writes about an Australian researcher named Renata Pronk, who has discovered that octopuses prefer HDTV
. She recruited 32 gloomy octopuses from the waters of Chowder Bay. Previously, researchers have reported little success when showing video to octopuses. Miss Pronk's insight was that the octopus eye is so refined that it might see standard PAL video, at 25 fps, as a series of stills. She tried HDTV (50 fps) and her subjects reacted to the videos of a crab, another octopus, or a swinging bottle on the end of a string. A further discovery is that octopuses show no trait of individual personalities, even though they exhibit a high level of intelligence. It would certainly be possible to quibble about the definition of "personality" employed, and whether Miss Pronk had successfully measured it.
