Answer:
Our sensorimotor system appears to be influenced by the recent history of our movements. Repeating movements toward a particular direction is known to have a dramatic effect on involuntary movements elicited by cortical stimulation—a phenomenon that has been termed use-dependent plasticity. However, analogous effects of repetition on behavior have proven elusive. Here, we show that movement repetition enhances the generation of similar movements in the future by reducing the time required to select and prepare the repeated movement. We further show that this reaction time advantage for repeated movements is attributable to more rapid, but still flexible, preparation of the repeated movement rather than anticipation and covert advance preparation of the previously repeated movement. Our findings demonstrate a powerful and beneficial effect of movement repetition on response preparation, which may represent a behavioral counterpart to use-dependent plasticity effects in primary motor cortex.

I think that’s right
Explanation:
Auditory processing disorder (APD), also known as Central Auditory Processing Disorder (CAPD), is a condition that impacts the brain’s ability to filter and interpret sounds. People with APD can hear, but have a hard time receiving, organizing, and processing auditory information. APD often emerges in childhood.
While APD isn’t too well known, it is estimated that 7 percent of children have some type of auditory processing difficulty. Do everyday instructions, requests, and questions seem to bounce off your child? Like he or she is living in a bubble that is impenetrable by oral directions? If your child responds most of the time with a blank stare or “Wait, what?” then you know what we’re talking about.
Or perhaps you’ve noticed this yourself — that the world feels “garbled,” like you’re listening to a cell phone call with the signal cutting in and out?
