Tag Archives: Fine motor task – Visual place memory Synaesthesia

Is there any particular feeling that follows synaesthesia?

Nope. The train of thought and life in general continues on, just as before. Synaesthesia is just another kind of thought, or a fleeting memory, in fact, I’ve argued here that synaesthesia is an exotic variety of memory or learning (I’ve got to learn the difference between the two, or remember the difference between the two). I experience some types of synaesthesia that are so much a part of my normal train of thought and so brief that I mostly don’t notice that they ever happen. I’ve only really figured out that they are a thing when I systematically set out to make written records of them on any available bit of paper, just after they happened, during my everyday activities.

Definitely synaesthesia, including mirror-touch synaesthesia, something to do with this

I’d never heard of autonomous sensory meridian response until a few moments ago when I was half-watching the arts tv show The Mix, with a story on it about an upcoming show Blacklist by SuppleFox scheduled for the Dark Mofo arts festival at Tasmania’s always-interesting MONA (Museum of Old and New Art). Synaesthesia is a theme that has already been explored at MONA.

I definitely think some of this ASMR bizzo is one or another type of synaesthesia, and I’m also sure there are folks out there who will insist it impinges on the territory of the various sensory hyper-sensitivity conditions identified by some OTs, and also the controversial territory of autism. I do wonder what the point is, of trying to make art out of neurologically-based phenomena that are highly individualised. Most people are not synaesthetic, at least to the degree that they could score a passing grade in the Synaesthesia Battery, so I’ve got to wonder what all those non-syanesthetes get out of art that explores or uses synaesthesia. If most people do not experience touch sensations in response to watching people running fingers through hair or suffering injuries, and most people get no particular thrill from listening to whispering (which is white and whispy in appearance), then I suspect that art based on these effects will have a limited appeal. It’s quite a conversation-starter, nevertheless.

I find it interesting that in the ABC story about Blacklist video of a person buttering toast is shown, because when I butter toast or scones that triggers a type of synaesthesia in which I “see” in my mind’s eye scenes of places that I have not visited for many years or decades, just as I saw them then. I suspect that for these ASMR people their trigger would be the sound of toast being scraped, while for me the trigger is definitely the performance of the fine-motor movements involved in buttering, with a specificity to such a fine degree that buttering crumbly scones triggers a different set of scenes than buttering toast.

I also find it interesting that one scene in the story, in which a woman lies in a tank of water holding her breath, reminds me of some scenes from one of my absolute favourite films, Mad Detective, in which the main character who is labelled as mad is subversively depicted in the film as strangley gifted with extraordinary powers of perception and insight into the characters and motivations of others (he “sees” their “inner selves”). The mad detective creates experiences for himself that simulate the experiences of murder victims, with the aim of triggering some kind of supernatural shared memory or insight into the facts of the crime. In one scene he has himself rolled down stairs in a suitcase and in another he gets a colleague to bury him in a forrest. The relationship between experiential or sensory triggers and evoked memories or experiences is interestingly similar to the way many of my more interesting varieties of synaesthesia operate, and as a super-recognizer, I’ve got to be fascinated by a protagonist in a movie who has a rare gift of special knowledge about other people. The plot of the movies seems to be very much based on an insight that only a synaesthete would truly understand; that the only way to experience a synaesthesia concurrent (which is usually clearly some kind of memory) is to trigger it by experiencing, first-hand, the exact and specific synaesthesia inducer. It cannot be imagined. It cannot be triggered by any other means. It cannot be experienced by a non-synaesthete, or by a synaesthete who does not have exactly the same synaesthesia association. When the mad detective places himself into extreme situations, he seems to be operating under the same rule; that only the exact same experience can unlock a memory or an insight through perception. I can’t believe that this movie was made without a major contribution from a synaesthete. Another big hint that the main character is some kind of synaesthete is the thing at the start of the film with the highly spontaneous self-amputation of an ear. I hasten to point out that this is not a common behaviour among synaesthetes, and the millions of synaesthetes in the world are generally pretty sane people, but there is one famous person from the past who was unhinged and also one of us. There is plenty of evidence in the archived correspondences of Vincent van Gogh that he was a synaestete. He was always writing about concepts or experiences corresponding with colours. You can’t claim to know the arts without knowing a thing or two about synaesthesia, and synaesthetes.

Too exciting! Nobel Prize awarded for research on stuff that I’ve been writing about here

Visual recognition of places or scenes, mental navigation, a sense of place and the normal mental memory function that is the basis for the “method of loci” memory technique are some of the interesting psychological subjects that I have written about here, and it appears that my interests very much overlap with the areas of research pioneered by John O’Keefe and May-Britt and Edvard Moser, all winners of the 2014 Nobel Prize for Medicine. This team spent a great part of their careers doing research on rats, and their discoveries include grid cells and “place cells” which are nerve cells in the hippocampus that only activate when the rat is in a specific physical location. I’m not clear whether the grid cells and the place cells are the same thing or not. Read about their fascinating and important research here.

I’m feeling very frustrated right now as I am sure that somewhere in this blog I’ve written a description of an experience that I occasionally have while travelling in a train in unfamiliar lines or at night, in which it appears that two different mental navigational systems in my brain go “out of sync” causing a temporary sense of confusion about where I am. One of these navigational systems is based on visual perception of scenes while the other is based on a body-centred, visceral, embodied, spatial, sense of direction, and the common language “spoken” between these two systems is the visual memory of scenes, (which is of interest in my case because this function is encoded in pretty-much the same part of the brain as face memory, and I’m a super-recognizer). Normally the visual perception of scenes system informs and regularly updates the directional sense system, and the directional system accesses a sequentially-encoded system of visual memories of places and then sends predictions about expected scenery back to the visual system. Sometimes when visual scene recognition operates at the edges of ability and fails to provide input to or misinforms the directional system, the directional system works in an uncertain and speculative way, and at times is confronted with input of visual scenes that do not fit the predictions of expected scenery sent from the scene memory bank. This is the “spin-out” moment. Following this head-spinning moment of confusion is a sense of “Where the f*** are we?”, and my sense of navigation will either be reset from a combination of conscious knowledge of direction combined with visual memories of scenes or fresh comprehensible visual input. This is my interpretation of these types of experiences, which I believe are interesting and can inform us about normal mental navigation. I am very conscious of visual memories of scenes because I experience a number of types of synaesthesia in which these memories are either inducers or concurrents. I believe I am the first person in the world who has taken the time to write and publish full descriptions of these experiences, here at this blog. I have asserted that one of these types of synaesthesia is the same or very similar to the very powerful and ancient method of loci memory technique, which involves activation of a number of parts of the human brain, including the hippocampus.

Oops, I followed a wrong turn in the path of scientific progress

There I was getting excited about research into embodied cognition and I was observing how much it seemed to resemble types of synaesthesia that I experience which are triggered by spatial experience or movement, and I read a book about embodied cognition and was very impressed, but then I read the below article in Science about projects with the aim of replicating some influential studies in psychology and social psychology, some of them about embodied cognition, and apparently a number of studies that were thought to demonstrate embodied cognition and also behaviour priming were re-studied but the findings were not replicated. These recent studies attempting to replicate classic studies in social psychology were published in the latest issue of the journal Social Psychology. Even worse, one pioneer in the area of embodied cogniton is facing accusations of research misconduct, according to the Science article. Could the field of embodied cognition be saved from oblivion by looking for effects that can be replicated, and then considering them a possible variants of synaesthesia?

Visual memory of chore – concept of true story synaesthesia

As I opened the lid of the clear plastic seed-sprouter at my kitchen sink and saw the just-sprouting greenish mung beans, the unpleasant memory of the facts of the story covered by last night’s Four Corners current affairs television show jumped into my mind unbidden. Last night I had been picking out dead brown non-sprouting mung beans from the healthy beans after they had been soaking for hours to start the sprouting process, the kind of dull and repetitive chore that I often try to make less boring by listening to the television or radio while I’m working. In the process of performing this chore last night the content of the television show that I had listened to had become wedded with the visual image of the sprouting beans laying on the tray of the seed sprouter. I think the neuroscience term for this might be “binding”. The fact that these two logically unrelated experiences had become permanently connected in my brain and my mind was unknown to me until the sight of the beans in the sprouter was seen again this afternoon, involuntarily and instantly triggering a complex concept in my mind that has nothing to do with beans or sprouting. The way this variety of synaesthesia operates has similarities with the operation of a number of other varieties of synaesthesia that I have previously written about at this blog: the Proust Phenomenon, fine motor task – visual place memory synaesthesia, concepts associated with visual memories of scenes, involuntary method of loci memorization (IMLM) and arguably The Strange Phenomenon. This type or a similar type of synaesthesia has been experienced by me many times in the past after the synaesthesia associations have been formed while I was doing handcrafts while listening to television shows or radio. An example would be my remembering one year’s winner of the Eurovision Song Contest when I look at the hand-made quilt on our child’s bed which I worked on while we were tuned into the song contest finals on TV. Turkey should win more often – they always make interesting music with a great beat.

Just discovered that there are psychologists who study involuntary autobiographical memories (IAMs)

Involuntary autobiographical memories are of special interest to me because I experience visual memories of scenes, a face, complete personalities of real people from my past and autobiographical memories of learning about specific concepts as synaesthesia concurrents, which means that when I encounter experiences that trigger these synaesthesias I involuntarily experience one of these types of IAMs. So, one could say that at least for me the IAM experience is just another broad category of synaesthesia that I experience. So does that mean that the IAM experiences of people thought to not be synaesthetes are in fact also synaesthesia, or are the resemblances between our experiences just superficial? At this blog I have previously described types of synaesthesia experienced by me that are triggered by performing over-learned fine motor movements (housework and grooming manual chores) which have concurrents that are visual memories of scenes of locations or learned concepts. I have also noted that my random uncontrolled thoughts become more creative and fluent with greater accessibility to concepts and memories while I am performing spatial-movement tasks such as showering or driving or walking. So I was rather astounded when I read this in a paper about IAMs from The Psychologist from a year ago:

“IAMs occur spontaneously without any deliberate intention to recall anything. In fact they are most likely to occur when individuals are engaged in regular, automatic activities that are not attentionally demanding, such as walking, driving or eating.”

Actually, these activities are attentionally demanding, but maybe not demanding on the conscious, verbal parts of the brain. I think the thing that really matters about these tasks are that they are spatial-motor tasks which activate the parietal lobe, which just also happens to be a region of the brain that plays a central role in many cases of synaesthesia. My theory is that there is a category of IAMs which are a subtype of synaesthesia in which experiences that are obviously autobiographical memories are the synaesthesia concurrents and motor-spatial processes are the synaesthesia inducers. I have also previoiusly put forward the theory that synaesthesia concurrents are actually memories of one or another type, rather than randomly and mysteriously generated experiences or sensory experiences.

I believe that IAMs cannot be studied or understood without the study and knowledge of synaesthesia, because many instances of IAMs are synaesthesia of one type or another, and the whole IAM phenomenon is very similar to synaesthesia in the way it works. Despite my observations, in the paper in The Psychologist by Bradley, Moulin and Kvavilashvili I could find no mention of synaesthesia at all. I think there is a lot of work to be done in this area of research.

Thank you.

The idea that Benson’s syndrome or posterior cortical atrophy or PCA, a variety of dementia, is caused or develops in a way that can be seen as the opposite of the synaesthesia linked with exceptional visual memory and literacy skills that runs in my family (this idea has been explored previously in this blog).

The idea that the above cited states develop or are caused in a way that makes them seem like opposites because they both affect the same or similar areas of the brain, but in opposite ways.

The idea that the above described process happens because Benson’s syndrome and our variety of synaesthesia are both mediated by the same or similar natural chemical or cells or biological agent in the brain, one caused by high levels of the mystery substance and the other caused by low levels (a hypothesis that I briefly suggested in January 2011).

The idea that one of the many known or unknown elements of the immune system that impact brain development is the mystery substance referred to above (a hypothesis that I briefly outlined in 2012).

The (implied in above ideas) idea of the immune hypothesis of synaesthesia. (This idea was first published by me in 2012 in a blog post archived here, was I believe plagiarized in 2013 here, and was the subject of my plagiarism claim here.)

The idea that one or more of the complement immune chemicals is the  mystery substance referred to above.

The idea that the C3 complement immune chemical  is the  mystery substance referred to above.

The idea that synaesthesia is linked with one or maybe more immune diseases or conditions caused by low levels of complement.

The idea that genes for synaesthesia stay quite common in the gene pool because of some associated cognitive advantage (probably superior memory) that balances out any disadvantages caused by deficiencies in the immune system.

The idea that some or many people unintentionally experience a memory process that operates in a similar way to the method of loci memory technique in their everyday lives, unintentionally forming long-term associations between individual learned concepts and individual visual memories of scenes (I have named this phenomenon Involuntary Method of Loci Memorization or IMLM).

The idea that IMLM operates in such a similar way to synaesthesia that one could argue that it is a type of synaesthesia.

The idea that synaesthetes are more likely to experience IMLM than non-synaesthetes.

The (implied) idea that the method of loci memory technique is similar to or a type of synaesthesia.

The idea that synaesthetes might have a natural advantage in using the method of loci because the method of loci is similar to or is a type of  synaesthesia. This idea that seems likely in light of the case of “S” the Russian memory performer with many types of synaesthesia described by Luria. 

The idea that IMLM is a phenomenon that is caused by enhanced synaptic plasticity throughout the life span.

The idea that IMLM is a phenomenon that is caused by enhanced synaptic plasticity throughout the life span and can thus be used as an indicator of which synaesthetes are synaesthetes due to enhanced synaptic plasticity throughout the life span rather than other possible causes of synaesthesia. Support for this idea comes from the fact that IMLM appears to be a non-developmental variety of synaesthesia that can form new long-term associations in adolescence and adulthood.

The idea that IMLM is a phenomenon that is caused by the unusual possession of levels of synaptic plasticity typical of a young child, during adolescence or adulthood.

The idea that IMLM is caused or enhanced by some characteristic of the immune system that affects the functioning of the brain. Many different elements of the incredibly complex immune system are thought to affect the functioning or development of the brain, and could thus be involved in IMLM, including the complement system, microglia and the MHC class I molecules. Researchers such as Beth Stevens and Carla Shatz have investigated this exciting area of neuroscience. In 2012 I hypothesized at this blog that synaesthesia could be caused by low levels of complement, this idea implying that the immune system is directly involved in synaesthesia (or at least some cases of synaesthesia). I believe these ideas were plagiarized in a paper published in 2013.

The idea that IMLM is similar to the “Proust phenomenon” in that it is very similar to synaesthesia or is a type of synaesthesia and involves episodic or autobiographical memory as a concurrent.

The idea that phonics as a foundational reading skill is similar to or is arguably a type of synaesthesia in that it involves the involuntary association of individual speech sounds with individual printed letters or combinations of letters, as the result of learning in early to mid childhood.

The idea that at least one type of dyslexia is like a deficiency of synaesthesia.

The implied idea that if synaesthesia has as it’s basis hyperconnectivity in the white matter of the brain, dyslexia as an opposite of synaesthesia or a deficiency of synaesthesia is or could be caused by hypoconnectivity in the white matter of the brain (I suspect there might be existing research evidence that supports this idea).

The implied idea that in at least one cluster or grouping of cases synaesthesia is associated with superiority in literacy or reading skill.

The idea that synaesthesia can happen in different regions of the brain, and because of this the experience of various types of synaesthesia can vary in detectable ways because of the influence on the synaesthesia of the varied ways that different areas of the brain operate. This can mean that one synaesthete can experience different types of synaesthesia that operate in very different ways, for example, some types of synaesthesia more rare or spontaneous or intrusive than other types. (I am not completely sure of the originality or the novelty of all of this idea.)

The idea that there is an association between synaesthesia and super-recognition that is not merely coincidental.

The idea that synaesthesia is a type of memory or learning. (Not sure if I’m the first to note this obvious fact).

The idea that synaesthesia concurrents are re-experienced memories, or re-activated “learnings” of concepts, not perceptions. (Not sure if I’m the first to note this obvious fact). In support of this idea I can assert that synaesthesia is like face recognition in that both are visual memory-based phenomena which are subject to the Verbal Overshadowing Effect or something very similar. My assertion that synaesthesia is subject to the verbal overshadowing effect is based on my own observations (outlined elsewhere in this post).

The idea that super-recognizers should or could be trained and employed as expert consultants in the practice of medical genetics.

The idea that medical geneticists and all types of medical specialists need to have a super-recognizer level of face memory or face recognition ability, so that they can intuitively and quickly recognize medical facies.

The idea that there is no clear point of distinction between medical facies or faces associated with genetic syndromes and normal faces.

The idea that super-recognizers could be used to facially identify blood relatives of a person or persons.

The idea that super-recognizers could be used to facially identify the specific ethnicity of a person.

(below ideas added January 28th 2014)

The idea that super-recognition or being a super-recognizer could develop as the result of an unusual level of fascination with the visual appearance of landscapes or scenes, rather than from a fascination with faces, and thus be a side-effect hyper-development of a part of the brain that serves two similar functions.

The idea that super-recognition or being a super-recognizer could, at least  in some cases, develop as the result of a general hyper-development of the visual sense to compensate for problems in the auditory sense during childhood such as temporary deafness, recurrent ear infections, glue ear or poor auditory processing.

(below idea added February 1st 2014)

The idea that lexical-gustatory synaesthesia is an exaggerated form of some kind of evolutionary adaptation in the brain that biologically primes the mind to attend to or react to speech on the subject of food (this idea was discussed at this blog in a post dated January 27th 2011, with more consideration in a later post).

(below ideas added February 6th 2014)

The idea that creativity might be immediately enhanced during and only during the duration of physical or visual-spatial activity because the activity activates areas of the brain associated with movement and in turn these areas activate other areas of the brain including those that give rise to conceptual thinking, and the increased activation makes novel associations between diverse thoughts and concepts more likely, and that this process is like synaesthesia or is a type of synaesthesia, and the types of physical activity that are the most effective inducers of this effect might be highly specific, highly specific in effects, highly varied between individuals and highly idiosyncratic, as is typical of synaesthesia inducers and concurrents. Driving a car can act as an inducer of this effect. (I have gone some way to exploring this idea in past posts.)

The idea that mental flexibility might be immediately enhanced by the above effect, which I will name “movement – thought-flexibility synaesthesia”.

The idea that thinking might be immediately enhanced by the above effect.

The idea that memory might be immediately enhanced by the above effect.

The idea that the above effect is similar to embodied cognition or is a type of embodied cognition.

(below ideas added February 14th  and  February 20th 2014)

The idea that synaesthesia is like the process of face recognition (and vice versa), because they both

– are subject to the verbal overshadowing effect or something similar

– are automatic

– are involuntary

– have a sensory inducer, in face recognition always visual, in synaesthesia I think most frequently visual

– have or can have a concurrent that could be described as a memory, a concept or a personality (I’m comparing face recognition with personification synaesthesias and the synaesthesias that I have described at this blog which have visual memories of scenes as concurrents)

– are or can be visual in both the inducer and concurrent

– typically involve the fusiform gyrus

– involve set pairings of inducers and concurrents (same person’s face seen before then recognized later)

– involve set parings of highly specific inducers and concurrents (I recognize that an employee at my local supermarket has a sister who has just started working there too, as their faces and bodies and hair are near-identical, but for the extra acne and the more receding chin of the new employee. They are very similar in appearance but my discrimination is highly specific, just as I can recognize that the green wall on the lower floor of a public library is close to but not quite the same colour as Tuesday.)

– both can have, but do not always have an actual face as an inducer (we can recognize the faces of celebrities in photos, caricatures and art, even seeing Marilyn Monroe’s face in a pattern of brown coffee cups stuck to the wall at the coffee shop at the art gallery.)

(below idea added February 17th 2014)

“My particular interest in personification is my own theory that personification synaesthesia (as experienced by myself) or something like it gives rise to superiority in face memory (or being a super-recognizer) by naturally making the faces of unknown people more memorable and interesting”

The above is a quote from an article that was published at the blog in October 2013.

(below ideas added February 19th 2014)

The idea that the synaesthesia brain is the result of the developmental influence or shaping from, or the adaptation to, the behavioural phenomenon of “flow” as described by Mihaly Csikszentmihalyi.

The idea that synaesthesia, intellectual giftedness or high IQ and autism or Asperger syndrome seem to coincide more often than chance because gifted and autistic kids are more likely to experience “flow” and this in turn can influence the developing brain in a way that gives rise to synaesthesia.

(below ideas added February 20th 2014)

The idea that the genuine conscious awareness of synaesthesia is a threshold phenomenon that operates in conflict or competition with conscious thinking, meaning that consciously thinking about synaesthesia can inferfere with the perception of concurrents, and synaesthesia must reach a particular level of intensity before it interrupts the experience of consciousness and becomes itself the subject of conscious awareness. I think that the idea that thinking about synaesthesia can interfere with the perception of synaesthesia might be related to the “verbal overshadowing” effect which has been described and debated about by researchers. In fairness I should point out that Mark C. Price speculated in the recently published (2013) Oxford Handbook of Synesthesia that synaesthesia could be subject to the verbal overshadowing effect. My own ideas were arrived upon independently from Price’s writing or work.  I base the ideas of synaesthesia being a threshold phenomenon which can also be interfered with by conscious thinking on a number of my own observations. In direct contradiction to what I had expected to find, my scores for accuracy for individual letters and numbers in The Synesthesia Battery (a scientifically-validated online test of synaesthesia) were lower for the numbers and letters that have colours that I find beautiful and which I have thought about to some degree, while my best accuracy was for the numbers and letters that have the dull and ugly colours. It seems the less I think about the concurrents the more accurately I can percieve them when they are evoked. I have also noticed that most of the types of synaesthesia that I experience I was not consciously aware of before I started to think about and examine the idea of synaesthesia. I never realised that I had complete stability in the colours I associate with months and days of the week till I tested myself. While I had a dim awareness of colour colouring my thoughts, I’d not realised that this worked like synaesthesia till I went looking for a pattern using simple testing. My fine motor movement-visual memories of scenes synaesthesia evokes concurrents that are so fleetingly and subtly experienced that they just feel like random thoughts, and indeed I now believe it is possible that the random thoughts of many or even all people are in fact synaesthesia of various types. I have also observed that there are some very unsubtle and intrusive types of syn that I experience, and they are typically rarely experienced and are associated with people, emotions, faces, singing voices or music that I find striking or novel as inducers. Because of the circumstances of these examples of synaesthesia, I think some kind of threshold is being breached when these types of synaesthesia are experienced by me.

The idea that one of the established defining criteria for synaesthesia, that it gives rise to perceptions or concurrents which are “consistent and generic (i.e., simple rather than pictorial)”, is wrong, and specific categories of memories of complex visual images such as faces and scenes, which are processed in the fusiform gyrus, can also be experienced as genuine synaesthesia concurrents. I base this assertion on the fact that I often involuntarily experience synesthesia concurrents of this type, and I have written about such experiences right from the first post in this blog which was published in 2010. I have also named types of synesthesia that have complex visual memories as concurrents: the strange phenomenon, fine motor task – visual place memory synaesthesia, involuntary method of loci memorization, etc. There are also many accounts or scientific observations of synaesthesia with complex visual concurrents in the scientific literature on synaesthesia.

Scenes, scenes, scenes, my idle thoughts are filled with scenes

While trying to get my finger into the groove on the inner side of sticks of celery to wash them properly scenes of Leederville around the area of the Luna Cinema and the Leederville TAFE or tech or whatever they call it these days flashes into my mind automatically. There is no logical or temporal connection between celery and Leederville that I know of. This is just another example of my fine motor task – visual place memory synaesthesia. I named it myself. As far as I know I’m the first person to ever describe this type of synaesthesia in detail. I experience it all the time, and it is such an ordinary part of my life that I barely notice it. I’ve also described other types of synaesthesia that are either triggered by seeing scenes or which have visual memories of scenes as the surprising thing that is triggered by doing things such as household manual chores or thinking about particular concepts or reading or listening to a narrative story or non-fiction account that has scenes in it.

The stuff of thought is scenes and visualizations. In my opinion the front of the brain is over-rated for importance in thought compared to the back end and the under-side of the brain, which does visual processing. I believe we need to take a new LOOK at the way the brain works.

Pictures from the past

While making a cake by hand from scratch tonight, scenes from South Fremantle and Moore River flashed into my mind’s eye. While mixing the icing scenes from years ago in Subiaco appeared. I call this phenomenon “fine motor task – visual place memory synaesthesia”. As far as I know I’m the first person in the world to name it and identify it a synaesthesia. It is interesting because it violates one criterion of a quite old definition of synaesthesia, that it only involves simple sensory experiences, such as simple shapes or colours but not complex visual experiences such as objects or faces or landscapes. I also very occasionally experience the appearance of a face as a synaesthesia concurrent, which is another reason why these types of synaesthesia are interesting – because they appear to be linked to my super-recognizer ability (marked superiority in face memory). Another reason why these things are interesting from a scientific point of view is that they seem to be related to a synesthesia-like experience which appears to be the involuntary operation of an ancient memorizing technique known as the method of loci. In these experiences, which other people also report experiencing, memories of concepts become accidentally connected with visual memories of particular scenes. For example, re-visiting a spot in a carpark where I spent time years ago reading a book or listening to a talk radio broadcast will automatically bring to mind the concept or thought that I got from reading or listening there years ago. It can also operate in reverse with the concept evoking a memory of the exact scene that I looked at when I first learned about it. It’s interesting.

British former police detective and writer also a super-recognizer?

“I’ve been told I have a photographic memory. I’m not sure that such a condition exists, but it is true that I never needed to refer to my notebook in court, made interviews a nightmare for suspects and could not forget a face, crime or clue. Badge numbers, car registrations, court cases, names and faces are all stored neatly on my mind’s infinite box of index cards and I usually have little trouble recovering them when needed.”

This passage on page 12 brings to mind the famous memory genius discovered by the Russian neuro-psychologist Alexander Luria, the synaesthete newspaper reporter whose memory gift was discovered by his boss after he explained why he never needed to take notes in a notebook. Luria gave him the name of S in the book that he wrote about the case; Mind of a Mnemonist. A couple of questions also come to mind on reading the above passage. Is it true? Who can tell? The author of the passage, which is an excerpt from the beginning of the book The Crime Factory, goes by the anonymous pen-name of Officer A, so checking the truth or probability of these quite extraordinary claims would have to be difficult. Another question – if Officer A’s memory really is as amazing as claimed, did it get that way by a natural gift or by training or a combination of both? One final question – is Officer A a synaesthete like the amazing S? I’ll have to continue reading to see whether any of my questions are answered. One thing that I can say about the book is that the bit about treating a case of severe bleeding in the leg utterly contradicts what I was taught in St John Ambulance first aid classes, so I think there is at least some dodgy information in the book.

I’ve found more interesting stuff on page 53. in which the author explains the pros and cons of having a “photographic memory”, and it it clear that it can cause a condition that is perhaps related to post-traumatic stress disorder in which ordinary visual stimuli can “trigger” the involuntary retrieval of visual memories of unpleasant scenes experienced in his work as a police officer. An example given is the sight of a stainless steel draining board triggering a visual memory of a dead baby after a post-mortem examination. I think I’ve written on the subject of PTSD before when reviewing the book The Shaking Woman by synesthete novelist Siri Hustvedt, and I recall that I speculated that PTSD might be connected to PTSD. After reading this book I’m all the more convinced, because the involuntary recall of traumatic visual memories described by the policeman seems to operate in the same way as synaesthesia, and is in many ways similar to my many experiences of having non-traumatic visual memories of scenes or faces evoked by visual or other cognitive triggers, which I have argued are a less-known types of synaesthesia. I’m not the least surprised that an extraordinary visual memory can have great advantages and disadvantages.

Don’t let me mislead you into thinking this is a book about neuro-psychology. It is basically an action-packed autobiography of a British detective who has worked in England and also in Perth, Western Australia. Western Australian readers will no doubt be shocked by the ugly picture that the anonymous author has painted of the police in Perth.
