2/3. Hyperphantasics actually have a similarly difficult time with these techniques as aphantasics - but in a different way. While aphantasics struggle to visualize, hyperphantasics struggle to control their intense visualizations for therapeutic purposes.

3/3. Combined, our studies suggest that both extremes of imagery respond unpredictably to therapeutic mental imagery techniques and experience mental health symptoms differently from typical. Therefore, both need more attention in mental health research!

1/3. We thought that because having mental imagery seems to help with common therapeutic techniques like guided imagery or imagery restructuring, perhaps having hyperphantasia helps you to be especially receptive to these techniques. But this is NOT what we found!

Humans are not black boxes. Experience is everything. This is not a definition problem. This is a "completely ignoring human experience" problem. Some things cannot be measured objectively (yet). Until then, qualitative evidence is the most important evidence we have.

Y: "For sleeping you count sheep. The problem was...I'd imagine sheep jumping over, but then my thoughts would run away with this and I would...have things pop in...there might be a wolf...or there might be goats...and it would be a problem with me controlling these things."

W: "I would say my consciousness is much less...less connected to my body...than a lot of people... so when I talk about, oh you know, what if you could be a cyborg, I’m like, hell yeah, sign me up, because like, to me, what’s going on in my head is like so much more interesting."

T: P3 created a mental box to house traumatic and anxious imagery. She had trepidation about the images coming back if she were to engage with them: “I wouldn’t want to use [the boxes] again because then it would remind me, and I’d visualise what I went through if I was to think about that box."

U: "What it is like for me, reading books... I create all the places described, and I can like, it’s like I see it all, and then looking back, even books I’ve read, oh, years ago- I can like see these places like kind of a memory."

R: "As a child I had such vivid- they weren’t even night terrors...they were imaginings. And I used to pretend that they were nightmares because I knew that you were allowed to get distressed by a nightmare, but if you were awake and seeing horrible things, then it was naughty to...make a fuss."

S: P6 found mental images too realistic, and so could not tolerate interacting with them: "I think if I spoke to the Gothic horrors, then, then they might (laughs), think they might slip across and become real. I know that they wouldn’t, but that would be a really bad idea."

P: "Both me and my daughter can’t cope with reading fiction...It’s always too intense. Always. The feelings, the emotions...it’s so intense, and it’s more intense in a book than watching a film...at least with the film, it’s someone else’s, and I can switch it off."

N: Several participants had well-established inner worlds that they could step into and control at whim. P5 steps into a dystopian world, where it is just him and his dog. “It’s been like therapy for me in some ways. Because it's the one place that I’m safe...because I genuinely control everything."

O: On having a fantasy world in their head: "There’s no responsibility at all in that world. There’s no pressure from anybody else because nobody else...no expectation...it really does...have an emotional effect on me."

K: All participants expressed having an inner world with no limits to it. "It’s just literally being able to do anything... I would like to say, limitless in some ways." L: "it’s kind of constantly fun ... you never need to get bored because you can ... do anything."

M: "To be able to be so vividly imaginative and...actually go off into that world...I’m quite poor. My world is very small. I live alone. My children have grown up and they live far away...But...I don’t lack for company (chuckles) because...I can have it all going on, within me."

I: "This would leave participants weary of thinking about the past because “if I go too deep ... they become really distressing because I’m right back... I know exactly how that situation was on every sensory level, and so I ... keep things at arm’s length."

G: "People with really vivid imagination keep reliving things, keep remembering and seeing them." All participants reported slipping into memories against their will and being overwhelmed by them as though experiencing flashbacks.

H: "I've always felt like (said slowly) like part of the reason I struggle with difficult situations is because of, (pause) the- the video, like realistic, constant playing out in my head of events and times and this sort of never ever being able to forget because it’s always very, very real."

E: "I find myself just distressed a lot, and a lot of the distress is not being able to switch that off, not being able to stop it being so vivid. I don't really mean switch it off, I mean, stop it being quite as vivid, because if it was just taken down a few notches, it would seem more positive."

F: "Once I've seen the thing, I cannot get it out of my mind. So, for years afterwards, I’ll be revisiting that scene ... it’s become as part of my kind of fabric of my thinking ... and it’s impossible to get rid of it."

Exhibit C: P1, P4, and P7 noted how they could picture a relaxing beach scene which is often used in guided imagery, but that the imagery detracted from the relaxation, and was "unhelpful ... because it’s so real."

D: "I don’t like the intrusive stuff, like...a spider (disgusted expression)...I can see it. I can feel it. I can (shaking head)...it’s too much and it’s always negative stuff. That’s [the] part I don’t like (head shake)–because my imagination is so vivid, it just-it goes beyond- goes too far."

Exhibit A: "It’s in here (pointing to head). Which is why it sounds wrong to say I can see it, (quote gesture with fingers) but ... the thing in my head (tapping head) is the same as the thing out there."

The business model of higher education is real, and it's depressing for academics who have a love for knowledge and see the greedy leaders at the top who just see the bottom line. Students and staff suffer under this model. If you think it's all fine, you've got your head in the sand.

So @mmonzel.bsky.social read my bsky thread and proposed we extend these ideas into a theory paper - and thus, this preprint was born! A unifying theory of aphantasia: Aphantasia as the inability to disengage from the external environment osf.io/preprints/ps...

With this new pub arguing that aphantasia is NOT an episodic memory condition, I agree that aphantasia must be defined, first and foremost, by a lack of imagery. However, aphantasia reduces the vividness of episodic memories in predictable ways. Here's another idea... 1/8 rdcu.be/eYxns

From the article: "The ability to conjure mental imagery is a key aspect of being human." This is amusing, because I literally have a paper under review titled "mental imagery is not essential to being human" 🤣
