本研究的目的是检查工作记忆在心算中的作用。成人（n = 96）单独解决多位数算术问题（例如，52 + 3；3 + 52），并结合语音记忆负荷（即非单词，如 gup）或视觉记忆负荷（即星号的随机模式）。参与者解决以垂直格式提出的问题的速度明显快于以水平格式提出的问题。他们解决两位数优先问题（例如 52 + 3）的速度也比相反问题（例如 3 + 52）更快，但前提是问题是水平呈现的。对于水平呈现问题的参与者来说，语音负载条件下的表现比视觉负载条件下的表现更差，而当问题垂直呈现时，视觉负载条件下的表现比语音负载条件下的表现更差。目前的研究提供的证据表明，工作记忆的语音和视觉方面都参与心算，但每个工作记忆成分的作用将取决于呈现格式等因素。
The goal of the present research was to examine the role of working memory in mental arithmetic. Adults (n = 96) solved multidigit arithmetic problems (e.g., 52 + 3; 3 + 52) alone and in combination with either a phonological memory load (i.e., nonwords, such asgup) or a visual memory load (i.e., random pattern of asterisks). The participants solved problems presented in a vertical format significantly faster than problems presented in a horizontal format. They also solved double digit first problems (e.g., 52 + 3) more quickly than the reverse (e.g., 3 + 52), but only when the problems were presented horizontally. Performance was worse in the phonological load condition than in the visual load condition for the participants who solved problems presented horizontally, whereas performance was worse in the visual load condition than in the phonological load condition when problems were presented vertically. The present research provides evidence that both phonological and visual aspects of working memory are involved in mental arithmetic but that the role of each working memory component will depend on such factors as presentation format.
