“Inferencing
Processes After Right Hemisphere Brain Damage: Maintenance of Inferences” by
Lehman-Blake assesses deficits in adults who have RHD; specifically, in the ability make predictive inferences using contextual cues in maintenance. It is a replication and extension of a prior study, “Predictive inferencing in adults with right hemisphere brain damage” conducted by Lehman-Blake and C. Thompkins, in 2001, on treatment efficacy of inference comprehension in RHD patients. There were two hypotheses tested in the study: first, ”that inferences were deactivated; secondly that the selection of previously generated inferences was slowed and not measurable with the original stimuli” (Blake, 2009). A total of 28 participants were used;
14 had no brain damage NBD, 14 were diagnosed with RHD. The inferencing abilities of both groups were tested by having participants read short stories designated by researchers as having high or low predictive outcomes. Each story contained 10-15 sentences and were presented on a computer. To assess reading speed and the ability to make inferences, the participants were asked to push
