Out With The Humans, In With The Machines?: Investigating The Behavioral And Psychological Effects Of Replacing Human Advisors With A Machine, Andrew Prahl, Lyn Van Swol Apr 2021

Out With The Humans, In With The Machines?: Investigating The Behavioral And Psychological Effects Of Replacing Human Advisors With A Machine, Andrew Prahl, Lyn Van Swol

Human-Machine Communication

This study investigates the effects of task demonstrability and replacing a human advisor with a machine advisor. Outcome measures include advice-utilization (trust), the perception of advisors, and decision-maker emotions. Participants were randomly assigned to make a series of forecasts dealing with either humanitarian planning (low demonstrability) or management (high demonstrability). Participants received advice from either a machine advisor only, a human advisor only, or their advisor was replaced with the other type of advisor (human/machine) midway through the experiment. Decision-makers rated human advisors as more expert, more useful, and more similar. Perception effects were strongest when a human advisor was …


Perception Of Facial Expressions In Social Anxiety And Gaze Anxiety, Aaron Necaise Jan 2018

Perception Of Facial Expressions In Social Anxiety And Gaze Anxiety, Aaron Necaise

The Pegasus Review: UCF Undergraduate Research Journal

This study explores the relationship between gaze anxiety and the perception of facial expressions. The literature suggests that individuals experiencing Social Anxiety Disorder (SAD) might have a fear of making direct eye contact, and that these individuals also demonstrate a hypervigilance towards the eye region. Some have suggested that this increased anxiety concerning eye contact might be related to the tendency of socially anxious individuals to mislabel emotion in the faces of onlookers. An improved understanding of the cognitive biases associated with SAD could lead to more efficient intervention and assessment methods. In the present study, I used the Depression …


The Self-Reference Effect, Emotion, And Self-Esteem, Analise Mcgreal Jan 2018

The Self-Reference Effect, Emotion, And Self-Esteem, Analise Mcgreal

The Pegasus Review: UCF Undergraduate Research Journal

This study examines the effect of emotionally-charged stimuli on surprise recall rates of self-referentially processed words. In a between-subjects experimental design, 101 undergraduate students from the University of Central Florida (UCF) were randomly assigned to one of three groups (positive words, negative words, or neutral words) and presented with a list of seven adjectives describing appearance (e.g. cute, appalling, tall); experimental procedures were carried out through the UCF Qualtrics online survey design platform. After self-referential processing, a significant difference between all three groups was demonstrated by completion of a one-way ANOVA, with recall rates decreasing from the neutral, to the …


The Influence Of Emotional Stimuli On Cognitive Performance In Relation To Delusion Intensity In Schizophrenia, Diana Orem Jan 2009

The Influence Of Emotional Stimuli On Cognitive Performance In Relation To Delusion Intensity In Schizophrenia, Diana Orem

Electronic Theses and Dissertations

Previous research has suggested that there are multiple psychological processes underlying delusional thought. While it appears that cognitive biases in certain reasoning and attention processes are related to delusion-proneness, the influence of emotion on these processes is not well understood. The overall objective of this study was to investigate the effect of emotional content on performance on tasks thought to measure attentional bias, preferential recall, and probabilistic reasoning in individuals with schizophrenia and demographically matched controls. In order to account for level of delusion-proneness, participants also completed a multidimensional measure of delusional thought. It was hypothesized that individuals with schizophrenia …


Applying The Appraisal Theory Of Emotionto Human-Agent Interaction, Aaron Pepe Jan 2007

Applying The Appraisal Theory Of Emotionto Human-Agent Interaction, Aaron Pepe

Electronic Theses and Dissertations

Autonomous robots are increasingly being used in everyday life; cleaning our floors, entertaining us and supplementing soldiers in the battlefield. As emotion is a key ingredient in how we interact with others, it is important that our emotional interaction with these new entities be understood. This dissertation proposes using the appraisal theory of emotion (Roseman, Scherer, Schorr, & Johnstone, 2001) to investigate how we understand and evaluate situations involving this new breed of robot. This research involves two studies; in the first study an experimental method was used in which participants interacted with a live dog, a robotic dog or …
