Predicting The Readability Of Transparent Text, Lauren F. V. Scharff, Albert J. Ahumada Jr.

Faculty Publications

Will a simple global masking model based on image detection be successful at predicting the readability of transparent text? Text readability was measured for two types of transparent text: additive (as occurs in head-up displays) and multiplicative (which occurs in see-through liquid crystal display virtual reality displays). Text contrast and background texture were manipulated. Data from two previous experiments were also included (one using very low contrasts on plain backgrounds, and the other using higher-contrast opaque text on both plain and textured backgrounds). All variables influenced readability in at least an interactive manner. When there were background textures, the global …

The latter focused exclusively on conflict experiences. Females reported stronger …

Recruitment Of Engaged Couples For Premarital Counseling: An Empirical Examination Of The Importance Of Program Characteristics And Topics To Potential Participants, Kieran T. Sullivan, Carmen Anderson

Psychology

The recent emphasis on prevention in helping couples to avoid marital distress may be limited by lack of participation in prevention programs by engaged couples. The purpose of this study is to understand what potential participants perceive are attractive characteristics in premarital prevention approaches. Eighty-six engaged couples completed questionnaires assessing demographics, personality and the relative importance of premarital program characteristics. The results indicate that leader characteristics, content, and topics such as communication, finances, and problem-solving are the most important elements of premarital counseling to couples. Differences based on gender and risk level are reported. Suggestions are made for more effective …

Revisiting The Picture-Superiority Effect In Symbolic Comparisons: Do Pictures Provide Privileged Access?, Paul Amrhein, Mark Mcdaniel, Paula Waddill

Department of Psychology Faculty Scholarship and Creative Works

In 4 experiments, symbolic comparisons were investigated to test semantic-memory retrieval accounts espousing processing advantages for the picture over word stimuli. In Experiment 1, participants judged pairs of animal names or pictures by responding to questions probing concrete or abstract attributes (texture or size, ferocity or intelligence). Per pair, attributes were salient or nonsalient concerning their prerated relevance to animals being compared. Distance (near or far) between attribute magnitudes was also varied. Pictures did not significantly speed responding relative to words across all other variables. Advantages were found for far attribute magnitudes (i.e., the distance effect) and salient attributes. The …

Distributive Justice And Punishment In Team Sports, David Bucur

Masters Theses & Specialist Projects

Distributive justice outcomes of punishment in an intercollegiate team sport setting were investigated. Male intercollegiate athletes (#=148) participating in the NAIA National Soccer Championship Tournament responded to one of eight scenarios and reported perceived fairness to player, fairness to teammates, deterrence to future player misconduct, and deterrence to future teammate misconduct. The results indicated that athletes perceive consistent distribution of punishment as more fair than conditional distribution of punishment; consistently distributed punishment is perceived to be more likely to deter future misconduct than conditional punishment; punishment, in general, is perceived as more fair when the violation committed is severe as …

A Study Of The Relationships Among Secondary Traumatic Stress, Coping, And Years Of Service In Firefighter/Emergency Medical Service Personnel, Lynne S. Sanders

Faculty Dissertations

The purpose of this study is to examine relationships among stress, coping, and years of service in rescue personnel. One hundred sixteen voluntary subjects employed in Fire/EMS service in a small southern city participated in the study. Subjects completed a demographic questionnaire, The Davidson Trauma Scale (DTS), and The Coping Inventory for Stressful Situations (CISS).

The incidence of symptomatic stress for the sample was 19.8 percent, higher than the general population but comparable to rates found in other studies of rescue workers. Calls involving children were rated as most disturbing by the subjects. There was no relationship found between years …

Context Effects In Visual Length Perception: Role Of Ocular, Retinal, And Spatial Location, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

In three experiments, we examined the transfer of orientation-contingent context effects between the eyes and across portions of the retina with or without variation in external spatial location. Previous research had shown that vertical lines are judged long, relative to horizontal lines, when the stimulus set comprises relatively long horizontals and short verticals (Contextual Condition B), as compared with the reverse when the stimulus set comprises relatively short horizontals and long verticals (Contextual Condition A). Consequently, the contextual set of stimuli influences the magnitude of the horizontal-vertical illusion (HVI), decreasing its size under Contextual Condition A and increasing its size …

Psychosocial Correlates Of Physical Activity And Sedentary Leisure Habits In Young Adolescents: The Teens Eating For Energy And Nutrition At School Study, Amanda Birnbaum, Kathryn H. Schmitz, Leslie Lytle, Glenn A. Phillips, David M. Murray, Martha Y. Kubik

Department of Public Health Scholarship and Creative Works

BACKGROUND: Low levels of physical activity (PA) and highly sedentary leisure habits (SLH) in youth may establish behavioral patterns that will predispose youth to increased chronic disease risk in adulthood. The purpose of this paper was to examine associations of demographic and psychosocial factors with self-reported PA and SLH in young adolescents. METHODS: A general linear mixed model predicted self-reported PA and SLH in the spring from demographic and psychosocial variables measured the previous fall in 3798 seventh grade students. RESULTS: PA and SLH differed by race, with Caucasian students reporting among the highest PA and lowest SLH. Perceptions of …

Physician-Related Determinants Of Cervical Cancer Screening Among Caribbean Women In Toronto, Ilene Hyman, Punam Mony Singh, Marta Meana, Usha George, Lilian M. Wells, Donna E. Stewart

Psychology Faculty Research

BACKGROUND: Minority women in Canada are less likely to be screened for cervical cancer than their counterparts in the general population, despite the fact that the proportion of these women who consult a general practitioner about their health each year is similar to minority women. This study examined the physician and practice characteristics associated with Pap testing and perceived barriers to Pap testing of family physicians serving the Caribbean community of Toronto.

METHODS: A mail-back questionnaire was sent to Toronto family physicians practicing in neighborhoods with a high proportion of Caribbean Canadians.

RESULTS: Although 79.7% of the 64 participating physicians …

Reactive Attachment Disorder : Diagnosis, Assessment, And Treatment, Kimberly A. Rees

Graduate Research Papers

In recent years, there has been an increasing trend toward the use of Reactive Attachment Disorder (RAD) as a diagnosis to describe myriad problem behaviors and disturbed interactions between infants, young children and their caregivers. There is considerable disagreement about what RAD actually entails and, in particular, what types of assessments and treatment interventions to use with affected children and families (Hanson & Spratt, 2000). This paper is intended to clarify what the current research states about Reactive Attachment Disorder. It includes the definitions and diagnosis, importance of attachment, biological components, risk factors later in life, assessment, and treatment available …

Attachment Disorders And Personality Disorders : A Possible Connection, Jen Sacora

Graduate Research Papers

Researchers now propose that attachment theory can be applied beyond childhood. They believe attachment exists in adulthood and influences adult relationships. Possible connections between personality disorders and well-known approaches to personality development such as attachment theory have been made (Brennan & Shaver, 1998).

The purpose of this paper is to examine the relationships between parent-infant attachment which influence adult relationships and psychopathology. Theories of personality development as they relate to attachment will be explored as well as influence of early childhood experiences on personality. Finally, possible connections between attachment disorders and personality disorders will be speculated.

On The Evolution Of Depression, Mike W. Martin

Philosophy Faculty Articles and Research

In "Depression as a Mind-Body Problem," Walter Glannon outlines a psychosocial-physiological explanation of depression as a psychological response to chronic stress—today, especially social stress—in which cortisol imbalances disrupt neurotransmitters. Accordingly, treatment for depression should combine psychopharmacology and psychotherapy—a valuable reminder in light of the current restrictions on funding for health care (Hobson and Leonard 2001). My comments focus, however, on Glannon's objections to evolutionary theorists who explain our capacity for depression as adaptive to the natural and social environment. His objections are implausible because he fails to distinguish depression as a mood and a disorder.

Issues Impacting The Quality Of Mental Health In Older Adults, Rachel I. Pettit

Graduate Research Papers

Older adults are confronted with a variety of developmental and unexpected issues that can impair or strengthen their mental health. Affective and anxiety disorders, substance abuse, and suicide are some of the mental health issues when older adults experience difficulty with the aging process. On the other hand, the quality of their physical and mental health, their support system, the resolution of grief and loss issues, and the strength of their spirituality assist older adults in recreating meaning. Thus, they are able to live their senior years with purpose. These issues will be addressed and recommendations will be described with …

Adaptive Functions Of The Corpus Striatum: The Past And Future Of The R-Complex, Neil Greenberg

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

The basal ganglia is emerging from the shadow cast by the most conspicuous clinical expression of its dysfunction: motor disorders.What is revealed is the nexus of a widely distributed system which functions in integrating action with cognition, motivation, and affect. Prominent among non-motor functions are striatal involvement in building up of sequences of behavior into meaningful, goal-directed patterns and repertoires and the selection of appropriate learned or innate sequences in concert with their possible predictive control. Further, striatum seems involved in declarative and strategic memory (involving intentional recollection and the management of retrieved memories, respectively). Findings from reptile experiments indicate …

Ethological Aspects Of Stress In A Model Lizard, Anolis Carolinensis, Neil Greenberg

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

Research on the stress response in reptiles can provide a useful comparative perspective for understanding how the constituent elements of the response can be put into service of diverse behavioral adaptations. A summary of the neural and endocrine causes and consequences of specific behavioral patterns seen in the small diurnal lizard, Anolis carolinensis, has provided a model for the exploration of the dynamics of autonomic and neurohormonal contributions to adaptive behavior.

In this species, changes in body color provide indices of the flux of circulating stress relevant hormones, and are seen in situations from spontaneous exploration through agonistic behavior. Furthermore, …

The Importance Of Behavioral Interventions And Stimulant Medication Effects On Reducing Attention Deficit Hyperactivity Disorder, Elizabeth Alvarez

Graduate Research Papers

Overall, various avenues of research state that ADHD is a complex disorder that requires treatment by multiple modalities. Most research states that a combination of medication and behavior therapy is necessary to resolve the symptoms. It should be noted that the dose of stimulant medication prescribed to a child with ADHD should be adjusted based on the child's response to a behavioral intervention, as well as the combination of the behavioral and pharmacological treatments. Rapport et al. (1982), as well as others, have found that medication alone will not "cure" ADHD. But with multiple methods of treatment the symptoms will …
