1. In Shaywitz's research, which brain reading pathway is UNDERACTIVATED in readers with dyslexia during word recognition tasks?
Shaywitz's neuroimaging studies show underactivation of the left occipito-temporal region (the 'word form area' or 'brain's letterbox') in dyslexic readers.
2. Which of the following background history factors is most relevant to include in a dyslexia assessment intake?
Dyslexia has a strong genetic component, and a family history of reading difficulties is a significant risk factor to document.
3. Which of the following assessment domains is NOT typically included in a comprehensive dyslexia evaluation?
While co-occurring motor issues may be noted, gross motor coordination is not a core domain assessed in a standard dyslexia evaluation.
4. Onset-rime awareness involves:
Onset-rime awareness involves recognizing that syllables can be split into the onset (initial consonant or cluster) and the rime (the vowel and everything after it, e.g., 'c' + 'at' in 'cat').
5. A CDT working in a private practice setting should store physical student files in what manner?
Physical records must be stored in a locked, secure location with access restricted to authorized personnel to protect student confidentiality.
6. Which practice best supports both infection control and a welcoming therapy environment for students with dyslexia?
A visible, consistent cleaning routine maintains safety without making the environment feel clinical or unwelcoming to students.
