Description

This is a simplified deterministic reinforcement learning paradigm combined with eye tracking, designed to be feasible for individuals with intellectual disability in the mild to moderate range. Each trial presented "a pair of pictures, and participants were required to choose one of the options", with win feedback indicated by a thumbs up and a sound and loss feedback by a thumbs down and a matched sound. "After four consecutive correct responses (wins), the reward contingency reversed without warning, resulting in a loss", and the task included five achievable blocks with a maximum of 25 trials. The authors state the paradigm "support[s] the use of this paradigm in ID populations and provide[s] a robust foundation for examining syndrome-specific differences in physiological feedback processing."

Design Implications

Context

Requirements

  • Instructions were given both in written and oral form and "adjusted based on the participant's receptive language skills", with two practice trials before the task.

Constraints

  • The task was intentionally simplified; the authors note the lack of observable adaptation difficulties likely reflects this simplicity rather than the absence of cognitive flexibility difficulties, and recommend more complex paradigms for future work.

Target Learners

  • Individuals with intellectual disability in the mild to moderate severity range, including Down, Fragile X, and Williams syndromes, aged 6 to 60 years

Learning Goals

  • Reinforcement learning: associating choices with rewards and losses from deterministic feedback
