Construct-Driven Sjts: Toward An Agenda For Future Research, Filip Lievens

Research Collection Lee Kong Chian School Of Business

A common theme running through recent research on Situational Judgment Tests (SJTs) and this special issue is the aim to improve the measurement of constructs via SJTs. Construct-driven SJTs differ from traditional SJTs in that they present a trait activating situation to test-takers and a more unidimensional set of response options that depict different trait levels. In this commentary, I frame the different papers of this special issue into a research agenda related to construct-driven SJTs. Specifically, I posit that future research should examine whether construct-driven SJTs lead to more unidimensionality at the item level, cleaner measurement of the constructs, …

Neuroticism And Ego Depletion Patterns, Parker A. Dreves

Electronic Theses and Dissertations

Self-control has been defined as the ability to override or alter an automatic response. Past research has suggested that those who are higher in the personality trait neuroticism display poorer self-control. Based on theory suggesting that self-control is a limited resource, the present study attempts to explain the relationship between neuroticism and self-control. Understanding that neuroticism is characterized by emotional instability, it follows that individuals high in neuroticism must exert more self-control in managing their negative moods, thus leaving them depleted for future acts of self-control. Participants (n = 84) completed measures of trait self-control, engaged in an emotional regulation …

Neurostructural Organization And Neocortical Projecting Neuron Distribution In A Mouse Model Of Timothy Syndrome-Mediated Autism Spectrum Disorder, Aiden L. Ford

Neural tissue was processed for either volumetric analysis through Nissl stain (8 TS2-neo, 8 WT) or …

Exploring The Impact Of Community Service On Career Exploration, Self-Determination, And Social Skills For Transition-Age Youth With Autism Spectrum Disorders, Jaimie Ciulla Timmons, Agnes Zalewska, Allison C. Hall, Sheila Fesko, Thinkwork! At The Institute For Community Inclusion At Umass Boston

ThinkWork! Publications

Bleak transition outcomes for youth with autism spectrum disorder (ASD), coupled with the surge in incidence, has led to the need for focused and innovative transition strategies. While structured community service reveals promise, documentation of how community service experiences contribute to building employment skills for youth with intellectual/developmental disability (IDD), including those with ASD, is under-researched. The purpose of this paper is to explore the impact of a community service on employment skill-building for youth with ASD. Findings from 23 qualitative interviews with a range of stakeholders showed positive perceptions in the areas of career exploration, self-determination, and social skill …

The Influence Of Values And Recipient Groups On Social Welfare Policy Opinion, Christopher Pulliam

Renée Crown University Honors Thesis Projects - All

The following paper examines how value-based considerations for social welfare policy opinion are affected by changes in the race of the program recipient. I propose a new model to understand social welfare policy opinion called the interactive model—where instrinsic considerations are tempered by extrinsic considerations. Through an original survey experiment, I find that humanitarianism and economic individualism do not have significant effects on social welfare policy opinion. However, egalitarianism is found to have a strong impact. When the race of the program recipient is changed from white to African-American, the impact of egalitarianism increases for views of Medicare. When the …

The Relationship Between Social Status Motivation And The Detection Of Trustworthy And Affiliative Cues In Faces, Christopher J. Lustgraaf

Dissertations

A prominent feature of human (and non-human primate) social group structure involves the establishment and maintenance of a social hierarchy; that is, social groups are arranged hierarchically, based on individuals’ level of status, and conspecifics who more effectively ascend this status hierarchy accrue more reproductive and resource benefits (Hawley, 1999). Thus, for any individual, other group members could be either a threat to one’s status, or an ally to assist status goals, and accurate identification of these various social targets would have adaptive utility in status maintenance or status hierarchy ascension. The current study tested the hypotheses that activation of …

“The Golden Rule”: A Portable Escape Room Designed To Promote Empathy And Playfulness In Challenging Social Contexts, Isabella Gomati

Creativity and Change Leadership Graduate Student Master's Projects

The development of a Portable Escape Room (PER) board game aims to promote empathy as one of the key skills that, for a society in constant change, is necessary to face and solve complex social challenges. The development of a PER is a way of addressing the need for both innovative and accessible tools that can be used in different sectors of the economy. The PER not only encourages creative collaboration, but it also introduces the possibility of playfulness as a bridge for learning and problem-solving in a variety of scenarios. The product itself encompasses an excellent example of a …

An Evolutionary Based Examination Of Sexting Behavior Among College Students, Scott Ploharz

Master's Theses or Doctor of Nursing Practice

Previous research has viewed the sending and receiving of sexually natured text and picture messages as risky and dangerous behavior. It is through this lens that previous research has examined the reason individuals choose to engage in sexting, and the possible effects of the behavior. The current study is the first to examine the possible adaptive reasons that individuals may choose to engage in sexting. A total of 218 participants from Fort Hays State University completed measures of their sexting behaviors, attitudes towards sexual activity, and risk tolerance. It was hypothesized that an individual participants’ endorsement of a sex consistent …

Thinking About Race: How Group Biases Interact With Ideological Principles To Yield Attitudes Toward Government Assistance, Frank John Gonzalez

Department of Political Science: Dissertations, Theses, and Student Research

When are people more likely to evaluate race-targeted government assistance based on ideological principles rather than racial prejudice? In order to answer this question, it is necessary to understand the mechanisms by which prejudice influences political attitudes. In this dissertation, I develop a theoretical model for explaining how deep-seated, automatic group biases interact with higher-order, ideological principles in order to influence attitudes toward race-targeted government assistance. I suggest group-based principles are more important than individualistic values or ingroup favoritism in explaining race-targeted policy attitudes. I argue that when people evaluate race-targeted policies, controlled neural processes translate automatic neural processes into …

Exploring The Effect Of Encoding Modality And Rehearsal Strategy On Foreign Language Vocabulary Recall, Danielle R. Bestfelt

Undergraduate Theses

Experience with a foreign language is considered a valuable skill in workplace and school settings alike. However, recent studies in the field of psychology exploring the process of acquiring a second language have limited applicability, especially for adults with English as a first language. This study sought to explore the relation between encoding modality (auditory, visual, or visual and auditory; based on Baddeley’s model of working memory) and rehearsal strategy (active or passive, based on Craik and Lockhart’s Level of Processing approach and Roger’s Self-Reference Effect) in the recall of foreign language vocabulary words. Vocabulary words were the target information …

Infants' Perception Of Faces In Face-Like And Ambiguous Images., Lauren E Dale

College of Arts & Sciences Senior Theses

Faces are special to infants. Infants look longer at faces than objects, human faces than non-human faces, and upright faces compared to inverted faces. The objective of this study was to see if infants demonstrated signs of pareidolia. Pareidolia is the ability to see a face in a non-face object, such as a face in a cloud. Previous research has shown that adults see faces in everyday objects, but less is known about infants' perception of such images. In the present study, infants 7-9 months old (N = 47) were tested. Infants were shown eight images, which adults had …

A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko

Senior Honors Projects

Sexual dimorphism is exhibited across all cricket species and is a central aspect of the mating processes of these insects. Only male crickets possess wing structures and pattern generators in the central nervous system that allow them to produce a mating call that is unique to their species in order to attract conspecific females. Conspecific females possess an auditory feature detection circuit in the central nervous system that is capable of detecting the species-specific frequency and temporal pattern of sound pulses within a male call. In order for dimorphic differences in mating behavior to result in successful continuation of a …

Does Personality Similarity In Bottlenose Dolphin Pairs Influence Dyadic Bond Characteristics?, Kelsey R. Moreno

Master's Theses

Social structures are critical to the success of many species and have repercussions on health, well-being, and adaptation, yet little is known about the factors which shape these structures aside from ecology and life history strategies. Dyadic bonds are the basis of all social structures; however, mechanisms for formations of specific bonds or patterns in which individuals form which types of bonds have yet to be demonstrated. There is a variety of evidence indicating personality may be a factor in shaping bonds, but this relationship has not been explored with respect to bond components and is yet to be demonstrated …

Do Pinnipeds Have Personality? Coding Harbor Seal (Phoca Vitulina) And California Sea Lion (Zalophus Californianus) Behavior Across Contexts, Amber J. De Vere

Master's Theses

Personality has now been studied in species as diverse as chimpanzees (King & Figueredo, 1997) and cuttlefish (Carere et al., 2015), but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only in the bottlenose dolphin (Highfilll & Kuczaj, 2007), while consistent individual differences in a few specific behaviors have been identified in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012). Furthermore, the context component of definitions of personality is not often assessed, despite evidence that animals may show …

Grooming As An Agonistic Behavior In Garnett’S Small-Eared Bushbaby (Otolemur Garnettii), Jennie L. Christopher

Master's Theses

Social behaviors are a necessary component of group living and interactions between organisms. To correctly assess social interactions, researchers must be able to observe behaviors and interpret their function based on the behavior or the behavioral context. In primate species, grooming is often used to assess affiliations between group members and the consensus has been to always interpret grooming as an affiliative behavior. However, a number of avian, rodent and feline species have been shown to groom conspecifics aggressively. These instances of aggressive grooming appear most often when individuals are required to maintain close proximity to one another, such as …

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan

Master's Theses

Sleep serves many vital functions in humans, ranging from energy restoration to memory consolidation and information integration. Sleep deprivation is linked to worsened physiological states and psychological conditions. Zebrafish are an emerging model in neurobehavioral research and have recently demonstrated great utility in the study of sleep. This teleost species possesses several of the same neurotransmitter and neuropeptide systems that are involved in the regulation of sleep and waking rhythms in higher order mammals. Previous study of these animals has revealed a differential gene and proteomic expression following sleep deprivation through changes in environmental stimuli. The present study sought to …

The Effect Of Boat Type On Bottlenose Dolphin (Tursiops Trucatus) Behavior In The Mississippi Sound, Maria Zapetis

Master's Theses

Increases in oceanic shipping are a global phenomenon, and a leading cause of concern for marine animal welfare. While it may be difficult to assess the effect of boat traffic on all species in all contexts, it is vital to report anthropogenic impacts where longitudinal data is available, and doubly so where a dearth of information exists. The purpose of this study is to describe how dolphin behavior changed in the presence of boats in the Mississippi Sound between 2006 and 2012, and more specifically, to detail how different boat types impacted dolphins’ behavioral states. This study is unique in …

Story Problem Solving, Brian D. Kalina

Creativity and Change Leadership Graduate Student Master's Projects

This project paper will explore and define the relationship between the Creative Problem Solving (CPS) and the timeless concept of storytelling. Since the beginning of time, people have been sharing stories to relate their experiences and their solutions to overcome challenges and obstacles. CPS is a more modern methodology that aids people in their approach and their ability to generate plans and solutions to overcome challenges and obstacles. Therefore, the premise of this project is to seek answers to the questions; (1) How might we look to stories as frameworks for solving our problems? and (2) How might we marry …

Subjective Expected Utility And Sexual Coercive Behaviors: Examining The Role Of Decision Processes, Alcohol Consumption, And Rape-Supportive Attitudes Among College Males, Antover P. Tuliao

Department of Psychology: Dissertations, Theses, and Student Research

Prior studies have established the role of rape-supportive attitudes and alcohol consumption in sexual coercive behaviors among college students. However, less research has examined the role of more proximal variables such as decision processes. Utilizing the subjective expected utility (SEU) model of decision making, this study aimed to examine how decisions are made in a date-rape scenario utilizing a vignette methodology. The SEU model posits that decisions to engage in a behavior are contingent on perceived utility of the action, perceived probability of the utility occurring, perceived cost of the behavior, and the perceived probability of the cost occurring. Higher …

A Study Of The Effects Of Methylene Blue, Scopolamine, And Stress On Learning And Memory In The Zebrafish, Erika Marie Caramillo

Dissertations

With the ever-increasing aging population, neurodegenerative diseases such as Alzheimer’s disease are becoming more prevalent. Owing to such increases in age related cognitive decline, the need for research into new, effective treatments is more imperative now than ever. The zebrafish is an excellent animal model that can be used to study the potential pharmacological effects of novel cognition-centric treatments. However, more needs to be known about the species and its ability to learn, remember, and the effects certain drugs have on behavior. In this dissertation, I aimed to better understand zebrafish cognition through the testing of three conditions: a known …

Anxiety-Like Behaviors And C-Fos Expression In Adult Zebrafish: Effects Of Housing Conditions, Alcohol And Caffeine, Adam Douglas Collier

Dissertations

Alcohol abuse is the third largest risk factor for disease world, responsible for an estimated 3.3 million deaths each year. The concomitant ingestion of alcohol and caffeine is hypothesized to increase risk factors associated with alcohol use alone by reducing subjective effects of intoxication. The zebrafish (Danio rerio) has recently garnered attention from researchers as an effective pre-clinical in-vivo animal model in behavioral pharmacology research, largely due to small size, low-cost and ease of drug delivery. A number of studies have reported the effects of alcohol and caffeine on zebrafish behavior at a variety of doses. However, the …

Pragmatic Understanding Of Bottlenose Dolphins (Tursiops Truncatus) Use Of A Two-Way Communication System, Pepper Reid Hanna

Dissertations

Pragmatics focuses on how a communication system is used to achieve a communicative goal, the social context of the communication, and the organizational structure of communications (Horn & Ward, 2004; McLaughlin, 1998). There is evidence of pragmatics within animal communication systems. For example, context appears to be an important component in both signal production and a receiver’s response in vervet monkeys (Seyfarth et al. 1980).

MA Thesis: http://aquila.usm.edu/masters_theses/170/

The current study used an underwater keyboard to establish a two-way communication system between humans and dolphins. The purpose of this study was to determine if, under these conditions, dolphins displayed pragmatic …

Efficacy Of Cognitive Enrichment For Bottlenose Dolphins (Tursiops Truncatus): Evaluation Of Planning Abilities Through The Use Of A Novel Problem Solving Task, Lisa Kay Lauderdale

Dissertations

Environmental enrichment is a key component to improving the psychological and physiological well being of animals in human care. Enrichment can be achieved through a variety of modalities, including the addition of objects and scents, or by providing the animals with additional challenges. The effectiveness of specific enrichment should be evaluated on a case-by-case basis to determine if the desired result is achieved. Environmental enrichment devices (EED’s) can be utilized to present novel problems to animals in human care. When confronted with a novel problem, dolphins can plan their behavior to create a more efficient strategy then previously modeled.

Behavioral Phenotypes Associated With Mptp Induction Of Partial Lesions In Common Marmosets (Callithrix Jacchus), Kimberley A. Phillips, C. N. Ross, J. Spross, C. J. Cheng, Alyssa Izquierdo, K. C. Biju, C. Chen, S. Li, S. D. Tardif

Psychology Faculty Research

Parkinson’s disease is a chronic neurodegenerative disorder with the core motor features of resting tremor, bradykinesia, rigidity, and postural instability. Non-motor symptoms also occur, and include cognitive dysfunction, mood disorders, anosmia (loss of smell), and REM sleep disturbances. As the development of medications and other therapies for treatment of non-motor symptoms is ongoing, it is essential to have animal models that aid in understanding the neural changes underlying non-motor PD symptoms and serve as a testing ground for potential therapeutics. We investigated several non-motor symptoms in 10 adult male marmosets using the MPTP model, with both the full (n …

And, The Winner Is…A Visual Preference For Endpoints Over Starting Points In Infants’ Motion Event Representations, Laura Lakusta, Stephanie Difabrizio

Department of Psychology Faculty Scholarship and Creative Works

Infants represent objects that are endpoints in motion events and show a preference for encoding the endpoint (the duck waddles into a bowl) over the starting point (the duck waddles out of a box). This asymmetry continues to appear in nonlinguistic cognition and language throughout development. This study tests whether this asymmetry also shows up in 16-month-old infants’ visual preferences for motion events, and if so, for which types of events. Infants looked longer at events depicting an “agentive” figure (e.g., duck) moving into an object (endpoint) than out of an object (starting point), and this asymmetry persisted even when …

Identifying Behavioral Response Trends Following Aggression In Bottlenose Dolphins (Tursiops Truncatus), Breanna M. Cheri

Honors Theses

In group-living species, an individual’s response to aggression from another animal can reveal information about the complexities of their social relationships. The current study sought to categorize behavioral responses between conspecifics following direct aggression. Agonistic behavioral interactions were analyzed in a semi-captive group of bottlenose dolphins housed at the Roatan Institute for Marine Sciences, whose population dynamics mirror those observed in the wild. Interactions began at the onset of an aggressive behavior, and all concomitant behaviors between aggressor(s) and recipient(s) were coded chronologically for the length of each event. Results revealed five response types present following aggression: retaliation, reconciliation, avoidance, …

Insightful Problem Solving And Emulation In Brown Capuchin Monkeys, E. Renner, Allison M. Abramo, M. K. Hambright, Kimberley A. Phillips

Psychology Faculty Research

We investigated problem solving abilities of capuchin monkeys via the "floating object problem," a task in which the subject must use creative problem solving to retrieve a favored food item from the bottom of a clear tube. Some great apes have solved this problem by adding water to raise the object to a level at which it can be easily grabbed. We presented seven capuchins with the task over eight trials (four "dry" and four "wet"). None of the subjects solved the task, indicating that no capuchin demonstrated insightful problem solving under these experimental conditions. We then investigated whether capuchins …

Extension Of Behavioral Momentum Theory To Conditions With Changing Reinforcer Rates, Andrew R. Craig

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavior is more likely to persist when disrupted in some way in the presence of stimuli correlated with frequent delivery of reward than in the presence of stimuli correlated with infrequent rewards. In laboratory investigations, the correlation between reward rates and specific stimuli are almost always held constant before testing for persistence. In the real world, however, how often rewards are encountered is likely to vary substantially over time. The major goal of the work described in this dissertation was to explore effects of reward rates that change over time on persistence of behavior in controlled laboratory settings using pigeon …
