For instance, if for some reason I'm already thinking about something that has no relation to any information coming in from any of my senses, just some random thought, will this cause any new information coming in from these senses to potentially not be processed?
This is kind of related to my understanding of HIP( human information processing ). I've recently seen a diagram of HIP where what is in working memory is either information from our senses that we are attending to and information from long term memory.
But where does random thoughts that we have through out the day come in? This has to be accounted for as well, I would think.
