The present study examined the neural correlates of speech and hand gesture comprehension in a naturalistic context. Fifteen participants watched audiovisual segments of speech and gesture while event-related potentials (ERPs) were recorded to the speech. Gesture influenced the ERPs to the speech. Specifically, there was a right-lateralized N400(More)
Why is it that people cannot keep their hands still when they talk? One reason may be that gesturing actually lightens cognitive load while a person is thinking of what to say. We asked adults and children to remember a list of letters or words while explaining how they solved a math problem. Both groups remembered significantly more items when they(More)
Gesture and speech are assumed to form an integrated system during language production. Based on this view, we propose the integrated-systems hypothesis, which explains two ways in which gesture and speech are integrated--through mutual and obligatory interactions--in language comprehension. Experiment 1 presented participants with action primes (e.g.,(More)
Most theories of pragmatics take as the basic unit of communication the verbal content of spoken or written utterances. However, many of these theories have overlooked the fact that important information about an utterance’s meaning can be conveyed nonverbally. In the present study, we investigate the pragmatic role that hand gestures play in language(More)
Recently, much research has explored the role that nonverbal pointing behaviours play in children's early acquisition of language, for example during word learning. However, few researchers have considered the possibility that these behaviours may continue to play a role in language comprehension as children develop more sophisticated language skills. The(More)
Previous research has demonstrated a link between language and action in the brain. The present study investigates the strength of this neural relationship by focusing on a potential interface between the two systems: cospeech iconic gesture. Participants performed a Stroop-like task in which they watched videos of a man and a woman speaking and gesturing(More)
The present study investigates whether knowledge about the intentional relationship between gesture and speech influences controlled processes when integrating the two modalities at comprehension. Thirty-five adults watched short videos of gesture and speech that conveyed semantically congruous and incongruous information. In half of the videos,(More)

People of all ages, cultures and backgrounds gesture when they speak. These hand movements are so natural and pervasive that researchers across many fields – from linguistics to psychology to neuroscience – have claimed that the two modalities form an integrated system of meaning during language production and comprehension. This special relationship has(More)
This article investigates the role that nonverbal actions play in language processing over 3 different time frames. First, we speculate that nonverbal actions played a role in how formal language systems emerged from our primate ancestors over evolutionary time. Next, we hypothesize that if nonverbal behaviors played a foundational role in the emergence of(More)
