Musings, news, and research about neurology, brain physiology, psychology, and behavior. Particular focus on Autism, ADHD, and depression.
Where does this technique reside within this one spider? Where does it reside within the species?
What triggers the processing of this knowledge?
How does the spider understand (or at least experience) the need and the solution?
How does the spider brain process this knowledge without a sort of visualizing?
If spiders can visualize physics concepts
and the parts they’ll need… and collect them…
and assemble them properly…
How should we visualize the minds of spiders?
A dye that glows brighter in the presence of calcium ions is loaded into the neurons. Neurotransmitters released by an upstream neuron in a network lead to rapid calcium influx in downstream neurons, seen here as a sudden burst of green. The influx triggers an electrochemical propagation of a signal down the length of the neuron, called the axon, and causes the subsequent release of more neurotransmitters, which signals the next neurons in the same network to fire.
Winners interpret good luck as merit-based, even when the rules overtly favor them and no skill is involved.
When I notice evidence-based research relating to my articles I am adding them.
“At the end of their game, people were asked if it had been fair. Regardless of the conditions, winners were more likely to say yes than losers. Even when the winners benefited from receiving either one or two strong cards from their opponent, they were twice as likely to judge it a fair game as the losers. What’s more, in most versions of the game winners were more likely than losers to attribute success in the game to talent – even though the game required very little.”
Growing disparities of income and wealth have prompted extensive survey research to measure the effects on public beliefs about the causes and fairness of economic inequality. However, observational data confound responses to unequal outcomes with highly correlated inequality of opportunity. This study uses a novel experiment to disentangle the effects of unequal outcomes and unequal opportunities on cognitive, normative, and affective responses. Participants were randomly assigned to positions with unequal opportunities for success. Results showed that both winners and losers were less likely to view the outcomes as fair or attributable to skill as the level of redistribution increased, but this effect of redistribution was stronger for winners. Moreover, winners were generally more likely to believe that the game was fair, even when the playing field was most heavily tilted in their favor. In short, it’s not just how the game is played, it’s also whether you win or lose.
- He has Parkinson’s
- She has epilepsy
- He’s schizophrenic
- She’s autistic
No, it’s not the setup for this years wackiest RomCom.
It seems one might possess Parkinson’s like a teacup chihuahua or a classic mustang whereas autism is who you are. You could make the case that autism or schizophrenia dramatically shape your personality in a way that defines you, while the other two do not…but you’d be wrong. The communities of caregivers surrounding them commonly describe what they know as the Parkinsonian and epileptic personalities. What decides this automatic and unnoticed distinction between Being a disorder and Having a disorder?
How can you be a diagnosis? The taxonomy of neurological types used to label people aren’t real things that people can “be”. They are checklists where we matched the diagnostic criteria enough to call the result positive. “Enough” might be 4 out 7 matches, for example. Diagnostic criteria are simply a collection of behaviors and bio-metrics accepted by the medical community. It’s rather like asking hunters (the hunting community?) the 7 most distinct characteristics of deer. That might be kind of fun but the heuristic is: “I know one when I see one”.
Different neurologies are utterly real but neurological types are descriptions, the names for vertices of behavioral parabolas distinct enough to contrast sharply against normal. Normal is the smooth melted butter river of behaviors we mostly can’t even notice because of how overwhelmingly common they are. Normal isn’t a thing either, it is a thing that’s going on. Normal is a strange state, only seen clearly when it is held next to things that are not… a bit like a black light held over a motel bed. Normal isn’t a cool matter-of-fact background to things. Normal is the thing we fear when we make a terrible impression, Normal is the cop we all feel oddly guilty in front of. Normal is being home or cast out in exile. In meat-and-potatoes reality, there is no break from normality that calls for a celebration.
Throughout human existence Normal functioned as an immorality finder. Where immorality was uncovered, normal was declared missing…even for commonplace behaviors that simply got on the wrong side of something socially cherished. The other side of Normal’s coin is perversion of course. So Normal is tainted and muddled by being a measuring device cum moral cudgel. If you trace it back far enough you’ll find Normal describing primate pro-social behaviors that maximize pregnancies and group survival.
There is a rather famous story about moths that you might well have encountered as a student. The class would have been discussing evolutionary theory.
The common form of peppered moth had a pale coloration suited to hiding on the bark of light-colored tree trunks. This camouflage apparently enabled it to avoid being eaten by birds. Then, in 1848 a specimen with black wings turned up, in the industrial city of Manchester, England. By the end of the 19th century, the dark peppered moth was everywhere, and the paler, mottled version had vanished, becoming virtually extinct.
This was perhaps the first clear instance of human behavior increasing environmental pressure on local species and observers noting and following it. The industrial revolution roared up to speed and the universal use of coal for heating and industrial production had blackened skies and forests. An editorial in an issue of Nature quotes an 1851 railroad guide to the English industrial midlands: “The pleasant green of pastures is almost unknown, the streams, in which no fishes swim, are black and unwholesome…the few trees are stunted and blasted.” Continue reading
“Unmotivated seeing of connections” accompanied by a “specific experience of an abnormal meaningfulness”. — Klaus Conrad
3 aspects of Apophenia
- Confirmation bias – From a background of randomly distributed items; associating items that have no connection except that they fit the story you are already telling yourself.
- Rejection bias – Ignoring or denying information that DOESN’T fit the story you are telling yourself.
- Pareidolia – (less important, but related) A sensory stimulus which is interpreted by the mind as something else. For example being in the shower and the sound of the running water is interpreted as possibly your phone ringing. Or the faces seen in teapots, trucks and clouds. Or Jesus on a piece of toast.
In a few other articles I’ve made the point that random millions of people having babies with other random millions of people give birth to consistent percentages of neurological and psychological types relative to the population at large, generation after generation. Some of these groups are defined as disabilities or pathologies. Example groups ADHD, and ASD are disabilities, sociopaths are seen as pathologies…it’s the second part of the name! They are generally thought to be caused by failures of infant development to complete normally and a pretty strong genetic connection. ASD is the obvious example of a spectrum disorder. Predictable numbers of ASD people are born year after year.
Clinically ASD includes a short list of recognized levels of the disability which exist along a continuum of severity. There’s a break here between the small range of what’s accepted as proven medical science to be autism and the much broader range of people who are legitimately diagnosed as autistic even though they are much higher functioning than the accepted range. It’s tacitly understood by therapists, teachers, parents, etc to be a section of spectrum that could be positioned at the end of the current spectrum and just pick up where it leaves off and run all the way out to those who have a few touches of these traits but are otherwise completely normal. That makes sense as the autism spectrum. I’m grandfathering ADHD in on this spectrum because 80% of high functioning autistics also have ADHD. Continue reading
