Front 1

States of feeling (subjective) that can affect behavior - action oriented

Back 1

Emotions

Front 2

two dimensions of emotion

Back 2

Valence and Arousal

Front 3

positive valence =

Back 3

pleasant

Front 4

negative valence =

Back 4

unpleasant

Front 5

high arousal + positive valence =

Back 5

enthusiastic

Front 6

high arousal + negative valence =

Back 6

angry

Front 7

low arousal + positive valence =

Back 7

relaxed

Front 8

low arousal + negative valence =

Back 8

sad

Front 9

This part of the brain consists of bilateral almond shaped structures in the media-temporal lobe. Directly anterior to the hippocampus.

Back 9

Amygdala

Front 10

This part of the brain is critical for both the expression of fear, the experience of fear, and for recognition of fear in others. Represents a really high degree of specialization

Back 10

Amygdala

Front 11

Absence of the amygdala leads to

Back 11

tameness, hypersexuality in animals

Front 12

Visual Agnosia

Back 12

loss of ability to visualize objects

Front 13

Learned fear can occur from two different experiences

Back 13

Personal Experience and Modeling

Front 14

When rats have a brain lesions they lose the ability to connect the _________ with the ___________ so they ..

Back 14

don't know when the shock is coming

Front 15

Harry Harlow Experiment - scary robot showed us that

Back 15

Evolution has programmed you to be fearful of things we should be

Front 16

Rat with bilateral lesions of the amygdala

Back 16

lose their innate fear so they come out and get the food

Front 17

Fear Potentiated Startle: After Training a light and foot shock happens and the rat has a normal startle. but when just the light comes on the rat

Back 17

freezes

Front 18

Downer (1961) lesioned the monkey's right _______, disconnected the ___________ by cutting the _______ and other inter hemispheric structures

Back 18

amygdala
himispheres
corpus callosum

Front 19

In Downer (1961) what happens to the information coming through each eye? What behavior did the monkey display with left eye open? with right eye open?

Back 19

Info coming through right eye only goes to right hemi and info in left only goes to the left.

Monkey with left eye open was very aggressive.
When left eye closed, they became instantly calm.

Front 20

When the tone sounds in the rat information is sent to the

Back 20

Auditory Thalamus

Front 21

Hebbs rule

Back 21

cells that fire together wire together

Front 22

When the shock occurs in the rat the information goes to the

Back 22

somatosensory thalamus

Front 23

information converges at the ____ from there sends to the _________

Back 23

lateral amygdala
central nucleus

Front 24

if you lose the (central grey) periaqueductial grey you lose the

Back 24

freezing response

Front 25

Lateral Hypothalamus controls

Back 25

blood pressure

Front 26

Paraventricular Nucleus gives the (hormonal fear response)

Back 26

secretion of stress hormones, oxytocin

Front 27

"Low Road" (subcortical way)

Back 27

Thalamus to the Amygdala

Front 28

High Road (cortical processing)

Back 28

Thalamus to the Cortex to the Amygdala

Front 29

Hippocampus is important for

Back 29

encoding of the context

Front 30

located in the front of the brain and is activated when sees angry faces on the computer screen

Orbitofrontal Cortex

Front 31

Disgust is located in the
