College Students' Relationship With Attention Deficit Hyperactivity Disorder And Learning Accommodations At The University Of Nebraska-Lincoln, Brianna Danehey, Kim Hansen Dr., Chelsea Witt Dr.
College Students' Relationship With Attention Deficit Hyperactivity Disorder And Learning Accommodations At The University Of Nebraska-Lincoln, Brianna Danehey, Kim Hansen Dr., Chelsea Witt Dr.
Honors Theses
Attention deficit hyperactivity disorder (ADHD) can provide many challenges for college students due to difficulties focusing, multi-tasking, and staying organized. Colleges are required to offer academic accommodations to students with disabilities in an attempt to provide students with an equitable learning environment. However, accommodations may be ineffective if they are highly unattainable, unused by the student once granted, or hindered by university faculty.
The objective of this study was to identify barriers to receiving effective and beneficial academic accommodations for individuals with ADHD at the University level and to provide insight into college students' knowledge and relationships relating to the …

The Role Of Dentate Gyrus Pituitary Adenylate Cyclase Activating Polypeptide (Pacap) In Contextual Fear Discrimination, Samantha Kelly Moriarty
The Role Of Dentate Gyrus Pituitary Adenylate Cyclase Activating Polypeptide (Pacap) In Contextual Fear Discrimination, Samantha Kelly Moriarty
Graduate College Dissertations and Theses
When dysregulated, neural systems important for fear behaviors can contribute to mental health disorders such as anxiety, phobias, and post-traumatic stress disorder (PTSD). In PTSD, a myriad of symptoms is possible, but a hallmark feature of the disorder is generalizing fear. This occurs when fear is experienced inappropriately in relation to the environment or circumstances. To study this behavior in rodent models, contextual fear conditioning is used. Contextual fear conditioning is a learning theory preparation where rodents are conditioned with an aversive stimulus such as foot-shock in one distinct context (A), while concurrently being exposed to a safe context (B). …
Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra
Assessing The Impact Of Lipopolysaccharide On Learning And Memory In Rats, Anahat Luthra
Undergraduate Student Research Internships Conference
The immune system and the central nervous system (CNS) have a bi-direction relationship, modulating one another.4 Proinflammatory cytokines released from CNS immune cells have an impact on cognitive processes such as learning and memory.1 Liposaccharide (LPS), a cell wall component of Gram-negative bacteria, which is used to activate proinflammatory cytokine release has been found to impact learning and memory processes, such as in the anticipatory nausea paradigm (ANP).2 Anticipatory nausea and vomiting is that which may occur before a chemotherapy treatment session begins in a patient who has had chemotherapy before. It is caused by triggers like …
Testing Models Of Context-Dependent Outcome Encoding In Reinforcement Learning, William M. Hayes Iv
Testing Models Of Context-Dependent Outcome Encoding In Reinforcement Learning, William M. Hayes Iv
Theses and Dissertations
Previous studies of reinforcement learning (RL) have established that choice outcomes are encoded in a context-dependent fashion. Several computational models have been proposed to explain context-dependent encoding, including reference point centering and range adaptation models. The former assumes that outcomes are centered around a running estimate of the average reward in each choice context, while the latter assumes that outcomes are compared to the minimum reward and then scaled by an estimate of the range of outcomes in each choice context. However, there are other computational mechanisms that can explain context dependence in RL. In the present study, a frequency …
Parent Reports Of Executive Functions In Students With Learning Disability, Jane Roitsch, Annemarie L. Horn, Lisa Morin
Parent Reports Of Executive Functions In Students With Learning Disability, Jane Roitsch, Annemarie L. Horn, Lisa Morin
Communication Disorders & Special Education Faculty Publications
This study examines the results of the Behavior Rating Inventory of Executive Function (BRIEF-2) (Gioia et al., 2015) reported by parents of children with Specific Learning Disability (LD) and/or other comorbid disabilities. LD is most notably associated with comorbid attention deficit hyperactivity disorder (ADHD) (Alloway & Stein, 2014; Westby &Watson, 2004; Willcutt et al., 2013). A total of 43 parents completed the BRIEF-2 rating scale. Findings suggest children with LD and ADHD display greater challenges with inhibition, working memory, planning, along with greater challenges in organization and metacognition. Parents of children with LD reported their children have greater levels of …
The Impact Of Levodopa Administration On Learning From Short-Term And Long-Term Action Consequences: A Paradigm Validation., Masood Rezaei
The Impact Of Levodopa Administration On Learning From Short-Term And Long-Term Action Consequences: A Paradigm Validation., Masood Rezaei
Electronic Thesis and Dissertation Repository
Behavioral and neuroimaging studies have identified two valuation systems in the human brain for controlling behavior known as model-free (MF) and model-based (MB). MF is based on immediate evaluation and MB is based on long-term evaluation of the outcome of our decisions. Previous studies suggest that dopamine baseline activity may play an important role in the balance between the two systems and determine how they compete or interact in controlling our actions. The overarching aims of this study is to investigate the impact of levodopa administration on learning from immediate and long-term action consequences, and to dissociate the role of …
Striatum-Mediated Deficits In Stimulus-Response Learning And Decision-Making In Ocd, Nole M. Hiebert, Marc R. Lawrence, Hooman Ganjavi, Mark Watling, Adrian M. Owen, Ken N. Seergobin, Penny A. Macdonald
Striatum-Mediated Deficits In Stimulus-Response Learning And Decision-Making In Ocd, Nole M. Hiebert, Marc R. Lawrence, Hooman Ganjavi, Mark Watling, Adrian M. Owen, Ken N. Seergobin, Penny A. Macdonald
Brain and Mind Institute Researchers' Publications
© Copyright © 2020 Hiebert, Lawrence, Ganjavi, Watling, Owen, Seergobin and MacDonald. Obsessive compulsive disorder (OCD) is a prevalent psychiatric disorder characterized by obsessions and compulsions. Studies investigating symptomatology and cognitive deficits in OCD frequently implicate the striatum. The aim of this study was to explore striatum-mediated cognitive deficits in patients with OCD as they complete a stimulus-response learning task previously shown to differentially rely on the dorsal (DS) and ventral striatum (VS). We hypothesized that patients with OCD will show both impaired decision-making and learning, coupled with reduced task-relevant activity in DS and VS, respectively, compared to healthy controls. …
The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer
The Effect Of Retrieval Practice On Vocabulary Learning For Children Who Are Deaf Or Hard Of Hearing, Casey Krauss Reimer
Arts & Sciences Electronic Theses and Dissertations
The goal of the current study was to determine if students who are deaf or hard of hearing (d/hh) would learn more new vocabulary words through the use of retrieval practice than repeated exposure (repeated study). No studies to date have used this cognitive strategy—retrieval practice—with children who are d/hh. Previous studies have shown that children with hearing loss struggle with learning vocabulary words. This deficit can negatively affect language development, reading outcomes, and overall academic success. Few studies have investigated specific interventions to address the poor vocabulary development for children with hearing loss. The current study investigated retrieval practice …
Translational Tests Involving Non-Reward: Methodological Considerations, Benjamin U. Phillips, Laura Lopez-Cruz, Lisa M. Saksida, Timothy J. Bussey
Translational Tests Involving Non-Reward: Methodological Considerations, Benjamin U. Phillips, Laura Lopez-Cruz, Lisa M. Saksida, Timothy J. Bussey
Brain and Mind Institute Researchers' Publications
© 2018, The Author(s). This review is concerned with methods for assessing the processing of unrewarded responses in experimental animals and the mechanisms underlying performance of these tasks. A number of clinical populations, including Parkinson’s disease, depression, compulsive disorders, and schizophrenia demonstrate either abnormal processing or learning from non-rewarded responses in laboratory-based reinforcement learning tasks. These effects are hypothesized to result from disturbances in modulatory neurotransmitter systems, including dopamine and serotonin. Parallel work in experimental animals has revealed consistent behavioral patterns associated with non-reward and, consistent with the human literature, modulatory roles for specific neurotransmitters. Classical tests involving an important …
Second Language Acquisition And Acculturation Differences Between Immigrants And Refugees, Ali Jasemi
Second Language Acquisition And Acculturation Differences Between Immigrants And Refugees, Ali Jasemi
Theses and Dissertations (Comprehensive)
The main difference between refugees and immigrants lies in the reason for their migration. Economic immigrants migrate to other countries voluntarily, while refugees are forced to leave their countries due to fear of death or persecution (UNHCR, 2018). Such fears may lead to psychological trauma among refugees. Research has shown that the presence of trauma can negatively impact language learning (Iversen, Sveaass, & Morken, 2014), which may have important implications for both second language (L2) acquisition and acculturation, particularly in refugees. In addition, strong linguistic abilities in a first language (L1) may be beneficial to acquire other languages (Cook, 2003). …
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
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 …
Standing And Dynamic Sitting In The University Classroom, Siobhan Smith
Standing And Dynamic Sitting In The University Classroom, Siobhan Smith
Electronic Thesis and Dissertation Repository
Students almost exclusively sit in class, which translates to large amounts of forced sedentary behaviour and this in turn may have negative health consequences. The effect alternative postures have on classroom performance of university students remains unknown.
Using a randomized counterbalanced design, pilot study 1 (N=40) and 2 (N=20) investigated the effect of alternative postures on 3-minute and 50-minute classroom performance, respectively. In study 3, university students’ (N=1005) and faculty (N=218) acceptability to alternative workstations in the university classroom was assessed using a mixed method approach.
This thesis provides preliminary evidence that there is no difference between classic sitting, dynamic …
Vocabulary Learning Benefits From Rem After Slow-Wave Sleep., Laura J Batterink, Carmen E Westerberg, Ken A Paller
Vocabulary Learning Benefits From Rem After Slow-Wave Sleep., Laura J Batterink, Carmen E Westerberg, Ken A Paller
Brain and Mind Institute Researchers' Publications
Memory reactivation during slow-wave sleep (SWS) influences the consolidation of recently acquired knowledge. This reactivation occurs spontaneously during sleep but can also be triggered by presenting learning-related cues, a technique known as targeted memory reactivation (TMR). Here we examined whether TMR can improve vocabulary learning. Participants learned the meanings of 60 novel words. Auditory cues for half the words were subsequently presented during SWS in an afternoon nap. Memory performance for cued versus uncued words did not differ at the group level but was systematically influenced by REM sleep duration. Participants who obtained relatively greater amounts of REM showed a …
Roles Of Gabab, Muscarinic And Nicotinic Receptor Signaling In The Acquisition And Expression Of Fructose And Fat-Conditioned Flavor Preferences And Acquisition Of Quinine-Conditioned Flavor Avoidances In Rats, Francis M. Rotella
Dissertations, Theses, and Capstone Projects
In addition to increased intake of sweet solutions by mammals, learning, particularly classically-conditioned “Pavlovian-like” learning, also plays an important role. An orosensory conditioned flavor preference (CFP) can be elicited by pairing one novel flavor (conditioned stimulus, CS+) with a fructose solution and a second novel flavor (CS-) with a saccharin solution. Rats will prefer the CS+ flavor in a subsequent 2-bottle choice test with both flavors mixed in saccharin. Previous pharmacological analyses revealed that systemic administration of dopamine (DA) D1 and D2 as well as NMDA, but not opioid, receptor antagonists eliminated the acquisition (learning) of fructose-CFP. Further, expression of …
Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink
Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink
Brain and Mind Institute Researchers' Publications
The identification of words in continuous speech, known as speech segmentation, is a critical early step in language acquisition. This process is partially supported by statistical learning, the ability to extract patterns from the environment. Given that speech segmentation represents a potential bottleneck for language acquisition, patterns in speech may be extracted very rapidly, without extensive exposure. This hypothesis was examined by exposing participants to continuous speech streams composed of novel repeating nonsense words. Learning was measured on-line using a reaction time task. After merely one exposure to an embedded novel word, learners demonstrated significant learning effects, as revealed by …
Online Neural Monitoring Of Statistical Learning., Laura J Batterink, Ken A Paller
Online Neural Monitoring Of Statistical Learning., Laura J Batterink, Ken A Paller
Brain and Mind Institute Researchers' Publications
The extraction of patterns in the environment plays a critical role in many types of human learning, from motor skills to language acquisition. This process is known as statistical learning. Here we propose that statistical learning has two dissociable components: (1) perceptual binding of individual stimulus units into integrated composites and (2) storing those integrated representations for later use. Statistical learning is typically assessed using post-learning tasks, such that the two components are conflated. Our goal was to characterize the online perceptual component of statistical learning. Participants were exposed to a structured stream of repeating trisyllabic nonsense words and a …
Learning And Working Together: Invoking Systems’ Change Through Inter-Organizational Collaborative Principles And A Learning Community Framework, Brandon Hey
Theses and Dissertations (Comprehensive)
Local communities face significant challenges such as increased inequality, immigration, and global climate change. In order to address these challenges whole cities have to innovate and learn together. In this thesis, I introduce the Learning Community (LC) model, a new way of collaborating and creating collective impact that emphasizes learning, alongside collective impact, as a central strategy to addressing complex social challenges. In a LC, members value the continuous pursuit of knowledge, feedback, and experimentation as well as the flow of information and resources between academic institutions and practice groups. The value of learning is built into key structures …
Neural Measures Reveal Implicit Learning During Language Processing., Laura J Batterink, Larry Y Cheng, Ken A Paller
Neural Measures Reveal Implicit Learning During Language Processing., Laura J Batterink, Larry Y Cheng, Ken A Paller
Brain and Mind Institute Researchers' Publications
Language input is highly variable; phonological, lexical, and syntactic features vary systematically across different speakers, geographic regions, and social contexts. Previous evidence shows that language users are sensitive to these contextual changes and that they can rapidly adapt to local regularities. For example, listeners quickly adjust to accented speech, facilitating comprehension. It has been proposed that this type of adaptation is a form of implicit learning. This study examined a similar type of adaptation, syntactic adaptation, to address two issues: (1) whether language comprehenders are sensitive to a subtle probabilistic contingency between an extraneous feature (font color) and syntactic structure …

This report discusses the development of a Portable Sensory Room to be used at Newland Elementary School in Huntington Beach. Newland Elementary has an exceptional Special Needs program that teaches the children with the most severe cases of autism in its school district. People with autism typically also have sensory processing disorders, which can be extremely disruptive for a child’s development and can make it difficult for a child to be able to concentrate long enough to gain necessary life skills. The idea behind a Sensory Rooms is to create a place to calm the students and to expose them …
Personality Affects Learning And Trade-Offs Between Private And Social Information In Guppies, Poecilia Reticulate, Larissa Trompf, Culum Brown
Personality Affects Learning And Trade-Offs Between Private And Social Information In Guppies, Poecilia Reticulate, Larissa Trompf, Culum Brown
Culum Brown, PhD
The acquisition of information such as the location and quality of food, mates or shelter is a key survival requirement for animals. Individuals can acquire information through personal experience (private information) or through observing and interacting with others (social information). Environmental spatial and temporal heterogeneity can mean that sometimes social information conflicts with private knowledge. We tested how personality affected the importance placed on public versus private information in wild female guppies when these two information sources came into conflict. We found that boldness and sociality affected decisions to use conflicting social and private information. Bolder females used social information …
Functional Plasticity In Somatosensory Cortex Supports Motor Learning By Observing., Heather R Mcgregor, Joshua G A Cashaback, Paul L Gribble
Functional Plasticity In Somatosensory Cortex Supports Motor Learning By Observing., Heather R Mcgregor, Joshua G A Cashaback, Paul L Gribble
Brain and Mind Institute Researchers' Publications
An influential idea in neuroscience is that the sensory-motor system is activated when observing the actions of others [1, 2]. This idea has recently been extended to motor learning, in which observation results in sensory-motor plasticity and behavioral changes in both motor and somatosensory domains [3-9]. However, it is unclear how the brain maps visual information onto motor circuits for learning. Here we test the idea that the somatosensory system, and specifically primary somatosensory cortex (S1), plays a role in motor learning by observing. In experiment 1, we applied stimulation to the median nerve to occupy the somatosensory system with …
Category Learning In Older Adulthood: A Study Of The Shepard, Hovland, And Jenkins (1961) Tasks., Rahel Rabi, John Paul Minda
Category Learning In Older Adulthood: A Study Of The Shepard, Hovland, And Jenkins (1961) Tasks., Rahel Rabi, John Paul Minda
Brain and Mind Institute Researchers' Publications
Shepard, Hovland, and Jenkins (1961) examined the categorization abilities of younger adults using tasks involving single-dimensional rule learning, disjunctive rule learning, and family resemblance learning. The current study examined category learning in older adults using this well-known category set. Older adults, like younger adults, found category tasks with a single relevant dimension the easiest to learn. In contrast to younger adults, older adults found complex disjunctive rule-based categories harder to learn than family resemblance based categories. Disjunctive rule-based category learning appeared to be the most difficult for older adults to learn because this category set placed the heaviest demands on …
Sensory Plasticity In Human Motor Learning., David J Ostry, Paul L Gribble
Sensory Plasticity In Human Motor Learning., David J Ostry, Paul L Gribble
Brain and Mind Institute Researchers' Publications
There is accumulating evidence from behavioral, neurophysiological, and neuroimaging studies that the acquisition of motor skills involves both perceptual and motor learning. Perceptual learning alters movements, motor learning, and motor networks of the brain. Motor learning changes perceptual function and the sensory circuits of the brain. Here, we review studies of both human limb movement and speech that indicate that plasticity in sensory and motor systems is reciprocally linked. Taken together, this points to an approach to motor learning in which perceptual learning and sensory plasticity have a fundamental role.
Changes In Visual And Sensory-Motor Resting-State Functional Connectivity Support Motor Learning By Observing., Heather R Mcgregor, Paul L Gribble
Changes In Visual And Sensory-Motor Resting-State Functional Connectivity Support Motor Learning By Observing., Heather R Mcgregor, Paul L Gribble
Brain and Mind Institute Researchers' Publications
Motor learning occurs not only through direct first-hand experience but also through observation (Mattar AA, Gribble PL. Neuron 46: 153-160, 2005). When observing the actions of others, we activate many of the same brain regions involved in performing those actions ourselves (Malfait N, Valyear KF, Culham JC, Anton JL, Brown LE, Gribble PL. J Cogn Neurosci 22: 1493-1503, 2010). Links between neural systems for vision and action have been reported in neurophysiological (Strafella AP, Paus T. Neuroreport 11: 2289-2292, 2000; Watkins KE, Strafella AP, Paus T. Neuropsychologia 41: 989-994, 2003), brain imaging (Buccino G, Binkofski F, Fink GR, Fadiga L, …

Embracing Multiple Definitions Of Learning, Andrew B. Barron, Eileen A. Hebets, Thomas A. Cleland, Courtney L. Fitzpatrick, Mark E. Hauber, Jeffrey R. Stevens
Eileen Hebets Publications
Definitions of learning vary widely across disciplines, driven largely by different approaches used to assess its occurrence. These definitions can be better reconciled with each other if each is recognized as coherent with a common conceptualization of learning, while appreciating the practical utility of different learning definitions in different contexts.
Learning is a major focus of research in psychology, neuro- science, behavioral ecology, evolutionary theory, and computer science, as well as in many other disciplines. Despite its conceptual prevalence, definitions of learning differ enormously both within and between these disciplines, and new definitions continue to be proposed [1]. Ongoing disputes …
Connectionist Perspectives On Language Learning, Representation And Processing., Marc F Joanisse, James L Mcclelland
Connectionist Perspectives On Language Learning, Representation And Processing., Marc F Joanisse, James L Mcclelland
Brain and Mind Institute Researchers' Publications
The field of formal linguistics was founded on the premise that language is mentally represented as a deterministic symbolic grammar. While this approach has captured many important characteristics of the world's languages, it has also led to a tendency to focus theoretical questions on the correct formalization of grammatical rules while also de-emphasizing the role of learning and statistics in language development and processing. In this review we present a different approach to language research that has emerged from the parallel distributed processing or 'connectionist' enterprise. In the connectionist framework, mental operations are studied by simulating learning and processing within …
Motor Skill Learning Between Selection And Execution., Jörn Diedrichsen, Katja Kornysheva
Motor Skill Learning Between Selection And Execution., Jörn Diedrichsen, Katja Kornysheva
Brain and Mind Institute Researchers' Publications
Learning motor skills evolves from the effortful selection of single movement elements to their combined fast and accurate production. We review recent trends in the study of skill learning which suggest a hierarchical organization of the representations that underlie such expert performance, with premotor areas encoding short sequential movement elements (chunks) or particular component features (timing/spatial organization). This hierarchical representation allows the system to utilize elements of well-learned skills in a flexible manner. One neural correlate of skill development is the emergence of specialized neural circuits that can produce the required elements in a stable and invariant fashion. We discuss …
Behavioral Effects Of Fluoxetine On Aggression And Associative Learning In Betta Splendens, Benjamin Eisenreich
Behavioral Effects Of Fluoxetine On Aggression And Associative Learning In Betta Splendens, Benjamin Eisenreich
Graduate Student Theses, Dissertations, & Professional Papers
While the link between serotonin and the behaviors of aggression and learning has been elucidated, few studies have examined the impact serotonin has on learning for aggressive rewards. In particular, the SSRI fluoxetine has been demonstrated to reduce aggression as well the acquisition of instrumental responding for rewards indicating that this drugs behavioral effect may be related to motivational processes important for learning. To examine the relationship between fluoxetine and motivational process important for learning, two experiments were conducted using Betta splendens, a species well known for their robust aggressive response and drive to engage in aggressive behaviors, to examine …
