Inclusion criteria
Inclusion criteria: healthy participants, age 18-35, proficiency with english, right-handedness
Exclusion criteria
Exclusion criteria: Participants without a high proficiency level in the English language will be excluded from the study. For the TMS part they will be asked to fill a standard questionnaire for neuromodulation studies to exclude any participant with contraindications to brain stimulation. EXAMPLE OF SAFETY SCREENING * Have you ever: o Had an adverse reaction to TMS? o Had a seizure? o Had an EEG? o Had a stroke? o Had a head injury (include neurosurgery)? * Do you have any metal in your head (outside of the mouth,) such as shrapnel, surgical clips, or fragments from welding or metalwork? (Metal can be moved or heated by TMS) * Do you have any implanted devices such as cardiac pacemakers, medical pumps, or intracardiac lines, cochlear implants, implanted brain stimulators, implanted defibrillator? (TMS may interfere with electronics and those with heart conditions are at greater risk in event of seizure) * Do you suffer from frequent or severe headaches? * Have you ever had any other brain-related condition? * Have you ever had any illness that caused brain injury? * Are you taking any medications? (e.g. Tricyclic anti-depressants, neuroleptic agents, and other drugs that lower the seizure threshold) * If you are a woman of childbearing age, are you sexually active, and if so, are you not using a reliable method of birth control? * Does anyone in your family have epilepsy? * Do you need further explanation of TMS and its associated risks? Participants will complete the Stress Tolerance Short Questionnaire as an additional screening. If participants score over 50 in this questionnaire, we will advise them not to continue with the study.
