Biological Psychology: Chapter 15 (Breedlove)

Front 1

THE JAMES-LANGE THEORY OF EMOTION

Back 1

Suggests that bodily responses evoke the emotional experience.
Therefore we experience fear because we perceive the body activity triggered by particular stimuli.

Front 2

THE CANNON-BARD THEORY OF EMOTION

Back 2

Suggests that the brain must interpret the situation to decide which emotion is appropriate.

Front 3

SCHACHTER'S COGNITIVE THEORY O EMOTION

Back 3

Schachter's Cognitive Theory
Suggests that the intensity of emotion can be affected by the bodily response and that the brain continuously assesses the situation.

Front 4

HOW MANY EMOTION DO WE EXPERIENCE? (PLUTNIK)

Back 4

8 different emotions or 4 paired opposites:
Joy Sadness
Affection Disgust
Anger Fear
Expectation Surprise

Front 5

WHAT ARE THE FACIAL EXPRESSIONS THAT ARE CONSIDERED UNIVERSAL

Back 5

Accourding to Ekman and Keltner (2000)
Anger, Disgust, Sadness, Surprise, Happiness, Contempt, Fear, Embarrassment

BELL'S PALSEY

Back 6

• Viral infection in the facial nerve
• Usually affects just one side
• Results in drooping eyelid and mouth
• No cure but most recover after a few weeks

Front 7

WHAT AREAS OF THE BRAIN ARE INVOLVED IN POSITIVE EMOTION?

Back 7

Positive brain sites are concentrated in the hypothalamas & extend to the brainstem
The Medial Forebrain Bundle- a collection of axons traveling in the midline region of the forebrain.
One important target for axons in the nucleus accombens.Dopaminergenic stimulation of this appears to be very pleasurable

Front 8

PAPEZ EMOTIONAL CIRCUIT

Back 8

A group of brain regions within the limbic system.
These interconnected regions known as the Papez circuit include mammillary bodies of the:
1. Hypothalamus
2. Anterior Thalamus
3. Cingulate Cortex
4. Hippocampus
5. Fornix
Later the Amydala and other regions were added.
These regions are now known as the Limbic System.

Front 9

THE LIMBIC SYSTEM

Back 9

Loosely defined, widespread group of brain nuclei that innervate each other to form a network. The nuclei are implicated in emotions.

Front 10

KLUVER BUCY SYNDROME

Back 10

Removed large part of the temporal lobes, found monkey's behavior dramatically changed after surgery.
Surgery had taming effect- no longer fearful of humans.Strong oral tendency- eating things they didn’t eat before.Hyper sexuality was another effect.
Why did this happen?
Amygdala- group of nuclei in the medial anterior part of the temporal lobe. Animals with amygdale lesions appeared to be much less fearful than control monkeys.
