The Association Of Working Memory And Anxiety With Skill Acquisition And Transfer In Young And Older Adults, Isabelle Valk Jan 2004

The Association Of Working Memory And Anxiety With Skill Acquisition And Transfer In Young And Older Adults, Isabelle Valk

Theses: Doctorates and Masters

Two studies, involving a total of 184 adults between 17 and 89 years of age, were conducted to determine whether age differences in skill acquisition and transfer could be related to age differences in working memory functioning and anxiety. In both experiments, working memory functioning was measured using the Digit Span task (Wechsler, 1997) und the Reading Span tusk (Daneman & Carpenter, 1980), while anxiety levels were measured using the State Trait Anxiety Inventory (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983). Participants were required to perform a mental arithmetic task in Experiment I, and a visual numerosity task in Experiment …

Memory Matters Ii: Predictors Of Self-Care Behaviors In Young Adults With Type 1 Diabetes, Sari A. Soutor Jan 2004

Memory Matters Ii: Predictors Of Self-Care Behaviors In Young Adults With Type 1 Diabetes, Sari A. Soutor

Theses and Dissertations

Type 1 diabetes and associated hypoglycemia can result in verbal memory difficulties, yet the role of memory in daily diabetes self-care has not been evaluated for young adults. Subtests from two well-standardized memory measures were administered to 34 young adults with type 1 diabetes, aged 18-29, in this pilot study. Self-care behaviors were assessed through 24-hour diabetes care interviews, while HbAlc indicated metabolic control. Verbal associative memory uniquely accounted for 12% of the variance in blood glucose testing frequency (p p p p = .06. Single-trial verbal memory uniquely predicted 10% of the variance in metabolic control (p p < .05. Importantly, memory was the only significant predictor in each model, which indicates memory, rather than overall cognitive capacity or financial/educational resources, relates to self-care behaviors/health status. Memory, a novel factor not previously evaluated in the quest to better understand daily disease management for young adults with diabetes, is significantly related to central self-care behaviors and metabolic control. Memory predictors likely warrant additional research and clinical attention such that eventually, intervention studies might identify strategies or compensatory aids that could improve young adults' self-care behaviors and health status through facilitating better memory functioning.

Gaze-Centered Updating Of Visual Space In Human Parietal Cortex., W Pieter Medendorp, Herbert C Goltz, Tutis Vilis, J Douglas Crawford Jul 2003

Gaze-Centered Updating Of Visual Space In Human Parietal Cortex., W Pieter Medendorp, Herbert C Goltz, Tutis Vilis, J Douglas Crawford

Brain and Mind Institute Researchers' Publications

Single-unit recordings have identified a region in the posterior parietal cortex (PPC) of the monkey that represents and updates visual space in a gaze-centered frame. Here, using event-related functional magnetic resonance imaging, we identified an analogous bilateral region in the human PPC that shows contralateral topography for memory-guided eye movements and arm movements. Furthermore, when eye movements reversed the remembered horizontal target location relative to the gaze fixation point, this PPC region exchanged activity across the two cortical lobules. This shows that the human PPC dynamically updates the spatial goals for action in a gaze-centered frame.

The Lateral Occipital Complex Subserves The Perceptual Persistence Of Motion-Defined Groupings., Susanne Ferber, G Keith Humphrey, Tutis Vilis Jul 2003

The Lateral Occipital Complex Subserves The Perceptual Persistence Of Motion-Defined Groupings., Susanne Ferber, G Keith Humphrey, Tutis Vilis

Brain and Mind Institute Researchers' Publications

How are the bits and pieces of retinal information assembled and integrated to form the coherent objects that we see? One long-established principle is that elements that move as a group are linked together. For instance a fragmented line-drawing of an object, placed on a background of randomly distributed short lines, can be impossible to see. But if the object moves relative to the background, its shape is instantly recognized. Even after the motion stops, the percept of the object persists briefly before it fades into the background of random lines. Where in the brain does the percept of the …

Strategy Uses And Study Time: Relationship With Memory Performance In Older Adults, Karen A. S. Doolittle Apr 2003

Strategy Uses And Study Time: Relationship With Memory Performance In Older Adults, Karen A. S. Doolittle

Master's Theses - Daytona Beach

The overall purpose of this study was to foster a greater understanding of age-related memory loss as it pertains to the aging workforce's ability to remain productive and effective in a time of complex change, and to recommend some adjustments that can be made to compensate for these memory declines. The specific intent of this current project was to test one premise of Ericsson and Chase's Skilled Memory Theory, namely that memory skill is a skill that can be developed through enhanced encoding and through practice. By introducing participants to the simple mnemonic strategy of chunking and by allowing two …

The Influence Of Warning Label Presentation In Memory Recognition Of Aging Adults, Brian J. Call Oct 2002

The Influence Of Warning Label Presentation In Memory Recognition Of Aging Adults, Brian J. Call

Master's Theses - Daytona Beach

Research indicates that hundreds of thousands of people are injured each year as a result of poor communication between medical personnel, warning label information, and consumers when taking over the counter or prescription medication. Typically, as adults age, they are increasingly responsible for remembering the hazards of taking medications. If inadequate information exists in memory in regards to side effects, dosage, and other warnings, the likelihood of improper usage will increase. Because aging adults typically have a reduction in cognitive resources, it was hypothesized that older adults would require the aid of additional warning information to assist in the retrieval …

Emotional Episodes Facilitate Word Recall, Paula T. Hertel, C. Parks Sep 2002

Emotional Episodes Facilitate Word Recall, Paula T. Hertel, C. Parks

Psychology Faculty Research

Dysphoric and nondysphoric college students described self-generated images of themselves interacting with the referents of neutral nouns; the nouns were paired with adjectives that changed their emotional meaning (e.g., cruise ship, cargo ship, sinking ship). On the subsequent unexpected test, the nouns from emotional pairings were more frequently recalled than were those from neutral pairings, regardless of their valence or congruence with the students' mood. An examination of the initial descriptions revealed that emotional images were more distinctive, but not in a pattern correlated with recall of the corresponding nouns.

Working Memory In Schizophrenics And Older Adults : A Mediator For Episodic Memory Deficits?, Matthew W. Webster Jan 2002

Working Memory In Schizophrenics And Older Adults : A Mediator For Episodic Memory Deficits?, Matthew W. Webster

Master's Theses

The purpose of this study was to determine the role of working memory on episodic memory in older adults and adults with schizophrenia. This study included 15 adults with schizophrenia, 20 young adults without psychopathology, and 21 older adults without psychopathology. Storage working memory scores were greater than processing working memory scores in all groups. Young adults had the fewest problems with episodic and working memory, compared to older adults and adults with schizophrenia, who had similar deficits in both memory types. Speed of processing was found to be the greatest predictor of working memory capacity.

Relationship Between Neuropsychological Deficits And Cerebral Perfusion Abnormalities In Cocaine Abusers, Karen A. Tucker Jan 2002

Relationship Between Neuropsychological Deficits And Cerebral Perfusion Abnormalities In Cocaine Abusers, Karen A. Tucker

LSU Doctoral Dissertations

The purpose of this study was to investigate the relationships between the severity of cocaine/alcohol use, neuropsychological functioning, and cerebral blood flow abnormalities. Cocaine users (n = 60) and control subjects (n = 13) were administered a battery of neuropsychological tests that yielded the following factors: Attention/Executive Functioning, Memory, Simple Motor, and Sensorimotor. Participants were assessed for decreased cerebral blood flow with single-photon emission computed tomography (SPECT). Examination of group differences indicated that cocaine users performed significantly worse than controls on the Memory and Sensorimotor factors. The frequency/duration of cocaine use, alcohol use, and a combination of both substances were …

Eye Position Signal Modulates A Human Parietal Pointing Region During Memory-Guided Movements., J F Desouza, S P Dukelow, J S Gati, R S Menon, R A Andersen, T Vilis Aug 2000

Eye Position Signal Modulates A Human Parietal Pointing Region During Memory-Guided Movements., J F Desouza, S P Dukelow, J S Gati, R S Menon, R A Andersen, T Vilis

Brain and Mind Institute Researchers' Publications

Using functional magnetic resonance imaging, we examined the signal in parietal regions that were selectively activated during delayed pointing to flashed visual targets and determined whether this signal was dependent on the fixation position of the eyes. Delayed pointing activated a bilateral parietal area in the intraparietal sulcus (rIPS), rostral/anterior to areas activated by saccades. During right-hand pointing to centrally located targets, the left rIPS region showed a significant increase in activation when the eye position was rightward compared with leftward. As expected, activation in motor cortex showed no modulation when only eye position changed. During pointing to retinotopically identical …

Attention, Memory, And Self-Efficacy Differences Between Adhd And Aging Individuals, Douglas Lee Welsh Jan 2000

Attention, Memory, And Self-Efficacy Differences Between Adhd And Aging Individuals, Douglas Lee Welsh

Master's Theses

Attention and memory abilities decline with age. Although a similar pattern of attentional and memory decrement has been observed in individuals with Attention Deficit Hyperactivity Disorder (ADHD), these two populations have never been directly compared. The present study examined performance on attention, self-efficacy (SE), and memory tasks by ADHD young adults and non-ADHD younger and older adults. ADHD adults displayed lower attentional SE than both non-ADHD younger and older adults, but performed comparably to older adults on an attention task on which non-ADHD younger adults outperformed both groups. ADHD adults and older adults had lower memory SE than non-AD HD …

Capacity And Procedural Accounts Of Impaired Memory In Depression, Paula T. Hertel, T. Meiser Jan 2000

Capacity And Procedural Accounts Of Impaired Memory In Depression, Paula T. Hertel, T. Meiser

Psychology Faculty Research

Findings of impaired memory in states of dysphoria or depression are summarized and subsumed under different accounts of mood-related memory deficits. Theoretical accounts based on the assumption of a storage system of limited capacity are compared to accounts which emphasize the role of procedures and strategies in attending and remembering. Two reanalyses of a recent experiment in the process-dissociation paradigm are reported. They address issues of dysphoria-related differences in automatic versus controlled uses of memory in a task of word-stem completion. The two reanalyses rest on different assumptions about the relation between automatic and controlled components, but they converge in …

The Cognitive-Initiative Account Of Depression-Related Impairments In Memory, Paula T. Hertel Jan 2000

The Cognitive-Initiative Account Of Depression-Related Impairments In Memory, Paula T. Hertel

Psychology Faculty Research

The many and diverse interpretations of the word control make it clear that control constitutes a fundamental concern in most areas of psychology. In an illustration of this diversity, I described my interest in controlled uses of memory at a social gathering; my new acquaintances, without realizing the non sequitur, subsequently raised issues about self control and loss of control-issues much more relevant to their own interests in psychological phenomena than are my narrow musings. Yet a second thought devoted to the semantics of control reveals underlying commonalities. For example, when older people begin to have problems with controlled …

Developmental Changes In Verbal And Imaginal Mnemonic Techniques For Serial Recall, Michelle L. Rupiper Aug 1999

Developmental Changes In Verbal And Imaginal Mnemonic Techniques For Serial Recall, Michelle L. Rupiper

Student Work

Children’s ability to use mnemonic techniques was investigated in first, fourth and sixth graders. Children in each age group were assigned to one of three conditions: method of loci, story mnemonic or elaborative control group. Subjects were given three recall tests. Each test was scored with and without regard to the order in which subjects recalled the words presented. Relative to the control group, both mnemonic conditions showed an advantage in memorizing lists of 20 words. However, all conditions, including the elaborative control group showed significant increases in the number of words recalled between the baseline test and recall Test …

Traning Strategy Use And Its Effects On Working Memory Capacity, Jennifer Lynn Scott Jul 1999

Traning Strategy Use And Its Effects On Working Memory Capacity, Jennifer Lynn Scott

Psychology Theses & Dissertations

Two experiments were conducted to examine whether strategy use affects the storage component of a working memory task. In Experiment 1, all 21 participants were given training to create stories from lists of to-be-remembered words (i.e., chaining) within a short-term memory task (i.e., including only a storage task). Short-term memory task performance and working memory span task performance were examined before and after training. Both short-term memory and working memory task performance improved from pretest to post-test. In Experiment 2, the same strategy training was given to 30 participants. In addition, another 30 participants were assigned to a control condition. …

Functionally Dissociating Aspects Of Event Memory: The Effects Of Combined Perirhinal And Postrhinal Cortex Lesions On Object And Place Memory In The Rat., T J Bussey, J L Muir, J P Aggleton Jan 1999

Functionally Dissociating Aspects Of Event Memory: The Effects Of Combined Perirhinal And Postrhinal Cortex Lesions On Object And Place Memory In The Rat., T J Bussey, J L Muir, J P Aggleton

Brain and Mind Institute Researchers' Publications

Reciprocal interactions between the hippocampus and the perirhinal and parahippocampal cortices form core components of a proposed temporal lobe memory system. For this reason, the involvement of the hippocampus in event memory is thought to depend on its connections with these cortical areas. Contrary to these predictions, we found that NMDA-induced lesions of the putative rat homologs of these cortical areas (perirhinal plus postrhinal cortices) did not impair performance on two allocentric spatial tasks highly sensitive to hippocampal dysfunction. Remarkably, for one of the tasks there was evidence of a facilitation of performance. The same cortical lesions did, however, disrupt …

Memory Self-Efficacy In Its Social Cognitive Context, Jane M. Berry Jan 1999

Memory Self-Efficacy In Its Social Cognitive Context, Jane M. Berry

Psychology Faculty Publications

This chapter takes a primarily cognitive construct - memory self-efficacy (MSE) - and returns it to its roots - social cognition (Bandura, 1986). This is a natural and obvious move. MSE has evolved since the mid-1980s (Berry, West, & Powlishta, 1986; Hertzog, Dixon, Schulenberg, & Hultsch, 1987) to its present identity and status in the cognitive aging and adult developmental research literature. If it is to avoid becoming a hypothesis in search of data (Light, 1991) or worse, an epiphenomenon to more robust explanations of cognitive aging (e.g., speed) (Salthouse, 1993), its potential and limits must be scrutinized and subjected …

Depression-Related Impairments In Prospective Memory, S. S. Rude, Paula T. Hertel, W. Jarrold, J. Covich, S. Hedlund Jan 1999

Depression-Related Impairments In Prospective Memory, S. S. Rude, Paula T. Hertel, W. Jarrold, J. Covich, S. Hedlund

Psychology Faculty Research

Time-based prospective memory, the ability to carry out a future intention at a specified time, was found to be impaired in a community sample of clinically depressed adults, relative to a nondepressed sample. Nondepressed participants monitored the time more frequently and, in the final block of the task, accelerated time-monitoring as the target time for the prospective memory response approached. These results are consistent with previous findings of depression-related impairments in retrospective memory tasks that require controlled, self-initiated processing.

Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling Jan 1998

Perception Of Mode, Rhythm, And Contour In Unfamiliar Melodies: Effects Of Age And Experience, Andrea R. Halpern, James C. Bartlett, W. Jay Dowling

Faculty Journal Articles

We explored the ability of older (60-80 years old) and younger (18-23 years old) musicians and nonmusicians to judge the similarity of transposed melodies varying on rhythm, mode, and/or contour (Experiment 1) and to discriminate among melodies differing only in rhythm, mode, or contour (Experiment 2). Similarity ratings did not vary greatly among groups, with tunes differing only by mode being rated as most similar. In the same/different discrimination task, musicians performed better than nonmusicians, but we found no age differences. We also found that discrimination of major from minor tunes was difficult for everyone, even for musicians. Mode is …

Relation Between Rumination And Impaired Memory In Dysphoric Moods, Paula T. Hertel Jan 1998

Relation Between Rumination And Impaired Memory In Dysphoric Moods, Paula T. Hertel

Psychology Faculty Research

College students in dysphoric or nondysphoric moods studied pairs of words and later took a fragment-completion test of memory for targets from the pairs (under process-dissociation procedures for obtaining estimates of controlled and automatic retrieval; L. L. Jacoby, 1996). Between the study and test phases, some participants waited quietly for 7 min; others rated self-focused materials designed to invoke ruminations in the dysphoric group; and still others rated self-irrelevant and task-irrelevant materials. A dysphoria-related impairment in controlled retrieval occurred in the first 2 conditions but not in the 3rd condition. These results show that the nature of task-irrelevant thoughts contributes …

Right Medial Temporal-Lobe Contribution To Object-Location Memory, B Milner, Ingrid Johnsrude, J Crane Oct 1997

Right Medial Temporal-Lobe Contribution To Object-Location Memory, B Milner, Ingrid Johnsrude, J Crane

Brain and Mind Institute Researchers' Publications

An important aspect of normal human memory, and one humans share with many other species, is the ability to remember the location of objects in their environment. There is by now strong evidence from the study of epileptic patients undergoing brain surgery that right temporal-lobe lesions that encroach extensively upon the hippocampal and parahippocampal gyrus impair the delayed, but not the immediate, recall of the location of objects within a random array. These findings have now been extended to a multiple-trial, spatial-array learning task; by including not only patients tested after unilateral anterior temporal lobectomy but also those with a …

Repressed Memories Of Repeated Sexual Abuse: From Real Incest To The Emergence Of False Memories, Alice M. Donovan

Master of Liberal Studies Theses

Incest and childhood sexual abuse have been and continue to be a problem in our society. However, Today a relatively new phenomena involving repressed memories of childhood sexual abuse plagues our society. Women, and some men, between the ages of 25 to 40 who have sought therapy for relatively common problems such as marital difficulties, work related problems, eating disorders or simple depression: without ever having any memories of being sexually abused as a child, have come to believe while in therapy that they were the victims of repeated childhood sexual abuse. Thousands of people are remembering such abuse, and …

The Use Of Prior Knowledge In Learning From Examples, Stephen B. Blessing '89

Doctoral Dissertations

This dissertation examines the way people acquire procedures from examples, and provides a computational model of the results. In four experiments, people learned an analog of algebra. For each experiment, the initial know ledge that people had of the task was varied. In two experiments (Experiments 1 and 3), the syntactic know ledge that people had concerning the task w as manipulated. The knowledge of syntax that participants had, particularly the ability to correctly parse the character string, was found to be a major determiner in the way participants acquired the rules. Experiment 2 explicitly manipulated participant's awareness as to …
