What are Tinbergen’s “Four Whys of Behaviour”?
The four whys of behaviour according to Tinbergen are:
Causation
Development
Function
Evolution
(Four Whys of Behaviour) ——– refers to the mechanisms that cause the behaviour, such as hormonal, neural, or genetic factors.
Causation (Control)
(Four Whys of Behaviour) ——- focuses on how the behaviour changes over an individual’s lifetime, from birth to maturity.
Ontogeny (Development)
(Four Whys of Behaviour) ——- refers to the purpose of survival or adaptive value of the behaviour in the animal’s life.
Function (survival/adaptive)
(Four Whys of Behaviour) ——- looks at how the behaviour has evolved over generations due to natural selection.
Phylogeny (Evolution)
What is the fifth “Why” of behaviour
The fifth “Why” (Burgkhardt, 1997 ) is Private Experience - individual experience
A descriptive catalogue of behavours that occur within a species
Ethogram
2 Fixed action patterens
Rituals, Displays
Early Learning in a short critical period, irreversable, prefigures later responses
Imprinting
Learning without obvious reward
Latent Learning
Solving a problem through percieving interrelationships
Insight learning
behaviour (act) or structure which alters behaviour of others- effective because of receiver’s response
Signal
evolutionary process that stereotypes a cue into a signal
Ritualization
feature of the world, animate or inanimate, that can be used as a guide to future action
Cue
IGNALS: COSTS & HANDICAPS signal whose cost is greater than required by sheer efficacy (effectiveness)
Handicap:
– signal may be costly to produce (e.g. huge size, cheek flanges in adult male orangutans
loss of fitness resulting from making a signal
Cost:
signal whose intensity is causally related to quality being signaled & which cannot be faked
Index
(e.g., olfactory secretions used for marking)
signal whose reliability does not depend on its cost- i.e. not a handicap- & which can be made by most members of the population- i.e. not an index
Minimal-cost signal (e.g., communal troop defensive vocalisations)
a signal whose form is similar to its meaning
Icon (e.g. pointing)
a signal whose form is unrelated to its meaning
Symbol (e.g., language)
What are the two main themes of why chimpanzees are so intelligent
The need to navigate Social challenges and ecological problms
Studying behaviour can lead to an issue of
Observer Bias and Observer effects
Who revolutionised the study of animals - observation
