“…Model simulation has revealed further insights into the processes underlying kinematic patterns in human reaching behavior. Schöner et al (2018) approximated the differences between human infant and adult reaches by simulating impairments in three areas: movement planning, movement timing, and motor control. They found that reaches were less smooth (aka more movement units) and no longer straight.…”

A defining feature of most primates is a hand with five fingers. Spider monkeys are an exception because they have four fingers and no thumb. Despite the prevalence of reach-to-grasp research in primates, it is not known how the lack of a thumb affects reaching and grasping in spider monkeys. Drawing on patterns that have been well described in human adults, human infants, and other nonhuman primates, this study characterized prehension in Colombian spider monkeys (Ateles fusciceps rufiventris). Monkeys reached for two differently sized food objects and reaches were digitized offline for two-dimensional kinematic analysis. Grasp strategy was coded from video as preshaped when the hand was adjusted to grasp the food before contact, or not preshaped when the hand was adjusted to grasp the food after contact. Monkeys exhibited variability in reach smoothness that contrasted with the typical pattern seen in other adult primates and instead resembled the pattern observed in human infants. Monkeys anticipated the object to be grasped approximately half of the time. Reaches where the hand was preshaped to the object were smoother than reaches where the hand was adjusted to grasp after object contact. For the small object, reaches with preshaping were straighter than reaches without preshaping. Results are the first evidence of kinematic signatures for reach-to-grasp actions in spider monkeys.

“…In addition, human robotics research based on a developmental embodiment perspective also provides a platform and model for the study of human cognition and motor development by allowing to control and observe the functional elements as well as the developmental processes to a degree which is not possible in living organisms (Pfeifer and Bongard, 2006;Hoffmann and Pfeifer, 2018). For example, based on a computational approach to developmental systems neuroscience, Schöner et al (2018) simulated a simple neural dynamic model of movement generation, serving as platform for discussing infants' developmental challenges as they learn to reach for objects. Also, based on this model, they were able to construct a neural inspired robot imitating the neural processes underlying the reaching behavior (Tekülve et al, 2019).…”

Embodiment research is at a turning point. There is an increasing amount of data and studies investigating embodiment phenomena and their role in mental processing and functions from across a wide range of disciplines and theoretical schools within the life sciences. However, the integration of behavioral data with data from different biological levels is challenging for the involved research fields such as movement psychology, social and developmental neuroscience, computational psychosomatics, social and behavioral epigenetics, human-centered robotics, and many more. This highlights the need for an interdisciplinary framework of embodiment research. In addition, there is a growing need for a cross-disciplinary consensus on level-specific criteria of embodiment. We propose that a developmental perspective on embodiment is able to provide a framework for overcoming such pressing issues, providing analytical tools to link timescales and levels of embodiment specific to the function under study, uncovering the underlying developmental processes, clarifying level-specific embodiment criteria, and providing a matrix and platform to bridge disciplinary boundaries among the involved research fields.
