2 problems with amateur animal behaviourists
perceptual bias, anthromorphism
humans often see what we expect to see
see pattern where no pattern exists
humans anthropomorphise
ascribe human characteristics to things not human
attributes ute conscious thought to animals too quickly
what makes a professional behavioural scientist
proper use of scientific method
3 reasons to why study behaviour
understanding evolution of adaptions, knowledge for conservation and origin and functions of human behaviour
hypothesis
priori statement of simple relations between cause and effect, consequences or outcomes which are measurable or can be manipulated
models with testable and quantitative parameters
scientific method
observations, questions, hypotheses, tests (experiments), interpretation
problem with professional behaviourists
perceptual bias still possible
ethology
study of animal behaviour with emphasis on the behavioural patterns that occur in natural environments
behavioural ecology
emphasises evolutionary hypotheses, based on the fact that animals will act in a way that will increase their darwinian fitness
evolutionary fitness
measures how many viable, fertile offspring an individual leaves in the next and subsequent generations, relative to others in the population
adaptive behaviour
increases individuals evolutionary fitness relative to other individuals in the population
what is Tinbergen’s 4 whys
4 ways of answering a ‘why’ question about animal behaviour, all 4 must be answered to fully understand any behaviour
Tinbergen’s 4 ways
proximate (mechanistic), developmental (ontogenetic), phylogenetic (historical), functional (ultimate)
proximate - Tinbergen
what motivates an individual to act in a particular way at a particular time
developmental - Tinbergen
why does an individual behaviour in a particular way
phylogenetic - Tinbergen
why did the behaviour arise in the first place and follow that evolutionary path
functional - Tinbergen
why does the behaviour increase the individuals ability to survive and reproduce
innate knowledge
automatic, inherent, no learning trajectory
no variation in behaviour among individuals
present in all members of the species
