Effects Of Brief-Signal Number And Location On Responding Maintained By Delay Of Reinforcement, Firdavs Khaydarov
Graduate Theses, Dissertations, and Problem Reports (ETD)
The purpose of the present series of experiments was to examine the effects of the number, type, and location of brief signal(s) occurring during, but not throughout, a delay period, on responding maintained by the delay of reinforcement. In each experiment, a tandem variable time (VT) 60-s fixed interval (FI) 9-s schedule was used as a baseline condition of an immediate reinforcement against which delay conditions were examined. For the delay conditions, a chained variable interval (VI) 60-s fixed time (FT) 9-s (delay period) schedule was used, and the imposition of the brief signal (blackout) during the delay period was …

Effects Of Ethanol And Nicotine Co-Administration On Risky Choice In Rats, Erin E. Wylie
Graduate Theses, Dissertations, and Problem Reports (ETD)
Individuals often engage in the comorbid use of alcohol (ethanol) and nicotine, leading to further-escalated health consequences than the use of either drug in isolation. Given the poor health outcomes resulting from the combined administration of ethanol and nicotine, some of which may be due to increased risky choice, more basic research is needed to better characterize drug/dose interactions on risky choice. Probability-discounting procedures involve a series of discrete choices between a smaller, certain reinforcer (i.e., a safer choice) and a larger, increasingly uncertain reinforcer (i.e., a riskier choice). Probability-discounting procedures allow for the assessment of …

Response Maintenance By Mediated Reinforcement With Forced Alternation Of Reinforcement Opportunities, Kento Yasukawa
Graduate Theses, Dissertations, and Problem Reports (ETD)
Three experiments were conducted to investigate the effects of mediated reinforcement –reinforcers delivered to either of two co-actors by the responses of the other co-actor, but independently of the responses of the co-actor receiving the reinforcer– on the maintenance of responding of the co-actors. In each experiment, using a discrete-trials procedure, responding and receiving reinforcers alternated between co-actors. In Experiment 1, the alternation followed each reinforcer. Also investigated in this experiment were the effects of the presence and absence of social stimuli and of the role of reinforcement delays on individual responding. The number of consecutive reinforcer deliveries to either …
Intermittent Sucrose Access: Sweetness Versus Calories,

Intermittent Sucrose Access: Sweetness Versus Calories, Jarret Folmer, Rudy Eikelboom
Theses and Dissertations (Comprehensive)
Nondeprived rats receiving every 3rd day access (E3DA) to 4% sucrose solution consume more sucrose on access days compared to rats with everyday access (EDA). Rats receiving EDA or E3DA to 16% sucrose do not consume different amounts, but if placed on every 2nd day access (E2DA) to 4% sucrose E3DA-group rats consume more than EDA rats (Eikelboom, Hewitt, & Adams, 2022). E3DA affects rats’ value of sucrose but effects appear hidden with high sucrose concentrations. Valyear and Eikelboom (2021) suggested that calorie ceilings limit E3DA-induced consumption with high sucrose, but this ceiling could also be caused by …
Psychosocial Factors And E-Cigarette Use: An Application Of Problem Behavior Theory,

Psychosocial Factors And E-Cigarette Use: An Application Of Problem Behavior Theory, Samantha A. Fitzer
Psychology Theses & Dissertations
Electronic cigarette (e-cigarette) use has increased among the U.S. population in recent years with estimates showing that nearly 15% of American adults have tried an e-cigarette (Villarroel et al., 2020). Problem Behavior Theory (PBT) has successfully outlined a variety of factors that affect an individual’s engagement in an identified problem behavior. In an attempt to better understand e-cigarette use among an emerging adult population (i.e., college student population), the purpose of the current study was to explore how a large subset of PBT factors may differentiate between e-cigarette user categories (nonuser, non-daily user, daily user). A sample of 487 college …

Research Collection School of Social Sciences
Responses to COVID-19 public health interventions have been lukewarm. For example, only 64% of the US population has received at least two vaccinations. Because most public health interventions require people to behave in ways that are evolutionarily novel, evolutionary psychological theory and research on mismatch theory, the behavioral immune system, and individual differences can help us gain a better understanding of how people respond to public health information. Primary sources of threat information during the pandemic (particularly in early phases) were geographic differences in morbidity and mortality statistics. We argue that people are unlikely to respond to this type of …

An Investigation Of Lab-Based Research Procedural Fidelity: The Relationship Between Experimenter Infant-Directed Speech, Temperament And Language Proficiency, Tess A. Simpson
Electronic Theses and Dissertations
The purpose of the present study was to investigate whether developmental researchers were influenced in the laboratory by the characteristics of children who participate in their research. I hypothesized that experimenters, as social partners, would adapt their speaking and other behaviors to the child’s perceived temperamental profile and language proficiency. I specifically focused on whether experimenters would adhere to the experimental laboratory procedure of two elicited imitation tasks, Feed Bear and Make a Rattle, in an archival dataset. Participants included 61 primarily white 15-month-olds. Coders transcribed infant directed speech (IDS) and analyzed transcriptions for total words, words per sentence, and …

Toxic Effect Of Fear Of Losing Out On Self-Esteem: A Moderated Mediation Model Of Conformity And Need For Cognitive Closure In Singapore, Sheila Xi Rui Wee, Chi-Ying Cheng, Haelim Choi, Ciping Goh
Research Collection School of Social Sciences
Kiasu (fear of losing out, FoLO) is considered the single most defining adjective that captures Singapore identity, and it is well-observed in other Asian cultures as well. Despite the widespread endorsement of kiasu in Singapore, there is limited empirical research on the theoretical conception of kiasu as a psychological construct. To empirically investigate kiasu, we validated the construct and measurement of the FoLO mindset in Study 1. In Study 2, we hypothesized and found a negative association between FoLO and Singaporeans’ self-esteem, which was mediated by a higher tendency of conformity. In addition, we hypothesized and found that individuals’ need …

K-5 Elementary Alternative Program: A Case Study, William E. Scheuer Iv
Electronic Theses and Dissertations
The purpose of this case study was to examine how the K-5 elementary alternative program All Students Can Thrive (ASCT) used student-centered learning practices to influence the whole child. There is a lack of research on K-5 elementary alternative programs, such as ASCT, and specifically those that integrate student-centered learning practices to influence the whole child. Literature does not contain universally accepted interventions that are effective in the elementary alternative setting to help students return to the mainstream classroom setting better prepared to display appropriate behaviors when a student is removed from a mainstream classroom setting due to disruptive behaviors. …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan
Dissertations
This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Impact Of Adolescent Social Isolation On Adult, Binge-Like Ethanol Consumption And Plasma Corticosterone In High-Alcohol-Preferring Mice, Eva Cullins
The Journal of Purdue Undergraduate Research
Adolescent stress exposure increases the likelihood of alcohol misuse and alcohol use disorder (AUD) in adulthood; however, it is not clear how genetic and environmental factors interact to increase risk. This study examined how adolescent social isolation affects adult binge-like ethanol drinking and levels of the stress hormone corticosterone in male and female mice with a genetic predisposition toward high alcohol preference (HAP). Twenty-eight HAP mice were separated into group-housed (GH) and socially isolated (SI) conditions (n = 13, 13). Binge drinking was assessed using a drinking in the dark (DID) procedure. Blood samples were taken before DID and after …

Does Trait Self-Esteem Serve As A Resilience Factor In Maintaining Affective Well-Being? Findings From Daily Diary Studies In Singapore And The United States, Matthew H. S. Ng, Verity Yu Qing Lua, Nadyanna M. Majeed, Andree Hartanto
Research Collection School of Social Sciences
Research suggests that self-esteem could be a protective factor in stressful or unfavorable situations. However, little research has been done on the buffering role of self-esteem in the context of daily stressors on affective reactivity. Three daily diary studies (of which two were conducted in Singapore and one in the United States) were carried out to examine this relationship. In all three studies, trait self-esteem was measured at baseline. Subsequently, daily assessment was conducted on exposure to daily stressors, and positive and negative affect for seven to eight days. Multilevel modeling showed that trait self-esteem did not moderate the relationship …

Event-Related Potentials Of Individuals With Attention-Deficit/Hyperactivity Disorder Performing The Attention Network Task, P. Dennis Rodriguez, Justin E. Stauffacher
Midwest Social Sciences Journal
The current study sought to investigate the neural basis of attention-deficit/hyperactivity disorder (ADHD) by examining the performance of individuals with ADHD on the Attentional Networks Test (ANT) by Fan, McCandliss, Sommer, Raz, and Posner (2002), while recording electroencephalography (EEG) utilizing event-related potentials (ERP) methodology. Fifty-seven university students were divided into three groups: control, ADHD-inattentive subtype (ADHD-IA), and ADHD-combined/hyperactive impulsive subtype (ADHD-C/HI). The average peak amplitudes of the P300 waveform for each group were compared and analyzed for performance on each attention network measured by the ANT: the alerting network, the orienting network, and the executive control network. The average P3 …

International Conference on Assessment and Learning (ICAL)
The COVID-19 pandemic has been going on for more than two years and has caused problems for the world community. One of the impacts of COVID-19 is psychological barriers, including decreased well-being, increased stress, anxiety, depression, loss of family members, and being laid off. Is there still energy in a difficult situation like this to give empathy and have a sense of wanting to help without reward (altruism)? The psychological condition of the impact of COVID-19 is the background for the need to carry out valid and reliable psychological measurements. This study aims to identify the psychometric properties of three …

Self-stigma is an important factor that hinders help seeking through the use of mental health services. “Self-stigma is the reduction of an individual’s self-esteem or self-worth caused by the individual self-labeling herself or himself as someone who is socially unacceptable” (Vogel et al., 2006, p. 325). Attitudes have suggested both men and women struggle with depression in this population, and that they are reluctant to addressing psychological problems. Most are overly concerned about the stigma associated with mental illness. Though some are open to seeking treatment through mental health services, religious coping in this community is the most preferred method …

The Differential Effects Of Acoustic Discriminations On Operant Learning Performance And Neurogenesis In Male And Female Zebra Finches, Kristena L. Newman
Dissertations, Theses, and Capstone Projects
Adult neurogenesis, the creation of new neurons, occurs throughout the lifespan in most organisms. However, though neuronal proliferation occurs daily, most of these neurons do not survive to become incorporated into preexisting neural circuitry and become fully functioning neurons. In the mammalian brain, adult neurogenesis occurs within the hippocampus, a brain region known to be important in learning and memory. In rats, successful acquisition of certain learning tasks increased new neuron numbers when the learning was sufficiently challenging (Curlik and Shors, 2011). It has also been demonstrated that a spatial discrimination task requires new neurons when the discrimination is more …

In Covid-19 Health Messaging, Loss Framing Increases Anxiety With Little-To-No Concomitant Benefits: Experimental Evidence From 84 Countries, Charles A. Dorison, Et. Al., Andree Hartanto
Research Collection School of Social Sciences
The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g., “If you do not practice these steps, you can endanger yourself and others”) or potential gains (e.g., “If you practice these steps, you can protect yourself and others”)? Collecting data in 48 languages from 15,929 participants in 84 countries, we experimentally tested the effects of message …

Examining The Impact Of Financial Stress On Affect And Eating Behaviors, Ellen Hunt Steele
Theses and Dissertations
Economic pressure and concomitant financial stress have been associated with mental and physical health problems, conflict, and poorer education and employment outcomes. Moreover, financial stress can be seen in specific hardships (e.g., food insecurity) and lead to maladaptive attempts to regulate emotions stemming from financial stressors. Women may be more vulnerable to consequences of food insecurity and attempts to regulate emotions with eating than men. Thus, the current study examined the impact of a randomized financial stress induction on affect and snack food choice while accounting for the influence of food insecurity and gender. Participants included 269 validly responding individuals. …

The Effects Of Flood Warning Information On Driver Decisions In A Driving Simulator Scenario, Katherine Rose Garcia
Psychology Theses & Dissertations
Flood warnings are a type of risk communication that alerts the public of potential floods. Flood warnings can be communicated through mobile devices and should convey enough information to keep the user safe during a flood situation. However, the amount of detail included in the warning, such as the depth of the flood, may vary. The purpose of this study was to: (a) extend our prior research on flood warnings by recreating the written driving scenarios into the driving simulator; (b) deepen the understanding of human decision-making in risky situations; and (c) investigate how to best inform drivers of floods …
