Neurogenic Communication Disorders & Cognition

What is the key distinguishing characteristic of the Arizona Articulation Proficiency Scale (AAPS) compared to other articulation tests?

It uses weighted values for phonemes based on their frequency of occurrence in American English speech.

What three main clinical advantages justify the use of basal and ceiling rules?

1. Saves testing time

2. Reduces client fatigue and loss of attention

3. Maintains standardized administration and test validity

What contributing factors should a clinician evaluate when investigating potential causes of a Speech Sound Disorder?

Hearing impairment, medical/neurological factors, dental problems, maturation and motor development, intelligence, sex, birth order, motivation, concern, and dialect.

Why does misarticulation of high-frequency consonants (e.g., /n, t, s, r, d, m/) exert a disproportionate impact on functional speech intelligibility?

Because these six sounds cumulatively make up almost 50% of all consonants spoken in conversational English, errors in these phonemes occur with high frequency.

Why is the scoring of the PPVT-5 classified as highly objective?

The client selects a picture from four clear choices, producing an unambiguous correct or incorrect response that requires no subjective rubric interpretation.

Why is the PPVT-5 particularly useful for non-readers and non-writers?

It requires no reading or writing; responses are indicated simply by pointing to one of four pictures or stating the picture number.

What are the standard mean and standard deviation parameters for standard scores in standardized language tests?

Mean = 100, Standard Deviation = 15.

What target population and age range are specified for the Goldman-Fristoe Test of Articulation 3 (GFTA-3)?

Individuals aged 2 to 21 years.

Why must clinicians supplement GFTA-3 standardized scores with converging diagnostic evidence?

Published peer-reviewed literature specifically analyzing GFTA-3 validity coefficients is sparse, and validity is compromised during non-standard administration (e.g., telehealth) or with dialectal variations.

What are key clinical strengths of the PPVT-5?

Easy administration, clear manual, objective scoring key, visual stimulus layout accessible to non-readers, training items to establish response mode, broad age span, and efficient basals and ceilings.

What are key clinical weaknesses of the PPVT-5?

Scoring can be complex/time-consuming, some picture items contain abstract geographic/physical concepts hard for young children to interpret, no instructive feedback is permitted, and it has questionable direct educational programming value.

How are etiological-categorical patterns identified during a language evaluation?

Through case history reviews, reports from interdisciplinary professionals, direct clinical observation, and medical records.

What is the expected normative Type-Token Ratio (TTR) range for typically developing children between 3 and 8 years of age?

A TTR between 0.45 and 0.50 (meaning approximately half of total words spoken are different words).

What is the primary diagnostic purpose of a speech screening?

To quickly differentiate individuals who communicate within normal limits from those who may have a communicative disorder and require a comprehensive evaluation.

What core behaviors should be analyzed during a connected speech sample?

1. Number and types of sound errors

2. Overall speech intelligibility

3. /vz/ (e.g., 'wolves')

4. /əz/ (e.g., 'dishes')

5. Irregular forms (e.g., 'feet')

What defines pragmatics in speech-language pathology?

The study of how language is used socially within communicative interactions.

Are separate normative scores provided to interpret the Fisher-Logemann Test of Articulation?

No; it provides developmental ages for single-phoneme consonants, as its primary intent is descriptive feature analysis.

Why must pragmatic language skills be evaluated across multiple communication environments?

Pragmatic behaviors are situationally and environmentally specific, so testing in a single structured clinical setting will not capture a complete picture of performance.

What specific terminology does the Fisher-Logemann Test of Articulation use to describe word positions?

Prevocalic, intervocalic, and postvocalic.

What are the mean and standard deviation parameters of the Stanine scoring scale?

Mean = 5, Standard Deviation = 2 (dividing performance into bands 1 through 9).

What does a substandard Type-Token Ratio (TTR) indicate clinically?

It indicates a lack of lexical diversity, serving as a primary quantitative marker for an expressive language delay or disorder.

Why is assessing stimulability critical for treatment planning and prognosis?

Erred behaviors that are easily stimulated indicate a favorable prognosis and serve as excellent, highly responsive starting targets in therapy.

What major diagnostic components must be included in a complete evaluation of Speech Sound Disorders (SSDs)?

1. Case history, interview, and reports from other professionals

2. Assessment of contributing factors

3. Screening and standardized articulation testing

4. Connected speech sampling

5. Stimulability testing

6. Error analysis (types, forms, consistency, intelligibility, rate, prosody)

7. Oral-facial examination

8. Hearing and language assessments

Why might single-word production accuracy on standardized articulation tests fail to reflect real-world performance?

Standard tests elicit phonemes in isolated single words, whereas conversational speech consists of complex, rapid, coarticulated movements where significantly more errors often occur.

What is the core emphasis of the Etiological-Categorical approach to language disorders?

Classifying language disorders according to underlying clinical medical categories or diagnostic conditions (e.g., CNS damage, Cognitive Impairment, sensory deficits, psychosis, Cerebral Palsy, seizure disorders).

How do normative studies of consonant acquisition from the 1970s compare to earlier studies from the 1930s?

Later studies indicate earlier developmental acquisition of consonants than the earlier 1930s studies.

What are two major limitations of relying on developmental norms for phonemes in clinical decision-making?

1. A norm represents an average age for a 'hypothetical child' that does not reflect individual variance.

2. Different normative research studies rarely agree on exact acquisition ages.

In phonology, how is phonological knowledge distinguished from phonological output?

Phonological knowledge is the underlying mental system of language, whereas phonological output is the actual spoken production of speech.

What testing protocol must an examiner follow if a client fails to establish a basal at the designated starting item?

The examiner must move backward sequentially to administer easier items until the required number of consecutive correct responses is achieved.

What sample activities assess conversational turn-taking during a pragmatic assessment?

Alternately counting or reciting the alphabet (examiner says 'a', child says 'b'), or taking turns reciting 1-2 lines of a familiar story.

What three parameters define language content, form, and use?

1. Form: Structural rules (syntax, morphology, phonology)

2. Content: Meaning system (semantics)

3. Use: Social communicative rules (pragmatics)

What is the specific utility of a Growth Scale Value (GSV) in standardized assessment?

It uses an equal-interval scale to track an individual's longitudinal development and progress over time across test administrations.

What defines a phonological process disorder?

A speech sound disorder where a child consistently uses rule-based simplification patterns to simplify adult speech that are normal in early development but persist beyond the expected age.

Which precise physiological actions must occur simultaneously with motor sequencing, timing, direction, force, and placement to achieve normal speech articulation?

1. Airstream alteration

2. Initiation and halting of phonation

3. Velopharyngeal (VP) action

What four traditional categories define phonetic error types (SODA)?

Substitutions, Omissions, Distortions, and Additions.

In speech elicitation, how do spontaneous and imitative responses compare across age groups?

Spontaneous picture naming is preferred for older children, but spontaneous and imitative methods yield equivalent results in young children up to age 6.

What three descriptive dimensions are used to classify consonant phonemes?

Place of articulation, manner of articulation, and voicing.

What specific language construct is assessed by the Peabody Picture Vocabulary Test, Fifth Edition (PPVT-5)?

Single-word receptive lexical knowledge (receptive vocabulary acquisition).

How does the Developmental-Descriptive approach to language assessment differ from the Etiological-Categorical approach?

It details the client's specific strengths and deficits in linguistic form, content, and use relative to typical development, rather than categorizing them by medical etiology.

What administration time and age range are specified for the PPVT-5?

Administration takes 11 to 12 minutes across an age range of 2.5 to 90+ years.

What are the exact basal and ceiling criteria for administering the PPVT-5?

Basal: 3 consecutive correct responses from the entry point. Ceiling: 6 consecutive incorrect responses.

What visual stimulus format and structural organization are unique to the Photo Articulation Test (PAT)?

It uses actual photographs instead of line drawings, and its scoring sheet and stimuli are organized strictly by place of articulation (lip sounds, tongue sounds, vowels).

What is the primary difference between organic and functional etiologies of speech sound disorders?

Organic etiologies stem from an identifiable physical, structural, or neurological cause, whereas functional etiologies have no precise or identifiable physical cause.

Can an articulation test predict whether a young child's sound errors will spontaneously correct over time?

No; articulation tests provide an inventory of sampled speech sounds at a given moment, but they are not predictive of spontaneous recovery.

In school-age children with Developmental Language Disorder (DLD), what expressive narrative and discourse deficits are commonly observed?

Difficulty creating and understanding narratives, answering inferential questions, omitting critical details in discourse, struggling with expository text, and failing to comprehend cause-effect relationships.

What are the typical operational constraints of a speech screening?

It should take no more than a few minutes, does not require a formal standardized battery, and yields a binary pass/fail decision (adequate vs. inadequate).

What are the inflectional past tense allomorphs evaluated in English morphological feature analysis?

1. /d/ (e.g., 'spilled')

2. /t/ (e.g., 'dropped')

3. /əd/ (e.g., 'melted')

4. Irregular forms (e.g., 'broke')

1. Substitution: /pɛn/ for /tɛn/

2. Omission: /αp/ for /stαp/

3. Distortion: /maʊʃ/ for /maʊs/

4. Addition: /bəlæk/ for /blæk/

What clinical levels and response types does the GFTA-3 evaluate?

Spontaneous and imitative consonant productions at both the single-word and connected sentence levels, as well as stimulability.

How does the Arizona Articulation Proficiency Scale (AAPS) establish its normative age criteria for sound mastery?

It uses the age at which 90% of the normative sample correctly produced the sound, rather than average performance.

On a standardized normal distribution bell curve, how do Standard Scores, Z-Scores, Percentile Ranks, and Stanines align relative to the mean?

The mean corresponds to a Standard Score of 100, Z-Score of 0, 50th percentile rank, and Stanine of 5, with standard deviations shifting scores by 15-point increments.

What are the five core clinical purposes of conducting an assessment of articulation and phonological processes?

1. Describe articulatory/phonological status

2. Determine if speech deviates sufficiently to warrant intervention

3. Identify contributing factors

4. Make prognostic judgments

5. Monitor changes over time

What structured sampling activity can a clinician use to evaluate a child's ability to make requests?

Ask the child to draw a circle without providing a pencil, or present a hypothetical scenario regarding asking for an item.

In psychometrics, how is a raw score defined and converted?

A raw score is the initial unadjusted count of correct responses; it holds minimal clinical meaning until converted into a normative score.

What is a major clinical shortcoming of the Arizona Articulation Proficiency Scale (AAPS) scoring system?

Omission, substitution, and distortion errors are all treated and weighted in the exact same manner.

What is the main clinical advantage of using a Distinctive Feature approach in speech therapy?

Targeting a missing distinctive feature in treatment can remediate multiple sound errors simultaneously across phonemes that share that feature.

What does a percentile rank of 25 indicate regarding a client's performance?

The client scored equal to or higher than 25% of the individuals in the standardized normative sample.

How many items are contained in the diagnostic subtest versus the screening subtest of the Templin-Darley Tests of Articulation?

141 items in the diagnostic test and 50 items in the screening test.

Which six English consonants account for nearly half of all consonant occurrences in continuous speech?

The consonants /n, t, s, r, d, m/.

What steps are required to calculate scores on the GFTA-3?

1. Sum total raw score

2. Convert raw score to standard score using normative tables

3. Determine confidence intervals, percentile ranks, test-age equivalents, and Growth Scale Values

How does the Fisher-Logemann Test of Articulation differ fundamentally from standard articulation tests in its error analysis?

It categorizes and records error sounds according to feature classifications (voicing, manner, place) rather than simply marking error occurrences.

Which word positions are evaluated across most standardized articulation tests?

Initial, medial, and final positions.

What four modalities must be evaluated when assessing comprehensive language skills?

1. Listening comprehension

2. Reading comprehension

3. Spoken expression

2. Khan-Lewis Phonological Analysis

3. Clinical Assessment of Articulation & Phonology 2 (CAAP-2)

What is the definition of stimulability in a speech sound evaluation?

The client's ability to produce a correct or improved production of an erred sound when attempting to imitate the clinician after receiving cues.

What is a ceiling in standardized testing, and what occurs when it is reached?

The stopping point reached when an examinee makes a specified number of consecutive incorrect responses; subtest administration ends immediately.

What defines the phonological process of alveolarization?

The substitution of an alveolar phoneme for a labial or linguadental phoneme (e.g., producing 'tan' for 'pan').

What pragmatic skills are evaluated when a child is asked to explain the steps involved in making a bed or preparing a meal?

Action sequencing and procedural discourse.

What does the Type-Token Ratio (TTR) measure during language sample analysis?

It measures functional vocabulary skills and lexical diversity in a language sample.

What is a basal in standardized testing, and how is it operationalized?

The starting floor level where an examinee correctly answers a specified number of consecutive items in a row.

What is the primary methodological limitation of relying solely on connected speech samples to evaluate articulation?

Identification of specific sound errors is difficult because not all English phonemes are guaranteed to be naturally elicited during spontaneous conversation.

On the PPVT-5, what standardized prompt must an examiner deliver if the client fails to respond within 10 seconds?

The examiner prompts the client by saying, 'Try one.'
