[see Surveying Sound: Your Baby’s First Critical Window
This study compared the effects of two different types of music exposure – Active and Passive – with no musical interventions in babies starting at 6 months of age, at the opening of this critical window. In the Active group, babies actively engaged in music playing and listening with their parent. In the Passive group, babies engaged in normal everyday play while Baby Einstein™ CD’s played in the background. The main differences between these groups was that the Active group reinforced learning through repetition, used positive social interaction to enhance learning, and emphasized music quality.
After six months the researchers tested their little subjects on their preference for Western tones, their ability to discriminate novel sounds, their emotional response to novel sounds, and their overall ability to communicate. In each parameter tested, the babies who had Active music exposure scored significantly higher than the other two groups. There was little difference between the Passive group and babies receiving no music interventions. Thus, this study concluded music enhances cognitive, emotional, and social development only when exposure is in the context of active learning and social interaction (Gerry, Unrau, & Trainor, 2012).
This need for social interaction in infant learning is echoed in research on language acquisition. Researchers have found that babies are only perceptive to foreign language sounds when they directly interact with another human ; babies exposed to foreign language through passive exposure such as watching a foreign speaker on tv (Kuhl, Tsao, & Liu, 2003) or watching Baby Einstein™ CD’s (DeLoache et al., 2010) do not learn the foreign language sounds.
All caretakers can likely attest that infants are social learners; If imitation is truly the highest form of flattery, then infants surely are the greatest charmers. However, the absolute need for this interaction to improve cognitive outcomes from learning experiences was unknown. These studies highlight a currently overlooked yet critical component of learning that is absent from most educational baby products on the market – the need for human interaction during the process of learning.
