Performance Or Processing? Effects Of Levels Of Processing And Divided Attention On Memory-Related Eye Movements, Wei An

UNLV Theses, Dissertations, Professional Papers, and Capstones

Human memories are expressed either with or without consciousness, termed as explicit and implicit memories, respectively. Different encoding manipulations like levels of processing and divided attention have been shown to affect explicit memories but not implicit memories. These dissociations, however, were only found between explicit and implicit item memories. Whether explicit and implicit relational memories will exhibit similar dissociations is still unknown. In order to determine whether explicit and implicit relational memories dissociated in a similar way as explicit and implicit item memories, the levels of processing and divided attention were manipulated in the present study and participants' relational memories …

Influence Of Seductive Details, Belief-Congruence, And Repeated Testing On Memory For Controversial Information, Daniel Adam Nuccio

Theses and Dissertations

People often encounter conflicting information on a wide array of topics. How they evaluate this information in relation to their current beliefs, and the effects of other influences, such as the weight given to superficial aspects of the information (e.g. pictures, anecdotes, or jargon that are at most minimally related to an author's argument), has been of interest to researchers for many years. One component of their processing

and evaluation of this information is their memory for the information. This study set out to examine the following questions: (1) Is belief-congruent in

formation remembered better or worse than belief incongruent …

Examining The Effects Of Saccade Execution And Handedness On Proactive Interference., Montgomery A. Kroger

College of Arts & Sciences Senior Honors Theses

Proactive interference is the phenomenon by which previously-learned information impairs recall of more recently-learned information. The present experiment was conducted to investigate two factors that may affect the occurrence of proactive interference. The first of these factors is saccade execution. Saccade execution has been shown in numerous studies to improve performance on a wide range of memory tasks. The second factor was people’s consistency of handedness, a term referring to the strength of people’s tendency to use one hand (right or left) over the other. Although the results of the primary analyses were inconclusive, further exploration of the data led …

Chronic, Lethal Versus Acute, Non-Lethal Threats: A Look Inside The Memories Of Cancer Patients At The Time Of Their Diagnosis, Angeline M. Modesti

Undergraduate Honors Thesis Collection

Consequentiality, affect, and rehearsal are also important components that help contribute to the recall of autobiographical memories. Traditionally, these features have been assessed in public dramatic events in the past such as the Challenger explosion and the 9/11 terrorist attack. In opposition to these traditionally studied events, the present study examined the effects of these features on five different private events. An analysis of these different experiences was assessed to determine the role of consequentiality, affect, and rehearsal play on memory recall. These three components were assessed in five different events during different points of the lifetime. Adults diagnosed with …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

Changes In Cerebral White Matter, Vascular Risk And Cognition Across The Adult Lifespan, Andrew Robert Bender

Wayne State University Dissertations

Numerous studies over the past decade have used diffusion tensor imaging (DTI) to examine associations between age, diffusion and anisotropy measures of cerebral white matter (WM), and cognitive performance. However, few have examined relationships between intra-individual change in DTI measures of WM and cognitive function. It is possible that the extant cross-sectional findings are a poor representation of age-related change in WM and cognition. The present study used latent difference-score modeling (LDM) to assess change over two years in DTI indices fractional anisotropy (FA), radial diffusivity (DR), axial diffusivity (DA) and mean diffusivity (MD). In addition, we examined the effects …

The Role Of Relational And Item Specific Processing In The Survival Advantage Across English And Spanish, Crystal J. Robinson

Legacy Theses & Dissertations (2009 - 2024)

The current paper examines the effects of survival processing relative to item specific and relational processing on recall for both English monolinguals and Spanish-English bilinguals. It has been suggested that both item specific and relational processing play an important role in the survival advantage (Burns, Hart, Griffith, & Burns, 2012; Burns, Hwang, & Burns, 2011). However, to date, the generalizability of this advantage has yet to be examined cross-linguistically. In two studies, participants were asked to make survival relevance ratings, pleasantness ratings, and to categorize a set of words from either common taxonomic or ad hoc categories. Spanish-English bilinguals performed …

What You See Is What You Forget : Alcohol Cue Exposure, Affect, And The Misinformation Effect, Camille Crocken Barnes

Legacy Theses & Dissertations (2009 - 2024)

Previous research has suggested that both alcohol cues and positive affect increase the tendency to incorporate false information into memory. This series of studies sought to determine if affect mediates the influence of alcohol cues on incorporation of false information into memory. Initially, a pilot study was completed to determine the individual differences that predict which individuals experience a heightening of positive affect following visualization exercises involving alcoholic beverages. Next, a study was conducted to determine if this affect increase from exposure to alcohol cues leads to increased acceptance of misinformation into memory. Participants' memories were tested while they were …
