How to choose which aptitudes and treatments to investigate?

• Client needs – Selection – Training options • Information about the participants – Target measures that differ most – Focus on measures that will impact operational language use in the field • Information from science – Research-based training techniques – Measures that get closer to “ground truth” – Stronger predictions for real-world performance, beyond the lab

From Hi-LAB to ATI

• High-Level Language Aptitude Battery (Hi-LAB) test to document cognitive strengths and challenges – Aptitude Profile Card • Structuring to improve learning conditions (Immersion, online, classroom)
