latent inhibition is delayed learning to stimuli you have be prexespoded to

asked to catergorise picture of the animals or dinosaurs

p were asked to press when requited (they will learn either yeah or oop) based on feedback at the beginning they’d go at random but then have feedback

if latent inhibition happens then you would expect

youngest 4-5 didn’t have the ability to learn stimuli they had been prexspoded to

morris pool

sex differences between rats

blacked out around

previous studies suggest that male use geometry whereas use features

amended the shape of pool to make triangle

during training rats were trained with landmark placed right in front of point with platform so that rat would learn

in the test days the platform is removed, and rats are placed in the pool → timed how long they would spend time near either areas (landmark vs geo)

found male rats spend more time navigating in the corner angle than the female rats who spent more time around the landmark

supporting the idea that male rats prefer to learn shape than females who like to learn specific features

they learn both but rely on preferred

next study

rats were trained to find platform in the middle of platform in front of a - c

what happens if you change the position of landmarks e.g would it affect their navigation

they flipped where b is on the right and c is on the left (near landmarks) looked at how long they swam round the quadrant → b-c is the platform quadrant

when you flipped the near & far landmarks performance is disrupted → rats don’t spend time swimming in a central area they swim the whole thing compared to control

only flipped in the far didn’t effect the position

flipping

exp 2

both female and male rats spent time swimming in the platform quadrant but in inverted condition they spent equal time in the opposite quandrant

near landmarks are more important

(2020)

rats were trained using c on the right b on lefr and directional cue in front

in the inverted manipulation everything was rotated 180

in flipped manipulation a-c was filliped as well as B-d

in identity directional cue is removed

in exp a → results replicated swam around direction area

in inverted condition → performance was split between two quadrants which and the more time they spent in quadrant near directional cue was significant → suggesting how important directional cue is over landmark

in flipped condition → disrupted spending more time in directional cue compared to near

overall show that configural disruption regarding landmarks can prevent & directional cue is most important
