Most theories of learning would predict a gradual acquisition and refinement of skills as learning progresses, and while some highlight exponential growth, this fails to explain why natural cognitive development typically progresses in stages. Models that do span multiple developmental stages typically have parameters to “switch” between stages. We argue that by taking an embodied view, the interaction between learning mechanisms, the resulting behavior of the agent, and the opportunities for learning that the environment provides can account (...) for the stage-wise development of cognitive abilities. We summarize work relevant to this hypothesis and suggest two simple mechanisms that account for some developmental transitions: neural readiness focuses on changes in the neural substrate resulting from ongoing learning, and perceptual readiness focuses on the perceptual requirements for learning new tasks. Previous work has demonstrated these mechanisms in replications of a wide variety of infant language experiments, spanning multiple developmental stages. Here we piece this work together as a single model of ongoing learning with no parameter changes at all. The model, an instance of the Epigenetic Robotics Architecture embodied on the iCub humanoid robot, exhibits ongoing multi-stage development while learning pre-linguistic and then basic language skills.

In contrast with the two dominant views in Theory of Mind development, the Perceptual Access Reasoning hypothesis of Fabricius and colleagues is that children don’t understand the mental state of belief until around 6 years of age. Evidence for this includes data that many children ages 4 and 5, who pass the standard 2-location false belief task, nonetheless fail the true belief task, and often fail a 3-location false belief task by choosing the irrelevant option. These findings can be explained (...) by the PAR hypothesis but pose challenges for the two dominant views. I argue against an alternate hypothesis which is proposed by Anika Fiebich in a recent paper. According to Fiebich, PAR is not a distinct transitional stage in children’s theory of mind development, but is a fast and frugal System 1 heuristic which fades once children become fluent in social reasoning. However, I point out a number of problems with Fiebich’s proposal and argue for the superiority of the PAR hypothesis. I also present five reasons to be skeptical about the findings of Perner and Horn which purportedly show that 4- and 5-year-olds can pass the 3-location false belief task when suitably modified. This is a further difficulty for Fiebich’s proposal, since she relies on these findings in her fluency theory. Finally, I sketch a dual systems theory of mind account based upon the PAR hypothesis which is different from Fiebich’s. (shrink)

Model organisms became an indispensable part of experimental systems in molecular developmental and cell biology, constructed to investigate physiological and pathological processes. They are thought to play a crucial role for the elucidation of gene function, complementing the sequencing of the genomes of humans and other organisms. Accordingly, historians and philosophers paid considerable attention to various issues concerning this aspect of experimental biology. With respect to the representational features of model organisms, that is, their status as models, the main focus (...) was on generalization of phenomena investigated in such experimental systems. Model organisms have been said to be models for other organisms or a higher taxon. This, however, presupposes a representation of the phenomenon in question. I will argue that prior to generalization, model organisms allow researchers to built generative material models of phenomena – structures, processes or the mechanisms that explain them – through their integration in experimental set-ups that carve out the phenomena from the whole organism and thus represent them. I will use the history of zebrafish biology to show how model organism systems, from around 1970 on, were developed to construct material models of molecular mechanisms explaining developmental or physiological processes.

Arthur Danto has written:I came to view that in writing about beauty as a philosopher, I was addressing the deepest kind of issue there is. Beauty is but one of an immense range of aesthetic qualities, and philosophical aesthetics has been paralyzed by focusing as narrowly on beauty as it has.

It is not simply among the values we live by, but (...) one of the values that defines what a fully human life means.1Because beauty is so important to being human, it is worthwhile to study how people understand their experiences of beauty across the lifespan.

Idealization is a reasoning strategy that biologists use to describe, model and explain that purposefully departs from features known to be present in nature. Similar to other strategies of scientific reasoning, idealization combines distinctive strengths alongside of latent weaknesses. The study of ontogeny in model organisms is usually executed by establishing a set of normal stages for embryonic development, which enables researchers in different laboratory contexts to have standardized comparisons of experimental results. Normal stages are a form of (...) idealization because they intentionally ignore known variation in development, including variation associated with phenotypic plasticity (e.g. via strict control of environmental variables). This is a tension between the phenomenon of plasticity and the practice of staging that has consequences for evolutionary developmental investigation because variation is conceptually removed as a part of rendering model organisms experimentally tractable. Two compensatory tactics for mitigating these consequences are discussed: employing a diversity of model organisms and adopting alternative periodizations. (shrink)

One prominent image of the Christian life in Scripture is that of a journey homeward. Consistent with Scripture and the developmental sciences, Christian spiritual authorities through history have developed various journey paradigms with associated phases or stages and transitions. Constructive paradigms are not linear and rigid in form, but might be represented as upward trending spiral movements that permit digressions, reversions, stopping places and advances on the way. Such paradigms and stages serve valuable heuristic functions in assisting pilgrims (...) to assess where they are on the journey and how to progress in maturity as well as insights for guiding others on their journeys of faith.

The conditions animals experience during the early developmental stages of their lives can have critical ongoing effects on their future health, welfare, and proper development. In this paper we draw on evolutionary theory to improve our understanding of the processes of developmental programming, particularly Predictive Adaptive Responses (PAR) that serve to match offspring phenotype with predicted future environmental conditions. When these predictions fail, a mismatch occurs between offspring phenotype and the environment, which can have long-lasting health and welfare effects. (...) Examples include metabolic diseases resulting from maternal nutrition and behavioral changes from maternal stress. An understanding of these processes and their evolutionary origins will help in identifying and providing appropriate developmental conditions to optimize offspring welfare. This serves as an example of the benefits of using evolutionary thinking within veterinary science and we suggest that in the same way that evolutionary medicine has helped our understanding of human health, the implementation of evolutionary veterinary science (EvoVetSci) could be a useful way forward for research in animal health and welfare.

Developmental systems theory is an attempt to sum up the ideas of a research tradition in developmental psychobiology that goes back at least to Daniel Lehrman’s work in the 1950s. It yields a representation of evolution that is quite capable of accommodating the traditional themes of natural selection and also the new results that are emerging from evolutionary developmental biology. But it adds something else - a framework for thinking about development and evolution without the distorting dichotomization of biological processes (...) into gene and non-gene and the vestiges of the ‘black-boxing’ of developmental processes in the modern synthesis, such as the asymmetric use of the concept of information. Phenomena that are marginalized in current gene-centric conceptions, such as extra-genetic inheritance, niche construction and phenotypic plasticity are placed center stage. (shrink)

Late lung development comprises the formation of the terminal sac followed by the subdivision of the terminal sac by septa into alveoli and results in the formation of the gas‐exchange surface of the lung. This developmentally regulated process involves a complex epithelium–mesenchyme interaction via evolutionarily conserved molecular signaling pathways. In addition, there is a continuous process of vascular growth and development. Currently there are large gaps in our understanding of the molecular mechanisms involved in the formation of the gas‐exchange surface. (...) In this review, we attempt to integrate and reconcile the morphologic features in late lung development with what is known about the molecular basis for these processes. We describe the formation of the terminal sac and the subsequent formation of the septa, which divide the terminal sac into alveoli, in terms of the classically described developmental stages of induction, morphogenesis and differentiation. We believe that evolutionarily conserved pathways regulate this process and that morphogen gradients are likely to be a central mechanism. In addition, we highlight the importance of the molecular mechanisms involved in the simultaneous development of the vascular bed and its importance in the late development of the lungs.

Evolutionary developmental biologists categorize many different kinds of things, from ontogenetic stages to modules of gene activity. The process of categorization—the establishment of “kinds”—is an implicit part of describing the natural world in consistent, useful ways, and has an essentially practical rather than philosophical basis. Kinds commonly serve one of three purposes: they may function (1) as practical tools for communication; (2) to support prediction and generalization; or (3) as a basis for theoretical discussions. Beyond the minimal requirement that (...) classifications reflect biological reality, what sorts of kinds or classification will be useful in advancing a research program depends on the epistemological context. Thus, the important meaning of “natural” in “natural kinds” is not “natural with respect to nature,” but “natural with respect to the question.” This conclusion arises from the recognition that the proper role of concepts (e.g. natural kind, module, homology, model) is not to answer biological questions, but rather to help frame them. From a scientist’s perspective, arguing about the wording (or existence) of a single definition of “natural” or “kind” is beside the point: we get more work done by letting the question at hand determine what kinds of kinds are natural, on the basis of their ability to help answer it. We should be content to let “natural kinds” remain vague, multivalent, and–therefore broadly useful. For a philosopher like Hacking, the diverse, disparate, and ultimately incommensurable uses of the term “natural kind” have diluted its value so far that it loses all meaning. For practicing scientists, however, defining useful kinds in the context of particular questions and systems remains a productive epistemological strategy. (shrink)

The founding of the Carnegie Institute’s Department of Embryology in 1913, alongside its systematization of embryo staging, contributed to the mechanization of developmental stages of embryo growth in the early 20th century. For a brief period in the middle of the century, attention to the detailed interrelation between embryo development and time made pre-existing ideas about pregnancy ends less determinative of ideas about that developmental course. However, the turn to the genetic scale led to the disappearance of this attention, (...) replaced by a sense of biological life as seamlessly scripted. This study examines the history of what I refer to as temporal attention: attention to the live, unfolding potentialities within vital matter. The reintroduction of temporal attention to discussions of development allows us to more fully consider non-human vitality and the experiences of beings that house or otherwise intimately intersect with that vital tissue, regardless of outcomes.

The aim of this paper is to propose a systematic classification of emotions which can also characterize their nature. The first challenge we address is the submission of clear criteria for a theory of emotions that determine which mental phenomena are emotions and which are not. We suggest that emotions as a subclass of mental states are determined by their functional roles. The second and main challenge is the presentation of a classification and theory of emotions that can account for (...) all existing varieties. We argue that we must classify emotions according to four developmental stages: 1. pre-emotions as unfocussed expressive emotion states, 2. basic emotions, 3. primary cognitive emotions, and 4. secondary cognitive emotions. We suggest four types of basic emotions (fear, anger, joy and sadness) which are systematically differentiated into a diversity of more complex emotions during emotional development. The classification distinguishes between basic and non-basic emotions and our multi-factorial account considers cognitive, experiential, physiological and behavioral parameters as relevant for constituting an emotion. However, each emotion type is constituted by a typical pattern according to which some features may be more significant than others. Emotions differ strongly where these patterns of features are concerned, while their essential functional roles are the same. We argue that emotions form a unified ontological category that is coherent and can be well defined by their characteristic functional roles. Our account of emotions is supported by data from developmental psychology, neurobiology, evolutionary biology and sociology. (shrink)

A substantial body of theoretical literature testifies to the evolutionary functions of emotions. Relatively little has been written about their developmental functions. This article discusses the developmental functions of emotions from the perspective of differential emotions theory (DET; Izard, 1977, 1991). According to DET, although all the emotions retain their adaptive and motivational functions across the lifespan, different sets of emotions may become relatively more prominent in the different stages of life as they serve stage-related developmental processes. In the (...) first section, we present a brief overview of relevant aspects of the theory. In the second section, we discuss how emotions play a central role in helping the individual achieve developmental milestones and tasks during four major periods of life: Infancy, toddler through preschool years, middle to late childhood, and adolescence. The underlying thesis of this article is that emotions play a central role in stimulating social cognitive attainments at each stage of development. (shrink)

ALTHOUGH the nature of scientific explanation has been a topic much discussed by philosophers of science, one type of scientific explanation has received scant attention. In several of the sciences one often encounters a developmental explanation, an attempt, according to Woodward, "to explain why a system is in a certain stage of development by reference to a developmental 'law' which describes an orderly sequence of stages which systems of that kind go through.".

Development is a process whereby a relatively unspecified system comprised of loosely connected lower level parts becomes organized into a coherent, higher-level agency. Its temporal corollaries are growth, increasingly deterministic behavior, and a progressive reduction of developmental potential. During immature stages with relatively low specification and high potential, development is largely controlled by local interactions from the “bottom-up,” whereas during more highly specified stages with reduced potential, emergent autocatalytic processes exert “top-down” control. Robert Ulanowicz has shown that this (...) phenomenology of ascendency follows thermodynamic principles and can be described quantitatively using information theory, providing a general theory of development. However, the theory has not found a wide audience among developmental biologists, as genetic determinism encourages the popular reductionistic perception that ontogeny is controlled entirely by molecular mechanisms that exert efficient causality from the bottom-up. Nonetheless, measurements of metabolic rates and mRNA complexity in developing embryos, as well as functional analyses of gene regulatory systems, indicate that ontogeny fits the paradigm of developmental ascendency. Beyond informing biomedical research and the interpretation of large datasets obtained by systems-biological approaches, developmental ascendency helps explain the origin of life, and, being independent of scale, provides an overarching explanation for phylogenetic change that contextualizes Darwinian evolution.

Early childhood is characterized by many cognitive developmentalists as a period of considerable change with respect to representational format. Dienes & Perner present a potentially viable theory for the stages involved in the increasingly explicit representation of knowledge. However, in our view they fail to map their multi-level system of explicitness onto cognitive developmental changes that occur in the first years of life. Specifically, we question the theory's heuristic value when applied to the development of early mind reading and (...) categorization. We conclude that the authors fail to present evidence that dispels the view that knowledge change in these areas is dichotomous. (shrink)

Lewis describes the developmental core of dynamic systems theory. I offer recent data from developmental neuroscience on the sequential experience-dependent maturation of components of the limbic system over the stages of infancy. Increasing interconnectivity within the vertically integrated limbic system allows for more complex appraisals of emotional value. The earliest organization of limbic structures has an enduring impact on all later emotional processing.

The social function of language, as exemplified by “tonic communication,” is certainly not restricted to our own species. An individual's cognitive mastering of its environment, moreover, is equally essential for understanding the nature of any language. In the absence of comparative data, it is premature to claim that language skills at a particular developmental stage are uniquely human.

Ethical behavior — the conscious attempt to act in accordance with an individually-owned morality — is the product of an advanced stage of the maturing process. Three models of ethical growth derived from research in human development are applied to issues of business ethics.

While the genesis of self-awareness at approximately 18 months old is a dramatic landmark in human development, there is at this stage no explicit awareness on the toddler's part of his/her truly standing apart from others. Only much later does a distinct sense of self shift into focus, and here Sartre provides us with a compelling theory of a first reflective experience of self-awareness. He explains this phenomenon by emphasizing a violent shift in ontological status, one in which the pre-adolescent (...) child is precipitated from functional unity with a primary caregiver to an individuated state involving self-awareness as privative, i.e. where the child becomes aware of existing only in the form of not-being-the-adult. For Sartre this new experience of self is not therefore positive but rather formal or empty; there has in fact been a psychic transition, from being to nothingness. In addition, Sartre also states that all children first explicitly experience themselves in this fashion. These claims find support in the work of developmental psychologist Margaret Mahler. In fact, in spite of the vast developmental discrepancies between toddler and pre-adolescent child, given the appropriate environmental triggers privative subjectivity will be shown to involve a regression to the much earlier rapprochement stage of development described by Mahler.

Theoretical accounts of development exhibit several internal tensions and face multiple challenges. They span from the problem of the identification of the temporal boundaries of development (beginning and end) to the characterization of the distinctive type of change involved compared to other biological processes. They include questions such as the role to ascribe to the environment or what types of biological systems can undergo development and whether they should include colonies or even ecosystems. In this chapter we discuss these conceptual (...) issues, and we argue that adopting an organizational approach may help solve or clarify them. -/- While development is usually identified with the achievement of an adult form with the capability to reproduce and therefore maintain a lineage, adopting the organizational approach may provide a different strategy, which focuses also on the maintenance of the current organization of the organism. By doing so an organizational approach favors a switch in perspective which consists in analyzing how organisms maintain their viability at each moment of development rather than considering them as going through intermediate stages of a process directed toward a specific goal state. This developmental dimension of biological organization has yet to be given a general and detailed analysis within the organizational theoretical perspective, apart from some preliminary attempts. How a biological organization is maintained through a series of radical organizational changes and what these changes are issues that still require clarification. In this chapter we offer the beginnings of such an analysis of developmental transitions, understood as changes in functionality brought forth by regulatory mechanisms in the context of the continued maintenance of organizational viability at every step.

In Stages of Thought, Michael Barnes examines a pattern of cognitive development that has evolved over thousands of years--a pattern manifest in both science and religion. He describes how the major world cultures built upon our natural human language skills to add literacy, logic, and, now, a highly critical self-awareness. In tracing the histories of both scientific and religious thought, Barnes shows why we think the way that we do today. Although religious and scientific modes of thought are often (...) portrayed as contradictory-one is highly rational while the other appeals to tradition and faith-Barnes argues that they evolved together and are actually complementary. Using the developmental thought of Piaget, he argues that cultures develop like individuals in that both learn easier cognitive skills first and master the harder ones later. This is especially true, says Barnes, because the harder ones often require first the creation of cognitive technology like writing or formal logic as well as the creation of social institutions that teach and sustain those skills. Barnes goes on to delineate the successive stages of the co-evolution of religious and scientific thought in the West, from the preliterate cultures of antiquity up to the present time. Along the way, he covers topics such as the impact of literacy on human modes of thought; the development of formalized logic and philosophical reflections; the emergence of an explicitly rational science; the birth of formal theologies; and, more recently, the growth of modern empirical science. This groundbreaking book offers a thorough and persuasive argument in favor of the development of modes of thought across cultures. It will serve as an invaluable resource for historians of religion, philosophers and historians of science, and anyone interested in the relationship between religion and science. (shrink)

ABSTRACT Mindfulness is an umbrella term for a set of practices and strategies related to attention and non-critical awareness of our thoughts. Mindfulness is currently having a moment in popular culture and in clinical psychology for its many perceived benefits. However, there are reasons to worry about whether certain commitments and strategies of mindfulness might conflict with long-term progress in character development. This article places mindfulness in conversation with developmental considerations of virtue, asking how mindfulness practices might impact the various (...) stages between natural character and mature moral virtue in different ways. Moreover, it proposes a distinction between two kinds of virtues, presence and absence virtues, that are differently impacted by the continued use of mindfulness practices in the later stages of virtue development.

We present a developmental perspective regarding the difference in perceptions toward privacy between young and old. Here, we introduce the notion of privacy conceptions, that is, the specific ideas that individuals have regarding what privacy actually is. The differences in privacy concerns often found between young and old are postulated as the result of the differences found in their privacy conceptions, which are subsequently linked to their developmental life stages. The data presented have been obtained through a questionnaire distributed (...) among adolescents, young adults, and adults and provide support for this developmental perspective. This study is one of the first to include adolescents when investigating the privacy concerns among young and old. The results show that the privacy conceptions held by adolescents indeed differ from those held by young adults and adults in keeping with the expectations as seen from a developmental perspective. In addition, the areas in which the differences in privacy conceptions are found also reflect the strongest relationship with concerns. As such, these findings present an alternative perspective to the commonly held notion that young people are less concerned about privacy. (shrink)

Many biologists assume, as Darwin did, that natural selection acts mainly on late embryonic or postnatal development. This view is consistent with von Baer's observations of morphological divergence at late stages. It is also suggested by the conserved morphology and common molecular genetic mechanisms of pattern formation seen in embryos. I argue here, however, that differences in adult morphology may be generated at a variety of stages. Natural selection may have a major action on developmental mechanisms during the (...) organogenetic period, because this is when many adult traits are specified. Evolutionary changes in these early developmental mechanisms probably include subtle shifts in the timing of gene expression. Changes of this kind have little or no gross effect on the anatomy of the embryo; they are only phenotypically expressed, or readily detected, when amplified at later stages. The phylotypic stage, the developmental hourglass, modularity, and von Baerian divergence are reassessed in terms of these arguments. BioEssays 21:604–613, 1999. © 1999 John Wiley & Sons, Inc.

Infants' own activities create and actively select their learning experiences. Here we review recent models of embodied information seeking and curiosity-driven learning and show that these mechanisms have deep implications for development and evolution. We discuss how these mechanisms yield self-organized epigenesis with emergent ordered behavioral and cognitive developmental stages. We describe a robotic experiment that explored the hypothesis that progress in learning, in and for itself, generates intrinsic rewards: The robot learners probabilistically selected experiences according to their potential (...) for reducing uncertainty. In these experiments, curiosity-driven learning led the robot learner to successively discover object affordances and vocal interaction with its peers. We explain how a learning curriculum adapted to the current constraints of the learning system automatically formed, constraining learning and shaping the developmental trajectory. The observed trajectories in the robot experiment share many properties with those in infant development, including a mixture of regularities and diversities in the developmental patterns. Finally, we argue that such emergent developmental structures can guide and constrain evolution, in particular with regard to the origins of language. (shrink)

This article is an attempt to understand ethical theory not just as a set of well-developed philosophical perspectives but as a range of moral capacities that human beings more or less grow into over the course of their lives. To this end, we explore the connection between formal ethical theories and stage developmental psychologies, showing how individuals mature morally, regarding their duties, responsibilities, ideals, goals, values, and interests. The primary method is to extract from the writings of Kohlberg and his (...) students the cues that help to flesh out a developmental picture of a wide range of ethical perspectives. Thus, developmental psychology benefits from gaining a broader understanding of “morality” and “ethics,” and ethical theory benefits from a richer understanding of how moral maturity arises from youthful beginnings in juvenile and adolescent thinking. Results of this study offer insight into the difficulty of teaching ethics and a refined ability to assess moral maturity in business activity. (shrink)

In this study, we take up L. S. Vygotsky’s challenge to study learning and development in terms of categories, irreducible units that preserve the characteristics of the whole. One such category is experiencing [pereživanie], a process that integrates over the relation of person and environment. Using a case study from Iceland, we theorize the process of “becoming as a teacher-in-a-village school” in terms of experiencing [pereživanie]. The case describes a stage of development in the life of a person who becomes (...) a teacher and then experiences a developmental trajectory very different from his previous life as a fisherman. This is an aspect of teacher education that is hardly described in the teacher education literature which tend to be concerned with events after a person has entered a professional program or after a person has begun teaching. We discuss the implications of taking experiencing [pereživanie] as the developmental unit for theory and the practice of teacher education and development. (shrink)

Evolutionary developmental biology (or developmental evolution) is in the middle stages of its “development.” Its early ontogeny cannot be traced back to fertilization but pivotal developmental events included Gould’s (1977) treatment of heterochrony, Riedl’s (1978) analysis of “burden”, the Dahlem conference of 1981, a British Society of Developmental Biologists Symposium, as well as books that incorporated developmental genetics into older comparative themes. A major inductive process began with the discovery of widespread phylogenetic conservation in homeobox-containing genes. One interpretation of (...) these early developmental dynamics holds that an increasingly prominent problem agenda (e.g., how do novel structures and functions originate?), inherited from long-standing research programs in comparative embryology, morphology, and paleontology, was handed a powerful set of experimental tools from the lineage of experimental embryology. This allowed for an experimental probing of development and its evolution in an unprecedented fashion. Although the relationship between evolution and development has exhibited a protracted and complex history, we are still in the process of comprehending these early stages of “modern” EvoDevo’s ontogeny.

This cutting-edge book brings together eminent experts who propose ways to bridge cultural and developmental approaches to human psychology. The experts heed the call of cultural psychology to study different peoples around the world and to recognize that culture profoundly impacts how we think, feel, and act. At the same time, they also take seriously the developmental science perspective that humans everywhere share common life stage tasks and ways of learning. Doing what has not previously been done, the experts integrate (...) key insights and findings from cultural and developmental research. The result is a book brimming with new and creative syntheses for theory, research, and policy. This book is in step with a world where culturally diverse peoples interact with one another more than ever due to migration, worldwide media, and international trade and travel. With these interactions come changes to cultures and the psychological development of their members, and the implications for scholarship and policy are thoughtfully examined here. The book covers a wide range of related topics. It addresses the intersection of development and culture for psychological processes such as learning and memory, for key contexts of development such as family and civil society, for conceptions of self and identity, and for how the life course is partitioned including a focus on childhood and emerging adulthood.With its inclusion of diverse life phases, diverse topics, and experts from diverse disciplines and cultures, this volume speaks to a broad range of developmental and cultural issues. The synthesis of cultural and developmental approaches should be exciting and eye-opening to anyone with an interest in human psychology in today's global world. (shrink)

Our visual environment is highly predictable in terms of where and in which locations objects can be found. Based on visual experience, children extract rules about visual scene configurations, allowing them to generate scene knowledge. Similarly, children extract the linguistic rules from relatively predictable linguistic contexts. It has been proposed that the capacity of extracting rules from both domains might share some underlying cognitive mechanisms. In the present study, we investigated the link between language and scene knowledge development. To do (...) so, we assessed whether preschool children with Developmental Language Disorder, who present several difficulties in the linguistic domain, are equally attracted to object-scene inconsistencies in a visual free-viewing task in comparison with age-matched children with Typical Language Development. All children explored visual scenes containing semantic, syntactic, or both inconsistencies. Since scene knowledge interacts with image properties to guide gaze allocation during visual exploration from the early stages of development, we also included the objects’ saliency rank in the analysis. The results showed that children with DLD were less attracted to semantic and syntactic inconsistencies than children with TLD. In addition, saliency modulated syntactic effect only in the group of children with TLD. Our findings indicate that children with DLD do not activate scene knowledge to guide visual attention as efficiently as children with TLD, especially at the syntactic level, suggesting a link between scene knowledge and language development.

Martin Leichtman's _The Rorschach_ is a work of stunning originality that takes as its point of departure a circumstance that has long confounded Rorschach examiners. Attempts to use the Rorschach with young children yield results that are inconsistent if not comical. What, after all, does one make of a protocol when the child treats a card like a frisbee or confidently detects "piadigats" and "red foombas"? A far more consequential problem facing examiners of adults and children alike concerns the very (...) nature of the Rorschach test. Despite voluminous literature establishing the personality correlates of particular Rorschach scores, neither Hermann Rorschach nor his intellectual descendants have provided an adequate explanation of precisely what the subject is being asked to do. Is the Rorschach a test of imagination? Of perception? Of projection? In point of fact, Leichtman argues, the two problems are intimately related. To appreciate the stages through which children gradually master the Rorschach in its standard form is to discover the nature of the test itself. Integrating his developmental analysis with an illuminating discussion of the extensive literature on test administration, scoring, and interpretation, Leichtman arrives at a new understanding of the Rorschach as a test of representation and creativity. This finding, in turn, leads to an intriguing reconceptualization of all projective tests that clarifies their relationships to more objective measures of ability. (shrink)

In this original work of psychoanalytic theory, John Muller explores the formative power of signs and their impact on the mind, the body and subjectivity, giving special attention to work of the French psychoanalyst Jacques Lacan and the American philosopher Charles Sanders Peirce. Muller explores how Lacan's way of understanding experience through three dimensions--the real, the imaginary and the symbolic--can be useful both for thinking about cultural phenomena and for understanding the complexities involved in treating psychotic patients. Muller develops Lacan's (...) perspective gradually, presenting it as distinctive approaches to data from a variety of sources, such as cognitive, social and developmental psychology, literature, history, art, and psychoanalytic treatment. The book's first four chapters present Muller's reading of selected data from child development research, psychology and linguistics, approximating a semiotic model of "normal" development. The following three chapters examine in a Lacanian framework the structural basis of psychotic stages as indicative of massive semiotic failure in development. The final chapters on human narcissism suggest reasons that "normal" development may be impossible. (shrink)
