1

James-Lange Theory-

The theory that emotional experience results from the brains perception of the pattern of autonomic and somatic nervous system responses elicited by emotion inducing sensory stimuli

2

Cannon-Bard Theory-

The theory that emotional experience and emotional expression are parallel processes that have no direct causal relation

3

Decorticate-

Lacking a cortex

4

Sham rage-

The exaggerated poorly directed aggressive response of decorticate animals

5

Limbic system-

A collection of interconnected nuclei and tracts that borders the thalamus and is widely assumed to play a role in emotion

6

Kluver-Bucy Syndrome-

The syndrome of behavioral changes that is induced in primates by bilateral damage to the anterior temporal lobes

7

Amygdala-

A structure in the anterior temporal lobe just anterior to the hippocampus; plays role in emotion

8

Polygraphy-

A pattern of mate bonding in which one male bondÕs with more than one female; the most prevalent pattern of mate bonding in mammals

9

Control-question technique-

A lie detection interrogation method in which the polygrapher compares the physiological responses to target questions with the response to control questions

10

Guilty-Knowledge technique-

A lie detection method in which the polygrapher records autonomic nervous system responses to a list of control and crime relate information known only to the guilty person and the examiner

11

Facial feedback hypothesis-

The hypothesis that our facial expressions can influence how we feel

12

Microexpressions-

a brief, involuntary facial expression shown on the face of humans according to emotions experienced. They usually occur in high-stakes situations, where people have something to lose or gain

13

Orbicualris Oculi-

facial muscle that is contracted during genuine smiles; encircles the eye and pulls the skin from the cheeks and forehead toward the eyeball

14

Zygomaticus major-

facial muscle that is contracted during genuine smiles; controlled voluntarily

15

Duchenne smile-

A genuine smile one that includes contraction of the facial muscles called the orbicularis oculi

16

Fear-

The emotional reaction that is normally elicited by the presences or expectations of threatening stimuli

17

Defensive behaviors-

Behaviors whose primary function is protection from threat or harm

18

Aggressive behaviors-

Behaviors whose primary function is to threaten or harm other organisms

19

Alpha male-

The dominant male of a colony

20

Target-site concept-

The idea that aggressive and defensive behaviors of an animal are often designed to attack specific sites on the body of another animal while protecting specific sites on its own

21

Septal aggression/rage

The behavior of lesioned rats (they are more aggressive)

22

Fear conditioning-

Establishing fear of a previously neutral conditional stimulus by pairing it with an aversive unconditioned stimulus

23

Medial geniculate nucleus-

The auditory thalamic nuclei that receive input from the inferior colliculi and project to primary auditory cortex

24

Contextual fear conditioning-

The process by which situations come to elicit fear through their association with fear inducing stimuli

25

Hippocampus

Affected by stress, plays a role in spacial location

26

Amygdala complex

plays a role in emotion and fear

27

Lateral nucleus of the amygdala

The nucleus of the amygdala that plays a role in the acquisition, storage, and expression of conditioned fear

28

Prefrontal cortex-

The areas of the frontal cortex that are anterior to the frontal motor areas

29

Stress-

The physiological response to physical or psychological threat

30

Stressors-

Experiences that induce the stress response
