Researchers in various studies looking for participants
Here is a list of research studies that currently are looking for participants.
Study on color combination semantics
Participants are being sought to take an online survey on color combination semantics. Researchers are studying how color combinations are perceived and what meanings are associated with them in different cultures.
The survey is available at https://purdue.qualtrics.com/SE/?SID=SV_1AqhT38FJKZ5Vrf. Participants will see a color combination and 12 categories of words, and then will be asked to choose which categories apply to the color combination. The survey takes approximately 15 minutes.
The survey is part of the doctoral research studies of Ali Jahanian under the supervision of S.V.N. Vishwanathan, associate professor of statistics and computer science, and Jan Allebach, the Hewlett-Packard Distinguished Professor of Electrical and Computer Engineering.
Questions should be directed to Jahanian at firstname.lastname@example.org.
Study to develop a gesture recognition system for people with quadriplegia
The School of Industrial Engineering is looking for men and women age 18-65 with severe upper limb mobility impairments to participate in a research study to develop a gesture recognition system for people with quadriplegia due to paralysis or limited motor function. This gesture recognition system allows quadriplegics to control robots and other technologies by using only gross arm movements.
Participants are required to perform a set of defined gestures following a slideshow. The experiment will last about 50-60 minutes at Michael Golden Laboratories (MGL), Room 1332.
The principal investigators are Juan Wachs, assistant professor of industrial engineering, and Brad Duerstock, associate professor of engineering practice. For more information, contact Hairong Jiang at email@example.com or 765-586-9038.

Study on the impact of drinking common beverages with breakfast on blood glucose and insulin levels
Participants are being sought to participate in a study that will look at how drinking different common beverages (milk, low-fat milk, nonfat milk, orange juice, coffee and water) with a meal changes blood sugar and insulin levels after eating.
Participants will come to Purdue Clinical Research Center on six mornings separated by at least one week. On each of the mornings, participants will consume a breakfast with one cup of a beverage. Blood samples will be taken before and every 30 minutes after eating for four hours to test blood sugar and insulin levels. Each test day will last about five hours.
Measurements include calories and nutrients in the participant's diet, weight/height/lean tissue, and blood glucose and insulin levels. Participants will receive $500 for completing the study.
Men and women ages 35 to 65 who are overweight, nonsmoking, not pregnant and interested in participating in this study should contact Jia Li at firstname.lastname@example.org or 49-41706 for more information.

Study on how pitch is processed in the auditory system
English- and Chinese-speaking adults with normal hearing are needed for an experimental study to evaluate how sounds are processed in the human brain.
Subjects will participate in a minimum of two 2-hour research sessions. Subjects will be asked to fill out forms before the actual experiment. The experimental procedure consists of recording electrical activity from the brain (using EEG-type electrodes attached to the head) in response to various sounds presented through headphones at comfortable listening levels. The subject's task is to lie back and relax on a recliner situated in a sound-treated booth.
There will be about 40 subjects in the study. All research will be performed in the Auditory Electrophysiology Laboratory, Heavilon Hall, Room B15.
Participation in the study is voluntary. Participants who withdraw from the study before completion will receive compensation pro-rated based on amount of time completed. Payment will be given to subjects in the form of cash at the end of each session.
All subjects must be 20-35 years old, right-handed, have no history of brain injury or psychiatric problems, and normal hearing sensitivity by self-report.
Chinese subjects must be native speakers of Mandarin from mainland China, have received formal instruction in English no earlier than age 9, and have no more than three years of music training on any combination of instruments.
English-speaking subjects must be native English speakers from the United States, must have no familiarity with spoken Chinese or any other tone language and have no more than three years of music training on any combination of instruments.

Studies on learning in children
The Cognition and Learning Laboratory at Purdue is looking for children in grades 4 and 5 to participate in a study on learning. The overall purpose of the research is to examine the effectiveness of different study strategies.
The study will involve two brief sessions lasting about 30 to 60 minutes. In an initial session, children will use different learning strategies while they read brief passages about science topics. In a second session one week later, the children will answer questions about ideas and concepts from the passages. The purpose of the research is to identify the strategies that produce the best long-term learning. The total duration of participation may vary from one to two hours.
The parent/adult and child will be paid $5 for every half-hour of participation. The minimum amount of compensation is $10 and the maximum amount is $20. To participate or for more information, visit http://learninglab.psych.purdue.edu/parents/ or email firstname.lastname@example.org.
