- Summary:
-
An experiment was carried out on perceived difficulty of a simple attention task. Seven complex stimulus matrices were used, consisting of different numbers of pairs of consonants. The subjects' task was to search for targets determined by the experimenter one by one. Search time was measured as performance criterion. Perceived difficulty of the task was measured by the method of magnitude estimation, one of the matrices serving as standard. The results showed perceived difficulty to be a negatively accelerated function of both stimulus and response variables involved. It appears probable that the estimates of difficulty were contaminated by the structure and size of the visual field, particularly by the estimation of numerousness. It is concluded that isolation of the perception and, hence, of the estimation of difficulty is an important methodological problem in the area under study. (Author)
