Concerns have been growing about the veracity of psychological research. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across multiple lab sites, offers a pragmatic solution to these and other current methodological challenges. The Psychological Science Accelerator (PSA) is a distributed network of laboratories designed to enable and support crowdsourced research projects. These projects can focus on novel research questions, or attempt to replicate prior …

Impaired Object-Location Learning And Recognition Memory But Enhanced Sustained Attention In M2 Muscarinic Receptor-Deficient Mice, Carola Romberg, Susan Bartko, Jürgen Wess, Lisa M. Saksida, Timothy J. Bussey
Brain and Mind Institute Researchers' Publications
© 2018, The Author(s). Rationale: Muscarinic acetylcholine receptors are known to play key roles in mediating cognitive processes, and impaired muscarinic cholinergic neurotransmission is associated with normal ageing processes and Alzheimer’s disease. However, the specific contributions of the individual muscarinic receptor subtypes (M1–M5) to cognition are presently not well understood. Objectives: The aim of this study was to investigate the contribution of M2-type muscarinic receptor signalling to sustained attention, executive control and learning and memory. Methods: M2 receptor-deficient (M2−/−) mice were tested on a touchscreen-operated task battery testing visual discrimination, behavioural flexibility, object-location associative learning, attention and response control. Spontaneous …
Exploring The Neural Mechanisms Of Physics Learning, Jessica E. Bartley
Exploring The Neural Mechanisms Of Physics Learning, Jessica E. Bartley
FIU Electronic Theses and Dissertations
This dissertation presents a series of neuroimaging investigations and achievements that strive to deepen and broaden our understanding of human problem solving and physics learning. Neuroscience conceives of dynamic relationships between behavior, experience, and brain structure and function, but how neural changes enable human learning across classroom instruction remains an open question. At the same time, physics is a challenging area of study in which introductory students regularly struggle to achieve success across university instruction. Research and initiatives in neuroeducation promise a new understanding into the interactions between biology and education, including the neural mechanisms of learning and development. These …
Common Sense And Common Nonsense: A Conversation About Mental Attitudes, Science, And Society, Daniel S. Levine
Common Sense And Common Nonsense: A Conversation About Mental Attitudes, Science, And Society, Daniel S. Levine
Psychology Faculty Publications
Daniel S. Levine's Common Sense and Common Nonsense observes human decision making, ethics, and social organization as illuminated by the scientific disciplines of neural network theory, neuroscience, experimental psychology, and dynamical systems theory. It is a book whose aim is advocacy as well as research. Its goal is to use an understanding of our brains and minds to better operationalize Aldous Huxley's admonition to "try to be a little kinder." It wanders over examples from sociology, politics, economics, religion, literature, and many other fields but looks at all as examples of a few common themes. The "common nonsense" of the …
Validation And Optimisation Of A Touchscreen Progressive Ratio Test Of Motivation In Male Rats, Jonathan M. Hailwood, Christopher J. Heath, Trevor W. Robbins, Lisa M. Saksida, Timothy J. Bussey
Validation And Optimisation Of A Touchscreen Progressive Ratio Test Of Motivation In Male Rats, Jonathan M. Hailwood, Christopher J. Heath, Trevor W. Robbins, Lisa M. Saksida, Timothy J. Bussey
Brain and Mind Institute Researchers' Publications
© 2018, The Author(s). Rationale: Across species, effort-related motivation can be assessed by testing behaviour under a progressive ratio (PR) schedule of reinforcement. However, to date, PR tasks for rodents have been available using traditional operant response systems only. Objectives: Touchscreen operant response systems allow the assessment of behaviour in laboratory rodents, using tasks that share high face validity with the computerised assessments used in humans. Here, we sought to optimise a rat touchscreen variant of PR and validate it by assessing the effects of a number of manipulations known to affect PR performance in non-touchscreen paradigms. Methods: Separate groups …
Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia
Resting-State Functional Connectivity In Youth With Gender Dysphoria, Felix L. Garcia
Dissertations, Theses, and Capstone Projects
Current developmental models of gender identity and gender dysphoria (GD) lack sex-specific profiles of brain function that differentiate between typically-developing and cross-gender identified youth, as postulated by models like the unified theory of the origins of sex differences (Arnold, 2009) and the neurobiological theory of the origins of transsexuality (Swaab & Garcia-Falgueras, 2009). Previously, investigators have used brain imaging modalities such as Resting-State functional Magnetic Resonance Imaging (R-fMRI) to demonstrate differences in resting-state functional connectivity (RSFC) between typically-developing male and female youth, and between typically-developing and GID-diagnosed youth. In the present pilot study, I used R-fMRI to investigate differences in …

Universal Features In Phonological Neighbor Networks, Kevin S. Brown, Paul D. Allopenna, William R. Hunt, Rachael Steiner, Elliot Saltzman, Ken Mcrae, James Magnuson
Brain and Mind Institute Researchers' Publications
Human speech perception involves transforming a countinuous acoustic signal into discrete linguistically meaningful units (phonemes) while simultaneously causing a listener to activate words that are similar to the spoken utterance and to each other. The Neighborhood Activation Model posits that phonological neighbors (two forms [words] that differ by one phoneme) compete significantly for recognition as a spoken word is heard. This definition of phonological similarity can be extended to an entire corpus of forms to produce a phonological neighbor network (PNN). We study PNNs for five languages: English, Spanish, French, Dutch, and German. Consistent with previous work, we find that …
Mooney Face Stimuli For Visual Perception Research, Caspar M. Schwiedrzik, Lucia Melloni, Aaron Schurger
Mooney Face Stimuli For Visual Perception Research, Caspar M. Schwiedrzik, Lucia Melloni, Aaron Schurger
Psychology Faculty Articles and Research
In 1957, Craig Mooney published a set of human face stimuli to study perceptual closure: the formation of a coherent percept on the basis of minimal visual information. Images of this type, now known as "Mooney faces", are widely used in cognitive psychology and neuroscience because they offer a means of inducing variable perception with constant visuospatial characteristics (they are often not perceived as faces if viewed upside down). Mooney's original set of 40 stimuli has been employed in several studies. However, it is often necessary to use a much larger stimulus set. We created a new set of over …
Brazilian Jiu Jitsu: A Tool For Veteran Reassimilation, Gino L. Collura
Brazilian Jiu Jitsu: A Tool For Veteran Reassimilation, Gino L. Collura
USF Tampa Graduate Theses and Dissertations
This dissertation evaluates veteran participation in the martial art of Brazilian Jiu Jitsu (BJJ) as a tool of reassimilation for veterans suffering from anxiety, stress and/or combat PTSD associated with military deployment. From the onset of Operation Iraqi Freedom, Operation Enduring Freedom and Operation New Dawn, challenges associated with U.S. Veteran assimilation and reintegration have been increasing. Coping with long term displacement, trauma, loss, and making sense of identity shifts between being an active duty service member and civilian can often present challenges when navigating back into civilian life.
By utilizing a neuroanthropological lens, ethnographic inquiry, surveys, semi-structured interviews, and …
Longitudinal Alzheimer's Degeneration Reflects The Spatial Topography Of Cholinergic Basal Forebrain Projections, Taylor W. Schmitz, Marieke Mur, Meghmik Aghourian, Marc Andre Bedard, R. Nathan Spreng
Longitudinal Alzheimer's Degeneration Reflects The Spatial Topography Of Cholinergic Basal Forebrain Projections, Taylor W. Schmitz, Marieke Mur, Meghmik Aghourian, Marc Andre Bedard, R. Nathan Spreng
Brain and Mind Institute Researchers' Publications
© 2018 The Author(s) The cholinergic neurons of the basal forebrain (BF) provide virtually all of the brain's cortical and amygdalar cholinergic input. They are particularly vulnerable to neuropathology in early Alzheimer's disease (AD) and may trigger the emergence of neuropathology in their cortico-amygdalar projection system through cholinergic denervation and trans-synaptic spreading of misfolded proteins. We examined whether longitudinal degeneration within the BF can explain longitudinal cortico-amygdalar degeneration in older human adults with abnormal cerebrospinal fluid biomarkers of AD neuropathology. We focused on two BF subregions, which are known to innervate cortico-amygdalar regions via two distinct macroscopic cholinergic projections. To …
Effects Of Mild Traumatic Brain Injury On Ethanol Consumption And The Combined Effects On Neuroinflammation, Cognition, And Behavior In Mice, Jessica L. Hoffman
Effects Of Mild Traumatic Brain Injury On Ethanol Consumption And The Combined Effects On Neuroinflammation, Cognition, And Behavior In Mice, Jessica L. Hoffman
USF Tampa Graduate Theses and Dissertations
The relationship between alcohol consumption and traumatic brain injury (TBI) often focuses on alcohol consumption increasing the likelihood of incurring a TBI, rather than alcohol use outcomes after TBI. This focus is in part due to the large numbers of TBI patients visiting emergency rooms notable levels of alcohol in their blood. Additionally, increases in alcohol use disorders following TBI can be predicted by previous history of alcohol use. However, studies have also shown patients without a history of an alcohol use disorder can experience increases in problem drinking after single or multiple TBIs. Due to the diffuse impact of …
Abstract Concepts And Pictures Of Real-World Situations Activate One Another., Ken Mcrae, Daniel Nedjadrasul, Raymond Pau, Bethany Pui-Hei Lo, Lisa King
Abstract Concepts And Pictures Of Real-World Situations Activate One Another., Ken Mcrae, Daniel Nedjadrasul, Raymond Pau, Bethany Pui-Hei Lo, Lisa King
Brain and Mind Institute Researchers' Publications
concepts typically are defined in terms of lacking physical or perceptual referents. We argue instead that they are not devoid of perceptual information because knowledge of real-world situations is an important component of learning and using many abstract concepts. Although the relationship between perceptual information and abstract concepts is less straightforward than for concrete concepts, situation-based perceptual knowledge is part of many abstract concepts. In Experiment 1, participants made lexical decisions to abstract words that were preceded by related and unrelated pictures of situations. For example, share was preceded by a picture of two girls sharing a cob of corn. …
Selective Effects Of 5-Ht2c Receptor Modulation On Performance Of A Novel Valence-Probe Visual Discrimination Task And Probabilistic Reversal Learning In Mice, Benjamin U. Phillips, Sigma Dewan, Simon R.O. Nilsson, Trevor W. Robbins, Christopher J. Heath, Lisa M. Saksida, Timothy J. Bussey, Johan Alsiö
Selective Effects Of 5-Ht2c Receptor Modulation On Performance Of A Novel Valence-Probe Visual Discrimination Task And Probabilistic Reversal Learning In Mice, Benjamin U. Phillips, Sigma Dewan, Simon R.O. Nilsson, Trevor W. Robbins, Christopher J. Heath, Lisa M. Saksida, Timothy J. Bussey, Johan Alsiö
Brain and Mind Institute Researchers' Publications
© 2018, The Author(s). Rationale: Dysregulation of the serotonin (5-HT) system is a pathophysiological component in major depressive disorder (MDD), a condition closely associated with abnormal emotional responsivity to positive and negative feedback. However, the precise mechanism through which 5-HT tone biases feedback responsivity remains unclear. 5-HT2C receptors (5-HT2CRs) are closely linked with aspects of depressive symptomatology, including abnormalities in reinforcement processes and response to stress. Thus, we aimed to determine the impact of 5-HT2CR function on response to feedback in biased reinforcement learning. Methods: We used two touchscreen assays designed to assess the impact of positive and negative feedback …
Testing The Efficacy Of Transcranial Magnetic Stimulation (Tms) In Treating Depression In Patients With Cognitive Impairment, Daniel Robert Schaffer
Testing The Efficacy Of Transcranial Magnetic Stimulation (Tms) In Treating Depression In Patients With Cognitive Impairment, Daniel Robert Schaffer
Psychology Theses & Dissertations
The purpose of this study is to (1) examine the efficacy of Transcranial Magnetic Stimulation (TMS) in treating depression among individuals with cognitive impairment and (2) to examine if TMS is capable of facilitating cognitive improvements independent of mood improvements. Mild cognitive impairment (MCI) is often seen as a pre-clinical stage to dementia, and depressive disorders are highly prevalent among both MCI and dementia. There is a large body of research that has linked depressive disorders as a prodromal symptom of MCI and the later development of dementia. While some researchers debate whether or not this link between depression and …

IMPORTANCE There is urgent need to improve the limited prognostic accuracy of clinical instruments to predict psychosis onset in individuals at clinical high risk (CHR) for psychosis. As yet, no reliable biological marker has been established to delineate CHR individuals who will develop psychosis from those who will not. OBJECTIVES To investigate abnormalities in a graph-based gyrification connectome in the early stages of psychosis and to test the accuracy of this systems-based approach to predict a transition to psychosis among CHR individuals. DESIGN, SETTING, AND PARTICIPANTS This investigation was a cross-sectional magnetic resonance imaging (MRI) study with follow-up assessment to …
Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson
Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson
Theses & Dissertations
Multiple cancer populations frequently report cognitive impairment following treatment with chemotherapy agents (“chemo-brain”). Impaired neuropsychological performance is commonly reported in cognitive domains of attention and executive function. Understanding neural mechanisms underlying cognitive impairments is essential to developing prevention and rehabilitation strategies. Brain imaging studies frequently show chemotherapy-related impairments within the attentional control network, which is comprised of a constellation of cortical regions that govern reportedly impaired cognitive functions. In the current dissertation research, I developed a novel electrophysiology battery aimed at recording near-instantaneous neural activity within the attentional control network during cognitive task performance. Cancer patients diagnosed with hematological malignancy …
Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz
Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz
Psychology Faculty Articles and Research
Objective: We propose that clinicians can use suggestion to help treat conditions such as ADHD. Methods: We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. Results: The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Conclusion: Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential …
Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall
Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall
Psychology Faculty Publications
Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …
Modified Origins Of Cortical Projections To The Superior Colliculus In The Deaf: Dispersion Of Auditory Efferents., Blake E Butler, Julia K Sunstrum, Stephen G Lomber
Modified Origins Of Cortical Projections To The Superior Colliculus In The Deaf: Dispersion Of Auditory Efferents., Blake E Butler, Julia K Sunstrum, Stephen G Lomber
Brain and Mind Institute Researchers' Publications
Following the loss of a sensory modality, such as deafness or blindness, crossmodal plasticity is commonly identified in regions of the cerebrum that normally process the deprived modality. It has been hypothesized that significant changes in the patterns of cortical afferent and efferent projections may underlie these functional crossmodal changes. However, studies of thalamocortical and corticocortical connections have refuted this hypothesis, instead revealing a profound resilience of cortical afferent projections following deafness and blindness. This report is the first study of cortical outputs following sensory deprivation, characterizing cortical projections to the superior colliculus in mature cats (
Transcranial Direct Current Stimulation (Tdcs) Improves Performance On Spelling And Word Detection Tasks, J. Kevin Wilson
Transcranial Direct Current Stimulation (Tdcs) Improves Performance On Spelling And Word Detection Tasks, J. Kevin Wilson
Psychology ETDs
Deficits in written language involving spelling can have negative effects on a person’s education and occupation. Conventional spelling therapy is a time consuming and cost-prohibitive option, if even available, highlighting the need for improved methods for remediation. One possible way to address this need may be through the use of transcranial direct current stimulation (tDCS). This study sought to examine the effects of tDCS on performance during spelling, word detection, and facial recognition tasks. Active or sham tDCS was randomly assigned to typically functioning adults. The anode electrode was placed over Broca’s area (F7 in the 10/20 EEG system) and …
Network Specialization During Adolescence: Hippocampal Effective Connectivity In Boys And Girls, Jeffrey D. Riley, E. Elinor Chen, Jessica Winsell, Elyssia Poggi Davis, Laura M. Glynn, Tallie Z. Baram, Curt A. Sandman, Steven L. Small, Ana Solodkin

Psychology Faculty Articles and Research
Adolescence is a complex period of concurrent mental and physical development that facilitates adult functioning at multiple levels. Despite the growing number of neuroimaging studies of cognitive development in adolescence focusing on regional activation patterns, there remains a paucity of information about the functional interactions across these participating regions that are critical for cognitive functioning, including memory. The current study used structural equation modeling (SEM) to determine how interactions among brain regions critical for memory change over the course of adolescence. We obtained functional MRI in 77 individuals aged 8–16 years old, divided into younger (ages 8–10) and older (ages …

Brain and Mind Institute Researchers' Publications
Atypical sensory perception is one of the most ubiquitous symptoms of autism, including a tendency towards a local-processing bias. We investigated whether local-processing biases were associated with global-processing impairments on a global/local attentional-scope paradigm in conjunction with a composite-face task. Behavioural results were related to individuals' levels of autistic traits, specifically the Attention to Detail subscale of the Autism Quotient, and the Sensory Profile Questionnaire. Individuals showing high rates of Attention to Detail were more susceptible to global attentional-scope manipulations, suggesting that local-processing biases associated with Attention to Detail do not come at the cost of a global-processing deficit, but …

© 2018 The Author(s). Amyotrophic lateral sclerosis-frontotemporal dementia (ALS-FTD) constitutes a devastating disease spectrum characterized by 43-kDa TAR DNA-binding protein (TDP-43) pathology. Understanding how TDP-43 contributes to neurodegeneration will help direct therapeutic efforts. Here we have created a TDP-43 knock-in mouse with a human-equivalent mutation in the endogenous mouse Tardbp gene. TDP-43Q331K mice demonstrate cognitive dysfunction and a paucity of parvalbumin interneurons. Critically, TDP-43 autoregulation is perturbed, leading to a gain of TDP-43 function and altered splicing of Mapt, another pivotal dementia-associated gene. Furthermore, a new approach to stratify transcriptomic data by phenotype in differentially affected mutant mice revealed 471 …
Addressing Hydrocephaly In Viet Nam: A Plausible Prevention And Intervention Medical Support Program Proposal, Chelle Mcintyre-Brewer
Addressing Hydrocephaly In Viet Nam: A Plausible Prevention And Intervention Medical Support Program Proposal, Chelle Mcintyre-Brewer
UNO Student Research and Creative Activity Fair
Families affected by hydrocephalus in Viet Nam have few options for sustainable treatment for a myriad of reasons, primarily centering on barriers to care prevalent to minority, underserved, and economically disadvantaged populations. High morbidity and abandonment rates often result from these circumstances. An interdisciplinary examination of the factors contributing to causal concerns reveals unique cultural considerations, language and literacy barriers, ethnic and geographic differences, as well as economic and governmental issues greatly impacting patient outcome for this condition. The author contends that a program that addresses sociological concerns, along with the medical treatment of the patient, proffers the opportunity for …

Cortical And Thalamic Connectivity To The Second Auditory Cortex Of The Cat Is Resilient To The Onset Of Deafness., Blake E Butler, Alexandra De La Rua, Taylor Ward-Able, Stephen G Lomber
Brain and Mind Institute Researchers' Publications
It has been well established that following sensory loss, cortical areas that would normally be involved in perceiving stimuli in the absent modality are recruited to subserve the remaining senses. Despite this compensatory functional reorganization, there is little evidence to date for any substantial change in the patterns of anatomical connectivity between sensory cortices. However, while many auditory areas are contracted in the deaf, the second auditory cortex (A2) of the cat undergoes a volumetric expansion following hearing loss, suggesting this cortical area may demonstrate a region-specific pattern of structural reorganization. To address this hypothesis, and to complement existing literature …

BACKGROUND: Optimizing early nutritional intake in preterm neonates may promote brain health and neurodevelopment through enhanced brain maturation. Our objectives were (1) to determine the association of energy and macronutrient intake in the first 2 weeks of life with regional and total brain growth and white matter (WM) maturation, assessed by 3 serial MRI scans in preterm neonates; (2) to examine how critical illness modifies this association; and (3) to investigate the relationship with neurodevelopmental outcomes.
METHODS: Forty-nine preterm neonates (21 boys, median [interquartile range] gestational age: 27.6 [2.3] weeks) were scanned serially at the following median postmenstrual weeks: 29.4, …

Brain and Mind Institute Researchers' Publications
© 2017, The Author(s). The vestibulo-ocular reflex (VOR) adaptation is an ideal model for investigating how the neurosteroid 17 beta-estradiol (E2) contributes to the modification of behavior by regulating synaptic activities. We hypothesized that E2 impacts VOR adaptation by affecting cerebellar synaptic plasticity at the parallel fiber–Purkinje cell (PF) synapse. To verify this hypothesis, we investigated the acute effect of blocking E2 synthesis on gain increases and decreases in adaptation of the VOR in male rats using an oral dose (2.5 mg/kg) of the aromatase inhibitor letrozole. We also assessed the effect of letrozole on synaptic plasticity at the PF …

Psychology: Faculty Scholarship
Despite accruing evidence showing that positive emotions facilitate stress recovery, the neural basis for this effect remains unclear. To identify the underlying mechanism, we compared stress recovery for people reflecting on a stressor while in a positive emotional context with that for people in a neutral context. While blood–oxygen-level dependent data were being collected, participants (N = 43) performed a stressful anagram task, which was followed by a recovery period during which they reflected on the stressor while watching a positive or neutral video. Participants also reported positive and negative emotions throughout the task as well as retrospective thoughts …
