human language
A structured symbol system (words/gestures) used to convey meaning and express thoughts/emotions/ideas.
the hierarchical nature of language
Language is built in levels (phonemes → morphemes → words → phrases), with higher levels formed from lower ones.
what supports the universal need to use language
Evidence across cultures shows language is fundamental for social interaction and maintaining relationships.
psycholinguistics
Study of how language is processed in the mind (production, comprehension, acquisition).
the lexicon
Your mental dictionary of all known words.
semantics
The study of meaning in language.
lexical semantics
Meaning of words and how word meanings relate to each other.
word frequency
How often a word occurs in language.
the word frequency effect
High-frequency words are processed faster/more efficiently than low-frequency words.
what did Rayner & Duffy (1986) find about fixation duration
Reading time is influenced by word frequency; readers fixate longer on less common words.
speech segmentation
Identifying word boundaries in continuous speech.
why is speech segmentation hard (lack of silence)
Spoken language is continuous with few clear pauses between words.
lexical ambiguity
Words with multiple meanings.
lexical priming
Exposure to one word influences processing of related words.
what did Tanenhaus investigate (general)
How context affects speed of accessing meanings of ambiguous words during comprehension.
meaning dominance
The relative frequency/strength of a word’s meanings in memory.
biased dominance
One meaning is much more common/dominant than others.
balanced dominance
Two meanings are similarly common/dominant.
syntax
Rules/principles governing sentence structure.
parsing
Breaking a sentence into components to understand meaning.
the garden path model of parsing
People initially choose the simplest/most likely structure; if wrong, they must reanalyze.
heuristics
Mental shortcuts/rules of thumb that simplify decisions.
the visual world paradigm
Psycholinguistics method tracking eye movements while listening to sentences to reveal real-time processing/parsing.
what did Tanenhaus et al. (1995) show
Context influences online processing of ambiguous sentences (using eye tracking).
