Independent groups of observers made magnitude estimates of geographical area or interstate distance. In Experiment 1, observers estimated the areas of nations or of states of the United States from memory. In Experiment 2, estimates of state area were made either with a map present or from memory after the map had been studied. Similarly, in Experiment 3,(More)
Recent studies have investigated the effect of an irrelevant size change on reaction time in tasks involving comparison of same or different shapes. In most cases, however, studies have examined simultaneous presentation or else successive presentation where the second stimulus was always larger than the first. In the present study, subjects made(More)
Subjects compared pairs of animal, country, and car names, which had been ranked along concrete (perceptual) and abstract (nonperceptual) dimensions by an independent group (e.g., animals were rated for size and ferocity). For judgments based on abstract and concrete dimensions, comparison time decreased as the difference between the rated scale values of(More)
In a short-term recognition memory experiment with words, subjects: (1) subvocally rehearsed the words, (2) generated a separate visual image for each word, (3) generated an interactive scene with such images, or (4) composed a covert sentence using the words in the memory set. Contrary to Seamon's (1972) results in a similar study, a serial memory search(More)
