AbstractMelinder, A., Konijnenberg, C., Hermansen, T., Daum, M., & Gredebäck, G. (2015) The developmental trajectory of pointing perception in the first year of life. Experimental Brain Research, 233, 641-647.
The present study investigated the development of the neural basis of pointing perception in 6- and 12-month-old infants. In a spatial-cueing paradigm, infants were presented with a peripheral target followed by a hand pointing towards (congruent condition) or away (incongruent condition) from the previously cued location. EEG responses to the presentation of the hand were measured. Twelve-month-olds demonstrated larger amplitudes of ERP component P400 to incongruent compared to congruent pointing gestures over posterior temporal areas, 6-month-olds did not show any differential activation. This result suggests that the neural correlates of pointing perception undergo substantial development between 6 and 12 months of age.
