Scientific title | |
Study objectives | To test if flicker can enhance short-term recall in older people. To test if any flicker effects on short term recall are frequently-specific. |
Ethics approval(s) | Not provided at time of registration |
Health condition(s) or problem(s) studied | Signs and Symptoms: Memory |
Intervention | Randomised trial. The intervention is learning and recall of words. A flicker machine will occur on light emitting diodes, the randomisation will be the flicker frequencies. It is thought that specific frequencies (near 10Hz) will enhance recognition and lower and higher frequencies will not. |
Intervention type | Other |
Primary outcome measure | The endpoints of the study will be recognition of words that participants saw during the learning phase. We will test if particular frequencies of flicker that occurred in the learning phase enhance recognition. |
Secondary outcome measures | Not provided at time of registration |
