“…To explore this possibility, Kahrs, Lockman & Jung (2013, 2014) studied how 6–15 month-old infants bang a handled cube versus a simple cube. Younger infants’ percussive actions were even less controlled (i.e., more circuitous and faster) than when they were given a simple cube.…”

“…Adults achieve fine control of handled tools through involvement of the wrist (Marzke, 2013). Recent research suggests that this distinctively human pattern is an outgrowth of infants’ percussive behaviors (Kahrs, Jung, & Lockman, 2014). In a motion capture study of hammering in children between 19–35 months of age, younger children used a form of hammering that is very similar to one that infants display when they bang objects by relying on their proximal musculature (i.e., shoulder and elbow).…”

If tool use requires higher-level cognitive abilities, how is it that many animals show the capacity to use tools? New research on the development of human tool use offers a way to resolve this paradox. The research suggests that there is a developmental synergy between affordance detection and motor learning: As juveniles continually explore affordances entailed by object-surface combinations in real time, they tune the actions that will be incorporated into tool use over developmental time. We illustrate these ideas with research on how object banging in infancy serves as the motor substrate for later developing percussive tool use. Collectively, the new research suggests that basic types of tool use in young humans and animals are rooted not in higher-order cognitive abilities, but shared principles of sensorimotor learning.

“…From an early age, chimpanzees spend considerable amounts of time manipulating tool-suitable objects, particularly leaves and sticks, but mostly in a playful manner (Kahlenberg & Wrangham, 2010;McGrew, 1977). This propensity is likely to be an important precursor of tool use by providing individuals with essential perceptual-motor experience when interacting with the material world (Hayashi et al, 2006;Kahrs & Lockman, 2014).…”

Development of object manipulation in wild chimpanzees

Chimpanzees' natural propensity to explore and play with objects is likely to be an important precursor of tool use. Manipulating objects provides individuals with pivotal perceptualmotor experience when interacting with the material world, which may then pave the way for subsequent tool use. In this study, we were interested in the influence of social models on the developmental patterns of object manipulation in young chimpanzees (Pan troglodytes schweinfurthii) of the Sonso community of Budongo Forest, Uganda. This community is interesting because of its limited tool repertoire, with no records of stick-based foraging in over 20 years of continuous observations. Using cross-sectional data, we found evidence for social learning in that young individuals preferentially played with and explored materials manipulated by their mothers. We also found that object manipulation rates decreased with age, whereas the goal-directedness of these manipulations increased. Specifically, stick manipulations gradually decreased with age, which culminated in complete disregard of sticks around the age of 10 years, a pattern not found for other tool materials, which were all used throughout adulthood. Overall, young chimpanzees initially explored and played unselectively with any object found in the environment before becoming increasingly influenced by their mothers' goal directed object manipulations.

“…This possibility is supported by a recent series of studies using high-speed motion capture technology (Kahrs, Jung, & Lockman, 2012, 2013, 2014; Kahrs & Lockman, 2014). Infrared cameras recorded the three-dimensional position of reflective markers at 240 Hz.…”

Research on the development of tool use in children has often emphasized the cognitive bases of this achievement, focusing on the choice of an artifact, but has largely neglected its motor foundations. However, research across diverse fields, from evolutionary anthropology to cognitive neuroscience, converges on the idea that the actions that embody tool use are also critical for understanding its ontogenesis and phylogenesis. In this article, we highlight findings across these fields to show how a deeper examination of the act of tool using can inform developmental accounts and illuminate what makes human tool use unique.
