How Can We Build A Moral Robot?, Kristen E. Clark

Capstones

Artificial intelligence is already starting to drive our cars and make choices that affect the world economy. One day soon, we’ll have robots that can take care of our sick and elderly, and even rescue us in rescue us in emergencies. But as robots start to make decisions that matter—it’s raising questions that go far beyond engineering. We’re stating to think about ethics.

Bertram Malle and Matthias Scheutz are part of a team funded by the department of defense. It's their job to answer a question that seems straight out of a sci-fi novel: How can we build a moral …

Detecting Changes In Auditory Events, Rachael B. Peck

Masters Theses, 2010-2019

Change deafness is defined as the failure to detect the source of an above-threshold change in an auditory scene. A new paradigm recently demonstrated the phenomenon under analogous conditions to its visual counterpart, change blindness (Hall, Peck, Gaston, & Dickerson, 2015). This investigation examined the use of the paradigm through two experiments which involved the same four simultaneously presented events. Experiment 1 distributed events across a virtual 120º on the azimuth while the target event oscillated across a 60º space throughout each trial. Listeners were instructed to identify the target as soon as possible. Target rate of change was manipulated …

A Theory-Guided Investigation Of Proposed Factors That Influence The Relationship Between Cybervictimization And Psychological Adjustment In Late Adolescents, Melissa K. Hord

Electronic Theses and Dissertations

Cybervictimization is related to negative psychological adjustment (e.g., Tokunaga, 2010); however, not all cybervictims report negative outcomes, and it is not clear what factors may influence vulnerability. One possibility is that cybervictims’ attributions regarding technology-based communication impact their emotional adjustment. Those who make hostile intent attributions in ambiguous situations are more likely to experience negative outcomes (e.g., Crick & Dodge, 1994), and the inherent ambiguity of electronic communication may be particularly susceptible to misinterpretation. In addition, how individuals respond to cyber experiences may serve to either protect or damage their emotional well-being. Furthermore, those who are high in rejection sensitivity …

The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson

Exploring And Training Spatial Reasoning Via Eye Movements: Implications On Performance, Victoria A. Roach

Electronic Thesis and Dissertation Repository

This dissertation sought to determine if eye movements could serve as an indicator of success in spatial reasoning, and if eye movements associated with successful completion could be applied to strategically improve spatial reasoning.

Using the line images of Shepard and Metzler, an electronic test of mental rotations ability (EMRT) was designed. Two versions of the test were created, allowing for both a timed (6 seconds per question) and untimed testing environment. Four experiments were designed and completed to relate mental rotation ability (MRA) scores from the EMRT, to patterns in chrononumeric and visual salience data. In each experiment, participants …

The Effects Of Mindfulness On Verbal Distress Disclosure, Sara Fleming

USC Aiken Psychology Theses

The purpose of this study was to investigate the effect of a mindfulness induction on participants’ verbal distress disclosure (as measured by the Linguistic Inquiry and Word Count and State Disclosure Questionnaire). Participants were 86 undergraduate students enrolled in an Introduction to Psychology course and were randomly assigned to one of two conditions: a mindfulness condition or a control condition. Participants in the mindfulness condition engaged in a 15-minute mindfulness induction prior to disclosing about a stressful experience, while participants in the control condition listened to a neutrally valenced audio excerpt from a podcast about emotions before speaking about a …

Physiological Response To Dissonance In Musicians And Nonmusicians, Angela Beth Biehl

Masters Theses

Knowing the human response to musical dissonance could have important therapeutic implications in the music therapy setting. The listener’s musical experience could significantly impact their response and subsequently its effect in a therapeutic setting. Thus, this study aimed to examine both the psychophysiological and subjective responses to dissonance and the difference in these responses between those with high experience and those with low experience. Participating groups, categorized as high experience (HE) and low experience (LE) in terms of musical knowledge, listened to consonant and dissonant musical excerpts, and rated each excerpt on its pleasantness; their physiologic responses were measured to …

Aesthetics And Performance Evaluation Of Post-Industrial Public Parks, Adel C. Vaughn

Landscape Architecture Undergraduate Honors Theses

Post-Industrial sites are often un-utilized and deserted places that are an aesthetic, social, ecological, and physical hindrance to the realm of the cities in which they lie, however they possess enormous potential. With respectful and transformative design, these new public parks gain a variety of benefits that extend well beyond the typical benefits exhibited by public parks due to their rich history, fascinating existing structures, high levels of visual and sensorial stimulation, one-of-a-kind traits, and opportunity for impactful change. By evaluating these post-industrial public parks, knowledge can be gained about what specific elements in the landscape contribute to their overall …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …

Audible Voice In Context, Airlie S. Rose

Doctoral Dissertations

The term audible voice refers to the sound of the text experienced by the reader during silent reading. It was coined by Elbow in his Landmark Essays to help the field of composition wrestle more productively with the concept of voice in writing. In this dissertation, voice is not a metaphor. Drawing on contemporary work in psycholinguistics, cognitive psychology, and consciousness studies, it examines the phenomenon of audible voice as a form of inner speech[1]. The premise of this study is that the experience of audible voice by the reader is a unique intersection of the individual's inner landscape …

Perceptions, Stereotypes And Cognitive Resources Of Female Businesspersons: A Social Identity Approach, Amy J. Y. Lim

Dissertations and Theses Collection (Open Access)

According to the Stereotype Content Model (SCM), female businesspersons are often stereotyped and labeled either as a Career Women, competent but cold, or as a Traditional Women, warm but incompetent. This suggests that female businesspersons are generally perceived to be either competent or warm individuals, but not both. However, this may not reflect female businesspersons’ own perceptions of their competence and warmth in the workplace. Contrary to the stereotypes, evidence has demonstrated that some female businesspersons display behaviors that signal both competence and warmth. Employing a social identity approach, I propose that gender-professional identity integration (G-PII), an individual difference that …

Effects Of Motion Pattern Characteristics On The Perception Of Visual Acceleration, Alexandra S. Mueller

Electronic Thesis and Dissertation Repository

The ability to perceive visual motion is one that we use every day to perform goal-directed activities, such as intercepting or avoiding objects. As objects and observers rarely move at constant velocities, it is important to be able to detect changes in velocity. However, little attention has been paid to how we perceive visual acceleration in the literature. This thesis explored the influence of real world-relevant motion pattern characteristics on visual acceleration perception. Observers rarely see object motion with an unlimited field of view, and therefore we first examined how physically constraining the horizontal distance over which a stimulus can …

Toward A Two-Stage Model Of Free Categorization, Gregory J. Smith

Electronic Theses, Projects, and Dissertations

This research examines how comparison of objects underlies free categorization, an essential component of human cognition. Previous results using our binomial labeling task have shown that classification probabilities are affected in a graded manner as a function of similarity, i.e., the number of features shared by two objects. In a similarity rating task, people also rated objects sharing more features as more similar. However, the effect of matching features was approximately linear in the similarity task, but superadditive (exponential) in the labeling task. We hypothesize that this difference is due to the fact that people must select specific objects to …

Music Listening As Therapy, David M. Rosenblatt

Loma Linda University Electronic Theses, Dissertations & Projects

Music is a universal phenomenon and is a real, physical thing. It is processed in neural circuits that overlap with language circuits, and it exerts cognitive, emotional, and physiological effects on humans. Many of those effects are therapeutic, such as reduced symptoms of physical and mental ailments. Music is the result of the elements rhythm, melody, harmony, timbre, dynamics, and form. Rhythm is the focus of pop music, and melody is the focus of classical music. The mind perceives and organizes music in learned, consistent ways in order to generate predictions and extract meaning. There are perceptual laws and information …

"She Will Drive The ____": Verb-Based Prediction In Individuals With Parkinson Disease, Kelsey G. Santerre

Electronic Thesis and Dissertation Repository

Cognitive changes in Parkinson disease (PD) affect language processing, including sentence comprehension impairments, difficulties with processing verbs, and discourse impairments. In many theories of language comprehension, efficient language processing depends on successful implicit prediction of upcoming concepts and grammatical structures. Such prediction processes, in part, may be regulated by the neural dopaminergic system, which is markedly impaired in PD. In non-language tasks, persons with PD (PwPD) are impaired in prediction, sequencing, and probabilistic learning. However, the contributions of these dopaminergic-mediated prediction and probabilistic learning processes to language processing impairments in PD remain unexplored. We tested whether PwPD are impaired in …

Congruent Familiar Size Relationships Decrease Size Contrast Illusion, Margarita Maltseva

Electronic Thesis and Dissertation Repository

We examined the effect of familiar size of objects on size perception. Participants matched the size of a target image to the perceived size of a central image in the Ebbinghaus illusion. The central image was identical throughout all trials (a 25-mm-wide dog), but the annuli varied in physical size (12 mm vs. 37 mm), semantic category (animate vs. inanimate), and familiar real-world size (cat vs. horse for the animate category; shoe vs. car for the inanimate category). Importantly, the familiar size relationship between the center and the annuli was either congruent (e.g., dog surrounded by small shoes or large …

Culture And Cognition: The Role Culture Plays In Cognitive Development In Rural Tanzania, Eileen Seissen

It aims to answer the questions: What role does Tanzanian culture play in shaping the cognitive skills of its children? And, from an American trainers perspective, within an experiential learning environment, what cognitive differences are perceived in abstract thinking, creativity, critical thinking, and problem-solving? Nine American trainers, one Tanzanian trainer, and one Tanzanian student participated in my study. Each participant filled out a questionnaire geared toward understanding their training methods and perceptions of participant's skills and abilities. After …

Adult Attachment Styles And Psychopathic Traits: A Relationship Mediated By Empathy And Emotional Regulation?, Chelsea Heim

USC Aiken Psychology Theses

Psychopathic personality traits encompass an array of characteristics that emerge early in life and are influenced by insecure attachments between children and their parents. Disruptions in parent-child interactions also affect the development of empathy (Panfile & Laible, 2010) and emotion regulation (Waters, S. F., Virmani, E. A., Thompson, R. A., Meyer, S., Raikes, H. A. & Jochem, R., 2010), which contributes to lasting impairments in interpersonal working models about the self and others (Mack, Hackney & Pile, 2010). The interactions between psychopathy and insecure attachment, low levels of empathy, and the ability to regulate one’s emotions have been separately investigated …

Phase Change Lines, Scale Breaks And Trend Lines Using Excel 2013Tm, Neil Deochand

Masters Theses

The development of graphing skills for the behavior analyst is an ongoing process. Specialized graphing software is often expensive, not widely disseminated, and may require specific training. Dixon, et al. (2009) provided an updated task analysis (Carr & Burkholder, 1998) in the widely used platform Excel 2007. Vanselow and Bourret (2012) provided online tutorials outlining some alternate methods also using Office 2007. This article serves as an update to those task analyses with alternative and under-utilized methods in Excel 2013. To examine the utility of our recommendations twelve psychology graduate students were presented with the task analyses and the experimenters …

Eyetracking Of Coarticulatory Cue Responses In Children And Adults, Alexandra M. Cross

Electronic Thesis and Dissertation Repository

Studies examining sensitivity to coarticulatory cues during spoken word recognition have typically examined children and adults separately. The present thesis compared sensitivity to coarticulatory cues in school-aged children and adults using eyetracking. Children and adults listened to words containing congruent and incongruent coarticulatory cues while looking at a two-picture display. Contrary to theories positing weakened attention to phonetic detail in children, we observed equal or greater sensitivity to coarticulatory cues in children compared to adults. This effect was related to predictors of reading and language proficiency, and was also modulated by phoneme contrasts such that children were overly sensitive to …

A Kinematic Analysis Of Visual And Haptic Contributions To Precision Grasping In A Patient With Visual Form Agnosia And In Normally-Sighted Populations, Robert Whitwell

Electronic Thesis and Dissertation Repository

Skilled arm and hand movments designed to obtain and manipulate objects (prehension) is one of the defining features of primates. According to the two visual system hypothesis (TVSH) vision can be parsed into two systems: (1) the ventral ‘stream’ of the occipital and inferotemporal cortex which services visual perception and other cognitive functions and (2) the ‘dorsal stream’ of the occipital and posterior parietal cortex which services skilled, goal-directed actions such as prehension. A cornerstone of the TVSH is the ‘perception-action’ dissociation observed in patient DF who suffers from visual form agnosia following bilateral damage to her ventral stream. DF …

The Relationship Between Self-Determination And Client Outcomes Among The Homeless, Samuel M. Hanna

Electronic Theses, Projects, and Dissertations

This paper has attempted to determine if there is a significant relationship between self-determination and client outcomes among the homeless. The study has been based upon the conceptual framework set forth in Self-Determination Theory. The purpose of the study was to explore the relationship between self-determination and client outcomes among the homeless. Using a data collection instrument, based on empirically validated instrumentation, clients from several homeless service providers in the City of San Bernardino were assessed for the level of self-determination and autonomy support they experience within these agencies. Outcome measures included such things as whether the client was going …

This study examined the impact of social-emotional literacy instruction for at-risk adolescents ages 13 to 18 at the high school level. Of particular interest is the impact of social-emotional literacy instruction on at-risk youth Grades 9-12 in secondary high schools’ 8-week-long social-emotional literacy class through Project AWARE, particularly in the areas of suspension, expulsion, attendance, connectivity, attitude toward school, resiliency, and relational aggression rates; the data were analyzed using archival data and teacher interview. Project AWARE, the social-emotional literacy intervention examined in this study, educates and provides mentorship for at-risk students, while also providing a group educational component on relationships …

Rapid Detection And Use Of Non-Verbal Confidence Cues During Adaptive Memory Biasing, Jihyun Cha

Arts & Sciences Electronic Theses and Dissertations

Prior literature has demonstrated that participants use probabilistic, verbal memory cues (‘Likely Old’ or ‘Likely New’) to adaptively bias their recognition judgments. Here we tested whether this is more effective when the cues are the actual videotaped responses of others taking the same recognition test, based on the possibility that observers might use non-verbal confidence signs to modulate their degree of cue reliance on each trial. Experiment 1 demonstrated observers could reliably rate the confidence of others (Models) from single recognition responses (‘old’ or ‘new’) and that when doing so, the latency of the model’s response was the primary influence, …

The Effect Of Global And Local Processing In The Attentional Blink, Ashley Kalavritinos

Senior Honors Projects, 2010-2019

The attentional blink (AB) is an individual’s inability to perceive the second of two targets presented in a rapid serial visual presentation (RSVP). The constructs of global and local attention have been a principle concern in modern psychology. The perception of an object as an overall form is referred to as the global aspect, while the separate parts compose the local aspect. The purpose of this study was to explore whether the following factors affect the characteristics of an individual’s AB: (1) When target one (T1) and target two (T2) were the same or different letters (2) Whether T1 was …

The Effect Of Auditory Stimuli On Visual Time-To-Contact Perception, Chelsea L. Rugel

Senior Honors Projects, 2010-2019

Previous research has demonstrated that auditory and visual stimuli have individual effects on the accuracy of a person’s estimation of time-to-contact (TTC), the time at which two objects collide. Prior findings also suggest that there is cross-modal interference between vision and audition; however, this phenomenon has never been studied in a TTC situation. (Driver & Spence, 1998; Ichikawa & Masskura, 2006; Roseboom, Kawabe, & Nishida, 2013) In this study we attempted to fill in this research gap by examining the effect of auditory speed cues over visual speed cues in a two-dimensional TTC scenario, and by determining if an object’s …
