LANGUAGE RESEARCH IN SERVICE TO THE NATION
Unique UARC Mission/Role
CASL is charged to deliver independent, empirically-based research solutions that:• Improve the human-centric components of military and intelligence
operations that include language performance, analysis and culture• Underpin leadership decisions on language readiness for the
warfighter and the intelligence analysts who support them• Elevate language to the stature of math and science as an IC & DoD
core capability
CASL is the only University Affiliated Research Center devoted to the study of language

Presentation Structure
• Predicting Language Success and Diagnosing Individual Differences:– Executive Function– Hi-LAB: Cognitive predictors of high level language
aptitude– ALAB: Applications to assessing aptitude for learning

Predicting Language Success
LANGUAGE RESEARCH IN SERVICE TO THE NATION
A Causal Model of Language Proficiency
Cognitive and perceptual components associated with language aptitude and proficiency
the working memory system
21
LANGUAGE RESEARCH IN SERVICE TO THE NATION
Executive Function: Working Memory• Active information storage that allows
attention to be focused for the purpose of higher level combination, reasoning, or other subsequent processing.
• Decays quickly
• Varies among individuals
• Affects language processing (e.g. error recovery)

Linguistic Tests
• ALAB has two linguistic tests: Language Analysis and Words in Sentences
• In addition to the ALAB instructions, language and cultural concepts must be adapted and translated.
• Language Analysis: required transliteration of an artificial language from Roman to Arabic
• Direct assessment of linguistic ability

Example: Language Analysis Test• Word list:

fMRI activation: PreTraining
40
Pre-training brain activation in the high memory load condition for the vsWM and the placebo control group. Panel A shows the vsWM group, and panel B shows the placebo control group. Panel C shows the β values for the right and left IPL.
No difference in activation prior to training
LANGUAGE RESEARCH IN SERVICE TO THE NATION
fMRI activation: PostTraining
41
Less diffuse activation following working memory training
Post-training minus pre-training BOLD brain activation in the high memory load condition for the vsWM and the placebo control group. Panel A shows the Post-Pre for the vsWM group, and panel B shows the Post-Pre for the placebo control group. Panel C shows Placebo control minus the vsWM Post-Pre. Panel D shows the β values for the right and left IPL.

Aptitude-by-Treatment Interaction
Problem
Individuals who are already selected for intelligence and motivation and have attained functional ability need to acquire higher levels of language
Solution
Match cognitive aptitude profile to language training procedures to optimize training and boost outcome levels
