Green needle / Brainstorm - auditory illusion

Fascinating, as Mr. Spock used to say.
 
The words simply alternate. It banks on people also alternating their reading of the words to keep in sync with the audio.

Like I said when I read the left every time (4 times or whatever) it always seems to me to get it right. Then I restart it and read the right and 4 times in a row or whatever it says the right one.
 
The words cycle, and given the number of words and the odds, they often coincide.
Try reading the left side every single time, then the right side every single time...
I did that and I also listened with my eyes shut, it cycles and when I am looking it coincides half the time.
It’s about what it seems to say when you’re reading it. Nothing about having your eyes closed. And I disagree with your initial post at least based on my experience. Maybe you’re an exception if you can’t reproduce my experiences where I’d do words multiple times in a row.

Don't you get runs of consecutive heads or tails on coin flips?

It is a video file that plays exactly the same every time. So anyway I'd read "green needle" every single time and it seemed to say that. Then I rewatched the same video while reading "brain storm" and it seemed to say that every single time. I've never experienced it saying the opposite word to what I was reading though each time I was completely focusing on one particular word/phrase.

So what is your explanation?

Well this is what DeepSeek DeepThink said:

The "Green Needle vs. Brainstorm" phenomenon is a viral auditory illusion that demonstrates how the brain interprets ambiguous sounds based on context, expectation, and prior knowledge. Below is a detailed explanation of its mechanics, origins, and broader implications:

🎧 1. The Illusion Explained
Ambiguous Audio Clip: The audio is a low-quality recording from a Ben 10 toy meant to say "Brainstorm" (a character from the show Ben 10: Alien Force). However, the muffled, robotic sound can also be perceived as "Green Needle," "Brain Needle," or "Green Storm".

Perceptual Switching: Listeners hear different phrases depending on which word they focus on:

Reading "Green Needle" while listening typically makes the brain hear "Green Needle."

Focusing on "Brainstorm" primes the brain to hear "Brainstorm".

Control Over Perception: Many people can switch between the phrases at will by shifting their mental focus.

⚙️ 2. Scientific Mechanisms
Priming: The brain uses contextual cues (e.g., on-screen text) to "fill in" ambiguous sounds. This is a top-down process where expectations shape perception.

Acoustic Ambiguity:

"Green" and "brain" share similar sound frequencies, while "needle" overlaps acoustically with "storm" in noisy recordings.

Lower pitches favor "Brainstorm," while higher pitches emphasize "Green Needle".

Neural Processing: The brain resolves ambiguity by matching input to stored patterns (e.g., familiar words), refusing to perceive uncertainty.

🌐 3. Origins and Viral Spread
Source: The audio originated from a 2014 YouTube review of a Ben 10 toy. Despite the toy's intent to say "Brainstorm," the poor recording quality created ambiguity.

Resurgence: It went viral on TikTok in 2020/2021, echoing earlier illusions like "Yanny vs. Laurel" (2018).

💡 4. Broader Implications
Subjectivity of Reality: Like optical illusions, this highlights how perception is the brain's "best guess" rather than an objective truth. Two people can experience the same stimulus differently based on focus.

Real-World Parallels:

Media Influence: Repetitive exposure to ideas (e.g., via algorithms) can "prime" people to interpret events through specific lenses.

Placebo Effect: Demonstrates how expectation can alter sensory experiences, similar to placebo treatments in medicine.

🔍 5. Why People Hear Different Phrases
Individual factors play a key role:

Prior Knowledge: Familiarity with Ben 10 makes "Brainstorm" more likely.

Linguistic Background: Phonetic sensitivity affects syllable interpretation (e.g., "storm" vs. "needle").

Cognitive Flexibility: Some easily switch phrases; others cannot due to neural "wiring" differences.

💎 Key Takeaway
This illusion underscores that perception is constructed by the brain, not passively received. By choosing where to focus, we actively shape our reality—a concept applicable to conflicts, media literacy, and personal mindset.

The first time, without looking, I got nothing.
The second time, looking at 'brainstorm' I heard brainstorm.
The third time, looking at 'green needle' I heard green stone.
I just couldn't hear needle.
I only hear two sillables. Brainstorm is two, green needle is three.
How many sillables is needle for you?

BTW I wonder how good your auditory imagination is... can you imagine music in your head? Can you picture coloured images? I can hear music but can't even picture anything - not even a circle, etc.
 
Van Gogh heard various piano keys as producing chrome yellow or Prussian blue. Rimbaud saw colors for each vowel. Synesthesia.
 
Illuminations is one of my fave poetry collections, though for the most part I have no idea what the poems are about. A Season in Hell is more accessible.

On the topic of favourite poems I have no idea what they're about:

Wow, I'm sick of doubt
Live in the light of certain South cruel bindings
The servants have the power
Dog-men and their mean women
Pulling poor blankets over our sailors

I'm sick of dour faces staring at me from the TV tower
I want roses in my garden bower; dig?
Royal babies, rubies must now replace aborted strangers in the mud
These mutants, blood-meal for the plant that's plowed

They are waiting to take us into the severed garden
Do you know how pale and wanton thrillful comes death on a strange hour?
Unannounced, unplanned for like a scaring over-friendly guest you've brought to bed
Death makes angels of us all and gives us wings where we had shoulders
Smooth as raven's claws

No more money, no more fancy dress
This other kingdom seems by far the best
Until its other jaw reveals incest
And lose obedience to a vegetable law
I will not go
Prefer a feast of friends to the giant family
