Opt-Out Study Section: All children are eligible to participate UNLESS families complete an opt-out form indicating that they would NOT like their child to participate: 

Project on Social & Executive Learning in Early Childhood Tool (SELECT) (Ages 3-4 years)
This study, in collaboration with Prof. Yang in the HDQM department, explores the relationship between children's flexible social learning skills and their developing executive functions and language skills. Children will complete a series of tasks on an ipad where they will receive various cues such as symbols or word prompts. Their performance on these tasks will be compared across conditions. This project participates in the Open Science Framework, meaning that researchers from other programs will have access to data collected in this study. Children at the CYC are automatically enrolled in this study unless families complete the OPT-OUT form (second link below) by June 27th, 2025.

Subiaul Study Consent Form:
Note: You do not need to fill out the consent form if you wish to have your child participate, but please review it.

Opt-In Study Section: Consent forms will be distributed in children's cubbies. Families must return completed consent forms in order for children to participate.

Project on Children's Word Learning and the Environmental Context of Naturalistic Scenes (Ages 4 & 5 years) 
This project explores how children learn words depending on where they occur. The study involves (1) a parental survey (~10 minutes) and (2) two at-school visits (~30 minutes each). In the first visit, we will assess your child’s general language abilities using standardized instruments. In the second visit, your child will see unfamiliar objects on a screen while learning their names across different rooms of a virtual house (e.g., in a kitchen, a bathroom, a bedroom, a living room). While they listen to the words, an eye-tracker will measure their eye movements to the images on screen. Finally, the parental survey will ask questions about your child's demographics, language experience, and development.

Project on Children's Language Learning (Ages 3-6 years)
These studies help us learn about children's development in understanding language and thinking about the world and others. Each session takes about 15 minutes, and your child may be invited to participate in one or several sessions. In a session, a researcher will have some stories or a game setup showing in slides on a laptop or with physical props, and we record each child's answers and choices as, for example, Kermit asks for an explanation because he can't see what's on the other side of this wall, or the researcher asks which box the child wants to open after Olaf gave a clue.

Preschool Number Line Estimation (Ages 3-5 years)

This study’s primary aim is to examine the benchmark influences on children’s number line estimation performance and reveal children's ordinal understanding of numbers. The study will involve three activities for children as well as a short demographic survey for parents. For children, the first activity will entail playing games with a researcher involving pointing out the position of a number on the line. In the second activity, children will play one of the versions of benchmark in the number line game with a researcher. In the third activity, children will do the number line game with a researcher like in the first activity. Children ages 3- to 5-years old are invited to participate in this project.

Precision Memory in Preschoolers (3-5 years)

The purpose of this study is to understand children's precision memory, meaning the ability to distinguish objects that are similar to one another but not exactly the same. The study involves one session (about 30 minutes total) where your child will be presented with a series of pictures and be asked to make a judgement of the pictures (e.g., does the object in the picture belong inside or outside).
