This study looks at how non-invasive brain stimulation affects learning new spoken words. The study uses **transcranial magnetic stimulation (TMS)**, a special method that uses magnets to stimulate brain areas. Researchers are interested in understanding how the brain learns and remembers words, especially in older youths aged 16-24. There are two groups: one group of typical learners and another with reading difficulties. Participants will have baseline **magnetic resonance imaging (MRI)**, a scan that takes pictures of the brain, before undergoing TMS. They will complete tasks involving made-up words to see how well they learn and remember them after TMS. The study will last for two weeks with some tasks repeated to compare results.

• The study involves two visits over two weeks, with tasks and MRI scans.
• No direct treatment or compensation is provided, but the study is non-invasive.
• There are risks if you have metal in your body or certain health conditions.
