Attention has been drawn to recent, expanding studies on Second Language (L2) online programs and problems with people with learning difficulties, including Attention Deficit Hyperactivity Disorder (ADHD). This group of learners suffers from feelings of detachment and low self-confidence due to their lack of Willingness to Communicate (WTC) in an online classroom. Thus, the current quasi-experimental study explored the impact of a supplementary intervention targeted at helping learners create, substantiate, and live up to their ideal L2 self-images on multivariate components of ADHD learners' WTC in online English classes. For this purpose, 29 Iranian ADHD learners selected through convenience sampling were divided into two equivalent groups based on their ADHD levels. The groups were then randomly assigned to an experimental (N = 15) and a control condition (N = 14). In the experimental group, the vision ignition intervention was integrated into a 10-week online English course, whereas the control group's learners received no vision-enhancement intervention throughout the course. The learners' WTC was measured through a standard psychometric survey at the outset and conclusion of the course. Multivariable Analysis of Covariance (MANCOVA) was conducted to determine whether a linear combination of the subcomponents resulted in significant differences between groups. Along with an overall significant between-group difference in WTC, the results revealed the intervention's significant impact on WTC's two subcomponents: communicative self-confidence and integrative orientation.
