Experience is Instrumental in Tuning a Link Between Language and Cognition: Evidence from 6- to 7- Month-Old Infants' Object Categorization

At 3-4 months, listening to human and nonhuman primate vocalizations boosts infants' cognition; by 6 months, only human vocalizations exert this cognitive advantage. We describe an exposure manipulation that reveals the powerful shaping role of experience as infants specify which sounds to link to cognition and which to tune out.

Perspectives on Sensation and Perception

2023
Source: Laboratory of Jonathan Flombaum—Johns Hopkins University The study of sensation—how signals are transduced from sensory organs, like the eyes—and perception—how the brain interprets these messages—has a rich history dating back to the 19th century, when great strides were made in understanding the properties of light and how they relate to the visual system. Importantly, such sensory and perceptual processes determine what we see, feel, taste, and hear in our surroundings. However, many...

This novel protocol is designed to assess the neural bases of social interaction in infants. The paradigm is designed to tease apart how various social inputs such as language, joint attention, and face-to-face interaction relate to infant neural activation. Infant EEG power is recorded during both social and nonsocial conditions.

FAQs
These auditory cues provide structure before infants can identify individual words. Rhythm helps reveal recurring timing patterns, stress highlights which parts of speech receive emphasis, and intonation tracks changes in pitch across an utterance. Together, they help infants organize the continuous speech signal and support the discovery of patterns that later contribute to communication and language learning.
Statistical learning allows infants to track which sound patterns occur together or recur across speech. Repeated exposure can make some combinations more predictable, helping infants form emerging speech categories from rapidly changing phonetic features. This process supports the gradual organization of the input and helps explain how regularities in everyday language contribute to later speech understanding.
Early sensitivity is broad, allowing infants to respond to distinctions across many possible language environments. During the first year, exposure strengthens distinctions that are relevant in the surrounding language while sensitivity to less familiar contrasts decreases. This tuning makes perception increasingly adapted to the infant’s language environment, linking experience with developmental change.
Infants must process rapidly changing phonetic features even before they produce words. As exposure helps organize these features into emerging categories, perception becomes better aligned with the sound distinctions used in the surrounding language. That developing organization provides an auditory foundation for later communication, because children can increasingly attend to and interpret speech patterns that matter in their environment.
Developmental psychology research examines how infants respond to speech cues, recurring sound patterns, and familiar or less familiar distinctions across early development. Researchers can compare patterns of sensitivity as infants gain experience with their language environment. These changes provide evidence about auditory processing, statistical learning, and the timing of perceptual tuning without requiring infants to produce words.
Caregiver interaction supplies part of the language environment through which infants encounter rhythm, stress, intonation, and recurring speech patterns. Studying this context helps researchers connect perceptual changes with everyday experience rather than treating speech input as isolated sounds. It also clarifies how early interaction may support the communication and cognitive development associated with emerging language abilities.
Patterns of early perceptual change can serve as developmental information when researchers investigate communication difficulties. In particular, differences in sensitivity to speech cues, recurring patterns, or language-specific contrasts may help identify how auditory processing and tuning unfold. These findings do not by themselves establish a difficulty, but they offer a way to study early indicators alongside broader communication development.
