An example system can consist of a light source (generally a laser or a lamp), a controller for the amount of light that enters, a guide for the light, and a delivery system. Often, the design function in such a way that a medium is met between the diffusing light that may cause additional, unwanted photolysis and light attenuation; both being ...
The history of light therapy can be traced back to ancient Egypt and India, where therapy with natural sunlight was first used to treat leucoderma. [3] In the 1850s, Florence Nightingale's advocacy of exposure to clean air and sunlight for health restoration also contributed to the initial development of light therapy for treatments. [4]
Light therapy, also called phototherapy or bright light therapy is the exposure to direct sunlight or artificial light at controlled wavelengths in order to treat a variety of medical disorders, including seasonal affective disorder (SAD), circadian rhythm sleep-wake disorders, cancers, neonatal jaundice, and skin wound infections.
The dual-code theory, created by Allan Paivio in 1971, is the theory that we use two separate codes to represent information in our brains: image codes and verbal codes. Image codes are things like thinking of a picture of a dog when you are thinking of a dog, whereas a verbal code would be to think of the word "dog". [ 31 ]
For example, a patient “L.E.” suffered brain damage and her ability to draw from memory was severely diminished, whilst her spatial memory remained normal. Other patients represent the opposite, where memory for colors and shapes is unaffected but spatial memory for previously known places is greatly impaired. [ 30 ]
Cognitive reframing can be useful in many ways, such as when trying to improve memory, reduce test anxiety, and helping parents and children cope with disabilities. For example, people with memory problems were told that their memory could be improved by shifting their perspective on their problem. After receiving treatment, their memory ...
The founder promoted the therapy for the treatment of PTSD, and proponents employed untestable hypotheses to explain negative results in controlled studies. [9] EMDR has been characterized as a pseudoscientific purple hat therapy (i.e., only as effective as its underlying therapeutic methods without any contribution from its distinctive add-ons).
However, eidetic memory is not limited to visual aspects of memory and includes auditory memories as well as various sensory aspects across a range of stimuli associated with a visual image." [10] Author Andrew Hudmon commented: "Examples of people with a photographic-like memory are rare. Eidetic imagery is the ability to remember an image in ...
