A Comparison Of Adult Black And White Male Killers' Behaviors, Their Motives For Murder, And What They Do With Their Victims' Bodies, Tracy Sargent
A Comparison Of Adult Black And White Male Killers' Behaviors, Their Motives For Murder, And What They Do With Their Victims' Bodies, Tracy Sargent
Doctoral Dissertations and Projects
Studies involving murder are often focused on one offender group or a specific victim type. Due to focused research on this topic, there is a need to explore homicidal research between two offender groups in order to compare deviant behaviors of persons who commit murder. The comparison of adult black male offenders and adult white male offenders, their motivations for murder, and what offenders do with their victims’ bodies is explored in the study. A total of 300 solved homicide cases, which consists primarily of adult male and female victims, and several child murders was collected. Such murder motivations of …

BACKGROUND: Alzheimer's disease (AD) is notably associated with cognitive decline resulting from impaired function of hippocampal and cortical areas; however, several other domains and corresponding brain regions are affected. One such brain region is the hypothalamus, shown to atrophy and develop amyloid and tau pathology in AD patients. The hypothalamus controls several functions necessary for survival, including energy and glucose homeostasis. Changes in appetite and body weight are common in AD, often seen several years prior to the onset of cognitive symptoms. Therefore, altered metabolic processes may serve as a biomarker for AD, as well as a target for treatment, …

Journal Articles
OBJECTIVES: Examine acculturation and psychological, lifestyle, and physiological factors based on gender and country of origin (U.S. vs. Mexico).
METHODS: Baseline data from the Starr County diabetes prevention study (
RESULTS: Participants were: predominantly female (73%); 51 years of age, on average; born in Mexico (71%); and Spanish-speaking. Individuals spent 11 of their waking hours (range = 0-18 h) in sedentary activities. Compared to females, more males spoke English and reported fewer hours in sedentary activities. Compared to participants born in Mexico, those born in the U.S. were more likely to: speak English; report depressive symptoms; and exhibit elevated BMI …

Explicit recognition measures of statistical learning (SL) suggest that children and adults have similar linguistic SL abilities. However, explicit tasks recruit additional cognitive processes that are not directly relevant for SL and may thus underestimate children's true SL capacities. In contrast, implicit tasks and neural measures of SL should be less influenced by explicit, higher-level cognitive abilities and thus may be better suited to capturing developmental differences in SL. Here, we assessed SL to six minutes of an artificial language in English-speaking children (n = 56, 24 females, M = 9.98 years) and adults (n = 44; 31 females, M …

Psychology Faculty Publications
Nearly all past research about body dissatisfaction and romantic relationship factors is among heterosexual couples; little is known about these associations in sexual minority couples. The present study aimed to fill gaps in the current literature by using actor-partner interdependence models (APIMs) to examine dyadic patterns of association between body dissatisfaction and different aspects of relationship functioning among same-sex female couples. Participants were 163 same-sex female romantic dyads (326 women) between the ages of 18-35 years who completed measures of body dissatisfaction and relationship factors. Results from significance testing of actor and partner effects indicated higher levels of women's own …
Exploration Of Height Dissatisfaction, Muscle Dissatisfaction, Body Ideals, And Eating Disorder Symptoms In Men, Daniel Talbot, Justin Mahlberg
Exploration Of Height Dissatisfaction, Muscle Dissatisfaction, Body Ideals, And Eating Disorder Symptoms In Men, Daniel Talbot, Justin Mahlberg
Sciences Papers and Journal Articles
Objective: Height is a significant, yet under-studied dimension of body dissatisfaction in men. The present study examined the relationship between height dissatisfaction, height, muscle and fat dissatisfaction, body ideals, and eating disorder symptoms in men.
Participants and methods: Participants were a sample of male undergraduate Australian students (N = 224) who were administered self-report measures of height, muscle, and fat dissatisfaction, eating disorder symptoms, and muscle and body fat body-ideals, and reported their height.
Results: Results showed that height, muscle dissatisfaction, and desired muscularity were important for explaining height dissatisfaction. Additionally, although eating disorder symptoms did not uniquely predict …

Psychology Faculty Publications
The purpose of this study was to understand the trajectories of nonsuicidal self-injury (NSSI) and suicide plans (SP) in the 90 days prior to inpatient hospitalization, understand the role of NSSI and SP in predicting suicide attempts (SA) on a given day, and to test the interaction between NSSI and SP in predicting same-day SA. Participants included 69 adolescents (77% female, 65% white, 77% Non-Hispanic/Latinx, Mage = 15.77 SDage = 1.00) from an inpatient psychiatric unit. Past 90 day NSSI, SP, and SA were measured using the Columbia Suicide Severity Rating Scale and Timeline Follow Back. First, mixed effect models …
Male Figural Rating Scales: A Critical Review Of The Literature, Daniel Talbot, John Cass, Evelyn Smith
Male Figural Rating Scales: A Critical Review Of The Literature, Daniel Talbot, John Cass, Evelyn Smith
Sciences Papers and Journal Articles
Figural rating scales are tools used to measure male body dissatisfaction. The present review aimed to examine the design and psychometric properties of male figural rating scales and make recommendations based on findings. Relevant databases were systematically searched for studies that had developed and validated male figural rating scales. Twenty studies were included in this review. Figural rating scales differed in terms of the number of images represented and type of stimuli used (hand-drawn silhouettes, hand-drawn figures, computer-rendered figures, and photograph figures). Reliability and validity evidence varied greatly in strength across all scales. Four of the 20 scales included a …

Psychology Publications
BACKGROUND: Although cognitive-behavioural therapy (CBT) is a well-established treatment for adult depression, its efficacy and efficiency may be enhanced by better understanding its mechanism(s) of action. According to the theoretical model of CBT, symptom improvement occurs via reductions in maladaptive cognition. However, previous research has not established clear evidence for this cognitive mediation model.
METHODS: The present study investigated the cognitive mediation model of CBT in the context of a randomized controlled trial of CBT v. antidepressant medication (ADM) for adult depression. Participants with major depressive disorder were randomized to receive 16 weeks of CBT (n = 54) or ADM …

Psychology Faculty Publications
This paper examines network prominence in a co-prescription network as an indicator of opioid doctor shopping (i.e., fraudulent solicitation of opioids from multiple prescribers). Using longitudinal data from a large commercially insured population, we construct a network where a tie between patients is weighted by the number of shared opioid prescribers. Given prior research suggesting that doctor shopping may be a social process, we hypothesize that active doctor shoppers will occupy central structural positions in this network. We show that network prominence, operationalized using PageRank, is associated with more opioid prescriptions, higher predicted risk for dangerous morphine dosage, opioid overdose, …

Socioemotional Selectivity And Psychological Health In Amyotrophic Lateral Sclerosis Patients And Caregivers: A Longitudinal, Dyadic Analysis, Suzanne C. Segerstrom, Edward J. Kasarskis, David W. Fardo, Philip M. Westgate
Psychology Faculty Publications
Objective: Socioemotional selectivity theory predicts that as the end of life approaches, goals and resources that provide immediate, hedonic reward become more important than those that provide delayed rewards. This study tested whether these goal domains differentially affected psychological health in the context of marital dyads in which one partner had been diagnosed with amyotrophic lateral sclerosis (ALS), a life-limiting disease.
Design: ALS patients (N = 102) being treated in three multidisciplinary clinics and their spouses (N = 100) reported their loneliness, financial worry and psychological health every 3 months for up to 18 months.

The Role Of Outcome Expectancy In Therapeutic Change Across Psychotherapy Versus Pharmacotherapy For Depression., Thulasi Thiruchselvam, David J A Dozois, R Michael Bagby, Daniela S S Lobo, Lakshmi N Ravindran, Lena C Quilty
Psychology Publications
BACKGROUND: Patient outcome expectancy - the belief that treatment will lead to an improvement in symptoms - is linked to favourable therapeutic outcomes in major depressive disorder (MDD). The present study extends this literature by investigating the temporal dynamics of expectancy, and by exploring whether expectancy during treatment is linked to differential outcomes across treatment modalities, for both optimistic versus pessimistic expectancy.
METHODS: A total of 104 patients with MDD were randomized to receive either cognitive behavioral therapy (CBT) or pharmacotherapy for 16 weeks. Outcome expectancy was measured throughout treatment using the Depression Change Expectancy Scale (DCES). Depression severity was …

AIMS: The Hamilton Depression Rating Scale (HAMD) and the Beck Depression Inventory (BDI) are the most frequently used observer-rated and self-report scales of depression, respectively. It is important to know what a given total score or a change score from baseline on one scale means in relation to the other scale.
METHODS: We obtained individual participant data from the randomised controlled trials of psychological and pharmacological treatments for major depressive disorders. We then identified corresponding scores of the HAMD and the BDI (369 patients from seven trials) or the BDI-II (683 patients from another seven trials) using the equipercentile linking …
The Art Of Seduction: Male Perceptions Of Sexual Willingness, Lisa Starrett
The Art Of Seduction: Male Perceptions Of Sexual Willingness, Lisa Starrett
Research on Capitol Hill
The United States continues to have the highest sexual assault rates of any developed nation.
The vast majority of sexual assault research studies exclusively female survivors. This overlooks half of the nation’s population. To find holistic solutions, we must address both genders.
The current study addresses:
- The male experience
Recent research shows significant numbers of men react with shock, guilt, shame, and depression when confronted with sexual assault charges. This opens questions of intent. - Confirmation bias & “echo chambers”
Social media and preference tracking amplify our tendency to see information that confirms our existing worldview. This further separates genders. - Environmental …

Cognition And The Brain Of Brood Parasitic Cowbirds., David F Sherry, Mélanie F Guigueno
Psychology Publications
Cowbirds are brood parasites. Females lay their eggs in the nests of other species, which then incubate the cowbird eggs and raise the young cowbirds. Finding and returning to heterospecific nests presents cowbirds with several cognitive challenges. In some species, such as brown-headed cowbirds (Molothrus ater), females but not males search for and remember the locations of potential host nests. We describe recent research on sex differences in cognition and the hippocampus associated with this sex difference in search for host nests. Female brown-headed cowbirds perform better than males on some, but not all, tests of spatial memory and females …

College of Education Faculty Research and Publications
Experiences of prejudice, discrimination, internalized homonegativity, and poor social support contribute to an increased risk for psychosocial distress among sexual minority individuals (King et al., 2008; Meyer, 2003). While much is known about factors predicting psychosocial distress in LGB populations, less is known about the factors that predict psychosocial well-being among bisexuals. The present study used structural equation modeling to investigate the effect that minority stress processes (e.g., discrimination, internalized homonegativity) have on positive psychosocial health outcomes (e.g., positive affect, meaning in life) in bisexual men. Additionally, the study’s model examined how positive sexual identity factors and universal protective factors …

OBJECTIVE: To determine whether self-reports of disaster-related psychological distress predict older adults' health care utilization during the year after Hurricane Sandy, which hit New Jersey on October 29, 2012.
METHODS: Respondents were from the ORANJ BOWL Study, a random-digit dialed sample from New Jersey recruited from 2006 to 2008. Medicare hospital, emergency department (ED) and outpatient claims data from 2012 and 2013 were matched to 1607 people age 65 and older in 2012 who responded to follow-up surveys conducted from July 2013 to July 2015 to determine their hurricane-related experiences.
RESULTS: In total, 7% (107) of respondents reported they experienced …

Priddis, Karl-Heinz Brisch, Collaboration On Attachment Transmission Synthesis
Research outputs 2014 to 2021
Parents' attachment representations and child-parent attachment have been shown to be associated, but these associations vary across populations (Verhage et al., 2016). The current study examined whether ecological factors may explain variability in the strength of intergenerational transmission of attachment, using individual participant data (IPD) meta-analysis. Analyses on 4,396 parent-child dyads (58 studies, child age 11-96 months) revealed a combined effect size of r = .29. IPD meta-analyses revealed that effect sizes for the transmission of autonomous-secure representations to secure attachments were weaker under risk conditions and weaker in adolescent parent-child dyads, whereas transmission was stronger for older children. Findings …

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall
Psychology Faculty Publications
Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …

Brain and Mind Institute Researchers' Publications
Following the loss of a sensory modality, such as deafness or blindness, crossmodal plasticity is commonly identified in regions of the cerebrum that normally process the deprived modality. It has been hypothesized that significant changes in the patterns of cortical afferent and efferent projections may underlie these functional crossmodal changes. However, studies of thalamocortical and corticocortical connections have refuted this hypothesis, instead revealing a profound resilience of cortical afferent projections following deafness and blindness. This report is the first study of cortical outputs following sensory deprivation, characterizing cortical projections to the superior colliculus in mature cats (

Atypical sensory perception is one of the most ubiquitous symptoms of autism, including a tendency towards a local-processing bias. We investigated whether local-processing biases were associated with global-processing impairments on a global/local attentional-scope paradigm in conjunction with a composite-face task. Behavioural results were related to individuals' levels of autistic traits, specifically the Attention to Detail subscale of the Autism Quotient, and the Sensory Profile Questionnaire. Individuals showing high rates of Attention to Detail were more susceptible to global attentional-scope manipulations, suggesting that local-processing biases associated with Attention to Detail do not come at the cost of a global-processing deficit, but …

BACKGROUND: Optimizing early nutritional intake in preterm neonates may promote brain health and neurodevelopment through enhanced brain maturation. Our objectives were (1) to determine the association of energy and macronutrient intake in the first 2 weeks of life with regional and total brain growth and white matter (WM) maturation, assessed by 3 serial MRI scans in preterm neonates; (2) to examine how critical illness modifies this association; and (3) to investigate the relationship with neurodevelopmental outcomes.
METHODS: Forty-nine preterm neonates (21 boys, median [interquartile range] gestational age: 27.6 [2.3] weeks) were scanned serially at the following median postmenstrual weeks: 29.4, …

Psychology Faculty Publications
Until recently, there were few rodent models available to study the interaction of post-traumatic stress disorder (PTSD) and drug taking. Like PTSD, single prolonged stress (SPS) produces hypothalamic-pituitary-adrenal (HPA) axis dysfunction and alters psychostimulant self-administration. Other stressors, such as isolation stress, also alter psychostimulant self-administration. However, it is currently unknown if isolation housing combined with SPS can alter the acquisition or maintenance of cocaine self-administration. The current study applied modified SPS (modSPS; two hours restraint immediately followed by cold swim stress) to rats raised in an isolation condition (Iso), enrichment condition (Enr), or standard condition (Std) to measure changes in …

Nmda Receptor Blockade Specifically Impedes The Acquisition Of Incentive Salience Attribution, Jonathan J. Chow, Joshua S. Beckmann
Psychology Faculty Publications
Glutamatergic signaling plays an important role in learning and memory. Using Pavlovian conditioned approach procedures, the mechanisms that drive stimulus-reward learning and memory have been investigated. However, there are instances where reward-predictive stimuli can function beyond being solely predictive and can be attributed with “motivational value” or incentive salience. Using a Pavlovian conditioned approach procedure consisting of two different but equally predictive stimuli (lever vs. tone) we investigated the role NMDA receptor function has in the attribution of incentive salience. The results revealed that the administration of MK-801, an NMDA receptor antagonist, during acquisition of Pavlovian conditioned approach promoted goal-tracking …

Research suggests that infants progress from discrimination to recognition of emotions in faces during the first half year of life. It is unknown whether the perception of emotions from bodies develops in a similar manner. In the current study, when presented with happy and angry body videos and voices, 5-month-olds looked longer at the matching video when they were presented upright but not when they were inverted. In contrast, 3.5-month-olds failed to match even with upright videos. Thus, 5-month-olds but not 3.5-month-olds exhibited evidence of recognition of emotions from bodies by demonstrating intermodal matching. In a subsequent experiment, younger infants …

This study addressed the development of attention to information that is socially relevant to adults by examining infants' (n = 64) scanning patterns of male and female bodies. Infants exhibited systematic attention to regions associated with sex-related scanning by adults, with 3.5-and 6.5-month-olds looking longer at the torso of females than males and longer at the legs of males than females. However, this pattern of looking was not found when infants were tested on headless bodies in Experiment 2, which suggests that infants' differential gaze pattern in Experiment 1 was not due to low-level stimulus features, such as clothing, and …

Very preterm human neonates are exposed to numerous invasive procedures as part of life-saving care. Evidence suggests that repetitive neonatal procedural pain precedes long-term alterations in brain development. However, to date the link between pain and brain development has limited temporal and anatomic specificity. We hypothesized that early exposure to painful stimuli during a period of rapid brain development, before pain modulatory systems reach maturity, will predict pronounced changes in thalamic development, and thereby cognitive and motor function. In a prospective cohort study, 155 very preterm neonates (82 males, 73 females) born 24-32 weeks' gestation underwent two MRIs at median …

Although the neural underpinnings of visually guided grasping and reaching have been well delineated within lateral and medial fronto-parietal networks (respectively), the contributions of subcomponents of visuomotor actions have not been explored in detail. Using careful subtraction logic, here we investigated which aspects of grasping, reaching, and pointing movements drive activation across key areas within visuomotor networks implicated in hand actions. For grasping tasks, we find activation differences based on the precision required (fine > coarse grip: anterior intraparietal sulcus, aIPS), the requirement to lift the object (grip + lift > grip: aIPS; dorsal premotor cortex, PMd; and supplementary motor area, SMA), …

Moral injury (MI) results from perpetration of or exposure to distressing events, known as morally injurious events (MIEs), that challenge moral beliefs and values. Due to the type of involvement in recent military conflicts, many veterans report MIEs that may cause dissonance and, in turn, MI. Although 2 existing measures assess MIEs, neither currently assesses the defining characteristics of MI (i.e., guilt, shame, difficulty forgiving self and others, and withdrawal). The present study reports the initial psychometric test of a modified version (Robbins, Kelley, Hamrick, Bravo, & White, 2017) of the Moral Injury Questionnaire—Military version (MIQ-M; Currier, Holland, Drescher, & …
