Thank you We sneak and here's your shmoop du jour

00:05

brought to you by lazy boy psychology it's like armchair

00:08

psychology but specifically practiced by people who just want to

00:11

sit back watch the game eat some guac and give

00:14

opinions They're wildly unqualified to make All right here's the

00:17

question What is the bobinsky reflex in here A potential

00:22

answers are Well as you may have guessed by the

00:27

first word of literally every single answer that babin steve

00:30

reflex deals with babies there are actually quite a few

00:33

of these baby reflexes probably because people love watching babies

00:36

even though they don't really do anything except with poop

00:39

and yelling stuff But hey if we wanted to watch

00:41

that we'd hang out with our great great grandfather Other

00:45

examples of newborn reflexes or primitive reflexes to use the

00:48

more formal title include route reflects suck reflex morro reflex

00:54

01:00

max trainer m five well that last one isn't really

01:03

reflects Absolutely just making sure you're listening So which of

01:06

these is the bobinsky reflects well not sucking their thumbs

01:09

as you might have guessed that one is the creatively

01:11

names suck reflects and actually babies will suck anything that

01:15

touches the roof of their mouth as well Any mammal

01:18

really there's a reason doctors air stressed all the time

01:21

it's because they can't get their tongue depressors back from

01:23

patients It's also not answer d you might have thought

01:26

he was the grasp reflex we mentioned earlier but the

01:28

grasp reflex On ly deals with objects that stroke the

01:31

palm it's sort of like a suck reflex of the

01:34

hand and if you don't grow out of it it

01:35

makes for some pretty awkward first dates that leaves answers

01:39

a b and c We can eliminate me because it's

01:41

not true Well it's not true about human babies Anyway

01:44

Armadillo babies instinctively coil into their patented fear balls straight

01:48

from birth but human babies actually extend their arms and

01:52

legs wind startled and then cry a lot quick Psa

01:56

if you're going to start a one always choose the

01:58

armadillo so that leaves us with a and c cheeks

02:02

or feet which one screams bobinsky on The answer is

02:05

a named after the french neurologist josef bobinsky Bobinsky reflects

02:10

describes the way babies will spread their toes in response

02:12

to being stroked on the soul of their foot Looks

02:14

like angsty teenagers aren't the only ones who can appreciate
