Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh Dec 2020

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.


Application Of The “Idisco” Full-Brain Tissue Clearing Method: A View Of Dopamine And Inflammation In The Hiv-1 Transgenic Rat, Kristin Nickole Kirchner Oct 2020

Application Of The “Idisco” Full-Brain Tissue Clearing Method: A View Of Dopamine And Inflammation In The Hiv-1 Transgenic Rat, Kristin Nickole Kirchner

Theses and Dissertations

The iDISCO (immunolabeling-enabled three-dimensional imaging of solvent-cleared organs) method is a quick, inexpensive, and easily adaptable tissue staining and clearing procedure that allows neuroscientists to study a protein of interest in a whole, unaltered tissue sample. While the iDISCO method was initially tested and validated for mice embryos and brains, the current experiment sought to adapt the method for use in the rat using HIV-1 transgenic (Tg) rat brain tissue. Antibodies for tyrosine hydroxylase and Iba-1 were validated in the HIV-1 Tg rat and in F344/N control rats using iDISCO. Confocal images were taken of tyrosine hydroxylase positive neurons in …


The Behavioral And Neural Effects Of Audiovisual Affective Processing, Chuanji Gao Jul 2020

The Behavioral And Neural Effects Of Audiovisual Affective Processing, Chuanji Gao

Theses and Dissertations

In everyday life, we receive affective information from a multisensory environment. What we see and what we hear jointly influence how we feel, think and act. Outstanding questions still remain about the essential behavioral and neural mechanism underlying how we combine visual and auditory affective signals. In this dissertation, I report a series of behavioral, EEG and fMRI experiments addressing this question. I found behaviorally there are congruency, visual dominance, and negativity dominance effects. Using ERPs, I showed that these behavioral effects can map onto different time course in audiovisual affective processing. Time-frequency analyses of EEG data showed that there …


Testing For Differential Attention To Features In Evaluative Conditioning, Christine E. Weber Jul 2020

Testing For Differential Attention To Features In Evaluative Conditioning, Christine E. Weber

Theses and Dissertations

One eye tracking and one behavioral experiment examined the possible roles of contingency awareness and attention to stimulus features in evaluative conditioning. These experiments tested whether evaluative conditioning altered the saliency of positive and negative features in consumer products (Study 1) and attitudinal responses to ambivalent pictures (Study 2). Based on the conceptual categorization model, pairing of ambivalent conditioned stimuli with liked or disliked unconditioned stimuli was predicted to result in enhanced attention to affectively congruent features. Study 1 tested this prediction by recording eye movements to determine how attention to features and responses to ambivalent stimuli were altered as …


Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola May 2020

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.


The Maze Of Personality: Latency And Electric Organ Discharge In A Mormyrid Fish, Gnathonemus Petersii Gunther 1862 (Mormyridae, Teleostei), Abbey C. Lipe May 2020

The Maze Of Personality: Latency And Electric Organ Discharge In A Mormyrid Fish, Gnathonemus Petersii Gunther 1862 (Mormyridae, Teleostei), Abbey C. Lipe

Theses and Dissertations

Personality is individual differences in behavior, consistent across contexts. Among Gnathonemus petersii we investigated, we hypothesized that fish could be grouped by: (1) slow/fast maze performance, (2) low/high electric frequencies, (3) correlated latency and frequency. Our first two hypothesis were not supported. Our third hypothesis was partially supported.
