Norms
Criterion references batter of tests
Norms on people with aphasia & non-brain damaged subjects
Nonword Minimal Pairs
Auditory Processing
Listen to 2 non words, are they the same/different?
e.g. zog/zeg, zog/zog
Tests AAS
Discrimination using Word Minimal Pairs
Auditory Processing
Listen to 2 words & say if they are same/different
If they do well on this task, but do NOT do well on nonword minimal pairs, this implies they’re relying on their SS to make judgments, therefore, AIL will be impaired
Helps determine how much semantic/lexical info is contributing to auditory processing abilities
Tests AAS
Minimal Pair Discrimination Requiring Written Word Selection
Auditory Processing
Pt shown two words “Pill Bill” and clinian reads a word. Pt has to circle which one clinician says
Tests VAS
Discrimination of words can use lexical processes (and semantic processes)
Compare to non word task to look at the pts reliance on lexical contexts for phonemic perception
Minimal Pair Discrimination Using Picture Selection
Auditory Processing
Requires pt to match single heart word with corresponding picture from choice of 3 pictures which are phonologically related
FO3, Say Word, Point to pic that means it (goat, boat, coat)
Tests AAS & SS
If pt has impairment at PIL, the picture distractors will increase likelihood of phoneme errors
Imageability & Frequency Auditory Lexical Decision
Auditory Processing
Pt listens to words & non words, judge if word is real or not
Looks at effect of imageability & frequency in deciding whether or not something is a word
Significant effect on imageability in auditory lexical decision, implies that the pt is using SS on which to base a decision
Tests AIL
Auditory Lexical Decision & Morphology
Auditory Processing
pt says whether word is real or not (e.g. “Happiness” vs. “Happiment”)
If pt makes false + errors, it suggests they can’t judge whether they are legal pairings or not; if morpho errors are also made in Visual Lexical Decision it suggests semantic locus for difficulty, or even an output locus)
If makes morpho errors when tasks presented auditory by NOT visually, it suggests there is a problem at PIL
Tests AIL & morphology
Syllable Length Repetition
Auditory Processing
Looks at effect of syllable length on auditory word repetition (of real words)
Pt who have more difficulty in longer words may have problem at POB or below
If there is trouble at POB, may result in phonol forms that are not real words
Tests AAS–>PL
Non word Repetition
Auditory Processing
Tests integrity of sublexical acoustic-phonological conversion
Tests AAS–>PL
if they have difficulty with longer lengths, output locus may be suspected
Imageability & Frequency Repetition
Auditory Processing
words and nonwords, looks for imageability and frequency effects in auditory repetition
imageability effect in repetition with semantic errors suggests that repetition is taking place via SS
Grammatical Class Repetition
Auditory Processing
Repetition of grammatical word classes N, Adj, V, functors
looks for effect of grammatical word class in repetition
if pt has problem in repeating functors (and perhaps verbs) suggests pt using semantic-syntactic system to repeat
Lexical Morphology & Repetition
Auditory Processing
Looks at if repetition is effected by morphological complexity
Includes controls to rule out morphological vs. phonological (e.g. “orchard” vs “tortured”)
Sentence Repetition
Auditory Processing
Ability to repeat sentences aloud
Examines to which extent syntactic & semantic variables influence the pts ability to process/produce a meaningful and syntactically coherent string of words
Auditory Digit Span
Tests Phonological STM , PL
Selective deficit of repetition span may reflect an impairment of phonol output buffer
YET: auditory repetition may involve input processing deficit; however, deficit may rather reflect impairment of an output buffer
Rhyme Judgment Requiring Picture Judgment
Auditory Processing
Assesses whether pt can select pic whose name rhymes with a given stimulus picture
Requires pt to first retrieve pic names for phonol output lexicon
Tests Pic input –> SOL
Word Rhyme Judgment
Auditory Processing
Tests integrity of phonol STM storage, attentional abilities, input processing abilities, segmentation skills
Pt hears 2 words and needs to say if they rhyme or not OR they see 2 written words and say whether they rhyme or not
Phonological Segmentation of Initial Sounds
Auditory Processing
listen to monosyllabic word, segment initial sound, point to letter that is the initial sound
requires PGC
tests AAS independent of lexical and phonoloigc processes
Phonological Segmentation of Final Sounds
Auditory Processing
listen to word, segment final sound, point to letter that is the final sound
need PGC
AAS independent of phonological and lexical processes
Letter Discrimination - Mirror Reversal
Reading & Spelling
must distinguish between correct form and mirror-reversed form of individual wrritten letters
they need to cricle the wrong way letters
difficult for those with deficits in written letter identification
Tests VAS
Uppercase/Lowercase Letter Matching
Reading & Spelling
find the correct lower case form to match a given upper case form
distractor letters visually similar to target
don’t need to NAME the letter, just have to MARK it
Tests VAS
Lower to Uppercase Letter Matching
Reading & Spelling
must find correct upper case form to match a given lower case form
distractor letters visually similar to target
do not have to NAME the letter, just have to MARK it
Tests VAS
Letter Discrimination: Words & Non Words
Reading & Spelling
Examines whether pt can match upper and lower case letters in multi-letter strings
has to decide if pairs are same/different
e.g. bribe - BRIBE
Decisions to non words pairs not helped my lexical information
Decisions to word pairs can be based on lexical knowledge (if they do well on real words, they’ve determined its a word, but not meaning yet)
Tests VAS (more complex)
Letter Naming & Sounding
Reading & Spelling
Name AND sound the letters of the alphabet
People with dyslexia have difficult time with this task
Test GPC
Spoken Letter Written Letter Matching
Reading & Spelling
Match heard letter or letter sound with its appropriate written form
Have to be able to identify written letters and process the heard letter aurally and match it with the written form
Choose from FO4 (w/distractors)
Tests GPC
Visual Lexical Decision Legality
Reading & Spelling
Letter combinations with illegal combinations, mark the words that are real words
Can use orthotactic or phonotactic properties to make decisions about words
Tests VIL
