New direction for cognitive training in the elderly

October, 2012

A pilot study suggests declines in temporal processing are an important part of age-related cognitive decline, and shows how temporal training can significantly improve some cognitive abilities.

Here’s an exciting little study, implying as it does that one particular aspect of information processing underlies much of the cognitive decline in older adults, and that this can be improved through training. No, it’s not our usual suspect, working memory, it’s something far less obvious: temporal processing.

In the study, 30 older adults (aged 65-75) were randomly assigned to three groups: one that received ‘temporal training’, one that practiced common computer games (such as Solitaire and Mahjong), and a no-activity control. Temporal training was provided by a trademarked program called Fast ForWord Language® (FFW), which was developed to help children who have trouble reading, writing, and learning.

The training, for both training groups, occupied an hour a day, four days a week, for eight weeks.

Cognitive assessment, carried out at the beginning and end of the study, and for the temporal training group again 18 months later, included tests of sequencing abilities (how quickly two sounds could be presented and still be accurately assessed for pitch or direction), attention (vigilance, divided attention, and alertness), and short-term memory (working memory span, pattern recognition, and pattern matching).

Only in the temporal training group did performance on any of the cognitive tests significantly improve after training — on the sequencing tests, divided attention, matching complex patterns, and working memory span. These positive effects still remained after 18 months (vigilance was also higher at the end of training, but this improvement wasn’t maintained).

This is, of course, only a small pilot study. I hope we will see a larger study, and one that compares this form of training against other computer training programs. It would also be good to see some broader cognitive tests — ones that are less connected to the temporal training. But I imagine that, as I’ve discussed before, an effective training program will include more than one type of training. This may well be an important component of such a program.

Cheaper way to do a great study

We could give people Apps which record how long was spent on each game / how many times played etc. Another App could actually do the memory tests and send the details back to us! Many some university under-grad could do this as their thesis? The results could be really useful if enough people take part. With software you could have many people taking part for no extra cost.

Re: Cheaper way to do a great study

You're absolutely right, Andrew. The technologies around now make it so much easier to do this kind of research.
