BHS 499-07Memory and Amnesia

Memory Improvement

Memory improvement
Memory Improvement

  • Improving normal memory

    • What works, what does not.

  • Improving memory in those with brain injury.

    • Unlike previously thought, research in the past 15 years shows that memory can be improved.

    • Functioning can also be improved.

What does not work
What Does Not Work

  • Hypnosis and new age approaches:

    • Suggestive Accelerated Learning and Teaching Techniques – SALTT

    • No evidence supporting value of physical relaxation techniques, alternation of active and passive review accompanied by music, suggestions that learning will be fun, songs and rhythms, cooperative learning, frequent self-testing – exam scores 40% below normal.

What works
What Works

  • Organizing the material to be learned.

    • Establishing a link between the items to be learned, so recall of one will cue the others.

    • Tree diagrams that capture a conceptual framework – use table of contents of book.

  • PQ4R method – elaborative rehearsal based on meaning (like PQRST).

    • Preview for structure, then read for answers to questions, repeatedly review.


  • Interactive imagery – bizarre is better.

  • First-letter mnemonics – Real Old Yokels Guzzle Beer In Volume (spectrum).

  • Rhymes – a before e, except after c.

  • Reduction mnemonics – strings of letters represent info in acronym or acrostic.

    • STOMACH – symptoms of anxiety disorder.

More mnemonics
More Mnemonics

  • Method of Loci – picture items in a familiar location.

    • Simonides remembered where guests were sitting after the roof collapsed.

  • Peg-word system – items are linked to a series of pre-learned pegs.

  • Face-name mnemonic – combines imagery with parts of face.

More mnemonics1
More Mnemonics

  • Keyword method – link new vocabulary in a foreign language to some familiar image.

    • Herisson (hedgehog) = hairy son + hedgehog.

  • Yodai mnemonics – think of parts of a binominal as wrestlers in a match:

    • (a + b)(c + d) becomes ac + ad + bc + bd

Memory and practice
Memory and Practice

  • Distributed practice is better than massed practice.

    • Massed practice shows some benefits if there is a lengthy rest period afterward.

    • This doesn’t happen with “cramming”.

  • Lag effect -- spaced repetition helps but not simple repetition.

    • Encoding variability may be occurring, which strengthens memory.


  • Effects of remediation are modest, but very important to those with brain injury.

  • Ignorance about amnesia prevents use of residual memory capacities.

    • Because procedural memory is spared, a person with amnesia can learn to program a computer.

Support memory with devices
Support Memory With Devices

  • Label drawers and cupboards.

  • Put reminder signs up in visible places.

    • Put things by the front door to be taken out.

  • Use a wall chart to show days of week and upcoming events.

  • Use a diary and write notes.

  • Make locations distinctive – paint doors different colors.

More suggestions
More Suggestions

  • Put a flow-chart on the wall with instructions for searching for frequently lost items (e.g., keys).

  • Stick to a regular routine and keep the environment the same.

  • Keep a notepad by the telephone and use speed-dial features.

  • Display photos labeled with names.

External aids
External Aids

  • External cuing devices must provide the reminder as close as possible to the time something is to be done.

  • It should specify what is to be done.

    • Knotted handkerchiefs are useless.

  • Timers with specific messages are ideal.

Is memory like a muscle
Is Memory Like a Muscle?

  • Does repeated practice strengthen memory abilities?

    • No evidence of this – it improves a specific task but it does not generalize.

  • Teaching patients to use mnemonics produces better results.

    • However, patients do not seem to use these spontaneously in everyday life.

Other approaches
Other Approaches

  • Expanded spaced retrieval – gradually expanding the time between spaced rehearsals showed improvement.

  • Vanishing cues – start by presenting prompts which gradually fade away.

    • Initially seemed promising but tests show no advantage over rote rehearsal.

Memory groups
Memory Groups

  • People find out they aren’t the only ones having difficulty, gain support from sharing their problems with others.

  • No direct benefit in improving memory.

  • Members share their tips for coping with daily life, which is very useful.
