BIO152H5 Lecture Notes - Lecture 16: Fixed Action Pattern, Instinct, Genetic Variation
Document Summary
Lecture 15 november 18, 2016: introduction to behaviour: what is behaviour, narrow definition: response to a stimulus. Innate behaviour: genetically programmed behaviour, no learning required, fixed action pattern (fap) Is a highly stereotypical innate behaviour pattern where a sequence of unlearned acts is linked to a simple stimulus: 3 characteristics. There is almost no variation in how behaviour is performed. Essential component of interaction between individuals and social groups. Innate behaviour is commonly observed in response to: Situation that have a high impact on fitness and demand a reflex like, fast, unlearned response. Imprinting: occurs during a specific stage in life. Irreversible: occurs only during a critical and sensitive period, spatial learning, esta(cid:271)lish(cid:373)e(cid:374)t of a (cid:373)e(cid:373)o(cid:396)(cid:455) that (cid:396)efle(cid:272)ts the e(cid:374)(cid:448)i(cid:396)o(cid:374)(cid:373)e(cid:374)t"s spatial structure, why animals behave the way they do.
