Nature and Nurture

The concept of ontogenetic niche is used here to interpret how species-typical behaviors develop through active, context-dependent processes. Ontogenetic niches typically include social stimuli, such as those arising from parents, siblings, and others that provide 'nurturing' in the form of resources, stimulation, and affordances for development. This approach is a useful alternative to wrestling with artificial dichotomies such as nature-nurture.

Many contemporary theories of human cognition focus on the biochemical mechanisms that lie beneath the mind’s operations, while neglecting the historical and developmental aspects of the human mind. This article argues (1) that a processual form of thinking has been developing since the Modern Era. Furthermore, it maintains (2) that this particular form of thinking is intrinsically connected with the historical phenomenon of the scientific revolution. The paper studies Günter Dux’s innovative historico-genetic approach to the development of thought in historical (...) process. It also analyses the processual form of thinking under specific conceptual aspects of Alfred North Whitehead’s philosophy of organism. The present study also reveals (3) the connection between the developmental and the historical aspects of the evolution of thought. Overall, the study found (4) that there is an anthropological cognitive mechanism behind the historical forms of thought usually related to the elaborated figure of explanation. (shrink)

Lorenz proposed in his (1935) articulation of a theory of behavioral instincts that the objective of ethology is to distinguish behaviors that are “innate” from behaviors that are “learned” (or “acquired”). Lorenz’s motive was to open the investigation of certain “adaptive” behaviors to evolutionary theorizing. Accordingly, since innate behaviors are “genetic”, they are open to such investigation. By Lorenz’s light an innate/acquired or learned dichotomy rested on a familiar Darwinian distinction between genes and environments. Ever since Lorenz, ascriptions of innateness (...) have become widespread in the cognitive, behavioral, and biological sciences. The trend continues despite decades of strong arguments that show, in particular, the dichotomy that Lorenz invoked in his theory of behavioral instincts is literally false: no biological trait is the product of genes alone. Some critics suggest that the failure of Lorenz’s account shows that innateness is not well-defined in biology and the practice of ascribing innateness to various biological traits should be dropped from respectable science. Elsewhere (Ariew 1996) I argued that despite the arguments of critics, there really is a biological phenomenon underlying the concept of innateness. On my view, innateness is best understood in terms of C.H. Waddington’s concept of “canalization”, i.e. the degree to which a trait is innate is the degree to which its developmental outcome is canalized. The degree to which a developmental outcome is canalized is the degree to which the developmental process is bound to produce a particular endstate despite environmental fluctuations both in the development’s initial state and during the course of development. The canalization account differs in many ways to the traditional ways that ethologists such as Konrad Lorenz originally understood the concept of innateness. Most importantly, on the canalization account the distinction between innate and acquired is not a dichotomy, as Konrad Lorenz had it, but rather a matter of degree difference that lies along a spectrum with highly canalized development outcomes on the one end and highly environmentally sensitive development outcomes on the other end. Nevertheless, I justified the canalization account on the basis of a set of desiderata or criteria that I suggested falls-out of what seemed uncontroversial about Lorenz’s account of innateness (briefly): innateness is a property of a developing individual, innateness denotes environmental stability, and innate-ascriptions are useful in certain natural selection explanations (more below). From that same set of desiderata I argued (in my 1996) that neither the concept of heritability nor of norms of reactions—two concepts from population genetics—suffice to ground innateness. In this essay, I wish to provide further support of the canalization account in two ways. First, I wish to better motivate the desiderata by revisiting a debate between Konrad Lorenz and Daniel Lehrman over the meaning and explanatory usefulness of innate ascriptions in ethology. Second, I wish to compare my canalization account of innateness with accounts proposed by contemporary philosophers, one by Stephen Stich (1975), another by Elliott Sober (forthcoming), and a third by William Wimsatt (1986).

Historians of Biology have divided nineteenth century naturalists into two basic camps, Functionalists and Structuralists. This division is supposed to demarcate the alternative causal presuppositions working beneath research programs. If one is functionally oriented, then organic form will be contingent upon the causal powers of the environment. If structurally oriented, one argues for nonfunctional mechanisms (e.g., internal laws of growth) to account for organic form.Traditionally, Darwin has been grouped with the functionalists because natural selection (an adaptational mechanism) plays the prominent (...) role in shaping organic form. In this paper, I sketch the dichotomy of functionalism versus structuralism and then argue that Darwin cannot be characterized adequately with this dichotomy. I argue that Darwin can incorporate both causal stories because he makes two important modifications to the traditional metaphysical presuppositions. I then offer some brief reflections on the import of Darwin's causal pluralism for the Philosophy of Science. (shrink)

In response to the arguments of Bill McKibben and of Stephen Vogel that nature is at an end and that the very concept of nature should be discarded, I argue that, far from this being the case, the concept of nature is indispensable. A third sense of 'nature' besides the two distinguished by Vogel, that of the nature of an organism, is brought to attention and shown, through five arguments, to be indispensable for environmental philosophy and ethics, and for ethics (...) in general (veterinary and medical ethics included). But it is no coincidence that the same term is used for all three senses of'nature' in many languages. The indispensability of 'nature' in the third sense is used to suggest the indispensability of 'nature' in the second sense (things unaffected by human activity, a sense needed if we are to understand species whether wild or domesticated, because of their evolutionary history, and if we are to distinguish social systems from natural systems), and also of 'nature' in the first sense (things that are not supernatural, a sense needed if we are to ask metaphysical questions about whether 'nature' in this sense and in the other two might have a creator).

Adaptations during phylogenesis or ontogenesis can occur either by maintaning constant or by increasing the informational content of the organism. In the former case the increasing adaptations to external perturbation are achieved by increasing the rate of genome replication; the increased amount of DNA reflects an increase of total but not of law informational content. In the latter case the adaptations are achieved by either istructionist or evolutionary mechanism or a combination of both. Evolutionary adaptations occur during ontogenesis mainly in (...) the brain-mind, immunological and receptor systems and involve a repertoire of receptors that are., clonally distributed, genome-conditioned and amplified by somatic mutation. Specificity and intensity of responses are achieved a posteriori as a result of natural selection of the clones. The major adaptations during phylogenesis are accompanied by increased complexity. They have been attributed to shifts, short in time and space, against the entropic drive and thus occur notwithstanding the entropic drive and the second law of thermodynamics. The alternative view, is that the generation of complexity is due to the second law of thermodynamics in its extended formulation which includes Prigogine's theorem of minimum entropy production. This view requires however that natural selection provides the biological system with structures that bring the reactions within Onsager's range. The hierarchical organization of the natural world thus reflects a stratified thermodynamic stability. As the evolutionary adaptations generate new information they may be assimilated to Marxwell demon type of processes. (shrink)

Recently, there has been a growing interest, both within theoretical biology and the philosophy of biology, in the possibility and desirability of a theory of development. Among the many issues raised within this debate, the questions of the spatial and temporal boundaries of development have received particular attention. In this article, noting that so far the discussion has mostly centered on the processes of morphogenesis and organogenesis, we argue that an important missing element in the equation, namely the development of (...) language and cognition in general, may play an important role in settling the issue of temporal boundaries. After examining the idea that the development of language, cognition, and action are bona fide biological processes, we explore the consequences for a general theory of development of taking them into consideration.

In recent years, explanations of primate cognition highlighted clever arguments, rather than different ability. In the target article, definitions unify, explanations rely on basic nervous system functioning, theory is built on data that fit, and the emphasis is on evolutionary continuities. This commentary describes complexities inherent in the development of empathy that are not accounted for in Preston & de Waal's theory.

This chapter deals with the way our psychology and actions a scaffolded by their environment but also the tensions that can appear between individual and environment, both at the level of biology and culture. The chapter is grounded in an analysis of the early 20th century theoretical biologist Jacob von Uexkull and his notion of "Umwelt" or "surround world". But also raises the question of whether organisms fit their environment as neatly as Uexkull and many later thinkers have proposed or (...) assumed. (shrink)

An exploration of the nexus between ecology, evolutionary biology and molecular biology, via the concept of phenotypic plasticity.

The science of genetics is undergoing a paradigm shift. Recent discoveries, including the activity of retrotransposons, the extent of copy number variations, somatic and chromosomal mosaicism, and the nature of the epigenome as a regulator of DNA expressivity, are challenging a series of dogmas concerning the nature of the genome and the relationship between genotype and phenotype. According to three widely held dogmas, DNA is the unchanging template of heredity, is identical in all the cells and tissues of the body, (...) and is the sole agent of inheritance. Rather than being an unchanging template, DNA appears subject to a good deal of environmentally induced change. Instead of identical DNA in all the cells of the body, somatic mosaicism appears to be the normal human condition. And DNA can no longer be considered the sole agent of inheritance. We now know that the epigenome, which regulates gene expressivity, can be inherited via the germline. These developments are particularly significant for behavior genetics for at least three reasons: First, epigenetic regulation, DNA variability, and somatic mosaicism appear to be particularly prevalent in the human brain and probably are involved in much of human behavior; second, they have important implications for the validity of heritability and gene association studies, the methodologies that largely define the discipline of behavior genetics; and third, they appear to play a critical role in development during the perinatal period and, in particular, in enabling phenotypic plasticity in offspring. I examine one of the central claims to emerge from the use of heritability studies in the behavioral sciences, the principle of minimal shared maternal effects, in light of the growing awareness that the maternal perinatal environment is a critical venue for the exercise of adaptive phenotypic plasticity. This consideration has important implications for both developmental and evolutionary biology. (shrink)

This chapter, which deals with the psychological origins of goodness in childhood, and the developmental origins of human morality, argues that the socialization model and cognitive maturation model give short shrift to the role of emotions as one of the multiple natural prerequisites for nurturing morality. The primary models of moral development in the field of developmental psychology considered moral acquisition as a derived and “nurtured” consequence of inborn tendencies to either seek knowledge or gain social connection. Morality could not (...) possibly emerge out of hierarchical socialization. Socially constructed moral codes and feelings were derivative of natural emotional appraisal tendencies built on struggles for survival. Morality and convention were psychologically bound together, unified by the syntax of moral importance. The emotional transformation of socialized conventions into underlying moral competence can be likened to the transformation of everyday language performance into the innate syntactic structures indexing linguistic competence.

Charles Darwin is generally credited with having formulated the first systematic attempt to explain the evolutionary origins and function of the expression of emotions in animals and humans. His ingenious theory, however, was burdened with popular misconceptions about human phylogenetic heritage and bore the philosophical and theoretical deficiencies of the brain science of his era that his successors strove to overcome. In their attempts to rectify Darwin?s errors, William James, James Mark Baldwin and John Dewey each made important contributions to (...) a theory of emotion, which attempted to put it on a more secure philosophical and scientific footing. My contention is that Dewey and his collaborator, infant experimentalist Myrtle McGraw, succeeded where their contemporaries failed. They pointed the way out of the morass of recapitulationism, and showed how a developmental theory of consciousness, mind and emotion could be formulated that avoided the epistemological and ontological pitfalls of Darwin?s theory. Drawing on an extensive body of research from contemporary experimental studies of infant development, this essay attempts to put the questions raised by these historical figures about the structure, function and value of emotions in a theoretical framework. A developmental theory is proposed about the complex, interacting neurobiological and neurobehavioral factors that contribute to human emotional development. This theory identifies the possible relationships among emotions, consciousness and mind and how their co-development influences the capacity of young children to form moral judgments. (shrink)

The relationship between language and conceptual thought is an unresolved problem in both philosophy and psychology. It remains unclear whether linguistic structure plays a role in our cognitive processes. This special issue brings together cognitive scientists and philosophers to focus on the role of language in numerical cognition: because of their universality and variability across languages, number words can serve as a fruitful test case to investigate claims of linguistic relativism.

The performance of the Mundurucu on the number-space task may exemplify a general competence for drawing analogies between space and other linear dimensions, but Mundurucu participants spontaneously chose number when other dimensions were available. Response placement may not reflect the subjective scale for numbers, but Cantlon et al.'s proposal of a linear scale with scalar variability requires additional hypotheses that are problematic.

Does geometry constitues a core set of intuitions present in all humans, regarless of their language or schooling ? We used two non verbal tests to probe the conceptual primitives of geometry in the Munduruku, an isolated Amazonian indigene group. Our results provide evidence for geometrical intuitions in the absence of schooling, experience with graphic symbols or maps, or a rich language of geometrical terms.

More and more researchers are examining grammar acquisition from theoretical perspectives that treat it as an emergent phenomenon. In this essay, I argue that a robustly developmental perspective provides a potential explanation for some of the well-known crosslinguistic features of early child language: the process of acquisition is shaped in part by the developmental constraints embodied in von Baer’s law of development. An established model of development, the Developmental Lock, captures and elucidates the probabilistic generalizations at the heart of von (...) Baer’s law. When this model is applied to the acquisition of grammar, it predicts that grammatical achievements that are more generatively entrenched will emerge earlier in development and will be more developmentally resilient than those that are less generatively entrenched. I show that the first prediction is supported by a wealth of psycholinguistic evidence involving typically developing children and that the second prediction is supported by numerous studies involving both children who receive deficient linguistic input and children who experience various language impairments. The success of this model demonstrates the analytic potential of a developmental approach to the study of language acquisition. (shrink)

This article reviews recent research findings investigating developmental prosopagnosia. Studies involving DP address the cognitive and neural basis of face processing. The relatively rich cognitive, neural, and developmental theories of face recognition provide a framework that should allow for rapid progress. Cognitive studies of DP provide support for the existence of face-specific processes, and dissociations between different types of face processing in DPs are consistent with leading models of face processing that propose separable mechanisms for various aspects of face processing. (...) Research on the neural basis of DP has found abnormalities in a number of occipital and temporal regions that show face-selective responses in people with normal face processing, and so provide additional evidence that the integrity of these areas is necessary for face recognition. Despite progress made in recent years, much work remains to be done and connections between cognitive, neural, developmental, and genetic levels of explanation remain to be worked out. (shrink)

The 'developmental systems' perspective in biology is intended to replace the idea of a genetic program. This new perspective is strongly convergent with recent work in psychology on situated/embodied cognition and on the role of external 'scaffolding' in cognitive development. Cognitive processes, including those which can be explained in evolutionary terms, are not 'inherited' or produced in accordance with an inherited program. Instead, they are constructed in each generation through the interaction of a range of developmental resources. The attractors which (...) emerge during development and explain robust and/or widespread outcomes are themselves constructed during the process. At no stage is there an explanatory stopping point where some resources control or program the rest of the developmental cascade. 'Human nature' is a description of how things generally turn out, not an explanation of why they turn out that way. Finally, we suggest that what is distinctive about human development is its degree of reliance on external scaffolding. (shrink)

One of the most profound insights of the dynamic systems perspective is that new structures resulting from the developmental process do not need to be planned in advance, nor is it necessary to have these structures represented in genetic or neurological templates prior to their emergence. Rather, new structures can emerge as components of the individual and the environment self-organize; that is, as they mutually constrain each other's actions, new patterns and structures may arise. This theoretical possibility brings into developmental (...) theory the important concept of indeterminism--the possibility that developmental outcomes may not be predictable in any simple linear causal way from their antecedents. This is the first book to take a critical and serious look at the role of indeterminism in psychological and behavioral development. * What is the source of this indeterminism? * What is its role in developmental change? * Is it merely the result of incomplete observational data or error in measurement? It reviews the concepts of indeterminism and determinism in their historical, philosophical, and theoretical perspectives--particularly in relation to dynamic systems thinking--and applies these general ideas to systems of nonverbal communication. Stressing the indeterminacy inherent to symbols and meaning making in social systems, several chapters address the issue of indeterminism from metaphorical, modeling, and narrative perspectives. Others discuss those indeterministic processes within the individual related to emotional, social, and cognitive development. (shrink)

Sound comparative psychology and modern evolutionary and developmental biology (often called evo-devo) emphasize powerful effects of developmental conditions on the expression of genetic endowment. Both demand that evolutionary theorists recognize these effects. Instead, Tomasello et al. compares studies of normal human children with studies of chimpanzees reared and maintained in cognitively deprived conditions, while ignoring studies of chimpanzees in cognitively appropriate environments.

How is it possible that in more than one hundred years, the nature-nurture debate has not come to a satisfactory resolution? The problem, Dale Goldhaber argues, lies not with the proposed answers, but with the question itself. In The Nature-Nurture Debate, Goldhaber reviews the four major perspectives on the issue - behavior genetics, environment, evolutionary psychology and developmental systems theory - and shows that the classic, reductionist strategies are incapable of resolving the issue because they each offer a false perspective (...) on the process of human development. It is only through a synthesis of the two holistic perspectives of evolutionary psychology and developmental systems theory that we will be able to understand the nature of human behavior. (shrink)

The idea that some characteristics of an organism are explained by the organism's intrinsic nature, whilst others reflect the influence of the environment is an ancient one. It has even been argued that this distinction is itself part of the evolved psychology of the human species. The distinction played an important role in the history of philosophy as the locus of the dispute between Rationalism and Empiricism discussed in another entry in this encyclopedia. This entry, however, focuses on twentieth-century accounts (...) of the innate/acquired distinction. These accounts have for the most part been inspired by the sciences of mind and behaviour.

Developmental systems theory (DST) is a wholeheartedly epigenetic approach to development, inheritance and evolution. The developmental system of an organism is the entire matrix of resources that are needed to reproduce the life cycle. The range of developmental resources that are properly described as being inherited, and which are subject to natural selection, is far wider than has traditionally been allowed. Evolution acts on this extended set of developmental resources. From a developmental systems perspective, development does not proceed according to (...) a preformed plan; what is inherited is much more than DNA; and evolution is change not only in gene frequencies, but in entire developmental systems.

It is commonly accepted that thewestern view of humanity's place in nature isdominated by a dualistic opposition between nature andculture. Historically this has arisen fromexternalization of nature in both productive andcognitive practices; instances of such externalizationhave become generalized.

The philosophical challenge this perspective presents isto substitute concrete socioecological analysis forfoundational metaphysics.
