Reducing Multi-Sensor Data To A Single Time Course That Reveals Experimental Effects, Aaron Schurger, Sebastien Marti, Stanislas Dehaene

Psychology Faculty Articles and Research

Background: Multi-sensor technologies such as EEG, MEG, and ECoG result in high-dimensional data sets. Given the high temporal resolution of such techniques, scientific questions very often focus on the time-course of an experimental effect. In many studies, researchers focus on a single sensor or the average over a subset of sensors covering a “region of interest” (ROI). However, single-sensor or ROI analyses ignore the fact that the spatial focus of activity is constantly changing, and fail to make full use of the information distributed over the sensor array.

Methods: We describe a technique that exploits the optimality and …

Single-Trial Decoding Of Auditory Novelty Responses Facilitates The Detection Of Residual Consciousness, J. R. King, F. Faugeras, A. Gramfort, Aaron Schurger, I. El Karoui, J. D. Sitt, B. Rohaut, C. Wacongne, E. Labyt, T. Bekinschtein, L. Cohen, L. Naccache, S. Dehaene

Psychology Faculty Articles and Research

Detecting residual consciousness in unresponsive patients is a major clinical concern and a challenge for theoretical neuroscience. To tackle this issue, we recently designed a paradigm that dissociates two electro-encephalographic (EEG) responses to auditory novelty. Whereas a local change in pitch automatically elicits a mismatch negativity (MMN), a change in global sound sequence leads to a late P300b response. The latter component is thought to be present only when subjects consciously perceive the global novelty. Unfortunately, it can be difficult to detect because individual variability is high, especially in clinical recordings. Here, we show that multivariate pattern classifiers can extract …

Exploring Epigenetic Regulation Of Fear Memory And Biomarkers Associated With Post-Traumatic Stress Disorder, Stephanie A. Maddox, Glenn E. Schafe, Kerry J. Ressler

Publications and Research

This review examines recent work on epigenetic mechanisms underlying animal models of fear learning as well as its translational implications in disorders of fear regulation, such as Post-traumatic Stress Disorder (PTSD). Specifically, we will examine work outlining roles of differential histone acetylation and DNA-methylation associated with consolidation, reconsolidation, and extinction in Pavlovian fear paradigms. We then focus on the numerous studies examining the epigenetic modifications of the Brain-derived neurotrophin factor (BDNF) pathway and the extension of these findings from animal models to recent work in human clinical populations. We will also review recently published data on FKBP5 regulation of …

Human Milk Cortisol Is Associated With Infant Temperament, Katherine R. Grey, Elyssia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

The implications of the biologically active elements in milk for the mammalian infant are largely unknown. Animal models demonstrate that transmission of glucocorticoids through milk influences behavior and modifies brain development in offspring. The aim of this study was to determine the relation between human milk cortisol levels and temperament of the breastfed infant. Fifty-two mother and infant pairs participated when the infants were three-months old. Milk cortisol levels were assessed and each mother completed the Infant Behavior Questionnaire (IBQ), a widely used parent-report measure of infant temperament. Analyses revealed a positive association between milk cortisol and the negative affectivity …

Treatment Of Psychiatric Inpatients With Relationship Dysfunction Using A Short Term Cognitive Interpersonal Intervention: A Pilot Study, Tamra Rasberry

Doctoral Dissertations and Projects

Relationship conflict for the psychiatric patient can have significant detrimental effects. There are specific types of interactions that can increase conflict and predict the potential for relapse; these have been identified by research and designated as components of Expressed Emotion (EE). Cognitive Behavioral Therapy (CBT) and Interpersonal Therapy (IPT) have been very effective when targeting specific psychiatric diagnoses, but less effective when addressing relationship conflict. The majority of studies addressing relationship conflict have taken place in an outpatient, long-term setting. There is limited research that utilizes an inpatient short-term intensive therapy with relationship conflict as its sole focus, targeting areas …

Research Brief: "Partnering With Communities To Address The Mental Health Needs Of Rural Veterans", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This research focuses on veterans in rural communities who have less access to mental health providers. The Yellow Ribbon Task Force program promoted and encouraged engagement in mental health care for veterans in rural communities, although future policies should enhance already existing clinical practices to increase standards for care. For further study, researchers should focus on evaluating initial program implementation and pilot testing in a variety of states and rural populations.

Diagnostic Interaction: First-Person Patient Narratives On Hacking's Looping Effects And The Normative Status Of Psychiatric Nosology, Corinne Jager

Honors College Theses

What is the interaction between a psychiatric patient and their diagnosis? How do they respond to being classified? A number of philosophical theories attempt to explain the interaction between the diagnosed patient and their classification. Ian Hacking develops an account of interaction which holds that objects of human science classification are influenced by the awareness of the classification in a way that changes both the classification and its object. Hacking thinks that psychiatric patients are “interactive kinds” whose awareness of their classification causes changes in the individuals' experience of themselves, and thus changes in their classification. Hacking claims that these …

Gait Analysis Of Teenagers And Young Adults Diagnosed With Autism & Severe Verbal Communication Disorders, Michael J. Weiss, Matthew F. Moran, Mary E. Parker, John T. Foley

All PTHMS Faculty Publications

Both movement differences and disorders are common within autism spectrum disorders (ASD). These differences have wide and heterogeneous variability among different ages and sub-groups all diagnosed with ASD. Gait was studied in a more homogeneously identified group of nine teenagers and young adults who scored as “severe” in both measures of verbal communication and overall rating of Autism on the Childhood Autism Rating Scales (CARS). The ASD individuals were compared to a group of typically developing university undergraduates of similar ages. All participants walked a distance of 6-meters across a GAITRite (GR) electronic walkway for six trials. The ASD and …

Two-Legged Hopping In Autism Spectrum Disorders, Matthew F. Moran, John T. Foley, Mary E. Parker, Michael J. Weiss

All PTHMS Faculty Publications

Sensory processing deficits are common within autism spectrum disorders (ASD). Deficits have a heterogeneous dispersion across the spectrum and multimodal processing tasks are thought to magnify integration difficulties. Two-legged hopping in place in sync with an auditory cue (2.3, 3.0 Hz) was studied in a group of six individuals with expressive language impaired ASD (ELI-ASD) and an age-matched control group. Vertical ground reaction force data were collected and discrete Fourier transforms were utilized to determine dominant hopping cadence. Effective leg stiffness was computed through a mass-spring model representation. The ELI-ASD group were unsuccessful in matching their hopping cadence (2.21 ± …

Dyscalculia: Characteristics, Causes, And Treatments, Gavin R. Price, Daniel Ansari

Numeracy

Developmental Dyscalculia (DD) is a learning disorder affecting the ability to acquire school-level arithmetic skills, affecting approximately 3-6% of individuals. Progress in understanding the root causes of DD and how best to treat it have been impeded by lack of widespread research and variation in characterizations of the disorder across studies. However, recent years have witnessed significant growth in the field, and a growing body of behavioral and neuroimaging evidence now points to an underlying deficit in the representation and processing of numerical magnitude information as a potential core deficit in DD. An additional product of the recent progress in …

Dead Men, Walking: Actors, Networks, And Actualized Metaphors In Mrs. Dalloway And Raymond, Elizabeth Outka

English Faculty Publications

This article takes up Rita Felski’s recent call to modernists to explore how Bruno Latour’s latest work on actor-network theory might be adapted for literary studies. It examines two accounts of World War I soldiers who (allegedly) return from the dead in material form: Virginia Woolf’s fictional account of Septimus Smith, who is convinced his friend Evans has come back from the dead, and Oliver Lodge’s best-selling memoir, Raymond, or Life and Death, which recounts in detail how Lodge believed his dead son sent messages to the family to assure them of his continued material existence. That these moments …

Relation Between Optimism And Lipids In Midlife, Julia K. Boehm, David R. Williams, Eric B. Rimm, Carol Ryff, Laura D. Kubzansky

Psychology Faculty Articles and Research

This research examined optimism’s relationship with total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, and triglycerides. The hypothesis that optimism is associated with a healthier lipid profile was tested. Participants were 990 mostly white men and women from the Midlife in the United States study who were on average 55.1 years old. Optimism was assessed by self-report with the Life Orientation Test. A fasting blood sample was used to assess serum lipid levels. Linear and logistic regression models examined the cross-sectional association between optimism and lipids accounting for covariates such as demographic characteristics (e.g., education) and …

Expression Of Borderline Personality Disorder Symptoms Across The Ovulatory Cycle: A Multilevel Investigation, Tory A. Eisenlohr-Moul

Theses and Dissertations--Psychology

Borderline Personality Disorder (BPD) is a disabling condition characterized by chronic emotion dysregulation and behavioral impulsivity. Prospective studies that test proposed mechanisms of within-person change in BPD hold the key to improving symptom predictability and control in this disorder. A small body of evidence suggests that fluctuations in estradiol such as those occurring naturally at ovulation during the monthly female reproductive cycle may increase symptoms in women with BPD (DeSoto et al., 2003). Furthermore, there is preliminary evidence that both self-esteem and feelings of social rejection are highest at ovulation, when estradiol peaks (Durante and Hill, 2009; Eisenlohr-Moul et al., …

Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres

LSU New Orleans Theses and Dissertations

Stress has been widely shown to directly influence people’s emotional and behavioral processing as well as their underlying biological systems. This project examined physiological and behavioral responses as indicators of stress and coping in the context of a psychosocial stressor in a controlled laboratory setting. We examined the association between indicators of behavioral coping and underlying physiological reactivity within participants while experiencing stress. Participants included 68 emerging adults. Physiological measures include autonomic biomarkers (e.g., heart-rate, skin conductance) at rest and during the stressor while behavioral indicators that were coded include acute verbal and non-verbal actions exhibited by participants during the …

Parametric Studies Of Antipsychotic-Induced Sensitization In The Conditioned Avoidance Response Model: Roles Of Number Of Drug Exposure, Drug Dose, And Test–Retest Interval, Natashia Swalve, Ming Li

Department of Psychology: Faculty Publications

Repeated haloperidol and olanzapine treatment produces an enhanced disruption of avoidance responding, a validated measure of antipsychotic activity. Experimental parameters affecting this sensitization-like effect have not been thoroughly examined. The present study investigated the role of three parameters (number of injections, dose, and interval between initial exposure and challenge) in antipsychotic sensitization in the conditioned avoidance response paradigm. Well-trained Sprague–Dawley rats received different numbers of drug treatment (1–5 days) or different doses of haloperidol (0.025–0.10 mg/kg, subcutaneously) or olanzapine (0.5–2.0 mg/kg, subcutaneously). After certain time intervals (4, 10 or 17 days), they were tested for the expression of haloperidol or …
