Which component in Brown's model suggests that processes occur simultaneously?

In Brown's model, the concept of parallel processing reflects how certain cognitive processes can occur simultaneously rather than sequentially. This means that multiple tasks or aspects of information can be handled at the same time, allowing for more efficient cognitive functioning. For example, while processing speech, the brain can simultaneously analyze phonetic details, syntactic structures, and semantic meanings. This is in contrast to sequential processing, where tasks are completed one after another, and distributed or isolated processing, which may imply different ways of handling information but do not emphasize the simultaneous nature of cognitive activities. The framework of parallel processing is essential for understanding how complex tasks, like language production and comprehension, can be managed seamlessly within the brain.
