Alcohol consumption causes deficits in motor coordination by affecting the cerebellum, which is the main area involved in regulating finer adjustments in movement and motor learning. From Belmeguenai et. al (2008): It has previously been shown that ethanol modulates inhibitory transmission in the cerebellum and affects synaptic transmission and plasticity ...

There are probably too many different possible variables here to make any broad declarations of which specific interval is most effective. There are "between session" improvements in procedural memory, which may result from consolidation of memory especially during sleep. There can also be between session decays as learned skills deteriorate over time. ...

It depends whether the answers are well known facts. If I know well my name, the color of my hair and whether I can ride a bike then semantic memory is used to answer these questions. If I have a doubt whether I can ride a bike, then I may use other types of memory like episodic or even procedural to come up with an answer. Also, I may use episodic memory ...

I second the comments on the question that the question-post looks kind of convoluted. But it seems it all boils down to the question: How does our brain store motor skills without any apparent long-term potentiation or protein synthesis? I personally think the question premise, i.e. "LTP and protein synthesis are not involved in motor learning", is ...

The act of perceiving quantity without actually counting is known as subitizing, and it's something we can all do up to quantities of about 4 (i.e. you can tell how many fingers someone is holding up without counting them, right?). This open access article seems to review the idea quite nicely (although I've only skimmed it), including reference to so ...

Space Repetition is an effective learning method for both procedural and declarative learning. However it cannot replace practicing the skill in real life. Some references: Michael T Ullman, Jarrett T Lovelett Implications of the declarative/procedural model for improving second language learning: The role of memory enhancement techniques, 2018 Adam ...

Looks like when your friend was freshly learning the equations, he was using more of his episodic memory but as he went "used-to" with the equations, he tapped into more of semantic memory. Lets use familiar example. When we recite something, we usually apply the episodic memory. It works much like how we searched a song "along" a tape of ...
