From the perspective of psycholinguistic analysis,language use in terms of perception,comprehension and production follows a certain pattern which involves the coordination of various language centers. When we speak,words are drawn from Wernicke’s area and transferred to Broca’s area, which determines the details of their form and pronunciation. The appropriate instructions are then sent to the motor area which controls the vocal tract to physically articulate the words. When we hear something and try to comprehend it,t he stimulus from the auditory cortex is transmitted to Wernicke‘s area,where it is then interpreted. When we perceive a visual image,a message is sent to the angular gyrus,where it is converted into a visual pattern.
