Neuron

nerve cells that make up the nervous system

Parts of a Neuron

dendrites, soma, axon, axon terminal

Dendrites

receive info from other cells

Soma

keeps neuron alive

Axon

nerve impulse which is the in flow and out flow of particles

Axon Terminal

releases chemicals into the synapse called neurotransmitters which fit like a lock and key

Neurotransmitters

chemicals released by neurons

Anandamine

pleasant high from chocolate and marijuana

Seratonin

regulates mood, too little can lead to clinical depression, too much can lead to aggression, affects sleep appetite, PMS, peaceful love.

Dopamine

involved in addiction, hallucinations, and motivation giving you strong exciting feeling

Emotions

feelings which we literally feel because of the physiological change

Schactor and Singer

two factor theory of emotions saying that to have an emotion we must have a physiological change, then label the emotion because of x,y,z happening

Two Parts of the Nervous System

central nervous system and peripheral nervous system

Central Nervous System

brain and spinal cord, mental responses and cognition

Peripheral Nervous System

somatic nervous system (voluntary observable actions) autonomic nervous system (physiological responses)

Autonomic Nervous System

sympathetic nervous system and parasympathetic nervous system

Sympathetic Nervous System

higher heart rate, blood pressure, breathing, adrenaline, lowered digestion

Parasympathetic Nervous System

lower heart rate, blood pressure, breathing, no adrenaline release

Lazarus' Cognitive Theory of Emotion

Perceptions, expectations, values, cause emotions

4 Ways to Change an Unwanted Emotion

change perceptions on situation, change physiological response, change explanation for why you're having the response

Purpose of Emotions

motivate us, help people connect, and allow us to understand what we are thinking

Primary Emotions

basic emotions everyone everywhere are born with such as fear, anger, sadness, joy, surprise, disgust, and contempt

Secondary Emotions

variations and blends of emotion that vary from one culture to another or that depend on cognitive complexity

Nature Side of Emotions

primary emotions

Nurture Side of Emotions

secondary emotions

Facial Expressions and Infants

babies alter their behavior depending on the reaction or facial expressions of the people around them

Damage to the Left Prefrontal Cortex

person will be unable to respond to emotions of others, understand why they and others feel as they do, and adjust their own emotional responses appropriately

Regulation of Emotions

the prefrontal cortex regulates emotions helping us modify and control our feelings, and allowing us to respond appropriately to others

Mirror Neurons

brain cells that fire when a person or animal observes others carrying out an action; involved in empathy, imitation, and reading emotions

Reliability of Polygraphs

the lie detector isn't exactly reliable because there aren't physiological patterns of autonomic arousal specific to lying

Attributions

explanations that people make of their own and other people's behavior

Attributions and Emotions

emotions are often created or influenced by beliefs, perceptions, expectations, and attributions

Display Rules

social and cultural rules that regulate when, how, and where a person may express, or suppress, emotions

Emotion Work and Display Rules

display rules and emotion work go hand in hand because display rules state when you can express emotions and emotion work is the regulation of emotions

Stress

a psychological and physical response of the body that occurs whenever we must adapt to changing conditions, whether those conditions be real or perceived

Lazarus's View of Stress

one's view of a situation determines whether an event is experienced as stressful or not

Psychosomatic Illnesses

mental upset that triggers a physiological stress response, stress leading to measurable damage such as headaches, colds, cancer, asthma

Lazarus' Steps for Coping with Stress

disclaiming, escape-avoidance, accepting responsibility or blame, exercising self-control, seeking social support, positive reappraisal

Three Physiological Responses to Stress

the alarm phase, resistance phase, exhaustion phase,

Alarm Phase

body mobilizes the sympathetic nervous system to meet the immediate threat

Resistance Phase

body attempts to resist or cope with a stressor that cannot be avoided

Exhaustion Phase

persistent stress depletes the body of energy thereby increasing vulnerability to physical problems and illness
