Early autism identification infant-sibling study
The Purdue University Developmental Studies Laboratory is conducting a study of developmental trajectories in infants at risk for autism spectrum disorders (ASD).
Laboratory visits include several play-based tasks at 12, 15, 18, 24 and 30 months of age. After each visit, families receive $50 compensation and a report detailing their child's developmental progress, including information on his/her language, motor and social skills.
To be eligible, infant siblings must be between 12 and 19 months of age and have an older sibling who currently has an ASD diagnosis or an older sibling who is typically developing. This research aims to assist early identification and treatment for children with ASD.
Study to evaluate how sounds are processed in the human brain
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 two-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, Lyles-Porter Hall, Room 3043.
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, be right-handed, have no history of brain injury or psychiatric problems, and have 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.

Study examining the associations between personality, romantic relationship satisfaction and couple interactions
Cohabiting and/or married couples who have been in a relationship for at least one year are needed for a study examining the associations between personality, romantic relationship satisfaction and couple interactions.
Participants, who must be between the ages of 18 and 35, will answer questionnaires online and in the lab as well as participate in tasks with their romantic partner. Each participant will be compensated $15 ($30 per couple) at the completion of the study.
Those interested in participating should contact firstname.lastname@example.org.
Study on dilemmas experienced by couples who have miscarried
Couples who have experienced a miscarriage within the last year and who are 18 years or older are needed for a study on social support in the context of miscarriage.
It is reported that 1 in 5 pregnancies end in miscarriage, or the unexpected pregnancy loss before 20 weeks' gestation. Although this is a common occurrence, the ramifications of the loss are often understated. Couples may face societal misconceptions, difficulty communicating, and a lack of support from social networks. This study hopes to understand the dilemmas that couples face in this context.
Participants will complete a 60- to 90-minute in-person interview and will be compensated for their time with a $10 gift card. Women and their spouses/partners will be interviewed separately. Participation is voluntary and confidential.

Study on the impact of drinking common beverages with breakfast on blood glucose and insulin levels
Participants with or without Type 2 diabetes 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 from an IV line. 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.
The principal investigator is Wayne Campbell, professor in the Department of Nutrition Science.
Study on smartphones usage and family vacation experiences
Researchers are recruiting participants for a study exploring how smartphone usage affects family vacation experiences, such as how smartphone usage changes the way family members interact with each other, how smartphone usage influences the way family members interact with the vacation destination, and how smartphone usage influences the post-trip recollection of the family vacation.
All participants must be age 18 or older, have experience using a smartphone and had a family vacation experience in the past two years. Participants will be asked to recall their recent vacation with family members and to describe their smartphone usage during the family vacation. The interviews will last about 40 minutes to an hour at a time and a place that is convenient to the participant.
Participants will receive a choice of either a $10 Apple Store gift card or a $10 Starbuck gift card upon the completion of the interview.

Study investigating protein and fiber at breakfast on brain activity, appetite and health
Wayne Campbell, professor in the Department of Nutrition Science, and his research team are recruiting men and women age 21-45 to participate in a research study to begin in January.
The purpose of this research study is to examine the impact of eating varying amounts of protein and fiber at breakfast on brain activity, appetite, blood cholesterol and blood sugar levels.
The study will take a minimum of 15-16 weeks to complete. Participants will complete one week of baseline testing and four two-week “breakfast given” phases, each separated by two-week “usual diet” phases. During each of the four two-week breakfast given phases, participants will be provided with and asked to eat specific breakfast meals every day. Participants will eat their usual diets during the usual diet phases. During the study, researchers will perform brain scans using functional magnetic resonance imaging (fMRI), measure diet, perform blood draws, and measure 24-hour blood sugar profile.
Participants will be given a $450 stipend at the completion of the study.
Those are interested in participating in this study are encouraged to contact Drew Sayer at email@example.com or 49-48313 for additional information.
Study on effects of daily timing of protein intake
This study will look at how within-day patterning of protein intake (even vs. skewed) combined with resistance training will influence changes in body composition, skeletal muscle and health during weight loss.
For this 18-week study, participants will come to the Purdue Clinical Research Center for eight testing days, which are before (baseline) and at the end of a 16-week weight loss intervention consisting of a controlled diet and resistance training program. Dietary counseling, gym memberships and personal trainers will be provided. Testing days will include measures of body composition (including muscle size), muscle strength and fitness, and clinical health parameters (i.e., blood pressure).
Participants will receive $1,000 for completing the study.
Men and women age 19 to 50 who are overweight, in general good health, nonsmokers, nonpregnant, and interested in participating in this study should contact Jan Green at firstname.lastname@example.org or 49-47660 for more information.
