baby presentation
Experiments
1
-->9 to 10 months = no fear if watchign videos of snakes vs otehr animals
--> testing which of the two likely
--> no differences in preferential looking = no spontaneous innate fear !!
-------------> non associative view /innate spontaneous = wrong
-
-
start toy moiving across screen<
--> then 3 sec attention getter right before start
--> twice during each clip a female voice = look at that!
2
7 to 18 month old = snakes = fear,
—> preferential loking task, looked longer at snakes when frightened human voice than if happy voice
———> maybe just more familiar with the other to know no harm lol huge limitation ?
--> direct test of associative bias account /predisposed for learning
--> auditory matching paradigm, matching sound to visual display --> expected if predisposition for fear then if they hear frightened voice they look at snake longer
-
12 movies (10sec)
--> 6 snake
--> 6 non snake
--> always snake non snake order #
audio = gibberish
‘Hat sundig pron you venzy. Fee gott laish jonkill gosterr’
--> played for 13 secs in total (3 before clip onset + full duration of it aka 10 sec)

3
ast study no difference in still images —> movement crucial
—> how old were these ?
---> what part of snake stimulus = elicits fear
--> its their slithering movement (sinusoidal)
-

Why do snakes elicit fear?
they dont know yet , green = proposition
so study to make that clearer
—> either innate spontanious
( non-associative view)
—> or predisposition to learn
(prepared learning theory /associative bias account)
snake and non snake randomly got paired and then randomly assigned to a voice :3!!= result all different snake non snake voice combinations
