speech, emotional expression, and gaze direction or, alternatively, according to facial speech, emotional expression, and gaze direction while disregarding facial identity. Reaction times showed that children and adults were able to direct their attention selectively to facial identity despite variations of other kinds of face information, but when sorting according to facial speech and emotional expression, they were unable to ignore facial identity. In contrast, gaze direction could be processed independently of facial identity in all age groups. Apart from shorter reaction times and fewer classification errors, no substantial change in processing facial information was found to be correlated with age. We conclude that adult-like face processing routes are employed from 5 years of age onward.
