The Impact Of Multisensory Integration Deficits On Speech Perception In Children With Autism Spectrum Disorders., Ryan A Stevenson, Magali Segers, Susanne Ferber, Morgan D Barense, Mark T Wallace

Brain and Mind Institute Researchers' Publications

Speech perception is an inherently multisensory process. When having a face-to-face conversation, a listener not only hears what a speaker is saying, but also sees the articulatory gestures that accompany those sounds. Speech signals in visual and auditory modalities provide complementary information to the listener (Kavanagh and Mattingly, 1974), and when both are perceived in unison, behavioral gains in in speech perception are observed (Sumby and Pollack, 1954). Notably, this benefit is accentuated when speech is perceived in a noisy environment (Sumby and Pollack, 1954). To achieve a behavioral gain from multisensory processing of speech, however, the auditory and visual …

Diffusion Tensor Imaging And White Matter Abnormalities In Patients With Disorders Of Consciousness., Carlo Cavaliere, Marco Aiello, Carol Di Perri, Davinia Fernandez-Espejo, Adrian M Owen, Andrea Soddu

Brain and Mind Institute Researchers' Publications

Progress in neuroimaging has yielded new powerful tools which, potentially, can be applied to clinical populations, improve the diagnosis of neurological disorders and predict outcome. At present, the diagnosis of consciousness disorders is limited to subjective assessment and objective measurements of behavior, with an emerging role for neuroimaging techniques. In this review we focus on white matter alterations measured using Diffusion Tensor Imaging on patients with consciousness disorders, examining the most common diffusion imaging acquisition protocols and considering the main issues related to diffusion imaging analyses. We conclude by considering some of the remaining challenges to overcome, the existing knowledge …

Bilateral Saccadic Deficits Following Large And Reversible Inactivation Of Unilateral Frontal Eye Field., Tyler R Peel, Kevin Johnston, Stephen G Lomber, Brian D Corneil

Brain and Mind Institute Researchers' Publications

Inactivation permits direct assessment of the functional contribution of a given brain area to behavior. Previous inactivation studies of the frontal eye field (FEF) have either used large permanent ablations or reversible pharmacological techniques that only inactivate a small volume of tissue. Here we evaluated the impact of large, yet reversible, FEF inactivation on visually guided, delayed, and memory-guided saccades, using cryoloops implanted in the arcuate sulcus. While FEF inactivation produced the expected triad of contralateral saccadic deficits (increased reaction time, decreased accuracy and peak velocity) and performance errors (neglect or misdirected saccades), we also found consistent increases in reaction …

Short-Duration Stimulation Of The Supplementary Eye Fields Perturbs Anti-Saccade Performance While Potentiating Contralateral Head Orienting., Brendan B Chapman, Brian D Corneil

Brain and Mind Institute Researchers' Publications

Many forms of brain stimulation utilize the notion of state dependency, whereby greater influences are observed when a given area is more engaged at the time of stimulation. Here, by delivering intracortical microstimulation (ICMS) to the supplementary eye fields (SEF) of monkeys performing interleaved pro- and anti-saccades, we show a surprising diversity of state-dependent effects of ICMS-SEF. Short-duration ICMS-SEF passed around cue presentation selectively disrupted anti-saccades by increasing reaction times and error rates bilaterally, and also recruited neck muscles, favoring contralateral head turning to a greater degree on anti-saccade trials. These results are consistent with the functional relevance of the …

An Invitation To The Study Of Brain Networks, With Some Statistical Analysis Of Thresholding Techniques, Mark Daley

Brain and Mind Institute Researchers' Publications

We provide a brief introduction to the nascent application of network theory to mesoscale networks in the human brain. Following an overview of the typical data-gathering, processing, and analysis methods employed in this field, we describe the process for inferring a graph from neural time series. A crucial step in the construction of a graph from time series is the thresholding of graph edges to ensure that the graphs represent physiological relationships rather than artifactual noise. We discuss the most popular currently employed methodologies and then introduce one of our own, based on the theory of random matrices. Finally, we …

Observing Object Lifting Errors Modulates Cortico-Spinal Excitability And Improves Object Lifting Performance., Gavin Buckingham, Jeremy D Wong, Minnie Tang, Paul L Gribble, Melvyn A Goodale

Brain and Mind Institute Researchers' Publications

Observing the actions of others has been shown to modulate cortico-spinal excitability and affect behaviour. However, the sensorimotor consequences of observing errors are not well understood. Here, participants watched actors lift identically weighted large and small cubes which typically elicit expectation-based fingertip force errors. One group of participants observed the standard overestimation and underestimation-style errors that characterise early lifts with these cubes (Error video--EV). Another group watched the same actors performing the well-adapted error-free lifts that characterise later, well-practiced lifts with these cubes (No error video--NEV). We then examined actual object lifting performance in the subjects who watched the EV …

Sign Language Ability In Young Deaf Signers Predicts Comprehension Of Written Sentences In English., Kathy N Andrew, Jennifer Hoshooley, Marc F Joanisse

Brain and Mind Institute Researchers' Publications

We investigated the robust correlation between American Sign Language (ASL) and English reading ability in 51 young deaf signers ages 7;3 to 19;0. Signers were divided into 'skilled' and 'less-skilled' signer groups based on their performance on three measures of ASL. We next assessed reading comprehension of four English sentence structures (actives, passives, pronouns, reflexive pronouns) using a sentence-to-picture-matching task. Of interest was the extent to which ASL proficiency provided a foundation for lexical and syntactic processes of English. Skilled signers outperformed less-skilled signers overall. Error analyses further indicated greater single-word recognition difficulties in less-skilled signers marked by a higher …

Links Between White Matter Microstructure And Cortisol Reactivity To Stress In Early Childhood: Evidence For Moderation By Parenting., Haroon I Sheikh, Marc F Joanisse, Sarah M Mackrell, Katie R Kryski, Heather J Smith, Shiva M Singh, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

Activity of the hypothalamic-pituitary-adrenal axis (measured via cortisol reactivity) may be a biological marker of risk for depression and anxiety, possibly even early in development. However, the structural neural correlates of early cortisol reactivity are not well known, although these would potentially inform broader models of mechanisms of risk, especially if the early environment further shapes these relationships. Therefore, we examined links between white matter architecture and young girls' cortisol reactivity and whether early caregiving moderated these links. We recruited 45 6-year-old girls based on whether they had previously shown high or low cortisol reactivity to a stress task at …

Sensitivity Of Human Auditory Cortex To Rapid Frequency Modulation Revealed By Multivariate Representational Similarity Analysis., Marc F Joanisse, Diedre D Desouza

Brain and Mind Institute Researchers' Publications

Functional Magnetic Resonance Imaging (fMRI) was used to investigate the extent, magnitude, and pattern of brain activity in response to rapid frequency-modulated sounds. We examined this by manipulating the direction (rise vs. fall) and the rate (fast vs. slow) of the apparent pitch of iterated rippled noise (IRN) bursts. Acoustic parameters were selected to capture features used in phoneme contrasts, however the stimuli themselves were not perceived as speech per se. Participants were scanned as they passively listened to sounds in an event-related paradigm. Univariate analyses revealed a greater level and extent of activation in bilateral auditory cortex in response …

Dopaminergic Medication Impairs Feedback-Based Stimulus-Response Learning But Not Response Selection In Parkinson's Disease., Andrew Vo, Nole M Hiebert, Ken N Seergobin, Stephanie Solcz, Allison Partridge, Penny A Macdonald

Brain and Mind Institute Researchers' Publications

Cognitive dysfunction is a feature of Parkinson's Disease (PD). Some cognitive functions are impaired by dopaminergic medications prescribed to address the movement symptoms that typify PD. Learning appears to be the cognitive function most frequently worsened by dopaminergic therapy. However, this result could reflect either impairments in learning (i.e., acquisition of associations among stimuli, responses, and outcomes) or deficits in performance based on learning (e.g., selecting responses). We sought to clarify the specific effects of dopaminergic medication on (a) stimulus-response association learning from outcome feedback and (b) response selection based on learning, in PD. We tested 28 PD patients on …

Rule-Based Category Learning In Children: The Role Of Age And Executive Functioning., Rahel Rabi, John Paul Minda

Brain and Mind Institute Researchers' Publications

Rule-based category learning was examined in 4-11 year-olds and adults. Participants were asked to learn a set of novel perceptual categories in a classification learning task. Categorization performance improved with age, with younger children showing the strongest rule-based deficit relative to older children and adults. Model-based analyses provided insight regarding the type of strategy being used to solve the categorization task, demonstrating that the use of the task appropriate strategy increased with age. When children and adults who identified the correct categorization rule were compared, the performance deficit was no longer evident. Executive functions were also measured. While both working …

Organizational Climate And The Theory Of Human Caring In Hospitals, Vivienne C. Meanger

2010-2016 Archived Posters

Patient care in hospitals has become perfunctory, task focused, and void of a personalized human connection, which has become an area of concern among scholars since the 1970s. This experimental, post-test only, control-group study with a purposive patient and clinical staff sample explored the relationship between human caring and patient satisfaction; and the role of leadership in transforming the organizational culture in an long term acute care hospital (LTACH) setting implanting the Magnet initiatives.

Examining The Effect Of Medical-Surgical Nurse Manager Leadership On Employee Organizational Citizenship, Cheryl B. Cullen

2010-2016 Archived Posters

An intriguing question in a hospital is “What makes one medical-surgical nursing unit more desirable to nurses, physicians, and patients than another?” This quantitative, correlational research study identified a moderately positive correlation (r = .35, p = .000 between the leadership and communication behaviors of the nurse manager and the organizational citizenship of the nurses and nursing assistants who worked on the medical-surgical nursing units studied. The social impact of this positive correlation is better patient care outcomes.

Stress: The Development And Influence On Self-Identity, Earl Grey

2010-2016 Archived Posters

Using a grounded theory methodology and constantcomparative analysis, the investigator sought to develop an empirical understanding of the experience of stress and its influence on identity development. The 23 participants, who did not meet criteria for a DSM-IV-TR diagnoses, received 10 - 60 minutes sessions of eye movement desensitization and reprocessing treatment (EMDR). EMDR treatment targets stressful memories and elicits recall of thoughts, imagery, emotions, and physical body sensations related to the stressful experience. The data from video recorded sessions provided holistic information regarding each participant’s experience and recall of stressful events. The results yielded thematic developmental patterns of thoughts, …

The Human-Animal Bond And Combat-Related Posttraumatic Stress, Melissa White

2010-2016 Archived Posters

This study explored the lived experiences of Operational Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) service members with combatrelated posttraumatic stress disorder (PTSD) symptoms who had a companion animal postdeployment. Twelve OEF and OIF veterans participated in semi-structured interviews analyzed using Moustakas’ phenomenological approach. Four themes emerged: (a) rich descriptions of deployment events, (b) the experiences of returning from a deployment, (c) participants’ perceptions on their pets’ influence on posttraumatic stress symptoms, and (d) other comments and opinions related to participants’ experiences. These findings illuminate the experience of combat-related posttraumatic stress and the importance of animals in the therapeutic …

University of Nebraska Public Policy Center: Publications

Confidentiality can both facilitate and inhibit working relationships of chaplains and mental health professionals addressing the needs of service members and veterans in the United States. Researchers conducted this study to examine opportunities for improving integration of care within the Department of Defense (DoD) and Department of Veterans Affairs (VA). Interviews were conducted with 198 chaplains and 201 mental health professionals in 33 DoD and VA facilities. Using a blended qualitative research approach, researchers identified several themes from the interviews, including recognition that integration can improve services; chaplaincy confidentiality can facilitate help seeking behavior; and mental health and chaplain confidentiality …

The Relationship Between Collective Action And Well-Being And Its Moderators: Pervasiveness Of Discrimination And Dimensions Of Action, Mindi D. Foster

Psychology Faculty Publications

Given the negative impact of perceiving gender discrimination on health (e.g., Pascoe & Smart Richman, 2009), there is a need to develop interventions to attenuate this effect; collective action may be one such intervention. Study 1 (N = 185) used an experimental paradigm to investigate whether undergraduate women in Waterloo, Ontario, Canada perceived pervasiveness of discrimination would interact with their collective action-taking to predict negative mood and well-being. Results showed that among those perceiving pervasive gender discrimination, informing friends/family and informing the media led to greater well-being than doing nothing, whereas among those perceiving gender discrimination as isolated, doing nothing …

Is Burnout A Depressive Disorder? A Reexamination With Special Focus On Atypical Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Whether burnout and depression cover the same psychopathology remains to be elucidated. To date, subtypes of depression have been overlooked in research on the burnout–depression overlap. Our aim was to estimate the prevalence of depressive disorders in workers with burnout while examining the overlap of burnout with the atypical subtype of depression. The present study included 5,575 schoolteachers (mean age = 41 years; 78% female). Burnout was assessed with the Maslach Burnout Inventory. Depression was measured with the 9-item depression scale of the Patient Health Questionnaire (PHQ-9). Atypical features of depression were examined using a dedicated module, referenced to …

Empathy As A Moderator Of Adolescent Bullying Behavior And Moral Disengagement After Controlling For Social Desirability, Amy Zelidman

Wayne State University Dissertations

The purpose of this study was to assess the moderating influence empathy has on the associations between adolescent bullying behavior and moral disengagement after controlling for social desirability (e.g., response bias). 676 students in 7th and 8th grade from a suburban middle school in Southeast Michigan participated in this study in the fall of 2012.

Results showed male respondents were more likely than female respondents to (a) report engaging in all forms of traditional bullying behavior overall, including physical, verbal, and social bullying and (b) report higher rates of physical victimization and moral disengagement. Female respondents were more likely to …

Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies, Ana Marie Daugherty

Wayne State University Dissertations

Accumulation of non-heme iron in the brain has been theorized as a cellular mechanism underlying global neural and cognitive decline in normal aging and neurodegenerative disease. Relatively few studies of brain iron in normal aging exist and extant studies are almost exclusively cross-sectional. Here, I estimated iron content via T2* and measured volumes in several brain regions in two independent samples of healthy adults. The first sample (N = 89) was measured twice with a two-year delay; and the second sample (N = 32) was assessed four times over a span of 7 years. Latent models estimated change in iron …

Coping Similarity And Psychosocial Risk Factors In Couples With Chronic Pain, Amy M. Williams

Wayne State University Dissertations

Chronic pain is an important public health problem that is associated with a host of negative individual and relationship outcomes. Chronic pain is a chronic stressor that both the individual in pain and their spouse must cope with. The current study examined how pain coping similarity within the couple predicted not only patient adjustment, but also spouse adjustment in a longitudinal study. Participants were 108 heterosexual couples in which one partner had chronic pain. The participants completed measures at 3 time points at 6 month intervals. Both the patient and spouse individually completed questionnaires pertaining to their marriage, mood, pain …
