Mechanisms Of False Memories In Bilinguals, Bianca Valentina Gurrola

Open Access Theses & Dissertations

Research on false memory in bilinguals has discovered that false memories can transfer across languages and occur at a higher rate than for within-language false memories (Marmolejo et al., 2009). However, the exact conditions that cause the stronger between-language false memory effect are not clear, nor is it clear how language proficiency influences the production of false memories. The present study had three goals. First, we tested whether the stronger between- language false memory effect relative to the within-language effect would replicate. Second, we examined whether bilinguals could integrate information across languages to form false memories by implementing a mixed-language …

The Effects Of Divided Attention In Free Recall: Affecting Trace Accumulation By Dividing Attention, Anne Olsen

USF Tampa Graduate Theses and Dissertations

How environmental information stores in memory directly affects our ability to retrieve the information. This thesis investigates the effects that dividing attention during study has on the storage of contextual information. Through several experiments, participants were asked to study and later recall word lists using a mixed-pure design with strengtheners varying as either repetition or study time. Experiment 1 investigates the effects of divided attention on the formation of inter-item associations and Experiments 2-6 manipulate strengthening item and context information in a memory trace when cognitive load is strained at various levels. Experimental results indicated that dividing attention during study …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

Behavioral, Physiological, And Molecular Characterization Of Long-Term Administration Of A Novel Estrogen Receptor Beta Agonist In A Mouse Model Of Menopause, Aaron William Fleischer

Theses and Dissertations

The menopausal loss of circulating hormones, including estrogens, is associated with negative symptoms, such as hot flashes, anxiety and depression, cognitive decline, and weight gain. Although estrogenic hormone therapies (HT) prevent many of the negative symptoms related to the menopausal transition, these same therapies are associated with increased health risks, such as the development of breast and ovarian cancers, which is mediated by the activation of the a (ERa), but not b (ERb), estrogen receptor isoform. Furthermore, ERb agonism has previously been shown to reduce preclinical indices of hot flashes, memory decline, anxiety, and depression. As most ERb agonists are …

A Field Study Examining The Effect Of High Intoxication Levels And Identification Format On Witnesses' Memory For Faces And Events, Christopher Altman

FIU Electronic Theses and Dissertations

Members of the legal system (e.g., experts, jurors, investigators) are often skeptical of the information provided by intoxicated witnesses given the negative stigma surrounding alcohol and memory. However, studies examining the relationship between alcohol and witness memory often find that alcohol has no effect on peoples’ recall or their ability to identify a previously seen face. While insightful, the validity of these findings has been questioned given the low-moderate blood alcohol concentration (BAC) levels tested in these predominantly laboratory-based studies, which may not be high enough to consistently expose the cognitive deficits alcohol is expected to create. The present study …

Motivational Valence Alters Memory Formation Without Altering Exploration Of A Real-Life Spatial Environment, Kimberly S. Chiew, Jordan Hashemi, Lee K. Gans, Laura Lerebours, Nathaniel J. Clement, Mai-Anh T. Vu, Guillermo Sapiro, Nicole E. Heller, R. Alison Adcock

Psychology: Faculty Scholarship

Volitional exploration and learning are key to adaptive behavior, yet their characterization remains a complex problem for cognitive science. Exploration has been posited as a mechanism by which motivation promotes memory, but this relationship is not well-understood, in part because novel stimuli that motivate exploration also reliably elicit changes in neuromodulatory brain systems that directly alter memory formation, via effects on neural plasticity. To deconfound interrelationships between motivation, exploration, and memory formation we manipulated motivational state prior to entering a spatial context, measured exploratory responses to the context and novel stimuli within it, and then examined motivation and exploration as …

Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, Jeffrey R. Stevens, Jan K. Woike, Lael J. Schooler, Stefan Lindner, Thorsten Pachur

Jeffrey Stevens Publications

Analyses of the evolution of cooperation often rely on two simplifying assumptions: (i) individuals interact equally frequently with all social network members and (ii) they accurately remember each partner's past cooperation or defection. Here, we examine how more realistic, skewed patterns of contact—in which individuals interact primarily with only a subset of their network's members—influence cooperation. In addition, we test whether skewed contact patterns can counteract the decrease in cooperation caused by memory errors (i.e. forgetting). Finally, we compare two types of memory error that vary in whether forgotten interactions are replaced with random actions or with actions from previous …

Rescuing Age-Related Proteolysis Deficits With Methylene Blue, Shane E. Pullins

Theses and Dissertations

The average lifespan is constantly increasing with the advent of new medical techniques, and age-related cognitive decline is becoming a prevalent societal issue. Even during healthy aging, humans and rats exhibit progressive deficits in episodic/declarative memory. In laboratory rats, age-related memory impairment can be assessed with trace fear conditioning (TFC). Recent research implicates ubiquitin proteasome system-mediated protein degradation in the synaptic plasticity supporting memory formation and retrieval. In rats, aging leads to decreased basal proteolytic activity in brain structures known to support the acquisition and retrieval of trace fear memories, and our preliminary data suggests activity-dependent proteasome activity declines in …

Eliciting A Perpetrator Description Using The Cognitive Interview: Influences On Investigative Utility, Geri Satin

FIU Electronic Theses and Dissertations

The Cognitive Interview (CI) has been shown in over one hundred studies to enhance eyewitness recall. However, no study has explored whether the CI improves police job performance. The current study was the first to test the practical value of the CI in a criminal investigation, testing participants’ performance on key police tasks using either a perpetrator description elicited from a CI or from a standard police interview (SI).

In an earlier study, student witnesses were exposed to a simulated robbery and were then interviewed using either a CI or an SI to elicit a description of the robber (comprised …

Is Cooperative Memory Special? The Role Of Costly Errors, Context, And Social Network Size When Remembering Cooperative Actions, Jeffrey R. Stevens, Tim Winke

Jeffrey Stevens Publications

Theoretical studies of cooperative behavior have focused on decision strategies, such as tit-for-tat, that depend on remembering a partner’s last choices. Yet, an empirical study by Stevens et al. (2011) demonstrated that human memory may not meet the requirements that needed to use these strategies. When asked to recall the previous behavior of simulated partners in a cooperative memory task, participants performed poorly, making errors in 10–24% of the trials. However, we do not know the extent to which this task taps specialized cognition for cooperation. It may be possible to engage participants in more cooperative, strategic thinking, which may …

Source Monitoring In Bilinguals, Renee Michelle Penalver

Open Access Theses & Dissertations

Source memory is memory for the context in which a particular target item is learned (Parker, 1995). The source-monitoring framework is the leading model of source memory (Johnson, Hashtroudi, & Lindsay, 1993). It remains unknown at what level context-to-word associations are made (e.g., at the word form level or conceptual level). Three experiments examined the effects of word frequency and language proficiency on source memory, with each experiment addressing one of the different types of source monitoring identified in this framework. In Experiment 1, we examined how language proficiency and word frequency affect external source discrimination. Participants had to discriminate …

Music And Memory: A Qualitative Look At How Music Affects Episodic Memory, Jonathan A. Coad

Honors Undergraduate Theses

This study was designed to examine qualitative data regarding gender and age differences about significant life events that are recalled when music is remembered. Two groups of participants were recruited, younger adults (M = 19.78, SD = 4.99) and older adults (M = 49.31, SD = 8.72). Data were collected by creating a survey and allowing participants to choose whichever songs, from their own experience, they like and asking them to list detailed memories that are attached to the song. Using the Linguistic Inquiry Word Count (2015) software, data was coded into categories of word count, positive and negative emotions, …

Eyewitness Choosing Behavior: The Role Of Ecphoric Experience And Non-Memorial Cues, Brian S. Cahill

FIU Electronic Theses and Dissertations

Researchers’ attempts at understanding the processes underlying witness choosing behavior have focused on applying models that predict that identifications will be primarily driven by memorial factors. However, research has shown that several non-memorial variables affect witness choosing behavior (e.g., administrator influence, clothing bias, co-witness information); thus a full understanding of the processes underlying witness choosing behavior needs to account for these effects. While the memory-based models do attempt to provide explanations for the effects of non-memorial based variables on choosing behavior they all do so within a memorial context. However, I will argue a lineup task is not simply a …

Attentional Competition: Weapon Focus, Encoding Time, And Memory Accuracy Correlations Between Crime Scene Items, Seyram Kekessie

FIU Electronic Theses and Dissertations

The present study examines the relationships between recognition and recall accuracy of faces, and recognition and recall accuracy of objects. Secondly, this study examines the influence of weapon presence on description and identification accuracy, and whether encoding time moderates the effect. 713 participants watched an image that was either displayed for five seconds or twenty seconds, and either included a weapon or no weapon. Subsequently, they were asked to give descriptions of what they saw before viewing a lineup that either included the perpetrator or was made up of innocent suspects. Results indicated that witnesses’ description accuracy of the crime …

Is Contextual Cue Learning Flexible? An Eye-Movement Study Of The Contextual Cueing Task, Youcai Yang

Theses and Dissertations

Visual searching can be facilitated without awareness when the target is repeatedly presented in an invariant context in tasks such as contextual cueing (Chun & Jiang 1998). A behavioral cost (increased reaction time) was observed when the target was moved to a new location but no such cost was observed when the target returned to the initial location. The lack of cost for return suggests two possible explanations: One is that the learning can update the initial learning to acquire both target locations, which suggests the implicit learning is flexible. The other is that the contextual cue leaning cannot update …

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.

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 …

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 …
