The Relationship Between The Perception Of Axes Of Symmetry And Spatial Memory During Early Childhood, Margaret R. Ortmann, Anne R. Schutte 2010 University of Nebraska-Lincoln

The Relationship Between The Perception Of Axes Of Symmetry And Spatial Memory During Early Childhood, Margaret R. Ortmann, Anne R. Schutte

Faculty Publications, Department of Psychology

Early in development, there is a transition in spatial working memory (SWM). When remembering a location in a homogeneous space (e.g., in a sandbox), young children are biased toward the midline symmetry axis of the space. Over development, a transition occurs that leads to older children being biased away from midline. The dynamic field theory (DFT) explains this transition in biases as being caused by a change in the precision of neural interaction in SWM and improvements in the perception of midline. According to the DFT, young children perceive midline, but there is a quantitative improvement in the perception ...


Stereotype Boost And Stereotype Threat Effects: The Moderating Role Of Ethnic Identification, Brian E. Armenta 2010 University of Nebraska–Lincoln

Stereotype Boost And Stereotype Threat Effects: The Moderating Role Of Ethnic Identification, Brian E. Armenta

Faculty Publications, Department of Psychology

Belonging to a stereotyped social group can affect performance in stereotype-relevant situations, often shifting performance in the direction of the stereotype. This effect occurs similarly for members of positively and negatively stereotyped groups (i.e., stereotype boost and stereotype threat, respectively). This study examined ethnic group identification as a moderator of these effects in the math performance of Asian Americans and Latinos, who are positively and negatively stereotyped in this domain, respectively. Results showed that high ethnically identified Asian Americans performed better and high ethnically identified Latinos performed worse when an ethnicity– ethnic stereotype cue was present. The performance of ...


The Whitings’ Concepts Of Culture And How They Have Fared In Contemporary Psychology And Anthropology, Carolyn P. Edwards, Marianne Bloch 2010 University of Nebraska-Lincoln

The Whitings’ Concepts Of Culture And How They Have Fared In Contemporary Psychology And Anthropology, Carolyn P. Edwards, Marianne Bloch

Faculty Publications, Department of Psychology

This article presents a brief intellectual biography of John and Beatrice Whiting, followed by an examination of five key ideas that they put forward to the fields of psychology and anthropology through their theoretical and empirical writings. These key ideas are (a) the assumption of the psychic unity of humankind, (b) the cultural learning environment, (c) the psychocultural model, (d) the synergistic relationship of the disciplines of psychology and anthropology, and (e) the role of mothers as agents of social change through child-rearing roles as well as through various other ways they guide change in the communities and learning environments ...


Punished, Dead Or Alive: Empirical Perspectives On Awarding Punitive Damages Against Deceased Defendants, Timothy R. Robicheaux, Brian H. Bornstein 2010 University of Nebraska-Lincoln

Punished, Dead Or Alive: Empirical Perspectives On Awarding Punitive Damages Against Deceased Defendants, Timothy R. Robicheaux, Brian H. Bornstein

Faculty Publications, Department of Psychology

Punitive damages are a tool for punishing defendants who engage in reckless and wanton behaviors that cause injury to others. As with criminal punishment, goals of punitive damages include retribution, specific deterrence, and general deterrence. Unlike criminal punishment, however, some courts allow punitive damages to follow the death of defendants. To explore this issue, we first conducted a legal analysis of appellate court decisions concerning punitive damages against deceased defendants. While the majority of courts suggest that punitive damages against deceased individuals are not appropriate, some argue that favorable policy implications of allowing punitive damages to follow the defendant’s ...


Aging And The Vulnerability Of Speech To Dual Task Demands, Susan Kemper, RaLynn Schmalzried, Lesa Hoffman, Ruth Herman 2010 University of Kansas

Aging And The Vulnerability Of Speech To Dual Task Demands, Susan Kemper, Ralynn Schmalzried, Lesa Hoffman, Ruth Herman

Faculty Publications, Department of Psychology

Tracking a digital pursuit rotor task was used to measure dual task costs of language production by young and older adults. Tracking performance by both groups was affected by dual task demands: time on target declined and tracking error increased as dual task demands increased from the baseline condition to a moderately demanding dual task condition to a more demanding dual task condition. When dual task demands were moderate, older adults’ speech rate declined but their fluency, grammatical complexity, and content were unaffected. When the dual task was more demanding, older adults’ speech, like young adults’ speech, became highly fragmented ...


Intertemporal Choice, Jeffrey R. Stevens 2010 University of Nebraska-Lincoln

Intertemporal Choice, Jeffrey R. Stevens

Faculty Publications, Department of Psychology

A Clark’s nutcracker (Nucifraga columbiana) flies to the top of a pine tree and selects one of the many cones. She twists and pecks at the stem until the cone breaks free from the branch and, with one foot, holds the cone in the crotch of a branch. She then repeatedly hammers her long bill in between the scales of the cone. After forcing out one of the seeds, she tips her head back a bit, clicks the seed in her bill a few times, and closes her bill. A few minutes later, the shredded cone drops to the ...


Rational Decision Making In Primates: The Bounded And The Ecological, Jeffrey R. Stevens 2010 University of Nebraska-Lincoln

Rational Decision Making In Primates: The Bounded And The Ecological, Jeffrey R. Stevens

Faculty Publications, Department of Psychology

Primates constantly face decisions that influence their survival and reproduction. Continue foraging in this tree or move on to another? Expose oneself to a hidden predator by straying from the group or enjoy the safety of having other potential victims nearby? Defend one’s territory from invaders or abandon it and seek a new home? In all of these cases, primates must trade off the costs and benefits associated with uncertain and delayed decision outcomes. The outcomes of these choices influence survival and reproduction, and natural selection should favor those individuals whose choices lead to the propagation of their genes ...


Physical, Psychological, And Sexual Intimate Partner Aggression Among Newlywed Couples: Longitudinal Prediction Of Marital Satisfaction, Jillian Panuzio, David K. DiLillo 2010 University of Nebraska-Lincoln

Physical, Psychological, And Sexual Intimate Partner Aggression Among Newlywed Couples: Longitudinal Prediction Of Marital Satisfaction, Jillian Panuzio, David K. Dilillo

Faculty Publications, Department of Psychology

This study examined associations between physical, psychological, and sexual intimate partner aggression (IPA) perpetration during the first year of marriage (T1) and victim marital satisfaction one (T2) and two (T3) years later among a sample of 202 newlywed couples. Prevalence rates of all forms of IPA were consistent with those documented in prior research. Higher levels of all types of IPA generally were associated with lower victim marital satisfaction at all time points, when controlling for initial levels of satisfaction. Couples who reported severe bidirectional psychological IPA demonstrated lower husband and wife marital satisfaction at T2 and lower husband satisfaction ...


Emotion Dysregulation And Risky Sexual Behavior In Revictimization, Terri L. Messman-Moore, Kate L. Walsh, David K. DiLillo 2010 Miami University - Oxford

Emotion Dysregulation And Risky Sexual Behavior In Revictimization, Terri L. Messman-Moore, Kate L. Walsh, David K. Dilillo

Faculty Publications, Department of Psychology

Objective: The current study examined emotion dysregulation as a mechanism underlying risky sexual behavior and sexual revictimization among adult victims of child sexual abuse (CSA) and child physical abuse (CPA).

Methods: Participants were 752 college women. Victimization history, emotion dysregulation, and risky sexual behavior were assessed with anonymous, self-report surveys utilizing a cross-sectional design.

Results: Approximately 6.3% of participants reported CSA, 25.5% reported CPA, and 17.8% reported rape during adolescence or adulthood. CSA and CPA were associated with increased risk for adolescent/adult rape; 29.8% of CSA victims and 24.3% of CPA victims were revictimized ...


Distinct Neural Mechanisms Underlying Acute And Repeated Administration Of Antipsychotic Drugs In Rat Avoidance Conditioning, Ming Li, Tao Sun, Chen Zhang, Gang Hu 2010 University of Nebraska-Lincoln

Distinct Neural Mechanisms Underlying Acute And Repeated Administration Of Antipsychotic Drugs In Rat Avoidance Conditioning, Ming Li, Tao Sun, Chen Zhang, Gang Hu

Faculty Publications, Department of Psychology

Rationale — Acute antipsychotic treatment disrupts conditioned avoidance responding, and repeated treatment induces a sensitization- or tolerance-like effect. However, the neurochemical mechanisms underlying both acute and repeated antipsychotic effects remain to be determined.

Objective — The present study examined the neuroreceptor mechanisms of haloperidol, clozapine, and olanzapine effect in a rat two-way conditioned avoidance model.

Methods — Well-trained Sprague–Dawley rats were administered with haloperidol (0.05 mg/kg, sc), clozapine (10.0 mg/ kg, sc), or olanzapine (1.0 mg/kg, sc) together with either saline, quinpirole (a selective dopamine D2/3 agonist, 1.0 mg/ kg, sc), or 2,5-dimethoxy-4-iodo-amphetamine (DOI ...


Psychometric Properties Of The Pyramids And Palm Trees Test, Gerasimos Fergadiotis, Heather Wright, Gilson Capilouto 2010 Portland State University

Psychometric Properties Of The Pyramids And Palm Trees Test, Gerasimos Fergadiotis, Heather Wright, Gilson Capilouto

Speech and Hearing Sciences Faculty Publications and Presentations

The Pyramids and Palm Trees Test (PPT) is a nonverbal measure of semantic memory that has been frequently used in previous aphasia, agnosia, and dementia research. Very little psychometric information regarding the PPT is available. The purpose of this study was to investigate the psychometric properties of the PPT in a population of healthy college students. Results indicated that the PPT achieved poor test–retest reliability, failed to obtain adequate internal consistency, and demonstrated poor convergent validity, but showed acceptable discriminant validity. The results of this study suggest that the PPT lacks acceptable reliability and validity for use with a ...


The Isolation Of Viruses Infecting Archaea, Kenneth M. Stedman, Kate Porter, Mike L. Dyall-Smith 2010 Portland State University

The Isolation Of Viruses Infecting Archaea, Kenneth M. Stedman, Kate Porter, Mike L. Dyall-Smith

Biology Faculty Publications and Presentations

A mere 50 viruses of Archaea have been reported to date; these have been investigated mostly by adapting methods used to isolate bacteriophages to the unique growth conditions of their archaeal hosts. The most numerous are viruses of thermophilic Archaea. These viruses have been discovered by screening enrichment cultures and novel isolates from environmental samples for their ability to form halos of growth inhibition, or by using electron microscopy to screen enrichment cultures for virus-like particles. Direct isolation without enrichment has not yet been successful for viruses of extreme thermophiles. On the other hand, most viruses of extreme halophiles, the ...


Communalism Predicts Prenatal Affect, Stress, And Physiology Better Than Ethnicity And Socioeconomic Status, Cleopatra M. Abdou, Christine Dunkel Schetter, Belinda Campos, Clayton J. Hilmert, Tyan Parker Dominguez, Calvin J. Hobel, Laura M. Glynn, Curt A. Sandman 2010 University of Michigan

Communalism Predicts Prenatal Affect, Stress, And Physiology Better Than Ethnicity And Socioeconomic Status, Cleopatra M. Abdou, Christine Dunkel Schetter, Belinda Campos, Clayton J. Hilmert, Tyan Parker Dominguez, Calvin J. Hobel, Laura M. Glynn, Curt A. Sandman

Psychology Faculty Articles and Research

The authors examined the relevance of communalism, operationalized as a cultural orientation emphasizing interdependence, to maternal prenatal emotional health and physiology and distinguished its effects from those of ethnicity and childhood and adult socioeconomic status (SES). African American and European American women (N = 297) were recruited early in pregnancy and followed through 32 weeks gestation using interviews and medical chart review. Overall, African American women and women of lower socioeconomic backgrounds had higher levels of negative affect, stress, and blood pressure, but these ethnic and socioeconomic disparities were not observed among women higher in communalism. Hierarchical multivariate regression analyses showed ...


Chemosensitization Of Cancer Cells By Sirna Using Targeted Nanogel Delivery, Erin B. Dickerson, William H. Blackburn, Michael H. Smith, Laura B. Kapa, L. Andrew Lyon, John F. McDonald 2010 Georgia Institute of Technology

Chemosensitization Of Cancer Cells By Sirna Using Targeted Nanogel Delivery, Erin B. Dickerson, William H. Blackburn, Michael H. Smith, Laura B. Kapa, L. Andrew Lyon, John F. Mcdonald

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Background: Chemoresistance is a major obstacle in cancer treatment. Targeted therapies that enhance cancer cell sensitivity to chemotherapeutic agents have the potential to increase drug efficacy while reducing toxic effects on untargeted cells. Targeted cancer therapy by RNA interference (RNAi) is a relatively new approach that can be used to reversibly silence genes in vivo by selectively targeting genes such as the epidermal growth factor receptor (EGFR), which has been shown to increase the sensitivity of cancer cells to taxane chemotherapy. However, delivery represents the main hurdle for the broad development of RNAi therapeutics.

Methods: We report here the use ...

Pharmacy Faculty Articles and Research

Background: Human Cytomegalovirus (HCMV) has been implicated in the acceleration of vascular disease and chronic allograft rejection. Recently, the virus has been associated with glioblastoma and other tumors. We have previously shown that the HCMV-encoded chemokine receptor pUS28 mediates smooth muscle cell (SMC) and macrophage motility and this activity has been implicated in the acceleration of vascular disease. pUS28 induced SMC migration involves the activation of the protein tyrosine kinases (PTKs) Src and Focal adhesion kinase as well as the small GTPase RhoA. The PTK Pyk2 has been shown to play a role in cellular migration and formation of cancer ...


Australian Mental Health Consumers' Contributions To The Evaluation And Improvement Of Recovery-Oriented Service Provision, Sarah L. Marshall, Lindsay G. Oades, Trevor P. Crowe 2010 Australian Catholic University

Australian Mental Health Consumers' Contributions To The Evaluation And Improvement Of Recovery-Oriented Service Provision, Sarah L. Marshall, Lindsay G. Oades, Trevor P. Crowe

Faculty of Health Sciences Publications

Background: one key component of recovery-oriented mental health services, typically overlooked, involves genuine collaboration between researchers and consumers to evaluate and improve services delivered within a recovery framework. Method: Eighteen mental health consumers working with staff who had received training in the Collaborative recovery Model (CrM) took part in in-depth focus group meetings, of approximately 2.5 hours each, to generate feedback to guide improvement of the CrM and its use in mental health services. Results: Consumers identified clear avenues for improvement for the CrM both specific to the model and broadly applicable to recovery-oriented service provision. Findings suggest consumers ...


Blood/Lust: Freud And The Trauma Of Killing In War, Nolen Gertz 2010 CUNY New York City College of Technology

Blood/Lust: Freud And The Trauma Of Killing In War, Nolen Gertz

Publications and Research

During World War I, Sigmund Freud and his followers held a special symposium in Budapest entitled "Psycho-Analysis and the War Neuroses." Their contributions centered on the importance of trying to understand what can cause a soldier to become traumatized in war by investigating the individual factors of each case as opposed to merely the situational factors. Thus by redefining such ambiguous illnesses as shell shock and war strain into the Freudian framework of the traumatic neuroses, they were able to do what the neurologists could not — explain the meaning behind the soldiers' symptoms and treat them with successful results. However ...


Socio-Cultural Factors Influencing Male Involvement In Reproductive Health During Pregnancy, Childbirth And The Postnatal Period In Rural Districts Of Malawi, Jane Dzumbila-Namasasu 2010 Edith Cowan University

Socio-Cultural Factors Influencing Male Involvement In Reproductive Health During Pregnancy, Childbirth And The Postnatal Period In Rural Districts Of Malawi, Jane Dzumbila-Namasasu

Theses: Doctorates and Masters

This thesis focuses on socio cultural factors influencing male involvement in reproductive health during pregnancy, childbirth and the postnatal period in rural districts of Malawi. This research stems from my fourteen years of experience in designing and overseeing the implementation of reproductive health services in Malawi, which led me to question why men as partners/husbands are not considered in the design and implementation of such services. Men as partners/husbands bear witness to most of the reproductive health problems that women go through and they are in a position of power, making decisions for their families‟ welfare. In addition ...


Conceptualising Bullying In An Aboriginal Context As Reported By The Yamaji Community, To Inform The Development Of A Bullying Prevention Program That Is Culturally Sensitive To The Needs Of Aboriginal Students, Juli Coffin 2010 Edith Cowan University

Conceptualising Bullying In An Aboriginal Context As Reported By The Yamaji Community, To Inform The Development Of A Bullying Prevention Program That Is Culturally Sensitive To The Needs Of Aboriginal Students, Juli Coffin

Theses: Doctorates and Masters

The Solid Kids Solid Schools project aimed to capture the unheard voices of Aboriginal children and community members on the issues surrounding ‘bullying’. In an Aboriginal context bullying is different and the outcomes are different, yet mainstream programs are utilized to combat the issue. We need to know how bullying is different for Aboriginal children and young people, why it is different and what does this difference mean in terms of addressing this issue in a school and community setting? A community based steering group guided the direction of this study and the larger Solid Kids Solid Schools project. Snowball ...


Low Back Pain In Schoolgirl Rowers: Prevalence, Bio-Psycho-Social Factors And Prevention, Debra Perich 2010 Edith Cowan University

Low Back Pain In Schoolgirl Rowers: Prevalence, Bio-Psycho-Social Factors And Prevention, Debra Perich

Theses: Doctorates and Masters

Rowing is one of the largest participant sports on the Independent Girls‟ Schools Sporting Association (IGSSA) in Western Australia with approximately 400 participants competing every year. Rowing is an extra-curricular sport offered to girls 14 years of age and above, with these girls competing and training in both sweep and scull boats. Whilst the benefits of regular physical activity and exercise are well known, musculoskeletal problems have been documented in rowing. In particular, clinical evidence and previous research suggests that low back pain (LBP) is common in rowers. Adolescents who suffer from LBP are at an increased risk of recurrent ...
