Evaluation Of A Cognitive Training Program For Older Adults With Mild To Moderate Cognitive Decline, Kelly Bergstrom

All Graduate Theses, Dissertations, and Other Capstone Projects

Older adults often experience varying levels of cognitive decline. Several interventions intended to help slow the effects of cognitive decline have been studied, including cognitive training. Cognitive training involves engaging individuals, typically in a group setting, in exercises that target specific cognitive domains, such as attention, perceptual speed, memory, language, and executive functioning. Literature on cognitive training provides mixed support for its efficacy. The purpose of the current study was to determine whether a manualized, in-person cognitive training program for individuals with mild to moderate cognitive decline would lead to an improvement in cognitive performance. The program targeted six cognitive …

Who's That Knocking At My Door? Neural Bases Of Sound Source Identification, Guillaume Lemaitre, John A. Pyles, Andrea R. Halpern, Nicole Navolio, Matthew Lehet, Laurie M. Heller

Faculty Journal Articles

When hearing knocking on a door, a listener typically identifies both the action (forceful and repeated impacts) and the object (a thick wooden board) causing the sound. The current work studied the neural bases of sound source identification by switching listeners' attention toward these different aspects of a set of simple sounds during functional magnetic resonance imaging scanning: participants either discriminated the action or the material that caused the sounds, or they simply discriminated meaningless scrambled versions of them. Overall, discriminating action and material elicited neural activity in a left-lateralized frontoparietal network found in other studies of sound identification, wherein …

Transient Signals And Inattentional Blindness In A Multi-Object Tracking Task, Dakota B. Palmer, Yusuke Yamani, Taylor L. Bobrow, Nicole D. Karpinsky, Dean J. Krusienski

Psychology Faculty Publications

Inattentional blindness is a failure to notice an unexpected event when attention is directed elsewhere. The current study examined participants' awareness of an unexpected object that maintained luminance contrast, switched the luminance once, or repetitively flashed. One hundred twenty participants performed a dynamic tracking task on a computer monitor for which they were instructed to count the number of movement deflections of an attended set of objects while ignoring other objects. On the critical trial, an unexpected cross that did not change its luminance (control condition), switched its luminance once (switch condition), or repetitively flashed (flash condition) traveled across the …

An Analysis Of The Ego-Depletion Effects Of Emotion Versus Attention Draining Tasks: Even Emotionally Arousing Depletion Tasks Do Not Show An Ego-Depletion Effect, Savannah Binion

Senior Independent Study Theses

The theory of ego-depletion has come under intense scrutiny within the past few years. Beginning around 2010, researchers conducted meta-analyses and large replication studies that have investigated this topic, and found a wide range of evidence for and against the existence of an ego-depletion effect. Although the goal has been to determine whether this effect exists or not, the research has proved that the answer may be more complicated than that. The purpose of the current research was to examine the different theories about self-control, and to test two specific depleting tasks against a control group. The depleting tasks were …

Predicting Similarity Judgments In Intertemporal Choice With Machine Learning, Jeffrey R. Stevens, Leen-Kiat Soh

Jeffrey Stevens Publications

Similarity models of intertemporal choice are heuristics that choose based on similarity judgments of the reward amounts and time delays. Yet, we do not know how these judgments are made. Here, we use machine-learning algorithms to assess what factors predict similarity judgments and whether decision trees capture the judgment outcomes and process. We find that combining small and large values into numerical differences and ratios and arranging them in tree-like structures can predict both similarity judgments and response times. Our results suggest that we can use machine learning to not only model decision outcomes but also model how decisions are …

Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, Jeffrey R. Stevens, Jan K. Woike, Lael J. Schooler, Stefan Lindner, Thorsten Pachur

Jeffrey Stevens Publications

Analyses of the evolution of cooperation often rely on two simplifying assumptions: (i) individuals interact equally frequently with all social network members and (ii) they accurately remember each partner's past cooperation or defection. Here, we examine how more realistic, skewed patterns of contact—in which individuals interact primarily with only a subset of their network's members—influence cooperation. In addition, we test whether skewed contact patterns can counteract the decrease in cooperation caused by memory errors (i.e. forgetting). Finally, we compare two types of memory error that vary in whether forgotten interactions are replaced with random actions or with actions from previous …

Mesotocin Influences Pinyon Jay Prosociality, Juan Duque, Whitney Leichner, Holly Ahmann, Jeffrey R. Stevens

Jeffrey Stevens Publications

Many species exhibit prosocial behavior, in which one individual’s actions benefit another individual, often without an immediate benefit to itself. The neuropeptide oxytocin is an important hormonal mechanism influencing prosociality in mammals, but it is unclear whether the avian homologue mesotocin plays a similar functional role in birds. Here, we experimentally tested prosociality in pinyon jays (Gymnorhinus cyanocephalus), a highly social corvid species that spontaneously shares food with others. First, we measured prosocial preferences in a prosocial choice task with two different payoff distributions: Prosocial trials delivered food to both the subject and either an empty cage or a partner …

Heterogeneity And Parsimony In Intertemporal Choice, Michel Regenwetter, Daniel R. Cavagnaro, Anna Popova, Ying Guo, Chris Zwilling, Shiau Hong Lim, Jeffrey R. Stevens

Jeffrey Stevens Publications

Behavioral theories of intertemporal choice involve many moving parts. Most descriptive theories model how time delays and rewards are perceived, compared, and/or combined into preferences or utilities. Most behavioral studies neglect to spell out how such constructs translate into heterogeneous observable choices. We consider several broad models of transitive intertemporal preference and combine these with several mathematically formal, yet very general, models of heterogeneity. We evaluate 20 probabilistic models of intertemporal choice using binary choice data from two large-scale experiments. Our analysis documents the interplay between heterogeneity and parsimony in accounting for empirical data: We find evidence for heterogeneity across …

The Signature Of Undetected Change: An Exploratory Electrotomographic Investigation Of Gradual Change Blindness, John E. Kiat, Michael D. Dodd, Robert F. Belli, Jacob E. Cheadle

Department of Psychology: Faculty Publications

Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, “mudsplashes”), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected …

Exploring Illusions Of Height In Suit Design, Michael P. Lee

Theses and Dissertations--Psychology

Objective: The goal of this research was to explore how the design of clothing, specifically the design of the suit, can create height illusions.

Background: Taller people enjoy many advantages, such as increased income and perceived attractiveness. These advantages motivate people to try to appear taller than they actually are, and clothing experts provide advice on how to accomplish this. However, there is little empirical evidence to validate the illusory effects clothing might have on overall height perception. The few studies that have explored illusions of body size created by clothing design have been limited in two important ways – …

An Investigation Of Implicit And Explicit Memory In The Survival Memory Paradigm, Allison M. Wilck

Legacy Theses & Dissertations (2009 - 2024)

Robust support has been found for a survival processing effect on memory when information is encoded for its fitness-relevance (Nairne, Thompson, & Pandeirada, 2007). However, support for this effect has been limited to forms of memory that require intentional, explicit retrieval processes. Thus far, the literature has failed to identify the effect in implicit, automatic memory using conceptual and perceptual production tasks (McBride, Thomas, & Zimmerman, 2013; Tse & Altarriba, 2010). In the current study, an alternative implicit memory test that employs different memory processes was employed in a further attempt to examine the survival processing effect in implicit memory. …

Satisfaction Of Search (Sos) Impacts Proofreading Performance : Evidence From Eye Movements, Eliza Barach

Legacy Theses & Dissertations (2009 - 2024)

In multiple-target visual search tasks, the discovery of one target can hinder the detection of another target (i.e., “subsequent search misses”, SSMs; Cain, Adamo, & Mitroff, 2013, which are also known as “satisfaction of search” misses, SOS; Tuddenham, 1962). SSMs errors generalize to both medical and non-medical tasks (Fleck, Samei, & Mitroff, 2010) and using eye tracking methods, and a proofreading paradigm where targets are misspelled words and distractors are correctly spelled words, we document eye movement evidence of an SSM effect. Specifically, typo detection accuracy was reduced in trials containing two typos compared to trials containing a single typo. …

Investigating The Roles Of Mechanoreceptive Channels In Tactile Apparent Motion Perception: A Vibrotactile Study, Phill Kim, Philip Servos Dr.

Theses and Dissertations (Comprehensive)

Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this. The current study focused on the Rapidly Adapting (RA) channel and Slowly Adapting I (SAI) channel on the index finger. The experiment implemented vibrotactile masking stimuli to target the mechanoreceptive channels with the goal of gaining better insight into the involvement of mechanoreceptive channels in the perception of TAM. Masking stimuli were used because previous studies have used them to differentiate between different channels; a …

Identification And Replication Of Rna-Seq Gene Network Modules Associated With Depression Severity, Trang T. Le, Jonathan Savitz, Hideo Suzuki, Masaya Misaki, T. Kent Teague, Bill C. White, Julie H. Marino, Graham Wiley, Patrick M. Gaffney, Wayne C. Drevets, Brett A. Mckinney, Jerzy Bodurka

Genomic variation underlying major depressive disorder (MDD) likely involves the interaction and regulation of multiple genes in a network. Data-driven co-expression network module inference has the potential to account for variation within regulatory networks, reduce the dimensionality of RNA-Seq data, and detect significant geneexpression modules associated with depression severity. We performed an RNA-Seq gene co-expression network analysis of mRNA data obtained from the peripheral blood mononuclear cells of unmedicated MDD (n = 78) and healthy control (n = 79) subjects. Across the combined MDD and HC groups, we assigned genes into modules using hierarchical clustering with a dynamic …

The Efficacy And Mechanisms Of Conjoint Behavioral Consultation, Susan M. Sheridan, Amanda Witte, Gina Kunz, Lorey A. Wheeler, Samantha R. Angell

Department of Educational Psychology: Faculty Publications

The efficacy of conjoint behavioral consultation (CBC), a family-school partnership intervention, for teachers’ prac- tices and process skills was evaluated. Participants were 152 teachers of grades K–3 in 45 Midwest rural schools randomly assigned to treatment or control conditions. Treat- ment group teachers participated in an 8- to 10-week CBC intervention. Outcome measures were (a) self-reports of classroom practices and collaborative process skills and (b) direct observations of teachers’ use of effective behav- ioral strategies. Relative to control group participants, there was a significant positive intervention effect on CBC teachers’ self-report of appropriate behavioral strategies (b p .47, p ! …

Reasoning, Logic, And Development: Essay Review Of The Enigma Of Reason By Hugo Mercier And Dan Sperber, David Moshman

Department of Educational Psychology: Faculty Publications

In 2011, Hugo Mercier and Dan Sperber published an influential article [Mer­cier & Sperber, 2011] arguing that human reasoning evolved for the purpose of argu­mentation and serves that purpose well. Additional publications followed and now, in The Enigma of Reason, Mercier and Sperber [2017] flesh out their theory. Indi­vidual reasoning is often fallacious, in their view, because it applies reasoning beyond the scope of its evolutionary purpose. Logic, rather than a basis for reasoning, is a formalized system developed by logicians that has little connection to actual human reasoning.

This is a rich and readable book that presents many intriguing …

Psychological Ways Of Expressing Appreciations, Experiences, Thanks And Blessings In The Society, Iwasan D. Kejawa Ed.D

Department of Educational Psychology: Faculty Publications

ABSTRACT: Research has shown that one of the avenues to make aware of once experiences, appreciations and blessings is through writing a gratitude journal or memoir. By journalizing our thought by hands or electronically, it may help us focus them, according to psychologist Robert Emmons, who says that he does this routinely to remind himself; it makes apple of time to understand the meaning and importance of people and events. It has been found that one should go for a depth in writing rather than breadth, because this will help one to enjoy what one appreciates, and what to keep …

The Role Of Content Modality On The Likability Of An Online Communicator, Rebecca L. Pharmer

Honors Undergraduate Theses

With the growing popularity of social media platforms like Facebook, human interaction in online environments is increasing. As a result, social perceptions of the individuals "behind the screen" has become a topic that needs to be explored. The present study explores how the media platform (specifically Facebook post versus Video) affects perceptions of an individual with a controversial opinion. Potentially, the same content in a video format may increase the likability of the presenter in contrast to reading the same opinions in Facebook posts. The present study examined the role of alignment of opinion (agree vs. disagree with presenter) and …

Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin

Theses: Doctorates and Masters

Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …

The Effects Of Preceding Stimuli Formats On Proportional Reasoning Ability In Elementary School Students, Natalie D. Branch

Electronic Theses and Dissertations

The National Mathematics Advisory Panel (2008) described fraction knowledge as the most important, yet most underdeveloped foundational skill among students. Due to the complex nature of fraction education, this study sought to understand the underlying fraction problem-solving skill of proportional reasoning in the hopes of gaining insight into children’s problem-solving strategies in order to implement more focused educational designs. The current study examined the effects of stimuli formats on children’s proportional reasoning ability by presenting four conditions involving two formats (continuous and discrete). Previous research indicates that students perform better on continuous stimuli and the goal of this study was …
