Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

Uncovering The Neural And Behavioral Factors That Underlie Changes In Processing Visual Orientation, Patrick Sadil

Doctoral Dissertations

From moment to moment, the visual environment appears stable; despite prolonged scrutiny, the edge of a desk is not perceived to change. But this apparent stability emerges from perceptual and decisional systems that undergo continuous modulation. In two chapters, I focus on two different kinds of modulation to the processing of visual orientation (i.e., the tilt of an edge). In both chapters, the form of modulation is latent, obscured by standard analyses. To detect those latent changes in perceptual decisions, I develop in this dissertation new statistical tools, at both behavioral and neural levels. In the first chapter, I consider …

Effects Of Alcohol Intoxication On Hostile Attribution Bias And Relational Aggression In Women, Alita M. Mobley

Graduate Theses and Dissertations

Alcohol intoxication is consistently linked to physical and sexual aggression in men, but not women. The lack of evidence supporting the relationship between alcohol and aggression for women could be due to a failure to measure relational aggression (i.e., harmful social manipulation), the form of aggression more commonly employed by women. Further, alcohol intoxication may interfere with the interpretation of social cues, resulting in greater perceived provocation in ambiguous social interactions and increased aggression. The current study examined the relationship between alcohol intoxication and relational aggression in women and the extent to which interpretation of social cues (i.e., hostile attribution …

Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders

Undergraduate Research Symposium

Abstract

Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …

Establishing Auditory Discrimination And Echoic Stimulus Control With An Auditory Matching Procedure, Clare Christe

Dissertations

A generalized auditory matching repertoire is considered an early milestone in the development of verbal behavior (Greer & Keohane, 2006). Previous literature has demonstrated that the auditory matching (AM) protocol can improve echoics in individuals with developmental delays (Brown, 2005; Choi, Greer & Keohane, 2015; Du, Speckman, Medina, & Cole-Hatchard, 2017). However, some children experience difficulties with the match-to-sample (MTS) format of the AM protocol, if they are unable to perform delayed MTS tasks.

One alternative to MTS is the go/no-go procedure (Serna, Dube, & McIlvane, 1997), which requires the student to make a simple discrimination (i.e., same/different) between two …

Previous Experiences Drive Attention, Sunghyun Kim

LSU Doctoral Dissertations

Traditionally, the allocation of attention was understood within goal-driven and stimulus-driven factors. However, the traditional approach cannot fully account for the mechanism of attentional orienting. Instead, a growing body of evidence shows that previous search experiences, irrelevant to both goal-driven and stimulus-driven factors, influence attentional allocation. For example, when contexts predict information of targets, the contexts guide attention toward the stimuli having the information predicted by the contexts: contextual cueing. In addition, more valuable stimuli attract more attention: value-driven attentional capture. However, two critical issues are present. First, contextual cueing has been found largely when the contexts and the target …

A Novel Approach To Studying Human Intelligence-Gathering: Employing A Realistic Paradigm For The Study Of Elicitation Approaches, Sarah A. Shaffer

FIU Electronic Theses and Dissertations

It is often necessary to interrogate sources of information when threats to national security (e.g., impending terror attack) are present. However, the overwhelming majority of research focuses on the interrogation of criminal suspects despite the arguably greater consequences of the former context, known as Human Intelligence (HUMINT) collection. The present study is the first to examine a highly successful approach to collecting information from sources of human intelligence (HUMINT)- the Scharff Technique.- within a novel and highly realistic paradigm. Participants were recruited for a study on group interaction. Every group contained a study confederate posing as a participant who gave …

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

Theses and Dissertations

Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.

Increasing The Echoic Repertoire Of A Child With Autism Using An Imitation And Echoic Sequence, Rose Bridges

Honors Theses

A prerequisite to many things in life is the ability to communicate. Although this may mean many different things, such as verbal language, sign language, written language, and even icons, there must be some form of communication that may be utilized to get needs across. Many young children with autism spectrum disorder (ASD) are non-verbal, however there are also many children with ASD who have the ability to say words but are still not independently speaking. Reinforcing approximations to word sounds has been previously used as an effective way of increasing the child’s verbal repertoire (Shane, 2017). The present study …

The Effects Of Interruption Relevance And Complexity On Primary Task Resumption And Mental Demand, Brandon Allan Fluegel

Psychology Theses & Dissertations

In the present study, undergraduate students viewed patient charts and entered numerical values from these charts into a medical record database. They were unexpectedly interrupted by secondary tasks that differed in relevance and complexity. The secondary tasks varied by whether they facilitated or inhibited (i.e., relevant or irrelevant) rehearsal of the suspended task and whether they placed a demand on working memory (i.e., high complexity or low complexity). The primary measures of interest were the duration of time needed to resume the primary task and perceived mental demand. The Memory for Goals model (Altmann & Trafton, 2002) predicts that task …

Testing The Convergent Retrieval Learning Theory Of Testing Effects, William J. Hopper

Doctoral Dissertations

What is learned from retrieving a memory that is not learned by studying the same information? In response to this question, I have proposed a new theory of retrieval-based learning in which I argue that retrieval strengthens the ability to completely activate all portions of a memory trace from an initial state of partial activation. In effect, retrieval serves to unitize the features of a memory, making the entire memory remain retrievable in the future when cue-related activation may be weaker. This theory, called the Primary and Convergent Retrieval (PCR) model, explains why practice tests produce both better long-term retention …

The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran

Theses and Dissertations--Psychology

During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …
