Document Summary

Learning chapter 2: nature of elicited behaviour, irritation of respiratory passages causes sneezing and coughing, behaviour occurs in response to stimuli elicited. Elicited behaviour = reflexive behaviour: concept of the reflex. Simple reflex responses are evident in many species. Papillary constriction to bright light: mammalian infants suck in response to object being placed near mouth, herring-gull chicks just as dependent on parental feeding, checks peck at tip of parent"s bill. Modal action patterns (map): response sequences typical of a particular species of particular species. Species-typical modal action patterns identified in many aspects of animal behaviour. Same stimulus have different effects depending on physiological state of animal and its recent actions. Species-specific action patterns as fixed action patterns to emphasize activities occurred pretty much the same way in all members of a species: eliciting stimuli for modal action patterns. Fairly easy to identify in case of simple reflexes: sequential organization of behaviour.
