Attention & Language Flashcards
Selective Attention
- focusing on one part of the sensorium while ignoring other stimuli
- acts as a filter between sensory stimuli and our processing systems
Cocktail Party Phenomenon
phenomenon of being able to focus one’s auditory attention on a particular stimulus while filtering out a range of other stimuli
Divided Attention
ability to perform multiple tasks at the same time
New or complex tasks require undivided attention and utilize ____ _____
controlled (effortful) processing
Familiar or routine actions can be performed with ____ _____
autonomic processing (permits the brain to focus on other tasks with divided attention)
What are the 5 basic components of language?
- phonology
- morphology
- semantics
- syntax
- pragmatics
Phonology
- refers to the actual sound of language
- there are about 40 phonemes in english
Morphology
- refers to the structure of words
- many words are composed of multiple building blocks called morphemes, each of which connotes a particular meaning
Semantics
refers to the association of meaning with a word
Syntax
refers to how words are put together to form sentences
Pragmatics
- refers to the dependence of language on context and pre-existing knowledge
- manner in which we speak may differ depending on the audience and our relationship to that audience
Prosody
- the rhythm, cadence and inflection of our voices
- affects pragmatics
Language acquisition at 9 - 12 months:
babbling
Language acquisition at 12 - 18 months:
about one word per month
Language acquisition at 18 - 20 months:
“explosion of language” and combining of words
Language acquisition at 2 - 3 years:
longer sentences (3 words or more)
Language acquisition at 5 years:
language rules largely mastered
Errors of Growth
- occurs around 3 years of age when the child creates longer sentences but these sentences have a lot of grammatical errors
- child applies a grammatical rule in a situation where it does not apply
Nativist (Biological) Theory of Language
- largely credited to Noam Chomsky
- advocates for existence of some innate capacity for language
- human’s innate ability to produce language is called the language acquisition device (LAD) which is a theoretical pathway in the brain that allows infants to process and absorb language rules
- belief in a critical period (btw 2 years and puberty) for language acquisition
Sensitive Period
- time when environmental input has maximal effect on the development of an ability
- for language development this period exists before the onset of puberty
Learning (Behaviorist) Theory of Language
- proposed by B.F. Skinner
- explained language acquisition by operant conditioning
- parents reinforce sounds that sound most like native language of parents leading to infants perception that sounds that are not reinforced are of little value and are not part of parent language
- theory does not explain the explosion of vocabulary that occurs in early childhood
Social Interactionist Theory of Language
- focuses on the interplay between biological and social processes
- language acquisition is driven by child’s desire to communicate and behave in a social manner
- reinforcement of certain brain circuits as child interacts with others while other circuits are de-emphasized and atrophy
Whorfian Hypothesis (Linguistic Relativity Hypothesis)
- our perception of reality is determined by the content of language
- language affects the way we think rather than the other way around
- Ex. Inuit language has many names for different types of snow meaning that Inuits are better at discriminating subtleties between different types of snow compared to the English
What are the main brain areas involved in language?
- Broca’s area
- Wernicke’s area
- Arcuate fasciculus
