Title: Can robots invent their own language, and what can we learn from this about human language evolution?
Abstract: For more than a decade we have been doing robotic experiments to understand how language could originate in a population of embodied agents. This has resulted in various fundamental mechanisms for the self-organisation of vocabularies, the co-evolution of words and grounded meanings, and the emergence of grammar. It has also lead to a number of technological advances in language processing technologies, in particular a new grammar formalism called Fluid Construction Grammar, that attempts to formalise and capture insights from construction grammar, and a new scheme for doing grounded semantics on robots. This talk gives a (very brief) overview of our approach and discusses the relevance for theories of human cultural evolution in general and language in particular. The talk is illustrated with live software demos and videos of robots playing language games.

Title: Human sensorimotor coordination: a moving, gripping and occasionally tapping story
Abstract: Successful coordination involves the movement of various segments of the body that have to be controlled in a systematic and meaningful way. Studying how the brain puts together these movements involves a good understanding of the interaction between sensory information, cognitive processes and motor control. In this talk I will present recent work from my laboratory on sensorimotor coordination in the context of sequential tasks. Acts such as playing the piano, involve the repetitive movement of certain effectors (wrist, finger, arm) with respect to external events such as a metronome, a complex musical score and even the movements of other actors/musicians. From studying the timing aspect of these behaviors we can understand 1) how the brain organizes sequential movements 2) how rhythmic structures can be entrained and instantiated in individual and social contexts and 3) how rhythmic sequences are learned and encoded. In this talk, I will bring together evidence from neurophysiological and behavioral experiments in presenting a coherent view of the human sensorimotor coordination.

Title: Memory as communication
Abstract: Memory can be seen as communication between stages - communication between an earlier and a later self. This idea only becomes more than a loose analogy, though, if there is a theory of communication that can add something substantial to our understanding of memory. I'll argue that recent models of communication, developed for quite different applications, can indeed play this role. Application of these ideas to memory can inform debates about the 'reconstructive' nature of memory, the function of episodic memory, and the relations between memory in genetic, epigenetic, and neural systems.

Title: Beyond Nature versus 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? In this talk, I will describe results from multiple lines of research that suggest that infants track statistical properties of language, and use this information for myriad aspects of language acquisition. Implications for atypical language development will also be considered.
Presenter: Justin Halberda, Psychological and Brain Sciences, Johns Hopkins University
Title: Interfaces: Number and math abilities; Visual attention and word meanings
Abstract: Our field has made terrific progress by studying cognitive systems in isolation from each other (e.g., a Theory of Mind Module, a Language Acquisition Device) - yet, we all acknowledge that the mind-body is a single integrated and unified machine. One way of addressing the challenges of charting this unification is by characterizing how various cognitive systems interface with each other. In this talk, I highlight two cases of interface: One between early mathematical cognition and formal math abilities, and another between the constraints of mid-level visual processing and lexical meanings. The goal is to demonstrate some of the surprising dependencies we've discovered between these systems, and to highlight how such dependencies may transform how we understand the systems involved.

Title: Anxiety, fear conditioning and decision making under threat of shock.
Abstract: The ability to track and update stimulus-stimulus and action-outcome contingencies is central to both the acquisition and extinction of conditioned fear and to reinforcement learning. While the fear conditioning literature has focused on the acquisition and over-writing of neutral stimulus (CS) - negative stimulus (UCS) associations, the decision-making literature has primarily investigated the effects of varying schedules of reward. There is however evidence that anxiety is not only linked to enhanced acquisition, maintenance and generalization of conditioned fears but also to altered decision-making. The work presented examines the extent to which trait vulnerability to anxiety is associated with disruption to associative learning, both using classical Pavlovian fear conditioning and a 2-arm bandit task requiring decision making under threat of shock. FMRI and pupillometry are used to characterize the mechanisms disrupted. In addition, traditional models from the reinforcement learning literature are combined with more recent Bayesian approaches to address the extent to which similar mechanisms underlie decision-making under threat as decision-making under conditions of varying probabilities and magnitudes of reward and to examine the aspects of decision making altered in high trait anxious individuals.

Title: Best explanations, Bayes's rule, and bonus points
Abstract: Bayesianism and Explanationism both offer theories of uncertain inference. The former uses probabilities to represent people's credences, and it associates particular inferences with the shifts in credence explicated by Bayes's Theorem as the differences between prior and posterior probabilities. Explanationism puts explanatory considerations at the center of certain cases of uncertain inferences by interpreting these as inferences to hypotheses judged to be the best explanations of the evidence. But how do these two theories relate to one another? Do they constitute competing theories? When people reason to the best explanation of the evidence before them, how often and how closely - if at all - do they approximate the shifts in credence predicted by Bayesianism? In this talk, I explore these questions, drawing upon ongoing experimental work as well as recent work in formal epistemology.
