The Electrophysiological And Neuropsychological Organization Of Long Term Memory, Richard J. Addante

Psychology Faculty Publications

The electrophysiological correlates of recognition memory retrieval were examined in order to identify the neural conditions that precede accurate memory retrieval, characterize the processes that contribute to high and low confidence memory responses, and determine which memory processes are impaired after brain injury. Human electroencephalogram (EEG) was recorded during recognition confidence and source memory judgments in three experiments. In Experiment 1, mid-frontal pre-stimulus theta oscillations were found to precede the stimulus presentation of items that were successfully recollected, but they were not found to be predictive of item familiarity. Moreover, during stimulus presentation, recollection was associated with an increase in …

Age Differences In Revision Of Causal Belief, Kristi M. Simmons

Masters Theses & Specialist Projects

Inductive reasoning (IR) requires efficient working memory (WM). Research shows that the prefrontal cortex (PFC) is involved during WM tasks and that PFC functioning declines with age. The ability to comprehend and update text-based information requires an intact PFC and efficient WM and IR. The current study presented a series of messages about the investigation of a warehouse fire to 48 young and 48 older adults. One message contained a piece of misinformation which another message corrected later. It was hypothesized that a memory cue to the misinformation with the correction statement should benefit older adults the most during the …

Perceptions Of Sexual Dangerousness: Accurate Identification Of Sexual Offenders From Static Photographs, Amber Jean Culbertson-Faegre

Graduate Theses and Dissertations

The present research expands understanding of the phenomenon of accurate identification of sexually dangerous men. Study 1 was designed to examine the influence of experience on accuracy of perceptions of sexual dangerousness. Receiving feedback about test trials increased accuracy on future trials at a marginally significant level. Study 2 was designed to determine the importance of specific facial features on these judgments. This study, however, failed to replicate the findings from the first study. Implications for Study 1, as well as possible explanations for Study 2 are discussed.

From Nixon’S War On Drugs To Obama’S Drug Policies Today: Presidential Progress In Addressing Racial Injustices And Disparities, Cigdem V. Sirin

Cigdem V. Sirin

This study investigates presidential progress in addressing racial injustices and disparities within the context of the war on drugs. I argue that racial inequalities emanating from the war on drugs have been largely overlooked and at times aggravated by previous administrations. Although there have been some improvements in this regard since President Obama took office, more extensive policy reforms are needed to better remedy such inequalities. I also argue that the viability of a progressive presidency for racial justice vis-à-vis U.S. drug policies depends not only on the personal agenda of the president but also on a supportive public as …

The Impact Of Category Separation On Unsupervised Categorization, Shawn W. Ell, Gregoryh F. Ashby

Psychology Faculty Scholarship

Most previous research on unsupervised categorization has used unconstrained tasks in which no instructions are provided about the underlying category structure or the stimuli are not clustered into categories. Few studies have investigated constrained tasks in which the goal is to learn pre-defined stimulus clusters in the absence of feedback. These studies have generally reported good performance when the stimulus clusters could be separated by a one-dimensional rule. The present study investigated the limits of this ability. Results suggest that even when two stimulus clusters are as widely separated as in previous studies, performance is poor if within-category variance on …

Pathological Personality Traits Among Patients With Absent, Current, And Remitted Substance Use Disorders, Christopher J. Hopwood, Leslie C. Morey, Andrew E. Skodol, Charles A. Sanislow, Carlos M. Grilo, Emily B. Ansell, Thomas H. Mcglashan, John C. Markowitz, Anthony Pinto, Shirley Yen, M. Tracie Shea, John G. Gunderson, Mary C. Zanarini, Robert L. Stout

Charles A. Sanislow, Ph.D.

Personality traits may provide underlying risk factors for and/or sequelae to substance use disorders (SUDs). In this study Schedule for Nonadaptive and Adaptive Personality (SNAP) traits were compared in a clinical sample (N=704, age 18–45) with current, past, or no historical alcohol or non-alcohol substance use disorders (AUD and NASUD) as assessed by DSM-IV semi-structured interview. Results corroborated previous research in showing associations of negative temperament and disinhibition to SUD, highlighting the importance of these traits for indicating substance use proclivity or the chronic effects of substance use. Certain traits (manipulativeness, self-harm, disinhibition, and impulsivity for AUD, and disinhibition and …

The Effects Of Caffeine And Expectancy On Short Term Memory, Sara O'Brien

Doctoral Dissertations and Master's Theses

Although caffeine is the most widely used drug in the world, research on the effects of caffeine on mental performance tasks (especially short term memory tasks) is inconclusive. One possible explanation for this limited understanding is the lack of studies accounting for participant expectancy surrounding caffeine. This study examined the effects of caffeine dosage (0mg, 200mg, and 400mg) and expectancy related to past caffeine use (positive, negative) on short term memory span task. A two-way Analysis of Variance showed that the two independent variables (caffeine dose and expectancy), did not significantly influence the short term memory span score. However, the …

Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge

Faculty Journal Articles

Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second …

Selective Attention For Masked And Unmasked Threatening Words In Anxiety: Effects Of Trait Anxiety, State Anxiety And Awareness, Mark Edwards, Jennifer S. Burt, Ottmar V. Lipp

Mark Edwards

We investigated the effects of awareness on selective attention for masked and unmasked verbal threat material using a computerised version of the emotional Stroop. Participants were assigned to the high trait anxious (HTA) and low trait anxious (LTA) groups on the basis of questionnaire scores, and state anxiety was manipulated within participants through the threat of electric shock. To investigate the effects of awareness on responses to threat, the mode of exposure was blocked such that half the participants received masked trials before the unmasked trials, whereas the other half received the reverse order. The results revealed that there was …

A Kinder, Gentler Nativism?: Review Of Alison Gopnik, The Philosophical Baby, David Moshman

Department of Educational Psychology: Faculty Publications

Review of Alison Gopnik, The philosophical baby: What children's minds tell us about truth, love, and the meaning of life.

In its historic philosophical and psychological formulations, nativism highlighted innateness. Development was deemed nothingmore than a genetically driven process ofmaturation; learning, in turn, was nothing more than the filling in of superficial content. In this determinist view, neither development nor learning could be deemed active, creative, or constructive processes, and nothing genuinely new could result.

The nativists who have increasingly populated the literature of developmental psychology since the 1980s, however, are neonativists. Neonativists fully accept modern views of immature organisms …

Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …

Examining The Effects Of Political Information And Intervention Stages On Public Support For Military Interventions: A Panel Experiment, Cigdem V. Sirin

Cigdem V. Sirin

This study examines the formation and continuity of public support for military interventions as a function of political information levels and intervention stages using a panel experiment. The results demonstrate that politically informed individuals express less support for a military intervention at the beginning of that intervention compared to uninformed ones. However, as the intervention proceeds and casualties are incurred, the support of politically uninformed people decreases at a higher rate than does the support of the politically informed. As such, politically informed individuals demonstrate more stable levels of support across intervention stages. In addition, success or failure of an …

Thinking Like Thinkers: Is The Art And Discipline Of An "Attitude Of Suspended Conclusion" Lost On Lawyers?, Donald J. Kochan

Donald J. Kochan

In his 1910 book, How We Think, John Dewey proclaimed that “the most important factor in the training of good mental habits consists in acquainting the attitude of suspended conclusion. . .” This Article explores that insight and describes its meaning and significance in the enterprise of thinking generally and its importance in law school education specifically. It posits that the law would be best served if lawyers think like thinkers and adopt an attitude of suspended conclusion in their problem solving affairs. Only when conclusion is suspended is there space for the exploration of the subject at hand. The …

Intact Statistical Word Learning In Autism Spectrum Disorders, Jessica Mayo

Master's Theses

Individuals with Autism Spectrum Disorders (ASD) have impairments in language acquisition, but the underlying mechanism of these deficits is poorly understood. Implicit learning appears potentially relevant to language development, particularly in speech segmentation, which relies on sensitivity to the transitional probabilities between speech sounds. This study aimed to investigate the relationship between implicit learning and current language abilities in school-aged children with autism (n = 17) and typical development (n = 24) using a well-studied artificial language learning task. Results suggest that the ASD and TD groups were equally able to implicitly learn transitional probabilities from a lengthy …
