5: Motivation, Emotion, & Stress Flashcards
(34 cards)
Intrinsic motivation
Driven by interest in a task or pure enjoyment
Instincts
Innate, fixed patterns of behavior in response to stimuli
Instinct theory of motivation
People are driven to do certain behaviors based on evolutionarily programmed instincts
Father of modern psychology
William James
Arousal theory
States that people perform actions in order to maintain an optimal level of arousal; seeking to increase arousal when it falls below their optimal level, and decrease arousal when it falls above their optimum level
Yerkes Dodson law
postulates a U-shaped function between the level of arousal and performance
Drives
Internal states of tension that activate particular behaviors focused on goals
- Drives help humans survive by creating an uncomfortable state, ensuring motivation to eliminate this state or relieve the internal tension created by unmet needs
Primary drives
Need for food, water, warmth
Secondary drives
Not directly related to biological processes and thought to stem from learning
- include emotions, such as desire for nurturing, love, achievement, and aggression
Drive reduction theory
Explains that motivation is based on the goal of eliminating uncomfortable states
Maslow’s hierarchy of needs
- Five groups, each assigned different priority
- Most primitive, essential needs are at the base; first four levels correspond to physiological needs, safety and security, love and belonging, and self-esteem
Self determination theory (SDT)
- emphasizes the role of three universal needs: autonomy (need to be in control of one’s actions/ideas), competence (need to complete and excel at difficult tasks), and relatedness (need to feel accepted and wanted in relationships)
Incentive theory
Behavior is motivated by desire to pursue rewards and avoid punishments, not by need or arousal
Expectancy value theory
The amount of motivation needed to reach a goal is the result of both the individual’s expectation of success in reaching the goal and the degree to which he or she values succeeding at that goal
Opponent process theory
Explains continuous drug use
- This theory explains that when a drug is taken repeatedly, the body will attempt to counteract the effects of the drug by changing its physiology
Tolerance
Decrease in perceived drug effect over time
Three elements of emotion
- Physiological response: changes in HR, BR, skin temp, BP
- Behavioral response: facial expressions and body language
- Cognitive response: subjective interpretation of the feeling being experienced
James-Lange theory of emotion
A stimulus results first in physiological arousal, which leads to a secondary response in which the emotion is labeled
- This theory predicts that individuals who cannot mount a sympathetic response should show decreased levels of emotion
Cannon-Bard theory of emotion
States that the cognitive and physiological components of emotion occur simultaneously and result in the behavioral component of emotion, or action
- this theory fails to explain the vagus nerve
Schachter-Singer theory of emotion
Aka cognitive arousal theory (or two factor theory)
- states that both arousal and the labeling of arousal based on environment must occur in order for an emotion to be experienced
(I.e. I am excited because my heart is racing and everyone else is happy)
Limbic system
A complex set of structures that reside below the cerebrum on either side of the thalamus
= amygdala, thalamus, hypothalamus, hippocampus, and fornix, septal nuclei, and parts of the cerebral cortex
Amygdala
Signals the cortex about stimuli related to attention and emotions
Thalamus
Sensor processing station that Relays info to appropriate areas of the brain, such as the cortex
Hippocampus
- Within temporal lobe
- Primarily involved in creating long-term memories
