Document Summary
Genetic contributions to motivated behaviour part one. Innate releasing mechanism: a system that needs to be activated prior to a behaviour happening. Long days and plentiful food supply for mating ensures higher chance of survival. Key/sign stimulus: environmental cue that triggers the consummatory behaviour (a behaviour that must be completed from start to finish drive: can be a supernormal stimulus to determine what triggers the behaviour, sex, defensive attack (protection) Fixed action pattern: innate behaviour, genetically produced through species (rare in humans) generally consisting of reproductive behaviours. Female peacock male tail female squatting copulation. Fixed action #1 fixed action #2 fixed action #3 fixed action #4. Elicited behaviours are a response to a certain stimulus. They are simpler then a fixed action pattern but also involve an adaptive behaviour. January 25, 2018: thermotaxis, negative/positive, moths with light (heat and light adaptation) seemingly goal directed behaviour that is actually reflex. Babinski reflex feet splay with pressure.
