=== Tactile test ===

In a second experiment, Sperry and Gazzaniga placed a small object in the subject's right or left hand, without the subject being able to see (or hear) it. When the object was placed in the right hand, the isolated left hemisphere perceived the object and could easily describe and name it. However, when the object was placed in the left hand, the isolated right hemisphere could not name or describe the object. Questioning this result, the researchers found that the subjects ''could'' later match it from several similar objects; tactile sensations limited to the right hemisphere were accurately perceived but could not be verbalized. This further demonstrated the apparent location (or lateralization) of language functions in the left hemisphere.{{citation needed|date=December 2020}}
