The Effects Of Escalated Fentanyl Intake On Decision-Making Dynamics, Trinity Shaver Jan 2023

The Effects Of Escalated Fentanyl Intake On Decision-Making Dynamics, Trinity Shaver

Theses and Dissertations--Psychology

Opioid Use Disorder is characterized partially as a decision-making disorder. Decision-making theories, such as habit theory and relative value theory, have aimed to better understand the shift in preference for drug over other alternatives. In order to compare these two contrasting theories, an allomorphic concurrent choice task will run in tandem with an escalation procedure. Male and female Sprague-Dawley rats were tested for choice differences in an allomorphic choice procedure. Reward dimensions, such as relative reward rate, were manipulated within sessions, and magnitude (remifentanil dose), was manipulated between sessions. To study the effects of escalated fentanyl intake on relative valuation, …

Effects Of Social Isolation And Adolescent Ethanol Exposure On Adult Drinking And Nicotine Co-Use, Jakob Shaykin Jan 2023

Effects Of Social Isolation And Adolescent Ethanol Exposure On Adult Drinking And Nicotine Co-Use, Jakob Shaykin

Theses and Dissertations--Psychology

Alcohol use often begins in adolescence and can lead to increased susceptibility to AUD in adulthood. Stress in the form of social isolation during adolescence can also prompt substance use disorders later in adulthood. This thesis determined if exposure to ethanol (EtOH) during adolescence and social isolation alters the trajectory of alcohol and nicotine intake during adulthood. In Experiment 1, adolescent male and female Sprague-Dawley rats were administered intermittent injections of EtOH (2g/kg 20% EtOH, IP) or saline (PND 28-41). EtOH consumption was measured in adulthood (PND 49-55) using a 2-bottle choice procedure where one bottle contained a 0.2% saccharin/15% …

The Effects Of Social And Nonsocial Contextual Stimuli On The Renewal Of Cocaine Seeking, Bree Humburg Jan 2023

The Effects Of Social And Nonsocial Contextual Stimuli On The Renewal Of Cocaine Seeking, Bree Humburg

Theses and Dissertations--Psychology

Those with substance use disorders can undergo craving and relapse when re-exposed to a drug-associated context. This study determined if renewal of cocaine seeking is differentially controlled by contexts consisting of social and/or nonsocial stimuli. Experiment 1, rats self-administered cocaine in Context A which included a social peer and house light illumination. Following self-administration, rats were randomly assigned to an AAA or ABA group for extinction and renewal. For the AAA rats, context was similar to self-administration; for ABA rats, the drug-associated stimuli (peer and house light) were removed (Context B). Following extinction, renewal of cocaine seeking was examined by …

Intermittent Sucrose Access: Sweetness Versus Calories, Jarret Folmer, Rudy Eikelboom Jan 2023

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, Samantha A. Fitzer Dec 2022

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 …

Responses To Covid-19 Threats: An Evolutionary Psychological Analysis., Stephen M. Colarelli, Tyler J. Mirando, Kyunghee Han, Norman P. Li, Carter Vespi, Katherine A. Klein, Charles P. Fales Dec 2022

Responses To Covid-19 Threats: An Evolutionary Psychological Analysis., Stephen M. Colarelli, Tyler J. Mirando, Kyunghee Han, Norman P. Li, Carter Vespi, Katherine A. Klein, Charles P. Fales

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 Dec 2022

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 Dec 2022

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 Dec 2022

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 Nov 2022

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 Nov 2022

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 Nov 2022

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 Oct 2022

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 …

Adaptation Of Three Psychological Measurement Instruments Assessing The Impact Of The Covid-19 Pandemic: Fear Of Covid-19 Scale, Coronavirus Anxiety Scale, And Altruism, Angela Oktavia Suryani, Laura Fransisca Sudarnoto, Benedicta Prihatin D. Riyanti

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 …

Evaluating The Stigma Toward Counseling In The African American Community, Jamaica Chapman Oct 2022

Evaluating The Stigma Toward Counseling In The African American Community, Jamaica Chapman

Doctoral Projects

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 Sep 2022

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 Sep 2022

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 Aug 2022

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 Aug 2022

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 …

Hurting To Helping: Regret As A Potential Motivator Of Helping Behavior, Chandler Ann Findley Aug 2022

Hurting To Helping: Regret As A Potential Motivator Of Helping Behavior, Chandler Ann Findley

Graduate Theses and Dissertations

Previous research has suggested that emotions can influence people’s motivation to engage in prosocial behaviors. Even negatively-valenced emotions, like sadness, guilt, and shame, have been shown to motivate prosocial behaviors. Exploratory analyses of a previous study indicated that regret may also motivate increased prosocial intentions, but no research has been published to experimentally test whether feelings of regret may motivate prosocial behaviors. Therefore, the present research seeks to experimentally manipulate participants’ current emotional state to empirically examine whether regret motivates greater helping behavior than other, similar negative emotions that have already been demonstrated to motivate prosocial behaviors in humans. These …

Selfies And The Self: The Influence Of Instagram Posting On Self And Cognition, Giovanni Castillo Jul 2022

Selfies And The Self: The Influence Of Instagram Posting On Self And Cognition, Giovanni Castillo

Theses

Research on Social Networking Sites (SNS) has shown a variety of both beneficial and detrimental psychological and cognitive outcomes associated with high frequency usage. We conducted an online study consisting of a series of questionnaires and a working memory task to explore the relationship between Instagram use intensity and cognition. The present study first investigated the relationship between Instagram (IG) use intensity, rumination, and cognitive failures. We randomly assigned participants into a selfie-posting, selfie-sending, or likes/comments reporting condition to determine whether selfie-posting behavior affects working memory performance. While we did not find significant associations between IG use intensity, rumination, and …

Mementos And The Endowment Effect, Charlene K. Chu, Suzanne B. Shu Jul 2022

Mementos And The Endowment Effect, Charlene K. Chu, Suzanne B. Shu

Business Faculty Articles and Research

This research provides evidence for a new moderator of the endowment effect: having a memento of the endowed object. Three studies adapting classic endowment effect paradigms and using a variety of endowment objects and mementos demonstrate that having a memento of an endowment increases willingness to trade the endowment and decreases selling prices for the endowment. We provide evidence that mementos attenuate the endowment effect regardless of whether the memento is a separate small gain when facing the loss of the endowment or a small part of the original endowment that is kept. Examining mementos in context of the endowment …

The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee Jul 2022

The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee

Theses

As seen in decades of psychology research, preferences play a major role in driving the decision-making process in both humans and animals. Researchers have advocated for using the technique of experimental evolution as a way to address some of the foundational questions on preferences. These preferences can also affect what is later learned and how well new experiences are learned. Salience is usually mentioned as an important component of what could influence preferences. Animals such as Drosophila melanogaster, that lay eggs without any additional maternal or paternal care, it is important to be selective when deciding where to lay …

Simulated Owl Predation During Foraging Differentially Alters Choice And Fear Behavior Between Sex In Rats, Meghan M. Olsen Jul 2022

Simulated Owl Predation During Foraging Differentially Alters Choice And Fear Behavior Between Sex In Rats, Meghan M. Olsen

Research Psychology Theses

Existing research on the predator cue circuit has indicated there are observed differences between sexes of animals either directly or indirectly exposed to a predator stimulus. Exposure increases predator directed attention, and overrides other motivational systems (hunger, pain, reproductive behavior). Little research has explored whether exposure to predation is associated with differential responses to non-predator related decision-making across a variety of tasks. Therefore, understanding the prioritization of motivational states when a predator stressor is present can aid in understanding sex differences in these processes in both adaptative and maladaptive conditions. To determine how repeated exposure to a predator stressor differentially …

The Influence Of Parental Psychological Control On Offspring Anxiety Symptomatology: A Cognitive Model, Yu Ping Wong Jul 2022

The Influence Of Parental Psychological Control On Offspring Anxiety Symptomatology: A Cognitive Model, Yu Ping Wong

Dissertations and Theses Collection (Open Access)

Parental control has often been purported to be a risk factor for offspring anxiety. Recent studies however, identify that a particular dimension of control - parental psychological control - is an especially important contributor to anxiety. However, the mechanisms behind this relationship remain unknown. Thus, in this study, we seek to bridge this gap in the literature by examining whether a cognitive mechanism underlies this relationship. Drawing on Beck's model of emotional disorders, we propose that control- related beliefs and negative automatic thoughts would serially mediate the influence of psychological control on anxiety symptoms. Moreover, we sought to examine the …

Cognitive Consequences Of Covid-19 Infection And Quarantine-Induced Social Isolation: Hope For The Young And Mildly Infected, Kristin Nickole Kirchner Jul 2022

Cognitive Consequences Of Covid-19 Infection And Quarantine-Induced Social Isolation: Hope For The Young And Mildly Infected, Kristin Nickole Kirchner

Theses and Dissertations

Coronavirus disease 2019 (COVID-19) has infected over 539 million individuals worldwide, and initial research supports the possibility that COVID-19 may damage the central nervous system either directly or indirectly. Neurological signs and noted cognitive deficits observed in even mildly infected patients are a cause for concern for those infected by COVID-19; the effect of social isolation on the central nervous system is also of interest. The present study sought to determine the extent of these potential cognitive deficits in a young and mildly infected sample of college students. Participants completed an extensive survey assessing their experience with COVID-19 and any …

Sex Differences In Locomotor Activity And Behavioral Sensitization In Rats Administered Fentanyl, Jessica J. Lee, Nareen Sadik, Cameron Davidson Phd, Majd Yahya, Josie Zdun, Shane Perrine Phd

Medical Student Research Symposium

Opioid overdoses have continued to increase, and women have experienced a greater rate of increase than males. Preclinical studies demonstrate marked sex differences in addiction-related behaviors, with females being more vulnerable due to a potential role of estradiol. We sought to understand how the estrous cycle, as a proxy measure of estradiol, influences sex differences in the sensitizing effects of fentanyl. In this ongoing study, we used male and female rats to investigate potential sex effects of fentanyl (20µg/kg subcutaneously) administration for 14 days and a forced abstinence period of 13 days on behavioral sensitization via locomotor activity (LMA) following …

Comparing Crime Scene Trajectories: Sexual Versus Nonsexual Serial Homicides, Jonathan T. Dixon Jun 2022

Comparing Crime Scene Trajectories: Sexual Versus Nonsexual Serial Homicides, Jonathan T. Dixon

Student Theses

When faced with a possible serial offender, crime linkage analysis is crucial in identifying which crime scenes belong to the same offender. Thus, when analyzing behavioral consistency to link crimes, it is essential to use a classification model that is empirically tested and is based on the type of crime being investigated. Several classification models examine patterns of consistency and change using a combination of thematic and behavioral subgroups; however, they are tested using sexual and nonsexual crime scenes, which some recent literature argues are two distinct types of homicide and should be examined separately. The present study tests the …
