Impaired vision is common in old age and even more so in Alzheimer’s disease, and this results not only from damage in the association areas of the brain but also from problems in lower-level areas. A major factor in whether visual impairment impacts everyday function is contrast sensitivity.

Visual Language, a term introduced by Robert Horn, refers to "language based on tight integration of words and visual elements". The visual elements include shapes, as well as images (e.g., icons, clip art).
What does this have to do with memory? Well, partly of course, because the appropriate use of images usually makes information more memorable, but visual language has considerably more to offer than that. To appreciate what it is, Horn has examples at http://web.stanford.edu/~rhorn/
Until recent times, attention has always been quite a mysterious faculty. We’ve never doubted attention mattered, but it’s only in the past few years that we’ve appreciated how absolutely central it is for all aspects of cognition, from perception to memory. The rise in our awareness of its importance has come in the wake of, and in parallel with, our understanding of working memory, for the two work hand-in-hand.
As I said in my discussion of different scripts, the Hellenic languages use the Greek alphabet. Here it is. I’m afraid the table is a little complicated, because (a) each letter has a name, which it’s useful to know, and (b) there are some differences in pronunciation between Ancient Greek (which is still a language that people want to learn today), and Modern Greek.
Two large-scale international studies have become established to compare countries' performance in the core subjects of literacy, mathematics and science.
TIMSS: Trends in International Mathematics and Science Study
TIMSS is an international study involving 50 countries that assesses math and science achievement at four year intervals. It has been running since 1995. Students are assessed in the 4th and 8th years of school, and in their final year. The next assessment round will be in 2007.
In 2002, a British study scanned the brains of ten "superior memorizers" — eight leading contenders in the World Memory Championships, and two individuals previously studied for their extraordinary memory accomplishments — all people that had demonstrated truly impressive feats of memory, in terms of the ability to quickly memorize hundreds of numbers or unrelated words. The ten "memory champions" were matched with ten controls, who had no memory capabilities out of the ordinary.
Creating a face-name association
- Select a distinctive feature of the face (nose).
- Select a word or phrase that sounds like the name (con rat for Conrad).
- Create an interactive image linking the distinctive feature with the keyword(s) (a man in a prisoner’s uniform — con — rides a rat that slides down the nose).
To remember the name on seeing the face again, you must:
- Identify the distinctive feature that you used when encoding (nose).
In a recent news report, I talked about a study of older adults that found that their sense of control over their lives fluctuates significantly over the course of a day, and that this impacts on their cognitive abilities, including reasoning and memory.
A New Yorker cartoon has a man telling his glum wife, “Of course I care about how you imagined I thought you perceived I wanted you to feel.” There are a number of reasons you might find that funny, but the point here is that it is very difficult to follow all the layers. This is a sentence in which mental attributions are made to the 6th level, and this is just about impossible for us to follow without writing it down and/or breaking it down into chunks.
