The Science of Memory. Superior Autobiographical Memory is a fairly newly discovered phenomenon. A article in PNAS indicates that despite their superior recall, people with hyperthymesia are still susceptible to false memories. Symptoms in early childhood.

Furthermore, other cases of superior memory studied by science are those individuals without ASD that have set a Guinness World Record by memorizing thousands of digits of pi, for example, Rajan Mahadevan, whose memory allowed him to recited 31, decimals of the mathematical constant pi, shows his ability to recite a random sequence of over 40 digits seen by him at the rate of a digit per second during a digit span test [ 86 ], whereas Hideaki Tomoyori, could recite the first 40, digits of pi, had an average visual digit span of 8, but 10 in the auditory digit span [ 87 ]; likewise, Chao Lu established the Guinness World Record at 67, decimals of pi and could remember a mean of 8.

Neurobiology of Learning and Memory.

Surprisingly, the people with stellar autobiographical memory did not score higher on routine laboratory memory tests or when asked to use rote memory aids. A handful of Americans have been identified with this very rare skill but no cases had been reported in the UK until now.

May 22, Last Modified: Finally, other study reported that understanding expressions idioms syndromee associated with more sophisticated and figurative mental images [ 71 ]; consequently, the creation of mental images in people with ASD might be a small successful attempt in order to understand abstract thinking as well as mental states of others, for example, mentalizing deficit in children hypertnymestic autistic disorder was initially tested using the unexpected transfer test of false belief [ 20 ], but both typically developing 3 year olds and children hyperthymestix autism significantly improve on that test when they use thought bubbles, that is, visual representations of mental states [ 7273 ].

Moreover, in another study, a composite group that included children with autistic disorder, both with non-functional verbal language and no spoken language, a significant positive correlation was observed between autism symptoms and scores of an index of declarative memory, which suggests that the imbalance between declarative and procedural memory in ASD might be more important than the mere faulty procedural memory [ 44 ]; such an imbalance might contribute to a global cognitive imbalance.


He concluded that our brains were making “continuous, effortless, video-like recordings” of our experiences, but that these records are not consciously accessible to us.

Thus, the presence of the cognitive deficits predicted by such theories may be considered motivations associated with autism. These data indicate that the digit span tasks are not useful to show the superior memory of hyperthumestic individuals without ASD, such as Hideaki Tomoyori and Chao Lu.

Second, some behaviors from historical figures have been considered autism symptoms [ 15 – 17 ], wyndrome this attitude has been questioned because of doubts regarding whether the socio-cultural context was taken into account [ 18 ]. Apparently he showed an inflexible adherence to nonfunctional routines item A3b.


Both theorical proposals will later be explained in detail. More cases have been identified that are yet to be published. Hyperthymesia is a condition which leads people to be able to remember an synddome large number of their life experiences in vivid detail.

DT has also shown impairment to initiate or sustain conversational interchange and both DT and S recognized that they were verbose and that this affected the conversations with others. It is important to remember the latter because there are authors who may be referring to different types of memory although with the same term, for instance, procedural memory has been described as all implicit memory [ 37 ], whereas, other authors have pointed out that it is only a subtype [ 12363839 ].

Fortunately, although the psychologist who wrote the psychobiographical text to be discussed in the present chapter did not specifically search for autism symptoms, he pointed out several of these symptoms in S.

This is particularly evident in AJ’s case. Blessed and Cursed by an Extraordinary Memory. I don’t make any effort to call memories up; they just fill my mind. Russian psychologist Alexander Luria documented the famous case of mnemonist Hperthymestic Shereshevsky[5] who was quite different from the first hyperrthymestic hyperthymestic known as AJ real name Jill Price in that Shereshevsky could memorize virtually unlimited amounts of information deliberately, while AJ could not — she could only remember autobiographical information and events she had personally seen on the news or read about.

Stephen Wiltshire memorized Rome from the air after a minute helicopter ride hyperthyjestic the city. It is concluded that S most likely had autistic disorder. In addition, the relationship between memory and autism can be hypertyhmestic understood if we reanalyze the life hyperthymestjc this extraordinary individual under the light of the mnesic imbalance theory.

For instance, DT memorized and recited 22, digits of pi and has an jyperthymestic ability to learn to speak new languages [ 9 ]; similary S had the ability to memorize long chains of digits and reproduce several stanzas of The Divine Comedy fifteen years after having read it and despite not knowing Italian.


That day of the anniversary, I just think back to what I was doing, what the weather was like, who I was with, and so-and-so. This is similar to the phrases bread basket instead of home bakery, fifty five instead of grandmother, Annette and Cecile in order to say red and blue, as well as the words Blum instead of a teller of truth and hexagon instead of sixall which were spoken by children described by Leo Kanner, who has always been considered as the first to clinically describe autistic disorder [ 327 ].

Scientists now need to ascertain if and how these brain areas are connected to establish a coherent neurological model for superior autobiographical memory.

Hyperthymesia is a word derived from Greek work hyperthymesis meaning excessive remembering. Uses authors parameter Pages with login required references or sources CS1 errors: In addition, S learned to follow conversations and to understand when his behavior was not tactful [ 1 ]; similarly, a man with autistic disorder named Peter Guthrie and another man with hyperthymesti ASD named Kim Peek, who were used as models to create the character with autistic disorder in the movie Rain Man also showed significant improvement in socialization and communication syndrone the increase in their public activity [ 7778 ].
