PSY352H5 Lecture Notes - Lecture 5: Mendelian Inheritance, Heritability, Pretectal Area
Document Summary
Prey capture: a 5 step process that is triggered by particula visual stimuli. February 7, 2018: orienting towards the visual stimulus, approach to be within striking distance, tongue strike to capture prey, mouth wipe. Prey capture circuit in the frog: numerous brain areas are involved. Heritability, genetic determinism, iq, sex, criminality & racism: when behaviour genetics is mixed with the dark side of political motivation, glayde whitney and james watson- (cid:498)those who are black have a lower iq(cid:499) If we know about their effects and if we study how they exert them, then we can design (cid:498)environmental(cid:499) programs to circumvent, augment, improve on their effects. In mendel"s experiment, it was shown that the seed texture trait segregated independently of the seed colour trait. How can we discover and study the effects of genes on behaviour: environmentally unmodifiable characteristics. Imprinting: behviour is not changed by repeat experience (eg. konrad lorenz + geese)
