This chapter examines the importance of studying hand preference together with different expressions of behavior. Cognitive differences between left- and right-handed primates are discussed. As shown in several species of primate, eye preference, but not hand preference, is biased at the level of the population and reflects hemispheric asymmetry of processing. Hand preference, determined from simple grasping of pieces of food and taking them to the mouth, is consistent for individuals but it is not population biased...

Most humans report preferring the right hand for a variety of manual actions. Additionally, most humans perform motor tasks better with their right hand, particularly among right-handed individuals, but less so among left-handed people. Some have suggested that asymmetries in performance rather than hand preference may better reflect left hemisphere specializations in motor functions. In contrast to humans, research on performance asymmetries in manual tasks by nonhuman primates has received far less empirical investigation...

In this chapter, we review hemispheric differences for sensorimotor function and cognitive abilities. Specifically, we examine the left-hemisphere specialization for visuomotor control and its interplay with language, executive function, and musical training. Similarly, we discuss right-hemisphere lateralization for haptic processing and its relationship to spatial and numerical processing. We propose that cerebral lateralization for sensorimotor functions served as a foundation for the development of higher cognitive abilities and their hemispheric functional specialization...

Cerebral lateralization and associated motor behaviors were historically thought to be characteristics unique to humans. Today, it is clear that these features are present and visible in other animal species. These shared attributes of brain and behavior suggest inheritance from a distant common ancestor. Population-level motor biases are likely to reflect an early evolutionary division of primary survival functions of the brain's left and right hemispheres. In modern humans, these features may provide a foundational platform for the development of higher cognitive functions, inextricably cementing the ties between the evolution and development of cognition...

Hand preference is a sensorimotor skill whose development both reflects and promotes the development of hemispheric lateralization for manual and cognitive functions. Extensive comparative, crosscultural, and paleoanthropological evidence demonstrates the prevalence of limb lateralized preferences across vertebrate species and the prevalence of right-handedness within hominid evolution. Many reviews of the evolution and development of human handedness have proposed adaptive explanations for its evolution. However, during the last 3 decades a new approach to understanding evolution (the Extended Evolutionary Synthesis-EES) provided a persuasive alternative to the conventional (Neo-Darwinian Synthetic Theory-ST) evolutionary and developmental accounts...

The study of brain and behavioral lateralization in so-called "lower vertebrates" (fish, amphibians, and reptiles) has received increasing attention in the last years, in an attempt to understand its phylogenetic origins and evolutionary significance. Observations on the earliest tetrapods, the amphibians, have helped us to understand the evolution of limb preference and suggest that laterality could have appeared even prior to the evolution of tetrapods. Insights into lateralized behaviors in fish-such as the turning behavior-have had an important role in uncovering proximate and ultimate causes of motor lateralization in the vertebrate subphylum...

Body cognition and lateralization can be investigated in fossils by integrating anatomical and functional aspects. Paleoneurology cannot provide strong evidence in this sense, because hemispheric asymmetries are shared in all extinct human species, and motor cortical areas are difficult to delineate in endocranial casts. However, paleoneurological analyses also suggest that modern humans and Neanderthals underwent an expansion of parietal regions crucial for visuospatial integration and eye-hand-tool management...

Behavioral lateralization is widespread across the animals, being found in numerous vertebrate species as well as in species from across many invertebrate phyla. Numerous recent studies have focused on lateralization in the insects, exploring the behaviors themselves as well as their neural basis and the possible selective pressures that led to their evolution. Lateralization in the insects can occur in any sensory modality and may be generated by peripheral or central neural asymmetries. The lateralization of particular insect behaviors can show either population-level or individual-level lateralization but which of these types of lateralization is present is strongly influenced by their social environment...

To understand the evolution of lateralized motor biases and cognitive functions, we rely on archeological methods to give us a window onto the past. Currently, the overwhelming majority of prehistoric data on asymmetry and laterality concern only the hominin lineage, spanning the time period from the presumed evolutionary split with the other great apes around 6-8 million years ago until the present day. We present an overview of these data from paleontology and archeology. Lateralized motor biases and anatomical asymmetries are evident throughout prehistory, showing increases in the predominance of right-handedness over time...

Split-brain patients constitute a small subpopulation of epileptic patients who have received the surgical resection of the callosal fibers in an attempt to reduce the spread of epileptic foci between the cerebral hemispheres. The study of callosotomy patients allowed neuropsychologists to investigate the effects of the hemispheric disconnection, shedding more light on the perceptual and cognitive abilities of each hemisphere in isolation. This view that callosotomy completely isolates the hemispheres has now been revised, in favor of the idea of a dynamic functional reorganization of the two sides of the brain; however, the evidence collected from split-brain patients is still a milestone in the neurosciences...

Though superficially symmetrical, the human face expresses emotion asymmetrically. Darwin (1872) first noted this phenomenon, conceding to being at a loss to explain why expressions such as smiling and sneering defiance were predominantly one-sided. Emotion lateralization offers a plausible account. Because the lower two-thirds of the face is contralaterally controlled, the emotion-dominant right hemisphere innervates the lower left hemiface, resulting in more intense expressions. Thus whether smiling or sneering, humans show stronger emotion on the left side of the face...

Structural and functional differences between the two cerebral hemispheres constitute one of the most fundamental aspects of brain organization. It is well established that functions related to language and motor behaviors are more strongly represented in the left hemisphere. Individuals with autism spectrum disorder (ASD) show impairments particularly in social communication, language, and a variety of motor-related symptoms, alongside intact or enhanced right hemisphere functions. This pattern of deficits and strengths has given rise to theories, suggesting that the neuropathology of ASD involves atypical hemispheric specialization...

The literature on the relationship between handedness and cognitive ability is riddled with studies using different conceptualizations of handedness (e.g., hand preference vs hand skill, direction vs degree, consistency vs inconsistency) and different conceptualizations of cognitive ability (intelligence vs distinct abilities), as well as different measurements thereof. Recently the literature was summarized by means of meta-analytic techniques. The findings show quite robustly that when handedness is assessed as hand preference and individuals are classified according to direction (i...

A relationship between motor control and speech lateralization has long been postulated by researchers and clinicians with an interest in the functional organization of the human brain. Exactly how motor control might be related to speech representation, however, is rarely examined. This chapter examines current issues relating to the organization, development, and measurement of motor control and speech representation. We further consider from neuropsychological, developmental, neurological, and genetic perspectives that speech and fine motor control involve planning and sequencing processes, which are mediated by an integrated neural network localized to the left hemisphere...

Findings on nonprimate mammals place the issue of mother-infant lateralized relations in a broader context, demonstrating that humans are one of many species showing this feature. The remarkable interspecies consistency in the direction of lateralization points to a continuity between lateralized mother-infant interactions in primates and nonprimate mammals and suggests ancient evolutionary roots of human cradling bias. The results from species which, in contrast to primates, have no direct involvement of forelimbs in mother-infant spatial interactions clearly support the perceptual origin of this type of lateralization...

Empirical aesthetics in general, and neuroaesthetics in particular, have been very much influenced by Berlyne's psychobiological program. For him, aesthetic appreciation involved the brain's reward and aversion systems. From this point of view, art constitutes a set of potentially rewarding stimuli. Research has certainly made great advances in understanding how the process of artistic valuation takes places, and which brain circuits are involved in generating the pleasure we obtain from artistic practices, performances, and works...

Cross-cultural empirical aesthetics seeks to determine whether the psychological processes underlying aesthetic preference are universal. Here we provide a critical review of the field's origin, development, and current state. Our goal is to evaluate the evidence and separate what is actually known from what is only assumed. We conclude that the evidence shows that people from different cultures base their aesthetic preference on a common set of formal features, including symmetry, complexity, proportion, contour, brightness, and contrast...

All creative activity brings about change, since it results in the production of something that did not previously exist. The act of creation is itself influenced by changes that have been previously brought about by others, including previous acts of creation. As with any human behavior, creativity has both biological and cultural aspects and is therefore influenced by biological as well as cultural evolution. However, biological evolution operates slowly and over a much longer timescale than cultural evolution, and change occurring within a human lifetime must be driven by cultural and social, rather than biological processes...
