Differences in iq and Memory of Monolingual/Bilingual Children who Suffered a tbi

 
Hypotheses 
1. It is hypothesized that bilingual children who have had a traumatic brain injury 
will have significantly lower VIQ’s compared to their own PIQ’s when 
controlling for age of language acquisition and age when TBI was obtained. 
2. It is hypothesized that bilingual children who had a traumatic brain injury will 
have greater splits between their VIQ and PIQ’s (with PIQ being the higher value) 
compared to monolingual children who have incurred a traumatic brain injury 
when controlling for age of language acquisition and age when TBI was obtained.

3. It is hypothesized that bilingual children who have had a traumatic brain injury 
will have a significant discrepancy (> 1SD) between their verbal and nonverbal 
memory scores (with verbal having a lower standard score) when controlling for 
age of language acquisition and age when TBI was obtained.

CHAPTER TWO 
METHODS 
 
Participants 
The targeted study population consists of monolingual and bilingual children who 
have incurred a moderate to severe TBI. The sample was recruited from the Loma Linda 
University Children’s Hospital Level-1 Trauma Center’s emergency department. The 
data utilized in this study is archival data from an NIH funded grant # 5 RO1 NS 054001-
02 that was approved at the Loma Linda University Children’s Hospital (Ashwal, 2005).
