ALIENating Speech Sounds

For 5- to 12-month-old babies who are hearing mostly English (90-100% of the time ) OR who are hearing both English and another language (at least 30% of each). US/Canada only.

In this study, your baby will watch cartoon aliens labeling objects. First they will see familiar objects being labeled (e.g., banana) and then unfamiliar objects being labeled. The unfamiliar objects will be labeled with speech sounds that can be difficult to tell apart. Lastly, your baby will watch dancing rainbow dots while hearing sequences of the two speech sounds, and we will measure how long they look at the screen. Before the video for your baby, there is a brief task for you the parent: selecting the sounds you hear.

Learning "Mommy" Part 1

Babies who will turn 6 months within the next week and their maternal primary caregivers, US/Canada only

Can your little one tell if "mommy" is referring to you? In this study, we are interested to see how well your baby understands different types of word labels, especially to the label of a primary female caregiver they are routinely hearing (such as "mom", "mommy", or "mama", etc.). During this portion of the study, we will take a video clip of you (baby's primary female caregiver) and of your baby's hand to be shown to them later in a short video. This video will include those photos of you, as well as of other people, hands, and feet. We would record your baby's reactions to measure where they look and for how long!

Rhythm and Dance Study

For three to six-year-olds who speak English

In this study, you will complete a short survey about your child's experience with music, and then two tasks. In Task 1, your child will listen to cartoon animals playing the drums and pick the animals who are the best drummers for dancing (8-10 minutes). In Task 2, your child will dance along with drumming (about 5 minutes). For this, you will need to set up a "dance space" for your child to keep them in the camera frame, and for their safety while dancing. For the dance space, you could use a rug or foam mats on the floor, mark a space with masking tape, or set some pillows in a circle. The space should be at least 4' x 4' (approx. 1.2m x 1.2m).

Please have a short book, that your baby is already familiar with, ready for this. Next, you will be asked just to play with your baby for a few minutes. These tasks will be recorded, so please plan a space down on the floor and position your laptop/webcam so that you can both be seen.

What's their goal?

For babies aged 11 to 13 months who hear mainly English in their household and does not hear Spanish regularly; each child may only participate in this study once

In this study, your baby will first watch a video where two female experimenters will introduce themselves. After the introduction, your baby will watch a scene in which one of the experimenters will repeatedly select one toy over another. After a number of scenes, the placement of the toys will switch and the experimenter will continue selecting the same toy or a new toy. Your baby's looking behaviour will be recorded, and we’re interested in whether understanding someone’s language affects babies' ability to understand other people's goals. During the study, we will ask you to either keep your eyes closed or be turned around facing away from the screen. There will be more detailed instructions on how to hold your baby during the study!

Using words to learn more words!

For babies aged 14 to 16 months who learn English as their first language

In this study, babies watch short videos of a woman pointing to and naming a few familiar objects (“Look at the apple!” or "Do you see the banana?”). She then introduces a new word (“Dax”), but the object is hidden. Babies then see a pair of unfamiliar objects (e.g., a mango and an ottoman), and we record where they look when they hear that word ("Dax"). We ask parents to fill out a questionnaire at the beginning of the study.

Scene and Heard!

For babies ages 11.5 to 13.5 months. Because the study has a language component, there should be a native English speaker in the home.

In this study, your child will watch several videos of one kind of scene (like an indoor scene) labeled with a made-up word. Then, another example of that type of scene will be presented side-by-side with a new kind of scene (like a field). Your child might also see scrambled scenes. We use these to see how much a scene’s structure — versus its colors and textures alone — might help babies to categorize it. We’re interested in whether language draws babies’ attention to the information that differs between different kinds of scenes. Babies tend to look longer at things they find interesting, so we will measure how long your child looks at each scene to see if they find one more interesting than the other.
