Chapter 10 | Emotion and Motivation Flashcards
Emotion (Affect)
An immediate, specific negative or positive response to environmental events or internal thoughts.
Typically have a triggering event & prompt changes in thought and behavior.
Three components -
- Physiological response (heart beating fast, sweating)
- Behavioral response (eyes/mouth opening wide)
- Bodily states based on feelings
Involves the activation of the autonomic nervous system to prepare the body to meet environmental challenges.
Feeling
The subjective experience of the emotion (being scared) but not the emotion itself.
Mood
Diffuse, long-lasting emotional states that do not have an identifiable trigger or a specific behavioral and physiological response.
Refers to people’s vague senses that they feel certain ways.
Feeling V. Mood
Getting cut off in traffic can make a person angry (emotion), but for no apparent reason, a person can be irritable (mood).
Primary emotions
Innate, evolutionary adaptive, and universal emotions.
Examples - anger, fear, sadness, disgust, happiness, surprise, contempt
Secondary emotions
Blends of primary emotions, feelings about emotions, or emotions that relate to culturally specific values or concepts.
Examples - remorse, guilt, shames, jealousy, pride, love, contentment
Circumplex model
One system in which emotion is classified.
Emotions are plotted along two continuums - valence (how negative or positive they are) & arousal (how activating they are).
Arousal
Generic term used to describe physiological activation (increased brain activity) or increased autonomic responses (quickened heart rate, increased sweating or muscle tension).
Valence V. Arousal
Examples -
- You lost a $1 bill in your pocket. This makes you unhappy, so you will judge it to have negative valence. Might make you slightly aroused.
- You find a million dollar lottery ticket. This makes you very happy, so you will judge it to have positive valence. Your arousal will probably skyrocket.
Limbic System
(1937) Neuroanatomist James Papez proposed that many subcortical brain regions are involved in emotions.
(1952) Physician/Neuroscientist Paul MacLean expanded the list of regions and called it the limbic system.
Many limbic structures are not central to emotion & many brain structures outside are involved in emotion.
Used in a rough, descriptive way rather than as a means of directly linking brain areas to specific emotional functions.
Insula
Receives and integrates somatosensory signals from the entire body.
Involved in the subjective awareness of bodily states, such as sensing your heartbeat, feeling hungry, or needing to urinate.
Particularly active when people experience disgust or observe facial expressions of disgust in other people.
Activated in emotions including anger, guilt, and anxiety.
Amygdala
Processes the emotional significance of stimuli and generates immediate emotional and behavioral reactions.
(Joseph LeDoux) The processing of emotion in the amygdala involves a circuit that has developed over the course of evolution to protect animals from danger. Most important brain structure for emotional learning.
People with amygdala damage do not develop conditioned fear responses to objects associated with danger.
How information reaches the amygdala
- “Quick and Dirty” System - processes sensory information nearly instantaneously. Travels quickly through the thalamus directly to the amygdala for priority processing.
- The Slower Path (More deliberate & more thorough evaluations) - sensory material travels from the thalamus to the cortex. Information is scrutinized in greater depth before it is passed along to the amygdala.
Fast system prepares animals to respond to a threat in case the slower pathway confirms the threat.
Example - You shied away from a blurry movement in the grass only to realize it was the wind and not a snake.
What is the amygdala involved in?
Emotional events stored in memory.
The perception of social stimuli.
Emotional content of facial expression.
Polygraph (Lie Detectors)
An electronic instrument that assesses the body’s physiological response to questions.
Records numerous aspects of arousal, such as breathing rate and heart rate.
Used to determine a person’s level of emotionality (autonomic arousal) when confronted with certain information.
Example - Lying is stressful for most people, so autonomic arousal should be higher when people are lying than when they are telling the truth.
How is the polygraph flawed?
Physiological arousal is not specific to lying. People may become nervous because the procedure is new and scary or they’re upset because someone thinks they’re guilty when they’re innocent.
The polygraph cannot tell whether or not a response is due to lying, nervousness, or anything else.
They are easy to cheat by counting backward by sevens or pressing your feet to the floor during critical questions.
Interviewer must rely on their judgement whether or not the arousal indicates deception. Judgement is influenced by the investigator’s preexisting beliefs.
James-Lange Theory
A theory of emotion stating that people perceive specific patterns of bodily responses and as a result of that perception feel emotions.
Cannon-Bard Theory
A theory of emotion stating that information about emotional stimuli is sent simultaneously to the cortex and the body and results in emotional experience and bodily reactions, respectively.
