Final answer:
False. Clinicians on the Arizona-4 need to compare the Total Scores for Word Articulation and Sentence Articulation to determine significant differences.
Step-by-step explanation:
False. Clinicians on the Arizona-4 need to pay attention to the difference between the Total Scores for Word Articulation and Sentence Articulation to determine if there is a significant difference, not a critical difference.
During a speech assessment using the Arizona-4, clinicians assess the clarity of a person's speech by measuring their ability to articulate individual words and complete sentences. The Total Scores for Word Articulation and Sentence Articulation are calculated based on the number of errors made during the assessment. By comparing these scores, clinicians can determine if there is a significant difference in the person's ability to articulate words versus sentences.
For example, if a person's Total Score for Word Articulation is significantly lower than their Total Score for Sentence Articulation, it indicates that they may have difficulty with specific sounds or phonemes. This information can help clinicians tailor their intervention strategies to target areas of weakness and improve the person's overall articulation skills.
