What is Piaget’s theory of language and thought?
Piaget thought that children develop language by matching correct words to their existing knowledge. This means that understanding comes first and then language. Language can only be used at a level that marches our cognitive development.
Sensorimotor stage
0-2
Babies just copy sounds they heard others making
Pre-operational stage
2-7
Children use language to voice their internal thoughts, rather than communicate with others
Concrete stage
7-11
The ability to use language has developed a lot but can only be used to talk about actual concrete things
Formal operational stage
11+
Language can be used to talk about abstract and theoretical ideas
Eval of Piaget’s theory
:) I explains how language development is not random. When children start talking they often use two-word phrases e.g ‘Mummy sock’ This shows that children understand the relationship between people and objects before they can talk properly.
:( Piaget’s theory has been criticized because of the way he collected data. He used his own children and small samples that are representative of most children. This reduces the generalizability of the results gathered from the research.
Sapir-Whorf hypothesis
t suggests that our thoughts and behaviors are affected and formed by the language we speak. This means that cultures with different languages also have different ways of thinking and understanding things.
Eval of Sapir Whorf
:) Many languages in Native America dont have separate words for blue and green, and research has found that English speakers perceive bigger differences in shades of blue and green (e.g the russian language has different words for igniter and darker blues and they are quicker at spotting this difference)
:( People who grow up not able to talk or who lose the ability to talk are still able to think. This suggests that language doesn’t determine thought and that understanding comes first as piaget suggested.
Variation in recognition of color
The language we speak can lead us to focus on certain ways of seeing things and make some ways of thinking more likely than others
(e.g native americans with blue & green)
Variation in recall of events
Researches studied how English speakers and Spanish speakers described intended and accidental actions. Participants were asked about seeing someone accidentally bump into and knock a vase to the floor. When the action was intended all participants identified the person doing it. But when it was accidental, the English speakers identified the person more than spanish speakers.
4 main functions of animal communication
Survival
Reproduction
Territory
Food
Survival
The vervet monkey sound a specific alarm call to warn other monkeys that a particular predator is around. This means the alarm call increases survival as other monkeys will run or hide.
Reproduction
To attract a mate, male peacocks use a mating display to signal to female peacocks that they want to reproduce. This communicates the male’s genetic fitness- bright feathers represent good health.
Territory
Many animals mark their territory using the signal of scent marking. using their urine, they discourage other animals from invading their territory. This is a better way to show dominance that having to fight to defend territory.
Food
Many animals use signals to draw attention to found sources. Bee’s use dance like movements to communicate how far away food is to the rest of the hive. When close, bee’s fly in a round dance, when further away they perform a waggle dance.
Von frisch’s bee study: aim
To investigate how bees communicate the location of a food source to each other.
Von-frisch’s bee study: method
Gas’s containers filled with sugar water were placed at different locations. A hive with glass sides was used to enlist observe the bee’s behavior. When the bees visited the containers of sugar water to feed they were marked with a tiny spot of different colored paint. The researchers recorded the movements that the bees made
Von-frisch’s bee study: results
The bees made different movements depending on how far away the food source was from the hive. When the food was no further than 100 meters the bees did a dance by turning in rapid circles. When the food was moved further away, the bees performed a waggle dance. Von frisch found that the number of turns a bee makes in a 15 seconds waggle dancing is actually communication how far away the food source is.
Von frisch’s bee study: conclusion
Von Frisch concluded that bees use a variety of different movements to communicate to each other the distance and direction of food sources
Eval of Von-frisch
:) His research was some of the earliest into animal communication and encouraged others to carry out research in this area. A number of other researchers have replicated the study and found the same results. This increases the reliability.
:( Criticized as he overlooked the importance of sound. Other researchers have found that sometimes the bees do this dance in silence. When this a happens, other bees don’t follow. But when its done with sounds, then others will follow.
Body language
A general term to describe aspects of non-verbal communication
Eye contact
When two people in conversation are looking at each others eyes at the same time
