Widely cited gender differences in cognition

It is clear that there are differences between the genders in terms of cognitive function; it is much less clear that there are differences in terms of cognitive abilities. Let me explain what I mean by that.

It's commonly understood that males have superior spatial ability, while females have superior verbal ability. Males are better at math; females at reading. There is some truth in these generalizations, but it's certainly not as simple as it is portrayed.

The limitations of working memory have implications for all of us. The challenges that come from having a low working memory capacity are not only relevant for particular individuals, but also for almost all of us at some points of our lives. Because working memory capacity has a natural cycle — in childhood it grows with age; in old age it begins to shrink. So the problems that come with a low working memory capacity, and strategies for dealing with it, are ones that all of us need to be aware of.

How the keyword method works

The keyword method has been especially pushed as an effective strategy for learning foreign vocabulary. It is presumably equally valuable for extending your native-language vocabulary and learning technical jargon, and has also been used successfully to teach social studies facts (e.g., the products of a country; capital cities), science facts (e.g., chemical reactions, parts of the skeletal and nervous systems) and the names and faces of people.

There are two stages to the method:

The method of loci or place method

This is the classic mnemonic strategy, dating back to the ancient Greeks, and is (as evident from its continued use over 2500 years) an extremely effective strategy for remembering lists.

There have been quite a few studies looking into the possible benefits of omega-3 fatty acids and fish (a good source of the oils), particularly for older adults. Several large studies have found that regular intake of oily fish is associated with lower rates of dementia, and some evidence that eating fish regularly slows the rate of 'normal' age-related cognitive decline.

I was listening on my walk today to an interview with Edward Tufte, the celebrated guru of data visualization. He said something I took particular note of, concerning the benefits of concentrating on what you’re seeing, without any other distractions, external or internal. He spoke of his experience of being out walking one day with a friend, in a natural environment, and what it was like to just sit down for some minutes, not talking, in a very quiet place, just looking at the scene.

Do experts simply know "more" than others, or is there something qualitatively different about an expert's knowledge compared to the knowledge of a non-expert?

While most of us are not aiming for an expert's knowledge in many of the subjects we study or learn about, it is worthwhile considering the ways in which expert knowledge is different, because it shows us how to learn, and teach, more effectively.

This post is the second part in a four-part series on how education delivery is changing, and the set of literacies required in today’s world. Part 1 looked at the changing world of textbooks. This post looks at the oral equivalent of textbooks: direct instruction or lecturing.

Let’s talk about the cognitive benefits of learning and using another language.

In a recent news report, I talked about the finding that intensive learning of a very novel language significantly grew several brain regions, of which two were positively associated with language proficiency. These regions were the right hippocampus and the left superior temporal gyrus. Growth of the first of these probably reflects the learning of a great many new words, and the second may reflect heavy use of the phonological loop (a part of working memory).

Movement with Meaning: A Multisensory Program for Individuals in Early-Stage Alzheimer's Disease

Those of us in the field of dementia care are reexamining our philosophical beliefs and exploring practical, hands-on approaches in our relationships with individuals living with Alzheimer's disease. We are creating innovative programs and developing a new framework for preserving the emotional health, autonomy, and dignity of those who need us to walk hand in hand with them, witnessing the process of their experiences with empathy and respect.
