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 What did Denton (1982) find in many varying animal species? Innate preference for salt 19 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 30 of 30
