Abstract
Although the need to investigate the cognitive processes by media research was recognized as early as 1961, there has been hardly any such attempt. The lack of experimental techniques by which the “black box” can be reached is probably responsible for the lack of research attention. This experiment employs a technique called blank trial to investigate cognitive strategies used by S in solving problems presented by slide. It is assumed that this technique may systematically investigate and presumably externalize cognitive processes.
