The Effects Of Acute Nicotine Abstinence On Vigilance And Verbal Memory In Non-Diagnosed Smokers, David W. Ayer

Dissertations

Research has shown a differential prevalence of smoking in the schizophrenic population compared to other psychiatric and non-diagnosed populations. The three most commonly investigated reasons for this differential prevalence in schizophrenics are: the self-medication hypothesis, side effects hypothesis, and sociological hypothesis. The self-medication hypothesis which proposes that schizophrenics smoke at a higher rate to ameliorate cognitive deficits is the most substantiated by the research. Of current interest is the possible role of nicotine in improving performance on vigilance and verbal memory, the two areas shown to be most related to impaired social functioning in schizophrenics. It is difficult to make …

Quantifying The Cognitive, Symptomatic And Neuroendocrine Impact Of The Coriolis Illusion; A Countermeasure For Motion Sickness, Catherine Grandizio

Master's Theses - Daytona Beach

When pilots are unable to accurately perceive the position and motion of their bodies, they are spatially disoriented. Spatial disorientation is often induced by aviation illusions, and its consequences include dizziness, confusion, nausea and fatigue. The present research evaluated the severity of cognitive, neuroendocrine and subjective symptoms of the Coriolis illusion, induced by a spatial disorientation flight training device. Also, the research examined the effectiveness of a mild, ground-based countermeasure, similar to the Coriolis illusion, in reducing the occurrence and severity of symptoms. In the early stages of data analysis, there appeared to be a significant impact of the Coriolis …

Effects Of Age On Contextually Mediated Associations In Paired Associate Learning, Jennifer Patricia Provyn

Psychology - Theses

Older adults demonstrate an associative memory deficit that has been attributed to difficulty binding item information to contextual information (Naveh-Benjamin, 2000). Accounts of temporally-defined episodic associations that depend upon contextual retrieval (TCM Howard & Kahana, 2002) predict that a deficit in item-to-context binding will result in fewer backward (b-a) and transitive (a-c) associations. To measure group differences in backward and transitive associations, younger and older participants learned single function lists of paired associates with no contextual overlap (e.g., j-k, l-m) and double-function lists of paired associates consisting of chains of pairs (e.g., a-b, b-c). Although younger adults out-performed older adults …

Perceived Desirability Of Given Names: Identifying A Relationship Between Given Names And Associated Personality Traits, Ellen D. Parks

Undergraduate Theses and Capstone Projects

This study was designed to determine whether participants would have better recall for names with phonetic properties that matched a paired personality trait. In other words, phonetically attractive names paired with positive traits and phonetically unattractive names paired with negative traits should have higher rates of recall than names whose phonetic properties did not match a paired personality trait, such as phonetically attractive names paired with negative traits or phonetically unattractive names paired with positive traits. Given names were deemed to be phonetically attractive or unattractive based on the number of sonorants (soft consonant sounds such as l, m, n, …

Spatial Learning Deficit In The Hiv-1 Transgenic Rat: Discerning Place From Strategy Learning, Abigail Lashomb

Seton Hall University Dissertations and Theses (ETDs)

HIV -1 infection is associated with a constellation of cognitive and motor deficits collectively termed HIV associated dementia. With the onset of HAART treatment, these cognitive effects have become more mild, but also more prevalent. The lack of a proper animal model to study these cognitive effects of HIV has lead to the development of a new transgenic rat. This rat expresses the HIV -1 genome with functional tat and gp 120 viral proteins. These proteins are linked with direct neural toxicity as well as the induction of cytokines and other indirect means of neuronal damage. As part of the …

Empathy And Cognitive Flexibility As Correlates Of Forgiveness, Rebecca Bennett Katovsich

Dissertations

Problem. For the past three decades, there has been a growing body of literature related to the topic of forgiveness. The idea that empathy, consisting of both emotional and cognitive aspects, plays an integral role in the process of forgiveness is widely supported in the literature, although there is limited empirical evidence for this claim. Beyond interest in examining the relationship between forgiveness and empathy, this research also aimed to explore the role of cognitive flexibility in the forgivenessprocess, considering both the intrapersonal and interpersonal dimensions of cognitive flexibility.

Method. The Enright Forgiveness Inventory, Interpersonal Reactivity Index, and the NEO …

The Effect Of Massed And Spaced Presentation And Practice On Repetition Priming, Catherine Mcneilly

Theses : Honours

This review examines the current literature with regard to repetition priming and practice. The empirical research and theoretical accounts of repetition priming reviewed indicate that repetition priming increases with practice. The review also indicates that an effect for the type of presentation of the stimuli during an experiment exists and that this effect may moderate the influence of practice on repetition priming. The variations in experimental design between studies are discussed, providing a possible explanation for contrasting findings within repetition priming research. Further research is identified and discussed. The aim of this study was to investigate the effect of Massed …

An Investigation Of The Relationship Between Inhibitory Motor Control And Low And High Trait Impulsivity In Non-Clinical Adults, Lindsay Vibert

Theses : Honours

Impulsivity is generally thought to refer to rapid, spontaneous and inappropriate behaviour. One causal view of impulsivity is that of executive inhibitory dyscontrol. Inhibitory control requires the suppression of an implicit or explicit response and may be assessed with laboratory behavioural tasks. Executive inhibition includes cognitive inhibition, interference control and behavioural inhibition. Impulsivity is frequently measured using self-report personality-based inventories. Investigations of the relationship between inhibitory control and impulsivity are uncommon. It is further proposed that there is a significant inverse relationship between a self-report measure of impulsivity (the Barratt Impulsiveness Scale) (Patton, Stanford, & Barratt, 1995) and a behavioural …

Exploring The Relationship Between Selfobject Needs And Parental Bonding, Sherry-Lee Smith

Theses : Honours

Self psychology proposes that the individual's early experience is central to adult psychological functioning. The purpose of this paper is to outline the key concepts in self psychology, the empirical evidence supporting it and how it relates to early parenting experiences. The enduring psychological nature of early interactions with an individual's parents, are discussed in relation to adult functioning. Self psychology is based on clinical observations of clients undertaking psychoanalysis. Empirical support for the model is limited. The majority of studies consider the concept of narcissism, and other related self psychological concepts, such as selfobject needs, are inadequate Although this …

Hemispheric Sensitivity To Thematic Role Information Derived From Active And Passive Verbs: An Event Related Brain Potentials Study, Christopher A. Schwint

Theses and Dissertations (Comprehensive)

Recent research examining differences in the way the left (LH) and right (RH) hemispheres of the brain process language have used the visual half-field (VHF) paradigm to examine whether each hemisphere can independently process information from sentences. The current study expanded upon such work by using event related brain potential (ERP) measures to examine how the comprehension of thematic role knowledge, a process essential to successful sentence comprehension (MacDonald, Pearlmutter, & Seidenbeerg, 1994), is undertaken in each hemisphere. During language comprehension, agents (entities that initiate action in an event) depicted by nouns (e.g., cop) have been shown to be associated …

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 …
