Hyperphantasia is the condition of having extremely vivid mental imagery. [1] It is the opposite condition to aphantasia, where mental visual imagery is not present. [2] [3] The experience of hyperphantasia is more common than aphantasia [4] [5] and has been described as being "as vivid as real seeing". [4]
In 2018, a study analyzing the visual working memory of a person with aphantasia found that mental imagery has a "functional role in areas of visual cognition, one of which is high-precision working memory" and that the person with aphantasia performed significantly worse than controls on visual working memory trials requiring the highest ...
[15] [16] Similarly, increasing the duration of a stimulus available in a reaction time task was found to produce slightly faster reaction times to visual [15] and auditory stimuli, [17] though these effects tend to be small and are largely consequent of the sensitivity to sensory receptors. [8]
It mainly causes vision changes, ataxia and impaired memory. [2] The cause of the disorder is thiamine (vitamin B 1) deficiency. This can occur due to Wernicke encephalopathy, eating disorders, malnutrition, and alcohol abuse. These disorders may manifest together or separately. WKS is usually secondary to prolonged alcohol abuse.
Agnosias are sensory modality specific, usually classified as visual, auditory, or tactile. [2] [3] Associative visual agnosia refers to a subtype of visual agnosia, which was labeled by Lissauer (1890), as an inability to connect the visual percept (mental representation of something being perceived through the senses) with its related semantic information stored in memory, such as, its name ...
The difference in memory between normal aging and a memory disorder is the amount of beta-amyloid deposits, hippocampal neurofibrillary tangles, or amyloid plaques in the cortex. If there is an increased amount, memory connections become blocked, memory functions decrease much more than what is normal for that age and a memory disorder is ...
For instance, the auditory images that are remembered are usually 10–20 seconds long, however remembering facts or scenes do not necessarily hold time stamps like auditory images do. This insight would hold relevance on understanding the relationship of music and memory. [27] Auditory imagery can be studied using tonal stimuli.
As contemporary researchers use the expression, mental images or imagery can comprise information from any source of sensory input; one may experience auditory images, [7] olfactory images, [8] and so forth. However, the majority of philosophical and scientific investigations of the topic focus on visual mental imagery.
