Processing words in the real world: A protocol for investigating the dual-task costs of making lexicality judgements while walking in young and older adults

This novel study explores language processing in a real-world context, namely walking in a street. It combines performing lexicality judgments while walking on a self-paced treadmill in a virtual environment that simulates the real world to create a dual-task paradigm to evaluate cognitive-motor interference in older adults and healthy young individuals.
