Feedback delivered during motor practice can help promote motor skill learning and promote confidence. However, the optimal way to provide feedback to promote learning and confidence is unknown. This project will study how the feedback that is provided during practice of a movement skill can help people learn and build confidence. The investigators will measure motor skill performance and confidence before and after a session of motor practice.
Feedback may be a useful tool to optimize motor learning during practice. For example, feedback during practice that indicates the learner is performing above average (i.e. positive social comparative feedback) enhances motor skill learning and self-efficacy in healthy adults. While this type of feedback is hypothesized to promote learning in some tasks, no studies have examined whether positive social comparative feedback during practice promotes motor learning in a traditional motor sequence task. Therefore, the aim of the proposed project is to investigate the effect of positive social comparative feedback on the learning of a joystick-based motor sequence task in healthy adults. The study aims to recruit 60 participants who will be randomized into 1 of 3 feedback groups (control group, performance feedback, and performance plus positive feedback). Participants will practice a motor sequence task on a single day and then return for retention performance testing about 24 hours later. Changes in performance (response time to complete a sequence) and self-efficacy will be measured from baseline to 24 hours later at retention.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Control | Active Comparator | Practice of a joystick based motor sequence task. Participants receive feedback that they have completed the practice trials in that block of practice. |
|
| Performance Feedback | Experimental | Practice of a joystick based motor sequence task. Participants receive feedback on their response time to complete the trials in the practice block. |
|
| Performance plus Positive Feedback | Experimental | Practice of a joystick based motor sequence task. Participants receive feedback on their response time to complete the trials in the practice block plus positive social comparative feedback. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Motor Sequence Task | Behavioral | Participants will be seated at a laptop with the right hand on a standard joystick. The movement of the joystick will move a cursor on the computer screen. Targets will appear on the laptop screen as a circle in one of twelve spatially distinct locations. The learner must move the joystick "cursor" to inside the target before the next target will appear. |
| Measure | Description | Time Frame |
|---|---|---|
| Response Time | Time to complete one sequence | Change from baseline to retention at 24 hours |
| Task Confidence | Self-reported confidence in ability to complete a sequence in a given time on a scale of 0 to 10 with a 10 equating to higher confidence | Change from baseline to retention at 24 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Peak Velocity | Average speed to capture a target within a sequence | Change from baseline to retention at 24 hours |
| Peak Velocity | Average speed to capture a target within a sequence |
