Effects of experience on size discrimination and attitudes toward the Susan B. Anthony coin.
Effects of experience with the Susan B. Anthony dollar on size discrimination and attitudes toward the coin were investigated. Those who used the coin for 4 wk. were quite accurate in discriminating its size visually while those without experience confused the size of the dollar coin with the size of the quarter. On a coin-selection task experienced subjects were no more accurate than inexperienced subjects but differed in type of error, confusing the dollar coin with the half-dollar coin more frequently. In contrast, the errors of inexperienced subjects were unsystematic. No attitudinal changes resulting from experience with the coin were found.
