In this insightful discussion, Karen Adolph, a professor at NYU and head of the Infant Action Lab, shares her groundbreaking research on how infants learn to move and think. Alongside her partner Mark Blumberg, they challenge traditional views of the motor cortex, revealing its role in processing sensory information rather than just motor functions. They dive into the importance of real-world observations in understanding development, the influence of ecological psychology, and how insights from infants can inform advances in artificial intelligence and robotics.
Observing infants' unique movement strategies reveals their creative problem-solving abilities and adaptability during early developmental stages.
Infants' embodiment and variability in movement are crucial for learning, allowing them to adapt to physical changes in their environment.
Ecological psychology highlights the role of environmental interactions in shaping motor behaviors and cognitive development throughout infancy.
Deep dives
Understanding Infant Behavior
Observing infants at various stages of development reveals crucial insights into the evolution of motor behaviors. The study of children’s interactions, such as their unique methods of hammering a peg, highlights their creative problem-solving abilities. For example, some children engage in unexpected techniques, like using their bodies to reposition the hammer, which demonstrates their adaptability. Exploring these behaviors provides a deeper understanding of how movement and cognition intertwine in early development.
The Role of Embodiment and Variability
The embodiment and variability of infants' movements are essential components of their learning process. Infants adapt to their physical changes and navigate their environment based on their accumulated experiences. This adaptive mechanism suggests that consistent exposure to diverse physical challenges enhances their capabilities, facilitating quicker and more effective learning. Recognizing that an infant’s interactions are inherently linked to their physical development challenges conventional approaches to studying cognitive mechanisms.
The Influence of Ecological Psychology
Ecological psychology significantly informs the understanding of developmental processes and motor behaviors. The foundational theories of James and Eleanor Gibson underscore the importance of direct perception and affordances in learning. Their ideas emphasize that behaviors are shaped by the environment, with organisms constantly interacting with their surroundings to adapt and learn. Integrating these ecological principles into developmental research highlights the intricate relationship between cognition, movement, and environmental context.
Challenges with Traditional Research Methods
Research methods such as looking time studies have long been used to infer cognitive processes in infants but are increasingly recognized as insufficient. Traditional measures often fail to account for the complexities of an infant’s gaze, which can be influenced by a variety of factors. This oversight suggests a need for advanced methodologies, such as eye tracking, to provide more nuanced and accurate insights into infants' cognitive engagement. The shift towards using modern technologies underscores the necessity of evolution in research paradigms to better reflect the intricacies of infant behavior.
Future Directions in Developmental Science and AI
The potential of AI and robotics to enhance understanding of human development is a burgeoning area of interest. By simulating robotic behavior inspired by infant learning processes, researchers can explore how movement and sensory experiences inform cognitive development. These simulations can reveal insights into how environmental interactions influence learning trajectories, paralleling the experiences of infants. As advancements in technology continue to evolve, integrating developmental principles into AI research promises to uncover new dimensions of learning and adaptation.

Karen Adolph runs the Infant Action Lab at NYU, where she studies how our motor behaviors develop from infancy onward. We discuss how observing babies at different stages of development illuminates how movement and cognition develop in humans, how variability and embodiment are key to that development, and the importance of studying behavior in real-world settings as opposed to restricted laboratory settings. We also explore how these principles and simulations can inspire advances in intelligent robots. Karen has a long-standing interest in ecological psychology, and she shares some stories of her time studying under Eleanor Gibson and other mentors.
Finally, we get a surprise visit from her partner Mark Blumberg, with whom she co-authored an opinion piece arguing that "motor cortex" doesn't start off with a motor function, oddly enough, but instead processes sensory information during the first period of animals' lives.
