Can phones read minds? – Cool Magic Tricks With Cards For Kids


A Stanford expert says the answer could be “yes”.

The answer comes in cases where the brain is operating like a computer and a phone can detect what you’re thinking.

For the study, it involved a group of healthy college students who were instructed to imagine a voice with different intonations in their head.

When told their brain had been recorded, students responded most reliably to the original voice, which was in the low-frequency range.

They then thought about the voice they had dreamed about.

However, if they played a voice with a higher-frequency sound, called high-frequency noise, then they had trouble recognising the original voice.

That suggests that our brains don’t have the brain activity to recognize high-frequency voices because they are too far away from the ears.

They also have trouble thinking of those voices themselves unless you are able to see them – which is hard enough to do with a phone.

The findings were published in the Proceedings of the National Academy of Sciences (PNAS).

“It looks like the difference in brain activity is related to what is in the distance that we can’t hear but the phone can,” Stanford University’s Jonathan Mayer said.

But he warned it was too early to say with certainty that high-frequency noises were influencing some people’s abilities.

He said that, in general, the brain’s visual processing centres had a stronger impact than those working in the auditory processing centres.

“What’s exciting is that different brain areas are associated with different abilities,” he told BBC News.

“There is definitely this suggestion that [the ability is] influenced by the brain’s capacity to interpret sounds as coming from a higher pitch.”

The
idea of “listening to the voice that you’ve dreamed of” has been around since the mid-19th Century and was put forward by a Swiss psychiatrist who first coined the term.

There have been several theories about what causes it, but all suggest that it relies on the interaction between three areas of the brain: the auditory area and the posterior cingulate cortex, which are linked to vision, and the temporal poles, including
