Groundbreaking Research in Aphasia

Did you know that the earliest research on aphasia by Dr. Murray Sidman and his colleagues began in Massachusetts in the 1960s to treat persons with brain injury with severe aphasia?

These important papers contain data that are more understandable in view of the later work explicitly on equivalence relations.

Murray & Rita Sidman

Behavior Analysis and Aphasia

“In addition to instances of word-reference equivalence that can be culled from everyday experience, we have seen some striking examples in some of our laboratory studies of aphasic patients. Although these observations were published in the same year as our first equivalence paper, they actually antedated that work by more than ten years, but even after we had started our direct experimental attack on equivalence phenomena, the significance of the earlier data took a while to sink in. Those data should have made us take a closer look.” (Sidman, 1994: From Equivalence Relations and Behavior: A Research Story)

The significance of this early research can be seen in the collection of Sidman’s research below.
