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.
研究了使用苏珊·B·安东尼一元硬币的经历对大小辨别以及对该硬币态度的影响。使用该硬币四周的人在视觉上辨别其大小相当准确，而没有相关经验的人则会将一元硬币的大小与二十五美分硬币的大小混淆。在一个硬币选择任务中，有经验的受试者并不比没有经验的受试者更准确，但在错误类型上有所不同，他们更频繁地将一元硬币与五十美分硬币混淆。相比之下，没有经验的受试者的错误是不系统的。未发现因使用该硬币的经历而导致的态度变化。
