Psycholinguistics in the study of how people process language. People use spoken language to coordinate such joint activities as business transactions, story telling, and planning. In doing so, they work turn by turn, relying on adjacency pairs, such as question plus answer, or assertion plus acknowledgment, and they ground what is said as they proceed. Speaking itself is a process with overlapping stages. For each utterance, speakers decide on a message, select the concepts and syntactic frame required for that message, assemble these in an appropriate order, formulate a phonological code, and then articulate the right sounds. Listeners, for their part, take in these sounds segment by segment. They narrow down on words and phrases instantly as these become specified uniquely in the context. Listeners rely on pragmatic information not only in this process, but also in filling conceptual gaps in their understanding with bridging and elaborative inferences. The words people use are stored in a mental lexicon as entries with conventional meanings. But in talking face‐to‐face, people also use gestures—such as emblems, iconic gestures, and pointing—which they coordinate with their words. People also create broader models of the situations being spoken about. These models represent such things as visual and spatial features of the situations, cultural schemas, and mental simulations of imagined scenes and events.
