These are the essay plans we have learnt in our A2 Psychology class in the Eating Behaviour model. They are very brief as the are for revision and you will need to have learnt the information and studies first.

Biological Explanations of Eating Behaviour:

PARAGRAPH 1: Describe role of hypothalamus including evidence >>> Hetherington:> Lesions made on rats brains = Medial H is the satiety centre, laternal is feeding centre. Rats became obese as they were unaware of the satiety. Brobeck:> Lesions on lateral centre lead to loss of feeding. PARAGRAPH 2: Evaluation of that research e.g. problems of generalising from rats PARAGRAPH 3: Neuro transmitters and drugs. Norepinephrine = increased food intake, Serotonin = decreased food intake, Nicotine = decreased appetite. PARAGRAPH 4: Evaluation >>> Greenberg:> Surveyed energy intake and weight changes in P’s for a month. Cannabis users showed increased body weight, decreased when supply was removed. PARAGRAPH 5: Other approaches: use SLT, cognitive Psychodynamism evolutionary – your preference PARAGRAPH 6: Conclude: fetal programming (from evolutionary), oral personality, nature/nurture, blame culture, ethics
