A Laboratory-Based Experimental Test Of Reasons For Living: Effects On Behavioral Approach Toward A Suicide-Related Stimulus, Sasha Micaella Rojas

Graduate Theses and Dissertations

There are few laboratory-based experiments that examine the effects of suicide-related risk or protective factors on suicide-related outcomes. Consistent with extant evidence-based theoretical models and treatments for suicidal behavior, it appears that increasing awareness of reasons for living may reduce risk for suicidal behavior. Thus, the current study represents an initial effort to experimentally examine the impact of bringing awareness to one’s most important reason for living on behavioral approach towards a suicide-related stimulus. Random assignment was used to assign an unselected undergraduate sample of 78 participants to complete either a script-driven imagery procedure specific to the most important reason …

The Effect Of An Extinction Procedure On Level Of Responding To Visual Stimuli In An Evaluative Conditioning Procedure, Allison Hirsch

Dissertations, Theses, and Capstone Projects

Evaluative conditioning is a type of learning that results in the acquisition of likes and dislikes in humans. The procedure that produces evaluative learning is similar to that of Pavlovian conditioning. A consistent observation is that evaluative conditioned responses are less sensitive to extinction procedures than would be expected given the Pavlovian-type conditioning procedure used for acquisition. The present study sought to determine what the effect of an extinction condition was on the level of responding to visual conditioned stimuli in a visual-gustatory evaluative conditioning paradigm. Two dependent measures were used: an explicit measure, and a choice-based preference measure. The …

Delay Discounting And Cannabinoid Enzyme Inhibitors, Devin Andrew Galdieri

Graduate Theses, Dissertations, and Problem Reports (ETD)

Delay discounting is a measure of impulsive choice that is correlated with maladaptive behavior and psychological disorders. Disruptions to serotonin and dopamine pathways can cause changes in delay discounting, as can lesions to the prefrontal cortex and nucleus accumbens. The endocannabinoid system modulates other neurotransmitter systems, including dopamine and serotonin pathways. Cannabinoid receptors type 1 are found in relatively high concentrations in the nucleus accumbens and the prefrontal cortex. These receptors are activated by endogenous cannabinoids, which are synthesized on demand and broken down by catabolic enzymes. The action of these enzymes can be inhibited by a class of drugs …

Narcissistic Intolerance: Verbal Hostility And Dismissiveness In Response To Subjective Disagreement, Wan Wang

Theses and Dissertations (Comprehensive)

We examine the novel proposition that disagreement on matters of opinion may threaten narcissists’ self-esteem and cause them to express dismissiveness of differing opinions and hostility toward the dissenter, a phenomenon we refer to as narcissistic intolerance. In three studies, participants ostensibly read about an earlier participant’s opinion on a painting (Studies 1 & 2, MTurk samples) or TV show (Study 3, undergraduate sample) that agreed or disagreed with the participant’s own opinion. Participants then wrote a response to the opinion, as though they were responding on an anonymous Internet message board. We coded participants’ responses, finding that participants higher …

Radio Dispatch Cognitive Abilities And Working Memory, David A. Buitron

Electronic Theses, Projects, and Dissertations

Public safety radio dispatchers incontrovertibly have to manage multiple tasks at any given time, from relaying lifesaving information to field units, to simultaneously overseeing several monitors and keeping up with the radio transmissions in a timely manner. Interestingly, however, the underlying cognitive abilities necessitated for performing such tasks have not been thoroughly investigated. To begin understanding the cognitive faculties that underlie dispatching tasks, we gauged cognitive ability measures relevant to dispatcher duties and introduced Working Memory Capacity (WMC) as underlying the differentiation on performance. The four general dispatcher cognitive factors identified by Peace Officer Standards and Training (POST) literature, were …

Improving Planning: Quantitative Evaluation Of The Premortem Technique In Field And Laboratory Settings, Madeline Peabody

Dissertations, Master's Theses and Master's Reports

This thesis compares different plan evaluation techniques in a series of experiments. The Premortem plan evaluation method can help people reduce overconfidence and generate more reasons a plan might not succeed. This research evaluates the extension of the Premortem to shorter planning time periods, evaluates the effectiveness with team generated and executed plans, and compares the use of this technique among individuals and teams. In Experiment 1, 52 Army Cadets operating in teams completed six time-constrained field exercises that required planning, half using the Premortem and half using a standard Military plan evaluation process. When teams used the Premortem they …

Psychological Abuse, Mental Health, And Acceptance Of Dating Violence Among Adolescents, Jeff R. Temple, Hye Jeong Choi, Joanna Elmquist, Michael L. Hecht, Michelle Miller-Day, Gregory L. Stuart, Meagan Brem, Caitlin Wolford-Clevenger

Communication Faculty Articles and Research

Purpose

Existing literature indicates that acceptance of dating violence is a significant and robust risk factor for psychological dating abuse perpetration. Past work also indicates a significant relationship between psychological dating abuse perpetration and poor mental health. However, no known research has examined the relationship between acceptance of dating violence, perpetration of dating abuse, and mental health. In addition to exploring this complex relationship, the present study examines whether psychological abuse perpetration mediates the relationship between acceptance of dating violence and mental health (i.e., internalizing symptoms of depression, anxiety, and hostility).

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2^nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …

The Effect Of The Long Anchor Duration On Performance In The Temporal Bisection Procedure, Sho Araiba

Dissertations, Theses, and Capstone Projects

The present study investigated the determinants of the location of the bisection point (BP) in the temporal bisection procedure. Interest in the study of temporal perception emerged from the finding of the scalar property such as Weber’s law for time and the ratio rule in behavior under Pavlovian and instrumental conditioning. One method to investigate temporal perception in both non-human animals and humans is the temporal bisection procedure. The primary dependent variable of this procedure is the BP, which has been taken as the subjective midpoint between two durations. The ratio similarity rule (Gibbon, 1981) hypothesizes that the location of …

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …

The Relationship Between Adhd And Trait Facets Of The Five-Factor Model, Todd William Bennett

PCOM Psychology Dissertations

Facets of the Five-Factor Model (FFM) were examined in order to understand its interaction with Attention Deficit Hyperactivity Disorder (ADHD)-symptoms. By utilizing archival data, in a correlational design, adults between the ages of 18-66 were tested for the presence of ADHD, which was then compared with data gathered from the NEO-PI-R. Comorbid psychiatric conditions often associated with ADHD were accounted for in the design. Results partially supported the hypotheses, specifically, that altruism was inversely related to Impulsivity, as predicted. However, other findings largely did not support a relationship between other specific NEO-PI-R facets and ADHD. Other significant relationships that were …

Using The R-Pas' Aggressive Content Score For The Evaluation Of Aggressive Behaviors In Children, Rebecca Dehass

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

The Rorschach Performance Assessment System (R-PAS) was developed in 2011 as an alternative to the previous Comprehensive System. The goal was to improve the psychometrics, and particularly the validity, of this assessment method. The norms for children were questionable in the Comprehensive system (e.g., outdated, low numbers of subjects) and validity studies for children were sparse. One of the indicators included in the R-PAS system, the aggressive content indicator (AgC), is intended to reflect aggressive behavior, but few studies have examined the validity of this indicator. This study examined the validity of AgC in a sample of 32 children and …

Effects Of Societal Norm Manipulation And Presentation Order On Perceived Relationship Satisfaction, Tina Rene Negley

Electronic Theses and Dissertations

While many studies have examined the effects of persuasion on attitudes, few studies have focused on using norms to change perceived satisfaction. This study addressed the need for literature assessing the effects of societal norms on perceived relationship satisfaction. Participants in this study were randomly provided with one of two surveys: one with a set of normative statements regarding an "average couple" that were over-exaggerated, the other with understated norms. Analyses looked to identify whether individuals presented with the high norms were more likely to rate their relationship satisfaction lower, after controlling for demographic and personality characteristics. Hierarchical regression revealed …

Investigating The Roles Of Time Perspective And Emerging Adulthood In Predicting Driving Behavior, Kristie L. Johnson

Psychology Theses & Dissertations

In the U.S., motor vehicle crashes are the leading cause of death for individuals 2 to 34 years of age (National Highway Traffic Safety Administration, 2009c). Of particular interest are 18 to 25 year olds or emerging adults because of their increased crash risk. The prevalence of crashes attributable to the combination of driving inexperience and risky behaviors creates the necessity to identify predictors of crash likelihoods. While there are known personality variables that predict risky driving, time perspective as an additional one was suggested. Time perspective pertains to how the past, present, and future influence an individual's actions. Zimbardo, …

Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos

Dissertations

Alzheimer’s disease is a progressive neurodegenerative disease characterized by memory loss and cognitive decline. Although the symptomology of Alzheimer’s disease is well defined, its precise etiology remains elusive. Animal models are invaluable for understanding the pathogenesis of this devastating disease. Knowledge of the neurochemical actions of amyloid-β oligomers in specific brain structures is essential for validating animal models of Alzheimer’s disease and for determining the most appropriate behavioral assays of memory. The specific aim of this project was to investigate the neurochemical effects of direct intracerebral infusion of amyloid-β oligomers in the rat. Experiment 1 investigated direct infusions of synthetic …

Comparison Of Rationally-Derived And Empirically-Derived Methods For Predicting Failure In Residential Treatment, Jennifer Pester Grattan

Loma Linda University Electronic Theses, Dissertations & Projects

Patient-focused research methods have been used in adult mental health treatment to improve outcomes by tracking individual treatment response and comparing it with expected recovery patterns. One such approach has used rationally- and empirically-derived methods to analyze data from the OQ-45 and identify patients who are not responding as expected to treatment. Treatment is then adjusted, improving outcomes and lowering overall costs.

Similar but less extensive research has shown analogous methods can be used with children and adolescents. This would be particularly useful in residential treatment, which is an expensive and inadequately researched approach. This study used archival data gathered …

Accuracy Of A Rationally-Derived Method For Predicting Failure In Residential Treatment, Jennifer Pester Grattan

Loma Linda University Electronic Theses, Dissertations & Projects

Recent studies of adult mental health treatment have used patient-focused research methods to improve outcomes, by tracking treatment response and comparing it with expected recovery patterns. One such line of research has used rationally-derived and empirically-derived methods to analyze data gathered by the OQ-45 and identify patients who are not responding as expected to treatment. This allows for adjustment of treatment, which results in improved outcomes and lower overall costs.

Similar but less extensive research has provided evidence that these approaches may also improve outcomes in outpatient treatment for children and adolescents. These approaches might be particularly useful in residential …

Measuring Self-Disclosure Over The Internet, David Pope

Psychology Theses & Dissertations

A two-axial measure of disclosure intimacy by Morton (1976, 1978) was expanded to create a new measure usable for linear analyses. Morton's item of "Description" was divided into three "Context" items: Self-Concept, Interpersonal, and Taboo. The other axis of "Evaluation" was divided into four "Expression" items: Detail, Protected, Intensity, and Negativity/Vulnerability. As test data for the measure, demographic information from l50 users' weblogs was compared to free-response disclosures measured with the Morton measure and the linear Context/Expression measure. A multiple regression analysis of profile information versus disclosure intimacy did not reach significance. Results were inconclusive because the measures used in …

Affective Flexibility: Evaluative Processing Goals Shape Amygdala Activity, William A. Cunningham, Jay J. Van Bavel, Ingrid Johnsen Haas

Department of Political Science: Faculty Publications

Although early research implicated the amygdala in automatic processing of negative information, more recent research suggests that it plays a more general role in processing the motivational relevance of various stimuli, suggesting that the relation between valence and amygdala activation may depend on contextual goals. This study provides experimental evidence that the relation between valence and amygdala activity is dynamically modulated by evaluative goals. During functional magnetic resonance imaging, participants evaluated the positive, negative, or overall (positive plus negative) aspects of famous people. When participants were providing overall evaluations, both positive and negative names were associated with amygdala activation. When …

Using Latent Semantic Analysis To Assess Reader Strategies, Joseph P. Magliano, Katja Wiemer-Hastings, Keith K. Millis, Brenton D.. Muñoz, Danielle Ncnamara

Psychology Faculty Publications

We tested a computer-based procedure for assessing reader strategies that was based on verbal protocols that utilized latent semantic analysis (LSA). Students were given self-explanation-reading training (SERT), which teaches strategies that facilitate self-explanation during reading, such as elaboration based on world knowledge and bridging between text sentences. During a computerized version of SERT practice, students read texts and typed self-explanations into a computer after each sentence. The use of SERT strategies during this practice was assessed by determining the extent to which students used the information in the current sentence versus the prior text or world knowledge in their self-explanations. …
