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.

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.

"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 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 is a multidimensional phenomenon co-determined by polygenetic and developmental aspects, multifactorial influences and in some cases, pathological impact. It is important for professionals working with children, including those who are still undecided about their writing hand, to assess, analyse and understand the complexity of handedness comprehensively to prevent problems related to switched or atypical handedness. Beyond Left and Right Handedness uses a practice-based approach to handedness and systematically integrates theory, research and practice. Part I, ‘Theory and Research,’ critically evaluates and utilises the broad spectrum of the handedness literature as a theoretical basis for the development of handedness instruments. Part II, ‘Assessment and Analysis,’ presents diagnostic and analytical instruments developed by the author based on numerous in-depth studies and extensive clinical practice over 20 years. These include the Handedness Profile, a standardised assessment of various handedness dimensions; and the Handedness Typology, an analytical framework to interpret different types of handedness. Part III, ‘Implications for Practice,’ contains detailed case studies on assessment and treatment by professionals working with children presenting with unclear and/or atypical handedness. “This book provides the reader with a comprehensive and scholarly discussion of the topic, presenting a careful, in-depth description of all aspects of the topic and providing professionals with the necessary, evidence-based tools to address handedness in practice. It is an invaluable resource that is well situated in the latest evidence-based understanding of handedness and provides a comprehensive guide to addressing the important development of handedness.” - Prof. Dr. Helen Polatajko

Dexterous and autonomous manipulation is a key technology for the personal and service robots of the future. Advances in Bimanual Manipulation edited by Bruno Siciliano provides the robotics community with the most noticeable results of the four-year European project DEXMART (DEXterous and autonomous dual-arm hand robotic manipulation with sMART sensory-motor skills: A bridge from natural to artificial cognition). The volume covers a host of highly important topics in the field, concerned with modelling and learning of human manipulation skills, algorithms for task planning, human-robot interaction, and grasping, as well as hardware design of dexterous anthropomorphic hands. The results described in this five-chapter collection are believed to pave the way towards the development of robotic systems endowed with dexterous and human-aware dual-arm/hand manipulation skills for objects, operating with a high degree of autonomy in unstructured real-world environments.

This is a volume about the process of scientific discovery. Thirteen leading senior scientists, each interested in some aspect of behaviorial development, recount their intellectual journeys over the course of their careers and document their individual struggles to better understand and describe various developmental phenomena. Covering a broad range of topics, including perceptual, motor, social, and cognitive development, the contributors to this volume provide case-studies of how one pursues a long-term, systematic research program and how scientists continually formulate and reformulate their working conceptual frameworks based on their research results. Conceptions of Development provides a unique and personal, behind-the-scenes account of the process of scientific discovery, illustrating that useful and enduring scientific insight derives from the bidirectional interplay between empirical work and theory formulation. This volume will be of interest to a broad audience consisting not only of psychologists and psychobiologists interested in the study of development, but also teachers and students interested in behavioral development and its investigation, and the general reader interested in the process of scientific discovery.

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.
