Children's Use of Morphological Cues in Real-Time Event Representation.

The present study investigated whether and how fast young children can use information encoded in morphological markers during real-time event representation. Using the visual world paradigm, we tested 35 adults, 34 5-year-olds and 33 3-year-olds. The results showed that the adults, the 5-year-olds and the 3-year-olds all exhibited eye gaze patterns that reflected a rapid use of morphological cues during real-time event representation. There was no difference in the time course of the eye gaze patterns of the 5-year-olds and those of the adults, indicating that 5-year-old children already have adult-like processing abilities and they can use morphological cues as effectively as adults during real-time event representation. However, a 400 ms delay was observed in the eye gaze patterns by the 3-year-olds as compared to the 5-year-olds and the adults. We proposed that the observed difference might reflect a difference in the general cognitive processing abilities between the three age groups. Due to the immature cognitive processing abilities of 3-year-olds, it took longer for them to progress their eye movements to the target pictures as compared to older children and adults.
