Creating A Balance In Sentencing Offenders: A Step Towards Restorative Justice, Lindsay Nichols Jan 2010

Creating A Balance In Sentencing Offenders: A Step Towards Restorative Justice, Lindsay Nichols

Master's Theses

Public sentencing preferences often determine the sentencing statutes created by legislators. Extracting public opinion is typically done through mass public opinion polls; however, research has found that these polls often produce misleading findings. In order to accurately dissect the various layers of laypersons' sentencing choices, a victim impact statement (VIS) and a statement of offender remorse were manipulated within a crime scenario depicting moderately severe crimes. A total of 215 participants were randomly assigned to one of the 16 conditions in this 2 (crime type: residential burglary or unarmed robbery) x 2 (VIS: absence or presence) x 2 (offender remorse …


Public Responsiveness To Victim's Recommendations In Their Sentencing Decisions: Role Of Victim's Race, Victim Impact Statement And Judge's Instructions, Mary Elizabeth Talbot Jan 2010

Public Responsiveness To Victim's Recommendations In Their Sentencing Decisions: Role Of Victim's Race, Victim Impact Statement And Judge's Instructions, Mary Elizabeth Talbot

Master's Theses

A total of 191 participants completed the 2 (Race of victim: African American, Caucasian) x 2 (Content of Victim Impact Statement (VIS): Sentence Recommendation Only, Both Sentence Recommendation and Harm Statement) x 2 (Jury Guidelines for VIS: No guidance, Explicit instructions to weigh the harm statement with other aggravating and mitigating factors) between subjects factorial design study. The study assessed the relationship between the victim's race (African-American or Caucasian), the content of victim impact statements, and the judge's guidelines/instructions for interpreting/using the Victim Impact Statement (VIS) in the sentencing phase of a defendant's trial for burglary and aggravated battery. The …


Investigation Of The Effects Of Team Coaching, Performance Feedback, And Collective Efficacy On Small Group Performance, Rachael Nichole Martinez Jan 2010

Investigation Of The Effects Of Team Coaching, Performance Feedback, And Collective Efficacy On Small Group Performance, Rachael Nichole Martinez

Master's Theses

Research has demonstrated that there are a variety of factors that influence group performance such as team coaching, feedback, and collective efficacy. A study was conducted to determine whether consultative team coaching improves performance and at what point--beginning or middle--it is most beneficial to the team. One hundred eleven dyads, comprised of 222 students, participated in this study. The dyads performed a task twice in which they were given team coaching before the first attempt, after the first attempt, or not at all. In addition, feedback was manipulated such that teams received positive or negative feedback after their first attempt …


Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones Dec 2009

Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones

Master's Theses

All mammalian females undergo behavioral and neurological changes during pregnancy and motherhood. Many of these changes lead to an enhanced ability to be an effective mother including: increased memory, foraging behaviors, and boldness. Here, we examined the differences in rehearsal strategies between mother and virgin rats. Stops made by rats when exploring their environment have been found to result in reverse replay activity in the hippocampus (Foster & Wilson, 2006). Reverse replay is sequential replay that occurs in the hippocampus immediately after a spatial experience; this replay/activation is in reversed order of the initial spatial episode (Foster & Wilson, 2006). …


Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas Aug 2009

Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas

Master's Theses

The female rat, among other species, undergoes a fundamental brain re-modeling as a consequence of experiencing the normal and natural events of pregnancy and offspring stimulation. Compelling data show that maternal experiences produce neurobiological modifications in the female leading to specific maternal behaviors, affective states, and the basic underlying female neurobiology necessary to raise viable offspring. This study aims to evaluate the number, quality and selective activation of neurons that develop during the maternal experience. The study showed a trend toward supporting the hypothesis that a “maternal-circuit” is formed through the proliferation of neurons during late-motherhood and lactation, and is …


Ethnic Identity And Sense Of School Belongingness: Behaviors And Beliefs Of Immigrant Hispanic Students And Parents, Francisco B. Ortiz Mar 2009

Ethnic Identity And Sense Of School Belongingness: Behaviors And Beliefs Of Immigrant Hispanic Students And Parents, Francisco B. Ortiz

Master's Theses

For many decades, the number of minority students, particularly Hispanics, dropping out from school has been noticeable to say the least (Rumberger, 1995). These students have in the past and continue in the present to struggle with the educational system, and it is certain, but not clear, that various factors contribute to Hispanics’ poor academic performance and not being able to graduate from High School (Rumbaut & Cornelius, 1995). Some of these factors are organized in three groups: School-Related; Parental-Related; and Student-Related. Thus, this study is an attempt to understand how immigrant students and parents are currently responding to the …


A Multi-Model Assessment Of Stereotype Content Of Three Latino Groups, Sandra Villalpando Jan 2009

A Multi-Model Assessment Of Stereotype Content Of Three Latino Groups, Sandra Villalpando

Master's Theses

The proposed research study deals with Latino groups' stereotypes, the content that makes up those stereotypes, and the effects the stereotypes have on Latinos' general well-being. This project investigates the origins of stereotype content using a general theory of stereotype content that is composed of two theories: social role theory (Eagly et al., 2000) and the stereotype content model (Fiske et al., 2003; Fiske et al., 1999). Short questionnaires on three different Latino groups in American society were completed by non-Latino respondents in the Chicago area, and an extended questionnaire on Latino groups was completed by Latino respondents in the …


Comparing Generation X To Generation Y On Work-Related Beliefs., Susana Fernandez Jan 2009

Comparing Generation X To Generation Y On Work-Related Beliefs., Susana Fernandez

Master's Theses

A new generation of employees with new expectations is entering the workplace. They are known by many names, but most will recognize them as the Millennials or Generation Y (Gen Y). With many Gen Y members already in the workforce, managers are likely to be required to deal with the generational differences that appear to exist among employees. Given that Gen Y members are likely to work closely with Gen X members, the present study explored possible differences between Gen X and Gen Y on their work-related beliefs.


Children's Use Of The Shape Bias In The Presence Of Different Instructions, Object Types, And Emotion Cues, Vanessa Raschke Jan 2009

Children's Use Of The Shape Bias In The Presence Of Different Instructions, Object Types, And Emotion Cues, Vanessa Raschke

Master's Theses

This study explored the prevalence of the shape bias in children when faced with multiple perceptual cues. Three-to six-year-olds were shown three-dimensional objects and two-dimensional representations of these objects, half of which had emotional faces depicted on them. Of interest was whether attention to emotion would alter children's bias towards the shape of the object and how dimensionality and instruction type would affect the children's choices. The older children were equally likely to use emotion matches as shape matches, but this was not the case for the younger children, who were almost exclusively focused on shape. The non-lexical instructions induced …


The Role Of Phonological Similarity In Constructing A Developing Lexicon, Lin Li Aug 2008

The Role Of Phonological Similarity In Constructing A Developing Lexicon, Lin Li

Master's Theses

The implicational hierarchy of phonological feature development has proposed that children acquire native phonemic inventory in a systematic way, from the least articulatory-effort-required phonemes to most demanding ones. On the phonemic inventory level, the hierarchy suggests that perceptual features bearing by oral stops /p/, /b/, /t/, /d/, /k/, /g/ would appear ahead of perceptual features bearing by fricatives, affricatives and liquids ... while nasals stops ... would emerge in the middle. With the help of age-of-acquisition index and a phonemic change schema, the distributions of 489 phonological neighbors have been examined against the data from MacArthur Communicative Development Inventory to …


Attentive Mothers Versus Minimally Invested/Neglectful Mothers : The Development Of New Neurons In The Hippocampus Specifically Activated By Foster Pup Exposure, Danielle Christina Worthington Stoneman Aug 2008

Attentive Mothers Versus Minimally Invested/Neglectful Mothers : The Development Of New Neurons In The Hippocampus Specifically Activated By Foster Pup Exposure, Danielle Christina Worthington Stoneman

Master's Theses

As pregnancy progresses, the female is transformed from an animal that actively avoids pup-related cues (Kinsley, 1994) to one highly motivated to build nests, and retrieve, group, groom, and crouch over a set of pups. In the vast majority of events, motherhood progresses normally; in a striking subset, however, it does not. This study seeks to evaluate neurological differences in the dentate gyrus between primiparous females that respond maternally and those that do not when exposed to foster pups. It was hypothesized that the attentive mothers which perform the expected maternal behaviors have a different number of triple labeled BrdU(measuring …


The Effects Of Target Age And Perceived Death Responsibility On Posthumous Impression Formations, Jenny Rebekah Heilborn Jan 2008

The Effects Of Target Age And Perceived Death Responsibility On Posthumous Impression Formations, Jenny Rebekah Heilborn

Master's Theses

Death positivity biases and posthumous evaluations are considered a universal normative social phenomenon which influences social judgments of the dead; we postulate that these individual biases are mediated by both sympathy and fear of mortality, or the belief in a just world. Study 1 postulated that sympathy mediates such positivity biases when target responsibility for cause of death is manipulated. We hypothesized the mediation of the just world violation on posthumous evaluatory measures when age at the time of death was manipulated in Study 2. Although results were inconclusive for both studies, alternate hypotheses and boundary conditions of death positivity …


Automatic Spatial Processing Of Threatening And Positive Information In Participants With High And Low Levels Of Trait Anxiety, Ryan W. Hansen Aug 2007

Automatic Spatial Processing Of Threatening And Positive Information In Participants With High And Low Levels Of Trait Anxiety, Ryan W. Hansen

Master's Theses

The study sought to investigate potential differences in automatic spatial processing of threatening and positive information in anxious and non-anxious individuals. Participants evaluated threatening and positive words and pictures in a memory task in which the stimuli's varying spatial position was incidental to the task. Participants demonstrated increased accuracy with threatening stimuli, and a decreased accuracy when the word location varied between initial presentation and test. The results did not provide evidence that threatening stimuli were associated with an increased degree of spatial processing, or that this relationship would be influenced by trait anxiety.


Motherhood, Memory And Aging : Object Recognition Performance, Julia Margaret Friedenberg Aug 2007

Motherhood, Memory And Aging : Object Recognition Performance, Julia Margaret Friedenberg

Master's Theses

Reproductively experienced female rats have been shown to have attenuated stress responses, improved visual systems, and better memory and learning. This study sought to extend those findings by comparing aged reproductively experienced and aged virgin female rats on an object recognition task, as well as comparing levels of corticosterone and 17p-estradiol and neural activation. Multiparous (MP, 2 reproductive experiences) females performed better on the task and demonstrated quicker habituation to the task than nulliparous (NP, no reproductive experiences) females. No hormonal or neural activation differences were found. The present study contributes to the growing research areas of reproductive experience and …


Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon Aug 2007

Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon

Master's Theses

Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test. Social behavior and neural oxytocin and vasopressin were assessed post-testing, while corticosterone levels were measured across the four weeks. Weaning was extremely stressful for all offspring. PP- and MP-raised pups exhibited differences in social behavior, …


Early Vocabulary Development In English, Mandarin, And Cantonese : A Cross-Linguistic Study Based On Childes, Shuxia Liu Aug 2007

Early Vocabulary Development In English, Mandarin, And Cantonese : A Cross-Linguistic Study Based On Childes, Shuxia Liu

Master's Theses

Early language development is an exciting topic in the field of child language acquisition. Only a limited amount of cross-linguistic studies has attempted to investigate the similarities and differences in child language development across different languages. In this thesis, I present a study based on English, Mandarin and Cantonese corpora extracted from the Child Language Data Exchange System (CHILDES, MacWhinney, 2000). I investigated the lexical compositions of certain lexical categories (nouns, verbs, and adjectives) in children and their caregivers’ vocabularies across eight different children age groups ranging from 13 to 60 months. ANOVA, frequency analysis, and cluster analysis were used …


A Role For Vasopressin And Oxytocin In Parental Behavior Of The Male Sprague-Dawley Rat, Ekaterina V. Karelina Aug 2006

A Role For Vasopressin And Oxytocin In Parental Behavior Of The Male Sprague-Dawley Rat, Ekaterina V. Karelina

Master's Theses

Paternal behavior, though infrequent in many mammalian species, can be induced under laboratory conditions through manipulation of either hormonal or environmental states. Rodent studies of parental behavior have implicated similarities for males and females in not only the actual behavioral repertoire, but also the brain mechanisms governing the set of behaviors in both sexes. The current project investigated changes in oxytocin and vasopressin in the hypothalamus of paternal male rats. We found that paternal behavior, which was readily induced through sensitization (chronic pup exposure), was significantly correlated with increasing oxytocin and vasopressin immunoreactivity within the paraventricular nucleus. Further, corticosterone levels …


Learned Fear And Reaction To Novel Stimuli: Behavioral And Hormonal Stress Responses In The Maternal Rat, Brandi Nicole Rima Aug 2006

Learned Fear And Reaction To Novel Stimuli: Behavioral And Hormonal Stress Responses In The Maternal Rat, Brandi Nicole Rima

Master's Theses

The present thesis examines the relationship between reproductive experience and the behavioral, neural, and hormonal processes of learned fear in the female rat. Multiple research models indicate that reproductive experience functions to decrease the female's stress response in potentially harmful environments, thus providing her with numerous survival benefits, including decreased fearfulness, increased aggression, and refined hunting skills. Based on existing understandings of maternal experience and unconditioned fear, this study was designed to determine how nulliparous (no reproductive experience, NP), primiparous (one reproductive experience, PP) and multiparous (more than one reproductive experience, MP) rats comparatively respond to a Pavlovian paradigm of …


Conditional Love : A Study Of Situational Differences In Rooting For An Underdog, Sheila Margaret Hindle May 2006

Conditional Love : A Study Of Situational Differences In Rooting For An Underdog, Sheila Margaret Hindle

Master's Theses

While people tend to root unabashedly for underdogs in the domain of athletics, underdogs do not generally receive the same tremendous support in matters of business. This may occur for a variety of reasons, but of particular interest is the fact that an individual's perception of a situation as both self-relevant and of high consequences may prove detrimental to his or her willingness to support an underdog. Two studies were conducted to explore these hypotheses. Study 1 (N=48) required participants to read a brief scenario depicting a situation of varied self-relevance and consequences, and then select a company to complete …


Predictors Of Breast And Cervical Cancer Screening Among Vietnamese Immigrant Women, Anh B. Nguyen May 2006

Predictors Of Breast And Cervical Cancer Screening Among Vietnamese Immigrant Women, Anh B. Nguyen

Master's Theses

Predictors of breast and cervical cancer screening among Vietnamese immigrant women. Anh B. Nguyen, Master of Arts in Psychology, University of Richmond, 2006. Thesis director: Barbara K. Sholley, Ph.D Although practicing preventative healthcare is an important part of a healthy lifestyle, some high-risk populations do not engage in preventative screenings for cancer. Vietnamese American women constitute a high-risk group in gynecological cancers, and it was hypothesized that tenure, acculturation, health insurance, a regular source of care, education, employment status, and marital status would affect rates of cancer screening. It was also hypothesized that the Vietnamese population would have different trends …


Self-Esteem And The Underdog : Why Stability Of Self-Esteem Matters In Social Situations, Kelly Dyjak Aug 2005

Self-Esteem And The Underdog : Why Stability Of Self-Esteem Matters In Social Situations, Kelly Dyjak

Master's Theses

Differences related to self-esteem and their possible influences on perceptions of underdogs were investigated. Global self-esteem and stability of self-esteem were evaluated using The Rosenberg Self-Esteem Scale. Participants' self-esteem was threatened by using the false feedback technique. Finally, perceptions of a competition between an underdog and a top dog were evaluated. The results demonstrated that although participants with stable and unstable self-esteem favor the underdog, participants with unstable self-esteem favor the underdog even more than the participants with stable self-esteem. The findings reinforce the robustness of the underdog effect and highlight a consequence of having unstable self-esteem.


A Cognitive Intervention To Increase The Salience Of Intrinsic Thoughts Associated With Exercise, Katie S. Moran Aug 2005

A Cognitive Intervention To Increase The Salience Of Intrinsic Thoughts Associated With Exercise, Katie S. Moran

Master's Theses

A four-week cognitive intervention was created to increase the salience of intrinsic thoughts associated with exercise in moderately extrinsic exercisers. Participants were assigned to either an intervention or control condition. Those in the intervention condition were asked to respond to questions concerning the pleasure, enjoyment and/or satisfaction experienced during or after their exercise regimen each week. Results showed a marginally significant two-way interaction (p = .059) between the control and intervention condition over time. Those in the intervention condition showed a greater increase in intrinsic motivation than those in the control condition. These results. while only marginally significant, were in …


Sentence Recognition In Native And Foreign Languages : Comprehension Of Form And Meaning, Sara Elizabeth Sepanski Jul 2005

Sentence Recognition In Native And Foreign Languages : Comprehension Of Form And Meaning, Sara Elizabeth Sepanski

Master's Theses

The goal of language comprehension is to retrieve and retain the meaning of speech or text. Research with monolinguals has shown that participants' ability to detect structural changes in sentences decreases with time, while their ability to detect meaning changes remains accurate (Sachs, I967). In this study I examined whether this monolingual pattern holds for bilingual speakers in a second language. English-Spanish bilinguals at three different proficiency levels participated in a reading task in which native (LI) and non-native (L2) language sentences were presented. Participants read both LI and L2 sentences and were then tested for their recognition of the …


Affective Benefits Of Capitalizing On Personal Positive Events, Daniel B. Goldman Jun 2005

Affective Benefits Of Capitalizing On Personal Positive Events, Daniel B. Goldman

Master's Theses

The present study examined how disclosing personal positive events influenced ensuing positive affect (PA). Forty undergraduate students reported personal positive events either privately or to a friend. All participants made written and vocal disclosures, counterbalanced to control for order effects. We hypothesized that participants who vocally reported positive experiences to a friend would have the highest PA scores subsequent to disclosure. Results from a two-way mixed ANOV A failed to support the hypothesis. Trait optimism was significantly related to positive affect, but its inclusion as a covariate in the ANOV A did not influence the pattern of results. These results …


The Life-Long Diminution Of Anxiety Response As A Consequence Of Reproductive Experience, Ilan M. Mcnamara Aug 2004

The Life-Long Diminution Of Anxiety Response As A Consequence Of Reproductive Experience, Ilan M. Mcnamara

Master's Theses

Reproductive experience (RE), associated with hormonal fluctuations and enriching environmental stimuli, enhances spatial memory and blunts responses to stress/anxiety. Whereas stress reductions occur during lactation, the persistence of the RE-anxiolytic effects is unclear; and little research has focused on the HP A axis, amygdala, and other anxietyrelated areas. Using an elevated plus maze (EPM), we examined anxiety in nulliparous (NP), primiparous (PP), and multiparous (MP) females (zero, one, or two litters, respectively) at 6, 10, 14, 18, and 22 months of age. Brains were subsequently analyzed for neurodegeneration in dorsal raphe nucleus (DRN). RE significantly dampened anxiety (defined by time …


The Relationship Between Age And Depression : A Self-Efficacy Model, Brandyn M. Street Jun 2004

The Relationship Between Age And Depression : A Self-Efficacy Model, Brandyn M. Street

Master's Theses

From an applied perspective, it is useful for clinicians and researchers to know what variables are more likely to be related to depressive symptoms for some groups than for others. From the social-cognitive perspective, symptoms of depression are linked to people's beliefs that they are unable to regulate or control their own functioning. The purpose of the present study was to test social cognitive theory and its claims about self efficacy by examining whether age and sex differences in depression are a function of emotion regulation, emotional self-efficacy and response styles to depression. The results indicated that females had a …


"Paper Sack Brown" : Effects Of Age, Skin Tone, And Stereotype Threat On Cognitive Performance And Self-Efficacy Among African Americans, Breonte Stephan Guy Aug 2003

"Paper Sack Brown" : Effects Of Age, Skin Tone, And Stereotype Threat On Cognitive Performance And Self-Efficacy Among African Americans, Breonte Stephan Guy

Master's Theses

Divergent African American skin tones have led to negative stereotypes and outcomes regarding darker-skinned African Americans in many domains, including educational and occupational (Hill, 2002). This study assessed the effects of skin tone and stereotype threat (Steele and Aronson, 1995; Steele, 1997) on cognition in younger and older African Americans. A 2(Skin Tone: light, dark) X 2(Age: young, old) X 2(Stereotype Threat: Threat, Non-Threat) between subjects design was used. Seventy-four African American adults ranging in age from 18 to 86 years completed a battery of cognitive measures. Darker-skinned adults performed more poorly on three tests of intelligence, a paired-associates memory …


The Presence Of Pups After Birth : Effects On Spatial Memory And The Pre-Synaptic Protein Synaptophysin, Abbe Hoffman Macbeth Aug 2003

The Presence Of Pups After Birth : Effects On Spatial Memory And The Pre-Synaptic Protein Synaptophysin, Abbe Hoffman Macbeth

Master's Theses

A newly maternal rat goes through many changes when she gives birth, mostly due to prolonged elevation of hormones, particularly estrogen. Estrogen has been shown to increase memory capabilities by increasing synaptic activity in the CA1 hippocampus, but exactly how is still unknown. The current project uses reproductive experience to determine whether high hormone levels experienced during pregnancy and lactation affect spatial memory and synaptophysin, a pre-synaptic protein that controls vesicle exocytosis and thus may be responsible for enhanced synaptic connectivity. We found that reproduction itself does not affect memory of a spatial task, but the presence of pups has …


Brain-Derived Neurotrophic Factor And Maternal Behavior : Neuronal Alterations In The Medial Preoptic Area And Suppression Of Pup Attacks, Lillian Flores Stevens Aug 2003

Brain-Derived Neurotrophic Factor And Maternal Behavior : Neuronal Alterations In The Medial Preoptic Area And Suppression Of Pup Attacks, Lillian Flores Stevens

Master's Theses

Brain-derived neurotrophic factor (BDNF), by virtue of its relationship to various neurotransmitter systems, hormones, and to estrogen in particular, may play a role in maternal behavior. To explore this possible role, female virgin Sprague Dawley rats received continuous intracerebroventricular infusions ofBDNF sense oligonucleotide and were exposed to pups for maternal behavior testing. Behaviorally, BDNF sense had no effect on maternal behavior but did significantly suppress pup attacks during the first 24 hours of exposure. BDNF had a significant effect on neuronal morphology in the medial preoptic area (mPOA) as well, such that neurons in this region exposed to BDNF had …


The Effects Of Childhood Social Competence On Young Adults Interpersonal Competence In Dyadic And Family Relations: An Exploratory Analysis, Gwen Renae Pursell Aug 2002

The Effects Of Childhood Social Competence On Young Adults Interpersonal Competence In Dyadic And Family Relations: An Exploratory Analysis, Gwen Renae Pursell

Master's Theses

The majority of peer relations research focuses on the short and long term effects of childhood peer rejection and aggression for development. The importance of social competence and more specifically, its long term effects on development have not been as thoroughly examined within the peer research. In this 20 year follow-up investigation, preadolescent social competence, peer rejection, and aggression scores were used to predict adult measures of dyadic adjustment, family environment, and family expressiveness. In addition, both preadolescent peer relation scores and concurrent adult dyadic and family scores were used to predict offspring emotion regulation abilities, internalizing and externalizing symptomatology, …
