From the perspective of psycholinguistic analysis,language use in terms of  perception,comprehension production follows a certain patternwhich involves the coordination  of various language centers.  
 When we speak,words are drawn from Wernicke’s area transferred to Broca’s area, which  determines the details of their form pronunciation.The appropriate instructions are then sent to  he motor area which controls the vocal tract to physically articulate the words.  When we hear something 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.
