Chapter 6 Flashcards
First words mark…
A transition from preverbal to verbal communication
Phonetically consistent forms (PCFs)
Describe the idiosyncratic wordlike productions children use consistently and meaningfully but that do not approximate adult forms
What is the age range of toddlerhood?
1-3 years old
Children who are beginning to transition from the prelinguistic stage to the one-word stage use ______
Referential gestures (gestures that indicate a precise referent and have a stable meaning across different contexts)
Deictic gestures
Gestures whose meanings change depending on the context (pointing, showing)
As children begin to transition to the two-word stage, they exhibit _______
Gesture-word combinations (pointing at mommy while saying her name)
Toddlers who use more gesture-speech combinations at 18 months demonstrate _______
Greater sentence complexity at 42 months of age
When children begin to use two-word utterances, they stop ______
Combining two referential gestures
Mirror neurons
Activate when people perform actions and when they observe other people perform actions (they’re a type of visuomotor neuron)
Theory of Mind
The ability to understand one’s own mental or emotional state, to understand that others also have mental or emotional states, and to realize that others’ mental and emotional states, beliefs, intentions, and perspectives differ from one’s own
False-belief tasks
Assess whether children demonstrate understanding that another’s beliefs can differ from one’s own beliefs
Customary age of production
Describes the age by which 50% of children can produce a given sound in multiple positions in words in an adultlike way
Age of mastery
The age by which most children produce a sound in an adultlike manner
Phonological processes
The systematic, rule-governed patterns that characterize toddler’s speech
Syllable structure changes
- Reduplication: repeating a syllable (wa-wa)
- Cluster reduction (“stong” instead of “strong”)
- Weak syllable deletion: deleting an unstressed syllable (banana - nana)
- Final consonant deletion: deleting the last consonant in a syllable (cat - ca)
Assimilation
- Consonant harmony: using consonants with like features in a word (doggie - doddie)
- Velar assimilation: producing a nonvelar consonant as a velar consonant (dog - gog)
- Nasal assimilation: producing a nonnasal sound as a nasal sound (candy - nanny)
Place-of-articulation changes
- Fronting: replacing a sound further back with a sound further forward (corn - dorn)
- Backing: replacing a sounds farther forward with a sound further back (daddy - gaggy)
Manner-of-articulation changes
- Stopping: replacing a fricative or affricate with a stop sound (jeep - deep)
- Gliding: replacing a liquid sound with a glide (love - wove)
Phonological perception involves:
Understanding that vocal characteristics of a speaker are not properties of the words themselves (when mom says water one way, and dad another way, the child will understand that both mean “water” and are referring to the same thing)
What age marks a transitional period in phonological development?
18 months of age
Novel nonneighbors
New words that are not phonologically similar to known words
