| Human visual attention, working memory, and learning | Human visual attention, working memory, and learning | We study visual selective attention using tasks such as visual search. We are interested in how visual attention is interdependent on visual working memory (short-term visual memory stores), as well as how long-term learning shapes visual attention. For instance, how do the contents of visual working memory affect attention (Beck & Vickery, 2019, 2020)? We employ behavioral experiments and fMRI neuroimaging to study these phenomena. | Vickery, Timothy | tvickery | | <img alt="" src="/content-sub-site/PublishingImages/human-visual-attention.jpg" style="BORDER:0px solid;" /> | | | | | |
| Human Visual Perceptual Organization | Human Visual Perceptual Organization | We study an important set of phenomena that fall under the umbrella of “perceptual organization,” such as perceptual grouping effects first studied by the Gestalt psychologists. These phenomena reflect mid-level human vision processes that set the stage for visual understanding, recognition, and visuomotor integration. Recently, we have begun investigating individual differences in these phenomena, searching for clues as to which ones share underlying mechanisms. We study this with human psychophysical experiments that measure the effects of different kinds of grouping and segmentation. | Vickery, Timothy | tvickery | | <img alt="" src="/content-sub-site/PublishingImages/Human-Visual-Perceptual-Organization.jpg" style="BORDER:0px solid;" /> | | | | | |
| Object‐based warping | Object‐based warping | Objects seem to distort the perception of spatial relationships (Vickery & Chun, 2010). Current psychophysical and neuroimaging research in the Vickery lab seeks to map and better understand how and when this distortion occurs, when it leads to expansion vs. compression of perception, how this illusion relates to brain activity (measured with fMRI), and why it might arise from the way that objects are represented in visual cortex. | Vickery, Timothy | tvickery | | <img alt="" src="/content-sub-site/PublishingImages/object‐based-warping.jpg" style="BORDER:0px solid;" /> | | | | | |
| Interracial Contact and Social Cognition | Interracial Contact and Social Cognition | The rapid increase in the racial diversity of our population provides us with growing opportunities to interact with other-race individuals. Whereas investigations of how interracial contact shapes intergroup attitudes and person evaluation have a long scholarly tradition, little is known about how interracial contact influences social cognition beyond intergroup relations. In this line of research, we utilize social cognitive tasks and neuroimaging (fMRI/EEG) to examine how individual differences in intergroup contact across the lifespan influence various social cognitive abilities. We are currently testing potential behavioral and neural consequences of contact diversity in the context of mentalizing ability. | Cloutier, Jasmin;Kubota, Jennifer | jcloutier;jtkubota | | <img alt="" src="/Images%20Bios/Interracial%20Contact%20and%20Social%20Congnition.jpg" style="BORDER:0px solid;" /> | | | | | |
| Social Environments and Stereotyping | Social Environments and Stereotyping | Another research question surrounds whether and how implicit and explicit associations interact with visual components of the environment. This area of inquiry also explores how variation in the target individual's features, and in the perceiver's stereotype endorsement, facilitate or hinder social categorization and stereotyping. | Cloutier, Jasmin;Kubota, Jennifer | jcloutier;jtkubota | | <img alt="" src="/Images%20Bios/Social%20Environments%20and%20Sterotyping.jpg" width="640" style="BORDER:0px solid;" /> | | | | | |
| Neural correlates of percept- and knowledge-based impressions | Neural correlates of percept- and knowledge-based impressions | Using fMRI and EEG, we examine how the availability and use of person-knowledge impacts neural activity when perceiving and evaluating others based on physical cues (i.e., a judgment that requires no person-knowledge) or person-knowledge (e.g., an individual’s past behavior). The goal of these projects is to uncover the processes supporting the use of each kind of information and to identify how individuals weight the various kinds of information when forming impressions and making decisions. | Cloutier, Jasmin;Kubota, Jennifer | jcloutier;jtkubota | | <img alt="" src="/Images%20Bios/Neural%20correlates%20of%20percept%20-%20and%20knowledge%20-%20based%20impressions.jpg" style="BORDER:0px solid;" /> | | | | | |
| Police officer-civilian interactions | Police officer-civilian interactions | We are currently conducting a series of projects examining the perception of police officer-civilian interactions. The growing number of publicly available video recordings of police officer-civilian interactions has elicited divergent public opinions ranging from complete justification of the officer to calls for criminal charges against the officer. Accordingly, this work is timely and aims to identify how the individual differences of perceivers impact evaluations of both the police officer and civilian. This project explores fundamental social cognitive processes (i.e., implicit and explicit associations) and real-world outcomes (e.g., perceptions of aggression and legitimacy) using fMRI, stress reactivity, and eye-tracking. | Cloutier, Jasmin;Kubota, Jennifer | jcloutier;jtkubota | | <img alt="" src="/Images%20Bios/Police%20officer%20-civilian%20interations.jpg" style="BORDER:0px solid;" /> | | | | | |
| Social Neuroscience Framework for the Study of Status | Social Neuroscience Framework for the Study of Status | Our lab systematically investigates the perception of status (i.e., hierarchical rank) and its consequences for how we attend to and evaluate others. In our recently published social neuroscience framework for the study of status, we distinguish between (1) status dimensions (i.e., domains in which an individual may be ranked, such as wealth), and (2) status level (i.e., one’s rank along a given dimension). One key takeaway from this distinction is that one's status level may depend on the status dimension in question (e.g., low in financial status, high in moral status). These differences may have important consequences for how we evaluate and interact with those occupying different positions in a given social hierarchy. Additionally, we are interested in how different contexts and status cues may shape status-based evaluations and decisions. Inspired by our social neuroscience framework for the study of status-based evaluations, we are currently exploring how status may interact with salient visible social categories such as race, age, and gender. This work uses a combination of classic social cognitive tasks and neuroimaging (fMRI/EEG). | Cloutier, Jasmin;Kubota, Jennifer | jcloutier;jtkubota | | <img alt="" src="/Images%20Bios/Social%20Neuroscience%20Framework%20for%20the%20Study%20of%20Status%202.jpg" style="BORDER:0px solid;" /> | | | | | |
| Examining the Etiology of Chronic Emotional & Behavioral Dysregulation in Adulthood. | Examining the Etiology of Chronic Emotional & Behavioral Dysregulation in Adulthood. | Sustained difficulties with emotion regulation, distress tolerance, and behavioral control are common across different forms of psychopathology, including externalizing traits, antisocial and borderline personality disorders, psychopathy, & PTSD. In addition to causing significant distress and functional impairment, these disorders have proven difficult to treat, partly due to a lack of understanding of the cognitive, affective, and environmental variables that maintain symptoms overtime. Research in the lab aims to gain a better understanding of the etiological mechanisms (cognition-emotion interactions, personality traits, biological vulnerabilities) that contribute to these disorders and their associated features (e.g., emotional lability, impulsivity, stress reactivity). The goal of this research is to gain a deeper understanding of the causes and developmental pathways to disorders characterized by chronic emotional and behavioral dysregulation. | Samimi-Sadeh, Naomi | nsadeh | | <img alt="" src="/Images%20Bios/9-1cftjo9.png" style="BORDER:0px solid;" /> | | | | | |
| Identifying Biomarkers of Disinhibition. | Identifying Biomarkers of Disinhibition. | Impulse control deficits and poor self-regulation are core features of a diverse array of harmful behaviors (aggression, substance use, risky sexual behavior) and mental disorders (antisocial personality disorder, PTSD, externalizing disorders) that increase risk for premature death and poor health outcomes. We are working on identifying neurobiological mechanisms that support adaptive inhibitory control in healthy populations and how these regulatory processes go awry in clinical samples. The goal of this work is to better understand the neural architecture of impulse control deficits across different forms of psychopathology and to clarify how the neural processes supporting inhibition interact with other cognitive, motivational, and emotional systems. | Samimi-Sadeh, Naomi;Spielberg, Jeffrey | nsadeh;jmsp | | <img alt="" src="/Images%20Bios/Picture1-1vpvuil.png" style="BORDER:0px solid;" /> | | | | | |
| Dyslexia | Dyslexia | We are testing the magnocellular hypothesis of dyslexia, which suggests that the root cause of dyslexia may be caused by malfunctions of the magnocellular system in the brain. We are measuring the structure and function of the lateral geniculate nucleus in people with dyslexia and controls. | Schneider, Keith | keithas | | <img alt="" src="/Images%20Bios/dyslexia%20a.png" style="BORDER:0px solid;" /> | | | | | |
| Attention and appearance | Attention and appearance | As part of a longstanding debate in the literature, we are studying whether paying attention to an object actually changes its subjective appearance, or whether it just changes our response criterial and decision biases. | Schneider, Keith | keithas | | <img alt="" src="/content-sub-site/PublishingImages/attention%20and%20appearance%20A.png" style="BORDER:0px solid;" /> | | | | | |

| Methods for understanding the organization of brain networks | Methods for understanding the organization of brain networks | The study of brain networks is central to understanding how the brain supports complex thought and behavior and how related dysfunction gives rise to psychopathology. Typical methods catalogue the presence or absence of connections, ignoring the larger (network) context in which such connections occur. In collaboration with colleagues in Mathematical Sciences, the CAD lab develops and refines graph theory metrics to capture the manner in which network organization (of connections) impacts network function (e.g., robustness to external interference). A particular focus is on spectral methods that may more effectively represent network organization. These developments are integrated into our publicly available toolbox (http://www.nitrc.org/projects/metalab_gtg/). | Spielberg, Jeffrey | jmsp | Sebastian Cioabă, Mathematical Sciences | <img alt="" src="/content-sub-site/PublishingImages/proj_4.png" style="BORDER:0px solid;" /> | | | | | |
| Brain networks supporting mania and depression in bipolar disorder | Brain networks supporting mania and depression in bipolar disorder | In collaboration with colleagues at Cleveland Clinic, the CAD lab is conducting several studies aimed at parsing brain network disturbances observed in bipolar disorder into those unique to mania, unique to depression, and common to both. In addition, we are examining the impact of lithium treatment (e.g., whether disturbed networks are normalized, whether compensatory networks come online). Finally, we are investigating whether depression is associated with different network disturbances in the context of unipolar depression rather than bipolar disorder. Note, data collection for this project currently occurs at Cleveland Clinic. | Spielberg, Jeffrey | jmsp | | <img alt="" src="/content-sub-site/PublishingImages/proj_3.png" style="BORDER:0px solid;" /> | | | | | |
| Interaction of brain networks supporting motivation and inhibition | Interaction of brain networks supporting motivation and inhibition | Adaptive functioning depends on the rapid regulation of motivational processes, and disturbances in this regulation are key features of anxiety and depression. The CAD lab is conducting a number of studies aimed at understanding how brain networks supporting top-down inhibitory control interact with those involved in identifying the motivational importance of stimuli. This work is conducted in both healthy and anxious/depressed individuals, allowing us to describe both the typical manner in which these circuits interact and how divergence from the norm may lead to pathology. | Spielberg, Jeffrey;Samimi-Sadeh, Naomi | jmsp;nsadeh | | <img alt="" src="/content-sub-site/PublishingImages/proj_2.png" style="BORDER:0px solid;" /> | | | | | |
| Adolescent development in brain networks supporting motivation | Adolescent development in brain networks supporting motivation | Adolescence is the peak onset time for psychopathology involving disturbances in motivation and emotion, including anxiety and depression. Thus, charting the neuromaturational trajectories of brain networks supporting motivation and emotion may prove crucial to discovering how and why psychopathology develops during this period, and ultimately informing prevention and treatment efforts. The CAD lab is conducting several studies aimed at key pieces of this puzzle, including the development and consolidation of connections between amygdala and orbitofrontal cortex (OFC), with a particular focus on the role of pubertal hormones. | Spielberg, Jeffrey | jmsp | | <img alt="" src="/content-sub-site/PublishingImages/proj_1.png" style="BORDER:0px solid;" /> | | | | | |
| Perceptual contributions to racial biases in pain recognition | Perceptual contributions to racial biases in pain recognition | There are pervasive racial and ethnic disparities in medical treatment in the United States. For instance, the pain of Black patients is systematically under-diagnosed and under-treated, compared to the pain of Whites. While other research has examined higher-level factors fueling such biases (e.g., perceptions of status, stereotypes about biological differences between Blacks and Whites), we're interested in examining whether racial biases in pain recognition might also stem from a perceptual basis. We've observed that pain on Black faces is less readily perceived than pain on White faces, stemming from a disruption in configural processing associated with other-race faces. Further, these biases in perception predict biases in treatment behavior. Currently, we're exploring the neural bases of these biases, examining whether these biases are observable in medical health professionals, and beginning to develop interventions designed to attenuate these perceptual contributions to racial biases in pain recognition. | Mende-Siedlecki, Peter | pmende | | <img alt="" src="/content-sub-site/PublishingImages/RacialBiasPain_Pic3.png" style="BORDER:0px solid;" /> | | | | | |
| Neural dynamics supporting impression updating | Neural dynamics supporting impression updating | How does the brain support our ability to change our minds about other people? Using fMRI, we've observed that impression updating is supported neurally by a distributed network of brain regions and that activity in a subset of these regions (in particular, vlPFC & IFG) is preferential for diagnostic changes in behavior, beyond mere moment-to-moment inconsistencies. Critically, we've observed that perceptions of behavioral frequency are a critical factor in the updating process: behaviors that are perceived to be more rare (e.g., highly immoral or highly competent behaviors) drive updating on both behavioral and neural levels. We're currently using computational modeling approaches to better characterize the neural dynamics supporting updating -- for example, to examine how this sort of complex social learning is contextualized and generalized. | Mende-Siedlecki, Peter | pmende | | <img alt="" src="/content-sub-site/PublishingImages/NeuralDynamics_Pic1.png" style="BORDER:0px solid;" /> | | | | | |
| Impact of Zika Virus Infection on the Developing Brain | Impact of Zika Virus Infection on the Developing Brain | Zika virus (ZIKV) infection in pregnant women has been linked to a neurological disorder in the fetus called microcephaly; and we hypothesize this is due to robust inflammatory response to ZIKV in the fetal brain that precipitates neurological damage. The ongoing experiments in our lab will examine the impact of maternal ZIKV infection on inflammation, microglial activation, and associated neural cell death in the fetal brain using a rat model of ZIKV infection. The immediate goal of these experiments is to determine whether ZIKV activates microglia within the developing fetal brain, and to identify key inflammatory and cellular targets for potential therapeutic interventions for ZIKV associated neurological disorder. Using the data obtained in these experiments, future experiments can also examine the impact of prenatal ZIKV infection on long-term neural, immune, and behavioral outcomes in infected offspring that do not have severe neural deformations. | Schwarz, Jaclyn | jschwarz | | <img alt="" src="/content-sub-site/PublishingImages/E17%20cell%20morphology%20picture%2040X.jpg" style="BORDER:0px solid;" /> | | | | | |
| Visual Statistical Learning | Visual Statistical Learning | Humans rapidly learn statistical associations among visual stimuli, even when they are not aware of such contingencies and are not trying to learn those associations. This is called visual statistical learning, and it may play an important role in such tasks as navigation and categorization, or even in basic perceptual organization. In the Perception and Learning lab, we use behavior and fMRI neuroimaging to study numerous aspects of this phenomenon: when, how, and why it occurs, and what are the consequences? | Vickery, Timothy | tvickery | | <img alt="" src="/content-sub-site/PublishingImages/Vickery%20lab%20picture.jpg" style="BORDER:0px solid;" /> | | | | | |
| Children’s Spatial Cognition | Children’s Spatial Cognition | STEM learning draws heavily on spatial cognitive abilities. At the University of Delaware Early Learning Center, we conduct scene perception and spatial memory research with 4-5 year old preschool children, exploring rapid scene perception and testing to determine the developmental trajectory of anticipatory spatial projections, such as boundary extension. Through collaboration with other labs we have tested infant scene memory and are studying spatial memory in children with developmental disorders. | Intraub, Helene | intraub | | <img alt="" src="/Images%20Bios/Kids%20drawings.jpg" style="BORDER:0px solid;" /> | | | | | |
| Spatial Representation: Vision & Haptics | Spatial Representation: Vision & Haptics | Most scene perception research makes use of photographs as stimuli. Here we seek to understand the mental representation of regions of real space given the ability to navigate and to gain input for different modalities (vision and haptics) – independently and in combination. We have studied memory in blindfolded-sighted individuals and a woman who was deaf and blind since early life. We also study the interaction of top-down expectations and low vision (simulated loss of periphery) on memory for surrounding space. | Intraub, Helene | intraub | | <img alt="" src="/Images%20Bios/renee_vis_touch.jpg" style="BORDER:0px solid;" /> | | | | | |
| Visual Scene Perception and Memory | Visual Scene Perception and Memory | Using brief presentation and eye tracking experiments we study what can grasped in a fraction of a second from a scene. We have also observed rapid effects of top-down expectations on what is remembered – observing false memory for unseen information just beyond the boundaries of a view as soon as 1/20th after viewing a photograph – a phenomenon called boundary extension, discovered in our lab. In behavioral studies we explore the multiple factors that affect both veridical and anticipatory memory that predicts upcoming layout. Through collaboration with other labs we explore the brain mechanisms underlying boundary extension. | Intraub, Helene | intraub | | <img alt="" src="/Images%20Bios/Brief%20Presentation%20BE%20copy.jpg" style="BORDER:0px solid;" /> | | | | | |
| Diversity Competence Model | Diversity Competence Model | James Jones has developed the idea of diversity competency—the perspective, attitude and motivation to interact in and benefit from diverse contexts and relationships. The diversity competence model consists of five main features: diversity self-awareness, perspective taking, cultural intelligence, personal and social responsibility and knowledge application. We have developed a 15-item diversity competency scale, which has demonstrated good psychometric properties and is associated with a variety of trait level characteristics integral to prosocial behaviors. Current research explores the ways in which diversity competency is expressed in problem solving, interpersonal relationships and interactions, decision-making and academic success. The research further explores how academic curriculum and co-curricular activities contribute to the development of diversity competency. | Jones, James M. | jmjones | | <img alt="" src="/content-sub-site/PublishingImages/0323-psych-office3.JPG" style="BORDER:0px solid;" /> | | | | | |

| The Role of MS/DBB Cholinergic input to the Hippocampus in Extinction Memory and Contextual Fear Memory Generalization | The Role of MS/DBB Cholinergic input to the Hippocampus in Extinction Memory and Contextual Fear Memory Generalization | Current definitions of the extinction circuit in the mammalian brain focus on medial prefrontal cortical inhibition of amygdala activity and subcortical substrates. We have previously shown that cholinergic neurons in the medial septum and diagonal bands of Broca (MS/DBB) are critical for acquisition of extinction. However, neural circuitry through which these neurons modulate extinction memory processes are unknown. In this study, we test the hypothesis that MS/DBB cholinergic input to the dorsal hippocampus is critical for acquisition of extinction memory. Undergraduate Researchers: Jennifer Staib

| Nature of Extinction Retention Deficits in the Single Prolonged Stress Paradigm | Nature of Extinction Retention Deficits in the Single Prolonged Stress Paradigm | We have previously shown that exposing rats to single prolonged stress results in extinction retention deficits. However, it is not clear if this is due to enhanced fear memory or deficits in extinction memory. Our previous attempts to address this question using behavioral methods were inconclusive. In this study we used changes in expression of transcription factors as measures of neural activity to map neural activity throughout the fear circuit during fear memory formation and extinction memory formation. By doing this we will attempt to determine if single prolonged stress exposure leads to extinction retention deficits by altering neural activity during fear memory formation or extinction memory formation.

| The Role of Glucocorticoid Binding During Fear Conditioning in SPS-Induced Extinction Retention Deficits | The Role of Glucocorticoid Binding During Fear Conditioning in SPS-Induced Extinction Retention Deficits | We have previously shown that exposing rats to single prolonged stress results in extinction retention deficits and that inhibiting glucocorticoid release during fear conditioning exacerbates these deficits. These previous findings suggest that single prolonged stress-induced changes in glucocorticoid receptors can be adaptive. We will test this hypothesis by showing that activation of glucocorticoid receptors in the ventral hippocampus of single prolonged stressed rats during fear conditioning leads to attenuated extinction retention deficits in rats exposed to single prolonged stress.

| Language Acquisition: a Cross-Linguistic Perspective | Language Acquisition: a Cross-Linguistic Perspective | How can very young children acquire the words and structures of their native language? We mostly study children between the ages three to five from a variety of language backgrounds (e.g., English, Greek, Turkish and Korean).
