Document Summary
[before, before and during, during, or just after] the unconditioned stimulus [food]. Well-known studies with dogs (2: overmier & seligman (1967) learned helplessness, phase 1 all dogs harnessed still in shock box. Why study dogs comparative cognition: sometimes chimpanzees etc. are studied to understand humans because they are close relatives. 50,000-25,000 years ago proto-domestication of wolves: wolves that are more willing to get close to humans are more likely to scavenge leftovers: ca. 15,000-10,000 years ago early domestication: humans start to enclose villages, separating the proto-dog population from wolves, and to mix agriculture with hunting and gathering: ca. 7000-5000 years ago early selection: humans start favouring dogs suited to particular roles: ca. 3000-2000 years ago more deliberate cross-breeding: even more recently pure breeding. Hepper, 2003), sampling 3-5 footsteps (hepper & wells, 2005: no direct evidence, but presumably scent concentrations differ, despite the short time 4 steps take, visual navigation problems are more easily studied
