Determining the Effects of Visual Feedback Delay on Interlimb Transfer of Visuomotor Adaptation

College of Health Sciences / Kinesiology


The objective of this study is to determine how providing offline visual feedback, as compared to online, will affect the pattern of interlimb transfer following visual motor learning.

Healthy young adults will perform targeted reaching movements under a rotated visual display condition with the left arm first (training), and then with the right arm (testing). Offline visual feedback will be provided immediately or 3 sec after the completion of each movement trial during the initial training session with the left arm. Subsequent performance with the right arm during the testing session will be compared across subjects in 3 different groups (online feedback, offline immediate, offline 3 sec).

Tasks and Responsibilities

| Student Tasks: Ms. Almanza has been working on a similar project in my lab during the spring semester. For this new project, she will continue to do the following tasks that she has done for the previous project: subject recruitment, data collection and data processing. In summer, she will also learn to analyze the data that she collected.

1. Subject recruitment: student will make and distribute flyers, contact and screen potential subjects over the phone, and make appointments with those who meet our inclusion criteria. When the subjects visit the lab, the student will collect consent forms.

2. Data collection: the student will test subjects using our movement data acquisition system independently.

3. Data processing: the student will process the data using a computer program called Matlab.

4. Data analysis: the student will learn to analyze the data using a statistical data analysis software called SPSS.
