Human And Animal Communication Flashcards
Purposes for communication for animals
Survival
Reproduction
Territory
Food
Survival
- alarm calls to signal threat of a predator
- show their teeth, making themselves look bigger and growling to warn others to back away
- use calls to tell their young to wander away
Reproduction
- peacocks have colourful tails to attract a mate
- other animals may use colour to frighten or warn predators
Territory/ Food
- pheromones can be used to convey a variety of different messages including location of food
- rhinos use their poo to show their territory
Aim Von Frisch’s bee study
-to investigate how bees communicate the location of a food source to each other
Study design of Von Frisch’s bee study
- field experiment
- manipulates IV but limited control of EVs
Method of Von Frisch’s bee study
- food sources for a hive of bees were created by placing glass containers of sugar-water at different locations
- a hive with glass sides was used so the bees behaviour could be monitored; when bees visited sugar-water containers, they were marked with tiny spots of different colour paints to identify them when they return to the glass hive
- researched then observed their behaviour
What is a round dance
- turning rapidly in circles to right and then left
- used to show when food source was no further than 100 metres away from hive
Waggle dance
-when food source was further than 100 metres
Evaluation of Von Frisch’s bee study
- strengths- reliable as other people have recreated it and have found similar results, makes it more reliable
- weakness- glass hive is not natural
- lacks ecological validity
Properties of human communication not present in animal communication
- humans have gestures and an OPEN VOCAL SYSTEM
- humans communicate in past, present and future
What is displacement
Ability to communicate about things that are not present or events that have yet to happen in the future
