- Ideational Apraxia
- the one where you cannot effectively plan out a series of gestures to complete a motor task - often comorbid with ideomotor
- Ideomotor Apraxia
- the one where you have trouble performing motor tasks upon request - classic body part for tool errors

- Nondeclarative type of memory - typically occurs without conscious mediation
- Incidence
- number of new cases occurring within a specific time period
- Incidental Learning
- learning that occurs without volitional effort
- Inconsistent words

- failure to act or need for cueing despite ability to perform behavior. mesial frontal cortex
- Inner Speech
- experience of hearing one's own words without speaking
- Innervation Apraxia or Limb Kinetic Apraxia
- hand clumsiness that exceeds weakness or tone impairment. more of a pyramidal system disorder than a true apraxia
