The Enhancing Effect Of Retrieval On Subsequent Encoding: Understanding Test-Potentiated Learning, Kathleen Marie Arnold

Arts & Sciences Graduate Student Theses and Dissertations

Retrieval practice directly enhances later memory of tested material, a robust effect known as the testing effect (Roediger & Karpicke, 2006b). Numerous experiments have provided support for this effect. However, another important effect of retrieval practice has received far less attention. Retrieval practice can also indirectly enhance learning by potentiating subsequent encoding of tested material, an effect known as test-potentiated learning (Izawa, 1966). Although introduced over four decades ago, little is known about how and when tests enhance subsequent encoding, information that has both practical and theoretical importance. The aim of this dissertation was to enhance understanding of test-potentiated learning …

Goal Commitments And The Content Of Thoughts And Dreams: Basic Principles, Eric Klinger

Psychology Publications

A few empirically supported principles can account for much of the thematic content of waking thought, including rumination, and dreams. (1) An individual’s commitments to particular goals sensitize the individual to respond to cues associated with those goals. The cues may be external or internal in the person’s own mental activity. The responses may take the form of noticing the cues, storing them in memory, having thoughts or dream segments related to them, and/or taking action. Noticing may be conscious or not. Goals may be any desired endpoint of a behavioral sequence, including finding out more about something, i.e., exploring …

Dentate Gyrus Volume And Memory Strength In Older Adults, J. Andrew Hartshorn, Dr. Brock Kirwan

Journal of Undergraduate Research

I began work in the BYU Memory and Cognition Lab in the fall of 2009. Under the direction of Dr. Kirwan I was fortunate enough to be involved in a variety of projects using different testing methodologies. My first project examined the ability of people to distinguish between similar memories (pattern separation). A subsequent study utilized EEG tests to determine subjects’ abilities to rate the confidence of their memories of presented words.

To Live Is To Die: The Effect Of Mortality Salience On Memory And Fear Of Death, Tony F. Bergamini

Undergraduate Honors Thesis Collection

Terror Management Theory proposes that the threat of death produces existential terror, which accentuates the need for security. This effect of mortality salience awareness of death-is well documented for non-conscious thoughts of death (Martens, Burke, Schimel, & Faucher, 2011). The objective of this study, then, is to measure anxiety-or fear of death-in reaction to non-conscious as well as conscious thoughts of death by manipulating the valence (positive vs. negative) and content (death vs. non-death) of a story that participants read. I measured any changes reported in fear of death before and after reading the story. Participants also wrote about their …

Does The Difference Between Handwriting And Typing Influence Memory Ability?, Ai Shinohara

Undergraduate Psychology Research Methods Journal

Technology has had a great impact on education today. Computer skills are necessary in order to complete many school assignments, and typing on the computer has become a main writing method for younger generations (Burnhart & Goldinger, 2010). Many college students bring their computers in the classroom, and more and more students have started to take notes by typing on their computer instead of handwriting their notes. The question to this convenient society is whether the new writing method, typing, affects students’ memory abilities in a classroom situation. The current study was conducted to determine if handwriting or typing was …

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …

Olfactory Working Memory: The Role Of Perceived Odor Name-Ability, Spencer Lawrence Macadams

Masters Theses and Doctoral Dissertations

The purpose of this study was to examine the relationship among three factors: perceived odorant name ability, whether the odorant was ingested through a single nostril or both nostrils, and how the odorant is represented in working memory. Participants smelled odorants through the left or right nostril or with both nostrils and then provided an identifying label for each odor and rated how accurately their label represented the odor. After a short delay, the participants were given a new stimulus set consisting of new and old odorants. Participants were asked to provide a label for the odor and determine whether …

Shared Neural Substrates Of Emotionally Enhanced Perceptual And Mnemonic Vividness, Rebecca M. Todd, Taylor W. Schmitz, Josh Susskind, Adam K. Anderson

Brain and Mind Institute Researchers' Publications

It is well known that emotionally salient events are remembered more vividly than mundane ones. Our recent research has demonstrated that such memory vividness is due in part to the subjective experience of emotional events as more perceptually vivid, an effect we call emotion-enhanced vividness, or EEV. The present study built on previously reported research in which fMRI data were collected while participants rated relative levels of visual noise overlaid on emotionally salient and neutral images. Ratings of greater EEV were associated with greater activation in the amygdala, visual cortex, and posterior insula. In the present study, we measured BOLD …

The Rhetorical Canon Of Memory And The Assistive Use Of Mnemonics, Jonathan Bobby

Masters Theses

People often imagine at some point in their existence what it would be like to have a photographic memory. However, this mental aptitude is a misnomer, and extremely rare in humankind. What we possess from our Creator is a photographic mind. Our memory recall is based on the recognition of visual pictures that appear in our mind. The early communication theorists illustrated this recognition and described it in the fourth canon of rhetoric. Because of the advancements in information technology, memory no longer holds the significance it once did. Numerous academic texts refer to memory as the lost art of …

Self-Defining Memories, Scripts, And The Life Story: Narrative Identity In Personality And Psychotherapy, Jefferson A. Singer, Pavel Blagov, Meredith Berry, Kathryn M. Oost

Psychology Faculty Publications

An integrative model of narrative identity builds on a dual memory system that draws on episodic memory and a long-term self to generate autobiographical memories. Autobiographical memories related to critical goals in a lifetime period lead to life-story memories, which in turn become self-defining memories when linked to an individual's enduring concerns. Self-defining memories that share repetitive emotion-outcome sequences yield narrative scripts, abstracted templates that filter cognitive-affective processing. The life story is the individual's overarching narrative that provides unity and purpose over the life course. Healthy narrative identity combines memory specificity with adaptive meaning-making to achieve insight and well-being, as …

The Role Of World Knowledge And Episodic Memory In Scripted Narratives, Micah L. Mumper

Psychology Honors Projects

Readers recruit information from both general world knowledge and episodic memory during reading comprehension. The present experiment used eye tracking to investigate the time-course of how these two sources of memory interact. Participants read passages describing scenarios in which an actor performs a role that was either scriptually appropriate or inappropriate. Half the passages containing the inappropriate role-filler were preceded by an episodic justification for this scriptural violation. Using the same paradigm, Cook and Myers (2004) found context had an early influence on the integration of the role-filler, but world knowledge showed a later effect in the post-target region. The …

Mice With Deficient Bk Channel Function Show Impaired Prepulse Inhibition And Spatial Learning, But Normal Working And Spatial Reference Memory., Marei Typlt, Magdalena Mirkowski, Erin Azzopardi, Lukas Ruettiger, Peter Ruth, Susanne Schmid

Brain and Mind Institute Researchers' Publications

Genetic variations in the large-conductance, voltage- and calcium activated potassium channels (BK channels) have been recently implicated in mental retardation, autism and schizophrenia which all come along with severe cognitive impairments. In the present study we investigate the effects of functional BK channel deletion on cognition using a genetic mouse model with a knock-out of the gene for the pore forming α-subunit of the channel. We tested the F1 generation of a hybrid SV129/C57BL6 mouse line in which the slo1 gene was deleted in both parent strains. We first evaluated hearing and motor function to establish the suitability of this …

Differential Effects Of Parkinson's Disease And Dopamine Replacement On Memory Encoding And Retrieval., Alex A Macdonald, Ken N Seergobin, Adrian M Owen, Ruzbeh Tamjeedi, Oury Monchi, Hooman Ganjavi, Penny A Macdonald

Brain and Mind Institute Researchers' Publications

Increasingly memory deficits are recognized in Parkinson's disease (PD). In PD, the dopamine-producing cells of the substantia nigra (SN) are significantly degenerated whereas those in the ventral tegmental area (VTA) are relatively spared. Dopamine-replacement medication improves cognitive processes that implicate the SN-innervated dorsal striatum but is thought to impair those that depend upon the VTA-supplied ventral striatum, limbic and prefrontal cortices. Our aim was to examine memory encoding and retrieval in PD and how they are affected by dopamine replacement. Twenty-nine PD patients performed the Rey Auditory Verbal Learning Test (RAVLT) and a non-verbal analogue, the Aggie Figures Learning Test …

Assessment Of Verbal And Nonverbal Memory And Learning In Abstinent Alcoholics, Alyson L. Phelan

ETD Archive

Neuropsychological performance was measured in chronic alcoholics who maintained abstinence for at least six months and with matched controls. Specifically, measures of verbal memory were assessed utilizing the Rey Auditory Verbal Learning Test (RAVLT) and measures of nonverbal memory with the Rey Osterreith Complex Figure Test (ROCF) and a new measure, the Poreh Nonverbal Memory Test (PNMT). In addition, both the RAVLT and the PNMT provide a measure of operationalized learning, as they are multi-trial tasks utilizing five trials to assess recall in each trial. Verbal memory includes the ability to encode, store and retrieve information for words, language and …

Hypnosis, Hypnotizability, Memory And Involvement In Films, Reed Maxwell

Graduate Dissertations and Theses

Researchers have reported increased involvement in reading (Baum and Lynn, 1981) and music-listening (Snodgrass and Lynn, 1989) tasks during hypnosis. We predicted a similar effect for film viewing of greater absorption and involvement in an emotional (The Champ) versus a non-emotional ( Scenes of Toronto) film clip. We also examined the effects of hypnosis and film valence on memory and state depersonalization. Our study is the first to use state dissociation to index response to hypnosis. We tested 121 participants who completed measures of absorption and trait dissociation and the Harvard Group Scale of Hypnotic Susceptibility and …

Behavioral Markers Of Chronic Low-Level Lead Exposure In Young Mice, Mayra Gisel Flores Montoya

Open Access Theses & Dissertations

Behavioral markers of chronic low-level lead exposure in young mice were examined in the present study. Three groups of C57BL/6J mice (N = 35) were exposed from birth to PND 28 to one of three lead acetate levels: 0 ppm (control), 30 ppm (low-dose), or 330 ppm (high-dose). On PND 28, and immediately prior to sacrifice, mice were tested on the novel odor recognition task [(NODR) (memory task)], on the open field task [(OF) (exploratory behavior, habituation, and anxiety behavior task)], and on the nose poke task [(NP) (exploratory behavior task)]. Blood lead levels were analyzed with inductively coupled plasma …

Eyewitness Memory In Adults, Carlos Manuel Vargas

Open Access Theses & Dissertations

This study encompasses the areas of eyewitness misidentifications and eyewitness suggestibility by developing a Video Suggestibility and Eyewitness Identification Scale for adults. Two hundred one college students were recruited to test this novel psychometric scale following procedures loosely based on the Gudjonsson Suggestibility Scales. The two main subscales proposed are labeled True, which measures non-leading questions answered correctly, and Yield, which measures questions endorsed based on misinformation; two lineup identification subscales were also analyzed for exploration. Reliability estimates showed acceptable internal consistency of True and Yield subscales after negative feedback was provided; while reliability in Target Present Lineups increased and …

Changing Room Cues Reduces The Effects Of Proactive Interference In Clark’S Nutcrackers, Nucifraga Columbiana, Jody L. Lewis, Alan C. Kamil, Kate E. Webbink

Avian Cognition Papers

To determine what factors are important for minimizing interference effects in spatial memory, Clark’s Nutcrackers, Nucifraga columbiana were tested for their spatial memory for two serial lists of locations per day. In this experiment two unique landmark sets were either different between List 1 and List 2 or the same. We found that Nutcrackers were most susceptible to interference when the landmark sets were the same. This study suggests that repeatedly testing animal memory in the same room, with the same cues, can hamper recall due to interference.

Googling To Forget: The Cognitive Processing Of Internet Search, Elizabeth T. Friede

CMC Senior Theses

Technology is currently extremely integrated with everyday life. Popular media has made bold claims that the internet is making us “dumber” and people struggle to remember information more now than they ever have in the past. Scientific research on the effect of internet search on cognition and memory is still in its infancy. This research will analyze the literature and theories discussing memory and the internet. Based on an original experiment by Sparrow, Liu, and Wegner. 20 participants (10 young adults and 10 older adults) performed a typing task with twenty trivia statements, followed by a recall and recognition memory …

Semantic Memory Functional Mri And Cognitive Function After Exercise Intervention In Mild Cognitive Impairment, J Carson Smith, Kristy A. Nielson, Piero Antuono, Jeri-Annette Lyons, Ryan J. Hanson, Alissa Butts, Nathan Hantke, Matthew D. Verber

Psychology Faculty Research and Publications

Mild cognitive impairment (MCI) is associated with early memory loss, Alzheimer's disease (AD) neuropathology, inefficient or ineffective neural processing, and increased risk for AD. Unfortunately, treatments aimed at improving clinical symptoms or markers of brain function generally have been of limited value. Physical exercise is often recommended for people diagnosed with MCI, primarily because of its widely reported cognitive benefits in healthy older adults. However, it is unknown if exercise actually benefits brain function during memory retrieval in MCI. Here, we examined the effects of exercise training on semantic memory activation during functional magnetic resonance imaging (fMRI). Seventeen MCI participants …

Examining Effects Of Picture Content On False Recognition In Consistent And Inconsistent Handers., Rosanna G. Scott

College of Arts & Sciences Senior Theses

Multiple previous studies agree that inconsistent handers exhibit a memory advantage over consistent handers, oftentimes in reference to inconsistents exhibiting lower false alarm rates. Two recent studies have found contrasting data, demonstrating that, compared to consistently handed individuals, inconsistently handed individuals exhibit a higher false alarm rate in recognition memory following the encoding of pictures of objects, regardless of whether lures are pictures or object names. From this research, it is unclear whether inconsistent individuals have difficulty remembering pictures of all types, or only pictures of objects. In the current study, participants studied pictures without focal objects (i.e., landscapes and …

Separating Component Signals Of Episodic Simulation Using A Catch Trial Design, Adrian W. Gilmore

All Theses and Dissertations (ETDs)

Tasks that require mentally simulating events, such as remembering events from one’s past and imagining events from one’s future, have been shown to involve a highly overlapping set of brain regions. Across a growing number of studies, relatively few regions have been found that show differences in activity between remembered and imagined events. However, studies have not disambiguated neural activity related to task orientation: i.e., preparing to remember events from the past or imagine events in the future) from activity related simulating events, per se. The current experiment uses functional MRI and employs a catch trial design to test the …

Does Inconsistent-Handedness Lead To A Better Memory Or Does A Better Memory Lead To Inconsistent-Handedness?, Emily K. Carris

College of Arts & Sciences Senior Theses

The purpose of the study is measure the effect of handedness and hand use on memory for how specific tasks were performed. The hypothesis of the present study is that inconsistent-handers will have better memory than consistent-handers for the hand or hands they used to perform tasks. Data analysis was preformed on 30 inconsistent-handers and 45 consistent-handers, as classified by the modified Edinburg Handedness Inventory. Tasks were performed in five different hand-use conditions: always left, usually left, no preference, usually right, and always right. The results were that both consistency of handedness and hand use had an effect on memory. …

Brooding Deficits In Memory: Focusing Attention Improves Subsequent Recall, Paula T. Hertel, Amanda A. Benbow, E. Geraerts

Psychology Faculty Research

Ruminative habits of thought about one’s problems and the resulting consequences are correlated with symptoms of depression and cognitive biases (Nolen-Hoeksema, Wisco, & Lyubomirsky, 2008). In our orienting task, brooders and nonbrooders concentrated on self-focusing phrases while they were also exposed to neutral target words. On each trial in the unfocused condition, participants saw and then reported the target before concentrating on the phrase; in the focused condition, the target was reported after phrase concentration. A brooding-related deficit on a subsequent unexpected test of free and forced recall was obtained in the unfocused condition only. Brooders recalled more successfully in …

Cusp Catastrophe Models For Cognitive Workload And Fatigue In A Verbally Cued Pictorial Memory Task, Stephen J. Guastello, Henry Boeh, Michael Schimmels, Hillary Gorin, Samuel Huschen, Erin Davis, Natalie E. Peters, Megan Fabisch, Kirsten Poston

Psychology Faculty Research and Publications

Objective: The aim of this study was to evaluate two cusp catastrophe models for cognitive workload and fatigue. They share similar cubic polynomial structures but derive from different underlying processes and contain variables that contribute to flexibility with respect to load and the ability to compensate for fatigue.

Background: Cognitive workload and fatigue both have a negative impact on performance and have been difficult to separate. Extended time on task can produce fatigue, but it can also produce a positive effect from learning or automaticity.

Method: In this two-part experiment, 129 undergraduates performed tasks involving spelling, arithmetic, memory, and visual …

The Longitudinal Stability Of Memory In Males With Autism Spectrum Disorder, Alexander J. Cramond

Theses and Dissertations

Previous research has demonstrated mixed evidence on impaired memory functioning in autism spectrum disorder (ASD), with the only consensus that there appears to be much heterogeneity. In addition, no research to date has examined the stability of memory in ASD. This study examined the stability of memory function in ASD compared to typically developing age-matched controls. Participants were administered the Test of Memory and Learning (TOMAL) twice, three years apart, in an established longitudinal NIH-supported investigation of ASD. Based on available research contrasting memory development in healthy individuals versus those with ASD, it was hypothesized that memory performance in the …

Behavioral And Fmri Evidence That Cognitive Ability Modulates The Effect Of Semantic Context On Speech Intelligibility, Adriana A Zekveld, Mary Rudner, Ingrid Johnsrude, Dirk J Heslenfeld, Jerker Rönnberg

Brain and Mind Institute Researchers' Publications

Text cues facilitate the perception of spoken sentences to which they are semantically related (Zekveld, Rudner, et al., 2011). In this study, semantically related and unrelated cues preceding sentences evoked more activation in middle temporal gyrus (MTG) and inferior frontal gyrus (IFG) than nonword cues, regardless of acoustic quality (speech in noise or speech in quiet). Larger verbal working memory (WM) capacity (reading span) was associated with greater intelligibility benefit obtained from related cues, with less speech-related activation in the left superior temporal gyrus and left anterior IFG, and with more activation in right medial frontal cortex for related versus …

Sensory And Cognitive Declines In Older Adults: A Longitudinal Study, Melanie Storm Bauer

All Theses and Dissertations (ETDs)

In a recent cross-sectional study, as has been found in numerous previous studies, Sommers et al.: 2011) found that age-related declines in hearing, as assessed by pure-tone thresholds, begin around age 20 and continue across the lifespan. In another article published from the same cross-sectional dataset, Hale et al.: 2011) found that working memory ability also begins declining around age 20 and continues throughout life. The present study is a longitudinal follow-up of these two studies in which a sub-sample of older adults: ≥65 years old at the time of original testing approximately four years ago) were re-tested on sensory …

Differences In Iq And Memory Of Monolingual/Bilingual Children Who Suffered A Tbi, Julie Alberty

Loma Linda University Electronic Theses, Dissertations & Projects

Pediatric traumatic brain injury (TBI) occurs at an average rate of 180 per 100,000 children who are hospitalized for head injury within the United States (Schwartz et al., 2003). Bilinguals are a large proportion of the population living in the United States and in Southern California, particularly. If children who are bilingual incur a TBI, will they have even more difficulty than monolinguals with language tasks because they have a smaller vocabulary base? This study aims to further elucidate whether verbal memory will be more severely impacted than nonverbal memory in this same bilingual pediatric TBI population. 18 children (M …

Construct And Criterion Validity Of The Rey Auditory Verbal Learning Test-Spanish Version In Adults With Traumatic Brain Injury, Cristobal Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Rey Auditory Verbal Learning Test (RAVLT) is among the most commonly used English-language neuropsychological tests of verbal learning and memory. Previous research supports the validity and clinical utility of adaptations of the RAVLT into many diverse languages. In the United States, Hispanics represent the largest and fastest-growing ethnic minority group. As the Hispanic populace continues to grow, so does the need for empirically validated Spanish-language neuropsychological measures. In 2002, a Spanish adaptation of the RAVLT was developed in Puerto Rico (Acevedo-Vargas, 2002). However, validation studies have not been undertaken with clinical samples, and little is known regarding its psychometric …
