A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan Oct 2017

A Simulated Walk In Nature: Testing Predictions From The Attention Restoration Theory, Corey Crossan

Electronic Thesis and Dissertation Repository

Attention Restoration Theory (ART) predicts that top-down processing during everyday activities can cause attentional fatigue and that bottom-up processing that occurs when people experience nature will be restorative (Kaplan, 1995). The present study examined this prediction by exposing participants to three different conditions using a repeated measures design: a control condition during which participants walked on a typical treadmill, a nature/restorative condition during which participants walked on the same treadmill, experiencing a simulated nature walk, and a perturbation condition that included the same simulated nature scene but also required top-down processing during the walk. The findings supported ART predictions. As …


The Effects Of Presession Attention On The Acquisition Of Tacts And Intraverbals, Mirela Cengher Sep 2017

The Effects Of Presession Attention On The Acquisition Of Tacts And Intraverbals, Mirela Cengher

Dissertations, Theses, and Capstone Projects

This study examined the effects of presession attention on the acquisition of tacts (Experiment 1) and intraverbals (Experiment 2) in children with Autism Spectrum Disorders. There were 3 conditions in each experiment. In the first 2 conditions, the experimenter first exposed the participants to a 15-min interval of either presession attention (PA) or no presession attention (NPA), then immediately conducted a teaching session. The third condition was a control condition, which involved no pressession interval or teaching procedures. The consequence for emitting tacts and intraverbals consisted of different forms of attention (e.g., praise and clapping). Across experiments, all participants acquired …


Semantic Attention: Effects Of Modality, Lexicality And Semantic Content, David Britton Sep 2017

Semantic Attention: Effects Of Modality, Lexicality And Semantic Content, David Britton

Dissertations, Theses, and Capstone Projects

Since the discovery of the Stroop Effect in 1935 questions about the role of language vs. non-lexical stimuli in selective attention remain. Early researchers attributed the powerful distracting influence shown in the Stroop task, naming the color in which a spelled word is printed when incongruent with the color name the word spells, to an automaticity of language that gives it privileged access to meaning, but many others since have shown various ways to reduce or even reverse this distracting effect of an incongruent word. This study addresses this by using EEG to record neural activity along with reaction time …


Understanding The Role Of The Ventrolateral Prefrontal Cortex In Emotional Memory Using Transcranial Direct Current Stimulation And Transcranial Magnetic Stimulation, R. Rachel Weintraub-Brevda Sep 2017

Understanding The Role Of The Ventrolateral Prefrontal Cortex In Emotional Memory Using Transcranial Direct Current Stimulation And Transcranial Magnetic Stimulation, R. Rachel Weintraub-Brevda

Dissertations, Theses, and Capstone Projects

Emotional stimuli can have both beneficial and detrimental effects on memory, such that emotional stimuli can be distracting from current neutral working memory goals, while also leading to enhanced episodic memory for the distracting emotional stimuli. Recent evidence suggests that the ventrolateral prefrontal cortex (VLPFC) has multiple roles in the enhancing effects of emotion on memory through top-down/controlled processes, including 1) coping with negative distraction and 2) elaborative encoding of negative information. Additionally, previous research has alluded to hemispheric differences in the VLPFC (Chapter 1). However, previous research has been correlational, with no strong laterality tests of the VLPFC. Two …


Social Media And Cognition, Ana C. Ruiz Pardo Aug 2017

Social Media And Cognition, Ana C. Ruiz Pardo

Electronic Thesis and Dissertation Repository

Social media is an inescapable platform for sharing media and connecting with others. This thesis investigated how social media impacts cognition; specifically, attention. Study 1 investigated typical social media usage patterns and helped gauge which SM platform was most popular. Study 1 revealed three main platforms people used most often: Facebook, Instagram, and Snapchat. Facebook was reported as the most popular social media platform. Study 2 investigated how a social media post impacts cognition. It was hypothesized that participants who posted, with the intention of provoking a reaction from their followers, on their social media prior to performing a cognitive …


Efficacy Of Short-Term Emotional Regulation Training On Interference During Cognitive Tasks, Kerry Margaret Cannity Aug 2017

Efficacy Of Short-Term Emotional Regulation Training On Interference During Cognitive Tasks, Kerry Margaret Cannity

Doctoral Dissertations

The experience of emotion and attempts to regulate it are universal human phenomena. Emotion regulation is used to alter the affective intensity or tone, behaviors, and consequences associated with an emotional experience. This study examined how two common emotional regulation strategies (mindfulness and distraction) affect attentional performance following a negative mood induction via film. While previous literature has compared emotional regulation strategies’ effects on a variety of outcomes, the efficacy of these strategies to reduce cognitive interference caused by negative mood has not been examined. Both mindfulness and distraction are hypothesized to occur through the Attention Deployment mechanism of the …


The Effects Of Alcohol On Visual Attention, Amber M. Robinson Jul 2017

The Effects Of Alcohol On Visual Attention, Amber M. Robinson

Electronic Thesis and Dissertation Repository

Alcohol has been shown to have a variety of effects on cognitive performance in humans; the present study tested the effects of alcohol on visual selective attention using three different paradigms. The effects of alcohol intoxication over a broad range of blood alcohol concentrations (average between 0.01 and 0.08) were evaluated for change blindness, inattentional blindness, and multiple object tracking. Alcohol was found to impair inattentional blindness performance, negatively affecting participants’ ability to notice the unexpected changes presented. This result is interpreted as support for the alcohol myopia theory. No significant effects of alcohol were found for change blindness or …


Individual Differences In The Allocation Of Visual Attention During Navigation, Mikayla Keller Jul 2017

Individual Differences In The Allocation Of Visual Attention During Navigation, Mikayla Keller

Electronic Thesis and Dissertation Repository

There are large individual differences in the ability to create an accurate mental representation (i.e., a cognitive map) of a novel environment, yet the factors underlying cognitive map accuracy remain unclear. Given the roles that landmarks and cognitive map accuracy play in successful navigation, the current study examined whether differences in the landmarks that individuals look at while navigating are related to differences in cognitive map accuracy. Participants completed a battery of spatial tests: some that assessed spatial skills prior to a navigation task, and others that tested memory for the environment following exploration of a virtual world. Results indicated …


The Cognitive Effects Of Light Color Temperature, Lauren Hartstein Jul 2017

The Cognitive Effects Of Light Color Temperature, Lauren Hartstein

Doctoral Dissertations

The goal of the current studies is to explore the conditions by which light color temperature impacts cognitive abilities and the development of this relationship. Experiments 1 and 1A explored whether exposure to light fluctuating around a central color temperature leads to increases in attention in adult participants. Results showed that, under the dynamic lighting condition, participants’ showed a significant decrease in reaction time on a measure of sustained attention, beyond those of a static light source at a cooler color temperature. Experiment 2 tested whether preschool-aged and 7-year-old participants would show increases in attention and cognitive flexibility after exposure …


The Effect Of Interruptions During A Laparoscopy Skills Training Task, Brandon Allan Fluegel Jul 2017

The Effect Of Interruptions During A Laparoscopy Skills Training Task, Brandon Allan Fluegel

Psychology Theses & Dissertations

The goal of the present study was to examine how interruptions during a laparoscopic skills training task affected task performance. Undergraduate students completed a task that required them to pick up and transfer colored objects in a specific, predetermined sequence. The number of colored objects in the sequence was varied to produce three levels of task demand. During execution of the primary task, participants were interrupted by auditory task-irrelevant communication. The temporal length of interruptions was also manipulated to produce three levels of interruption duration. Results showed that participants made significantly more sequence errors in the high demand condition than …


Attentional And Emotional Consequences Of Emotional Acceptance And Suppression In An Elevated Anxiety Sample, Natalie Arbid May 2017

Attentional And Emotional Consequences Of Emotional Acceptance And Suppression In An Elevated Anxiety Sample, Natalie Arbid

Graduate Masters Theses

Acceptance-based strategies have been incorporated into behavioral therapies for anxiety and other disorders (e.g., Roemer & Orsillo, 2009). Experimental literature is in need of better, more nuances assessment of the consequences of acceptance (Kohl, Rief & Glombiewski, 2012). Therefore, this study specifically examined the way in which acceptance can increase attentional flexibility and recovery from stress, which are important factors in the maintenance of anxiety disorders (Cisler & Koster, 2010). This experimental study compared acceptance and suppression of emotional experiences, following exposure to fearful stimuli (i.e., images and film clip), to a control condition.

Results indicated that there was no …


The Emotional Attentional Blink: A Review And Research Agenda, Jonathan Keefe May 2017

The Emotional Attentional Blink: A Review And Research Agenda, Jonathan Keefe

Senior Theses

The Emotional Attentional Blink (EAB) refers to a temporary impairment in the ability to identify a single target when that target is preceded by an emotionally salient distractor, such as a disgusting, violent or erotic image (Most, Smith, Cooter, Levy, & Zald, 2007; Ciesielski, Armstrong, Zald, & Olatunji, 2010). The EAB represents a failure to perform an endogenous target discrimination task as a result of exogenous attentional capture by an emotional image, making it an effective medium through which to study the intersection of these two attentional systems. The present review seeks to relate existing models of the EAB to …


The Effects Of Pointing Gestures On Visual Attention, Samaria J. Hamilton May 2017

The Effects Of Pointing Gestures On Visual Attention, Samaria J. Hamilton

Honors College Theses

Visual attention is a process that involves concentrating on select features, such as sensory cues, within the complex environment. Sensory cues within the visual field capture and redirect our attention. Previous research on eye gaze revealed that direct gaze captures attention. In the present study, pointing gestures and motion cues were tested together in a visual search task to examine their effects on attention. Participants were instructed to identify a target letter presented on one of four hands. Initially, two hands displayed a pointing gesture while the other two displayed an open gesture. Next, a target letter appeared, one open …


The Effects Of Meditation On Brain Organization And The Implications For Treating Adhd, Talia Gibson May 2017

The Effects Of Meditation On Brain Organization And The Implications For Treating Adhd, Talia Gibson

Honors Projects

Attention-deficit/hyperactivity disorder (ADHD) has recently become increasingly diagnosed for children and adolescents. As of now, the most common treatment method is medication, with the purpose of changing brain organization. Recently, however, there has been increasing interest in the use of mindfulness meditation to treat the symptoms associated with ADHD. In this paper, eleven different studies, which have introduced mindfulness meditation as a treatment method for ADHD, are analyzed. The studies measure the degree to which mindfulness meditation improves common symptoms associated with ADHD. These symptoms include attentional problems, reduced mindful awareness, externalizing and internalizing problems, reduced self-control, impaired social behavior, …


Attention To Melodic Versus Phonetic Cues In 8-Month-Old Infants, Alexandra M. Ryken Apr 2017

Attention To Melodic Versus Phonetic Cues In 8-Month-Old Infants, Alexandra M. Ryken

Undergraduate Honours Theses

Infant listeners have very sophisticated auditory processing skills. In the music domain, infants as young as 6-months of age can recognize familiar and novel melodies (e.g., Trainor, Wu, & Tsang, 2004), and in the speech domain 8-month-old infants can use the statistical frequency of syllables to recognize familiar and novel nonsense words (e.g., Saffran, Aslin, & Newport, 1996). Though infants can process music and speech information when presented separately, there has been little research to date on whether infants can process information from both streams simultaneously. Auditory streams such as lullabies often contain both a melody and lyrics, but can …


Speed-Accuracy Trade-Off In Value-Driven Attentional Capture, Yuxuan Li Apr 2017

Speed-Accuracy Trade-Off In Value-Driven Attentional Capture, Yuxuan Li

Senior Theses and Projects

Attention is traditionally divided into two types: voluntary, goal-directed attention and involuntary, stimulus-driven attention (Corbetta & Shulman, 2002; Theeuwes, 2010). Seminal work on value-driven attentional capture (VDAC) has shown that stimuli associated with reward during a reward learning phase slowed reaction time (RT) in a test phase even when task-irrelevant and non-salient (Anderson, Laurent, & Yantis, 2011). However, performance-contingent reward and a response deadline impose additional constraints in the VDAC paradigm: responding too quickly decreases reward likelihood and responding too late drops the reward probability to zero. Thus, to maximize reward, participants must carefully decide when to respond, potentially altering …


Are You Feeling Me?: The Role Of Attention In Physiological Empathetic Responses, Gabriela Paganini Jan 2017

Are You Feeling Me?: The Role Of Attention In Physiological Empathetic Responses, Gabriela Paganini

Scripps Senior Theses

This study examined the role of attention and trait empathy within the production of neural facial mimicry responses that have been previously found to be associated with the experience of empathy. More specifically, do people who have high trait empathy levels require less attention to emotional information in order to still exhibit these physiological responses than people who have lower trait empathy levels? It has previously been demonstrated that responses in the zygomaticus and corrugator muscles have been associated with the experience of empathy. College aged participants were shown series of happy, angry, and neutral faces with the amount of …


Restoration Of Attentional Deficits After Concussion, Katharine B. Earle Jan 2017

Restoration Of Attentional Deficits After Concussion, Katharine B. Earle

Cal Poly Humboldt theses and projects

Difficulties with concentration and attention are among the most prevalent symptoms experienced after concussion. Rest has been the most common form of recovery from concussion; however, new research is suggesting mild mental exertion to be an effective aid in recovery. Drawing from Attention Restoration Theory, this study evaluated the idea that cognitive engagement with natural environments can mitigate post-concussion directed-attention deficits. A between subjects repeated measures design was used to test directed-attention after video exposure to restorative/nature and nonrestorative/city environments. Measures of mood, connectedness to environment, and symptomology scores were also collected. No meaningful difference between exposure type was found …


The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore Jan 2017

The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore

Graduate Theses and Dissertations

I examined the role of memory and attention in prospective person memory. Prospective person memory involves being on the lookout for a person with the goal of completing some task (i.e., contacting the authorities) upon encountering the person. Success at prospective person memory tasks in lab and field based studies is rather low (i.e., less than 10% of people report encountering the person). In the current study the prospective person memory task involved a simulated search for a missing person. I manipulated attention to the missing person and strategic monitoring, which involves being in retrieval mode and searching for cues. …


The Effect Of Action Video Game Play On The Distribution And Resolution Of Visuospatial Attention, Andrew Thomas Fent Jan 2017

The Effect Of Action Video Game Play On The Distribution And Resolution Of Visuospatial Attention, Andrew Thomas Fent

Browse all Theses and Dissertations

Previous research has found that Video Game Players, or VGPs, perform better on a variety of attention tasks (i.e. attentional blink, useful field of view, flanker compatibility, etc.) as compared to Non-Video Game Players, or NVGPs. We examined the extent of this previously observed VGP attentional advantage on a target identification task. Most VGP studies have examined the VGP advantage on tasks that primarily require detection but not identification. Identification is an important process beyond detection for encoding and later retrieving information. VGPs and NVGPs were tested on briefly flashed strings of digits subtending less than 10 degrees of visual …


Children's Letter Learning: The Effect Of Manipulating Visual Complexity On Children's Letter Learning, Bahar Amani Jan 2017

Children's Letter Learning: The Effect Of Manipulating Visual Complexity On Children's Letter Learning, Bahar Amani

Theses and Dissertations (Comprehensive)

As a growing presence in homes and schools, technology plays an important role in the way that children learn in their environment. The early integration of technology within education reflects the promise of computer-based educational tools to facilitate early learning in children (Grant, Wood, Gottardo, Evans, Phillips, & Savage, 2012). Young learners are reported to be challenged with high levels of distractibility that can hinder their ability to learn in particular conditions and contexts (Fisher, Godwin, & Seltman, 2014). This can be a problem when considering that educational materials are often designed to be elaborate to keep young learners interested. …
