More of my amazing ideas! Beware!

In the past at this blog I’ve shared a large collection of ideas in the areas of neuroscience and psychology that I’ve managed to think up all by myself, independently but often with inspiration from my own experiences, situations that I’ve observed or my reading of science magazines or scientific literature, or a combination of the above. I’ve not exhaustively searched to see if I was the first person ever to publish all of these ideas, but I’m sure that some of them at least were first published by me at this blog.

I’d now below like to add to my collection of ideas, but this time not limiting myself to the subject areas of this blog. Please note that this page and all pages at this blog are permanently archived, and if you choose to copy my words or plagiarize any of my ideas, if I was the first to publish that idea or ideas, I will find out and I will make you sorry. Very sorry. 

So, here’s some ideas, some serious, some not so:

Chocolate goods producers and major supermarkets can prevent groups of racist redneck lunatics from accusing them of pandering to non-Christian minorities by failing to label traditional Easter and Christmas goods explicitly as Easter and Christmas goods, by bringing out a range of colourful foil-wrapped chocolate Jesus figures and delicious Flake-bar crucifixes, maybe even entire chocolate nativity scenes and twelve apostles sets, all clearly labelled “Easter” and Christmas”.

As a form of living sculpture or sensory play activity for children, grow one of those mulberry trees that has an abundance of black fruit and grows very large, and underneath the canopy cover the ground in white-coloured quartz rocks that have been tumbled a bit to wear off the sharp edges, prevented from sinking into the dirt with white weedmat or some kind of durable pale-coloured matting that will allow for drainage. In the spring the ground should become a purply, pinky fruity-smelling mess, a celebration of the staining power of mulberries.

Are prosopagnosics over-represented among scientists, science graduates or among popularizers of science? If so, is this because they develop a skepticism about unconscious, intuitive ways of thinking that give instant insights, as a natural consequence of experiencing this type of thinking less often that other people do? Is this a motivation to seek and understand and advocate for the more deliberate, conscious and explicit ways of thinking and reasoning that make up the methods, processes and statistical techniques of science?

Is the Availability Heuristic partly to blame for common and inaccurate ideas about the nature and numbers of refugees coming to Australia, when news TV shows constantly depict refugees as crowds arriving on boats rather than modest numbers of people (relative to foreigners arriving with working visas) arriving by plane? I believe there is evidence that the visual depiction of information is more influential than written or abstract information, and news TV may be unwittingly generating misleading beliefs about refugees when they choose exciting and distinctive visuals of swarms of exotic people on crowded boats to make their news stories about refugees more attention-grabbing.

Is the Trolley Problem thought experiment relevant to the phenomenon of parents refusing to vaccinate their children? The Trolley Problem shows us that a minority of people express irrational reluctance to take an action that will kill a person in order to save the lives of a greater number of people. Obvious parallels can be pointed out between this situation and that of a parent who fears some aspect of vaccinations refusing to “harm” their child regardless of the benefits.

Can the normal mean score in a test be double-checked after it has been used in published studies by gathering up all of the data of the scores of control group or normal study participants who have been given the test, in a systematic search of the literature, and then pool this data and calculate an average score?

Sad but not surprising that prosopagnosics can be mistakenly perceived as having a personality issue rather than a perception issue.

I’ve got an anecdote that is rather like the opposite of the one shared by Dr Karl in the radio show, in which he came to understand that he had an unusual problem in recognizing fellow-students at university. Just this week I recognized (with no foreknowledge) a student that I once shared a tutorial group with when the student made a very brief appearance as an actor in a television advertisement. Nice! I wish him the best of luck in his acting career. He was working in a series of health promotion ads that consistently feature better acting than that often seen on the TV shows.

In case you are wondering, the music used in the radio show were two hits of the 70’s; that famous tune by Grace Jones and at the end the big hit by Roberta Flack.

The search for an effective intervention for prosopagnosia continues, but at least the knowledge of what is going on must be some help to people who face this challenge.

Story on super-recognizers on Australian radio with link to test

This story with an interview of Australian researcher Dr David White was broadcast last year. I’m not actively trawling for items about super-recognition to post about here, so I only just came across it by chance.

Readers of this blog might be interested in the download linked to from the RN web page for the story, which is a difficult face matching test. I’ll give you a tip and advise to only look at the faces as you go and record your own answers as you go, and check them later.  I got only five out of eight correct.

Why you will leave shops empty-handed this Christmas season, just the same as last year, and the year before that….

As sure as night follows day, in the days leading up to Christmas supermarkets will run out of packets of dehydrated French onion soup, just when you had the idea to make your own cheap but tasty party dips out of cream cheese or sour cream and the aforementioned processed soup. I’m guessing this happens every year because the state-of-the-art stock ordering computer programs used by the supermarkets group products into categories, and soup being a product range that generally sells more in winter, is not ordered in any quantity in the summer season leading up to Christmas in Australia. Perhaps a similar logic explains why breakfast foods such as hash browns and kippers become scarce in the festive season. I’m guessing that cooked breakfast foods aren’t items in the summer range, even though big cooked breakfasts have been a popular form of family Christmas meal in Australia since the 1990s.

More common and perennial problems in stock replenishment in retail establishments are the big empty chasms where useful and desirable products are supposed to be stocked, and the related problem of the wrong product housed in slots on variety and supermarket shelves. These issues are a problem for retailers, as in the former situation a sale does not happen and in the latter situation the item stocked will most likely be advertised at the wrong price. If the shopper has seen a box of 375g salted mixed nuts stocked in a slot displaying a price of $3.00, around $3.05 less than the price that it scans at, the customer has every right to insist that they be sold the item at the lesser price that they saw when they selected the item, even though I’ve found that staff at a local Woolworths supermarket will defend their right to display $8 pots of bubble-mix in the slot in the toy section designated to $3 bubble mix, not conceding one red cent of discount, whatever the consumer law might say. Shoppers also have a problem when stuff isn’t kept in the shops where stuff is meant to be found. When confronted with fresh air where an item on their shopping list should be found a shopper could feel peeved, because they then have to walk across the shopping centre or drive across town to source an alternative, or do without. And when they are confronted with incorrectly shelved items they may become misled or confused over the price. And the problem goes deeper than that. When some dunce fills a box of Fimo soft light modelling clay packets into a slot at an Officeworks store which was supposed to house similar-sized packages of Das air-drying modelling clay, and hangs an “out-of-stock” sign where the Fimo item should reside, the Fimo is then advertised at the wrong price as a different product, and I’m guessing when the automatic stock-ordering system delivers more of the Das clay, which is really out-of-stock, the shelf-stocking person might find an full slot where their box of Das product should be placed. What happens next is anyone’s guess, but I know that in supermarket night-fill operations the workers are placed under constant pressure to throw product onto the shelves fast, so there isn’t time for anyone to pull the twenty-three blackcurrant jam jars out of the blackberry jam slot, rebox or rehouse them all, and then refill the slot with the contents of the box of blackberry jam. What will probably happen is that the box of blackberry jam will be marked as overstock and returned to the back of the supermarket on a cage to languish in darkness for an indefinite sentence. I hope you like blackcurrant jam, and I hope you don’t have an allergic reaction to the hazelnut wafers that were shelved in the chocolate wafers slot.

I understand that once retail shelves have been allowed to degrade into a state of chaos the disorder becomes a self-perpetuating system, and I know that hope can never be held for any logic or order in any retail space devoted to an extensive range of light globes, but I also wonder whether I’m the only one who sees the errors in product stocking every time I walk into a shop or walk down a retail aisle. Do other shoppers notice the boxes of fish fingers heaped six-high above the fill-line in the freezers? Do store managers notice the expired use-by dates, the 600ml bottles sitting in the 300ml bottle slot, the grey bacon, or does it not register? If they do see the mess and the mistakes, does it not bother them?

The phrase “an eye for detail” pops up fairly frequently in the world of recruiting and HR but no one ever tests for it, and as far as I know, there are no valid, reliable, standardised tests relevant to “eye for detail” and I know of no scientific definition of this ability (readers please correct me and inform me if you know more about this than I do). The standard of spelling ability of job applicants might be used to estimate “eye for detail”, but this standard is a fairly low bar, and it is also not an area of ability that another poor speller is able to judge. One fundamental truth that I’ve learned in researching the science of face memory and visual recognition is that seeing doesn’t simply happen in the eyes, it happens in the eyes and brain. You can have your eyes open but not really see if your brain isn’t processing the information supplied by your eyes, and that is why we all get to see so many dark, empty spaces when we are trying to stock up for the silly season.

Don’t confuse poor face memory with aphasia

I know this fascinating article is from 2013, but it makes such an important point about face recognition that I want to bring it to your attention, if you weren’t already aware of it. The ability to remember a person’s face is a different ability than the ability to name the person the face belongs to. These abilities are evidently processed in different areas of the brain. Unfortunately, there is no direct link to the journal paper this article summarizes, so I cannot quickly determine whether the test using the faces of famous people is the same as the “Famous Faces” test that I have previously mentioned at this blog (and done myself). It does sound similar to one of the tests offered here, free of charge: https://www.testmybrain.org/

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.
