Q

compare intrinsic and extrinsic motivation

A

 Extrinsic motivation: external forces coming from outside oneself. Can include rewards for showing a desired behavior or avoiding punishment if the desired behavior is not achieved.
• Working hard for your boss at work.
 Intrinsic motivation: motivation that comes from within yourself. This can be driven by interest in a task or pure enjoyment.
• Ex: a student is interested in the work so he studies it, compared to extrinsic grades.
 Ex: children were allowed to draw and then were told about getting a gold start or not.
• Not told: just drew for fun  intrinsic
• Told: spent less time drawing  extrinsic

Q

instinct theory

A

early attempts to understand the basis of motivation.
 Instincts: innate, fixed patterns of behavior in response to stimuli. (can be consistent through life or disappear)
• Ex: wolves follow the leader of their pack or defend their territory
• Ex: children suck on their thumbs
Theory: people are driven to do certain behaviors based on evolutionarily programmed instincts.
• Some people believed that these instincts motivated people to do things.
• Others believed they could be overridden by experience.

Q

arousal theory

A

people perform actions in order to maintain an optimal level of arousal: seeking to either increase or decrease arousal so that it hits their optimal level.
 Arousal: the psychological and physiological state of being awake and reactive to stimulus
 Yerkes-Dodson law: postulates a U-shaped function between the level of arousal and performance.
• Performance is best at an optimal arousal level and it is worst at extremely high or low levels of arousal.
• Different levels of arousal are more beneficial for certain tasks.

Q

drive reduction theory

A

explains that motivation is based on the goal of eliminating uncomfortable state.
 Drives: internal states of tension that activate particular behaviors focused on goals.
 Drives are thought to originate within an individual without external factors.
 Help humans survive by creating an uncomfortable state, ensuring motivation to eliminate this state or to relieve the internal tension created by the unmet needs.
• Primary drives: include the need for food, water, and warmth, motivate us to sustain bodily processes in homeostasis.
o Homeostasis: the regulation of the internal environment to maintain an optimal, stable set of conditions.
 Controlled by negative feedback loops.
• Ex: thermostat
• Ex: hormones in the body. Many hormones are regulated by three-organ axes.
• Secondary Drives: additional drives that are not directly related to biological processes and are thought to stem from learning.

Q

need based theories

A

 Needs: motivators that influence human behavior.
• Motivation is how we allocate our energy and resources to best satisfy these needs. Motivation thus determines which behaviors are most important to pursue, how much effort will be taken, and for how long the effort will be maintained.
 Maslow’s Hierarchy of Needs: certain needs will yield a greater influence on our motivation
• Levels: physiological (highest priority, food), safety (body, employment), love/belonging (friendship, family), esteem (confidence), self-actualization (morality, creativity)
• If the lowest level of need is not met, motivation to meet that need will be the highest priority.
 Self-determination theory (SDT): SDT emphasizes the role of three universal needs: autonomy, the need to be in control of one’s actions and ideas; competence, the need to complete and excel at different tasks; and relatedness, the need to feel accepted and wanted in relationships.
• Must meet these needs to develop healthy relationships with oneself and others.

Q

Schachter-Singer Theory

A

NS arousal + cognitive appraisal ==> conscious emotion

both arousal and labelling of arousal based on environment must occur in order for an emotion to be experienced

 “I am excited because my heart is racing and everyone else is happy”

 Element of cognitive appraisal: to feel an emotion, one must consciously analyze the environment in relation to nervous system arousal.
 Experiment: a subject experiencing physiological arousal with no explanation or with misleading explanation will attribute the arousal to the surrounding environment, and label herself as happy or angry based on the behavior of the actor.
• Environment that encourages emotion + arousal = created emotion

Q

general adaptation syndrome

A

the sequence of physiological responses

physiological needs (bottom of the pyramid)
must satisfy these needs first.
94
Q

showing or feeling no interest, enthusiasm, or concern.

95
Q

what is Darwin’s opinion on emotions?

A

made the argument that emotions are a result of evolution and thus emotions and their corresponding expressions are universal.

96
Q

discuss emotions and culture

A

it is argued that emotions can vary by culture: different emotional experiences to certain things or reactions.

97
Q

before any of the 3 theories of emotion, what did early psychologists believe?

A

they believed that: stimulus => perception of negative stimulus => physiological arousal => behavior

98
Q

why was the james-lange theory incorrect?

A

by extension, it stated that in order to have an emotion there must be feedback from the peripheral NS. However, in spinal cord injury patients, they still expressed emotion, so this pathway could not be the case.

A

cognitive arousal theory

two-factor theory

102
Q

explain the Schachter-Singer Experiment

A

gave people epinephrine or placebo

told them or did not tell them about the drug and manipulated external cues

the misinformed and ignorant groups showed the greatest emotion because they attributed their physiological arousal to the surrounding environment.

A

According to Richard Solomon, (1974) the opponent process theory is a theory of motivation/emotion that views emotions as pairs of opposites. For example; fear-relief or pleasure-pain. When one is experienced (A), it triggers an opposing emotion after a period of time

The opponent process theory states that the more a person experiences the fear, the less the fear will affect them. This decrease in fear may continue to the point where the situation is no longer scary. If the stimulus (the thing feared) is no longer a fear, then a second emotion (relief) takes over
