Motivation Flashcards
Motivation
a need or desire that serves to energize or direct behavior; includes the influences that account for the initiation, direction, intensity, and persistence of behavior
Sources of Motivation: Biological Factors
food, water, sleep, sex
Sources of Motivation:
Emotional Factors
fear, panic, hatred, love, anger
Sources of Motivation:
Cognitive Factors
perceptions of the world, beliefs that you can/can’t do it
Sources of Motivation:
Social Factors
reactions from friends, teachers, family, media
Theories of Motivation:
Instinct and Evolutionary Theory
instincts are innate, automatic disposition towards responding in a particular way when confronted with a specific stimulus
Learning of species; specific behavior motivates organisms to do what is necessary for their survival
Problem with this theory is that it as not as common in humans as with other species. Humans have some institutional behavior at birth, but their instincts dissipate over first few months
Most psychologists believe that human behavior is directed by physiological and psychological factors.
Theories of Motivation:
Drive-Reduction Theory
Motivation arises from imbalances in homeostasis. When the balance of the equilibrium shifts we are motivated to try and right the balance.
Imbalance creates a need, brain responds by creating a drive and them prompts the organism to take action to satisfy drive
Need: Food
Drive: Hunger
Drive Reducing Behavior: eating
Theories of Motivation:
Incentive and Cognitive Theory
Needs push us into action
Incentive is the object we seek r the result we are trying to achieve through our motivated behavior. Incentives, positive or negative, pull us in one way or another to satisfy our needs. Drives push us to reduce needs, incentives push us to obtain them. Incentives are influenced by biological and cognitive factors
Extrinsic Motivation
Engaging in activities for external rewards. Reducing biological needs or helping obtain external incentives.
Intrinsic Motivation
Engaging in activities because they are rewarding and fulfill our beliefs and expectations
Theories of Motivation:
Optimum Arousal
Human motivation aims not to eliminate arousal but to seek optimum levels of arousal. We try to increase arousal when it is low, vice versa. There is an optimum level of arousal that is where performance on a given test is optimal. Yerkes-Dodson Law: we perform best when arousal is moderate
Maslow’s Heirarchy of Needs
- Self Actualization
4: Esteem
3: Love, belonging
2: Safety
1: Physiological
Hunger
Glucose levels affect hunger. Body is normally good at maintaining Glucose Levels, yet insulin decreases glucose in blood, lowering glucose levels, making us feel hungry. Levels in blood are monitored by receptor neurons in stomach, they send signals to brain, specifically hypothalamus
Hypothalamus
The part of the brain that deals with Hunger
Lateral Hypothlamus
responsible for feeling hungry
Ventromedial Hypothalamus
responsible for felling full
Set Point Theory
the weight at which your body finds stability. Weight tends drift around the level at which constellation of factors that determine food consumption and expenditure achieve an equilibrium
If weight is lost, food intake increases and energy expenditure decreases
If weight is gained, food intake increases and energy expenditure increases
Environmental Factors
Availability of Food: eat because the presence of food
Quantity: people tend to consume what is in front of them
Palatability: the better it tastes, the more people will eat
Eating by the clock: eat because its time to eat
Presence of others: people eat more in front of others
Learned Preference & Habitat
Different cultures illustrate the role they play in determining food consumption as well as when and what they eat.
Obesity
the condition of being overweight. BMI of 30 is obese
