<< Continued from Sensory Processing

What's more, if you are given sugar with coffee and only sugar, it is easier to recognize when it is only sugar because the vividness of its taste is more. Such vividness provided by temporal spacing between events also aid in different senses to tie up to their sources more strongly.

Without temporal variation, sensory extraction poses problems even when working in the same sensory modality, as seen in the following example: Hold a hot object in one hand, and after while, hold a cold in another. Notice that when you are holding both objects, the hot object feels colder and the cold object feels warmer, as it is sensory summation. Such summation also makes it possible to extract taste and smell jointly to create flavour in the food we eat.

In the cases where a person starts using a sensory modality he had never access to before, e.g., when a person who is deaf from birth starts hearing, the strong knowledge accumulated from years of composition and temporal variation extraction of other senses helps him segregate it from them.

In a nutshell, to optimally work with VP's limitation of processing one task at a time, analyzed data of content of all senses is summated by LB, which sends data of the attended area to VP, which extracts each sensory modality using composition extraction and temporal variation extraction.

The reason for summation-extraction process is to convert data from parallel processing environment into serial processing environment, thereby providing benefits of parallel processing in a serial processing environment.

As we start learning and using sensory extraction from early stages in life on a moment by moment basis, once learnt, it becomes like a second nature to us.
