Comparative Perspectives on Pointing and Joint Attention in Children and Apes

摘要: Author(s): Krause, Mark A | Abstract: Thecomprehension and production of manual pointing joint visual attention are already well developed when human infants reach their second year. These early developmental milestones mark the infant's transition into accelerated linguistic competence shared experiences with others. The ability to draw another's toward distal objects or events facilitates development complex cognitive processes such as language acquisition. comparative approach allows us examine evolution these phenomena. Of recent interest is whether non-human primates also gesture manipulate eye gaze direction others communicating. However,all captive apes do not use referential gestures pointing, appear understand meaning attention. Those that show evidence abilities differ in expression them, this may be osely related rearing history. This paper reviews literature on topic goal identifying why develop other species, potential sources existing individual variation expression.
