Why are we so attached to things?

After witnessing the violent rage shown by babies whenever deprived of an item they considered their own, Jean Piaget, a founding father of child psychology, observed something profound about human nature. Our sense of ownership emerges incredibly early. Why are we so clingy? 

There’s a well-established phenomenon in psychology known as the endowment effect where we value items much more highly just as soon as we own them. In fact, in one experiment, neuroscientists scanned participants’ brains while they allocated various objects either to a basket labeled “mine,” or another labeled, “Alex’s.” When participants subsequently looked at their new things, their brains showed more activity in a region that usually flickers into life whenever we think about ourselves. 

Another reason we’re so fond of our possessions is that from a young age we believe they have a unique essence. Psychologists showed us this by using an illusion to convince three to six-year-olds they built a copying machine, a device that could create perfect replicas of any item. When offered a choice between their favorite toy or an apparently exact copy, the majority of the children favored the original. In fact, they were often horrified at the prospect of taking home a copy.

This magical thinking about objects isn’t something we grow out of. Rather it persists into adulthood while becoming ever more elaborate. For example, consider the huge value placed on items that have been owned by celebrities. It’s as if the buyers believed the objects they’d purchased were somehow imbued with the essence of their former celebrity owners. For similar reasons, many of us are reluctant to part with family heirlooms which help us feel connected to lost loved ones. But, sometimes our attachment to our things can go too far. Part of the cause of hoarding disorder is an exaggerated sense of responsibility and protectiveness toward one’s belongings. That’s why people with this condition find it so difficult to throw anything away.

Perhaps there will always be something uniquely satisfying about holding an object in our hands and calling it our own.

Control

There is nothing scarier than something that is out of your control..

Like cancer consuming someone you love so dearly and not being able to take the pain away..

It’s these types of situations that make you stop and realise how cruel life can be..

I’m so scared to lose you..

Whether that be soon or in years to come.. Just keep fighting and I will always be here to support you

In a study at UCLA, teenagers had their brains scanned while viewing pictures they had submitted. The more likes their photos had received, the more the reward circuitry in their brain lit up like a firework, much in the way that same area responds to chocolate, sex, and hard drugs. For people, attention (validation’s slutty sibling) can easily turn into pleasure-seeking behavior and, eventually, full-blown addiction. To our poor, stupid monkey brains, this is completely tribal. We see how many likes and comments and shares our posts get compared to those of other people, and we measure ourselves against them. If we have more, we are the king of the jungle. That social media stimulates this primal, addictive part of the brain is no coincidence. Companies like Facebook have never been coy about creating “obsession loops” that keep their users hitting refresh like it’s the button that releases the morphine.

However, unlike drugs or cigarettes, there doesn’t seem to be anything inherently harmful from getting some internet thumbs-ups, so why aren’t we all walking along like smiley happy people, having discovered a whole new way for us to feel good about ourselves? Because internet affirmation is an empty high, a whole lot of baby formula with not a lot of cocaine. According to Dr. Larry Rosen, professor of psychology at California State University at Dominguez Hills, real-life empathy is six times more effective at making people believe they are being supported. And our monkey brain is still advanced enough that it can tell the difference – so even a retweet storm will often leave us feeling hollow and emotionally malnourished. But on the flip side, a lack of likes hits just as hard as any real-life rejection. Not getting an instant positive click from a friend can quickly lead to feelings of resentment and anger. Many a Kimber-on-Kimber fight has broken out because of a poolside pic that was left unliked.

6 Ways Human Biology Turns You Into An Asshole On Facebook

Day 105

When I was eleven my brain was scanned (MRI) and two doctors talked to my parents, after I had left the room. I remember my mother crying and thinking that tears were caused by fear for I might have had a tumor.
It is so unusual, that after all those years, after all those time that has passed since my “professional” diagnosis, since the psychiatrist, it is now that I start to think about those things.

(-confession/lie 43)

Random thought. Both DiMA and Nick are voiced by Stephen Russell . So in story canon we can assume both prototypes have the same, probably more advanced voice modulator.

Does Nick sound anything like human Nick? Like he has that raspy ‘I smoked since I was legal’ texture to it. Is that because human Nick smoked? Is it because Nick the Synth smokes? Does smoking damage his robot voice box? Or is it from age? I doubt it’s age since DiMAs voice is a lot smoother. We know Nicks speech patterns are human Nicks and DiMA is very much none accented. Does Nick smoke because it feels familiar or did the brain scan also copy human Nicks addictions? Okay I need to stop.

Im relation to the brain scan ask, why can't they just get a bunch of diagnosed autistics V's allistics and scan their brains and look for a common occurrence? Isn't that how tests are done?

Well, yes, and they’ve done this. They didn’t find anything distinctive enough to use as a diagnostic tool or new theory. Researchers in the field will try this again with new tools, theories and perspectives. That’s their job. But absence of evidence isn’t evidence of absence, which is why I laid out a bunch of explanations for why no simple test has yet been found, and why one may not be found for a long time, that don’t undermine the idea of autism as “brains working differently”.

For context, there’s a few old theories about autism as being driven by either failures of parenting, or social and moral failures of the child. These were dismissive, harmful and inconsistent with later studies, and have (slowly) been slipping out of most discussion of autism. I respect the question, but I don’t want to give a sound bite that, out of context, sounds like I and this blog support those theories. So no, there isn’t a known way to consistently sort brain scans into “autistic” and “allistic” short of talking to the patients. And if we knew why not, we’d also know a lot more about where to look next than we do now.

some Fun New ADHD Facts if you haven't seen: last week the biggest-ever brain scan study of ADHD was done and found concrete differences in brain size between ADHD and non-ADHD brains! Overall smaller intracranial volume + differences in at least 4 areas. this article is p reductive - only discusses kids - and the full study is paywall'd but still!! www(.)cbc(.)ca/news/health/adhd-brain-structures-1.3983919

http://www.cbc.ca/news/health/adhd-brain-structures-1.3983919 is the news article.

You can read the study here: http://www.thelancet.com/journals/lanpsy/article/PIIS2215-0366(17)30049-4/fulltext

Too bad MRIs cost so much. We’d have a viable medical test to use for diagnosis. Which would make a lot of people shut up about whether or not it’s “real.”

wincest for the prompting thing. sam has a terminal disease?

I see you share my love of hurt!Sam anon, thanks for the prompt! It’s probably the upcoming episode but I immediately thought of Alzheimer’s. It’s still a terminal disease but sorry if you were expecting something more like cancer. 


Sam’s staring at the painting with a look of such reverence Dean doesn’t want to talk. Sometimes Sam needs time to appreciate the little things and like hell if he’s going to take that away from him. There’s not very much left to take anyway. 

But that’s what happens when your little brother’s brilliant brain decides to go and start killing itself off a few brain cells at a time. It doesn’t care he’s too young for this kind of shit to happen. 

Too fucking young. Dean’s lost count of how many times he’s said that. Screamed it at every doctor who held up the brain scans and shook their heads. 

Early onset. They’d try and say it as if that explains why his baby brother can recite fifteen exorcisms by heart but couldn’t figure out how to dial Dean’s phone number when he’d forgotten why he was in a gas station a month ago. 

Alzheimer’s is a bitch and early onset Alzheimer’s can go fuck itself in hell.  

Sam’s thirty-eight. They were never planning on living long enough to have to worry about this kind of shit. Arthritis and Dementia were things he safely assumed didn’t need to be worried about. But Sammy’s always had this kind of fucked up luck. 

Four months they’ve lived with this. Four months of Dean holding Sam so goddamn tight every night and holding his breath the next morning to see what would be forgotten today. 

It doesn’t work like that but it kind of does. 

They did the whole hunt side of it. Searched out every witch and spiritualist they could get their hands on but there wasn’t a lot that could be done. Still, Sam has a few talisman necklaces around his neck that promote memory that Dean had insisted he wear.  He needed to feel like he’d done something. 

But at the end of month three, Sam was getting more confused with all the different places they were always traveling to, starting to just hold Dean’s hand and shrug off explanations he wouldn’t remember. 

Dean had shut down everything then. Had done a U-turn in the middle of the empty highway and set off in the opposite direction, not willing to make Sam docile and powerless just because he couldn’t accept their new normal. 

And that line of thinking was how they ended up here. One thirteen hour plane ride with Dean on heavy sleep meds and face firmly pressed into Sam’s neck so he didn’t have to see out any windows- they had made it to Paris. 

He swears they aren’t starting a bucket list countdown but they kind of are. 

Sammy had wanted to see the paintings in the Louvre before he forgot about his art history classes and own studies. Dean couldn’t say no. 

“She’s beautiful,” Sam murmurs reverently, looking up at what appeared to the fifth naked woman with a screaming baby angel they’d seen. 

“Sure, baby.” Dean rolls his eyes and squeezes Sam’s hand. His brother grins and turns to meet his lips in a sweet kiss that has Dean feeling a lot more amicable to the painting. 

All the doctors said there’s not a lot of hope but Dean thinks there kind of is. 


Send me a prompt if you’d like! 

im not sure if i told you all this but ill say it again if i have because it’s good news

my mums brain scan results came back about a month ago and the tumour has shrunk and isn’t much cause for concern now

just a little note to everyone; no matter how bad things seem they always have the potential to be good in the end 💕

Does ADHD go away when you get older?
  • That depends. Some studies show that yes, some people do “grow out” of ADHD; however, lots of us don’t. Since ADHD is a neurodevelopmental disorder, it does make sense that some people would grow out of it; your brain is behind a bit to start and then it catches up.
  • One possibility with people who grow out of ADHD is that they’ve learned coping mechanisms that make it seem like they no longer have it, because their symptoms don’t cause them problems anymore. The studies mentioned above, however, are based on brain scans that show changes in the structures of the brains of those who grow out of ADHD.

So in discussing with @agentcalliope how we may one day see May join the No Chill ranks of Jemma ‘You mean, once we have sex’ Simmons and Elena ‘I like to go fast’ Rodriguez, we realized that LMD May seems to have slightly less chill than real May.  So I’ve come to the conclusion that, since Radcliffe got her brain scans when she was terrified and dying, Coulson was on her mind more than normal.  Like, if she really loves him the way I think she does, I feel like that would be all her mind is thinking about.  So the brain scan he got had way less chill than normal May and LMD May is in a permanent state of needing and wanting Phil Coulson and not being able to think of anything else.

Just sayin’
