Students were also asked to rate the interaction with the robot on a scale from 1 to 5, where 1 is apathetic and 5 is positive. The students acted as the “mother” in this situation the frequency and duration of their smiles were used as input by Diego-San. In this case, 32 UC San Diego undergraduate students participated in Messinger’s study. That is, it adjusts its behavior based on given input. Their infant-like robot, Diego-San, employs machine learning to adapt its behavior. After conducting a study with infants and mothers, Messinger and his colleagues utilized an interactive robot that closely mimics the appearance of an infant, with dynamic, lifelike facial expressions. In order to substantiate the idea that infants’ smiles were goal-oriented, Messinger and his team used principles of Control Theory-a discipline that deals with influencing dynamic system behavior, including robots and forms of artificial intelligence. Understanding infants’ early social behavior has the potential to strengthen our understanding of social development, and of disorders that occur early in development such as autism. Because mother-infant smiling is a critical point in social development, researchers took great interest in infants’ behavior. In a word, infants want to be “smiled at” by mothers. Mothers consistently sought to maximize the time that both they and the infant spent smiling, while infants sought to receive a smile from the mother even if she was not smiling. Furthermore, they found that mothers and infants have different goals when smiling in their interactions. Messinger and his colleagues found that when infants reach 4 months of age, the timing and duration of an infant’s smile reveals purposeful, goal-oriented behavior. Daniel Messinger, a Professor of Psychology at the University of Miami, has participated in extensive research that suggests intentional, goal-oriented behavior rooted in infants’ smiles. To an ordinary person, an infant’s smile may appear to be a simple expression of happiness or contentment-but some researchers have discovered deeper meaning associated with their smiles.ĭr.

Early childhood development has long been an elusive and mysterious topic for psychologists. To a mother, a newborn’s cheery smile is often the first of many meaningful interactions that will take place. The Social Systems Informatics Program is working on the following projects:įew things are as heart-warming as an infant’s smile. FOCUS AREA: SOCIAL SYSTEMS INFORMATICS Research
