"Beyond Nature vs. Nurture: Changing views of infant language development"
Long before infants produce their first words, they have learned a tremendous amount about their native language(s). What do infants know, and how did they learn it? Ground-breaking research is fundamentally changing how we understand early language development. Evidence will be presented indicating that infants learn some aspects of language by tracking its statistical properties. Implications for atypical language development will also be considered.

"How We Integrate New Information with Existing Knowledge: A Complementary Learning Systems Analysis"
Some years ago, two colleagues and I described a complementary learning systems theory of the roles of hippocampus and neocortex in memory (McClelland, McNaughton, & O'Reilly, 1995). Our theory postulated that rapid integration of arbitrary new information into neocortex is avoided to prevent catastrophic interference with existing knowledge structures. In this talk, I examine evidence from recent studies that new information can sometimes be integrated rapidly into the neocortex, challenging our theory as previously presented. I present new simulations based on our theory, showing that new information that is consistent with knowledge previously acquired by our putatively cortex-like artificial neural network can be learned rapidly without interfering with existing knowledge. It is when/ inconsistent/new knowledge is acquired quickly that catastrophic interference ensues. These results match the pattern observed in the recent studies, and provide a mechanism for understanding when and how rapid integration of new information occurs.

"The Dynamics of Learning and Attention in Infants and Adults"
Over the past two decades, there has been substantial interest in a powerful implicit learning mechanism - often called statistical learning - that enables infants, children, adults and non-humans to extract patterned information by mere exposure to structured input. A key question is how learners go beyond the input they receive to make implicit inferences about novel exemplars they have never encountered - i.e., when to generalize and when to treat new items as exceptions. A corollary of this question is how learners adapt to a changing environment - i.e., how do they build a model of the world that contains more than a single structure? A second key question is how naive learners make implicit inferences about which features of the input are most likely to be informative - how to guide attention among a large set of alternatives. I will summarize a series of experiments with infants, children, and adults that address these two questions and highlight additional challenges faced by learners in natural (complex) environments.

"The Origin of Concepts: A Case Study of Natural Number"
A theory of conceptual development must specify the innate representational primitives, must characterize the ways in which the initial state differs from the adult state, and must characterize the processes through which one is transformed into the other. I will defend three claims: 1) With respect to the initial state, the innate stock of primitives is not limited to sensory, perceptual, or sensory-motor representations; rather, there are also innate conceptual representations. 2) With respect to developmental change, conceptual development consists of episodes of qualitative change, resulting in systems of representation that are more powerful than, and sometimes incommensurable with, those from which they are built. 3) With respect to a learning mechanism that achieves conceptual discontinuity, I offer Quinian bootstrapping.

"Event Knowledge and Sentence Processing: A Blast from the Past"
Language processing has often focused on how language users comprehend and produce sentences. Although fluent use obviously requires integrating information across multiple sentences, the syntactic and semantic processes necessary for comprehending sentences have (with some important exceptions) largely been seen as self-contained. That is, it was assumed that these processes were largely insensitive to factors lying outside the current sentence's boundaries. This assumption is not universally shared, however, and remains controversial. In this talk, I shall present a series of experiments that suggest that knowledge of events and situations—often arising from broader context—plays a critical role in many intrasentential phenomena often thought of as purely syntactic or semantic. The data include findings from a range of methodologies, including reaction time, eye tracking (both in reading in the visual world paradigm), and event-related potentials. The timing of these effects implies that sentence processing draws in a direct and immediate way on a comprehender's knowledge of events and situations (or, the "blast from the past", on knowledge of scripts, schemas, and frames).

"Words and Dinosaur Bones: Knowing About Words Without a Mental Dictionary"
For many years, language researchers were not overly interested in words. After all, words vary across language in mostly random and unsystematic ways. Language learners simply had to learn them by rote. Words were uninteresting. Rules were where the exciting action lay, and considerable effort was invested in trying to figure out what the rules of languages are, whether they come from a universal toolbox, and how language learners could acquire them. Over the past decade, however, there has been increasing interest in the lexicon as the locus of users' language knowledge. There is now a considerable body of linguistic and psycholinguistic research that has led many researchers to conclude that the mental lexicon contains richly detailed information about both general and specific aspects of language. Words are in again, it seems. But this very richness of lexical information poses representational challenges for traditional views of the lexicon. In this talk, I will present a body of psycholinguistic data, involving both behavioral and event-related-potential experiments, that suggest that event knowledge plays an immediate and critical role in the expectancies that comprehenders generate as they process sentences. I argue that this knowledge is, on the one hand, precisely the sort of stuff that on standard grounds one would want to incorporate in the lexicon but, on the other hand, cannot reasonably be placed there. I suggest that, in fact, lexical knowledge (which I take to be real) may not properly be encoded in a mental lexicon, but through a very different computational mechanism.

"Why We're So Smart"
Human cognitive abilities are remarkable, and even more remarkable is the the rapidity with which children develop cognitive insight. How does this insight arise? A pervasive view in cognitive development is that these rapid gains can only be explained by assuming that infants begin with substantial amounts of innate knowledge. In this talk I propose an alternative approach, centered on mechanisms of human learning. I suggest two powerful forces that contribute to human learning and reasoning ability: (1) analogical processing; and (2) the acquisition of relational language. I will present evidence that the structure-mapping processes that occur during analogy and similarity are a core mechanism by which abstract knowledge arises from experience. Our studies of learning in adults and children show that analogical comparison processes foster learning in several ways: by aligning common relational structure, by suggesting inferences between situations, by focusing attention on relevant differences, and by inviting relational abstractions.
A further contributor to human learning and reasoning is the acquisition of relational language. Relational language provides labels that preserve and systematize the relations discovered through comparison processes. It also acts to invite analogical comparisons that reveal common structure. In sum, I suggest that mutual bootstrapping between structure-mapping processes and relational language is a major contributor to human cognition.
Dedre Gentner’s (Department of Psychology, Cognitive Science Program, Northwestern University) research is on the psychology of learning and reasoning and the development of cognition and language. Her early work on causal mental models and on the development of word meaning have been influential in cognitive research. Her most important contribution is the structure-mapping theory of analogy and similarity and its implications, including a computational model of similarity processing; a theoretical framework for analogy and metaphor; the evidence for disassociation between the kind of similarity that governs memory retrieval and the kind of similarity that governs on-line mapping and inference. In her developmental work she has proposed a relational shift in children’s similarity processing and has found evidence that this shift is knowledge-driven, rather than maturational. She has also proposed and tested a progressive alignment mechanism whereby comparison processes in ordinary experience can yield theoretical insight.
In language learning, Gentner’s hypothesis of a language-universal advantage for nouns in children’s early word learning that has engendered considerable research. Her recent work unites analogical thinking and language learning and investigates possible interactions between language and cognition. Her theoretical and empirical work provides evidence that relational language has a formative role in the development of relational thought. She is also investigating the hypothesis that analogical processes are integral to language acquisition and use.

"Conceptual Perspective of Speaker Choices"
Adult speakers choose among perspectives when they talk; they use different terms to pick out different perspectives (e.g., the dog, our pet, that animal). The perspectives adult speakers adopt affect how they both categorize and remember events. Yet studies of lexical acquisition in young children have often proposed a single-perspective view that assumes children can at first use only one term for talking about a referent object or event: a cat can only be called "cat", not "animal" or "Siamese" as well. But since children are exposed to multiple perspectives by the adults around them, it seems reasonable that they too should adopt alternative perspectives from an early age--the many-perspectives view. Moreover, adults offer children pragmatic directions about the meanings of new words and hence about new perspectives. Evidence for this many-perspectives account comes from a range of sources: children spontaneously use more than one term for the same object; they construct novel words to mark alternate perspectives; they shift perspective when asked; and they readily learn multiple labels for the same referent.
Eve V. Clark, Professor of Linguistics & Symbolic Systems at Stanford University, grew up and was educated in the UK and France. After completing her PhD in Linguistics with John Lyons at Edinburgh, she worked on the Language Universals Project at Stanford with Joseph Greenberg, and two years later, joined the Linguistics Department at Stanford University. She has taught there since, aside from several years 'off' in the UK and the Netherlands. She has been a Fellow at the Center for Advanced Study in the Behavioral Sciences, Stanford (979-1980) and a Guggenheim Fellow (1983-1984); she is a Fellow of the American Association for the Advancement of Science, and a member of the Royal Netherlands Academy of Sciences. Her research has focused on first language acquisition, in particular on the acquisition of meaning, where she has done extensive observational and experimental research; she has also worked the acquisition and use of word-formation, with detailed comparative studies of English and Hebrew in children and adults, and she has explored the pragmatics of word-coinage, applying the principles of conventionality and contrast to language use as well as to the process of acquisition. In her most recent work, she has been looking at the kinds of information adults offer children about unfamiliar words and their meanings, at the amount of negative evidence children may receive in the course of conversation, and at the relative contributions of gesture and gaze vs. language in adult exchanges with one- and two-year-olds. She has published numerous articles and chapters in linguistics and psycholinguistics. She is co-author of Psychology and Language (1977), and author of The Ontogenesis of Meaning (1979), Acquisition of Romance, with special reference to French (1985), The Lexicon in Acquisition (1993), and, most recently, First Language Acquisition (2003).

"How We Reason"
A long-standing tradition postulates that human thinking is rational because it is founded on the 'laws of thought'. This talk argues to the contrary that reasoning is not based on such laws, but on the ability to envisage possibilities. A conclusion is judged to be valid if it holds in all such MENTAL MODELS of the given information, and probable if it holds in most of them. This theory is based on three main principles: each mental model represents a possibility; the structure of models corresponds to the structure of what they represent; and models normally represent only what is true. The talk outlines the evidence corroborating the theory from behavioral and brain-imaging studies. Inferences from one model are easier than inferences from multiple models. Knowledge affects the process of reasoning. And, if falsity matters, reasoners commit systematic fallacies. Humans are not always rational, but they are not intrinsically irrational, either.

"Possible Stages in the Evolution of the Language Faculty"
The human ability to learn language is a human cognitive specialization, encoded (in some unknown way) in our genes. The evident adaptivity of linguistic communication suggests that this capacity arose through natural selection. It is therefore a challenge for linguistics to find a plausible route by which the features of language could have evolved step by step. I will propose such a route, using evidence from child and adult language acquisition, from aphasia, from pidgin and creole languages, from "language"-trained apes, and from "fossils" of earlier forms of the language capacity still found in modern-day languages.

"Human Brains: The Difference that Makes the Difference
Within the divergent structures of human brains lie the clues to our most unique human abilities: from language to esthetic appreciation. By exploring how human brains structurally diverge from patterns common to other primate and mammal brains we can find hints about which brain differences make the difference. But there are many differences. How do we know which ones matter most? In this presentation I will review some of the evidence concerning these differences, the mechanisms underlying them, and their implications for language functions. By investigating the ways that neurodevelopmental processes have been modified in humans, I will show that our unique abilities have not been produced by the addition of new structures, but rather from subtle modifications of existing primate brain systems. Looking more closely at some of these modifications to the "standard primate brain plan" we find that they correspond closely with some of the most unusual neural demands that are imposed by language processing. Three of these neural adaptations to language are explored: the neural bases for symbolic, vocal, and syntactic abilities. Using these insights I will suggest ways to clear up some confusions about what must be innate and why (or why not), and suggest some unexpected new ways to think about how languages and brains have co-evolved in our prehistory.

"Education the Human Brain: A View from the Inside"
The methods of neuroimaging allow examination of the normal human brain in the process of acquiring and executing such high level skills as reading calculating and retrieving facts. By combining use of high density electrical recording and changes in cerebral blood flow we can examine the anatomy of these skills in real time. Some skills are acquired very slowly. The area of the brain that synthesizes visual letters into a unified word develops very slows over years of acquiring the skill of reading. Once developed it is resistant to change. On the other hand, semantic information about words is acquired rapidly and is easily automated. Surprisingly, access to the number line in mental calculation appears similar in five year olds and adults. Acquisition of new information can influence performance either implicitly, without awareness of the subject, or explicitly through deliberate reference to past experience. In our studies we observe the tie course of the operation of these conscious and unconscious learning mechanisms.
"Cognitive Neuroscience and Brain Plasticity"
Cognitive neuroscience has uncovered a vast array of brain mechanisms related to such psychological phenomenon as strategies, priming, item learning, concept learning and development. Research will undoubtedly refine and enlarge our current views We can discuss possible research strategies we are taking in our Institute. We can consider how these findings might influence cognitive science and the strategies to to use these new finding for teaching, rehabilitation, and therapy.

"Development of Attentional Networks for Regulating Thought, Feeling, and Behavior"
A major goal of cognitive neuroscience is to link behavior to neural systems. Much of our behavior depends upon the direction of attention. In laboratory task s when we choose among conflicting stimuli, monitor and correct errors or respond to novel events there is activity in the frontal midline (anterior cingulate) that appears to serve the function of regulating information flow. This same general area responds both to the subjective experience of pain and to individual differences in emotional awareness. In early infancy a major behavior problem is the control of distress which we believe involves the anterior cingulate. Three to five year olds, learning to regulate information flow in cognitive tasks, may activate areas of the cingulate because parts of this brain area are already involved in self regulation. Congruent with this view tasks involving the control of conflict are correlated with the ability to inhibit responses and with parental reports of attentional control and self regulation.

"Constructing Spatial Semantic Categories: A Crosslinguistic Perspective"
Semantic development is often viewed as a process of mapping between linguistic forms encountered in the speech input and concepts established through universally shared patterns of cognitive development; e.g., children learn the word IN to express a fundamental spatial notion of "containment". This characterization is challenged by recent crosslinguistic research. Evidence will be presented that languages differ strikingly in their semantic structuring of even such basic conceptual domains as space, and that children begin to home in on language-specific classification principles remarkably early, by two years of age or before. But if children's early word meanings are not completely nonlinguistic, nor are they completely shaped by language -- there is a complex interaction between the influence of the input language and learners' nonlinguistic conceptual predispositions. Mechanisms that might underlie this interaction will be considered.
Melissa Bowerman has researched and published widely on topics in first language acquisition ranging from syntax and morphology to word meaning and phonology. Recurrent themes in her work include the relationship between conceptual development and language development, the use of crosslinguistic comparisons to disentangle what is universal and possibly innate from what is learned, the nature of children's early linguistic rules, and the potential of information about language acquisition to help decide among alternative theoretical approaches to language structure. Her most recent work focuses on the acquisition of argument structure alternations, and on the classification of topological spatial relationships by languages and by language learners.

"Learning and Interactive Multimedia"
Educational systems are in need of radical change. One way to achieve this change is to create new teaching devices. By attempting to build intelligent computers, we have learned a great deal about how people learn. By putting this knowledge about human learning to use in designing computer-based educational programs we can create effective teaching devices for the future. The key aspect of computer-based learning environments is their ability to allow students to learn by doing. Computers can place students in new, different and interesting environments where they can direct their own learning, following their own interests and achieving goals they set for themselves. Most importantly, these environments can include large libraries of stories, on video, told by experts in particular fields. The student can hear these stories, and learn from them, at just the moment in their own work when they most need help. The programs should be designed around particular learning goals of students, creating scenarios where students are motivated to accomplish tasks that lead to successfully attaining the goals in question. Such goal based scenarios can be used for any subject matter, for any age student, in schools or in business. These programs change what students are learning as well as how they are learning. Students learn how to actually do things rather than simply memorizing isolated factual material.

"Concepts of Self"
What can be learned from a close analysis of how people "tell" about Self in different settings for different ends? How do we "map" these "tellings" on the folk construct of Self and how shall we develop our psychological constructs of Self to take account of both the "tellings" and the folk constructs? I will examine the possibility of considering Self as the central protagonist in a set of partially connected narratives that represent the relationship between Self and Others and Self and a world codified symbolically as "outside" Self- Other relationships. This is the system that yields an overall (but open) relationship between Self-Other, Culture, and Nature.
