The other danger age is around eighteen. Guisinger believes at this age, dieting or exercise is most likely to cause the initial loss in weight that triggers anorexia.

The evolutionary aspect
If Guisinger is right, and some people have a biological mechanism that triggers starvation, the obvious question is why has it evolved? At first glance it would be counter-productive from an adaptive standpoint. Behaviours that result in death or reduce reproductive chances tend not to be favoured by natural selection!

Guisinger thought back to our distant evolutionary past and considered the conditions of the early humans in Africa. Droughts and famines would have been frequent. We know that early hominids had to migrate thousands of miles to find food. Guisinger believes that if she is correct then the following should all be identifiable:

Food associations: behavioural approach Because food is so vital we are efficient at learning associations between taste and consequence - when we taste food, we have expectations of the consequences. o Negative: we learn to avoid the food that makes us feel ill o Positive: we learn to associate the mood improving effects of carbohydrates, especially sugars, with sweet tastes

Evaluation General Methodological IDA's Contradictory Evidence Garg et al used typical cinema food for the high calorific snack which could effect the results as eating popcorn is associated with watching any film
Individual differences could have an effect as people may have a personal preference to what food they eat and therefore this may effect the results
depending on the time of day, before or after lunch will depend on how much each participant eats Application use as if you level out someones mood through therapy or drug you can reduce amount of comfort eating and change attitudes to food

Stress Stress influences our mood and in turn influences our eating behaviour. Stress = when the perceived demands made on people exceeds the perceived resources available for them to cope with such demands. Individual Differences hypothesis  differences in biology, attitudes to eating and learning history produce differences in vulnerability to the effects of stress. Those with high vulnerability respond to stress by eating more. Those with a low vulnerability to stress respond in a way that does not encourage eating. External and Internal Eaters: External eaters/ high
- Eat in response to food related stimuli irrespective of whether hungry/full
- Increased levels of stress increases eating in external eaters Internal eaters/low
- Respond more to internal cues to hunger when deciding when and what to eat
- Increased levels of stress reduce eating in internal eaters AO2 Research support - Connor et al: Procedure: 33 female and 27 male students took a daily record of the number and severity of daily hassles and the number of snacks consumed over 7 days. A questionnaire assessing eating behaviour given - restrained eating, emotional eating and external eating. Findings: The number of hassles reported by the participants was correlated with the number of snacks consumed but was moderated by external eating. Participants who scored highly on measures of external eating had a statistically significant positive relationship between hassles and snacking. The findings of this study therefore support the externality theory

In this essay we will present a brief synopsis of what psychology is and introduce the reader to the primary biological foundations of psychology that are linked to behavior as well as introducing the reader to the major schools of thought in psychology.

By four months of age, children being breastfed (which contains very low levels of salt) prefer cereals that are salty. Suggesting that not until this age does the taste seem to develop and by the age of two years children will reject food that they’re expecting to be salty that isn’t. The fact that this is universal again suggests evolutionary/biological mechanisms at work.

People with natural sodium deficiency find salt even more palatable than the rest of us and eat it in larger quantities when available. Dudley et al (2008) found that ants living further inland with less salty soils prefer salty foods to sweet. Again these studies suggest that we instinctively know that we need salt and have developed mechanisms that ensure we get sufficient. Apparently Scottish deer risk death on British roads by licking surfaces that have been gritted with rock salt in the winter months. However, in humans there are large individual differences which might not be expected from an evolutionary-driven behavior.


Why we eat meat
Gorillas are herbivores, chimpanzees and orangutans eat a little meat most modern day humans eat lots. Why this disparity?

Meat does bring advantages. It is high in energy, courtesy of the fat content, high in protein so is ideal for growth and repair and contains lots of vitamins and minerals, particularly the organs such as heart, liver and kidney. It is also available all-year-round which would have been a major advantage to our ancestors who would have had limited means of storing food for the winter months.
