Motivation And Emotion Flashcards
Motivation
The driving force behind behaviour that leads us to pursue some things and not others.
Psychodynamic perspective of motivation (4 points)
- Emphasises the biological basis of motivations reflecting animal heritage
- Freud argued that we are motivated by internal tension states (drives) that build up until satisfied
- Two basic drives = sex (love, lust, intimacy) and aggression (control, mastery)
- Subsequent psychodynamic theorists argue for: need for relatedness to others and the need for self esteem
Unconscious motivation (3 points)
- Freud argued that a person can be unaware of their own motives for their behaviours
- Motivation can be unconscious (implicit) and conscious (explicit) at the same time
- Unconscious motivation can be assessed using protective tests in which a person describes a vague stimulus - eg. Ink blot test
Behaviourist perspective of motivation (5 points)
- Behaviours are governed by the environment
- Needs reflect a requirement such as food and water
- Drives are states of arousal that accompany an unfulfilled need (eg. Hunger/thirst)
- Drive reduction theory argues that we behave in order to satisfy needs and reduce drives.
- Drives can be “primary”.
Cognitive perspective of motivation:
- expectancy value theory
- outcomes are…
- conscious goals….
- “Expectancy - value theory” = motivation is a function of the value people place on an outcome AND the extent to which they think they can achieve it
- Outcomes are viewed as goals which are established through social learning
- Conscious goals regulate much of human behaviour
Drive reduction theory/cycle (5 steps with explanations between each)
Homeostasis (state of biological equilibrium)
- Biological need occurs
Biological need = food/water
- Need gives rise to drive
Drive = internal state of tension
- Organism motivated to satisfy drive
Goal directed behaviour (action taken)
- Drive reduced
Need satisfied (hunger/thirst relieved)
- Balance restored
> > > > > back to homeostasis
Components of cognitive theory of motivation
- intrinsic motivation
- self determination theory
- implicit motives
• Intrinsic motivation: refers to the enjoyment of and interest in a behaviour for its own sake
• Self determination theory: 3 innate needs = competence, autonomy, relatedness.
Fulfilment increases intrinsic motivation
• Implicit motives: are those which are activated and expressed outside of conscious awareness
Humanistic perspective of motivation (1 theory with 5 parts)
Maslow’s hierarchy of needs:
(In order of most important)
- physiological (hunger/thirst)
- safety (housing/money)
- love/belongingness (intimacy)
- esteem (respect from peers)
- self actualisation (creative art/service to others)
Evolutionary perspective to motivation (3)
- Early theorists suggested behaviour was governed by INSTINCTS: fixed patterns of behaviour produced without learning.
- Key assumption is that motivational systems serve functions that may have evolved independently in response to particular evolutionary pressures.
- Contemporary theorists argue that there are multiple motivational systems related to SURVIVAL and REPRODUCTION
Eating
Definition and process
Eating is a behaviour in which we consume food to supply energy, minerals and vitamins to the body.
Ingestion of food leads to a sequence of metabolic events:
• absorptive phase - food is ingested, energy is extracted and stored as either glycogen or fat.
• fasting phase - glycogen is covered to glucose for use by the body
Homeostasis
Definition and how eating is a part of homeostatic process
The tendency of the body to maintain constancy of the internal environment.
Eating is a part of a complex homeostatic process with:
- set points: biologically optimal level system tries to maintain
- feedback mechanisms: e.g. Receptors to monitor level of sugar in blood
- corrective mechanisms: these restore system back to set point when needed.
What turns hunger on? (2 different things)
- Physiological hunger is caused by dropping levels of glucose and lipids in the bloodstream (detected by brain and liver).
- Hypothalamus plays a central role:
• lateral hypothalamus plays role in switching ‘on’ eating behaviour.
• ventromedial hypothalamus plays role in switching ‘off’ eating behaviour
How the role of hypothalamus in eating came to be known
Decades ago, researchers began studying the roles of the ventromedial hypothalamus and lateral hypothalamus in eating.
Destruction of the ventromedial hypothalamus can lead to obesity in rats.
External cues in eating (4)
Things that affect how much/if people eat
- food palatability: tasty foods can motivate eating
- food variety: exposure to the same food day after day can reduce intake
- time of the day: if eating is at the same time each day, conditioning can occur.
- presence of others: meal size increases as the group size increases.
Obesity (definition and 2 x types of consequences)
Obesity is defined as a body weight of 15% or more above the ideal for ones height and age.
Consequences of obesity:
Physical - heart disease, diabetes, stroke, early mortality.
Psychological - negative stereotypes about the obese, discrimination, difficulty in relationships, low self esteem.
