Coming to Understand the Social and Physical Worlds
Children’s conceptual development has been described as a process of“theory change.” Specifically, children begin with an idea and then iteratively update that idea by combining existing and new information, making and testing predictions and then revising their idea based on new data again. Similar processes have been postulated to account for adaptive phenomenon in perceptual psychology and motor control. The similarities between the two processes suggest that performance on tasks that measure conceptual and sensory‐motor “theory change”respectively may be related. The goal of the present study is to determine whether children’s development in a complex conceptual domain, theory of mind, is associated with children’s performance in a load force adaptation paradigm. Theory of mind is broadly defined as the ability to understand how mental states, such as beliefs and desires, motivate ourown and other people’s actions. In contrast, load force adaptation is the ability to gradually adjust the amount of force exerted on an object in order to smoothly lift it up, as experience with the weight of the object is gained. To explore the mechanisms underlying these two processes, children between the ages of 3.5 and 4.5 years participate in a load force adaptation task and a battery of theory of mind tasks. We predict that since the underlying processes appear to be theoretically similar, the individual differences in the ability to adapt load force and in theory of mind ability will be positively correlated.
