Fig.1 Does alcohol have a permanent effect on the brain?
The answer is 'yes', though of course it is dependant on many variables: binge drinking is bad, like a blow to the head. This comprehensive heavy-weight article I Googled, 'Alcohol's Damaging Effects on the Brain' satisfies my initial curiosity, then the above shocking image catches my eye.
Dare I ask if we know any child who clearly showed such facial traits?
Far too late to do anything about it though.
After this paper like post from the National Institute of Alcohol Abuse and Alcoholism I eventually start looking to chase up a few references (the very best way to satisfy you curiosity and layer detail onto the ideas you are gathering) when I read that 'memory formation and retrieval are highly influenced by factors such as attention and motivation'.
This quote from Kensinger E A et al in the Journal of Neuroscience 2003. Title: What neural correlates underlie successful encoding and retrieval? Not Found in the OU Library so I cut and paste into Google Scholar and there it is to download as a PDF.
It is not surprising that scientific research shows (not speculation) that distraction diminishes attention and therefore retention, nor surprising that a low level distraction has less impact than a high one.
Does a teenager (or any of us) supposedly doing homework while
a) interacting on Facebook
b) answering text messages
c) streaming a movie and/or
d) playing a video game
... complete a task half as well than when focused?
Exam conditions aren't just best for exams:
turn off the radio and phone, shut the door, put up a 'Do Not Disturb' sign, give yourself a set period of time in which to concentrate ... and reward yourself at the end of it (not with alcohol though).
Why we all need a 'room of our own'? (Even if you have to wait until someone else vacates it).
Better an hour studying when motivated and focused, then three hours while streaming a movie, or answering email?
