Eating Behaviour Flashcards
1
Q
Mood
A
- affect eating habits, which can explain abnormal eating practices
- those that are more vulnerable to stress eat more
2
Q
Mood Evaluation
A
- mixed research
- is there a difference between acute and chronic stressors
- can help explain differences in eating behaviour
3
Q
Cultural Influences
A
- different cultures have different eating practices
- transmitted to group member by reinforcement and social learning
- special days and traditions such as pancake day
- some cultures restrict certain foods
4
Q
Cultural Influences Evaluation
A
- more often just play moderating role on other variable to determine eating behaviour
- eating behaviours are now more global and less based on individual cultures
5
Q
Health Concerns
A
- more often just play moderating role on other variable to determine eating behaviour
- eating behaviours are now more global and less based on individual cultures
6
Q
Health Concerns Evaluation
A
- other factors more influential, often override intentions to eat healthy
- some individuals unsure of how to act
- if it was key factor everyone would eat healthily
7
Q
Restraint theory
A
dieters place a cognitive boundary on food intake, however this often leads to episodes of overeating
8
Q
Restraint theory evaluation
A
- research support, most diets do fail, theory doesn’t explain those that do succeed
- methodologies have little relevance to real life
- often because we focus on food when dieting, casing people to eat more.
9
Q
Other explanation of failure
A
- unsustainable targets/ unrealistic goals
- ghrelin stimulates appetite, more prevalent when dieting
- lessening of concentration
10
Q
Explanations for success
A
combination of strategies, clear realistic goals
- motivation and confidence
- incentives/ social support (weight watchers)
- rewards
- social learning theory
11
Q
Explanations for success evaluation
A
- individual differences contribute to success rate
- ethical concerns restrict research, self reports often used
- gender bias
- can lead to formation of effective diet programmes
12
Q
Neural Mechanisms
A
- Hypothalamus plays vital role in food intake, LH is the hunger centre initiating eating behaviour and the VMH is the satiety centre that proud cues a feeling of fullness
- when glucose is low, the liver signals the LH which gives rise to hunger
- when eaten food releases glucose, activating the VMH, giving rise to satiety, stopping further eating
- particular foods eaten based on numerous other factors
- theory weakened when it was discovered rats with their VMH removed were still able to become hungry
13
Q
Hormones
A
- fat hormone leptin is secreted from fat cells in the blood, signalling the hypothalamus that calorific storage is high
- when people don’t eat enough leptin levels fall, brain detects this drop and interprets it as lack of calories so gives rise to huger
14
Q
Set point theory
A
- everyone has an individual metabolic rate there body is geared to generated by calorie consumption
- when people diet leptin levels decrease causing hunger pangs
- set point for obese individual is higher than for healthy one
15
Q
Set point theory evaluation
A
LH as “feeding centre” is an over simplification
not fully understood, part of very complex eating systems
allot of animal experimentation
cognitive factors play a role
allot of lab experiments
deterministic
