We all know that lack of sleep makes us more prone to attentional failures, more likely to make mistakes, makes new information harder to learn, old information harder to retrieve ... We all know that, right? And yet, so many of us still go to bed too late to get the sleep we need to function well. Of course, some of us go to sleep early enough, we just can’t get to sleep fast enough, or are prone to waking in the night. (Personally, I can count the times I’ve slept through the night without waking in the last fifteen years on my fingers).

What mnemonics are, and what they are for
Aids to memory such as acronyms, rhymes, linking information by creating visual images or making up a story, are called mnemonics. Mnemonic strategies have been recommended as appropriate for remembering the following types of information:
Humans are the animals that manipulate their cognitive environment.
Back in 2010, I read a charming article in the New York Times about a bunch of neuroscientists bravely disentangling themselves from their technology (email, cellphones, laptops, …) and going into the wilderness (rafting down the San Juan River) in order to get a better understanding of how heavy use of digital technology might change the way we think, and whether we can reverse the problem by immersing ourselves in nature.
Prevalence
Vascular dementia, as its name suggests, is caused by poor blood flow, produced by a single, localized stroke, or series of strokes.
It is the second most common dementia, accounting for perhaps 17% of dementias. It also co-occurs with Alzheimer's in 25-45% of cases. Although there are other types of dementia that also co-occur with Alzheimer's, mixed dementia generally refers to the co-occurrence of Alzheimer's and vascular dementia.
Introduction
In 1997, the U.S. Congress asked the Director of the National Institute of Child Health and Human Development (NICHD) at the National Institutes of Health, in consultation with the Secretary of Education, to convene a national panel to assess the effectiveness of different approaches used to teach children to read. For over two years, the National Reading Panel reviewed research-based knowledge on reading instruction and held open panel meetings in Washington, DC, and regional meetings across the United States.
People are poor at assessing their own memory
One thing research seems to show rather consistently is that, for older adults in particular, beliefs about one's own memory performance have little to do with one's actual memory performance¹. People who believe they have a poor memory are usually no worse at remembering than those who believe they have a good memory.
A general distinction you can make is that between:
- direct study, and
- learning from context
Direct study is more important when you're learning a non-cognate language. It's also more important in the initial stages of learning a language. Learning from context is particularly useful for cognate languages.
Of course learning a language requires both approaches, but the relative proportions will vary.
Having trouble sleeping is perfectly normal, especially as we age. It’s estimated that half of those older than 55 have trouble getting to sleep or staying asleep.
What to do if your sleep is poor
Let’s start with the easiest situation: you’re not getting enough sleep because you wilfully go to bed too late to achieve your needs.
Knowing a number of effective strategies for reading and note-taking, practicing and memorizing, is vital, but it's not the whole story. There is also a category of strategies we might term 'support' strategies. These include strategies aimed at setting goals, managing time and effort, and monitoring your performance and progress. In study, these come under the concept of self-regulation, which is related to the more general concept of metamemory.
