| Define ideomotor apraxia. | Loss of ability to do a motor task on command, but can be accomplished automatically. | |
| Define ideational apraxia. | Loss of ability to use common objects related to their meaning (combing hair with fork). | |
| Define body scheme. | Integrating of visual, proprioceptive, and tactile input that makes up the neural postural model. | |
| Define unilateral neglect. | A type of body scheme deficit that affects the awareness of half of the body and space contralateral to the side of the stroke. | |
| What are the two categories that make up tactile object knowledge? | Stereognosis and finger gnosia. | |
| Define sterognosis. | Ability to identify objects through the sense of touch. | |
| Define finger gnosia. | Ability to identify the finger being touched. | |
