Implicit memory is demonstrated not by conscious recall but by:

1. An implicit memory cannot be reported, so it needs an indirect measure. 2. Implicit memories are learned outside of our awareness and cannot be consciously recalled. 3. Implicit memory is demonstrated in the performance of some task. 4. Faster or more accurate performance is the evidence that the memory exists. 5. Description and recollection both require the conscious access implicit memory lacks. _Source: OpenStax Psychology 2e (CC BY 4.0), Ch 8 'Memory', sections 8.1-8.4_
