Investigating The Proposed Mechanisms Guiding Negative Attentional Templates, Michael Kevin Mugno

Masters Theses

To complete goal-directed visual search, information that is gathered in working memory must be sorted by relevancy to the current task. In order to bias search, attentional templates are created within the construct of visual working memory (VWM) using both endogenous and exogenous information. While most attentional templates are built around positive information, which is directly relevant to the target of search, there are cases where negative information, which is directly relevant to the search but not necessarily the target itself, may be more efficient. However, the mechanisms behind how these negative templates direct search is debated. The goal of …

Rethinking Attention Control: An Individual Differences Approach, Vincent A. Medina

LSU Doctoral Dissertations

While there is extensive literature on visual spatial attention, less is known about auditory spatial attention, especially in terms of attention control. There is also a growing literature highlighting the importance of considering individual differences in attention control ability. Given these points, the purpose of this study was twofold. The first was to understand how auditory attention control is influenced by spatial location as well as vision. The second was to examine whether individual differences in attention control ability can predict task performance in that context. We utilized two tasks for these purposes. Experiment 1a consisted of a cross-modal Stroop …

What Cognitive Processes Drive Attentional Bias, And How Does Stress Affect Them?, Colton L. Hunter

Graduate Theses and Dissertations

Attentional biases toward or away from emotionally evocative stimuli have been well documented and related to clinical outcomes such as social anxiety. Some work has suggested that stress modulates attentional biases, but there are a number of inconsistencies in this literature regarding the direction of that modulation, highlighting a need to examine moderators of that effect. Sex differences in stress effects could potentially explain this inconsistency, as acute stress can affect males and females differently. It is also possible that stress differentially influences multiple component processes underpinning attentional bias, but these processes have not been well character, and to date …

The Long-Term Effects Of Cannabis On Attention To Motion, Rachel Mccaig

Theses and Dissertations (Comprehensive)

The purpose of the following study was to investigate the long-term effects of cannabis use on attention to motion.

Methods: Cannabis users, who varied in age of onset of use, were compared to control participants after abstaining from cannabis for at least 24 hours. One-hundred and ninety-seven participants engaged in a cognitive assessment followed by a motion discrimination task and an attention to motion task. The assessment consisted of a series of standard tasks that measured a range of cognitive processes such as attention, memory, and executive functioning. The motion discrimination task assessed the participants’ abilities in discriminating between various …

Classical Conditioning Of Cognitive States, Arthur Burns

Neuroscience Honors Papers

Classical conditioning has been a fundamental concept and practice throughout the history of psychology. While classical conditioning traditionally seeks to elicit target behaviors in correlation to specific stimuli, we sought to do the same with cognitive states in place of behaviors. Specifically, we wanted to determine the effectiveness of conditioning states of cognitive arousal in human participants in conjunction with cues presented in a designed learning task. We designed a cognitive task specifically for this research, referred to as “the Tone Pitching Task”, which utilized a combination of working memory and mental processing in order to elicit cognitive arousal and …

The Role Of Top-Down Attention In Statistical Learning Of Speech, Stacey Reyes

Electronic Thesis and Dissertation Repository

Statistical learning (SL) refers to the ability to extract regularities in the environment and has been well-documented to play a key role in speech segmentation and language acquisition. Whether SL is automatic or requires top-down attention is an unresolved question, with conflicting results in the literature. The current proposal tests whether SL can occur outside the focus of attention. Participants either focused towards, or diverted their attention away from an auditory speech stream made of repeating nonsense trisyllabic words. Divided-attention participants either performed a concurrent visual task or a language-related task during exposure to the nonsense speech stream, while control …

The Effects Of Interactivity On Memory Relating To Presence In Virtual Environments, Jenny Wong

Psychological Science Undergraduate Honors Theses

The overall effectiveness of virtual environments is often linked to and measured by degrees of presence, commonly defined as the psychological sensation of “being there” (Schubert et al., 1999). Psychologists agree that attention and involvement through interactivity play a role in presence (Hartmann et al., 2015; Schubert et al., 1999; Witmer and Singer, 1998). Because attention is critical in encoding information into memory storage, looking at how memory relates to presence is another topic of interest. In this study, participants (N = 30) played through a 3D virtual reconstruction of a Pompeian house under one of two conditions: free-roam …

Effect Of Short-Storage Hrgcs On Driver Decision Behavior And Safety Concerns: Real-World Analysis And Experimental Evidence, Anne Linja

Dissertations, Master's Theses and Master's Reports

Vehicle-train collisions at highway-rail grade crossings (HRGCs) continue to be a safety concern, and despite improvements in warnings, many of these incidents are attributed to human error. In some cases, distractions other than railroad traffic, such as HRGCs with limited space between the railroad tracks and the highway intersection, may create additional cognitive burdens for drivers. We investigated the effect of HRGC type (short-storage vs. non-short storage) on driver attention and decision-making in two studies. In Study 1, we systematically analyzed 996 incidents from 2017-2019 from the Federal Railroad Administration’s Safety database. Driver decision making and outcomes were different depending …

Effects Of Spatial Language Cues On Attention And The Perception Of Ambiguous Images, Aaron Foster

Cal Poly Humboldt theses and projects

It’s a bird! It’s a plane! It’s superman!? Sometimes there are things in our world that are ambiguous. An ambiguous object, for the purposes of this thesis is any object that has more than one interpretation to it. The brain is designed to “fill in the blanks” and make sense of the world. Thus it will use anything available, like language, to help in resolving the ambiguity. Language can change how we perceive information in the world (Dils & Boroditsky, 2010) and where we direct our attention (Ostarek & Vigliocco, 2017; Estes et. al. 2008; Estes, Verges, Adelman, 2015). Language …

Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth

Doctoral Dissertations

Perceptual narrowing is a domain-general process in which infants move from a broad sensitivity to a wide range of stimuli to developing expertise within often experienced native stimuli (Maurer & Werker, 2014). One outcome of this is the own-race bias, characterized by an increasing difficulty in discriminating other-race faces with age and experience for those raised in a racially homogenous environment (Anzures, Quinn, Pascalis, Slater, Tanaka, & Lee, 2013). Recent theorists have proposed that this is due to a categorization-individuation process, wherein infants begin to categorize non-native stimuli, such as other-species’ faces, but individuate native stimuli, such as often-experienced human …

The Differences In Visuospatial Attentional Distribution Between Synesthetes And Non-Synesthetes, Identified Through Covert Visual Search, Kirsten Helena Ostbirk

Senior Projects Fall 2020

Synesthesia is a condition whereby sensory stimuli evoke unusual additional sensory perceptions and experiences, and can be identified through a visual search task. Grapheme-colour synesthetes have shown increased efficiency in visual search tasks, which some have hypothesized is a result of synesthetic colours drawing attention to the target stimulus, and have likened it to a weakened “pop-out” effect. Visual search has also been used to measure visuospatial attentional distribution, and findings from this method have supported the gradient model of attention, which proposes that cognitive resources are the most concentrated centrally in our visual field, and taper off, such that …

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 …

Visual Entrainment Of Perception-Related Neural Oscillations As A Mechanism For Maintaining Rhythmic Temporal Expectations Across A Wide Range Of Frequencies, Michael James Gray

Dissertations, Theses, and Capstone Projects

Visual sensitivity fluctuates rhythmically, in-synch with ongoing, EEG-recorded neural oscillations across a wide range of frequencies (~1-25hz). Some recent work has suggested that these perception-related neural oscillations can be entrained by rhythmic visual stimulation. Evidence is also emerging that the entrainment of ongoing oscillations in visual and auditory cortices is involved in rhythmic temporal expectations. In the introduction chapter, I attempt to bridge these bodies of literature and hypothesize that rhythmic visual stimuli automatically entrain ongoing, perception-related neural oscillations and that this mechanism supports the maintenance of rhythmic temporal expectations. Chapters 2 and 3 address this hypothesis from different angles. …

Behavioral Hypervigilance In A Normative Population, Karly Weinreb

Theses and Dissertations

Hypervigilance is conceptualized as a symptom of trauma-related disorders, however it can also occur in a normative population. To distinguish normative hypervigilance from trauma-related hypervigilance, 372 participants (123 trauma-exposed and 249 non-trauma-exposed) completed a questionnaire assessing hypervigilance in contexts. Trauma-exposed participants reported greater levels of hypervigilance in 3 contexts.

Attention As A Mechanism For Object-Object Binding In Complex Scenes, Kacie Mennie

LSU Doctoral Dissertations

The current study attempted to determine whether direct binding between objects in complex scenes occurs as a function of directed attention at encoding. In Experiment 1, participants viewed objects in one of these different types contexts: unique scenes, similar scenes, or arrays with no contextual information. Critically, only half of the objects were attended for each encoding trial. Participants then completed an associative recognition task on pairs of items created from the previously studied scenes. Test pairs consisted of two attended or unattended objects, and were associated with a unique scene, a similar scene, or an array. Evidence of binding …

Quantitative Reasoning: Individual Differences In Heart Rate And Response Latency, Abigail L. Van Nuland

MSU Graduate Theses

Math is something that all students are required to use at some point during their academic careers. Then they must use it again in the real world. Unfortunately, many students struggle with quantitative processing. In the current study, participants answered first grade level math problems in order to assess cognitive effort when solving math problem. Participants were then assigned randomly to one of two conditions; Answer or Equation. In the Answer Condition participants were asked to solve a series of math problems, whereby they were given a math equation and then they were asked to choose an answer. In the …

Long-Term Focus Of Attentional Biases, Garrett Pollert

Graduate Theses and Dissertations

Prior research regarding attentional biases, or patterns of visual attention, have focused on attention over the initial second when exposed to pictoral food stimuli. This manuscript reviews the literature regarding attentional biases in overweight/obese individuals over this timeframe for the two previously defined components of attentional bias (attentional orientation and attentional maintenance). A new component is proposed, called “attentional re-engagement,” defined as the pattern of attentional shifts towards target stimulus types over longer periods of time. Overweight/Obese and Normal-weighted participants were recruited and engaged in an Extended Dot Probe task, wherein attentional orientation, maintenance, and re-engagement were assessed using the …

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 …

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. …

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 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 …

Cognitive Fatigue: Exploring The Relationship Between The Fatigue Effect And Action Video-Game Experience, James Brooks

Theses: Doctorates and Masters

the effects of cognitive fatigue. Despite this, there remain advantages to regularly playing action video games. In Study 1, VGPs were significantly better at multitasking on the MATB-II compared to the NVGPs. Further, VGPs also demonstrated superior multitasking when driving, as they made significantly fewer traffic violations compared to NVGPs when not fatigued. VGPs demonstrated eye-movements similar to those of expert drivers; however, this did not result in any difference in performance between the two groups. There was also some evidence of a positive effect of video game training, although there was no advantage of one training technique over the …

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 …

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …
