Totally with you here. Not a neuroscientist. But I am a computer scientist. Lots of strong opinions, not a lot of strong facts. The analogies are interesting but they break down quick.
"We don't create representations of visual stimuli"..."We don't retrieve information or images or word from memory registers" Neither do computers in many cases. It's as if the author is saying because in the brain isn't a tape recorder or film camera then it doesn't work like a computer. Nope. Studies show that much like a computer we encode information as we store it. Because we encode it fancy ( or weird :-) doesn't mean its not encoded or retrieved. The Dollar Bill example is a red herring.
Just ppitballing here: What if, instead of creating an image for the dollar, the subject's mind created a visual'thumbnail' and 'hash' of the real dollar. The thumbnail she can recall easily and lets her draw 'enough' of the bill to be vaguely recognizable. The hash, lets her recognize the real deal whenever she sees it. She simply compares the hash of this new object with list of hashes, and if its a dollar the mind finds a match. Of course, it far more sophisticated, but these simple methods, cleanly account for what the author observed.
