Abstract
According to Torgesen (1977), LD students deficient performance is not reflective of cognitive processing deficits but of a production deficiency. The student is capable of satisfactory achievement, but does not achieve at such a level due to a passive approach to learning. This
study evaluated these hypotheses using a discrimination learning task and varied reinforcement . LD students were matched with nonhandicapped peers and administered discrimination learning problems with treatment (reinforcement, response cost) and control conditions . Torgesen's hypothesis was not supported. Processing deficits were identified in the LD students ability to code, recode, and recall information compared to regular class students. They also were deficient in benefiting from explicit feedback. All students in the control group demonstrated overall superior performance to those in the reinforcement, response cost condition. The findings were related to influencing behavioral traits and cognitive deficits.
