Document Summary
Basis of behaviour environment/genetic: learned behaviour --continuum--> genetic behaviour, epigenetic traits markers of dna (turns genes on and off) Evidence for a genetic component to behaviour: deprivation experiments, prevents learning opportunities through isolation of subject, squirrels burying, spiders web spinning, kangaroo rat, fixed action patterns. Pattern that appears, essentially complete and is played out to completion once activated by a simple sensory cue. Instinct: a behaviour pattern that reliably develops in individuals that receive adequate nutrition and that is given in functional form on its first performance. Learning a durable and usually adaptive change in an animals* - to experience by that - Call types: begging calls begging for food from parents, alarm calls given in presence of predator, contact calls maintain associations with parents/flock. Habituation repeated stimulae without appropriate feedback or unimportant stimulate (idle threats: habituates only to the unimportant stimuli. Imprinting structured learning; critical periods, life-long learning, often involves mating. Associative learning association of stimulate: classical conditioning.
