Q

Berridge

A

Distinction between liking and wanting

  • can manipulate this with use of psychopharmological drugs
  • can have liking without wanting–> FI decreases + pleasantness, limited effect in hunger
  • or vice-versa, pre-meal hunger decreases, little effect on pleasantness and sweetness

54
Q

Flavour flavour learning Zellner

A

can be done, preference for sweet taste, sustained over 1 week

55
Q

Mere exposure effect

A

more oftern you are exposed more accepting you become of it

56
Q

MEF can be seen in self report but also..

A

Gallforic skin response

57
Q

Yeomans Chilli

A

people can tolerate chilli more (adaption?)

greater burn in lower dose, but still saying they are liking it

58
Q

neaphobia

A

fear of novel foods

59
Q

Eye-blink conditioning requirements

A

if you know puff associates with sound more sensttive to this effect, if you don’t know less sensitive

60
Q

how long does it take to digest a meal?

A

3 hours

61
Q

Booth conditioned learning of meal size in rats

A

association is formed between the sensory odour and the somatic cues that are present towards the end of the meal..
2 novel odours paired with either ED or dilute solution

62
Q

Booth humans

A

ppts who consume ED paired with novel flavour, after with have reduced in FI
on test day given solution of 35% with same flavour they will still eat less, some evidence of learning
BUT Zandstra failure to replicate

63
Q

how do we make decisions about portion size?

A

expected satiety and expected satietion, people able to discriminate between foods based on this

64
Q

Expectations can be conditioned

A

expected satiety greater in H/ED foods

65
Q

Expected-satiation drift

A

we expect novel foods to counter relatively little satietion untill experience tells us otherwise

66
Q

Corrupted learning

A
  • effect of non-nutritive sweetners–> rats put on weight (can’t use sweetness as a cue)
  • with sweetness learn, regulate other intake of food
67
Q

complexity of food

A

ED vary considerably in pizza

–> intact compensatory eating if know about the food

68
Q

what is inherited wisdom?

A

mothers diet effecting NBs eating. eg. garlic is mum exposed to garlic, baby more accepting
pass on adaptive aversion

69
Q

breast is best?

A

demand led feeding, baby is in charge learns self regulatory mechanisms

70
Q

how long should you breast feed for?

A

6ms

children who are weaned later, show greater acceptance of more foods when older

71
Q

Pica

A

opposite of neophobia

72
Q

social learning in food decisions

A

learning from watching others

73

75
Q

health concerns with obesity –>

A

type 2 diabetes, hypertenstion and myocardial infarction

76
Q

westernized diet more likely to be..

A

obese

indian study

77
Q

Problems with regulation of FI?

A

leptin deficiency

78
Q

Leptin

A

satiety hormone

79
Q

Ghrelin

A

hunger hormone (downregulated in obese people)

80
Q

Berthoud

A

2 seperate systems: 1. homeostatic (weaker) 2. non-homeostatic

81
Q

doubly labelled water

A

measure of ee

82
Q

Thrifty gene hypothesis, Veel

A

we put on weight by design, adaptive mechanism which allows us to store fat.

83
Q

Drifty gene hypothesis, Speakman

A

we get obeses by accident, no long be predated, so gene has drifted think of voles

84
Q

The protein leverage hypothesis

A

we need to consume protein, in order to defend minmum p level, need to eat larger meal to make sure we have enough
–> the rule of compromise

85
Q

Halesbarker hypothesis

A

conditions in which pregnant mothers are living in, prepare child for those living conditions (small babies, with slow metabolic rate) but born no famine, catch up period… predicitive of obesity

86
Q

Chaotic eating

A

ireegular eating, makes you more hungry

87
Q

Schacters externality theory

A

obese people –> more sensitive to external cues

lean people –> internal cues

88
Q

Manipulating time, schachter

A

obese indvididuals will eat more at the times of meals

89
Q

Nisbett, externaility and chronic hunger

A

obese on a indvidual level are not obese, within their biological constraints, the conquense of this is they experience extreme hunger
-obese in soceity/ environment, so try to restict diet, more senstiive to food cues

90
Q

Herman and Mack

A

Counter-regulatory eating, as they eat more loose restraint, loose motiviation

91
Q

Herman and Polivys

A

Boundary model of eating regulation
restrained eaters at the start are more hungry (dieting) so hunger is greater… satiety levels are pushed back–> subsquent ad lib will be greater

92
Q

disinhibition

A

factors that weaken our attempt to inhibit

93
Q

disinhibitors

A
  • physical threat
  • failure
  • public speaking –> increase FI in restrained eaters
94

dietary restraint

A

any attempt to limit intake

96
