In the JP universe, a paleontologist actually did a study on the rex's braincase, and reasoned that the brain would have been similiar in design to that of a frog's; particularly the sensory regions. The only problem is, he fucked it up. Even at the time of
TLW it was an obsolete theory, but Baselton was a little out of the loop, since he stood there like a moron when he should have been running his ass off.
Malcom gave the reason of it not being hungry, having just eaten a goat and a lawyer. How likely is that?
How likely is what? The dinosaurs on Isla Nublar were dinosaur/frog hybrids, and any bugs in their visual accuity is the result of that. Apparently, they fixed said bug in the Site B stock. Luck of the draw that Grant and the kids made it by believing a bad theory (which happened to be right for the wrong reasons) while Henry Baselton's remains are so much crusty rex shit.
And would a rex attack something if they weren't hungry? Who knows, there's no way to know for sure. The best we could do is turn to modern anologues, the only problem is the only two animal types that come close to being analogues are crocodiles and birds. And their brains really aren't all that similar.
Generally, crocs don't kill for fun. But they'll kill to get anything out of their territory or away for their nest. Birds run the gammut from being sadistic fuckers to completely beneign when not hungry, but birds are more intelligent than crocs, and have the energy to spare.
Going off of allosaur braincase casts, a large theropod's brain is much more crocodile than bird, with much more of the space dedicated to sensory software than processing power. But they're extinct, so the best we can do is convincing speculation.
