<P> Zenon Pylyshyn suggested a propositional model of cognition where people do not conceptualize ideas in images but rather in meaningful relationships . In this theory , epiphenomena refer to images because they are merely products people conceptualize from their actual thought processes . Pylyshyn defends his claim by explaining that we only see images when we envision the form of an object . While visualizing objects or actions is a frequent process in our mind , it does not occur when we are considering the meaning behind an action or the non-visual properties of an object . There are many concepts we simply can not envision . Additionally , when envisioning an image , it changes based on our preconceived notions , suggesting that semantic relations precede visual images . Unfortunately , the idea of epiphenomena in propositional theory is largely subjective and not falsifiable . </P>
