Q

Factor 1: Early learning and experience

A
  • Early learning shapes eating behaviour and food preferences
  • Exposure to food, social learning, operant conditioning and classical conditioning explain how this learning occurs

Q

Exposure to food

A
  • 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.

Q

Social learning as an explanation of eating behaviour

A
  • 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

Q

Evaluation of early learning experiences: Birch supports classical conditioning

A

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

Q

Birch et al. (SLT)

A

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.

Q

Methodological of birch et al.

A
  • 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

Q

Strength of SLT

A
  • 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

Q

Birch and Marlin (1982)

A

-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

Q

Nature in explaining the early effect of exposure:

A
  • 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

Q

Evidence for the role of nature by Benton

A

-Benton found that sweet foods are effective in reducing distress in very young babies, suggesting that babies may be born with innate food preferences

Q

Factor 2: Mood, Including Stress

A

We may eat more to enhance our mood: If we feel low in mood, we may eat to cheer ourselves up

Q

Garg et al

A

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

Q

Methodological issues garg et al

A
  • Pps could’ve not liked popcorn
  • They could’ve eaten before the experiment
  • Because of the briefing they may have been trying to concentrate on the film
  • Not a large sample; lacks generalisability
  • Random sampling is good and individual differences have been accounted for through repeated measures
17
Q

Opiate hypothesis

A

-Neurotransmitters called endorphins (chemically similar to heroin) regulate activity in the brains reward pathways. These pathways make us feel good to encourage biologically important behaviours (such as eating + sex)

18
Q

Evaluation of the opiate hypothesis

A

Evidence for this explanation comes from research into naloxone. This drug blocks endorphins receptors; it reduces food intake, especially of sweet foods and suppresses thoughts about food.

  • We don’t eat much if we take naloxone because it blocks reward pathways, so the chemical pathway is blocked and we wont feel good about consuming the food
  • Eating cheers us up because a chemical response is released to make us feel good -encouraging survival
19
Q

GEM (General effect model)

A
  • The opiate hypothesis and studies such as garg et al, assume that eating causes common physiological changes in turn these lead to an increase in eating
  • We may eat more to cheer ourselves up, so we might eat more to make ourselves feel better when stressed

stress - > physiological change -> eating

20
Q

IDM (Individual differences model)

A

-This proposes that is will only happen with certain groups of people

Differences in learning, history, attitudes or biology;
High vulnerability to stress: Low vulnerability to stress:
->stress -> stress
Physical/ psychological change
-> promotes eating -> Does not promote eating

21
Q

Vulnerable groups to research are:

A
  • Emotional eaters: those who eat more during negative emotional states. May have learned to associate hunger and anxiety
  • External eaters: those who eat in response to external (sight) rather than internal cues
  • Restrained eaters: people who have to work to control their eating e.g. by dieting.
22
Q

In what ways is the IDM a more sophisticated model then the GEM

A

-It is a more sophisticated model because it accounts for individual differences and doesn’t assume that everyone stress eats

23
Q

Conner et al supports the IDM because…

A
  • They accounted for the different types of eating habits and the correlation between that stress eating
  • However it showed not significant correlation for the other types of eating habit and could argue it lacks support
24
Q

Conner et al methodological…

A
  • Social desirability bias - may have lied to seem healthy or did not stress eat
  • Ecological validity - real life
  • operationalises stress; daily hassles have more effect than major events
  • Connor et al. is only one study
25
Q

Lepper et al.

A
  • Told children a story of a mother offering tow made up foods to her children, independent groups
  • two conditions; non-contingent and contingent
  • NC= The foods were offered together but in different orders so receive one food regardless of the other, so reward is specified
  • C= They were told they could have one IF they had the other, so one was reliant on eating the other, so they will associate one food with reward behaviour.
  • They were then asked which foods they preferred.
  • The results showed that in the NC condition there was no particular preference, but in the C condition they preferred the food that was used as a reward.
26
Q

Lepper et al (behaviourism vs cognitive approach)

A

-The finding show that behaviourism is incomplete in explaining food preferences. The children have only listened to a story, so no learning via conditioning can have taken place. Rather, they work out that because it is used as a reward, that food must be preferable i.e the findings are due to their thought process- an explanation rooted in the cognitive approach

27
Q

Lepper et al evaluation

A
  • Well controlled study
  • There were two contingent conditions: the preference for the ‘reward food’ occurred when it was hupe or hule. This rules out the possibility that children just liked one word more that the other.
  • The NC condition was to show that without this reward system children have no particular preference for food. So it is strong evidence, emphasising the importance of the cognitive aspect of early learning.
  • Practical application = teaches people not to associate certain foods as rewards to their child wont prefer the unhealthy foods
28
Q

How does Lepper et al get around innate food preference?

A

When parents positively reinforce pudding by saying that the pudding will be a reward food. While this may encourage children to eat vegetables, the unintended consequence may be that it encourages pudding preference.
This can be difficult to investigate as reward foods are likely to be ones that we have an innate preference for anyway.
So Lepper et al used imaginary foods so the children have no preference for the foods.

29
Q

Lepper et al.

A

-28 pre‐school children were told a story about a child that was given 2 new foods (hupe and hule).
There were 2 conditions:
‐Non-Contingent: The children were told that the mother in the story offered their child first one
food, then the other‐having one food was not dependent on having the other.
‐Contingent: The children were told that the mother in the story said their child could have one food
if they ate the other‐having one food was dependent on having the other.

30
Q

What did Lepper et al. results show?

A

All of the children were asked which food they would prefer to have. The results showed there were no preferences in the non-contingent condition, however, in the contingent condition, the children preferred the food was used as a reward for eating the other food. Evidence suggests that pairing 2 foods in this way can lead to the reward food being viewed more positively to the food that provides
access to it.

31
Q

Evaluation of lepper et al.

A
  • Well controlled study
  • Two contingent conditions; the preference of reward occurred whether it was hupe or hule. This rules out the possibility of children just liking one word more than the other.
  • The non-contingent condition was to show that without this reward system, children have no particular preference for food.
32
Q

Practical application for Lepper et al.

A

-This can be applied in homes or by advertising to encourage to eat healthier by not rewarding children with pudding.

33
Q

Leshem (2009) cultural and nature and nurture

A
  • Leshem studied the diets of Bedouin Arab women living in desert encampments, Bedouin women who had lived for at least one generation in an urban setting and Jewish women in an urban setting.
  • The diet of urban Bedouins hardly differed from that of the desert Bedouins. Both groups differed significantly from the Jewish women.
  • The bedouin groups had higher intakes of carbohydrates and salt.
34
Q

How does the nature/ nurture debate arise in the Leshem study?

A

-This supports the idea that nature has a key element in our food preference as the Bedouins had extremely similar diets despite the fact they grew up in different environments.

35
Q

Conner et al (1999)

A
  • To investigate whether individual differences affects eating behaviour in stressed individuals.
  • 33 females, 27 males kept a daily record of the number and severity of daily hassles and snacks consumed
  • Asked to complete questionnaires assessing three dimensions of behaviour: restrained, emotional + external eaters.
  • High scorers on external eating had a significant positive relationship between hassles and snacking
  • No sig relationships were found for the other two behaviours
36
Q

Earling learning A01 support; Macintyre et al

A

Macintyre et al found the media did influence food preferences however this may then be limited by a persons own personal circumstances such as income, family, culture or even age.
