Two experiments investigated the processing of the spatial and causal dimensions of situation models. In Experiment 1, participants read texts varying in spatial and causal demands while responding to on-line spatial and causal probes. Experiment 2 used the same design, but used texts that more tightly integrated spatial and causal information. In both experiments, spatially oriented dependent measures were generally influenced by spatial, but not causal, demands, whereas causally oriented measures were influenced by causal, but not spatial, demands. In addition, spatially oriented dependent measures were generally correlated with a measure of spatial working memory capacity, whereas causally oriented measures were correlated with a measure of verbal working memory capacity. These results indicate that spatial and causal dimensions of situation models are maintained and elaborated independently in different working memory subsystems.
两项实验研究了情境模型的空间维度和因果维度的加工过程。在实验1中，参与者在对在线空间和因果探测进行反应的同时阅读了在空间和因果要求上有所不同的文本。实验2采用了相同的设计，但使用了更紧密整合空间和因果信息的文本。在这两项实验中，以空间为导向的因变量测量通常受空间要求而非因果要求的影响，而以因果为导向的测量则受因果要求而非空间要求的影响。此外，以空间为导向的因变量测量通常与空间工作记忆容量的测量相关，而以因果为导向的测量则与言语工作记忆容量的测量相关。这些结果表明，情境模型的空间维度和因果维度在不同的工作记忆子系统中是独立维持和细化的。
