Instincts are learned not earned

Instincts are something that only works if you are exposed to that particular event more often? Why did your instincts never said that you are going to die or the world is gonna destroy? Instead it tells you that there is gonna be a fight or riot or you should not go out now (kind of things)? What do you think about this?

Feel free to explain how critters do complicated behaviors without learning them.

Example: third generation butterflies that migrate to Mexico from North America?

Actually i don’t know about the butterflies. But i will explain about humans instincts - instincts are about material world objects ( im pretty sure our dna has no information about the material world objects)… So as we interact with the reality more often we learns to make instincts. Fear of snake info is not stored in our dna instead we learned and also its not fear about the snake but its fear about the death. But this fear on death was hidden by the fear of snake thoughts.

You seem to be confused about what an instinct might be.

Left me share an example I have had experience with: the nesting instinct.

Before I ever learned what it was I observed it in my wife. When my first son was due my wife had a sudden burst of energy in paint the room we had decided was to be the nursery. Normally she has me do work like that but I did not think much of it. When I saw her on her knees cleaning the oven ( totally uncharacteristic behavior for her) I knew something strange was going on.

My son was born the next day.

For each of the next five children she has had these uncharacteristic bursts of nesting activity. When I asked her why she was doing these things she reported that she just felt like doing them.

It’s not the specific motor programs but the types of activity.

" Any behaviour is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning, and is therefore an expression of innate biological factors."

There are many archetypes built into the subcortex that are built in. One member of my study group recently reported an encounter with a snake where he found himself jumping backwards before he was even aware of what it was he was seeing. It was only after he had jumped back that the snake registered in his consciousness. This is not surprising as the cortex processes at roughly a 10 Hz rate - the subcortex is much faster.

What is he assumed that?

There are numerous shapes that are built into the amygdala, some we like, some we don’t.
Faces are well known and don’t drive fear.

Does the next 5 children born the next day? Or in any short time

What if seeing faces kills us?

This assumption that 'some we like, some we don’t like ’ is kind of seems we solved a problem for the sake of finishing not for sake of problem.

In the long run, evolution is very good at tuning the shapes. I don’t know how the are stored but I assume the program works something like how critters have color patterns - say - like tiger stripes.

Actually it might be, see:

Pulvinar neurons reveal neurobiological evidence of past selection for rapid detection of snakes

The present study shows preferential activity of neurons in the medial and dorsolateral pulvinar to images of snakes. Pulvinar neurons responded faster and stronger to snake stimuli than to monkey faces, monkey hands, and geometric shapes, and were sensitive to unmodified and low-pass filtered images but not to high-pass filtered images. These results identify a neurobiological substrate for rapid detection of threatening visual stimuli in primates. Our findings are unique in providing neuroscientific evidence in support of the Snake Detection Theory, which posits that the threat of snakes strongly influenced the evolution of the primate brain. This finding may have great impact on our understanding of the evolution of primates.



Dr. Cisek describes how evolution added function to the brain through addition and/or replication. Much is retained but often repurposed.

It is not difficult to see that “lower” animals are capable in managing interaction with other life forms. Much of these behaviors are instinctive and surprising sophisticated. This is the subcortex that is retained as the controller of the cortex - the default operating system. We have instinct but they are so universal that we have no version of mammals without them; they are kind of invisible. We just want to do stuff and nobody knows why.

Avoiding, approaching, and using affordance plays significantly as building blocks in subcortical programmed behavior.

The cortex shapes these to be more fine, flexible, sequentially chained, and particularly, executing fine grained goals.

Interesting… To read

Is fear a assumption about things? Eg. I mean we fear of snakes that doesn’t kill us, you know non-poisonous snake. Can we conclude that everything we do and believe is based on assumption from experience?

Color patterns are encoded in dna, bcoz these colour code cells are needed to produced inside the body. But neurons are all the same with same functionality how do they do different actions?

A more accurate description could be: certain neural connection patterns are encoded in DNA. Those neural patterns (or circuits) detect color patterns.

A pile of neurons don’t function. A network of circuits (either built with vacuum bulbs, or semiconductors, or neurons) can perform different actions, demonstrate intelligent behavior.

A similar question might shed some light – Is Patellar reflex an assumption about things? The obvious (or not so obvious) answer is, No. It’s just a reflex, not even through the brain.

Then why should ALL instincts be assumptions about things? Maybe not.

You were right, the same functionality i mean is passing action potential. Can we propose a brain with many functionality(like dreaming,thinking,muscle movement) with just one principles as ‘passing action potential’?

Reflex doesn’t have to recognized by body but snakes have to be recognized. Eg, our eyes close when objects strikes our face faster (this is also a form of reflex) you can’t control reflex but you can control your fear about snakes (think about humans living snakes)… Things that were should be recognized to induce fear in our mind is self-created one (a assumption).
