Studies on Drive and Incentive in Perception IV: Some Effects of Sound and Background Brightness on the Perceived Size of Coins and Discs.
Abstract
The research was designed to test iplicaions of the hypothesis that the Bruner-Goodman phenomenon i an instance of sensory interaction. Rich and poor children estimated the size of coins and dscs under sound vs. no sound and two levels of background brightnes. Contrary to predicion, no reltion was found to exit between sound level and size estimation, alhough sch a relaton did exist for bckground brightness. The findings failed to replicate the dat of Bruner and Goodman, whereas they were in substantial agreement with those of CARTER AND hooler. These results were as follows: (1) Large coins tended to be judged lager, and small coins judged smaller than neutral discs of comparable size; and (2) No differential affect was observed on the estmations of coins and discs as a function of economic status. There was, however, a reliale tendency for the children of lower economic stats to overestimate both coins and discs when compared with those of higher status. (Author)
