Research: Infants use a speaker’s gender to understand language

A new scientific study has shown that when learning language and processing speech, infants pay attention not only to the words being spoken but also to the social characteristics of the speaker. The study was conducted by Desia Bacon, a doctoral student in psychology, and Professor Jennifer Saffran. The findings were published in the scientific journal Infancy.

According to the researchers, people’s understanding of language depends on more than just the words they hear. During communication, factors such as facial expressions, gestures, tone of voice, and the social characteristics of the speaker also influence how information is interpreted and learned. For this reason, the researchers sought to determine whether children use information about social categories during language processing.

Social categories refer to the grouping of people based on certain characteristics. These include traits such as gender, race, socioeconomic status, and educational background. While adults frequently rely on information related to such categories in everyday communication, researchers had not yet fully determined how this process occurs in infants.

As part of the study, the researchers examined language processing in real time. This process allows a person to combine what they hear and see in order to anticipate what another person is likely to say next. Scientists believe that this method provides some of the most accurate insights into children’s language abilities.

The study used specialized eye-tracking technology to monitor children’s eye movements. Researchers explain that because the eyes respond more quickly than the hands, eye movements can reveal what information a person is processing and what they may be thinking about.

During the experiment, children sat on their parents’ laps in front of a screen. The screen displayed images of two familiar objects, such as a cup or a shirt. Although the objects themselves were neutral, their colors and patterns made them appear stereotypically “feminine” or “masculine.” For example, a cup might be presented in blue, while a shirt might feature a floral pattern.

A male or female voice then asked the children to find one of the objects displayed on the screen. Observations showed that when the speaker’s gender matched the gender-associated characteristics that children attributed to the object, infants identified the correct image more quickly and more accurately.

The findings indicate that infants are able to integrate information about social categories into language processing from a very early age. This suggests that children gather more information about the world around them than adults may realize.

According to the researchers, this study is among the first to connect the fields of social categories and language learning. They believe that the findings will help scientists better understand how children develop word meanings and what types of information they absorb from their environment.

The authors of the study plan to investigate how other social categories, in addition to gender, influence children’s language comprehension. They conclude that children learn not only about the functions of objects but also about how those objects are associated with particular groups of people, raising new scientific questions about language development.
