Chapter 1 Flashcards
Ethologist
Scientist who studies animal behavior
Communication
Behavior intended to influence another organism
Conspecific
Member of some species
Four “f’s” of animal communication
Food, foe, friend, finding a mate
Food
Honeybee waggle dance
Karl von Frisch (1967):
Found that dance conveys direction and distance
Direction
Angle from vertical indicates angle from the sun
Distance
Length of waggle in the middle correlates with distance from the hive
Alarm call
Warns conspecifics of approaching predators
Vervet monkey calls for:
“Eagle”
“Leopard”
“Snake”
Dominance hierarchy
Social system in which each member knows who ranks above and who ranks below
Mother-infant bonding examples
- Rat pups emit ultrasound when they fall from their nest
- Human babies cry for their moms
Social grooming
- Picking fleas and dirt from fur
- Builds friendships
- Form of communication because it influences other’s behavior
Males advertise their genetic prowess to attract mates
- Peacock feathers
- Bullfrog croaking
- Birdsong
- Firefly lights
Females also advertise interest
- Mating rituals
- Pheromones
Features of Animal Communication Systems
- Limited range of expression
- Holophrases: refers to the entire situation, not specific objects or events
- Little ability to combine symbols to express novel ideas
- Here and now
Modes of human language
- Speech mostly resembles vocalized communication systems
- Writing has taken on its own form and conventions
- Sign languages are their own independent of spoken languages
Primacy of speech (Hackett, 1960)
Virtually all language use is in its spoken mode
Three features of language
-Rules
-Structure
-Arbitrary symbols-words are symbols bearing no resemblance to what they refer to
(Animal communication doesn’t have all of these)
Duality of patterning
- Structuring process that takes units at a lower level
- Combines them according to rules
- Form new units at a higher level
Pyramid scheme (Bottom to top)
- Phonemes-meaningless speech sounds
- Phonology-rules for combining phonemes
- Morphemes-basic units of meaning (root words, suffixes, prefixes)
- Morphology-rules for combining morphemes to form words
- Words-units of language
Syntax
Rules for ordering words into phrases and sentences
