双重编码理论认为，混凝土的处理优于抽象（言语）刺激是由2个系统的操作（即想象中的和言语）用于混凝土刺激的，而不仅仅是1（抽象刺激）。这些言语和想象的系统分别与大脑的左和右半球有关。上下文可用性理论认为，混凝性效应是由单个系统中的处理差异引起的。这些理论的优点是通过在2个实验中检查事件相关大脑电位的地形分布（词汇决策和具体提取分类）来研究的。结果与双重编码理论最一致。特别是，通过具体和抽象的单词引起了N400样负性的不同头皮分布。
Dual-coding theory argues that processing advantages for concrete over abstract (verbal) stimuli result from the operation of 2 systems (i.e., imaginal and verbal) for concrete stimuli, rather than just 1 (for abstract stimuli). These verbal and imaginal systems have been linked with the left and right hemispheres of the brain, respectively. Context-availability theory argues that concreteness effects result from processing differences in a single system. The merits of these theories were investigated by examining the topographic distribution of event-related brain potentials in 2 experiments (lexical decision and concrete-abstract classification). The results were most consistent with dual-coding theory. In particular, different scalp distributions of an N400-like negativity were elicited by concrete and abstract words.
