Chapter 4 Flashcards
What is interesting about, for example, white-handed gibbons? How is it simple compared to humans thoug?
They have sophisticated calls for social relations and to warn of predators. Humans have a huge vocabulary and a grammar.
According to Aitchison, how many fathers of language are there?
Eleven.
What are some of Aitchison’s features of language?
Vocal-auditory channel, arbitrary (different languages have different symbols), semanticity (able to generalize to all members of a group), spontaneous usage, turn-taking, duality(sounds only have meaning in combination), cultural transmission (only learn if brought up with language), displacement (refer to things not in the here and now). Unique to humans: structure-dependence, creativity, ability to mind-read.
What is structure dependence?
We don’t just put words in any order but there is an underlying structure.
What can we say about the creativity of sentences?
Many sentences in human language are completely novel…colorless green ideas sleep furiously.
To what extent can non-human animals mind-read?
Chimpanzees show some ability e.g. To help get an out-of-reach object.
While chimpanzees demonstrate individual intentionality, what are they not good at?
Shared intentionality or joint goals. Unlike human infants, chimps take no pleasure in non-instrumental, social activities (we-intentionality).
For Tomasello, what is the basis of human communication?
Intention-sharing, co-operative motives, shared understandings, we-intentionality.
What are concepts?
Mental categories.
What can we say about the relation of properties to concepts?
Certain properties define a concept.
What is the classical view of concepts and properties?
That if something has all the properties of a concept then it must be an equally good exemplar.
Which theory challenged the classical view of concepts?
Prototype theory.
To test prototype theory, what did Eleanor Rosch ask participants to do?
Asked participants to rate how good of an example different fruits were e.g. Olive versus an apple. Some members of a category were judged to be better examples than others.
What was a problem with the design of the original Rosch experiment? How did she overcome this?
How ‘good’ an example…‘good’ can mean different things. She overcame this by doing the experiment again and asking how good and how typical and found there was no correlation between the two. Therefore original results not because they interpreted good as enjoyable.
How was frequency a problem in the original Rosch experiment?
E.g. Apple is more typical than olive because it is more common. This potentially confounding variable was ruled out by Mervis.
How are confounding variables ruled out in psycholinguistic experiments these days?
Match word length and frequency.
Observing typicality effects in experiments without confounding variables suggests what?
That typicality effects are real.
How do children learn learn words for category members?
In order of typicality, suggesting that typicality is a genuine and real psychological phenomenon.
What did Rosch and Mervis show about by certain members of a category are more typical and other members?
Share more properties with other members of the category and fewer properties with other members.
What is a prototype?
The best example of a category. All the properties of its category and none of another category.
Why is using artificial stimuli (strings) to test typicality effects useful?
Provides more evidence and rules out confounding variables such as word frequency.
What is another factor which has a correlation with typicality effects?
The extent to which an object fulfills its main function.
Kurbat et al used shapes rather than words to test typicality effects. What did they find? What does this show?
How typical shapes are determines typicality. This shows that it is not just words but concepts too.
What have studies into individual differences in typicality effects shown?
E.g Brits versus Americans have different ideas about what a prototypical boot is.
People often change their minds about whether or not a borderline case (e.g. Olive) belongs to a category.
A lot of variation in properties PPS listed.
Prototype theory suggests fixed what?
Concepts and properties.
