Document Summary
Proximate (how/mechanical) causation the immediate sequence of physiological effects that lead to the behaviour. Ultimate (why/evolutionary) causation the adaptive value or evolutionary origins of the observed behaviour. Evidence for genetic component to behaviour: deprivation experiments prevents learning opportunities through isolation of subject, selection experiments constant environment, breed individuals with extreme phenotypes, measure next gen phenotypes. Change in mean behavioural phenotype = genetically based (eg/ dull and bright mice solving a maze: crossing genetic strains , molecular genetics. Instinct a behaviour pattern that reliably develops in individuals that receive adequate nutrition and that is given in functional form on its first performance. Imprinting structured learning; critical periods, life-long learning; often involves mating: classical conditioning trained have same response to different stimuli, operant conditioning (trial and error) Predisposition for associative learning has been shaped by evolution (eg/ rat; taste nausea, sound pain, taste--/-->pain) Direct fitness + indirect fitness = inclusive fitness.
