Department of Psychology Faculty Scholarship and Creative Works

The goal of this Research Topic was to bring together diverse scientific perspectives on lateralized brain mechanisms underlying emotion, motivation, and memory. The Topic resulted in eight articles, three of which report original research and five of which review and synthesize past research with the aim of developing new hypotheses and theory. A range of international experts with diverse backgrounds, theoretical perspectives, and experimental methods contributed to the Topic. Contributions strongly reflect this diversity, ranging from examining pupil dilation in response to viewing Rembrandt portraits to understanding how caffeine supplementation influences levels of spatial processing. In all cases, the authors …

Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan

Electronic Theses and Dissertations

Individuals who suffer from amyotrophic lateral sclerosis (ALS) have a loss of motor control and possibly the loss of speech. A brain-computer interface (BCI) provides a means for communication through nonmuscular control. Visual BCIs have shown the highest potential when compared to other modalities; nonetheless, visual attention concepts are largely ignored during the development of BCI paradigms. Additionally, individual performance differences and personal preference are not considered in paradigm development. The traditional method to discover the best paradigm for the individual user is trial and error. Visual attention research and personal preference provide the building blocks and guidelines to develop …

The Phenomenon Of Abstract Cognition Among Scholastic Chess Participants: A Case Study, Brent C. Laws

Electronic Theses and Dissertations

A qualitative investigation was conducted to explore the phenomenon of abstract cognition among a purposive sample of 5 secondary scholastic chess club participants. The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …

Attention Modulates Erp Indices Of The Precedence Effect, Benjamin H. Zobel

Masters Theses

When presented with two identical sounds from different locations separated by a short onset asynchrony, listeners report hearing a single source at the location of the lead sound, a phenomenon called the precedence effect (Wallach et al., 1949; Haas, 1951). When the onset asynchrony is above echo threshold, listeners report hearing the lead and lag sounds as separate sources with distinct locations. Event-related potential (ERP) studies have shown that perception of separate sound sources is accompanied by an object-related negativity (ORN) 100-250 ms after onset and a late posterior positivity (LP) 300-500 ms after onset (Sanders et al., 2008; Sanders …

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …

Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree

Masters Theses & Specialist Projects

The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …

How Attention And Beat Perception Modulate Neural Entrainment To Rhythm, Aaron Wc Gibbings

Electronic Thesis and Dissertation Repository

Recently, steady-state evoked potentials (SS-EPs) at the frequency of the beat have been observed in electroencephalograms (EEG; Nozaradan et al., 2011, 2012). Previous studies involved participants actively attending to isochronous sequences and repeating rhythms. Here we assessed whether neural enhancement of SS-EPs at beat-related frequencies occurred when (1) participants did not attend to the rhythms, and (2) the rhythm was novel and did not repeat.

When participants listened to rhythms that contained a beat SS-EP enhancement was larger during attended rhythms than when participants were distracted by another task, although SS-EPs were still present in all conditions. SS-EP enhancement therefore …

The Relationship Between Implicit And Explicit Processing In Statistical Language Learning, Nicolette B. Noonan

Electronic Thesis and Dissertation Repository

Statistical language learning is an implicit process wherein language learners track sequential statistics in fluent speech, and may it facilitate the learning of word boundaries. This process is well studied, however, the cognitive mechanisms supporting it remain poorly understood. The present thesis investigated whether domain-specific or cross-domain explicit working memory engagement would impair implicit statistical learning of word boundaries in fluent speech. Participants (n = 110) were exposed to an implicit statistical word segmentation paradigm while concurrently engaged in no other task (control), or an explicit domain- specific (verbal) or cross-domain (visuospatial) working memory task of either low- or high- …

Holding A Stick At Both Ends: On Faces And Expertise, Assaf Harel, Dwight J. Kravitz, Chris I. Baker

Psychology Faculty Publications

Ever since Diamond and Carey's (1986) seminal work, object expertise has often been viewed through the prism of face perception (for a thorough discussion, see Tanaka and Gauthier, 1997; Sheinberg and Tarr, 2010). According to Wong and Wong (2014, W&W), however, this emphasis has simply been a response to the question of modularity of face perception, and has not been about expertise in and of itself. It is precisely this conflation of questions of expertise and modularity, the consequent focus on FFA, and the detrimental effect this had on the field of object expertise research that we discussed as part …

An Evaluation Of Various Safmeds Procedures, Shawn Patrick Quigley

Dissertations

Lindsley developed Say-All-Fast-Minute-Every-Day-Shuffled, or SAFMEDS, in the late 1970’s to enhance the typical use of flashcards (Graf & Auman, 2005). The acronym was developed specifically to guide the learner’s behavior when using flashcards. A review of SAFMEDS research indicates it has been utilized with children, college students and older adults with and without disabilities. The literature also indicates the SAFMEDS procedures used are not well documented or have multiple variations limiting practitioners’ ability to know what procedure to use and when. Furthermore, future SAFMEDS research is hampered by variations in the independent variable (i.e., SAFMEDS). The purpose of this study …

Incarceration And Reintegration: How It Impacts Mental Health, April M. Marier, Alex Alfredo Reyes

Electronic Theses, Projects, and Dissertations

ABSTRACT

Background: Previous criminal justice policies have been non-effective leading to overpopulated prisons and unsuccessful reintegration. There is a lack of effective supportive and/or rehabilitative services resulting in high rates of recidivism and mental health implications. Objective: This study investigated the perceived impact that incarceration and reintegration with little to no supportive and/or rehabilitative services has on the mental health status of an individual. The emphasis was on participant perception and not on professional reports because of underreporting and lack of attention to mental health in the criminal justice system. Methods: Focus groups in the Inland Empire and Coachella Valley …

Apologies Of The Rich And Famous: Cultural, Cognitive, And Social Explanations Of Why We Care And Why We Forgive, Janet M. Ruane, Karen Cerulo

Department of Sociology Faculty Scholarship and Creative Works

In recent years, U.S. and other Western media have inundated the public with celebrity apologies. The public (measured via representative opinion polls) then expresses clear ideas about who deserves forgiveness. Is forgiveness highly individualized or tied to broader social, cultural, and cognitive factors? To answer this question, we analyzed 183 celebrity apologies offered between October 1, 2000, and October 1, 2012. Results are twofold and based in both cultural and social psychological perspectives. First, we found that public forgiveness is systematically tied to discursive characteristics of apologies—particularly sequential structures. Certain sequences appear to cognitively prime the public, creating associative links …

A Mindfulness-Based Intervention To Reduce Stress In Undergraduates., Dirk Anthony Dorsel

College of Arts & Sciences Senior Honors Theses

This study piloted a mindfulness-based intervention to reduce stress in university undergraduates, and explore effects on psychological and biological indicators of stress. Mindfulness is “the awareness that emerges through paying attention on purpose, in the present moment and non-judgmentally to the unfolding of experience moment-by-moment” (Kabat-Zinn, 1994). The one week mindfulness intervention used audiobased mindfulness tracks recorded by Clinical Psychologist Paul Salmon. These tracks taught the basics of mindfulness. Participants were asked to listen to the tracks for 30 minutes a day for five days of the intervention. Perceived stress, self-reported anxiety, self-reported depression, heart rate and skin conductance were …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn

Undergraduate Honors Theses

The presence of music is a visceral part of the human experience and its influence on cognitive function is a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of mood and arousal and their influence on attention, thus the purpose of this study. Fifty undergraduate students currently enrolled at the University of Western Ontario were recruited for this study. Given that music is a highly subjective experience, participants rated an assortment of music clips on …

Effects Of Perceptual Fluency On Reasoning And Pupil Dilation, Juan Diego Guevara Pinto

Honors College Theses

Research on perceptual disfluency has examined the effects of perceptually demanding stimuli on information processing and reasoning, suggesting that disfluent stimuli elicit slower and more effortful processing. Recent criticism of perceptual disfluency, however, suggests that the effects disfluent stimuli have on processing are marginal, and that they are mediated by individual differences. Participants completed a computerized reasoning task presented in either a fluent (i.e., easy-to-read font) or disfluent format (i.e., hard-to-read font) while pupil diameter was measured by an eye-tracker system. Pupillometry is an established reliable measure of mental activity that reflects differences in cognitive load. Results showed no performance …

Selective Effects Of Selective Attention, Katherine Camille Moen

Seton Hall University Dissertations and Theses (ETDs)

Selective Attention is the process by which an individual attends to one stimulus while ignoring other distracting stimuli. Selective attention at encoding has been found to consistently impair memory performance. However, little research has found conclusive evidence as to the impact of selective attention during initial retrieval, and how that impacts retrieval on later tests, or the influence of the types of stimuli that participants are ignoring. The following series of experiments outline how selective attention impairs memory immediately and after a delay, during encoding and retrieval. Experiments 1-3 manipulated attention during retrieval. Experiment 1 found that selective attention during …

The Effects Of Musical Mood And Musical Arousal On Visual Attention, Angela B. Marti Marca, Tram Nguyen, Jessica Grahn Dr.

Undergraduate Honors Posters

The presence of music is a visceral part of the human experience and its influence on cognitive function has become a growing area of research in psychology. In particular, perceptual properties of music (mood and arousal) have been shown to significantly affect performance. There has been minimal research in the field on the interaction of these perceptual properties and their influence on attentional processes. This research study focused on the effects of musical mood and musical arousal on visual attention. Given that music is a highly subjective experience, participants were asked to rate different music clips on independent dimensions of …

Modality Switching Within Conditional Reasoning, Nathaniel A. Young

Student Honors Theses

The format in which humans represent knowledge is still not known. Two perspectives that explain the way in which humans represent knowledge are the amodal and modal perspectives. Recently. a modality switching effect was found during a property verification task. The modality switching effect is a delay in response time in verifying the property of an object in a modality that is different from the previously verified property of a different object. This effect is often presented as evidence to support the modal perspective, but it has not been found in a task more complex than property verification. The goal …

Direct Control Of Visual Perception With Phase-Specific Modulation Of Posterior Parietal Cortex, Andrew Jaegle, Tony Ro

Publications and Research

We examined the causal relationship between the phase of alpha oscillations (9–12 Hz) and conscious visual perception using rhythmic TMS (rTMS) while simultaneously recording EEG activity. rTMS of posterior parietal cortex at an alpha frequency (10 Hz), but not occipital or sham rTMS, both entrained the phase of subsequent alpha oscillatory activity and produced a phase-dependent change on subsequent visual perception, with lower discrimination accuracy for targets presented at one phase of the alpha oscillatory waveform than for targets presented at the opposite phase. By extrinsically manipulating the phase of alpha before stimulus presentation, we provide direct evidence that the …

A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend, Christopher Donkin

Joseph W. Houpt

As a fundamental part of our daily lives, visual word processing has received much attention in the psychological literature. Despite the well established advantage of perceiving letters in a word or in a pseudoword over letters alone or in random sequences using accuracy, a comparable effect using response times has been elusive. Some researchers continue to question whether the advantage due to word context is perceptual. We use the capacity coefficient, a well established, response time based measure of efficiency to provide evidence of word processing as a particularly efficient perceptual process to complement those results from the accuracy domain.

The Effects Of Alternate-Line Shading On Visual Search In Grid-Based Graphic Designs, Michael P. Lee

Theses and Dissertations--Psychology

Objective: The goal of this research was to determine whether alternate-line shading (zebra-striping) of grid-based displays affects the strategy (i.e., “visual flow”) and efficiency of serial search. Background: Grids, matrices, and tables are commonly used to organize information. A number of design techniques and psychological principles are relevant to how viewers’ eyes can be guided through such visual works. One common technique for grids, “zebra-striping,” is intended to guide eyes through the design, or “create visual flow” by alternating shaded and unshaded rows or columns. Method: 13 participants completed a visual serial search task. The target was embedded in a …

Using Noninvasive Brain Measurement To Explore The Psychological Effects Of Computer Malfunctions On Users During Human-Computer Interactions, Leanne M. Hirshfield, Philip Bobko, Alex Barelka, Stuart H. Hirshfield, Mathew T. Farrington, Spencer Gulbronson, Diane Paverman

Management Faculty Publications

In today’s technologically driven world, there is a need to better understand the ways that common computer malfunctions affect computer users. These malfunctions may have measurable influences on computer user’s cognitive, emotional, and behavioral responses. An experiment was conducted where participants conducted a series of web search tasks while wearing functional nearinfrared spectroscopy (fNIRS) and galvanic skin response sensors. Two computer malfunctions were introduced during the sessions which had the potential to influence correlates of user trust and suspicion. Surveys were given after each session to measure user’s perceived emotional state, cognitive load, and perceived trust. Results suggest that fNIRS …

Are Individuals Fickle-Minded?, Mathew D. Mccubbins, Mark Turner

Faculty Scholarship

Game theory has been used to model large-scale social events — such as constitutional law, democratic stability, standard setting, gender roles, social movements, communication, markets, the selection of officials by means of elections, coalition formation, resource allocation, distribution of goods, and war — as the aggregate result of individual choices in interdependent decision-making. Game theory in this way assumes methodological individualism. The widespread observation that game theory predictions do not in general match observation has led to many attempts to repair game theory by creating behavioral game theory, which adds corrective terms to the game theoretic predictions in the hope …

Examining The Intersection Of The Cognitive Advantages And Disadvantages Of The Bilingual Brain, Irina Rabkina

Scripps Senior Theses

Two conflicting findings characterize cognitive processing accompanying bilingualism. The “bilingual advantage” refers to improved cognitive performance for bilingual compared to monolingual participants. Most bilingual advantages fall under the umbrella of cognitive control mechanisms, most frequently demonstrated using the Stroop task and the Simon task (e.g., Bialystok, 2008; Coderre, Van Heuven, & Conklin, 2013). The “bilingual disadvantage,” on the other hand, refers to bilinguals’ diminished performance on tasks that require word retrieval or switching between languages. This study examined the intersection of the bilingual advantage and the bilingual disadvantage to investigate whether they stem from a single cognitive control process. The …

We’Ll Meet Again: Revealing Distributional And Temporal Patterns Of Social Contact, Thorsten Pachur, Lael J. Schooler, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

What are the dynamics and regularities underlying social contact, and how can contact with the people in one’s social network be predicted? In order to characterize distributional and temporal patterns underlying contact probability, we asked 40 participants to keep a diary of their social contacts for 100 consecutive days. Using a memory framework previously used to study environmental regularities, we predicted that the probability of future contact would follow in systematic ways from the frequency, recency, and spacing of previous contact. The distribution of contact probability across the members of a person’s social network was highly skewed, following an exponential …
