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 …

On Joel Weishaus' Forest Park: A Journal, Rania Masri

Reconstruction: Studies in Contemporary Culture

[First paragraph]

How do we define place? How do we develop our sense of identity and how do we recognize that development? With our constantly changing locations and with our locations themselves constantly changing into more urbanized areas, how do we locate and understand ourselves within our idea of place? How does our relationship with 'nature' touch our lives? In essence, how do we live, with - and within - ourselves?

The Edge Of The World, Joy Kennedy

Reconstruction: Studies in Contemporary Culture

“The Edge of the World” tells a true story of a mapping expedition in the second longest cave in Texas. When her survey group becomes lost inside the cave, the author uses the experience to propel questions of the duplicity of maps and the ambiguities of human perception. Detailed are the gritty nuances of caving that the average tourist never experiences: the tightness of squeezes, digging for air flow, and pushing for passages. The author finally questions if the blank spaces on maps should really be filled in with new discoveries, for perhaps something is being lost in the process.

Addressing Religion And Spirituality In Psychotherapy: Clients' Perspectives, Sarah Knox, Lynn A. Catlin, Margaret Casper, Lewis Z. Schlosser

College of Education Faculty Research and Publications

Twelve adult clients described the role of religion and spirituality in their lives and in therapy as a whole, as well as their specific experiences of discussing religious-spiritual topics in individual outpatient psychotherapy with nonreligiously affiliated therapists. Data were analyzed using Consensual Qualitative Research (CQR; Hill, Thompson, & Williams, 1997). Results indicated that clients were regularly involved in religious-spiritual activities, usually did not know the religious-spiritual orientation of their therapists, but often found them open to such discussions. Specific helpful discussions of religion-spirituality were often begun by clients in the 1st year of therapy, were related to clients' presenting concerns, …

Memory Enhancement By A Semantically Unrelated Emotional Arousal Source Induced After Learning, Kristy A. Nielson, Douglas Yee, Kirk I. Erickson

Psychology Faculty Research and Publications

It has been well established that moderate physiological or emotional arousal modulates memory. However, there is some controversy about whether the source of arousal must be semantically related to the information to be remembered. To test this idea, 35 healthy young adult participants learned a list of common nouns and afterward viewed a semantically unrelated, neutral or emotionally arousing videotape. The tape was shown after learning to prevent arousal effects on encoding or attention, instead influencing memory consolidation. Heart rate increase was significantly greater in the arousal group, and negative affect was significantly less reported in the non-arousal group after …

The Effects Of Non-Contingent Extrinsic And Intrinsic Rewards On Memory Consolidation, Kristy A. Nielson, Ted Bryant

Psychology Faculty Research and Publications

Emotional and arousing treatments given shortly after learning enhance delayed memory retrieval in animal and human studies. Positive affect and reward induced prior to a variety of cognitive tasks enhance performance, but their ability to affect memory consolidation has not been investigated before. Therefore, we investigated the effects of a small, non-contingent, intrinsic or extrinsic reward on delayed memory retrieval. Participants (n = 108) studied and recalled a list of 30 affectively neutral, imageable nouns. Experimental groups were then given either an intrinsic reward (e.g., praise) or an extrinsic reward (e.g., $1). After a one-week delay, participants’ retrieval performance …

Theta Activity During Navigation In Virtual Environments, Colleen Margaret Moore

Psychology Theses & Dissertations

Human navigation has gone through many different stages, from guidance by stars to guidance by technology. Theories for performance differences range from differences between individuals, to experience with the environment. Researchers turn to virtual environments during experimentation which are easy to manipulate and easier to measure during navigation. However, fidelity is an issue with regard to transfer of learning to a real world environment. We examined differences in theta activity during navigation in low and high fidelity virtual environments. The researchers recruited thirty-two students between the ages of 18-40 from the university subject pool for voluntary participation. We measured EEG …

An Evaluation Of A Service-Learning Approach To Assist In Achieving The Goals Of A Comprehensive Guidance Program, Kathryn Ann Stott

Theses and Dissertations

The purpose of this qualitative study was twofold: (a) to investigate how a service-learning class assisted in achieving the goals of a comprehensive guidance and development program in a junior high school, and (b) to examine the effects of a service-learning class on junior high school students. Thirty students who had been in the service-learning class participated in semi-structured interviews. Parents and teachers were also interviewed to cross-validate student perceptions. Interviews were transcribed and analyzed to identify core meanings. Using phenomenological analysis, eight major themes were identified: personal awareness, social skills development, learning skills, career interests, character education, application of …

An Assessment Of An Education Package Intervention Targeting The Appropriate Reporting Of Suspected Child Abuse, Clinton K. Wirtz

Masters Theses

The proper reporting of suspected child abuse and neglect continues to be a concern despite laws requiring professionals working with children to report any suspicion of child abuse or neglect to Children's Protective Services (CPS). This study assesses the efficacy of an education intervention versus the Michigan Child Protection Law (CPL) using 29 undergraduate child psychology students. Videotaped scenarios of simulated child interviews were used in a pretest/posttest between-groups design. Child physical abuse was the focus of the study. The results of the student participants' decisions regarding the videotaped scenarios were compared to the results of 10 CPS employees having …

Development Of An Analogue Of A Response-Class Hierarchy, Daniel B. Shabani

Dissertations

Within the operant conditioning literature, there exists the concept of the functional response class. A functional response class is defined as a collection of responses that all produce the same outcome. If the members of a response class occur in a predictable order, a response-class hierarchy is said to exist. A hierarchy refers to a specific type of response class in which each member of the response class may be temporally determined along various dimensions (e.g., response effort, immediacy of reinforcement, magnitude of reinforcer). The response-class hierarchy has received relatively little conceptual attention over the years and, not surprisingly, there …

The Effects Of Dextromethorphan On Response Acquisition With Delayed Reinforcement, Thomas B. Morgan

Dissertations

The current study examined in 2-h sessions the effects of intraperitoneal injections of dextromethorphan (DM) (0.0, 40.0, 60.0, and 80.0 mg/kg) on the acquisition of lever-press responding in rats that were exposed to a two-lever procedure in which responses on the reinforcement lever (RL) were reinforced with food after a 15-s resetting delay and responses on the cancellation lever cancelled a scheduled reinforcer. Response acquisition was observed at all drug doses. A decrease in RL responses, food deliveries, and the number of subjects that acquired responding was observed at the highest dose of DM. All doses of DM increased latency …

Humane Education: The Effects Of Animals In The Classroom On Children's Empathy In Japanese Elementary Schools, Mika Maruyama

Dissertations and Theses

Although humane education, promoting children's kindness toward animals, has been evaluated as a factor influencing children's kindness toward humans later in their life, the effect of a classroom pet hasn't been well studied. The current study investigated the influence of intensified daily interactions with living animals in the classroom on the development of empathy among Japanese children. Specifically, the study examined (a) the effect of introducing animals into the classroom on children's empathic behaviors and attitudes, and (b) the generalization of this animal-directed empathy to humans.

Chronic Olanzapine Treatment Eliminates Cognitive Deficits Produced By Neonatal Quinpirole Treatment., Stephanie K. Thacker

Electronic Theses and Dissertations

This study evaluated the effects of chronic olanzapine treatment on cognitive performance and neurochemical function in a rodent model of schizophrenia. Animals were neonatally treated with quinpirole, a dopamine D₂ receptor agonist, or saline. Quinpirole treatment produces an increase of dopamine D₂ receptor sensitivity that extends into adulthood, known as D₂ receptor priming, similar to a phenomenon that occurs in schizophrenia. These same rats were treated in adulthood for 28 days with olanzapine, an atypical antipsychotic, or saline. Dopamine D₂- primed rats demonstrated significant deficits on a cognitive task that were alleviated by olanzapine treatment. …

Number Comprehension By A Grey Parrot (Psittacus Erithacus), Including A Zero-Like Concept, Irene M. Pepperberg, Jesse D. Gordon

Sentience Collection

A Grey parrot (Psittacus erithacus) that was able to quantify 6 item sets (including subsets of heterogeneous groups, e.g., blue blocks within groupings of blue and green blocks and balls) using English labels (I. M. Pepperberg, 1994a) was tested on comprehension of these labels, which is crucial for numerical competence (K. C. Fuson, 1988). He was, without training, asked “What color/object [number]?” for collections of various simultaneously presented quantities (e.g., subsets of 4, 5, and 6 blocks of 3 different colors; subsets of 2, 4, and 6 keys, corks, and sticks). Accuracy was greater than 80% and was unaffected by …

The Effects Of Core Affect, Emotion, And Self-Efficacy On Physiologic Response To Social Stressors, Jessica L. Reedy

Renée Crown University Honors Thesis Projects - All

Cardiovascular health is affected by many factors including biological aspects such as heredity and overall health, as well as by environmental factors. Social stress, socioeconomic status, family environment, and coping skills have all been shown to contribute increased risk for cardiovascular disease. In an effort to further elucidate past findings in this area, this study, conducted on 36 college-age students, examined the connection between physiological response (blood pressure, heart rate, and mean arterial pressure) to laboratory social stressors in correspondence to emotional, affective, and arousal levels, as measured by self-report. The results yielded a significant relationship between physiologic response to …

The Effects Of The Availability Heuristic On Student's Judgments Of Others Alcohol Consumption, Jennifer Mcenroy

Renée Crown University Honors Thesis Projects - All

The primary purpose of this study was to test the hypothesis that enhancing the availability of images that either portrayed liberal heavy drinking at college or the conservative academic side of college would serve to influence students’ perceptions of peer norms. It was hypothesized that students would rely on the availability heuristic to make judgments of peer norms, so that exposure to a movie clip that emphasized drinking would increase estimates of peer drinking norms when compared with exposure to a movie clip that emphasized academic work. It was further hypothesized that the film clips would assist participants in making …

Play Assessment: The Effects Of Peer Interaction On Children's Cognitive Capabilities., Korrinda Mendez

Student Work

Play Assessment (PA) has recently gained the attention of researchers as a potential valid assessment tool for determining the cognitive capabilities in younger children. O f particular importance is the use o f PA among various contexts. Specifically, PA can provide insight into the types of contextual situations that promote higher levels of cognitive skills in younger children. The present study explored peer interactions as a contextual aspect of PA using the PACSS empirical coding scheme to determine the highest level of play behavior. According to the present study, results did not yield any significant differences in overall cognitive play …

Instinct And Second-Guessing Oneself On Tests, Bethany Bennett, Nicole Lafser

Undergraduate Psychology Research Methods Journal

When taking exams, students may find themselves deciding between the answer that first comes to mind, and a second logical answer. When given the option to record both first instinct and second-guess answers, are students able to answer correctly more on their first or second try? Furthermore, do those students who tend to answer correctly on their second try have lower grade point averages? If so, this would indicate that when taking tests, they have not been able to fully represent their knowledge. In the present study, 16 participants read an informative passage and completed a series of ten open-ended …

K-Means Clustering With Multiresolution Peak Detection, Guanshan Yu, Leen-Kiat Soh, Alan B. Bond

Avian Cognition Papers

Clustering is a practical data mining approach of pattern detection. Because of the sensitivity of initial conditions, k-means clustering often suffers from low clustering performance. We present a procedure to refine initial conditions of k-means clustering by analyzing density distributions of a data set before estimating the number of clusters k necessary for the data set, as well as the positions of the initial centroids of the clusters. We demonstrate that this approach indeed improves the accuracy and performance of k-means clustering measured by average intra to interclustering error ratio. This method is applied to the virtual ecology project to …

Resistance To Change Of Ethanol Self-Administration: Effects Of Naltrexone And Extinction, Corina Jimenez-Gomez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Drug self-administration has proven to be an adequate model for assessing variables that contribute to the maintenance of drug taking. The present experiment was concerned with the persistence of drug self-administration, a defining characteristic of drug dependence and abuse. Findings from studies of the resistance to change of food-maintained responding may contribute to a better understanding of the persistence of drug abuse and dependence. Using an animal model of alcohol self-administration, this study evaluated the effects of rate of reinforcement on the persistence of ethanol self-administration in rats in the face of behavioral (i.e., extinction) and pharmacological (i.e., naltrexone) disruptors. …

The Effects Of Morphine On The Discrimination Of Subject-Produced And Experimenter-Imposed Durations, Ryan D. Ward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Experiments on the effects of drugs on behavior maintained by temporal-discrimination procedures have led to discrepant results. Recent experiments suggest that the effects of drugs may differ depending on whether the subject is timing some aspect of its own behavior or some other stimulus. The present experiment used a multiple-schedule procedure composed of a subject-produced and experimenter-imposed component. In the subject-produced component, pigeons categorized the duration of their most recently emitted interresponse time. In the experimenter-imposed component, pigeons categorized the duration of a key light. Morphine generally produced underestimation of time during the subject-produced component, a result in agreement with …

The Effects Of Added Reinforcers On Resistance To Change, Christopher A. Podlesnik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The fundamental unit of behavior, defined by the discriminated operant, can be reduced to the three-term contingency, which includes an antecedent stimulus, a response, and a reinforcing consequence. Behavioral momentum theory suggests that resistance to disruption (i.e., resistance to change) of operant behavior is governed by the relation between the antecedent stimulus context and the rate of reinforcement within that context (i.e., Pavlovian stimulus-reinforcer relation). Further, behavior momentum theory suggests that resistance to change is independent of the contingency between the response and the reinforcer (i.e., operant response-reinforcer relation). Thus, although additional response-independent food decreases response rates by greatly degrading …

Color And Depression In The Diagnostic Drawing Series, Cara Emily Levitt

EVMS School of Health Professions Theses & Dissertations

One of the most interesting and widely held assumptions by clinicians who used projective drawings was that the absence of color may indicate depression. The research about color’s relationship to depression was ambiguous, limited and dated. In this study it was hypothesized that the absence or presence of color in the Feeling Drawing of the Diagnostic Drawing Series [DDS] will have a positive correlation with a diagnosis of Major Depression. To test this hypothesis the colors both in the DDS archives Major Depression group and comparison group were counted and then statistically analyze to determine if specified colors were present …

Glutamate Receptors In Perirhinal Cortex Mediate Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

Object recognition is consistently impaired in human amnesia and animal models thereof. Results from subjects with permanent brain damage have revealed the importance of the perirhinal cortex to object recognition memory. Here, we report evidence from rats for interdependent but distinct stages in object recognition memory (encoding, retrieval, and consolidation), which require glutamate receptor activity within perirhinal cortex. Transient blockade of AMPA receptor-mediated synaptic transmission within perirhinal cortex disrupted encoding for short- and long-term memory as well as retrieval and consolidation. In contrast, transient NMDA receptor blockade during encoding affected only long-term object recognition memory; NMDA receptor activity was also …

The Neural Substrates Of Infant Sleep In Rats, Karl Æ. Karlsson, Andrew J. Gall, Ethan J. Mohns, Adele M. H. Seelke, Mark S. Blumberg

Faculty Publications

Sleep is a poorly understood behavior that predominates during infancy but is studied almost exclusively in adults. One perceived impediment to investigations of sleep early in ontogeny is the absence of state-dependent neocortical activity. Nonetheless, in infant rats, sleep is reliably characterized by the presence of tonic (i.e., muscle atonia) and phasic (i.e., myoclonic twitching) components; the neural circuitry underlying these components, however, is unknown. Recently, we described a medullary inhibitory area (MIA) in week-old rats that is necessary but not sufficient for the normal expression of atonia. Here we report that the infant MIA receives projections from areas containing …

Sleep Habits And Patterns Of College Students And Their Relationship To Selected Personality Characteristics, Steve M. Jenkins

Doctoral Dissertations

College is a time of adjustment when many students have a newfound responsibility for many aspects of their lives, including sleep habits and patterns. College students often have sleep schedules that vary greatly, which can result in sleep disturbances. Previous research indicates that college students report significantly more sleep disturbances than the general population. Poor sleep quality has been linked to myriad psychological, physiological, and cognitive difficulties, including mood and anxiety disorders, cardiovascular disease, and poor academic performance. Oftentimes, sleep disturbances can be corrected with basic psychological interventions. Considering the deleterious effects that poor sleep can have on college students, …

The Three-Contingency Model Of Self-Management, Holly C. Harrison

Dissertations

The goal of this dissertation is to evaluate people's needs for self-management and the effectiveness of their use of the three-contingency model of self-management. This model prescribes a set of self-management procedures that can be applied to self-manage virtually any behavior. College students used these procedures to manage their own behavior as part of an extended psychology-course assignment.

This evaluation began with the Procrastination Survey, the results of which assessed the frequency of the students' self-management problems. The self-management interventions of up to 168 students were then evaluated using their self-reported performance data and an anonymous survey. The performance data …
