Culturally Motivated Remembering

Episodic memory involves remembering specific events from a particular time and place and their details. It enables us to mentally travel back in time to re-experience our past and is regarded as a true marvel of nature. I discuss how this fundamental process of remembering is variably motivated across cultures. I present findings to show that the culturally motivated process is reflected in the functional significance of episodic memory in constituting the self. It takes place at different stages of remembering and is sustained by family mnemonic practices. The culturally motivated process further moderates the effects of “universal” mechanisms and shapes the psychological consequences of remembering. By delineating the culturally motivated process of remembering, I illustrate that episodic memory may well reflect the adaptive nature of human cognition in response to the specific ecological environment and social context in which individuals reside.

Me and My Shadow:

The Conscious Mind, the Auxiliary Mind,How They Cooperate, and How They Grow

This talk will address one of the mysteries of human behavior, the contrast between the very small limit in how much information can be held in the conscious mind at once and the broad capabilities that we all display when using language and solving problems. To explain this paradox, a major premise to be examined is that the conscious mind has an auxiliary helper, or shadow, in the form of ready-to-use memory information relevant to the task at hand but just outside of the focus of attention or conscious awareness. The parameters of the interaction of these conscious and auxiliary facets of the mind will be discussed with respect to research on adult working memory, brain function, and child development.

Towards a Cognitive Neuroscience of Modal Cognition

In philosophy, the term "modality" refers to the different ways or modes in which things could be. Some things are necessary, some things are possible, and some things are impossible. There are also different kinds of possibility. Some things are physically possible but biologically impossible, for instance, or logically possible but physically impossible. Understanding the boundaries between what is necessary, possible, and impossible is a difficult task, and a large number of logicians, metaphysicians and epistemologists have endeavor their careers to clarify this difficult issue. In this talk I hope to show that cognitive psychology and neuroscience can contribute to this ongoing and fascinating research by uncovering the neural and cognitive mechanisms underlying certain kinds of modal judgments. In particular, I hope to show that thoughts about alternative ways in which the past could, should, or would have been draw resources from different memory systems depending on certain features of the counterfactual content, such as the perceived likelihood of the counterfactual event, or whether or not the counterfactual involves a person one is familiar with. My hope is to show that modal cognition is a promising and highly interdisciplinary area of research in cognitive neurophilosophy.

Social Transmission of Information & Emergence of Collective Memory

Influence of Cognitive Mechanisms & Network Structures

Shared stories are the glue of our social lives. As social animals, people spend a majority of their lives sharing and remembering experiences with others.  Couples, friends, families, study groups, work teams, and even members within communities and societies develop shared memories to fulfill a variety of personal, social, educational, and political goals. The emergent collective memories - memories that people within such networks come to share about their past - have long been topics of interest in the domains of history, anthropology, sociology, and social psychology.  In cognitive science, tracing back to Bartlett's seminal treatise in 1932, there has been a long-standing interest in the transmission of memory in social settings.  However, a century of research on memory has almost exclusively focused on individuals working in isolation. The last decade marks a departure in this context, with a rapidly growing focus on the study of how people remember in groups and how social sharing reciprocally shapes the post-collaborative memory of each conversational partner. I will review data and theory from my lab to elucidate the cognitive mechanisms that underlie memory enhancement as well as forgetting in shared remembering, the influence of the structure of the social network on memory propagation, and the cascading effects of these changes on the emergence of collective memory. Together, these empirical and theoretical advances provide the scientific tools for exploring the wide-ranging influences of social transmission of memory and the emergence of collective memory.

Neural Mechanisms for Naturalistic Sentence Comprehension: EEG & MEG Evidence

This talk addresses the brain bases of sentence comprehension in everyday contexts, such as when listening to a story. By combining computational accounts of parsing with explicit linking hypotheses, we model high-dimensional EEG and MEG data from naturalistic experiments. These neurocomputational models are brought to bear on three psycholinguistic issues: the role of abstract hierarchical structures during everyday listening; the algorithm implemented by brain regions that process sentence structure; and predictive sentence processing in individuals with and without Autism Spectrum Disorder.

New Perspectives on the Brain Mechanisms of Attention

William James famously said, “Everyone knows what attention is.” We also know a lot about how the brain controls attention: most evidence points to a network of areas in the cerebral cortex, with frontal and parietal cortex regulating limited resources available in the sensory areas of cortex. However, this is not the complete picture. Subcortical brain regions also play a role in attention; in this talk I will explain how our study of a particular subcortical brain region, the superior colliculus, has led us to a very different view of attention. We have found that not only does the superior colliculus play a crucial role in the control of spatial attention, it appears to do so through mechanisms that are dissociable from the well-known mechanisms in sensory cortex.

These findings have led us to propose that attention is not primarily a sensory processing bottleneck, but is instead a by-product of downstream decision-making steps. We are testing these ideas using a combination of electrophysiology, functional imaging, and optogenetic approaches, and our new results support the perspective that the brain mechanisms for attention are centered on an evolutionarily conserved subcortical decision-making circuit that predates the emergence of the neocortex.

Going Beyond the Given: Generation of New Knowledge in the Lab & in the Classroom
Building a knowledge base is one of the most important tasks in development and education. Formal and informal educators alike go to great lengths to impart information to learners. Yet for learning experiences to have their maximum impact, learners must go beyond what is directly given to them to generate novel understandings and innovations, the currencies of academic, as well as, vocational success. Extensive research has examined a generation of novel understandings through different forms of reasoning, including analogy, deduction, and induction. Yet attention to how productive processes operate over information acquired in different learning episodes, separated by time, modality, or medium, is only beginning to be understood.

The focus of the talk will be new research on the productive process of self-generation of new knowledge through integration of separate episodes. Data from preschool-age children, school-age children, and college-age adults will be presented. The data establish the phenomenon of self-generation through integration. Work using behavior, eye tracking, and event-related potentials (ERPs) has revealed some of the cognitive processes involved. Individual differences in self-generation through integration relate to academic achievement, prompting translation of the research into classroom settings, including elementary education models in which information is presented in different languages, requiring integration across different surface forms, a challenge in most productive extension paradigms.

The Now-or-Never Bottleneck: A Fundamental Constraint on Language
Language happens in the here-and-now. Our memory for linguistic input is fleeting. New material rapidly obliterates previous material. How then can the brain deal successfully with the continual deluge of linguistic input? I argue that, to deal with this “Now-or-Never” bottleneck, the brain must incrementally compress and recode language input as rapidly as possible into increasingly more abstract of levels of linguistic representation. This perspective has profound implications for the nature of language processing, acquisition, and change. Focusing on language acquisition, I present a computational model that learns in a purely incremental fashion, through on-line processing of simple statistics, and offers broad, cross-linguistic coverage while uniting comprehension and production within a single framework. The model achieves strong performance across over 200 single-child corpora representing 29 languages from the CHILDES database. I conclude that the immediacy of language processing provides a fundamental constraint on accounts of language acquisition, implying that acquisition fundamentally involves learning to process, rather than inducing a grammar.

Prefrontal Cortex and the Hierarchical Control of Behavior
This talk will describe a recent line of research in our lab investigating the cognitive and neural systems that support hierarchical cognitive control, or our ability to simultaneously control immediate actions while also holding more abstract, temporally remote goals in mind. Psychologists have long proposed that we have a capacity for hierarchical control, citing its potential contributions to sequential behavior, as well as higher-order planning, reasoning, and abstraction. Despite its importance for cognition, the cognitive and neural mechanisms that support hierarchical control remain unknown. Here I will provide evidence that this type of complex control could arise through elaboration of the simple corticostriatal motor circuit.

Human Evolution in the Plio-Pleistocene: A World Queerer than We Supposed
The evolution of the human capacity for adaptation via cumulative cultural evolution is a major macroevolutionary puzzle. Beginning about 2 million years ago our lineage began to evolve our very large brain. At least two of the things our brain includes are a uniquely sophisticated system of social learning and social psychology that facilitates cooperation with nonrelatives. In the Holocene, humans have undergone a massive adaptive radiation based on cultural adaptations that have made us the earth’s ecologically dominant species. Most similar “killer adaptations,” such as the camera-type eye and internal skeleton of vertebrates, evolved hundreds of millions of years ago. The default, often unarticulated, hypothesis to explain the late emergence of cumulative culture is that it requires complex reorganizations of the brain, and perhaps other features of the basic vertebrate body plan to achieve. Hundreds of millions of years transpired before the critical final reorganization occurred in our species.

Another possible explanation is that the big brain and extended life history required to sustain cumulative culture is quite costly. Only an environment in which the payoff to cumulative culture is unusually high will favor its evolution. In the last few decades we have learned from ice, lake, and ocean cores that climates have gotten colder, drier, and more variable in space and time over the last 50 million years. With the onset of the Plio-Pleistocene glacial system climates became especially variable, albeit mostly on time scales too long to favor cumulative culture. High-resolution cores began to be recovered and published in the 1990s. They revealed that the last ice age included large amounts of climate variation on century to millennial time scales. These are the time scales that theoretical models suggest can favor a costly system of cumulative culture. In the last decade, longer high-resolution cores suggest that the amount of high-frequency variation has progressively increased over the last several 100,000-year glacial cycles, roughly paralleling increases in human brain size and the increases in sophistication of stone tools. We cannot reject the hypothesis that the human capacity for cumulative culture evolved in the Plio-Pleistocene in direct response to high and rising environmental variation. The expansion of Anatomically Modern Humans out of Africa occurred near the onset of an especially variable part of the last ice age. Agriculture, the economic basis for our Holocene dominance, began to evolve when the intense millennial and submillennial scale variation stopped.

Small-World Networks in Science & Society
Everyone is familiar with the small-world phenomenon: soon after meeting a stranger, we are often surprised to discover that we have a mutual friend or that we are linked by a short chain of friends. In this talk, I’ll present evidence that the small-world phenomenon is more than a curiosity of social networks — it is actually a general property of many networks found in nature and technology, ranging from nervous systems to the power grid and the Internet. I’ll also speculate about some of the broader implications of these findings (e.g., for the spread of infectious diseases), and will reveal the identity of the actor at the center of the Hollywood universe (it’s not Kevin Bacon).

Neural Representations of Language Meaning
How does the human brain use neural activity to create and represent meanings of words, sentences, and stories? One way to study this question is to have people read text while scanning their brain, then develop machine learning methods to discover the mapping between language features and observed neural activity. We have been doing such experiments with fMRI (1 mm spatial resolution) and MEG (1 msec time resolution) brain imaging for over a decade. As a result, we have learned answers to questions such as, Are the neural encodings of word meaning the same in your brain and mine? Are neural encodings of word meaning built out of recognizable subcomponents or are they randomly different for each word? What sequence of neurally encoded information flows through the brain during the half-second in which the brain comprehends a single word or when it comprehends a multiword sentence?

Reanalysis and Limited Repair Parsing in Neural Networks
In his paper “Reanalysis and limited repair parsing: Leaping off the garden path”, Lewis (1998) presented a computational account to Fodor & Inoue’s (1994) diagnosis model for syntactic garden path theory (Frazier 1987). In my presentation I shall demonstrate how the discrete states of Lewis’ (1998) symbolic repair parser can be represented by activation vectors of a neural network that are connected through heteroclinic sequences in continuous time (Rabinovich et al. 2008, beim Graben & Potthast 2012). In this picture, encountering a garden path corresponds to an undesired fixed point attractor that has to be destabilized by a bifurcation in course of diagnosis processes. Leaping off the garden path is then described by a change of the network’s control parameters reflecting the syntactic processing strategy (beim Graben et al. 2004, Kiebel et al. 2009).

Numerical Thinking
Many of the important decisions that we make in life require dealing with numbers. Individuals, however, often struggle to understand and properly use numbers, which can lead to distorted decisions. I explore the psychology of numerical thinking using evidence from marathon runners, car buyers, SAT takers, baseball players, and house buyers.

Broca’s Area and the Evolution of Language
Several areas of the brain important to language appear to have undergone significant evolutionary elaboration during human evolution. One area of particular interest is Broca’s area, located in the left inferior frontal gyrus, which plays important roles in language processing. Unraveling the evolutionary history of this area is a key to the puzzle of the origin of language. Although generally known as a “language area,” cross-species neuroanatomical comparisons have identified apparently homologous areas in both apes and monkeys (our closest primate relatives). This means that Broca’s area did not evolve specifically for language, but instead was co-opted for language processing at some point during our evolutionary history. Presumably, this occurred because it processed information in a way that would have been useful to language. One intriguing possibility is that the original, pre-linguistic function of Broca’s area was to extract sequential patterns of any kind from the environment. Fossil and comparative primate evidence relevant to the evolution of Broca’s area will be reviewed, which suggest it has a long history of importance for communication. A model of language evolution will then be outlined that derives from a consideration of what we currently know about human brain evolution

How Senses Shape Language
Why do some linguistic phrases catch on and become more popular than others? There are multiple ways to convey the same thing and linguistic variants with similar meanings often act as substitutes, competing for usage. We study how the senses shape language evolution, suggesting that compared to their semantic equivalents (e.g., unfriendly person), linguistic variants which relate to senses in metaphoric ways (e.g., cold person) should be more culturally successful.

The Cultural Practice of Cognition
Everybody knows that humans are cultural animals. Although this fact is universally acknowledged, many opportunities to exploit it in cognitive science are overlooked. In this talk I draw on examples from a number of real-world activities to illustrate the ways in which human cognitive processes are orchestrated by cultural practices. I then explore some of the implications of this cultural basis of human cognition for both theory and method in cognitive science.

Language Adaptations, Non-Darwinian Processes, & Semiotic Constraints
I survey divergent features of human brains in the context of two evolutionary influences: 1. Demands imposed by adaptation to an artificial symbolic-linguistic niche (a variation on niche construction) 2. The synergistic effects of relaxation of selection due to tool use and self-domestication.

In addition, I consider how the self-organizing effects of social-transmission serve to regularize language structures, and highlight the critical influence of seldom-appreciated semiotic constraints on language structure and its quasi-universal features.

I conclude that it’s time to stop focusing too narrowly on natural selection processes, abandon an oversimplified computational conception of language structure, and pay attention to influences that can be ascribed neither to nature nor to nurture (i.e., semiotic constraints).

Face to Face, Brain to Brain: Exploring the Mechanisms of Dyadic Social Interactions
Cognition materializes in an interpersonal space. The emergence of complex behaviors requires the coordination of actions among individuals according to a shared set of rules. Despite the central role of other individuals in shaping our minds, experiments typically isolate human or animal subjects from their natural environment by placing them in a sealed quiet room where interactions occur solely with a computer screen. In everyday life, however, we spend most of our time interacting with other individuals.

In this talk I argue in favor of a shift from a single-brain to a multi-brain frame of reference. I present a series of studies aimed at characterizing the brain-to-brain coupling during real life social interaction. The data suggest that in many cases the neural processes in one brain are coupled to the neural processes in another brain via the transmission of a signal through the environment. The brain-to-brain neural coupling exposes a shared neural substrate that exhibits temporally aligned response patterns across communicators. The recording of the neural responses from two brains opens a new window into the neural basis of interpersonal communication, and may be used to assess verbal and non-verbal forms of interaction in both human and other model systems.
