Factor Structure Of The Cpt-Ii, Mary Vertinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study investigates the factor structure of the Conners' Continuous Performance Test-II (CPT-II) in four pediatric samples of participants: (a) patients with traumatic brain injury, (b) healthy controls, (c) patients with various clinical diagnoses, and (d) all of the previously mentioned subjects combined. Confirmatory factor analyses (CFA) were used to investigate a one-, three- and four-factor model fit of the data. None of the models examined were an adequate fit for the data; however, it appears that the four-factor model seemed to be the best fitting of the models examined. Failure to find reasonably adequate fit precluded further analyses.

"In 1965, Hans Kornhuber and Luder Deecke made a discovery that greatly influenced the study of voluntary action. Using electroencephalography (EEG), they showed that when aligning some tens of trials to movement onset and averaging, a slowly decreasing electrical potential emerges over central regions of the brain. It starts 1 second ( s) or so before the onset of the voluntary action1 and continues until shortly after the action begins. They termed this the Bereitschaftspotential, or readiness potential (RP; Kornhuber & Deecke, 1965).2 This became the first well-established neural marker of voluntary action. In that, the RP allowed for more …

Head Impact Exposure In Male And Female Collegiate Ice Hockey Players, Bethany J. Wilcox, Jonathan G. Beckwith, Richard M. Greenwald, Jeffrey J. Chu, Thomas W. Mcallister, Laura A. Flashman, Arthur C. Maerlender, Ann-Christine Duhaime, Joseph J. Crisco

Department of Psychology: Faculty Publications

The purpose of this study was to quantify head impact exposure (frequency, location and magnitude of head impacts) for individual male and female collegiate ice hockey players and to investigate differences in exposure by sex, player position, session type, and team. Ninety-nine (41 male, 58 female) players were enrolled and 37,411 impacts were recorded over three seasons. Frequency of impacts varied significantly by sex (males: 287 per season, females: 170, p < 0.001) and helmet impact location (p < 0.001) but not by player position (p = 0.088). Head impact frequency also varied by session type; both male and female players sustained more impacts in games than in practices (p < 0.001), however the magnitude of impacts did not differ between session types. There was no difference in 95th percentile peak linear acceleration between sexes (males: 41.6 g, females: 40.8 g), but 95th percentile peak rotational acceleration and HITsp (a composite severity measure) were greater for males than females (4424, 3409 rad/s2, and 25.6, 22.3, respectively). Impacts to the back of the helmet resulted in the greatest 95th percentile peak linear accelerations for males (45.2 g) and females (50.4 g), while impacts to the side and back of the head were associated with the greatest 95th percentile peak rotational accelerations (males: 4719, 4256 rad/sec², females: 3567, 3784 rad/sec², respectively). It has been proposed that reducing an individual’s head impact exposure is a practical approach for reducing the risk of …

Educators' Knowledge Of And Attitudes Toward Concussions And The New Jersey Concussion Law, Einat Katz-Delong

PCOM Psychology Dissertations

Recent media attention, lawsuits from retiring athletes, and the early retirement of famous athletes have increased public awareness of sports-related head injuries. High school student athletes are more susceptible to concussions than older athletes. Athletes suffering from concussions may experience long-lasting effects on their lives, particularly in cognitive, emotional, and school functioning. Given the increased rates of concussions and their ramifications, state governments and the federal government have taken action. Beginning with the start of the 2011–2012 school year, the state of New Jersey has implemented legislation that requires all school districts with interscholastic sports programs to develop a written …

Parkinson's Diagnosis From The Caregiver's Perspective, Helen Maree Bradley

Theses : Honours

Parkinson’s disease (Parkinson’s) is a progressive neurodegenerative disorder. The irreversible and accumulating disability experienced means that people with Parkinson’s progressively lose their autonomy, eventually requiring complete care. Consequently, Parkinson’s significantly impacts sufferers and the people who care for them. Informal care, predominantly provided by female spouses becomes exceptionally demanding over time, and caregivers experience significant morbidity. Stress manifests across all stages of the caregiving trajectory, with diagnosis reported as a particularly stressful period for caregivers; however, few attempts have been made to understand what makes it stressful. The current study explored female spousal caregivers’ subjective experience of the Parkinson’s diagnosis, …

Residual Fmri Sensitivity For Identity Changes In Acquired Prosopagnosia, Christopher J. Fox, Giuseppe Iaria, Bradley C. Duchaine, Jason J. S. Barton

Dartmouth Scholarship

While a network of cortical regions contribute to face processing, the lesions in acquired prosopagnosia are highly variable, and likely result in different combinations of spared and affected regions of this network. To assess the residual functional sensitivities of spared regions in prosopagnosia, we designed a rapid event-related functional magnetic resonance imaging (fMRI) experiment that included pairs of faces with same or different identities and same or different expressions. By measuring the release from adaptation to these facial changes we determined the residual sensitivity of face-selective regions-of-interest. We tested three patients with acquired prosopagnosia, and all three of these patients …

Positive Clinical Neuroscience: Explorations In Positive Neurology, N. Kapur, J. Cole, T. Manly, Indre Viskontas, A. Ninteman, L. Hasher, A. Pascual-Leone

Psychology

Disorders of the brain and its sensory organs have traditionally been associated with deficits in movement, perception, cognition, emotion, and behavior. It is increasingly evident, however, that positive phenomena may also occur in such conditions, with implications for the individual, science, medicine, and for society. This article provides a selective review of such positive phenomena – enhanced function after brain lesions, better-than-normal performance in people with sensory loss, creativity associated with neurological disease, and enhanced performance associated with aging. We propose that, akin to the well-established field of positive psychology and the emerging field of positive clinical psychology, the nascent …

Assistive Technology: Fixing Humans, Petros J. Katsioloudis, Millie Jones

STEMPS Faculty Publications

The need for assistive technology--technology that assists persons with disabilities--is great. At no time has there been a greater need to provide assistive technologies than to assist the thousands of military veterans returning home from the Middle East with a range of physical and mental disabilities. Mobility impairment is a significant concern for many returning veterans. Assistive technologies are playing a major role in assisting war veterans returning with physical limitations through the loss of a limb or, in many cases, several limbs. This article presents the history and background of assistive technology and how mobile- and computer-assistive technologies can …

Spectrum Of Acute Clinical Characteristics Of Diagnosed Concussions In College Athletes Wearing Instrumented Helmets, Ann-Christine Duhaime,, Jonathan G. Beckwith, Arthur C. Maerlender, Thomas W. Mcallister, Joseph J. Crisco, Stefan M. Duma, P. Gunnar Brolinson, Steven Rowson, Laura A. Flashman, Jeffrey J. Chu, Richard M. Greenwald

Department of Psychology: Faculty Publications

Object. Concussive head injuries have received much attention in the medical and public arenas, as concerns have been raised about the potential shortand long-term consequences of injuries sustained in sports and other activities. While many student athletes have required evaluation after concussion, the exact definition of concussion has varied among disciplines and over time. The authors used data gathered as part of a multiinstitutional longitudinal study of the biomechanics of head impacts in helmeted collegiate athletes to characterize what signs, symptoms, and clinical histories were used to designate players as having sustained concussions.

Methods. Players on 3 college …

Neuroscience Of Personality: Principles Of The Psyche As A Living System, Dario Nardi

Systems Science Friday Noon Seminar Series

The brain is a complex living system. Using colorful slides and anecdotes, Dario Nardi, PhD will overview his hands-on research of the past 5 years in his social neuroscience lab using EEG technology to better understand the neocortex. He spends 2 to 3 hours with each subject, offering a variety of tasks from solo activities like meditating, drawing, and recalling to social activities like poker and speed-dating. The results are in. The neocortex relies upon a dynamic of modules, circuits, and holistic modes to continuously coordinate with the environment in both a top-down and a bottom-up manner. Moreover, individual differences …

Purging Of Memories From Conscious Awareness Tracked In The Human Brain, Benjamin Levy, Michael C. Anderson

Psychology

Understanding the neural basis of conscious experience and its regulation are fundamental goals of science. While recent research has made substantial progress in identifying the neural correlates of conscious experiences, it remains unclear how individuals exert control over the contents of awareness. In particular, can a memory that has entered the aware state be purged from consciousness if it is not currently desired? Here we tracked the correlates of consciousness in humans using functional magnetic resonance imaging and demonstrated the involvement of a downregulation mechanism that purges contents from conscious awareness. When individuals tried to prevent the retrieval of a …

Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried

Psychology

Episodic memory, which depends critically on the integrity of the medial temporal lobe (MTL), has been described as ‘‘mental time travel’’ in which the rememberer ‘‘jumps back in time.’’ The neural mechanism underlying this ability remains elusive. Mathematical and computational models of performance in episodic memory tasks provide a specific hypothesis regarding the computation that supports such a jump back in time. The models suggest that a representation of temporal context, a representation that changes gradually over macroscopic periods of time, is the cue for episodic recall. According to these models, a jump back in time corresponds to a stimulus …

Contrasting Effects Of Errorless Naming Treatment And Gestural Facilitation For Word Retrieval In Aphasia, Anastasia M. Raymer, Beth Mchose, Kimberly G. Smith, Lisa Iman, Alexis Ambrose, Colleen Casselton

Communication Disorders & Special Education Faculty Publications

Purpose- We compared the effects of two treatments for aphasic word retrieval impairments, errorless naming treatment (ENT) and gestural facilitation of naming (GES), within the same individuals, anticipating that the use of gesture would enhance the effect of treatment over errorless treatment alone. In addition to picture naming, we evaluated results for other outcome measures that were largely untested in earlier ENT studies.

Methods- In a single participant crossover treatment design, we examined the effects of ENT and GES in eight individuals with stroke-induced aphasia and word retrieval impairments (three semantic anomia, five phonological anomia) in counterbalanced phases across participants. …

Improving Function In Age-Related Macular Degeneration: Design And Methods Of A Randomized Clinical Trial., Barry W Rovner, Robin J Casten, Mark T Hegel, Robert W Massof, Benjamin E Leiby, William S Tasman

Department of Psychiatry and Human Behavior Faculty Papers

Age-Related Macular Degeneration (AMD) is the leading cause of severe vision loss in older adults and impairs the ability to read, drive, and live independently and increases the risk for depression, falls, and earlier mortality. Although new medical treatments have improved AMD's prognosis, vision-related disability remains a major public health problem. Improving Function in AMD (IF-AMD) is a two-group randomized, parallel design, controlled clinical trial that compares the efficacy of Problem-Solving Therapy (PST) with Supportive Therapy (ST) (an attention control treatment) to improve vision function in 240 patients with AMD. PST and ST therapists deliver 6 one-hour respective treatment sessions …

Anti-Saccade Performance Predicts Executive Function And Brain Structure In Normal Elders, J. B. Mirsky, H. W. Heuer, A. Jafari, J. H. Kramer, A. K. Schenk, Indre Viskontas, B. L. Miller, A. L. Boxer

Psychology

Objective—To assess the neuropsychological and anatomical correlates of anti-saccade (AS) task performance in normal elders.

Background—The AS task correlates with neuropsychological measures of executive function and frontal lobe volume in neurological diseases, but has not been studied in a well-characterized normal elderly population. Because executive dysfunction can indicate an increased risk for cognitive decline in cognitively normal elders, we hypothesized that AS performance might be a sensitive test of age-related processes that impair cognition.

Method—The percentage of correct AS responses was evaluated in forty-eight normal elderly subjects and compared with neuropsychological test performance using linear regression analysis …

Multimodal Cuing Of Autobiographical Memory In Semantic Dementia, D. L. Greenberg, J. M. Ogar, Indre Viskontas, M. L. Gorno Tempini, B. Miller, B. J. Knowlton

Psychology

OBJECTIVE: Individuals with semantic dementia (SD) have impaired autobiographical memory (AM), but the extent of the impairment has been controversial. According to one report (Westmacott, Leach, Freedman, & Moscovitch, 2001), patient performance was better when visual cues were used instead of verbal cues; however, the visual cues used in that study (family photographs) provided more retrieval support than do the word cues that are typically used in AM studies. In the present study, we sought to disentangle the effects of retrieval support and cue modality.

METHOD: We cued AMs of 5 patients with SD and 5 controls with words, simple …

Learning From Mistakes: Improving Initial Fingertip Force Scaling By Observing Lifting Errors, Gavin Buckingham, Minnie Tang, Paul Gribble, Melvyn A. Goodale

Psychology Presentations

• When lifting objects that are lighter or heaver than we expect them to be, individuals typically misapply forces in a way that reflects their prior expectations of heaviness.

• Because we lift in this predictive way, large and small cubes elicit these characteristic errors even when they are adjusted to have equal mass. Lifters will apply too much force to a large cube and substantially less force to a small cube – errors that are rapidly corrected with repeated lifts (Flanagan & Beltzner, 2000).

• When watching others lift objects, an observer’s motor system automatically reacts in a way …

Neural Activity In The Hippocampus And Perirhinal Cortex During Encoding Is Associated With The Durability Of Episodic Memory, V. A. Carr, Indre Viskontas, S. A. Engel, B. J. Knowlton

Psychology

Studies examining medial temporal lobe (MTL) involvement in memory formation typically assess memory performance after a single, short delay. Thus, the relationship between MTL encoding activity and memory durability over time remains poorly characterized. To explore this relationship, we scanned participants using high-resolution functional imaging of the MTL as they encoded object pairs; using the remember/know paradigm, we then assessed memory performance for studied items both 10 min and 1 week later. Encoding trials were classified as either subsequently recollected across both delays, transiently recollected (i.e., recollected at 10 min but not after 1 week), consistently familiar, or consistently forgotten. …

Laterality, Perception, And Action During The Size-Weight Illusion, Gavin Buckingham, Nathalie S. Ranger, Melvyn A. Goodale

Psychology Presentations

In the classic size-weight illusion (SWI), a small object will feel heavier than an larger object of equal weight (Charpentier, 1891). Individuals continue to perceive this illusory difference in weight long after their gripping and lifting forces have scaled to the actual, identical, mass of the illusion-inducing stimuli (Flanagan & Beltzner, 2000).

The independence of our weight perception and fingertip force application has only been quantified in the right hand of right-handers. The immunity to this perceptual illusion may be affected by manual asymmetries (e.g., Gonzalez, Ganel & Goodale, 2006).

We examined perception of heaviness and fingertip force scaling in …

A Dissociation Between Perception And Action In The Material‐Weight Illusion, Gavin Buckingham, Jonathan S. Cant, Kai-Ling C. Kao, Melvyn A. Goodale

Psychology Presentations

We examined what forces are applied to objects that elicit this illusion when they are lifted.We predicted that:

(1) Forces on early trials will scale to each participant’s expectations of how much a particular block will weigh ‐ excessive force will be applied to the metal block and insufficient force applied to the polystyrene block.

(2) Forces on later trials will scale to the real weight of each block ‐ identical levels of force applied to all the blocks.

(3) MWI will persist throughout ‐ polystyrene block will feel the heaviest, metal block will feel the lightest.

Grasping And Lifting Different Materials, Gavin Buckingham, Jonathan S. Cant, Melvyn A. Goodale

Psychology Presentations

The material from which an object is made can determine how heavy it feels (Seashore, 1899). Interestingly, a metal block that has been adjusted to have the same size and mass as a polystyrene block will feel lighter than the polystyrene block. We recently showed that participants experiencing this material-weight illusion’ (MWI) do not apply forces that match their perceptual experience of heaviness ‐ just like in the size‐weight illusion ( Flanagan & Beltzner, 2000).

Our previous study showed that forces on early trials were scaled to each participant’s expectations of how much a particular block should weigh ‐ excessive …

Poetic Leadership, A Territory Of Aesthetic Consciousness And Change, R. Amrit Kasten-Daryanani

Antioch University Dissertations & Theses

Poetic leadership is a new theoretical construct that views leadership as an activity that unites a lyrical intellect with keenly felt emotion for the purpose of producing changes in the consciousness of self and others. This change begins within the interiority of self, moving surely to broader realms of one's surroundings and society, provoking movement that impacts the developing potential of the individual and the cultural milieu in which they exist. Emotion is the primary trace into consciousness used in this dissertation, which serves to unite experiences of the heart with experiences of the mind. The unification of these disparate …

Caring For People With Alzheimer's Disease Or Dementia In Maine, Stuart Bratesman Mpp, Julie T. Fralich Mba, Catherine Mcguire Bs, Louise Olsen, Romaine Turyn

Disability & Aging

It is clear that caring for people with Alzheimer’s disease and dementia is a growing public health issue. Alzheimer’s is a progressively deteriorating disease that can last anywhere from 1 to 15 years. Families are the primary caregivers and will continue to need support to manage the care of their loved ones, to coordinate services within the long term care system and to maintain their own health and well-being.

Contrasting Roles Of Neural Firing Rate And Local Field Potentials In Human Memory, A. Ekstrom, Indre Viskontas, M. Kahana, J. Jacobs, K. Upchurch, S. Bookheimer, I. Fried

Psychology

Recording the activity of neurons is a mainstay of animal memory research, while human recordings are generally limited to the activity of large ensembles of cells. The relationship between ensemble activity and neural firing rate during declarative memory processes, however, remains unclear. We recorded neurons and local field potentials (LFPs) simultaneously from the same sites in the human hippocampus and entorhinal cortex (ERC) in patients with implanted intracranial electrodes during a virtual taxi-driver task that also included a memory retrieval component. Neurons increased their firing rate in response to specific passengers or landmarks both during navigation and retrieval. Although we …

Differences In Mnemonic Processing By Neurons In The Human Hippocampus And Parahippocampal Regions, Indre Viskontas, B. J. Knowlton, P. N. Steinmetz, I. Fried

Psychology

Different structures within the medial-temporal lobe likely make distinct contributions to declarative memory. In particular, several current psychological and computational models of memory predict that the hippocampus and parahippocampal regions play different roles in the formation and retrieval of declarative memories [e.g., Norman, K. A., & O'Reilly, R. C. Modeling hippocampal and neocortical contributions to recognition memory: A complementary-learning systems approach. Psychological Review, 110, 611-646, 2003]. Here, we examined the neuronal firing patterns in these two regions during recognition memory. Recording directly from neurons in humans, we find that cells in both regions respond to novel stimuli with an increase …

Childhood Traumatic Brain Injury: Recovery Of Working Memory Function And Behavioral Adjustment, Gayle L. Crahen

All-Inclusive List of Electronic Theses and Dissertations

Children and adolescents with a traumatic brain injury (TBI) were the focus of this investigation using an extant data set. The 3 7 participants were between the ages of 5 and 15 years at the time of injury, and the majority had a severe TBI. Participants were evaluated soon after injury for a Baseline description of functioning on measures of cognition and memory and re-evaluated at one and/or two year return appointments. Parents provided estimates of adaptive, internalizing, and externalizing behaviors at Baseline and at follow-up appointments on the V ABS and CBCL. It was expected that parents' descriptions of …

Remote Episodic Memory Deficits In Patients With Unilateral Temporal Lobe Epilepsy And Excisions, Indre Viskontas, M. P. Mcandrews, M. Moscovitch

Psychology

The nature of remote memory impairment in patients with medial temporal lobe damage is the subject of some debate. While some investigators have found that retrograde amnesia in such patients is temporally graded, with relative sparing of remote memories (Squire and Alvarez, 1995), others contend that impairment is of very long duration and that remote memories are not necessarily spared (Sanders and Warrington, 1971; Nadel and Moscovitch, 1997). In this study, remote memory was assessed in 25 patients with unilateral temporal lobe epilepsy and 22 non-neurologically impaired controls using the Autobiographical Memory Interview (Kopelman et al., 1989). Results indicate that …
