WANT to experience the benefits of super-sharp high-definition TV without buying a new set? Simply tell yourself that you are watching HD and put up a few posters. That鈥檚 the implication of a Dutch study into how expectations affect viewers鈥� perceptions ().
Two groups of 30 people watched the same video clip, individually, on the same television. Half were told to expect a better experience thanks to HD technology, an impression backed up by posters, flyers and an extra-thick cable connected to the screen. The other half were told to expect a normal DVD signal.
In questionnaires afterwards, the group told to expect HD reported that they had witnessed significantly sharper, more detailed images.
