"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 …


Dynamics Of Alpha Control: Preparatory Suppression Of Posterior Alpha Oscillations By Frontal Modulators Revealed With Combined Eeg And Event-Related Optical Signal, Kyle E. Mathewson, Diane M. Beck, Tony Ro, Edward L. Maclin, Kathy A. Low, Monica Fabiani, Gabriele Gratton Oct 2014

Dynamics Of Alpha Control: Preparatory Suppression Of Posterior Alpha Oscillations By Frontal Modulators Revealed With Combined Eeg And Event-Related Optical Signal, Kyle E. Mathewson, Diane M. Beck, Tony Ro, Edward L. Maclin, Kathy A. Low, Monica Fabiani, Gabriele Gratton

Publications and Research

We investigated the dynamics of brain processes facilitating conscious experience of external stimuli. Previously, we proposed that alpha (8–12 Hz) oscillations, which fluctuate with both sustained and directed attention, represent a pulsed inhibition of ongoing sensory brain activity. Here we tested the prediction that inhibitory alpha oscillations in visual cortex are modulated by top–down signals from frontoparietal attention networks. We measured modulations in phase-coherent alpha oscillations from superficial frontal, parietal, and occipital cortices using the event-related optical signal (EROS), a measure of neuronal activity affording high spatiotemporal resolution, along with concurrently recorded EEG, while participants performed a visual target detection …


When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn Oct 2014

When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …


“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz Sep 2014

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …


The Antisaccade Task: Visual Distractors Elicit A Location-Independent Planning 'Cost', Jesse C. Desimone Aug 2014

The Antisaccade Task: Visual Distractors Elicit A Location-Independent Planning 'Cost', Jesse C. Desimone

Electronic Thesis and Dissertation Repository

Prosaccades are rapid eye movements with direct stimulus and response relations and are designed to bring the fovea onto a target or area of interest. In contrast, antisaccades require the inhibition of a prosaccade and the evocation of a saccade to a target’s mirror-symmetrical location. Previous work has shown that a remote (i.e., midline, contralateral) – but not proximal (i.e., ipsilateral) – task-irrelevant distractor relative to a visual target delays prosaccade reaction times (RT) (i.e., remote distractor effect: RDE). To my knowledge, however, no work has examined whether antisaccade RTs are similarly influenced by a RDE. Accordingly, I sought to …


Impaired Theory Of Mind In Psychotic And Affective Disorders, Erik Nelson Ringdahl Aug 2014

Impaired Theory Of Mind In Psychotic And Affective Disorders, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychotic symptoms in bipolar I disorder during mood episodes has been associated with several negative outcomes raising the question as to whether psychosis is a risk factor for a more severe form of this chronic and debilitating condition. However, relatively little research has been directed at understanding the relationships among social cognitive functioning in bipolar I disorder with and without a history of psychosis. Impaired social cognition has been identified as a putative endophenotypic markers in schizophrenia and the evidence is mounting as to whether similar impairments also exist in bipolar I disorder. Given the plethora of research supporting the …


Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston Jul 2014

Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston

Open Access Theses

Compensation for coarticulation is the extent in which an individual perceives the contextual variations of speech. When presented with an ambiguous consonant-vowel segment (e.g., a consonant halfway between /sa/ and /∫a/) research illustrates that a listener is likely to compensate for coarticulation with the following vowel. Therefore, a listener will be more likely to report an ambiguous speech sound as /s/ when it occurs before [u] than before [a]. Previous results have suggested that, within neurotypical individuals, the degree to which individuals compensate for coarticulation may be related to their Autism Quotient (AQ; Yu, 2010). However, this research did not …


Mindfulness At Work: Antecedents And Consequences Of Employee Awareness And Absent-Mindedness, Jochen Reb, Jayanth Narayanan, Zhi Wei Ho Jun 2014

Mindfulness At Work: Antecedents And Consequences Of Employee Awareness And Absent-Mindedness, Jochen Reb, Jayanth Narayanan, Zhi Wei Ho

Jochen Reb

The present study examines antecedents and consequences of two aspects of mindfulness in a work setting: employee awareness and employee absent-mindedness. Using two samples, the study found these two aspects of mindfulness to be beneficially associated with employee well-being, as measured by emotional exhaustion, job satisfaction, and psychological need satisfaction, and with job performance, as measured by task performance, organizational citizenship behaviors, and deviance. These results suggest a potentially important role of mindfulness at the workplace. The study also found that organizational constraints and organizational support predicted employee mindfulness, pointing to the important role that the organizational environment may play …


The Influence Of Mindful Attention On Value Claiming In Distributive Negotiations: Evidence From Four Laboratory Experiments, Jochen Reb, Jayanth Narayanan Jun 2014

The Influence Of Mindful Attention On Value Claiming In Distributive Negotiations: Evidence From Four Laboratory Experiments, Jochen Reb, Jayanth Narayanan

Jochen Reb

We examined the effect of mindful attention on negotiation outcomes in distributive negotiations across four experiments. In Studies 1 and 2, participants who performed a short mindful attention exercise prior to the negotiation claimed a larger share of the bargaining zone than the control condition participants they negotiated with. Study 3 replicated this finding using a different manipulation of mindful attention. Study 4 again replicated this result and also found that mindful negotiators were more satisfied with both the outcome and the process of the negotiation. We discuss theoretical and practical implications, limitations, and future directions.


Do Culture And Biological Sex Influence People Who Engage In Non-Suicidal Self-Injury?, Rachel Berger May 2014

Do Culture And Biological Sex Influence People Who Engage In Non-Suicidal Self-Injury?, Rachel Berger

Graduate Theses

Non-Suicidal Self-Injury (NSSI) refers to behaviors in which a person intentionally harms and causes tissue damage to oneself, without the desire to end his or her life. There have been contradictory findings with regard to differences in NSSI by biological sex and culture. In this study, I sought to examine if adults with independent cultural self- construals would report more occurrences of NSSI in comparison to those with interdependent cultural self-construals. Furthermore, I was interested in whether females would report more instances of NSSI in comparison to males in independent based cultures, and I examined whether the methods and reasons …


Direct Control Of Visual Perception With Phase-Specific Modulation Of Posterior Parietal Cortex, Andrew Jaegle, Tony Ro Feb 2014

Direct Control Of Visual Perception With Phase-Specific Modulation Of Posterior Parietal Cortex, Andrew Jaegle, Tony Ro

Publications and Research

We examined the causal relationship between the phase of alpha oscillations (9–12 Hz) and conscious visual perception using rhythmic TMS (rTMS) while simultaneously recording EEG activity. rTMS of posterior parietal cortex at an alpha frequency (10 Hz), but not occipital or sham rTMS, both entrained the phase of subsequent alpha oscillatory activity and produced a phase-dependent change on subsequent visual perception, with lower discrimination accuracy for targets presented at one phase of the alpha oscillatory waveform than for targets presented at the opposite phase. By extrinsically manipulating the phase of alpha before stimulus presentation, we provide direct evidence that the …


Longitudinal Change In Regional Cortices And Fluid Intelligence, Peng Yuan Jan 2014

Longitudinal Change In Regional Cortices And Fluid Intelligence, Peng Yuan

Wayne State University Dissertations

Fluid intelligence (Gf) and crystalized intelligence (Gc) are two factors of the general intelligence. They have distinct age-related trajectories of change. Jung and Haier proposed Parieto-Frontal Integration Theory (P-FIT, 2007) to account for the inter-person variance in reasoning intelligence. Some brain regions such as prefrontal, parietal, temporal and anterior cingulate cortices were included in the P-FIT model and were hypothesized to be involved in fluid reasoning task. Therefore, in the current study, we examined latent growth curves (LGC) of longitudinal change in Gf, Gc, prefrontal cortex, parietal cortex, anterior cingulate, temporal cortex and primary visual cortex. Forty-six healthy middle-aged and …


Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies, Ana Marie Daugherty Jan 2014

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 …


Commentary: Reflections On Remorse, Stephen J. Morse Jan 2014

Commentary: Reflections On Remorse, Stephen J. Morse

All Faculty Scholarship

This commentary on Zhong et al. begins by addressing the definition of remorse. It then primarily focuses on the relation between remorse and various justifications for punishment commonly accepted in Anglo-American jurisprudence and suggests that remorse cannot be used in a principled way in sentencing. It examines whether forensic psychiatrists have special expertise in evaluating remorse and concludes that they do not. The final section is a pessimistic meditation on sentencing disparities, which is a striking finding of Zhong et al.
