The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig
The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig
Dissertations, Theses, and Capstone Projects
Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …
Competitive And Facilitative Interactions Between Pavlovian Cues In Human Associative Learning: A Behavioral And Neural Analysis, Fahd Alhazmi
Dissertations, Theses, and Capstone Projects
Learning to anticipate significant events accurately is a crucial element of survival for all species. The process by which animals acquire this knowledge has been a central question of psychological research. A fundamental assumption of many learning theories is that the predictive value assigned to cues is not simply determined by their probability of reinforcement but rather by their ability to compete with other cues present during learning. The assumption of cue competition has significantly contributed to the development of behavioral and neuroscience research for decades, as it has opened the door to new empirical and theoretical advances on the …
Neuroanatomy In Mild Cognitive Impairment: Relationship To Functional Skills, Treatment Expectancy, And Comorbid Depression, Sara Rushia
Dissertations, Theses, and Capstone Projects
Mild cognitive impairment (MCI) is a neurocognitive disorder defined by cognitive decline in older adults. Although MCI has been studied for decades, there remain important areas to be explored in order to adequately characterize aspects of this disorder that provide information valuable for possible interventions and disease progression to dementia, including a better understanding of the neuroanatomical variables relevant to this disorder. Such neuroanatomical variables include cortical thickness, hippocampal volume, and white matter hyperintensities (WMHs). This dissertation consists of three separate studies aimed at addressing gaps in the literature on MCI in relation to brain morphometrics and under-studied characteristics involved …
Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell
Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell
Dissertations, Theses, and Capstone Projects
Successful regulation of fear memories is a fundamental tenet to the exposure-based therapies often employed by mental health professionals for individuals with PTSD, phobias, and other anxiety disorders. Consequently, the efficacy of these treatment methodologies is largely dependent on the strength of the fear memory, as stronger memories are often characterized by an increased resistance to extinction and heightened fear recovery. However, there is little consensus within the scientific community regarding how to effectively maximize fear memory strength in human studies, and the literature exploring the impact of variability in acquisition parameters on memory strength is sparse. Here, we tested …
Adapting Small Unmanned Aerial Systems For Behavioral Research With Coastal Marine Mammals, Eric Angel Ramos
Adapting Small Unmanned Aerial Systems For Behavioral Research With Coastal Marine Mammals, Eric Angel Ramos
Dissertations, Theses, and Capstone Projects
Marine mammals inhabit aquatic worlds where their subsurface behavior, cryptic surface profiles, and movements make them difficult to study. New tools are needed to study coastal marine mammals in a world increasing impacted by climate change related shifts in weather and animal distribution patterns. Unmanned aerial systems (UAS) are important remote-sensing tools for studying a range of wildlife including terrestrial and aquatic flora and fauna. These systems offer flexible platforms for adding sensor packages needed for different applications, for example, most are equipped with high-resolution cameras and GPS sensors. The vantage point from an aerial platform dramatically improves the ability …
