Blog article that I wrote in 2011 linking Tetris Effect with PTSD and synaesthesia, inspired by reading an autobiographical work by an acclaimed novelist:

As is the case with face recognition, it’s all about visual memory.

Damn, it’s behind a paywall

I was wondering whether this interesting-sounding paper might mention face memory ability, because other research has shown that ability in this area peaks much later than many other cognitive abilities, in the third decade of life, as I recall, and no one knows why, and it is one of those fascinating mysteries in psychological science that I love to ponder. It is certainly nice to know that there is even one cognitive ability that peaks as late as the seventh decade of life, considering how long it has been since I saw my 30th birthday. I also noticed that one of the authors of the paper (Laura Germine) is one who has done face memory research in the past, and some of the data used in the study was gathered using a website that has a history of offering free to the internet public access to world-class face memory and face perception tests (testmybrain.org). But the paper is behind a paywall, so I’m left wondering.

Recent paper about early visual perception and hunger relevant to lexical-gustatory synaesthesia?

I’ve not been able to access the full text of this paper, and an abstract does not appear to be available from PubMed, but science journalist Mo Costandi has summarized this paper in a tweet thus: “Hungry people see food-related words more clearly than people who’ve just eaten”. Such a psychological process has some important features in common with my lexical-gustatory synaesthesia, which I have described in a post at this blog. The phenomenon apparently observed in this paper is a cognitive bias in a very early stage of sensory perception which is involved with an interest in food. This explanation seems just as applicable to my synaesthesia in which the sound of or the thought of a limited set of non-food words and names automatically evoke the thought of foods that have names that sound simiar to the non-food words or names that trigger the experience. Like other types of synaesthesia, a particular word or name evokes the concept a particular food. Lexical gustatory synesthesia is a scientifically recognized type of synaesthesia, but it is most commonly described in the form in which the sound of words evokes actual taste sensations. My synaesthesia perhaps at times crosses the border between concept and taste sensation, but not strongly. The big difference between the phenomenon apparently observed in this paper and my lexical-gustatory synaesthesia is that one is visual while the other is evoked by concepts or sounds. I thin this is a fine example of how synesthesia is not just a neuropsychological curiousity, but can help scientists to understand the basic workings of the mind.

A type of synaesthesia which I experience in which non-food words or names automatically evoke the concepts of particular foods: is lexical-gustatory synaesthesia an evolutionary adaptation?  https://superrecognizer.wordpress.com/2011/01/27/a-type-of-synaesthesia-which-i-experience-in-which-words-or-names-automatically-evoke-the-concepts-of-particular-foods/
