    Title: The development of causal thought

    Abstract: We rely on the human mind’s uniquely sophisticated understanding of cause and effect when we flick a light switch to turn on a light, or recognize that an object’s movement is caused by the person holding it rather than the other way around, or even understand the meaning of a verb. Yet there are foundational questions about causality in the mind that we have not yet answered. How do infants’ understandings of simple causal events become the complex causal concepts that we manipulate as adults, and the even more intricate causal reasoning we engage in as scientists? Past work has argued that mature causal understanding springs from a single atomic notion of causality but disagreed about whether that origin is a perceptual module, a domain-general learning system, or the experience of being a causal agent. I will present recent projects that support a different kind of explanation: that we start with multiple, disconnected ways of understanding cause and effect, and must construct a more integrated concept of causality later in development.

    Bio:I am interested in how our minds represent the many cause-and-effect relationships we encounter in our daily lives, and how these representations are used in reasoning, perception, and action. I use tools from vision science, cognitive psychology, and developmental psychology to examine what kinds of causality are represented in the mind, how different kinds of causal representations may be related to each other, and how they emerge during development.

    I also created PyHab, an open-source system for infant looking-time studies. It is designed for real time infant gaze coding and stimulus presentation, and creates self-contained experiment folders to make it easier to share your whole experiment, stimuli and code, across labs or for repositories like OSF. You can find out more about it here .

    I am currently a postdoctoral associate in the Computational Cognitive Development Group at Rutgers - Newark. Before that, I was a postdoctoral fellow at the Harvard Lab for Developmental Studies for three years.

  • “The Problem with the Phrase “Women and Minorities”: Intersectionality, An Indispensable Critical Theoretical Framework for Behavioral and Social Health Science Research”

    Friday, September 25, 2020
     12:00 PM – 12:55 PM
    Zoom ID: 927 3899 8271

    Historically rooted in Black feminist activism, intersectionality is a critical theoretical framework that posits that power and social inequity are differently structured, and vary based on people’s multiple and intersecting demographic positions (e.g., race, ethnicity, gender, gender and sexual minority status, socioeconomic status). Intersectionality has made impressive inroads within the behavioral and social health sciences (BSHS) in recent years. It enhances BSHS research by challenging “single-axis” assumptions such as that connoted by the phrase “women and minorities,” and centering the experiences and needs of people marginalized by intersectional discrimination. This presentation will: (1) provide an overview of intersectionality, its history, and core tenets; (2) describe how intersectionality challenges conventional assumptions about groups of people and social issues; (3) highlight applications of intersectionality to NIH-funded health research with U.S. Black men; and (4) discuss why critical perspectives such as intersectionality are indispensable for BSGS researchers committed to social justice work.

     

    Lisa Bowleg, Ph.D. is Professor of Applied Social Psychology in the Department of Psychological and Brain Sciences at The George Washington University (GW), Director of the Social and Behavioral Sciences Core of the DC-Center for AIDS Research, and the Founding Director of the Intersectionality Training Institute at GW. She is a leading scholar of the application of intersectionality to social and behavioral science research, as well as research focused on HIV prevention and sexuality in Black communities.

    Michael S. Goodman ’74 Memorial Seminar Series.

    Speaker: Melisa Menceloglu (Postdoc at Song Lab)

    Title: Behavioral and EEG Investigations of Temporal Orienting of Attention in Vision & Audition
    Abstract:
    Orienting attention enables us to efficiently select, process, and react to relevant objects in complex environments. Just as we can orient attention in space and to certain object features, recent research has shown that we can also orient attention in time (temporal orienting). In my graduate work, I studied the mechanisms and the effects of temporal orienting driven by various temporal structures (e.g. single intervals, rhythms, passage of time) and under different task/attentional demands using behavioral and EEG methods. In this talk, I will present my work on interval-based temporal orienting (this can be thought of as the temporal analog of spatial cueing where certain cue-to-target intervals, instead of target locations, are cued/more probable). I will present a series of behavioral studies where I demonstrate that (1) not just explicitly but also implicitly learned temporal structures can lead to temporal orienting and influence response times without influencing response conflict in the visual modality, (2) temporal orienting weights visual signals more strongly than auditory signals in the context of audiovisual competition, and (3) temporal orienting is controlled independently from attentional orienting to specific sensory modalities across the auditory and visual modalities. Lastly, I will present an EEG study where I use auditory and visual steady-state evoked potentials to examine the effects of temporal orienting on the ongoing sensory processing across perceptual and motor tasks.

    Bio: Melisa Menceloglu is a Postdoctoral Research Associate in the CLPS department at Brown. Her research focuses on perception, action, and attentional processes in the temporal domain. She uses behavioral and EEG methods to understand how we generate expectations about timing of events and orient attention to specific points in time, and how auditory and visual perceptual processes and goal-directed action are altered with temporal orienting of attention.

    Title: Social Network Interventions
    Abstract: Human beings choose their friends, and often their neighbors, and co-workers, and we inherit our relatives; and each of the people to whom we are connected also does the same, such that, in the end, we humans assemble ourselves into face-to-face social networks. Why do we do this? And how might a deep understanding of human social network structure and function be used to intervene in the world to make it better? Here, I review recent research from our lab describing three classes of interventions involving both offline and online networks that can help make the world better: (1) interventions that rewire the connections between people; (2) interventions that manipulate social contagion, facilitating the flow of desirable properties within groups; and (3) interventions that manipulate the position of groups of people within network structures. I will illustrate what can be done using a variety of experiments in settings as diverse as fostering cooperation in networked groups online, to fostering health behavior change in developing world villages, to facilitating the diffusion of innovation or coordination in groups. I will also focus on recent experiments with “hybrid systems” comprised of both humans and “dumb bots,” involving simple artificial intelligence (AI) agents interacting in small groups. By taking account of people’s structural embeddedness in social networks, and by understanding social influence, it is possible to intervene in social systems to enhance desirable population-level properties as diverse as health, wealth, cooperation, coordination, and learning.

  • Please join us on Wednesday, September 23rd at 1PM EST for a presentation by Dr. Nicole Nugent: “Ecological Sampling of Affect, Social Context and Suicidal Thoughts and Behaviors.” For adolescents hospitalized for suicidal thoughts and behaviors, the transition from inpatient to the home environment is a high risk time for repeated attempts, re-hospitalization, and even death by suicide. However, most research aimed at understanding the factors that contribute to this risk is implemented retrospectively, resulting in a host of biases in reporting and preventing treatment developers from fully capitalizing on intervention efforts that could be implemented in the real world after adolescents leave inpatient.

    Dr. Nugent’s research (R01MH105379) used ecological sampling methods to assess adolescent affect, social experiences, and suicidal thoughts and behaviors in real time over the course of 3 weeks following discharge from inpatient hospitalization. Preliminary analyses support the importance of understanding dynamic affect in the moment, with ecological momentary assessment, the electronically activated recorder, and online social networking. Nuances of this work and clinical implications for translation to just in time adaptive interventions (JITAIs) will be briefly described.

    Nicole Nugent, PhD is an Associate Professor in the Departments of Psychiatry and Human Behavior, Pediatrics, and Emergency Medicine at the Warren Alpert Medical School of Brown University and is a child clinical psychologist at Hasbro Children’s Hospital. Dr. Nugent is Associate Director of the Center for Digital Health, where she collaborates with colleagues throughout the digital health community to develop impactful tools for scientific understanding and individual treatment. She is also Director of the Rhode Island Resilience Project and Associate Director of the Stress Trauma and Resilience (STAR) Institute, positions aimed at furthering the field of traumatic stress through research, training, and community outreach. Dr. Nugent serves as Director of Resilience and Psychological Services at the Hasbro Pediatric Refugee Clinic, a role that informs research efforts that permit translation to intervention across diverse populations.

    Speaker: Lelia Glass (Georgia Tech)

    Title: The lexical and compositional semantics of distributivity

    Abstract: Some predicates are distributive (true of each member of a plural subject: if two people smile, they each do). Others are nondistributive (if two people meet, they do so jointly rather than individually), or go both ways: if two people open a window, perhaps they each do so (distributive), or perhaps they do so jointly but not individually (nondistributive).

    This paper takes up the rarely-explored lexical semantics question of which predicates are understood in which way(s) and why, presenting quantitative evidence for predictions about how certain features of an event shape the inferences drawn from the predicate describing it. Causative predicates (open a window), and predicates built from transitive verbs more generally, are shown to favor a nondistributive interpretation, whereas experiencer-subject predicates (love a movie) and those built from intransitive verbs (smile) are mostly distributive.

    Turning to the longstanding compositional semantics question about how distributivity should be represented semantically, any such theory ends up leaving much of the work to lexical/world knowledge of the sort that this paper makes explicit.

    Bio: Assistant Professor of Linguistics in the School of Modern Languages at Georgia Tech .

    She works on lexical semantics (word meaning), compositional semantics (sentence meaning), and pragmatics (inferences drawn in context) from an empirically rich perspective. She is particularly interested in how our knowledge of the (physical, social) world affects our interpretation of language.

    Title: Mapping and shaping cognitive representations of immigrants
    Abstract: Who or what is mentally conjured when you hear “undocumented immigrants” or “illegal immigrants”? What if they’re further described as Mexican, Irish, welfare recipients, criminals, or high achievers? The contents of these representations fundamentally reflect how immigrants are understood within and between individuals, constituting a bridge between structural forces and political decision- and meaning-making. Across four studies, I take advantage of recent methodological advances to 1) map cognitive representations of immigrants across evaluative, visual, and geographic spaces, 2) quantify how shared they are, and 3) explore how we might modify them. Results reveal how immigrant representations are consistently and widely racialized through the incorporation of strongly institutionalized and thus readily available racial schemas. This cognitive racialization can be countered (to some extent) and does not occur uniformly across people as there exists meaningful and clustered variation in immigrant representations. Together these findings place social cognition in more direct conversation with critical theorizing and offer fresh approaches for investigating relations between individual and collective beliefs.

  • One of the many difficulties in 3D deep learning is a lack of large,
    clean and labeled datasets. Acquiring and labeling large amounts of 3D
    data is not only cumbersome, but also requires using fundamental
    geometry processing pipelines that are not robust to geometry in the
    wild. Moreover, even high-quality 3D mesh models for similar shapes are
    extremely inconsistent with respect to triangulation and
    water-tightness, for example. On the other hand, training neural
    networks on single images has demonstrated surprisingly superb
    performance on a variety of different tasks. In this talk, I will
    present two recent works which propose training deep networks on a
    single shape, as well as discuss a future work in this direction. In
    Point2Mesh [SIGGRAPH 2020], we leverage the inductive bias of
    convolutional neural networks to learn a self-prior for surface
    reconstruction. We iteratively deform an initial mesh to “shrink-wrap”
    the input point cloud, resulting in a watertight mesh reconstruction.
    The weight-sharing property of CNNs models recurring and correlated
    structures within a single shape, and inherently removes noise and
    outliers. In Deep Geometric Texture Synthesis [SIGGRAPH 2020], we train
    a hierarchical GAN to learn to model the local geometric textures of a
    single shape. Our network displaces mesh vertices in any direction
    (i.e., in the normal and tangential direction), enabling synthesis of
    geometric textures, which cannot be expressed by a simple 2D
    displacement map.

    Title: Visual and Auditory Polyrhythm Perception
    Abstract: Engaging in time perception through music has long been a celebrated and culturally relevant practice. What is peculiar, however, is that humans do not possess a specific sensory organ that is dedicated to perceiving time. Here we investigated whether timing precision varied across vision and audition, and whether the complexity of the meter impacted individuals’ sensitivity to tempo changes. We presented computer-generated stimuli and measured sensitivity to tempo changes. Visual stimuli comprised gratings that modulated at one tempo and plaids that combined tempos into a 3-against-2 polyrhythm. Auditory stimuli differed by three octaves and modulated in isolation or in a 3:2 ratio to create auditory polyrhythms. College students classified the tempo of each stimulus as faster or slower than an “average” tempo. Thresholds did not differ significantly across vision and audition, regardless of task. However, participants generated significantly lower (better) timing thresholds while making judgements on Slow Isolation Tempo trials than on Fast Isolation or Fast Polyrhythm Tempo conditions. The observed effect demonstrates that college students possess greater sensitivity to timing differences at slow tempos (~120 beats per minute or 3 Hz). In the context of our study, the implicit grouping of a polyrhythm did not aid nor distract the observer while making tempo judgements, and the sensory mode of the stimulus did not impact timing precision.

    Title: Beyond Fitts’s Law: A Three-Phase Model Predicts Movement Time to Position an Object in an Immersive 3D Virtual Environment
    Abstract:
    Objective: The study examines the factors determining the movement time (MT) of positioning an object in an immersive 3D virtual environment.Background: Positioning an object into a prescribed area is a fundamental operation in a 3D space. Although Fitts’s law models the pointing task very well, it does not apply to a positioning task in an immersive 3D virtual environment since it does not consider the effect of object size in the positioning task.
    Method: Participants were asked to position a ballshaped object into a spherical area in a virtual space using a handheld or head-tracking controller in the ray-casting technique. We varied object size (OS), movement amplitude (A), and target tolerance (TT). MT was recorded and analyzed in three phases: acceleration, deceleration, and correction.
    Results: In the acceleration phase, MT was inversely related to object size and positively proportional to movement amplitude. In the deceleration phase, MT was primarily determined by movement amplitude. In the correction phase, MT was affected by all three factors. We observed similar results whether participants used a handheld controller or head-tracking controller. We thus propose a three-phase model with different formulae at each phase. This model fit participants’ performance very well.
    Conclusion: A three-phase model can successfully predict MT in the positioning task in an immersive 3D virtual environment in the acceleration, deceleration, and correction phases, separately.
    Application: Our model provides a quantitative framework for researchers and designers to design and evaluate 3D interfaces for the positioning task in a virtual space.

    Title: Perceptual-motor Recalibration in Naturalistic and Virtual Environments
    Abstract: The way people learn to interact with the physical world can be conceptualized as a perception-action loop. For new situations, existing schemes are used to make predictions, take actions, and adjust actions based on the feedback. Through this system, people can adapt their motions, such as walking and turning, as environmental conditions change. This locomotive recalibration has been investigated in several experiments in the naturalistic environment. However, there has been less research examining recalibration effects in immersive virtual environments. The present research investigated 1) how perceptions and actions work together and 2) how people respond differently to virtual and naturalistic environments. Specifically, it examined whether a recalibration effect created in a virtual environment had the same characteristics as rotational locomotion in the naturalistic environment. It followed the designs of previous experiments in naturalistic environments and consisted of a pre-test, recalibration phase, and a post-test. The results indicated that there is the same recalibration effect in naturalistic and virtual environments, and rotational recalibration effects transfer between naturalistic and virtual contexts.

  • In this work, I present an implemented model that can learn interactively from natural language, enabling non-expert human trainers to convey complex tasks to machines using task decomposition and a combination of evaluative feedback and natural language.

    Over a series of experiments and associated algorithms, I show:
    (1) Contrary to the assumptions of methods that learn behavior interactively, feedback from people is policy dependent.
    (2) The method of COnvergent Actor-Critic by Humans (COACH) can interpret and learn from this kind of feedback.
    (3) Complex tasks can be hard to learn directly from feedback, but non-expert human trainers can decompose complex tasks into simpler units.
    (4) Geometric Linear Temporal Logic (GLTL) can be used as a logical form that can capture decomposed task descriptions and serve as the basis of an effective learning algorithm for building complex tasks.
    (5) People can use natural language feedback to convey evaluative feedback effectively.
    (6) A deep sequence-to-sequence (Seq2Seq) approach can be used to interpret natural language feedback while discovering how to convert spontaneous natural language input to GLTL for machine execution.

    These elements are demonstrated in an implemented system that learns online from interaction with an end user to interpret and execute the user’s tasks.
