The propositional approach to associative learning as an alternative for association formation models

Dickinson (2009) agrees with two of the core claims that were made in my target article (De Houwer, 2009): Associative learning effects (often) depend on (1) the formation of propositions and (2) the operation of nonautomatic processes. Whereas I derived these claims from propositional models of learning, Dickinson (2009) argues that they are also compatible with association formation models (AFMs). He also defends the position that only AFMs can explain “nonrational responses to associative experiences.” In this comment, I question whether there is much value in continuing to cling to AFMs.     

山西省与全国男学生BMI拟合的比较研究

依据2000年全国学生体质调研数据,应用科学研究方法,对山西省与全国城市6~22岁汉族男学生的BMI(身体质量指数)进行横向和纵向的系统比较分析,揭示了其内在的变化规律:从山西和全国的资料来看,由于学生处于生长发育期,身高和体重逐渐发育成熟,BMI增长值逐渐减低。山西、全国城市汉族男学生BMI增长值在年龄段上的分布趋势一致,快速增长期主要集中在9~13岁年龄段。在14岁之后增长值不断下降。山西城市汉族男学生BMI增长值普遍高于全国城市汉族男学生BMI增长值,6~8岁山西BMI低于全国,之后逐渐高于全国。
