title: Effects of experience on size discrimination and attitudes toward the Susan B. Anthony coin.
abstract: 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.
