Bousfield和Sedgewick表明，作为时间的函数，产生到一个类别的联想的累积数量可以用一个具有参数sm（联想率）和C（产生联想的总数）的指数函数来描述。本研究采用两个实验，分别对16名和14名男女大学生进行了研究。实验中，被试在油印纸上以四分钟为一个时间段，对不同类别的样例进行了描述，并对不同类别的样例的mandC值之间的负相关性进行了验证。发现了预测的跨类别负相关（实验I，r=.54，p < .05，单尾检验;实验2，r=.75，p < .01）。具有低m值的类别具有高C值，反之亦然。这一效应可以用一个模型来解释，该模型假设样例在语义记忆中的存储密度或多或少。
Bousfield and Sedgewick showed that the cumulative number of associations produced to a category as a function of time could be described by an exponential function having the parametersm(rate of association) andC(total number of associates produced). In two experiments using male and female college students (N= 16 andN= 14, respectively), the present study investigated the hypothesis suggested by previous research, that the values ofmandCfor different categories are negatively correlated.Ss produced examples of different categories in four-minute periods per category on mimeographed sheets. The predicted negative correlation across categories was found (Experiment I,r= .54,p< .05, one-tailed test; Experiment 2,r= .75,p< .01). Categories with a lowmvalue had a highCvalue andvice versa.The effect can be explained by a model which assumes exemplars are stored more or less densely in semantic memory.
