Overview Flashcards
Explanations of formation
Socio-biological and rewards/needs
Socio-Biological explanation
Evolutionary, best way to survive
Rewards/needs
Behaviourist, operant and classical conditioning
Explanations of maintenance
SET, Equity
SET
effect of costs and rewards, want to maximise profit
Equity
motivated to achieve fairness, maintnernace occurs from balance and stability
Explanations of Breakdown
Duck, Lee
Ducks model
stage theory
Intrapsycic, dyadic, social and grave dressing
Lees model
dissatisfaction, exposure, negotiation, resolution and termination
Relationship between sexual selection and reproductive behaviour
Sexually selected traits increase reproducrtive success, gender differences, inter and intra sexual selection
Sex differences in parental investment
investment increases chance of survival, females invest most but guaranteed maternity
Parent offspring conflict
children desire more investment than parents are selected to provide as have to allocate it to all offspring
Effects of early experience on adult relationships
Attachment styles, peers, culture
Attachment styles
secure attachment more likely to have stable satisfying relationships and insecure avoidant more likely to have trust problems
Interactions with peers
help develop social skills, from friendship groups individulas form relationships
Cultural influence
western choose on romantic attraction, other cultures have arranged marriage, collectivist and individualistic cultures, urban populations have more chances of meeting people
Factors influencing attitudes to food
mood, cultural influences and health concerns
Mood
stress can affect what we eat, mood often affects what type of food we eat
Cultural influences
different practices, traditions, special days and restrict certain foods. Transmitted to group by reinforcement and social learning
Health concerns
desire to avoid unhealthy foods, education is key and healthy foods have to be acessible
Restraint theory
cognitive boundary on foos often leads to episodes of overeating
Other explanation
unsustainable targets, concentration and ghrelin
Success of dieting
usually a combination, incentives and motivation, weight watchers and SLT
Biological explanations of eating behaviour
Neural mechanisms, hormones and set point theory
Neural Mechanisms
LH is hunger centre, VMH is satiety centre
glucose low- liver- LH- hunger- eating- glucose- VMH- satiety
Hormones
fat hormone leptin signals hypothalamus that calorific storage is high, so when levels low it gives rise to hunger
Set point theory
Everyone has own metabolic rate based on calorie consumption
Evolutionary explanations for food preference
sweet, salty, bitter and meat
Sweet preferences
preference is widespread, high energy and non toxic
Salty food preferences
necessary for body to function, keeps body hydrated
