With working memory, information—the preceding words in a sentence one is reading, for example—is held in mind so that it can be used in the moment. Sitting on a bike after not riding one for years and recalling just what to do is a quintessential example of procedural memory. The term describes long-term memory for how to do things, both physical and mental, and is involved in the process of learning skills—from the basic ones people take for granted to those that require considerable practice.
How many people have eidetic memory?
Mr. Gordon might want to have formal testing, to see just how good his memory is and in what areas. Then we can debate the nature-nurture question from harder evidence. An experience must be very arousing to an individual for it to be consolidated as an emotional memory, and this arousal can be negative, thus causing a negative memory to be strongly retained. Having a long-lasting extremely vivid and detailed memory for negative events can cause a great deal of anxiety, as seen in post traumatic stress disorders. Individuals with PTSD endure flashbacks to traumatic events, with much clarity. Many forms of psychopathology show a tendency to maintain emotional experiences, especially negative emotional experiences, such as depression and generalized anxiety disorder.
It depends on a slew of factors, including our genetics, brain development and experiences. It is difficult to disentangle memory abilities that appear early from those cultivated through interest and training. Most people who have exhibited truly extraordinary memories in some domain have seemed to possess them all their lives and honed them further through practice. One subject, given any date in history, can recall what the weather was like on said date, personal details of their life at the time, and other news events that occurred at that time. Details of what the subject recalls may be significant to them in some way, but they may not be.

‘Nadia’, who began drawing realistically at the age of three, is autistic and has been closely studied. During her childhood she produced highly precocious, repetitive drawings from memory, remarkable for being in perspective at the age of three, which showed different perspectives on an image she was looking at. For example, when at the age of three she was obsessed with horses after seeing a horse in a story book she generated numbers of images of what a horse should look like in any posture. She could draw other animals, objects, and parts of human bodies accurately, but represented human faces as jumbled forms. Another less thoroughly investigated instance is the art of Winnie Bamara, an Australian indigenous artist of the 1950s.
For grapheme-color synesthesia, studies display greater white matter connections happening between the fusiform gyrus and color area V4 in brains of synesthetes. Autism spectrum disorders contain criteria for diagnosis based on difficulties with social behaviour and communicating with others, amongst other debilitating criteria. Most cases of calendrical calculation involve individuals with IQs that are below average.
