Language Flashcards
Criteria of Natural Language
Regular, Arbitrary, Productive
Regular
governed by rules and grammar. A sentence can be reorganized and still retain its meaning because a system of rules determines how each word fits with the ones around it.
Arbitrary
the lack of resemblance between words and their meaning.
Productive
there are almost limitless ways to combine words to describe objects, situations and actions.
Whorf-Sapir Hypothesis
suggests that language has the power to influence our thoughts and perceptions
Evidence supporting Whorf-Sapir hypothesis
The Piraha only had three counting words, and had difficulty with fine numerical concepts
Evidence against Whorf-Sapir Hypothesis
Cultures that lack specific words to differentiate between relatives are still able to understand the difference between each relative.
Morphemes
the smallest unit of sound (or signs other than sounds) the contains information. Often a word, but some words contain multiples.
Phoneme
the consistent sounds that make up a morpheme. Vary across languages - some combos are not valid in one language but are in another. The rules can be used to create plausible words that have no meaning.
Syntax
the rules that govern how sentences are put together. Also known as grammar. Differences in rules are as various as the languages they come from.
Semantics
refers to the meaning of each individual word. A sentence may have perfect syntactics but no semantic meaning.
Language development
Milestones in language rapidly increase from cooing at 12 weeks, to babbling at 1 year to an 850+ word vocabulary at 2.5 years.
Babbling
drawn out sounds made of a variety of combinations of vowels and consonants. The use of inflection and rhythm may sound like a real sentence. Combinations progress to become real words.
Language Explosion
vocab increases rapidly and have mastered the major concepts of language. This improves in complexity throughout childhood.
The Segmentation Problem
differences in languages lead to a difficulty in understanding the meaning of the word. It’s the difficulty you have separating the speech stream into word units. Early speech segmentation skills show a strong positive correlation with expressive vocabulary.
Universal Phoneme Sensitivity
the ability of infants to discriminate between any sounds they’re tested on, including sounds from non-native languages. The idea that adults can’t do this as well suggests that there must be some developmental basis for this.
Head-Turn Procedure
method of testing phoneme sensitivity in infants. positive reinforcement when he turns his head towards a new sound; if he remains neutral until a new phoneme sound is introduced, then he can discriminate.
Hindi Experiment
A method of comparing phonemic sensitivity between infants and adults. Discriminative abilities between exclusively Hindi phonemes –> adult english performed most poorly, english infants performed almost as well as Hindi adults.
Disappearance of universal phoneme sensitivity in infants
developmental pattern - by the end of the first year, infants have already lost most of their discriminative abilities
Implications of Varying Degrees of Phonemic Sensitivity when Learning a Novel Language
exposure to a language over 10 months will improve ability to speak and understand, but more time and practice is needed to discriminate fine phonemic contrasts. Learning another language at a younger age leads to superior mastery
Social Learning Theory
the theory that children learn though imitation and operant conditioning. Supported by children that have not been exposed to language throughout their childhood and cannot speak.
Evidence against Social Learning
development is too rapid and complex to be learned by imitation and reinforcement alone. They combine words in novel ways that were neither modelled nor reinforced.
Overextensions
apply a rule too broadly. (EX: uses doggie to mean any four legged animal) (EX: adding suffix ‘ed’ in inappropriate circumstances)
Underextensions
apply a rule to a specific object only. (EX: doggie is only for her dog an no other dog)
