By studying screams recorded in a small, padded room, Frühholz and his team identified six acoustically distinct scream categories: pain, anger, fear, joy, passion, and sadness. Their research was published in PLOS Biology.
Screaming Conveys at Least Six Different Emotions
Interestingly, similarities between cries of joy and terror could have deep evolutionary roots. The findings may even provide a clue to the age-old question of why young children often scream while playing.
“Nobody has really studied why young children tend to scream frequently, even when they are happily playing, but every parent knows that they do. It’s a fascinating phenomenon.”
Humans also use screams to signal danger and to scare predators. But new research suggests that humans scream not only when they are fearful and aggressive, but also when they experience other emotions such as despair and elation.
In the past, scientific studies on human screams have focused almost exclusively on vocalizations of anguish—and this oversight nagged at neuroscientist Sascha Frühholz. He and his colleagues set out to characterize the screams we use for a range of emotions, negative and positive.
Frühholz and his team analyzed recordings of each scream by looking at 88 acoustic features, such as measurements characterizing pitch and intensity. They trained a computer algorithm on the various features that differed between screams and found it could correctly categorize screams nearly 80 percent of the time. The most accurate classification was for joy, with 89.7 percent correct classifications.
The team then studied participants listening to the recorded screams, measuring how quickly they could categorize the emotion triggering the scream by clicking an option on a computer screen.
In one set of trials, they tested people’s ability to select the scream type from all six emotions or neutral, and in another, the listeners only had the option of picking one of two scream types. The team also created maps of brain activity for people listening to playbacks of the screams using functional magnetic resonance imaging (fMRI).
Jody sue was in her cabin with her teenage kids 19 and 14 waiting for anything:
"we were kind of hyper alert because of property things that happened the day before so we were listening for noise everything was kind of quiet."
the sale brought a plethora of people to their door confused about which piece of land was for sale leading to a dispute of property lines:
"while we were out at one point doing survey lines and there was a flash of a car that went up
candace and donnie's driveway something about it struck me wrong"
she and her family next heard a truck door slamming and dismissed it as their neighbors, the next sound was harder to justify.
About an hour and a half before summer is thought to go missing jodie sue her son and her daughter heard something far more suspicious,
a scream:
"stopped all three of us cold"
her daughter was the first to go to the cabin door then all three were there listening still:
(JSB's Son)
"we heard just this kind of shrill almost animalistic scream"
JSB- "decided to go out look and see what we could see we went back onto the bank
didn't see anything, didn't hear anything"
they went on with their evening the kids returned to being kids jodie sue headed
down her driveway around six to tend to flowers
"and at this point i started hearing candace hollering for summer and then my brain immediately went you know scream earlier this uh oh"
jodie sue was the first to hear those calls and the first to join the search for summer:
"i dropped my purse i tried to yell at candace i was like i'm looking and i started looking"
jody sue searched one side of a creek summers
brothers the opposite side
you gave statements to the police right
oh absolutely
jody sue had been interviewed many times by investigators bringing up the scream often but the sheriff doesn't believe the scream is related to the disappearance of summer wells
she's been interviewed numerous times by not only my agency but the tbi and fbi and we don't find anything with that complaint or information related to this case.
Below is a clip, from what was one of Jodisue's self talk videos, from her car, on location in Rogersville (or her back yard maybe) to her invisible friends on the internet. I have no date for when, whether after, or before, the interview with WJHL.
Now I am a little stuck on, why was she so upset for Don and Candus mentioning "the neighbor said she heard a scream", when she was so flippant and non chalant and kind of weird, like super nervous. She goes from indistinct, undescri-->>babble scream, "sort of animalistic but not an animal", to "I heard Summer Scream!" ??
Start a sentence / statement / out loud thought/ with the phrase ...
"I don't know how to put it BUT--->>Look Guys"
what comes to my mind in those shoes, as I look down at ma new shoes, and I shuffles my feets, is, ... I need to do some 'splaining,
so ..... here comes some "snow" , sorry it's my job.
"I don't know how to put it, but Look guys,
So,... the day Summer went missing,..... my children and I heard her scream. uh... quite a while before she was reported, ....uhhh, missing, uhhhhh, And I was first on the ground, looking for her, um, at least below. "
