Which 3 psychologists support the Dual Control Theory?
Lashley, Brobeck et al, Heatherington & Ranson and Anad & Brobeck
1 of 30
What did rats in Lashley, Brobeck et al's (1946) study have to do?
Negotiate a maze for food
2 of 30
What did they do to them?
Lesioned the LH in some, and VH in others
3 of 30
What was found?
Lesions to LH caused cessation of eating, and lesions to VH caused overeating
4 of 30
What did Heatherington & Ranson (1940) find that lesions to VH lead to?
Hyperphagia (overeating)
5 of 30
What did Anad & Brobeck (1951) find the lesions to LH lead to?
Aphagia (undereating)
6 of 30
Which psychologist goes against the theory?
Teitelbaum
7 of 30
What did rats have to do in Teitelbaum's (1957) study?
Push bar an increasing number of times to get food
8 of 30
What happened when VH was lesioned?
Initially worked hard, but became less willing and were fussy eaters if food was stale or bitter
9 of 30
Which psychologist supports the effects of NPY on EB?
Wickens et al
10 of 30
What happened when Wickens et al (2000) injected rats with NPY into hypothalamous?
Caused them to immediately start feeding, even when satiated
11 of 30
Who went against NPY?
Marie et al
12 of 30
What did Marie et al (2005) do to mice?
Genetically manipulated them to not make NPY
13 of 30
What was found?
No subsequent decrease in EB - may be an experimental artefact
14 of 30
Which 2 psychologists support the importance of sweet tastes?
Logue and Meiselman
15 of 30
What did Logue (1991) find about the human tongue?
Has specific receptors for detecting sweetness & have more sweet receptors than any other
16 of 30
What did Meiselman (1977) find about people of all ages?
Prefer sweet foods to any other tastes
17 of 30
Who supports the importance of salt?
Denton
18 of 30

Who supports the importance of meat?
Foley & Lee
20 of 30
When Foley and Lee (1991) compared primate feeding strategies and brain size what was found?
Meat eating led directly to a growth in human intelligence
21 of 30
Who went against meat?
Kendrick
22 of 30
What did Kendrick (1980) find to be a common factor in cultural groups noted for longetivity?
Vegetarianism
23 of 30
Which psychologist supports the avoidance of bitter tastes?
Go et al
24 of 30
Which bitter taste receptor gene did Go et al (2005) study in humans and 12 other primate species?
T2R
25 of 30
What was found about humans?
They accumulated more pseudogenes than other primates = bitter tasting capabilities have deteriorated
26 of 30
Who went against the idea that it is evolutionary to detect bitter and sour tastes?
Sandell & Breslin
27 of 30
What did Sandell & Breslin screen 35 adults for?
Bitter taste receptor gene htA52R38
28 of 30
What did they have to do?
Rate bitterness of various vegetables, some of which contained glucosinolates and some did not
29 of 30
What did those with the gene do?
Rated the glucosinolate containing vegetable as more bitter = goes against as should all find bitter
