The Effect Of Color on Memory Retention: Visual Stimulation for Alzheimer’s Disease and Dementia
Aside from the brain, the eye is the next most complex organ in the human body. It should come as no surprise that the brain an eye are intricately connected. Most people are unaware of the profound effect color has on behavior.
Every color has a unique effect on individuals and stimulates various responses. Have you noticed how fast food companies use red, yellow and orange colors in their restaurants and product packaging? It has been shown that these colors are found to be helpful in increasing appetite.
If you find that your loved one suffering from Dementia or Alzheimer’s has trouble eating, do what we do here at Mountain View Centers … make the plate of food stand out with color.
A research by the University of British Columbia has proven that blue color enhances creativity whereas; the color red helps to be focused and has a positive effect on memory.
The ‘ageing eye’
As people age, many changes occur which affect vision and colour perception. The thickening and yellowing of the lens alters the way colour is perceived. As a result older people experience:
- A reduction in contrast perception ability, resulting in difficulty differentiating between subtle changes in the environment such as carpets and steps.
- A reduction in the perceived saturation or vividness of colours (i.e chroma). For example reds start to look like pinks
- A reduced ability to discriminate blue colours.
The lightness of a color (tint and shade) is an important factor in being able to discriminate between colors. Color preference ratings were similar for people with dementia that is, blue, red and green were most preferred, in that order. All people find it easier to distinguish between colors in the red/yellow range, and harder to distinguish colors in the blue/green range.
