Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh
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.
Wrongful Conviction Documentaries: Influences Of Crime Media Exposure On Mock Juror Decision-Making, Patricia Y. Sanchez
Wrongful Conviction Documentaries: Influences Of Crime Media Exposure On Mock Juror Decision-Making, Patricia Y. Sanchez
Dissertations, Theses, and Capstone Projects
Psychology and law researchers have urged colleagues to collaborate with the makers of popular media, such as documentary filmmakers, in efforts to educate the general public about wrongful convictions (Kassin, 2017; Wells et al., 2000). Recently, programs depicting wrongful convictions, such as Making a Murderer (Demos & Ricciardi, 2015) and When They See Us (DuVernay, 2019) have garnered substantial viewership. Research on general and case-specific pretrial publicity (Daftary-Kapur et al., 2014; Kovera, 2002) and the effects of crime media (Baskin & Sommers, 2010; Schweitzer & Saks, 2007) demonstrate that although consuming crime-related media and being exposed to information about a …
Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola
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
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.
Experience-Dependent Changes In Nucleus Accumbens Activity Predict Cued Approach Learning: Contribution Of Nmda Receptors, Mercedes Vega Villar
Experience-Dependent Changes In Nucleus Accumbens Activity Predict Cued Approach Learning: Contribution Of Nmda Receptors, Mercedes Vega Villar
Dissertations, Theses, and Capstone Projects
Animals learn associations between environmental cues and the natural rewards they predict (e.g., food, water, sex). As a result, reward-predictive cues come to trigger vigorous reward-seeking responses. Many neurons in the nucleus accumbens (NAc) become excited upon presentation of an already-learned reward-predictive cue. These NAc responses encode the motivational value of the cue and are necessary for the expression of the subsequent approach behavior. However, the precise temporal relationship between the emergence of cue-evoked excitations in the NAc and the acquisition of cued approach behavior remains unknown. In Experiment 1, NAc activity was recorded as rats learned to approach a …
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref
Dissertations and Theses
In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …
