The Perceived Psychosocial Benefits Of Pet Ownership On Child Development: A Parental Perspective, Erin K. Leahy

Theses : Honours

The purpose of this review is to explore the beneficial role pets play in facilitating the psychosocial development of preadolescent children. It is proposed that the pet is perceived by both the child and parent as a developmental resource during preadolescent development, as it assists the child in accomplishing key developmental tasks such as responsibility and autonomy, socialisation and the development of humanistic qualities. This review also highlights the importance of pets in assisting preadolescents develop self esteem and identity, and examines how pets give children new perspective on important life matters such as birth, illness and death. Attainment of …

Repeat After Me: The Use Of Errorless Learning In The Foreign Language Classroom, Mark Adam Foster

Honors Program Theses

Errorless learning is one of these concepts. It is a technique that allows for efficient learning devoid of the frustrating process of making countless errors; something that is usually associated with the mastering of almost any topic. Errorless learning has proved beneficial to many specialized populations, yet has eluded implementation in a normal classroom setting. It seems especially well suited for use in foreign language classrooms. It has been noted that these classrooms often lack specialized teaching strategies, particularly in regards to vocabulary and pronunciation learning (Gonzalez-Bueno, 2001; Barcroft, 2004). Errorless learning is an effective teaching strategy, and could be …

Everybody's Doing It But Me: Comparing Pluralistic Ignorance Across Behaviors, Katherine S. Corker

Honors Program Theses

This study examined pluralistic ignorance (PI) for a variety of behaviors and attitudes such as health behaviors ( exercise frequency, fruits and vegetables consumed, personal hygiene, marijuana use), subjective well-being, and television habits. Student and nonstudent participants indicated their, their best friend's, the average student's, and the average American adult's attitudes on various topics (e.g., drugs, personal well-being; Prentice & Miller, 1993) and completed measures of alienation (Dean, 1961 ). Student and nonstudent populations showed PI; however, some items showed greater PI than others. High PI items tended to be health behaviors for the student sample and television habits for …

Exploring The Ligand Binding Site On The Dopamine Transporter By Photoaffinity Labeling And Site-Directed Mutagenesis, Maria Laura Parnas

Theses and Dissertations

The dopamine transporter (DAT) is a neuronal presynaptic transmembrane protein that clears released dopamine (DA) from the synaptic space, regulating the neurotransmitter concentration and availability, DAT and the related serotonin (SERT) and norepinephrine (NET) transporters belong to the SLC6 family of Na+ and CI- dependent symporters, and are major targets for the action of several drugs, including the psychostimulant cocaine. DAT is predicted to possess 12 transmembrane spanning domains (TMs), with both N- and C-termini located intracellularly. Extensive research efforts to gain insight on the molecular aspects of DAT have been attempted, but the three-dimensional arrangement of the protein as …

Instead Of Erklären And Verstehen: William James On Human Understanding, David E. Leary

Psychology Faculty Publications

Perhaps more than any other American psychologist and philosopher, William James (1842-1910) was intimately familiar with contemporary European thought and debate, including the discussion of Erklären and Verstehen advanced by Wilhelm Dilthey (1833-1911) and others around the turn of the twentieth century. Even before this discussion was initiated, James had been dealing with related issues, pondering alternative solutions, and formulating his own original views on human understanding. These views coalesced in a distinctive approach to cognition. Fundamental to this approach was a belief in possibility and probability as innate features of the physical as well as mental manifestations of the …

Applying The Appraisal Theory Of Emotionto Human-Agent Interaction, Aaron Pepe

Electronic Theses and Dissertations

Autonomous robots are increasingly being used in everyday life; cleaning our floors, entertaining us and supplementing soldiers in the battlefield. As emotion is a key ingredient in how we interact with others, it is important that our emotional interaction with these new entities be understood. This dissertation proposes using the appraisal theory of emotion (Roseman, Scherer, Schorr, & Johnstone, 2001) to investigate how we understand and evaluate situations involving this new breed of robot. This research involves two studies; in the first study an experimental method was used in which participants interacted with a live dog, a robotic dog or …

The Effect Of In-Vehicle Warning Systems On Driverresponse In Work Zones, James James Whitmire Ii

Electronic Theses and Dissertations

This research investigated the effectiveness of in-vehicle information technologies on driver behavior in work zones. In-vehicle information devices can increase driver awareness to an oncoming change in traffic flow and provide specific guidelines for driving speed requirements, lane merging strategies, or unexpected changes in the roadway (e.g., detours and lane shifts). The overall conditional effects for vehicle speed are significant; that is, both the audio and visual groups out performed the control group within the simulated work zone. Participants in audio group did outperform the visual group, not significantly though. The overall conditional effects for total time in violation are …

Individual Differences And The Impact Of Forward And Backward Causal Relations On The Online Processing Of Narratives, Stephen W. Briner, Christopher A. Kurby, Danielle S. Mcnamara

Psychology Faculty Publications

This paper investigated the impact of causality on reading time by examining the contributions of forward antecedent and backward consequence connections. Undergraduate students read four narrative texts, sentence by sentence. Reading times for each sentence were regressed onto the number of antecedents connecting forward to a sentence and backward to prior sentences. Overall, forward antecedents and backward consequences explained unique variance in reading times, with increases in antecedents and consequences predicting decreases in reading time. However, causal consequences did not contribute unique variance to participants with higher literature knowledge. Further, the presence of forward antecedents significantly attenuated reading time differences …

Observations Of Rough-Toothed Dolphins (Steno Bredanensis) Off The Coast Of Utila, Honduras, Stan A. Kuczaj Ii, Deirdre Yeater

Psychology Faculty Publications

Local dive shop operators and fishermen report that rough-toothed dolphins (Steno bredanensis) are frequently encountered off the coast of Utila, Honduras, (16°05'46.5"N 86°55'47.8"W). Our observations suggest that at least some of these animals may constitute a resident population, although the extent of the resident group’s home range has not been determined. Twenty-eight rough-toothed dolphins were identified using photoidentification techniques, 15 of which were re-sighted on two or more occasions. The 12 animals that were re-sighted four or more times were typically seen together, suggesting that they constitute a stable social group. At least one of these dolphins is …

Cognitive Mechanisms Of Memory Impairment Following Traumatic Brain Injury, Mark D. Whiting

Theses and Dissertations

Memory impairment is common following traumatic brain injury (TBI). In recent years, researchers have demonstrated that the processes underlying memory formation (working memory, encoding, consolidation, and retrieval) are interrelated but dissociable events.The following study was designed to determine how these processes contribute to memory impairment following experimental TBI in the rat. Experiment 1 indicated thatTBI induces severe working memory deficits in a delayed non-matching-to-place task.Although all animals displayed intact acquisition, only injured animals displayed poor performance as the delay between the sample and choice phases was increased.Experiment 2 was designed to determine if TBI produces a transient period of posttraumatic …

Do Multicultural Experiences Make People More Creative? If So, How?, Chi-Yue Chiu, Angela K. Y. Leung

Research Collection School of Social Sciences

MacDonalds' Rice-burger in Asia; Starbucks’ Coffee Mooncake in Singapore; Disneyland Yin-Yang Mickey Mouse Cookies in Hong Kong; Lay's Peking Duck Flavored Potato Clip … The list can go on. What is common in all these examples is that they are all novel product ideas created by integrating seemingly non-overlapping cultural or product ideas from Eastern and Western cultures. Combining seemingly non-overlapping ideas from different cultures is an example of creative conceptual expansion, a term in cognitive psychology that refers to the process of extending the conceptual boundaries of an existing concept by synthesizing it with other seemingly irrelevant concepts (Ward, …

Mate Preference Necessities In Long- And Short-Term Mating: People Prioritize In Themselves What Their Mates Prioritize In Them, Norman P. Li

Research Collection School of Social Sciences

People were given highly constrained low budgets of mate dollars to allocate across various characteristics pertaining to their ideal partners and to their ideal selves for long- and short-term mating. First, results replicated findings from LI et al. (2002) and LI and KENRICK (2006). For ideal long-term mates, men prioritized physical attractiveness and women prioritized social status. For ideal short-term mates, both sexes prioritized physical attractiveness. Second, people's design of their ideal selves mirrored what the opposite sex ideally desired in their mates. For a long-term mating context, men prioritized social status in themselves and women prioritized physical attractiveness in …

Joint Attention And Word Learning In Ngas-Speaking Toddlers In Nigeria, Jane B. Childers, J. Vaughan, D. A. Burquest

Psychology Faculty Research

This study examines infants’ joint attention behavior and language development in a rural village in Nigeria. Participants included eight younger (1;0 to 1;5, M age=1;2) and eight older toddlers (1;7 to 2;7, M age=2; 1). Joint attention behaviors in social interaction contexts were recorded and coded at two time points six months apart. Analyses revealed that these toddlers were producing more high-level joint attention behaviors than less complex behaviors. In addition, the quality and quantity of behaviors produced by these Nigerian children was similar to those found in other cultures. In analyses of children’s noun and verb comprehension and production …

Assessing The Format Of The Presentation Of Text In Developing A Reading Strategy Assessment Tool (R-Sat), Sara Gilliam, Joseph P. Magliano, Keith K. Millis, Irwin Levinstein, Chutima Boonthum

Computer Science Faculty Publications

We are constructing a new computerized test of reading comprehension called the Reading Strategy Assessment Tool (R-SAT). R-SAT elicits and analyzes verbal protocols that readers generate in response to questions as they read texts. We examined whether the amount of information available to the reader when reading and answering questions influenced the extent to which R-SAT accounts for comprehension. We found that R-SAT was most predictive of comprehension when the readers did not have access to the text as they answered questions.

The Effectiveness Of Rating Scales And Semi-Structured Interview In Diagnosing Adult Attention Deficit Hyperactivity Disorder, Carolyn Mae Cofrancesco

Dissertations

Problem and purpose. There are few standardized tools for diagnosing ADHD in adults. The purpose of this study was to compare a standardized rating scale (CAARS) used by different observers, with a comprehensive diagnostic interview (CAADID) with respect to their ability to diagnose subtypes of ADHD.

Method. Subjects for this study came from baseline data of 98 patients (18 to 60 years ofage) participating in a drug trial for adult ADHD. The CAADID interview results in a yes-no decision as to whether the patient meets DSM-IV criteria for the subtypes ADHD. A t -test was used to compare the CAADID-diagnosed …

Brain Integrity And Cerebral Atrophy In Vietnam Combat Veterans With And Without Posttraumatic Stress Disorder, Bruce L. Brown, Dawson W. Hedges, G. William Thatcher, Pamela J. Bennett, Shabnam Sood, David Paulson, Sarah Creem-Regehr, Steven Allen, Jamie Johnson, Brooke Froelich, Erin D. Bigler

Faculty Publications

Posttraumatic stress disorder (PTSD) is associated with decreased hippocampal volume, but the relationship between trauma and brain morphology in the absence of PTSD is less clear. In this study, measures of brain integrity were determined by estimating gray and white matter regional brain volumes using structural magnetic resonance imaging in six patients with PTSD and in five controls with comparable trauma exposure but without clinical evidence of PTSD. The only statistically significant volume difference between groups was observed multivariately in the white matter of the right temporal lobe (superior temporal gyrus, fusiform gyrus, parahippocampal gyrus, white-matter stem, middle temporal gyrus, …

Conditional Discrimination And Reversal In Amnesia Subsequent To Hypoxic Brain Injury Or Anterior Communicating Artery Aneurysm Rupture, C. E. Myers, J. Deluca, Ramona O. Hopkins, M. A. Gluck

Faculty Publications

Human anterograde amnesia can develop following bilateral damage to the hippocampus and medial temporal lobes, as in hypoxic brain injury, or following damage to the basal forebrain, as following anterior communicating artery (ACoA) aneurysm rupture. In both cases, the mnestic deficit may be similar when assessed by standard neuropsychological measures. However, animal and computational models suggest that there are qualitative differences in the pattern of impaired and spared memory abilities following damage to hippocampus versus basal forebrain. Here, we show such a dissociation in human amnesia using a single two-stage task, involving conditional discrimination and reversal. Consistent with a prior …

The Role And Meaning Of Spirituality Among Older Adults In Western Australia, Sue Grossman

Theses : Honours

Given the large projected increase in the proportion of Australian older adults (13% in 2004 to 22% in 2031) and the personal importance placed on spirituality in the lives of older adults, it is timely to investigate the role of spirituality in the everyday lives of older adults. The present paper analyses the literature pertaining to the psychological implications of spirituality in older adulthood. The points of discussion identified in the review include the relationship between spirituality and religion, theories of spiritual development, psychosocial wellbeing, health, end of life issues, culture, and psychological practice. It is concluded that the paucity …

Ethnocentrism And Attitudes To Cultural Diversity And Immigration: A Review ; Ethnocentrism And Attitudes To Cultural Diversity And Immigration In Western Australia, Sophie Mounsey

Theses : Honours

Increasing trends in immigration in the contemporary world have reaffirmed the importance of understanding intercultural relations within multifarious, plural societies. A research-based understanding of these societies is essential for their successful management. This review focuses upon how the construct of ethnocentrism and its composites are related to attitudes to immigration and diversity. Theoretical explanations of ethnocentrism and intergroup processes are provided, and ethnocentrism is discussed in relation to several precipitators and moderators of ethnocentric attitudes to immigration and diversity, including authoritarianism, social dominance, security, ethnic hierarchies, cultural distance, and social conditions. It is recommended that future research focuses on the …

The two attitude …

Aged Rats: Sex Differences And Responses To Chronic Stress, Rachel E. Bowman, Neil J. Maclusky, Samantha Diaz-Weinstein, Mark C. Zrull, Victoria N. Luine

Psychology Faculty Publications

Cognitive, as well as physiological, sex differences exist in young adult rats under both basal conditions and following chronic stress; however, few studies have examined whether sex differences remain in aged subjects and whether responses to stress are altered. We compared aged male and female Fischer 344 rats (21.5 months at testing) without stress and when given 21 days of restraint for 6 h/day on locomotion, anxiety-related behaviors, object recognition (non-spatial memory), object placement (spatial memory), body weight and serum steroid hormone levels. Control (unstressed) females had lower levels of estradiol and testosterone and higher corticosterone than males, and stress …

African American Children's Inferences Based On Race, Sex And Age, Erica Hightower

Masters Theses & Specialist Projects

Previous studies (Madole, Eastman, Stone, & White, 2005) have suggested that children do not make inferences about people on the basis of race until around 8 years of age. The present study was a replication of a study performed by Madole et al. The distinction between the two studies was in the sample used, hi the previous study the majority of children used were Caucasian. The present study sought to examine whether African American children were more likely to make inferences on the basis of race than Caucasian children. Children ages 6 to 11 years were asked to perform an …

Accelerating The Development Of Adaptive Thinking In United States Army Captains, Scott B. Shadrick

All-Inclusive List of Electronic Theses and Dissertations

The contemporary operational environment, the war on terrorism, and the Army transformation effort are requiring officers in the U.S. Army to exhibit high levels of adaptive performance. The Army recognized the need to develop adaptive leaders and developed the Think Like a Commander (Shadrick & Lussier, 2001) training program. Prior to this research no attempt has been made to establish the construct validity of the training program or to measure the levels of adaptive performance exhibited throughout an officer's career. The current research investigated the construct validity of the training program by examining the differences in adaptive thinking behaviors between …

Memory For Non-Focal Words, John Jones

Masters Theses & Specialist Projects

In two experiments a modified flanker paradigm was used to simultaneously present a focal word and an incidental non-focal word. The participants' task was to process the focal word in one of two conditions: naming aloud or a conceptual decision (concrete or abstract). The focal and non-focal words were either semantically related or not. Participants were instructed to direct their attention at the focal word.  Furthermore, the presentation of the focal word was brief to reduce the possibility of eye movement to the non-focal word. Memory was measured with implicit and explicit memory tests. Evidence was found to suggest implicit …

Comparative Perspectives On The Functions Of Sleep, John A. Lesku

All-Inclusive List of Electronic Theses and Dissertations

Previous comparative studies of sleep identified relationships between sleep and constitutive and ecological variables. Results from these studies helped shape early hypotheses for the function of sleep; however, all were conducted without an explicit phylogenetic or theoretic framework and focused exclusively on mammals. Hence, the validity of their results and applicability to other taxa is unclear. We ( 1) reviewed the literature on sleep in animals, (2) updated and reanalyzed the mammalian dataset using independent contrasts and (3) multivariate path analysis, and ( 4) presented the first quantitative analysis of sleep in a non-mammalian taxon: birds. Following previous mammalian analyses, …

Defining The Components Of Academic Self-Efficacy In Navajo American Indian High School Students, Thomas R. Golightly

Theses and Dissertations

The academic difficulties experienced by a majority of Navajo American Indian students are well documented. Past research has focused on a variety of internal and external factors which possibly explain some of these difficulties. Low levels of academic self-efficacy (ASE) has been identified as one of the factors possibly contributing to lower than expected rates of academic achievement and low post-secondary education retention rates in this population. This investigation sought to further define the component structures of ASE using theoretical structures postulated by Bandura (1977a, 1997), namely: past success, modeling, verbal persuasion, and emotional arousal. Information about grade point averages …

Assimilation And Contrast Effects In Cultural Frame Switching: Bicultural Identity Integration And Valence Of Cultural Cues, Chi-Ying Cheng, Fiona Lee, Veronica Benet-Martinez

Research Collection School of Social Sciences

This study examines how the valence of cultural cues in the environment moderates the way biculturals shift between multiple cultural identities. The authors found that when exposed to positive cultural cues, biculturals who perceive their cultural identities as compatible (high bicultural identity integration, or high BII) respond in culturally congruent ways, whereas biculturals who perceive their cultural identities as conflicting (low BII) respond in culturally incongruent ways. The opposite was true for negative cultural cues. These results show that both high and low BIIs can exhibit culturally congruent or incongruent behaviors, and have implications for understanding situations where high and …

Putting Humans First?, David Graham, Nathan Nobis

Attitudes Towards Animals Collection

In Putting Humans First: Why We Are Nature's Favorite, Tibor Machan argues against moral perspectives that require taking animals' interests seriously. He attempts to defend the status quo regarding routine, harmful uses of animals for food, fashion and experimentation. Graham and Nobis argue that Machan's work fails to resist pro-animal moral conclusions that are supported by a wide range of contemporary ethical arguments.

The Changing Concept Of Animal Sentience, Ian J. H. Duncan

Sentience Collection

A brief history of the concept of sentience is given. It is pointed out that the idea of sentience, at least in the mammals and birds, was accepted by lay people by the time of the Renaissance and before it was acknowledged by philosophers. It was not until the Enlightenment of the 18th century that philosophers started to accept the notion that animals have feelings. Towards the end of the 19th century, scientists and philosophers had developed a fairly sophisticated concept of sentience. Little consideration was given to sentience by scientists through much of the 20th century due to the …
