Chapter 9 - Language And Thinking Flashcards
Psycholinguistics
• The scientific study of the psychological aspects of
language
Grammar
• The set of rules that dictate how symbols can be
combined to create meaningful units of communication
Semantics
Meaning of words
Generatively
Combine symbols to generate an infinite number of
messages that can have novel meaning
Displacement
• Can communicate about events and objects not physically present
• Past, future, imaginary events, can be symbolically
represented
Surface structure
Consists of ways symbols are combined
- syntax
Syntax
Rules for combinations (grammar)
Deep structure
Underlying meaning of combined symbols
- semantics
Semantics
Rules for connecting the symbols
Phonemes
- Smallest units of sound recognized as separate • Do not correspond to letters of alphabet • Humans can produce 100s of phonemes
- No language uses all
Morphemes
• Smallest units of meaning • Combination of phonemes
Syntax
Syntax determines how phonemes combine into
morphemes
• Some are single letters (s, ed)
• Some are single syllable words (hat, bat)
What’s the order of language structure
Phonemes - morphemes - words - phrases - sentences
The role of bottom-up processing
Individual elements of a stimulus are analyzed and
then combined to form a unified perception
The role of top-down processing
• Sensory information is interpreted in light of existing
knowledge, concepts, ideas, and expectations
- speech segmentation
Speech segmentation
Perceiving where each word within a spoken sentence
begins
Bro as area
Speech formation, overlap with primary motor cortex, associated with hand movements and language
Wernickes area
Speech understanding
Damage to either the wernickes area or Broca’s area can result in
Aphasia: permenant / temporary damage to perception of language
Sex differences in the brain
Neural systems seem to show differences in males and females
MALES: activation in left hemisphere, more aphasia symptoms
FEMALES: activation of both hemispheres, less symptoms
Infants (1-3 months) learn to
Vocalize entire range of phenomes
6-12 months age:
discriminate sounds specific to
native language
Language acquisition device (LAD)
All languages would have nouns or verbs and rules that are applied to them. Every language is different. Switches are turned on or off for each language. Calibrating your brain to learn the language.
