This report describes AJ, a woman whose remembering dominates her life. Her memory is “nonstop, uncontrollable, and automatic.” AJ spends an excessive amount of time recalling her personal past with considerable accuracy and reliability. If given a date, she can tell you what she was doing and what day of the week it fell on. She differs from other cases of superior memory who use practiced mnemonics to remember vast amounts of personally irrelevant information. We propose the name… 
A review of highly superior autobiographical memory
In the results of behavioral and neuroanatomical studies it was postulated that HSAM and OCD could a common underlying mechanism but no definitive conclusion could be reached on this issue.
Neuropsychological investigation of "the amazing memory man".
A newly discovered HSAM case who has extraordinary memory for a wider range of material than has heretofore been described, andStructural brain imaging in MM reveals atypical anatomy in his left temporal lobe, and functional neuroimaging suggests greater than usual connectivity of the left hippocampus with premotor, prefrontal and retrosplenial cingulate cortex.
Behavioral and neuroanatomical investigation of Highly Superior Autobiographical Memory (HSAM)
False memories in highly superior autobiographical memory individuals
It is suggested that HSAM individuals reconstruct their memories using associative grouping, as demonstrated by a word-list task, and by incorporating postevent information, as shown in misinformation tasks, and that malleable reconstructive mechanisms may be fundamental to episodic remembering.
Highly Superior Autobiographical Memory: Quality and Quantity of Retention Over Time
The data suggest that HSAMs experience normal encoding, yet enhanced consolidation and later recall of autobiographical events, with remarkable consistency following a 1-month delay.
A cognitive assessment of highly superior autobiographical memory
Interestingly, HSAM participants recalled details of their own experiences far better than those experiences that the experimenter shared with them, providing additional evidence that HSAM involves, relatively selectively, recollection of personal, autobiographical material.
Two types of event memory
The interesting results of Patihis et al. (3) and previous papers on people with highly superior autobiographical memory (HSAM) (4, 5) call into question part of Tulving’s claims.


One man's memory: A study of a mnemonist
This paper reports a systematic study of a man (T.E.) with astonishing mnemonic skills. After a brief description of his most favoured mnemonic technique, the ‘figure alphabet’, his performance and

In this reworking of the 'episodic memory' concept autobiographical memory provides the instantiating context for sensory-perceptual episodic memory.
Toward a theory of episodic memory: the frontal lobes and autonoetic consciousness.
Evidence supports a preliminary theory of episodic remembering, which holds that the prefrontal cortex plays a critical, supervisory role in empowering healthy adults with autonoetic consciousness-the capacity to mentally represent and become aware of subjective experiences in the past, present, and future.
A date to remember: the nature of memory in savant calendrical calculators.
A general mnemonic advantage cannot explain savant date calculation skills and the savants are suggested to develop a structured calendar-related knowledge base with the process of calculation utilizing the interrelations within this knowledge store.
The Recovery of Unconscious Memories: Hypermnesia and Reminiscence
Integrating literature from all areas of psychology, this book includes historical accounts, analysis of experiments and treatment topics, providing a comprehensive scientific account of memory and
Memory for the time of past events.
Laboratory and autobiographical studies of normal adults'memory for the time of past events are reviewed, and the main phenomena that have been discovered are described. A distinction is introduced
The memory structure of autistic idiot-savant mnemonists.
The memory organization of six autistic mnemonists was investigated and provided some evidence that the material of special interest to the subjects, in the present instance bus numbers, was stored in memory in a categorized form.
Routes to remembering: the brains behind superior memory
These results illustrate how functional neuroimaging might prove valuable in delineating the neural substrates of mnemonic techniques, which could broaden the scope for memory improvement in the general population and the memory-impaired.
Recognition memory and decision processes: A meta-analysis of remember, know, and guess responses
A meta-analysis of proportions of remember, know, and guess responses was carried out on observations from 86 experimental conditions in 23 different recognition memory experiments, finding that it was guessing, rather than knowing, that was most strongly correlated with overall response criteria.
