minimal pair contrast therapy
answer
the therapeutic use of pairs of words that differ by only one phoneme
question
types of minimal pair contrast therapy
answer
minimal opposition contrast therapy, maximal oppositions approach, multiple oppositions approach
question
minimal opposition contrast therapy
answer
a method in which minimal pairs are employed as the beginning unit of therapy (sounds differ in only 1 or 2 production features)
question
when to use minimal opposition contrast therapy
answer
errors of phonemic substitutions, client is stimulable for the target sound
question
minimal opposition contrast therapy target selection
answer
phonemic substitutions/place, manner, voicing features/ select the least number of differences/ child's age and developmental level/ intelligibility/ stimulable sounds have priority
question
minimal opposition contrast therapy steps
answer
1. familiarize client with minimal pair 2. discrimination testing (child points, 7 consecutive correct response required) 3. production training (reversal of roles is needed-may be breakdown) 4. carryover training ex. a + word (to more complex carrier phrases/opportunity for repair)
question
maximal opposition approach
answer
minimal pairs are beginning unit of therapy, but chooses sounds that are produced very differently
question
maximal opposition approach when to use
answer
at least 6 sounds missing from inventory (moderate to severe disorder)
question
maximal opposition approach target selection
answer
2 sounds-not in inventory/ maximal differences in distinctive features-number and nature of features
question
major class features=maximum feature distinction (maximal opposition approach)
answer
vocalic, consonantal, sonorant
question
vocalic
answer
differentiate vowels/liquids from stops/fricatives/affricates/nasals
question
consonantal
answer
differentiate stops/fricatives/nasals/liquids from glides/h
question
sonorant
answer
differentiate nasals/liquids/h from stops/fricatives/affricates
question
maximal opposition approach examples
answer
leg-keg, lane-cane, lamp-camp, lee-key
question
phases of maximal opposition approach
answer
imitation phase-75% accuracy over 2-7 consecutive sessions, spontaneous phase-90% accuracy with no model for 3-12 consecutive sessions
question
multiple opposition approach
answer
alternative approach to contrastive minimal pairs
question
when to use multiple opposition approach
answer
severe speech disorder, at least 6 sounds missing from inventory across 3 manner categories, one phoneme used for several phonemes (homonymy)
question
target selection multiple opposition approach
answer
maximal distinctions, maximal classifications; greatest impact
question
examples of multiple opposition approach
answer
/d/ substituted for /g/, voiceless 'th', 'sh', 'j'
question
multiple opposition approach therapy options
answer
use minimal contrast therapy or specific treatment
question
multiple opposition approach specific treatment
answer
1. imitative level-70% accuracy, 2 consecutive sessions/ 2. spontaneous phase-90% accuracy, 2 consecutive sessions/ 3. generalization-90% accuracy of target sounds in untrained words/ 4. conversation-based phase-naturalistic
question
around _____ minimal pairs is best
