Affect Identification And Interpersonal Skills: An In-Depth Evaluation Of Social Cognition In Schizophrenia, Griffin Pollock Sutton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The presence of deficits in various sub-domains of social cognition has been investigated to a degree in individuals with schizophrenia. Some of the most commonly researched and documented deficits have included impairments in the identification of affect portrayed in faces. Research has indicated that the performance of individuals with schizophrenia on such tasks is generally impaired as compared to normal controls. However, some have questioned the generalizability of such findings to real-world situations, as day-to-day interactions generally necessitate a constant, fluid assessment of the thoughts and feelings of others and are rarely, if ever, limited to still images of others. …

Effects Of Method And Context Of Note-Taking On Memory: Handwriting Versus Typing In Lecture And Textbook-Reading Contexts, Ian Schoen

Pitzer Senior Theses

Both electronic note-taking (typing) and traditional note-taking (handwriting) are being utilized by college students to retain information. The effects of the method of note-taking and note-taking context were examined to determine if handwriting or typing notes and whether a lecture context or a textbook-reading context influenced retention. Pitzer College and Scripps College students were assigned to either handwrite or type notes on a piece of academic material presented in either a lecture or textbook context and were given a test to assess their retention. The results demonstrated that there was a significant main effect for typing notes such that typing …

Linguistic Devices, Emotionality, And Memorability Of Computer Mediated Communication, Angela M. Mion

Undergraduate Honors Thesis Collection

I examined whether college students use shortcuts, pragmatics, and errors in text messages differently depending on their gender and the emotionality of the message. Results indicate that the prevalence of particular shortcuts differed across happy, sad, and angry messages, but gender did not influence use of linguistic devices. In a second study, I examined the emotionality and memorability of text messages versus voicemails. Results indicate that texts may be remembered better than voicemails, and happy, sad, and angry messages may be remembered differently by men and women.

Hippocampal Theta And Gamma: Effects Of Aging, Environmental Change, Cholinergic Activation And Learning, Matthew D. Howe

Honors Scholar Theses

During aging, hippocampal functioning is impaired; specifically aged humans and rats show reduced performance on spatial memory tasks. An age-related reduction in the neurotransmitter acetylcholine has been postulated to underlie this impairment. Rhythmic oscillations (theta, gamma) may serve to synchronize activity within the hippocampus and across the brain during learning; these may also change with aging.

To determine what aspects of oscillation are important for memory processing, the effects of aging, encountering a novel situation, learning a new task and cholinergic system activation (with physostigmine) were examined. Both age groups showed increased theta, but not gamma activity when encoding a …

The Possible Effects Silence And Music Listening Have On Memory, Allisha Rounds

Undergraduate Psychology Research Methods Journal

College students often can be seen listening to music while studying in the library and around campus. Previous research indicates that some instrumental music can be beneficial to a person’s ability to recall information such as words, while lyrical music can have the opposite effect. Further studies have shown students do poorly on reading comprehension tests when listening to popular music than if they were sitting in silence. The current research aimed to look at music listening compared to memorization abilities. Thirty participants from the Lindenwood Participant Pool were asked to memorize two short passages. One passage was given in …

Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson

Graduate Theses and Dissertations

When an eyewitness suffers an impairment of memory for a criminal's face because the criminal used a weapon during the commission of the crime, this impairment is called the weapon focus effect. Literature provides two explanations for how this effect arises: some implicate the narrowing of attentional cues to the weapon during the commission of a crime because arousal of the victim increases, while others claim that the weapon is merely a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm taking place in a …

Interactive Effects Of Working Memory Self-Regulatory Ability And Relevance Instructions On Text Processing, Nancy Jo Hamilton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reading is a process that requires the enactment of many cognitive processes. Each of these processes uses a certain amount of working memory resources, which are severely constrained by biology. More efficiency in the function of working memory may mediate the biological limits of same. Reading relevancy instructions may be one such method to assist readers in utilizing working memory resources more efficiently.

This study examines the relationship between perspective relevance instructions and participants' ability to regulate their working memory resources. In a 3 x 2 x 2 design the study extended the literature by utilizing a measure of fluid …

Time-Of-Day Effects On Younger And Older Adult Executive Functioning, Carly E. Violand

ETD Archive

The most recent time-of-day (TOD) body of research has explored how TOD effects can influence certain cognitive domains such as semantic memory, episodic memory, processing speed, and executive functioning (Allen et al., 2008). Research by Horne and Ostberg (1976) has shown how differences in age can be associated with a preference for a certain TOD (i.e., morning or afternoon). Seventy-five percent of adults 65 years or older tend to prefer the morning, whereas fewer than 10 of younger adults tend to prefer the afternoon (Horne & Ostberg, 1976 West et al., 2002). Research by Allen and colleagues (2008) has shown …

The Impact Of Sleep Quality On Cognitive Functioning In Parkinson's Disease, Karina Stavitsky, Sandra Neargarder, Yelena Bogdanova, Patrick Mcnamara, Alice Cronin-Golomb

Psychology Faculty Publications

In healthy individuals and those with insomnia, poor sleep quality is associated with decrements in performance on tests of cognition, especially executive function. Sleep disturbances and cognitive deficits are both prevalent in Parkinson's disease (PD). Sleep problems occur in over 75% of patients, with sleep fragmentation and decreased sleep efficiency being the most common sleep complaints, but their relation to cognition is unknown. We examined the association between sleep quality and cognition in PD. In 35 non-demented individuals with PD and 18 normal control adults (NC), sleep was measured using 24-hr wrist actigraphy over 7 days. Cognitive domains tested included …

Melatonin And Its Effect On Learning And Memory, Nechama Leah Bauman (Cahn)

The Science Journal of the Lander College of Arts and Sciences

Melatonin is a neurohormone produced by the pineal gland and secreted into the body in a circadian rhythm. Melatonin is known to be involved in many vital body functions, including sleep, reproduction, and immune response. Exogenous melatonin, sold as over the counter natural supplements in drugstores, is commonly taken by many people to help cure various ailments. Melatonin also plays a role in the hippocampus. This paper investigates the effects of melatonin on long-term potentiation in the hippocampus. Long-term potentiation, described as a long-lasting strengthening of synapses between nerve cells, is thought to be responsible for long-term memory retention. It …

Responses To Domestic Violence Public Service Ads: Memory, Attitudes, Affect, And Individual Differences, Courtney Elizabeth Welton-Mitchell

Electronic Theses and Dissertations

Public service ads (PSAs) are an increasingly visible part of efforts to decrease the occurrence and consequences of domestic violence. Like other advertising, domestic violence PSAs are designed to grab attention, influence attitudes, and enhance memory for ad content. Over the years, images in domestic violence PSAs have changed substantially; agencies have started using pictures that generate emotions - either vivid negative images (bruised faces or body parts), or positive images (smiling faces) that contrast with the negative text. It is not clear, however, how different types of ad images influence memory for the message and attitudes about domestic violence, …

Dynamic Aspects Of Musical Imagery, Andrea R. Halpern

Faculty Conference Papers and Presentations

Auditory imagery can represent many aspects of music, such as the starting pitches of a tune or the instrument that typically plays it. In this paper, I concentrate on more dynamic, or time-sensitive aspects of musical imagery, as demonstrated in two recently published studies. The first was a behavioral study that examined the ability to make emotional judgments about both heard and imagined music in real time. The second was a neuroimaging study on the neural correlates of anticipating an upcoming tune, after hearing a cue tune. That study found activation of several sequence-learning brain areas, some of which varied …

The Reversed Testing Effect : Unraveling The Benefits Of Practiced Recall, Katherine Mary Weber

Legacy Theses & Dissertations (2009 - 2024)

Eyewitness memory for events has been shown to be malleable and susceptible to intrusions of misinformation (Loftus & Palmer, 1974). It has been demonstrated that practicing retrieval of studied material can lead to improved recall, known as the testing effect (Karpicke & Roediger, 2008; Roediger & Karpicke, 2006). However, practiced recall may also lead to the increased incorporation of misinformation into memory, known as the reversed testing effect (Chan, Thomas, & Bulevich, 2009). While Karpicke and Roediger (2008) used Swahili-English word pairs to demonstrate the testing effect, Chan et al. used video materials. In two out of three of the …

True Chance On The Test Of Memory Malingering (Tomm) : A Descriptive And Inferential Item Analysis, Andrea Miele

Legacy Theses & Dissertations (2009 - 2024)

The Test of Memory Malingering (TOMM) was once purported to be among the "most frequently administered" neuropsychological tests of performance validity (Slick, Tan, Strauss & Hultsch, 2004). Much research involving clinical patients as well as individuals involved in medico-legal cases, however, has revealed that the TOMM may not perform as well as initially conceived during the test's early validation studies. For this reason, other performance validity tests have likely surpassed the TOMM; however, work is currently underway to increase the test's sensitivity to performance invalidity, usually through differential cutoff selection. The purpose of this study was to collect data on …

Trauma Severity And Defensive Emotion-Regulation Reactions As Predictors Of Forgetting Childhood Trauma, Bette L. Bottoms, Cynthia J. Najdowski, Michelle A. Epstein, Matthew J. Badanek

Psychology Faculty Scholarship

Using a retrospective survey, we studied a sample of 1679 college women to determine whether reports of prior forgetting of sexual abuse, physical abuse, and other traumas could be explained by trauma severity and individual differences in the use of defensive emotion-regulation reactions (i.e., repressive coping, dissociation, and fantasy proneness). Among victims of physical abuse (but not sexual abuse or other types of trauma), those who experienced severe abuse and used defensive reactions were sometimes more likely to report temporary forgetting of abuse, but other times less likely to report forgetting. We also found unanticipated main effects of trauma severity …

Epigenetics: A Possible Mechanism Of Memory, Aliza Grossman Rubenstein

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction to this article: The mind-body connection has fascinated philosophers and scientists for centuries. How is it possible that consciousness arises from a lump of matter known as the brain? How does neurons’ firing affect choice and beliefs? How do the electrochemical properties of the brain allow for the memory of events long after they’ve occurred? One of the most studied of these areas is that of memory. Researchers seek to understand the biological basis behind memory and how that biology is affected in individuals suffering from memory disorders.

Implicit And Explicit Memory Performance In Bilinguals: Implications For Transfer-Appropriate Processing And Vocabulary Learning, Elva Natalia Strobach

Open Access Theses & Dissertations

Two experiments examined whether translation and sentence context improved memory performance in explicit and implicit memory. For explicit memory, an effect of translation was found such that translation led to better item recognition than read aloud encoding. Sentence context did not benefit recognition memory performance. For implicit memory, neither translation nor sentence context led to priming in a word-stem completion paradigm. The results are discussed in terms of the transfer-appropriate processing framework.

The Truth About Lying: The Memorial Effects Of Deliberately Producing Misinformation, Kathleen M. Vieira

LSU Master's Theses

There are different ways of lying and these lies may have different impacts on memory. In this study, participants studied pictures of objects, and later lied and told the truth about these and other objects by describing them or by denying they had seen them. Forty-eight hours later, participants were tested on their source memory. Results revealed that participants had good memory for having falsely described a never-seen object, but poor memory for having falsely denied seeing a studied object. These results suggest that telling certain types of lies may make a person more likely to forget having lied at …

Visual Memory Improvement In Recognition, Allison Prandl

Theses : Honours

Fluid intelligence and working memory has been improved by training on a visual working memory n-back task (Jaeggi, Buschkuehl, Jonides & Perrig, 2008). The present study investigated whether n-back training can improve visual memory using a test of visual recognition. A sample of 47 participants were trained for 20 days on either the single n-back task (n = 26) or a general knowledge and vocabulary task (n = 21). The results showed that training using the single n-back task did not significantly increase scores on a test of visual recognition when compared with general knowledge and vocabulary training. However, when …

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …

The Role Of Emotional Expression On Person Identity Recognition, Kristen Paris

Electronic Theses and Dissertations

Facial information concerning person identity and emotional expression is vital to human social interaction, and therefore, we find it beneficial to remember the faces we see. Little is known, however, about whether emotional expressions facilitate or inhibit recognition for person identity. The present studies examined the role of emotional expression on person identity recognition by manipulating whether such information was presented at encoding (i.e., initial perception of the actor) or at recognition (i.e., later memory for the actor). In Experiment 1, participants recognized more actors displaying an angry rather than a happy expression, when they initially saw actors display a …

Semantic Priming Of Familiar Songs, Sarah K. Johnson, Andrea R. Halpern

Faculty Journal Articles

We explored the functional organization of semantic memory for music by comparing priming across familiar songs both within modalities (Experiment 1, tune to tune; Experiment 3, category label to lyrics) and across modalities (Experiment 2, category label to tune; Experiment 4, tune to lyrics). Participants judged whether or not the target tune or lyrics were real (akin to lexical decision tasks). We found significant priming, analogous to linguistic associative-priming effects, in reaction times for related primes as compared to unrelated primes, but primarily for within-modality comparisons. Reaction times to tunes (e.g., "Silent Night") were faster following related tunes ("Deck the …

Age And Premorbid Intelligence Suppress Complaint-Performance Congruency In Raw Score Measures Of Memory, Matthew Merema, Craig Speelman, Elizabeth Kaczmarek, Jonathan Foster

Research outputs 2012

Background: We aimed to examine the role of age and premorbid intelligence (IQ) in suppressing the relationship between subjective memory complaints (SMCs) and raw score memory performance. Methods: We used a community sample of older adults aged 66"90 years (N = 121) to test whether the inclusion of age and a premorbid IQ measure in multiple regression analyses increased semipartial correlations of raw score memory performance in predicting SMCs. Rank contrast correlations were also carried out to observe how age and premorbid IQ are related to complaint"performance congruency. Measures utilized in the study included the Memory Functioning Questionnaire (for SMCs), …

Age Differences In Revision Of Causal Belief, Kristi M. Simmons

Masters Theses & Specialist Projects

Inductive reasoning (IR) requires efficient working memory (WM). Research shows that the prefrontal cortex (PFC) is involved during WM tasks and that PFC functioning declines with age. The ability to comprehend and update text-based information requires an intact PFC and efficient WM and IR. The current study presented a series of messages about the investigation of a warehouse fire to 48 young and 48 older adults. One message contained a piece of misinformation which another message corrected later. It was hypothesized that a memory cue to the misinformation with the correction statement should benefit older adults the most during the …

Event Perception, Gabriel A. Radvansky, Jeffrey M. Zacks

Psychological & Brain Sciences Faculty Research

Events are central elements of human experience. Formally, they can be individuated in terms of the entities that compose them, the features of those entities, and the relations amongst entities. Psychologically, representations of events capture their spatiotemporal location, the people and objects involved, and the relations between these elements. Here, we present an account of the nature of psychological representations of events and how they are constructed and updated. Event representations are like images in that they are isomorphic to the situations they represent. However, they are like models or language in that they are constructed of components rather than …

Recollection Is Impaired By The Modification Of Interpretation Bias, Paula T. Hertel, Elaina Vasquez, Amanda Benbow, Megan Hughes

Psychology Faculty Research

The interpretation paradigm of cognitive-bias modification (CBM-I) was modified with instructions used in process-dissociation procedures for the purpose of investigating processes contributing to performance on the transfer task. In Experiment 1 nonanxious students were trained to interpret ambiguous situations in either a negative or benign way (or they read nonambiguous scenarios). They were then asked to respond to new ambiguous situations in the same way as contextually similar analogues during training, or to respond differently. Benign training proactively impaired memory for negative outcomes. This effect was replicated by anxious students in Experiment 2 and discussed with respect to the assumptions …

Cognitive Bias Modification: Past Perspectives, Current Findings, And Future Applications, Paula T. Hertel, A. Mathews

Psychology Faculty Research

Research conducted within the general paradigm of Cognitive Bias Modification (CBM) reveals that emotional biases in attention, interpretation, and memory are not merely associated with emotional disorders but contribute to them. After briefly describing research on both emotional biases and their modification, we examine similarities between CBM paradigms and older experimental paradigms used in research on learning and memory. We also compare the techniques and goals of CBM research to other approaches to understanding cognition/emotion interactions. From a functional perspective, the CBM tradition reminds us to use experimental tools to evaluate assumptions about clinical phenomena and more generally, about causal …

Does Crowding Obscure The Presence Of Attentional Guidance In Contextual Cueing?, Steven William Fiske

USF Tampa Graduate Theses and Dissertations

The contextual cueing effect was initially thought to be the product of memory guiding attention to the target location. However, the steep search slopes obtained in contextual cueing indicate an absence of attentional guidance. We hypothesized that crowding could be obscuring the presence of attentional guidance and investigated this possibility in 2 experiments. Crowding was manipulated by varying the density of items in the local target region in a contextual cueing task. We observed a significant reduction in search slopes between the novel and repeated conditions when crowding was reduced. Enhancing crowding eliminated the contextual cueing effect. These findings suggest …

The Neural Correlates Of Retrospective Memory Monitoring: Convergent Findings From Erp And Fmri, Jeremy Clark Roper

Theses and Dissertations

Monitoring the accuracy of memory is an automatic but essential process of memory encoding and retrieval. Retrospective memory confidence judgments are making effective and efficient decisions based on one's memories. The neural processes involved in retrospective confidence ratings were investigated with EEG and fMRI using a recognition memory task designed such that participants also rated their confidence in their memory response. Correct trials (hits and correct rejections) were examined for differences related to the participants' level of confidence in their response. There were significant differences in electrophysiological activity (in the FN400 and the late parietal component) associated with confidence rating, …
