The Sapir-Whorf hypothesis suggests that thinking depends on language.
Humans have a unique ability to use language to communicate, which is different from the communication abilities of animals.
There are different theories that attempt to explain the relationship between language and thought, including Piaget’s theory that language depends on thought and the Sapir-Whorf hypothesis.
According to Piaget’s theory, children will develop language in four stages: the sensorimotor stage, the pre-operational stage, the concrete operational stage, and the formal operational stage.
In the sensorimotor stage, babies are discovering what their bodies can do, including the ability to make sounds.
Babies then learn to copy the sounds they hear other people making in the pre-operational stage.
During the concrete operational stage, the ability to use language has developed significantly however children use it to talk about actual concrete things.
Once children reach the formal operational stage, they can use language to talk about abstract, theoretical ideas.
Piaget believed that while all children move through these stages, some people do not get to the formal operational stage.
Two properties unique to human language and communication are productivity and displacement.
Karl Von Frisch’s bee study from 1950 is important as it was one of the primary studies into animal communication and influenced other researchers to conduct research into animal communication.
The results from Karl Von Frisch’s bee study have been found to be reliable as when others have recreated it, they have found similar results.
The artificial setup of sugar-water and bees having to gather this from glass containers is not natural or indicative of the everyday behaviour of bees.
The functions of eye contact include regulating flow of conversation, signalling attraction and expressing emotion.
Bees do not normally live in such hives and this may have affected their behaviour.
Researchers found that bees may also use cognitive maps based on their memory of landmarks.
Human communication and animal communication may share some similar properties, but only human communication contains all properties.
Body language includes open and closed posture, postural echo and touch.
Non-verbal communication can be simply defined as a way of conveying messages without the use of words.
Personal space includes cultural, status and gender differences.
More is being learnt about animal communication all the time.
Communication that uses words is called verbal communication.
Researchers found that putting a sugar solution on flowers also resulted in the bees acting the same way as in the study, indicating the setup is valid and can be generalised to real-world settings for bee behaviour.
Displacement is the ability to communicate about things that are not present or events that have yet to happen in the future.
Due to the artificial setup of Karl Von Frisch’s bee study, it could be argued to lack ecological validity.
Productivity is the ability to create an unlimited number of different messages.
It is difficult to say for certain which properties of language are design features used exclusively by humans as we do not fully understand animal communication.
Another limitation of Karl Von Frisch’s bee study is the use of glass hives.
Piaget created his theory based on the observation of his own children, which may have affected the validity of his findings.
Women tend to have their personal space boundary invaded more often by men than the other way around.
Eye contact is used to regulate the smooth flow of conversation and can express emotion.
Pupil dilation expresses emotion and can influence attraction.
Personal space is affected by age and personality, with people tending to sit or stand next to people if they are a smaller age and people with the personality types known as introverts having a larger personal space boundary than those deemed extroverts.
People have a preference to those that look at them more frequently, which may be a signal for attraction.
Touch is a powerful signal that can produce unconscious emotional reactions and can lead to people being favoured more positively.
Women prefer to sit next to their friends by their side while men prefer to sit opposite them.
Status is another factor that affects personal space, with people tending to stand closer to others they deem to be of the same status as themselves compared to people of a higher status.
The posture someone adopts influences how much they are liked.
There are gender differences in personal space, with men having a bigger personal space boundary than women and both genders preferring to have a greater amount of space between themselves and members of the opposite sex.
Cultural norms are another factor that affects personal space.
