			We didn't find significant higher activation for communicative versus emotional faces in the ROI that I defined and the pre-defined ROIs. This result didn't replicate Bernstein's result, which has several possible reason. First, we used different stimuli than theirs. In our stimuli, communicative faces are actually trying to convey some information, whereas in their experiment, speech faces were pronouncing nonsense syllables. Second, maybe they have more stats power by showing subjects more stimuli than we did.<br>

	It's an important issue for researcher to investigate how visual speech information is processed in the brain. A traditional view states that the visual speech information is integrated in the unisensory cortices which is the visual areas. In Bernstein (2010) they found a more anterior activation in STS for speech than nonspeech stimuli. Here we are going to use dynamic stimuli to test whether their finding can be replicated.<br>		It's an important issue for researcher to investigate how visual speech information is processed in the brain.

			In their research, the speech stimuli are videos of people reading nonsense syllables, and the nonspeech gestures were puff, kiss, raspberry, growl, yawn, smirk, fishface, chew, furn, nose wiggle, and frown-to-smile.<br>
