Discrimination of native versus non-native between- and withinarticulatory organ fricative contrasts was examined in 6 and 12 month-old infants. 12 month-olds discriminated between- (tongue-tip vs. lips) but not within-organ place contrasts (two tongue tip constriction locations), but 6 month-olds only did so for the non-native between-organ contrast. The results support the Articulatory Organ Hypothesis that infants attend more to differences between active articulatory organs than to differences between specific gestures of a single organ (e.g., constriction location or degree).
