There are two influences contributing to perceptual organization: innate brain structure and personal past experiences.
Both boxes of Mysak'‰s model have the ability to add strings of their own in the brain‰s creation of our reality.
Our understanding of these two sides of perception come from studies by the Gestaltists and the Behaviorists of past years.
The Gelstalt psychologists, who stemmed mainly from Europe, took a natavistic or structural (Species Specific) view of perception. They used, by and large, a subjective approach in their research.
They might, for example, stick a subject with an pin, and then ask him how he felt--what did he experience.
They noted, among other things (but not from that fictitious experiment above), that more was achieved in perception that could be accounted for by the stimulus alone--an example of the ‹added stringŠ I was talking about earlier. I have attempted to give a feeble demonstration of this phenomenon in the notes below.
NOTES: A rather feeble demonstration of perceptual modification.
