Factors influencing attitudes to food and eating behaviour Flashcards
Factor 1: Early learning and experience
- Early learning shapes eating behaviour and food preferences
- Exposure to food, social learning, operant conditioning and classical conditioning explain how this learning occurs
Exposure to food
- Neophobia is the fear of new foods
- Many children show neophobic responses to food but by exposing a child to new foods it can change their preferences
- The mechanism of exposure suggests we like foods that are familiar with us.
Social learning as an explanation of eating behaviour
- SLT is observing others eating new foods and this subsequently impacts ones own behaviour
- There is an influence of role models, e.g. parents, peers, siblings, media - this is because they can easily identify with the role model
- Observing someone enjoying the food- vicarious reinforcement
- The child or individual may get praise for eating healthily
Operant conditioning as an explanation of eating behaviour
-A child would be praised from eating a particular food - positive reinforcement -> strengthens the behaviour
Classical condition as an explanation for eating behaviour
-An UCS (Praise) -> UCR (Happy)
UCS + NS (Healthy food) -> UCR
CS (Healthy food) -> CR (Happy)
Evaluation of early learning experiences: Birch supports classical conditioning
Birch found that rewarding eating with positive attention was effective in changing food preferences
-The adults are classically conditioned to be associated with the food and attention. The food has been classically conditioned response of adult attention, therefore the child will eat the food to have the adult attention
Birch et al. (SLT)
Birch et al used peer modelling to change children’s preferences for veg. This supports SLT because after the children viewed their peers eating different veg and enjoying them, it influenced them and they still ate the diff veg weeks after the experiment.
Methodological of birch et al.
- Did not account for social desirability (children could’ve lied to seem more healthy, or just said it because thats was they thought the researchers wanted to hear)
- Lacks generalisability
Strength of SLT
- It practical applications
- Lowe et al realised how children can be influenced by others and more exposure can lead to a more varied diet and so they conducted a study using ‘food dudes’ and it showed that the exposure to this caused significant changes in the children’s diets
Birch and Marlin (1982)
-The children were introduced to novel foods over a six-week period which showed a shift in their food preferences. This familiarises the child with the food which reduces neophobia, so the child learns to enjoy the food that they are exposed to
What evolutionary benefit did neophobia have?
Survival; the fear of new foods prevented us from eating harmful or dangerous foods
Nature in explaining the early effect of exposure:
- Neophobia prevents us eating dangerous foods that could lead to death
- Therefore exposing children to safe foods they know are safe will then increase their survival
Evidence for the role of nature by Benton
-Benton found that sweet foods are effective in reducing distress in very young babies, suggesting that babies may be born with innate food preferences
Factor 2: Mood, Including Stress
We may eat more to enhance our mood: If we feel low in mood, we may eat to cheer ourselves up
Garg et al
IV- whether they ate more in sad or happy films
DV- how much popcorn they ate in each film
They found that pps ate 28% more whilst watching films they considered to be sad. This supports mood enhancement as a factor for eating behaviour because it shows they ate more in order to cheers themselves up
