Eligibility criteria

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. If you have already participated in "ALIENating Speech Sounds", please do NOT participate in this study.

Is your baby growing up hearing mostly or only (>90%) English? This study is no longer recruiting monolingual babies and is focusing on bilingual babies only. That said, we would love for you to participate in our other study 'Can You Hear the Difference?" on Lookit! Please note you will not receive a gift card if your child is not growing up with multiple languages and you proceed with participating in this study - please participate in "Can You Hear the Difference?" instead.

Duration 20 minutes

We will e-mail you a $5 Amazon e-gift card within 7 days of your participation in this study. Your child must be eligible for the study and visible on the webcam during the study. You may only participate once per eligible child who has NOT participated in the "ALIENating Speech Sounds" study.

What happens

In this study, your baby will watch dancing rainbow dots while hearing sequences of the two speech sounds ("ra" and "la"), 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 where you are selecting the sounds you hear.

What we're studying

This study explores how well infants between 5-12 months of age can differentiate between two difficult speech sounds in at least one of their first languages. The speech sounds used in this study can be difficult for adult native English speakers, therefore, we are interested in how infants will perform differently on this based on age and language exposure. We predict that babies who are older and have more experience with the speech sounds presented will tell apart the speech sounds better than babies who are younger and with less experience. This study will help us to better understand how babies become masters in their first language(s).

This study is conducted by Dr. Janet Werker (contact: infants@psych.ubc.ca )
