What are Tinbergs 4 questions in regard to a behaviour and their causation?
Causation: sensory system, hormones and nervous system. Development: genetic and developmental mechanisms. Adaptive advantage: increases animal fitness. Evolutionary history: how it evolved.
What are genetically determined fixed action patterns?
Stereotypic behaviours that are performed without learning.
What is a learned fixed action pattern?
A behaviour taught by parental figures and one that has to be learned throughout an individuals life.
What is behavioural plasticity?
A change in an individuals behaviour as a result of environmental stimulus
What are the proximate explanations of behaviour?
Causation (mechanism) and development (ontogeny)
What are the ultimate explanations of behaviour?
Adaptive advantage (function) and Evolutionary history (Phylogeny)
How can Cost-benefit be used to investigate behaviours?
Animal should not perform behaviours that cost more than the benefits they provide. Assumes animal has a limited amount of time and energy. assumes there is a trade off between engaging in one behaviour over another.
