Final answer:
Echoic memory refers to auditory sensory memory, not motor skills, and is therefore not related to echoic memory, making the statement false. The term engram is used to describe a physical trace of memory, while flashbulb memory denotes an intensely vivid recollection of an important event.
Step-by-step explanation:
Echoic memory refers to the branch of sensory memory specific to retaining auditory information, and is not about motor skills. Therefore, the notion that echoic memory pertains to memory about motor skills is false. Motor skills are associated with procedural or implicit memory, which involves the learning of tasks that can be performed without conscious awareness of the learned process and is typically stored and processed by the cerebellum.
An example of a physical trace of memory is known as an engram. This term refers to a hypothetical means by which memory traces are stored as biophysical or biochemical changes in the brain in response to external stimuli.
A highly vivid and clear recollection of a significant event is termed a flashbulb memory. This type of memory is often retained in great detail and with heightened emotions, making it easy to recall for long periods of time.
