Unformatted text preview: rence than for explicit stories -  actually, bilateral only for good comprehenders Good (high Working Memory) comprehenders show more RH activation than do not-so-good (low Working Memory) comprehenders Inferior frontal gyrus Posterior superior temporal gyrus Virtue et al. 2008 Inferences in the brain:  Converging evidence Ideally, always look for replication and converging evidence Each method (imaging and other) has pros and cons R So what? What does fMRI add? Bilateral activation, integration and selection in natural language processing Knowing where processing occurs informs and constrains what and how it occurs Semantic integration as a separate process Three component semantic processes, across 2 hemis, involved in drawing inferences Conclusions about inferences •  Semantic integration builds up as story hints that some event might occur: anterior STG; RH •  At coherence break: integration and activation (STG), especially in LH or bilateral (high WM) •  completing the inference requires selection (IFG) Important clarifications •  Not “inference areas” –  Each process participates in many functions –  Recruitment of process varies with demand •  Tight comparison not reveal whole network –  Just areas that differ when stories imply versus explicitly state events •  RH and LH cooperate - –  you understand w/ both, simultaneously Asymmetric dy...
