The principal investigator for this study is Franki Kung, associate professor in the Department of Psychological Sciences. IRB-2024-1233.
Study on sensor-based estimation of nutrition and surrounding environment
Researchers need adult volunteers ages 18 and older to try a new mobile app and wearable device that records what they eat.
The purpose of this study is to test a mobile, image-based application and a wearable sensor to record the foods and beverages consumed in a day, and then complete an online dietary survey about the foods and beverage consumed over the same period of time.
The study will take around three days to complete, and participants will receive a maximum of a $40 gift card as compensation. Participants will also be asked to visit campus twice for about an hour each time to learn about the devices they will be using and wearing and to answer questionnaires.

Leveraging Interests and Nurturing Knowledge (LINK)
Learning new words can seem super easy, especially when many children do this so effortlessly. In reality, it is a very complex skill that we often take for granted. The research team’s goal is to figure out how to help students learn new words successfully.
Children learn words most easily when their classrooms are quiet and teachers use language in the same way that they do. Most classrooms are not like this (and this is completely normal). Classrooms should be full of excitement and overflowing with different ways of using language to communicate our thoughts and ideas. The research team’s goal is to understand the science behind word learning and find strategies that help children take on this difficult task, especially in classroom environments that mirror their everyday experiences.
Researchers are looking for students ages 6 to 8 who do not have delays in development and primarily hear and speak English at home. Participants will receive $55 in digital gift cards for their child’s participation and a speech-language and hearing screening for the child.
The study involves two 1.5-hour visits scheduled with the research team at Purdue. Children will play computer games, look at picture books and complete puzzles.
Individuals interested in participating can sign up at the study website, email Michelle Erskine at merskine@purdue.edu or call the lab at 765-496-0427. The principal investigator is Arielle Borovsky, professor in the Department of Speech, Language, and Hearing Sciences. IRB-2023-800.
Study on experience of migration, acculturation, adaptation and integration
The purpose of this study is to describe the experience of migration, acculturation, adaptation and integration of engineers from the U.S. territories who are pursuing careers in the contiguous United States.
Participants must:
- Have moved to the contiguous United States for the purpose of pursuing a career as an engineer.
- Currently work and live in the contiguous United States. Alaska and Hawaii are not currently eligible for participation in this study.
- Be age 18 or older and not fully retired from working.
- Fill out this survey to give the researcher some background information and double-check eligibility.
- Find a quiet place to take Zoom calls.
Each interview will last 1 1/2 hours. Three interviews will be conducted in total.
Participants will meet with the researcher to talk about their experience of moving and adjustment. The three interviews should be spaced with as short of breaks as possible. Participants will reflect on their experiences and feelings.
The format of the interviews are as follows:
- Interviews 1 and 2: Participants will answer several questions about moving to the contiguous United States.
- Interview 3: Participants will answer several questions about adjustment and acculturation in the workplace.
The researcher will record audio responses to ensure answers are captured verbatim. Participants will receive $56.25 ($12.50 an hour) through a private Venmo transfer at the end of Interview 3.

Researchers are looking for volunteers for a psychology study on practice and learning. Men and women ages 18-30 years who have normal or corrected-to-normal vision, and have normal or corrected-to-normal hearing may be eligible to participate. Participants will be asked to complete various computerized memory and attention tasks, responding to information presented visually onscreen or via headphones and using the computer keyboard or mouse to make responses.
This study involves 12 in-person visits to the lab (located in the Psychological Sciences Building on Purdue’s West Lafayette campus) over the course of no more than four weeks. The first and last sessions will last no more than 150 minutes, and participants will be compensated with a $25 Amazon.com gift certificate after each session. The other 10 sessions will last no more than 60 minutes, and participants will be compensated with a $15 Amazon.com gift certificate after each session. In addition, participants can earn bonus compensation for the completion of all 12 sessions within four weeks (a bonus $5 Amazon.com gift certificate). Participants who complete all 12 sessions of the study will be compensated with a minimum of $200 in Amazon.com digital gift certificates.

Parent-Adolescent Interaction Project
Researchers in the Biobehavioral Development Lab are looking for two-parent (mother and father) families with an adolescent child aged 9-13 years, all able to speak English. The study includes two, approximately two-hour lab visits starting between 4 p.m. and 6 p.m. any day of the week – one with the mother and teen, and one with the father and teen occurring about one week apart – and a daily diary (approximately 10 minutes/day) for 14 days.
The goal of the study is to see how parent-adolescent relationships affect the mental health and well-being of children. Researchers aim to learn about how parents and pre-teens feel, act and even biologically (stress hormones, heart rate, breathing) respond together during conversations — in similar ways or in opposite ways — and how what happens during conversations translates into daily patterns and parents’ and teens’ mental health and well-being. The information gathered in this study is intended to be used to develop ways to help improve parent-adolescent relationship quality and adolescents’ well-being.
Each participant will receive $30 per lab visit (cash) and $5 per daily diary (Amazon gift cards). Families completing both lab visits and all 14 days of the daily diary will receive $130 for the child and $100 for each parent.
For more information, visit the study website or email bdl@purdue.edu and mention “The Parent-Adolescent Interaction Project.” To check eligibility, take this survey. The principal investigator is Kristine Marceau, associate professor in the Department of Human Development and Family Science. IRB-2023-1734.
