"The clearly observable behaviors that identify infant hand-use preferences make the development of this sensorimotor form of lateralization a valuable model for evaluating the development of other forms of lateral asymmetries of function. The current study examined the relation of individual patterns of development of handedness for reaching for objects (prehension) to the emergence of handedness in role-differentiated bimanual manipulation (RDBM). RDBM requires each hand to perform different, but complementary, actions on one or more objects. Hand-use reference for reaching for and grasping objects was assessed in a sample of 85 infants from the period of 6- to 11-months of age using a validated handedness assessment that consists of a series of presentations of 34 common infant toys. At 11 and 14 months, hand-use preferences for RDBM were assessed while the infants were involved in semiplay activity in which they were presented with a series of 13 toys (20-40 s for each presentation). Results revealed no significant relationship between prehension handedness and handedness for RDBM. However, multi-level modeling of the prehension data revealed interesting developmental changes in prehension handedness that can only be identified by using monthly sampling intervals with longitudinal methods."--Abstract from author supplied metadata.

"Handedness development during infancy could be represented as a progressive expansion of a hand-use preference across a wider range of increasingly complex skills. The goal of the present study was to explore the development of role-differentiated bimanual manipulation (RDBM) during infancy as an expansion of the development of handedness for acquiring objects and unimanual manipulation. Infants were categorized according to their handedness status for acquiring objects (right-hand, left-hand, or no distinct hand-use preference). This status was determined from nine monthly assessments performed during 6-14 month period and resulted in a sample of 90 normally developing infants (30 right-handers, 30 left-handers, and 30 no preference infants). These infants were tested monthly from 9 to 14 months for unimanual manipulation and RDBM handedness. The results of the multilevel analyses showed that lateralization of handedness for toy acquisition increased during 6-12 month interval and decreased thereafter. Lateralization of handedness for unimanual manipulation and RDBM increased during 9-14 month period. Furthermore, handedness for toy acquisition was found to be positively related to handedness for unimanual manipulation, which, in its turn, was positively related to handedness for difficult, but not simple, RDBM. Also, handedness for toy acquisition was positively related to handedness for difficult RDBM. Thus, it was concluded that handedness for toy acquisition concatenates into unimanual handedness which further influences the development of RDBM handedness."--Abstract from author supplied metadata.

The cascade theory of handedness development (Michel, 1983, 2002) posits that hand preference for an earlier manual skill can concatenate into hand preference for the next manual skill. While a number of studies have examined the relation between infant handedness in two manual skills and have demonstrated that infant hand preference for an early developing manual skill cascades into a later developing manual skill, no research has focused on the relation between unimanual manipulations and role-differentiated bimanual manipulation in infancy. The current study examined the relation between unimanual manipulation and role-differentiated bimanual manipulation (RDBM) in infants across 9-14 months. Specifically, this study examined whether hand preference for unimanual manipulations predicted RDBM hand preference. Fisher's exact test was conducted to examine whether there were significant overlaps in handedness between unimanual hand preference and RDBM hand preference. A simple regression was performed to test whether unimanual z-scores predicted RDBM z-scores across 9-14 months. A repeated measures ANOVA was also conducted to examine changes in RDBM z-scores across 9-14 months in each unimanual hand preference group (right, left, no preference). The results indicated that hand preference for unimanual manipulation did not predict RDBM hand preference.

"Unimanual hand preference is a behavior in which one hand is used more often than the other when single-handedly manipulating objects. The progressive lateralization theory (Michel, 2002) of handedness proposes that handedness gradually concatenates during infancy as a cascade from initially a preference for contacting objects to acquiring them, to their unimanual manipulation, to the eventual emergence of a hand preference for role-differentiated bimanual manipulation (RDBM). Together, these behaviors represent the individual's handedness expressed across most manual skills. Thus, the theory posits that an early hand preference for object acquisition will predict a later preference for single-handed object manipulations. This proposal was examined by describing the development of hand-use preferences for unimanual manipulation of objects for 90 infants (57 males) tested monthly from 6 to 14 months. These 90 infants were obtained from a larger sample of 380 infants: 30 infants from a group of 45 with left hand-use preferences for acquiring objects were matched for sex and development of locomotion skills with 30 infants with a right hand-use preference and 30 with no hand preference for acquiring objects. Results showed that the frequency of unimanual manipulations is stable during the 6-14 month period. Multilevel modeling of unimanual manipulation trajectories for the three acquisition hand-preference groups revealed that hand-use preferences for unimanual manipulation become more prominent with age and the preference is predicted by the hand-use preference for object acquisition. Also, infants with a right-hand preference for object acquisition develop a hand-use preference for unimanual manipulation sooner than those with a left preference and infants without a preference for acquisition remain without a preference for manipulation."--Abstract from author supplied metadata.

Role-differentiated bimanual manipulation (RDBM) is a complex behavior requiring the complementary movement of two hands to achieve a common goal. The current study investigated the relation of RDBM efficiency (speed to complete a successful RDBM) with hand preference, toy type (simple/difficult), age, and hand used to perform the RDBM. This study observed 46 infants between the ages of 9 to 14 months, each with a different hand preference category. Changes in RDBM efficiency across time were examined across different hand preference groups for RDBMs performed on simple toys using the right hand. The analysis revealed that early-right preference infants had a steeper slope than the no-preference/left-preference infants. The same was true for right-preference infants (early- and late-) for RDBMs performed on difficult toys using the right hand. A mixed ANOVA revealed that there were decreases in RDBM times across age therefore RDBM efficiency improves as the infants get older, regardless of toy type, hand used, or hand preference. The results of the present study suggest that when exploring the development of hand preference, we should consider the influence of age, hand preference, and hand used.

Motor skills are a vital part of healthy development and are featured prominently both in physical examinations and in parents’ baby diaries. It has been known for a long time that motor development is critical for children’s understanding of the physical and social world. Learning occurs through dynamic interactions and exchanges with the physical and the social world, and consequently movements of eyes and head, arms and legs, and the entire body are a critical during learning. At birth, we start with relatively poorly developed motor skills but soon gain eye and head control, learn to reach, grasp, sit, and eventually to crawl and walk on our own. The opportunities arising from each of these motor milestones are profound and open new and exciting possibilities for exploration and interactions, and learning. Consequently, several theoretical accounts of child development suggest that growth in cognitive, social, and perceptual domains are influences by infants’ own motor experiences. Recently, empirical studies have started to unravel the direct impact that motor skills may have other domains of development. This volume is part of this renewed interest and includes reviews of previous findings and recent empirical evidence for associations between the motor domain and other domains from leading researchers in the field of child development. We hope that these articles will stimulate further research on this interesting question.

Accurate assessment of hand function is critical to any treatment regimen of the hand compromised patient. Hand Function is a practical, clinical book which provides the knowledge needed to distinguish the different dimensions of hand function, particularly impairment, disability and handicap. Beginning with an overview of basic principles and examination, subsequent chapters evaluate the hand function in specific afflicted populations, including the rheumatoid patient, the stroke patient, the trauma patient, the geriatric patient and the pediatric patient, as well as special populations such as diabetes mellitus patients and musicians. An appendix containing hand function scales essential to the assessment of disability is also included. Rheumatologists, physiatrists, hand surgeons, orthopedists, occupational therapists and physical therapists will all find Hand Function a useful and valuable addition to their clinical references.

This book addresses the central role played by development in cognition. The focus is on applying our knowledge of development in natural cognitive systems, specifically human infants, to the problem of creating artificial cognitive systems in the guise of humanoid robots. The approach is founded on the three-fold premise that (a) cognition is the process by which an autonomous self-governing agent acts effectively in the world in which it is embedded, (b) the dual purpose of cognition is to increase the agent's repertoire of effective actions and its power to anticipate the need for future actions and their outcomes, and (c) development plays an essential role in the realization of these cognitive capabilities. Our goal in this book is to identify the key design principles for cognitive development. We do this by bringing together insights from four areas: enactive cognitive science, developmental psychology, neurophysiology, and computational modelling. This results in roadmap comprising a set of forty-three guidelines for the design of a cognitive architecture and its deployment in a humanoid robot. The book includes a case study based on the iCub, an open-systems humanoid robot which has been designed specifically as a common platform for research on embodied cognitive systems .
