Components Of Mindfulness Training: Impacts On Attention And Affect, Maximilian Fey
Components Of Mindfulness Training: Impacts On Attention And Affect, Maximilian Fey
Graduate Theses and Dissertations
The literature on mindfulness supports a distinction between two components of non-judgmental acceptance and directed attention. The present research analyzed whether there are distinct differences in attentional capabilities or affect between mindfulness inductions which differed in either including only directed attention or directed attention and non-judgmental acceptance. I hypothesized that the acceptance component of mindfulness would increase participants sustained attentional capabilities relative to a control condition; furthermore, I hypothesized that the non-judgmental acceptance component of mindfulness would lead to significant increases in positive affect and decreases in negative affect relative to control. Lastly, I hypothesized that an individual difference measure …
The Feedback-Related Negativity Is A Time-Dependent Brain Mechanism That Facilitates Aversive Learning: Implications For The Reinforcement Learning Frn Hypothesis, Eric Rawls
Graduate Theses and Dissertations
Organisms encode rewarding and aversive experiences through reinforcement learning, capitalizing on prediction errors (PEs), which adapt action strategies over time. Computational theories are explicit that PE signals should update action weights continuously over the course of a behavioral task, an important time-dependent variation that is eschewed in traditional neuroscience studies that average over large numbers of trials. I examined variation in reaction times and feedback-locked cortical activity over time as a function of PE to critically examine theories indicating that PE signals drive time-dependent learning. We recorded EEG while participants completed a novel reinforcement task that varied prediction error on …
Implicit Bias And The Boundaries Of Belief: A Single-Representational Dual-Attitude Account Of Implicit Attitudes, Austin Dakota Synoground
Implicit Bias And The Boundaries Of Belief: A Single-Representational Dual-Attitude Account Of Implicit Attitudes, Austin Dakota Synoground
Graduate Theses and Dissertations
Since their inception, implicit attitudes have been defined as associative mental states, separate from beliefs, which are considered to be propositional in nature. Recently, several philosophers have challenged this distinction, arguing that implicit attitudes are actually unconscious beliefs. In turn, I argue that the attitudes detected by current experimental paradigms are blind to distinctions between implicit attitudes, which I define as the products of an associative learning mechanism, and unconscious beliefs, which are the products of a propositional learning mechanism. Specifically, I argue for a single-representational dual-attitude account of implicit bias.
Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race
Like Me, Do What I Say, & Think About My Influence: The Effects On Witness Choosing And Metacognition, Brittany Race
Graduate Theses and Dissertations
Confidence can be a strong predictor of accuracy if circumstances are ideal (Wixted & Wells, 2017), but ideal circumstances are not always present. As such it is important to understand ways to ameliorate potentially negative effects on eyewitness metacognition. Rapport building, though seen as an important element of police/witness interaction (Vallano et al., 2015), can lead to some potentially negative memory effects (Wright et al., 2015). Additionally steering, or the process of directing a witness toward a particular suspect, can increase false identifications. Recently the researcher has developed a paradigm meant to better calibrate confidence by reinstating the context of …
How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian
How Does Alcohol Intoxication Impair Risk Detection Of Sexual Assault? Testing An Integration Of Alcohol Myopia And Social Information Processing Theories, Alexander James Melkonian
Graduate Theses and Dissertations
Sexual assault among young adults is a highly prevalent public health concern. Alcohol is often implicated as a risk factor for sexual assault through its impairing effects on an individual’s ability to process and respond to social cues in the environment. The effect of alcohol myopia can result in greater focus of attention on salient environmental cues. The relationship between alcohol intoxication and resulting behavior may depend on what type of information is most salient. The current study examined the effects of alcohol on social information processing as it relates to sexual assault risk detection. Method: Participants were 48 young …
Effects Of Critical Reflection On University Students’ Cognitive Achievement In Agricultural Mechanization, Patterson P. Hilaire
Effects Of Critical Reflection On University Students’ Cognitive Achievement In Agricultural Mechanization, Patterson P. Hilaire
Graduate Theses and Dissertations
Experiential learning continues to play a vital role in agricultural education and mechanization laboratories (Shoulders & Myers, 2013). An essential component of experiential learning is critical reflection. Critical reflection helps students process and construct meaning from laboratory experiences. A study conducted by Shoulders and Myers (2013) revealed that only 15.4% of the agricultural educators the researchers interviewed incorporated reflective practices laboratory experiences. The purpose of this study was to evaluate the effect of critical reflection on students’ achievement following five agricultural mechanization laboratory activities. The results from this study revealed that critical reflection had a consistently positive effect on immediate …
Effects Of Genre Tag Complexity On Popular Music Perception And Enjoyment, Lauren Shepherd
Effects Of Genre Tag Complexity On Popular Music Perception And Enjoyment, Lauren Shepherd
Graduate Theses and Dissertations
The popular online streaming platform Spotify added over 1400 genre tags in the last two years. Despite that numerous artists and composition competitions claim to seek projects that “transcend the traditional notion of genre,” the industry has only added more complex and mystifying genre labels. This dichotomy between artists and industry ignores the effects these labels have on consumers. Do more complex genre tags enhance the listening experience for the average consumer by providing additional information about what they are about to hear? The current research seeks to examine the effects of the granularity of genre tags on popular music …
Music, Language, And Rhythmic Timing, Rhimmon Simchy-Gross
Music, Language, And Rhythmic Timing, Rhimmon Simchy-Gross
Graduate Theses and Dissertations
Neural, perceptual, and cognitive oscillations synchronize with rhythmic events in both speech (Luo & Poeppel, 2007) and music (Snyder & Large, 2005). This synchronization decreases perceptual thresholds to temporally predictable events (Lawrance et al., 2014), improves task performance (Ellis & Jones, 2010), and enables speech intelligibility (Peelle & Davis, 2012). Despite implications of music-language transfer effects for improving language outcomes (Gordon et al., 2015), proposals that shared neural and cognitive resources underlie music and speech rhythm perception (e.g., Tierney & Kraus, 2014) are not yet substantiated. The present research aimed to explore this potential overlap by testing whether music-induced oscillations …
Familiarization Through Ambient Images Alone, Nia Imani Gipson
Familiarization Through Ambient Images Alone, Nia Imani Gipson
Graduate Theses and Dissertations
The term “ambient images” has begun to show up in much of the current literature on facial recognition. Ambient images refer to naturally occurring views of a face that captures the idiosyncratic ways in which a target face may vary (Ritchie & Burton, 2017). Much of the literature on ambient images have concluded that exposing people to ambient images of a target face can lead to improved facial recognition for that target face. Some studies have even suggested that familiarity is the result of increased exposure to ambient images of a target face (Burton, Kramer, Ritchie, & Jenkins, 2016). The …
Electrophysiological Correlates Of Visual Object Category Formation In A Prototype-Distortion Task, Stephanie Marie Long
Electrophysiological Correlates Of Visual Object Category Formation In A Prototype-Distortion Task, Stephanie Marie Long
Graduate Theses and Dissertations
In perceptual learning studies, participants engage in extensive training in the discrimination of visual stimuli in order to modulate perceptual performance. Much of the literature in perceptual learning has looked at the induction of the reorganization of low-level representations in V1. However, much remains to be understood about the mechanisms behind how the adult brain (an expert in visual object categorization) extracts high-level visual objects from the environment and categorically represents them in the cortical visual hierarchy. Here, I used event-related potentials (ERPs) to investigate the neural mechanisms involved in object representation formation during a hybrid visual search and prototype …
