64 views6 pages

Document Summary

Face perception: infants like looking at faces, seek out visual info. One month old look more at periphery of face, general. Although like to look at complex features they prefer face like features. Iv? age, and the human vs. monkey faces. Results 6 moth olds did very well in discriminating with human faces and discriminating monkey faces maybe because their synapses and neurons are specialised yet. 9 month olds and adults did well with human faces but not monkey faces maybe because their synapses and neurons are specialised due to experiences. Face processing becomes specialized over the course of development. These results suggest that the perceptual narrowing" phenomenon may represent a more general change in neural networks involved in early cognition. (p. 1321) Replicated by other research using slightly different method (habituation instead of preferential looking): Video clip (bbc neural synapses video; we saw this a few weeks ago): http://www. youtube. com/watch?v=8j-jflthhks.
