Abstract: A brand new research reveals that aphantasics, individuals unable to visualise, are extra immune to involuntary visible ideas, comparable to imagining a pink elephant. Whereas vivid visible imaginations usually result in intrusive imagery, aphantasics appear to redirect their ideas to different psychological processes, like summary concepts or auditory daydreaming.
This implies that aphantasia is a part of the pure range of human minds, with strengths like decreased susceptibility to intrusive imagery balancing the lack to visualise. These findings problem the belief that psychological imagery is common and spotlight the distinctive methods completely different minds navigate ideas.
Key Info
- Aphantasia Outlined: Aphantasics can’t voluntarily visualize and are much less vulnerable to involuntary visible imagery.
- Intrusive Ideas: Folks with vivid visible imaginations usually tend to expertise intrusive imagery.
- Cognitive Range: Aphantasia provides strengths like decreased visible intrusions however several types of daydreaming.

“Inform a person he shouldn’t consider a pink elephant and he can’t get that beast out of his thoughts!”
This quote, from Curt Siodmak’s 1974 novel Metropolis within the Sky, describes how onerous it may be to suppress our ideas. “Don’t consider a pink elephant” has turn out to be a basic instance of how troublesome it may be to deliberately keep away from visualising.
Analysis suggests a lot of you, having examine a pink elephant, can have imagined seeing one.
Nonetheless, some individuals, like us, have aphantasia – we can’t visualise. So we’re just a little confused on the concept different individuals can think about seeing issues that aren’t there.
In a new research, we’ve got discovered proof the pink elephant downside isn’t common. Some individuals – together with individuals with aphantasia – can block involuntary visible ideas from their minds.
What’s aphantasia?
Folks with aphantasia can’t voluntarily think about seeing issues in our thoughts’s eye. So in case you ask us not to consider a pink elephant, we received’t visualise one, as a result of we are able to’t.
Aphantasia is usually described as a deficit. When individuals first be taught they’ve aphantasia they’re usually upset, as they realise different individuals can do issues they can not. It could be good to think about seeing the characters described in a guide, for instance, or to visualise an absent beloved one.
Nonetheless, deficits are sometimes balanced by advantages. There are solutions individuals with aphantasia (or aphantasics, as we’re typically known as) could have a heightened resistance to involuntary intrusive ideas.
One other approach to have a look at it’s that aphantasics are one portion of a pure range of human minds, with individuals having completely different capacities to visualise. The place aphantasics haven’t any capability, most individuals would have a median skill, and a small variety of individuals would have an especially sturdy skill to visualise.
Vivid psychological imagery and involuntary visualisations
In our new research, we checked out hyperlinks between the depth of individuals’s visible imaginations and their tendency to visualise, even after they strive to not. Folks with vivid visible imaginations have been extra prone to have involuntary visualisations, and we might predict these outcomes by measuring mind exercise.
Some individuals may take pleasure in with the ability to think about seeing detailed scenes every time they want. Nonetheless, this appears to return at the price of not with the ability to shut down these experiences.
Most individuals have much less vibrant imagery, however they appear to be extra in a position to suppress these ideas.
Do aphantasics have peaceable minds?
Aphantasics are unlikely to have involuntary visualisations. Does that imply they’ve peaceable minds?
In our research individuals who reported having weak imagery have been much less prone to think about seeing issues they have been making an attempt not to consider. Nonetheless, they have been extra prone to report mind-wandering.
If this describes aphantasics, as a substitute of visualising issues we’re instructed not to consider, we could flip our minds to different ideas, comparable to what’s for dinner. So we might not have extra peaceable minds, only a resistance to consider issues we are attempting to place out of thoughts.
If aphantasics don’t visualise, have they got daydreams?
From our personal expertise, we are able to affirm a minimum of some aphantasics have minds that wander. However when our minds wander, neither of us imagines seeing issues. Our experiences are completely different.
When Derek’s thoughts wanders he imagines listening to and interesting in purely audio conversations. As daydreaming is usually related to imaginative and prescient, he didn’t realise till very lately these imagined conversations might be described as his expertise of daydreaming.
Loren can’t visualise or think about listening to issues. She experiences her ideas as completely different sensations of texture and imagined emotions of motion – and these are what she experiences when her thoughts wanders.
Are aphantasics immune to trauma from re-living occasions?
Maybe.
Whereas our proof suggests aphantasics are immune to involuntary visualisations, extra analysis will probably be wanted to work out if we’re immune to reliving traumas, or if these will merely set off several types of imagined expertise.
What is obvious is that Siodmak was mistaken. Should you inform individuals they shouldn’t consider a pink elephant, a few of us will fortunately put that beast out of our minds, and switch our ideas to different issues. What’s for dinner?

“Don’t consider a pink elephant: Particular person variations in visualisation predict involuntary imagery and its neural correlates” by Derek Arnold et al. Cortex
Summary
Don’t consider a pink elephant: Particular person variations in visualisation predict involuntary imagery and its neural correlates
There are substantial variations within the capability of individuals to have imagined visible experiences, starting from a lifelong lack of ability (Congenital Aphantasia) to individuals who report having imagined experiences which are as vivid as truly seeing (Hyper-Phantasia).
Whereas Congenital Aphantasia has usually been framed as a cognitive deficit, it’s attainable {that a} weak or absent skill to have imagined visible sensations is balanced by a heightened resistance to intrusive ideas – that are skilled as an imagined sensation.
Right here, we report on a direct check of that proposition.
We requested individuals to both think about, or to strive not to think about having a variety of audio and visible experiences whereas we recorded their mind exercise with electroencephalography (EEG).
Rankings describing the subjective vividness of various individuals’s voluntary visualisations predicted if they’d additionally report having involuntary visualisations – comparable to an imagined expertise of seeing a pink elephant after they have been requested to not.
Each the prevalence of various individuals’s involuntary visualisations and the standard vividness of their visualisations might be predicted by neural correlates of disinhibition, working reminiscence, and neural suggestions.
Our information recommend that the propensity of individuals to have involuntary visible experiences can scale with the subjective depth of their typical experiences of visualisation.
