Expectations About Memory Change Across The Life Span Are Impacted By Aging Stereotypes., Tara T. Lineweaver, Andrea K. Berger, Christopher Hertzog

Scholarship and Professional Work - LAS

This study examined whether expectations about memory change with age vary for different personality types. Four adjectives from each of Hummert’s age-stereotype trait sets were selected to create 11 adjective clusters varying in both valence (positive versus negative) and relevance to memory functioning. Three hundred and seventy three participants in three age groups rated the memory abilities of target adults, defined by the adjective clusters, across the adult life span. Consistent with past studies, participants believed in age-related memory decline. However, participants rated target adults with positive personality traits as having better memory ability and less age-related memory decline than …

Cognitive Preference And Ethnic Identity Among Anglo And Native American High School Students, Chad Martin Novak

Walden Dissertations and Doctoral Studies

According to the Office of Educational Research and Improvement: A Project of the Stanford Institute for Higher Education Research, graduation rates for Native Americans from both secondary and post secondary institutions are dismally low at 58% and 7%, respectively. Some research addresses cognitive preference and other ethnic identity, but research animating the cognitive preference---ethnic identity interplay for high school students is absent. These limitations in access to educational opportunities lead to abbreviated quality life experiences and a restriction in individual efficacy and collective agency. The following project assessed ethnic identity using Phinney's Multigroup Ethnic Identity Measure and cognitive preference using …

Integrating Developmental And Free-Choice Learning Frameworks To Investigate Conceptual Change In Visitor Understanding, E Margaret Evans, Amy Spiegel, Wendy Gram, Judy Diamond

Department of Educational Psychology: Faculty Publications

Complex ideas like evolution—which run counter to common, but mistaken, intuitive knowledge like the 9-year-old’s quoted above—are challenging, both for exhibit developers and for the evaluation and research teams who assess the impact of exhibitions. It is always difficult to document measurable changes in deep conceptual understanding following a single visit to an exhibition (Allen, 2008, p. 58); Is this even possible with complex topics, such as evolution? In this article, we summarize a series of studies that may offer some help to exhibit developers and evaluators, as well as others who design and assess informal learning experiences. The studies …

The Representation Of Multiple Translations In Bilingual Memory : An Examination Of Lexical Organization For Concrete, Abstract, And Emotion Words In Spanish-English Bilinguals, Dana M. Basnight-Brown

Legacy Theses & Dissertations (2009 - 2024)

Tokowicz and Kroll (2007) originally reported that the number of translations a word has across languages influences the speed with which bilinguals translate concrete and abstract words from one language to another. The current work examines how the number of translations that characterize a word influences bilingual lexical organization and the processing of concrete, abstract and emotional stimuli. Experiment 1 examined whether the number-of-translations effect reported previously could be obtained in a different task (i.e., lexical decision task) using the same materials presented by Tokowicz and Kroll. Decision latencies revealed no significant differences between concrete and abstract words, which suggested …

The Neuroscientific Study Of The Self: Methodological And Theoretical Challenges, Cynthia J. Najdowski, Samuel E. Winer

Psychology Faculty Scholarship

Neuroscientific research methods, such as brain imaging techniques, have increasingly been applied to social cognitive research efforts and, in particular, to the study of the self. In this essay we discuss the ability of such research to shed light on the emergent, dynamic psychological phenomenon of self. Although neuroscientific tools can be useful for gaining general knowledge about associated underlying structures, a careful consideration of the methodological and theoretical issues discussed herein is necessary to avoid simplifying or reifying the self.

Examining Compressed Speech Listening Measure With College Students Who Are Visually Impaired Or Blind, William J. Marks

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychological assessments are a way of gaining some understanding of an individual in order to help make informed decisions (Sattler, 2001). These assessments offer potentially important and valuable information that can assist individuals with impaired vision in learning additional skills, improving deficient abilities, and in providing diagnostic information for future research. In addition, psychological assessments are frequently used to diagnosis a variety of psychological and learning disorders. Assessing individuals with impaired vision presents a variety of challenges from those encountered with the general population.

The current study provided an investigation into the relationship of the results of the compressed speech …

Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Danielle T. Bello

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder affects approximately 1% of the population. It is a severe and debilitating illness, causing serious impairment of interpersonal, occupational and social functioning. The disorder is characterized by marked mood swings as well significant neurocognitive deficits. Based on work with other psychiatric and neurological disorders, neurocognitive deficits in bipolar disorder are expected to be strong predictors of functional capacity. However, few studies have evaluated the consequences of neurocognitive deficits in this disorder. Most available studies have focused on the clinical correlates of functional outcome, such as number of hospitalizations, age of disorder onset, and severity of symptoms. While useful, …

Young Women's Perspectives On Tanning In Solariums: A Constructivist Grounded Theory Study, Michelle Louise Russell

Theses : Honours

Despite Australia's general public awareness regarding the dangers of UVR exposure, young women continue to tan in solariums. This study utilised a qualitative approach with eight in-depth interviews to explore young women's perspectives on tanning in solariums. The 'core category' or storyline underlying participants' responses was 'being in control'. Three core themes emerged from the data: 'positive reinforcers', which related to attractions and motivations to tan, 'possessing knowledge' which concerned the different types of knowledge which participants held, and 'change' which represented participants' outcomes from external pressures. It was found that body image concerns and reinforcing rewards were motivators to …

Reasons For Migration And Cultural Distance In South African Women's Migratory Adjustment Experiences: A Phenomenological Account, Ida Steyn

Theses : Honours

Researchers have identified migration to a new country as a stressful life event that is associated with loss of family, friends and community, and adjustment difficulties in the new country (Markovizky & Samid, 2008). In addition, involuntary migration and adaption to a new cultural environment is known to be a factor of psychological distress. Much is unknown about the adjustment of involuntary migrants during the critical period of reestablishment in the new environment. Moreover, less is known about transition processes between similar cultural contexts. It might be that transition is not as well supported when there is cultural similarity between …

Perceptions Of Disabled Workers' Transition From Worker Role To Retiree: Narrative Review; The Perceptions Of Ageing Disabled Workers Confronted With The Transition To Retirement, Naomi Goods

Theses : Honours

The disabled working population is ageing creating a need for transitional programs in supported employment. Limited research in this area makes it difficult to design programs which adequately address their needs which affects the quality of service provision. A review of Scopus, CINAHL, MEDLINE; Psyclnfo and ISI Web of Science databases was conducted. Outcomes of interest were studies looking specifically at perceptions of disabled workers in supported employment making the transition to retirement. Due to the dearth of information on this topic studies focusing on non-disabled populations or disabilities though injury or illness were included. Major findings suggest when workers …

Does A Sense Of Control Moderate Self-Regulation Strategies And Performance? When Feedback Lingers, Annette Feravich

Wayne State University Dissertations

ABSTRACT

This study examined whether a sense of control moderated the relationship between self-regulation and performance on an anagram task. High school students agreeing to participate in this study completed the Behavioral Inhibition/Behavioral Approach Scale (BIS/BAS) in order to determine individual promotion or prevention chronic self-regulatory strategies, as well as the revised Children's Attributional Style Questionnaire (CASQ-R) to determine a sense of control based on explanatory style. Changes in mood and performance on anagram tasks were measured at three different times during the study: prior to, after, and after discrediting randomly assigned negative or positive feedback. Performance tasks were designed …

Student Perceptions Of Streaming-Media Effectiveness, Sara Floyd Baber

Theses and Dissertations

The purpose of this mixed-methods study was to investigate cognitive-load theory as applied to the design of streaming media. In this study, student learning preferences and cognitive style were measured on a visualizer-verbalizer scale to determine the perceived importance of visual and audio components of streaming media used to supplement classroom instruction. Additionally, this study investigated cognitive-load theory by assessing attitudes regarding the importance of learner control when accessing streaming media files. The writer used 4 existing visualizer-verbalizer instruments in combination with 1 original survey that was designed to gather student perceptions and attitudes regarding the effectiveness of streaming media …

Social Construction Of Knowledge In A Semiformal, Long -Term Learning Environment: A Qualitative Study, Alycia Harris

Walden Dissertations and Doctoral Studies

Social learning plays a critical role in cognitive apprenticeship, community of practice, and knowledge production theories. Gunawardena's interaction analysis model, which provides a means of evaluating discourse for social construction of knowledge, is comprised of five phases: (a) sharing and comparing, (b) disagreement, (c) negotiation and co-construction of new knowledge, (d) testing of knew knowledge, and (e) use or phrasing of new knowledge. There is a paucity of research that has empirically explored social construction of knowledge, especially in an extended semiformal asynchronous graduate learning experience. This study explored two research questions: whether social construction of knowledge took place, and …

Event Syntax And Event Semantics As Constraints On Availability Of Discourse, Raymond B. Becker

Theses and Dissertations (Comprehensive)

The understanding of how temporal information constrains situation models is far from complete. In tehse two experiments participants read short stories, where the antecedent sentence was manipulated with respect to varying tense, grammatical and lexical verb aspect (Experiment 1), and then by varying grammatical and lexical verb aspect in conjunction with long and short duration events (Experiment 2). We used electrophysiological measures time-locked to the anaphoric referent to investigate how the brain responds to these temporal constraints. The purpose was to investigate teh possibility that these variables have an influence on the availability of discourse concepts in situation models. In …

An Exploratory Study On Reaction Time To Valenced Memories: The Importance Of Individual Differences, Emrah Ates

Theses : Honours

It is commonly accepted that valence has influences on long-term memory, but there are diverse results concerning methodology and the effect size. The literature is mixed with some authors reporting evidence consistent with negativity bias, others reporting evidence consistent with positivity bias and still others reporting no effect of valence on certain types of memory. This review argues that while there are divergent results for recall rate studies, reaction time studies and emotional Stroop task studies showed predominant negativity bias in long term memory. Moreover, many of the studies reviewed were solely concerned with group effects, rather than individual differences. …

Memory For Music And The Implications Of Expertise For Music Recall: A Review ; Memory For The Recall Of Popular Songs: A Comparative Study Of Musicians And Nonmusicians, Simon Maclachlan

Theses : Honours

How people remember music is not only a practical concern for musicians, it also poses an interesting challenge for psychological theory (Wallace, 1994). One question that has often been overlooked is what occurs during the time that elapses between the stimulus onset (hearing music) and the generation of a response (an indication that the song has been remembered). While there is evidence to show that memory for song may be biased in a forward direction (Sibma, 2003), the role of expertise on memory for song may provide a deeper understanding of the nature of our memory for music. This review …

An Exploration Of The Experiences Leading To Volunteer Facilitation Of Postnatal Depression Peer Support Groups, Tracey Parker

Theses : Honours

In recent years literature regarding peer support recovery services has been more prominent. However, little attention has been paid to how these services are used to treat postnatal depression and questions regarding what informs a consumer's decision to become a support person to others remain. The aim of this study was to explore women's postnatal depression and how their experience and recovery informed a decision to become a peer support group facilitator. Participants were eight women who were past or current facilitators with the Post Natal Depression Support Association Inc. (PNDSA). In-depth conversational style interviews were conducted with participants and …

The Relationship Between Working Memory Capacity And Movement Memory Of Dancers, Katrina Louise Muller-Townsend

Theses : Honours

Working memory capacity span tasks are suggested to predict complex cognitive behaviour across varied domains (Conway et al., 2005). However, it has been criticised that expert skills are highly situational and domain specific (Marteniuk, 1974). The current research aimed to investigate whether general memory span was related to movement span, and furthermore, whether this can predict dance learning. It was expected that memory for movement would be positively correlated with measures of working memory, due to the specific components of working memory, such as the capacity of the phonological loop. Furthermore, it was expected on the basis of previous research …

Adaptive Rationality: An Evolutionary Perspective On Cognitive Bias, Martie Haselton, Gregory A. Bryant, Andreas Wilke, David Frederick, Andrew Galperin, Willem E. Frankenhuis, Tyler Moore

Psychology Faculty Articles and Research

A casual look at the literature in social cognition reveals a vast collection of biases, errors, violations of rational choice, and failures to maximize utility. One is tempted to draw the conclusion that the human mind is woefully muddled. We present a three-category evolutionary taxonomy of evidence of biases: biases are (a) heuristics, (b) error management effects, or (c) experimental artifacts. We conclude that much of the research on cognitive biases can be profitably reframed and understood in evolutionary terms. An adaptationist perspective suggests that the mind is remarkably well designed for important problems of survival and reproduction, and not …

Cognitive Modeling Analysis Of Decision-Making Processes In Young Adults At-Risk And Not At-Risk For Alcohol Dependence, Lori Anne Wagner

Graduate Dissertations and Theses

This study used the Valence-Expectancy Learning model, a mathematical cognitive model, to dissect young adult performance on the Iowa Gambling Task (IGT). Drinking behavior and monetary incentive were examined as predictors of performance on the IGT. No differences were found among groups when data were analyzed using traditional behavioral analyses. However, when the Expectancy-Valence Learning model was applied to the data, differences between groups were found related to attention and choice consistency. Importantly, the cognitive model was not a good fit for fifty-seven percent of the data, meaning that it did not succeed in explaining how the participants' choices were …

Verhaltensdiagnostik Aus Der Perspektive Der Kognitiven Therapie Analyse Automatischer Gedanken Und Grundüberzeugungen (Behavioral Diagnostics From The View Of The Cognitive Therapy : Identification Of Automatic Thoughts And Attitudes)., Patrick Pössel, Martin Hautzinger

Faculty and Staff Scholarship

Die Veränderung von mit psychischen Problemen verbundenen negativen automatischen Gedanken und Grundüberzeugungen ist zentraler Bestandteil jeder Kognitiven Verhaltenstherapie. Daher ist die Aufdeckung dieser dem Bewusstsein oft nur wenig zugänglichen kognitiven Prozessen von entscheidender Bedeutung für den Erfolg einer Psychotherapie. Im vorliegenden Artikel werden neben dem ABCDE-Protokoll, welches die Standardmethode zur Identifikation und Veränderung negativer automatischer Gedanken ist, unterschiedliche Methoden zur Exploration von Grundüberzeugungen (Beispielsituationen sammeln, Imaginationsmethode, Pfeil-abwärts-Technik) detailliert dargestellt. Hierbei wird das eher induktive Vorgehen zur Aufdeckung von Grundüberzeugungen von Albert Ellis mit den mehr deduktiven Strategien von Aaron Beck und den Weiterentwicklungen von Judith Beck verglichen.

The Tactile Motion Aftereffect, Peggy Joanne Planetta

Theses and Dissertations (Comprehensive)

The tactile motion aftereffect (tMAE) is a perceptual phenomenon in which illusory motion is reported following adaptation to a unidirectionally moving tactile stimulus. Unlike its visual counterpart, relatively little is known about the tMAE. For that reason, the purpose of this dissertation was to gain a better understanding of the tMAE using both psychophysical and neuroimaging techniques. In a series of five experiments the skin was adapted using a plastic cylinder with a square-wave patterned surface. Chapter 2 consists of two experiments, both of which adapted the glabrous surface of the right hand. Experiment 1 showed that the prevalence, duration, …

Effects Of Concurrent Task Performance On Object Processing, Gabriela Durán

Open Access Theses & Dissertations

Most research on visual object identification focus on the bottom-up processes of the visual what? and where? pathways. However, such research has not been able to fully account for many visual abilities (e.g., identifying an object among many other objects and across changing conditions). Neurological evidence has shown that feedback from high-level areas (i.e., top-down processing) makes object processing more efficient. However, there are no behavioral studies that have tested this. Thus, four experiments used a concurrent n-back task to occupy higher-level areas and tested its effects on visual object processing relative to a number-repetition control task.

Experiment 1 examined …

Attention Allocation And The Variability Of The Stereotype Priming Effect, Katherine R. White

Open Access Theses & Dissertations

The stereotype priming effect is assumed to be a rather uniform and robust effect. However, a closer look at the existing literature suggests that the `standard' stereotype priming effect may be more susceptible to variability than originally believed. In the present study, we sought to demonstrate that the stereotype priming effect displays significant variability in strength depending upon the level of attention allocated to the stereotype feature of interest. Participants were assigned to 1 of 3 conditions: a lexical decision task (LDT) condition, a pre-primed LDT condition, and a gender categorization condition. It was predicted that the stereotype priming effect …

Holographic Leadership: Leading As A Way Of Being, Janet L. Byars

Antioch University Dissertations & Theses

Holographic Leadership integrates values-based leadership into an understanding of an energetic holographic world. It is a world where the unseen is the primary influencer, where the smaller is more powerful (Bohm, 1994). I will synthesize many diverse ideas into an exploratory theory that will suggest new insights into sustainable leadership. I will propose a new model of practice from which to work. I suggest that it is through an internal state of physiological coherence and psychological balance that a leader can truly learn to “hold steady” (Heifetz, 1994), creating an intentional holding environment, a coherent group dynamic, which draws forth …

A Study Of Possible Pre-Cognitive Advantages Of Bilingualism, Marisela Gutierrez

Open Access Theses & Dissertations

Past research has suggested that second language acquisition has a beneficial effect on the development of inhibitory control processes in children and adults. This has been referred to as the "bilingual advantage" and is most commonly quantified using the Simon task. Whether the bilingual advantage extends to precognitive mechanisms has not yet been examined. The goals of this study were to examine the bilingual advantage in university students; and to examine whether the bilingual advantage extends to the precognitive filtering mechanism of sensorimotor gating. It was predicted that, as compared to monolinguals, bilingual university students would have greater inhibitory control, …

Getting To Know You: The Effects Of Familiarity And Time On Social Perception, Clarissa Arms Chavez

Open Access Theses & Dissertations

A new direction in social perception research is developed. The present research explored the impact of familiarity and time on social perception processes based on cognitive neuroscience models, social categorization models, and memory consolidation constructs. Familiarity was manipulated within an exposure task and time was manipulated by testing participants both 2-6 hr and 48 hr after the exposure task. Experiment 1 investigated the influence of familiarity and time on the argument of the automaticity of social categorization and associated stereotypes by testing the argument with two separate tasks. Experiment 1a tested the influence of familiarity and time on associated stereotypes …

Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral

Open Access Theses & Dissertations

The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …

The Distinctiveness Effect In Fingerprint Identification: How The Role Of Distinctiveness, Information Loss, And Informational Bias Influence Fingerprint Identification, Jessica L. Marcon

Open Access Theses & Dissertations

Fingerprint misidentification has become a concern for legal professionals, especially after the high profile misidentification of Brandon Mayfield as the Madrid train bomber and the first fingerprint related DNA exoneration of Stephen Cowans. The current studies examined how humans perceive the distinctiveness of fingerprints, whether distinctiveness effects found in face perception research are evident in fingerprint identification, and whether there are conditions under which the distinctiveness effect can be eliminated. Experiment 1 examined the distinctiveness effect and information loss, while Experiment 2 investigated the distinctiveness effect and its interaction with information loss and informational bias. In Experiment 1, results showed …
