The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski
The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski
UNLV Theses, Dissertations, Professional Papers, and Capstones
Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …
Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley
Effects Of Top-Down Attention And Individual Differences On Recognition Memory And Recollective Experience., Anna Kelley
Electronic Theses and Dissertations
Memory accuracy and detail hold practical importance, and psychology has studied means to improve memory. One such means is performing visually guided saccades immediately before a memory test. Previous work has found this intervention to improve memory performance, an effect dubbed Saccade-Induced Retrieval Enhancement or SIRE. The top-down attentional control account posits that SIRE occurs because saccades activate attentional control regions in the brain, which contributes to executing top-down attentional control when searching memory. The current experiment tested this account of SIRE by attempting to replicate previous results and investigating whether a different attentional task, the Revised Attention Network Test …
Binge-Watching And The Spacing Effect, Michael R. Austin
Binge-Watching And The Spacing Effect, Michael R. Austin
Masters Theses, 2020-current
Binge-watching, defined as consuming at least three episodes or three hours of video media in one sitting, is an increasingly prevalent behavior in the digital age. But scant research exists investigating how binge-watching affects memory for what was watched. Literature surrounding the spacing effect, defined as superior memory for information presented repeatedly across longer spans of time, would predict a memory deficit for binged material. However, findings from previous unpublished research by Fogler and colleagues do not align with this prediction. To investigate the dissonance, the aim of this research is to replicate and extend the work of Fogler and …
An Eeg Study On Loneliness And Recognition Memory, Carmen Jia Wen Chek
An Eeg Study On Loneliness And Recognition Memory, Carmen Jia Wen Chek
Electronic Theses and Dissertations
Loneliness, the perception of unmet social needs, has been shown to relate to recollection-based recognition deficits, but the relationship between loneliness and recognition memory (i.e., recollection and familiarity) has not been thoroughly examined. The current study hypothesized that more lonely individuals would have lower recognition memory performance, specifically recollection, with smaller ERP parietal old-new effects than less lonely individuals. Forty participants, grouped into less (n = 13) and more (n = 9) lonely groups based on their R-UCLA responses, completed an associative memory task. EEG was used to assess recognition memory effects. Results showed no significant difference in …
Do Distractor Suppression And Learning Intentionality Contribute To The Attentional Boost Effect?, Stephanie C. Crocco
Do Distractor Suppression And Learning Intentionality Contribute To The Attentional Boost Effect?, Stephanie C. Crocco
Legacy Theses & Dissertations (2009 - 2024)
In the Attentional Boost Effect (ABE), a target-detection response enhances memory for simultaneously presented unrelated stimuli (Swallow & Jiang, 2010; see Swallow & Jiang, 2013 for a review). In two experiments, participants read aloud words simultaneously presented with a dot. Trials were presented every 1150 ms (Experiment 1) or every 2200 ms (Experiment 2). In a divided attention (DA) task, participants made a key-press to dots of a specific color. In a full attention (FA) task, they only read the words aloud while ignoring all dots. Under either intentional or incidental learning instructions, the DA task included Target words, and …
Testing Recognition Memory Models With Forced-Choice Testing, Qiuli Ma
Testing Recognition Memory Models With Forced-Choice Testing, Qiuli Ma
Masters Theses
People’s ability to call an experienced item “old” and a novel item “new” is recognition memory. Recognition memory is usually studied by first asking participants to learn a list of words and then make judgments of old (studied) or new (not studied) for test words. It has long been debated whether the underlying process of recognition memory is continuous or discrete. Two types of models are compared specifically that assume either discrete or continuous information states: the 2-high threshold (2HT) model and the unequal variance signal detection (UVSD) model, respectively. Researchers have used the receiver operation characteristic (ROC) function and …
The Effect Of Incentives On Pupil Dilation During Recognition Memory: An Attentional Saliency Account Of The Pupil Old/New Effect, Lisa A. Solinger
The Effect Of Incentives On Pupil Dilation During Recognition Memory: An Attentional Saliency Account Of The Pupil Old/New Effect, Lisa A. Solinger
Arts & Sciences Electronic Theses and Dissertations
Another interesting feature of this OMS circuit is the strong surround suppression occurring in the inner retina, which enables both VG3-ACs and W3-RGCs to remain silent to the global image motion. Pharmacological evidence suggested wide-field and/or spiking ACs are the source of the inhibition. The specific AC types, however, have not been identified. To address this question, in chapter 3, I explored candidate cell types using transgenic mouse lines expressing Cre recombinase, mainly tyrosine hydroxylase (TH)-Cre transgenic mice. In 2-photon guided patch clamp recordings, response patterns of TH2-ACs to object motion visual stimuli corresponded to inhibitory inputs of both VG3-ACs …
Not Just Noise: Individual Differences In Cognitive Ability And Response Bias, Tina Chen
Not Just Noise: Individual Differences In Cognitive Ability And Response Bias, Tina Chen
Doctoral Dissertations
Response bias is a component of decision making that can be defined as the general willingness to respond a certain way. For example, in recognition memory, one can have a response bias towards responding that a test item has been previously studied, or in reasoning, one can have a response bias towards responding that a conclusion is logically valid. However, not all individuals have the same response bias. Indeed, there is some evidence that response bias is a stable cognitive trait in memory that differs across individuals (Kantner & Lindsay, 2012, 2014). One predictor of this trait may be cognitive …
Methods Of Measuring Visual Scanning Of Upright And Inverted Ecological Images, Benjamin Lee Graves
Methods Of Measuring Visual Scanning Of Upright And Inverted Ecological Images, Benjamin Lee Graves
MSU Graduate Theses
Facial recognition has been long held as a special perceptual process at which humans excel, and is primarily a function of perceptual experience. However, there are experimental manipulations that impede this perceptual process and make it more difficult for humans to recognize the face (i.e. only presenting half a face or inverting the face). In the case of inversion, it is though that the inverted face interrupts a person's ability to process the face holistically and forces a change to featural processing. The purpose of this experiment was to examine if inversion of ecologically valid images would also impact recognition …
Are There Multiple Kinds Of Episodic Memory? An Fmri Investigation Comparing Autobiographical And Recognition Memory Tasks, Hung-Yu Chen
Are There Multiple Kinds Of Episodic Memory? An Fmri Investigation Comparing Autobiographical And Recognition Memory Tasks, Hung-Yu Chen
Arts & Sciences Electronic Theses and Dissertations
What brain regions underlie retrieval from episodic memory? The bulk of research addressing this question has relied upon laboratory-based recognition memory. Another, less dominant tradition has employed autobiographical methods, whereby people recall events from their lifetime, often after being cued with words or pictures. Previous research comparing regions underlying successful memory retrieval between these two methodological approaches has shown mixed results. To examine the neural processes underlying recognition memory for materials encountered in the laboratory and autobiographical memory, we conducted a within-subject study using fMRI. We showed participants indoor and outdoor scenes under two types of instructions: In the lab-based …
Rapid Detection And Use Of Non-Verbal Confidence Cues During Adaptive Memory Biasing, Jihyun Cha
Rapid Detection And Use Of Non-Verbal Confidence Cues During Adaptive Memory Biasing, Jihyun Cha
Arts & Sciences Electronic Theses and Dissertations
Prior literature has demonstrated that participants use probabilistic, verbal memory cues (‘Likely Old’ or ‘Likely New’) to adaptively bias their recognition judgments. Here we tested whether this is more effective when the cues are the actual videotaped responses of others taking the same recognition test, based on the possibility that observers might use non-verbal confidence signs to modulate their degree of cue reliance on each trial. Experiment 1 demonstrated observers could reliably rate the confidence of others (Models) from single recognition responses (‘old’ or ‘new’) and that when doing so, the latency of the model’s response was the primary influence, …
Bayesian Models Of Sequential Dependencies In Binary And Multi-Interval Response Tasks, Jeffrey Scott Annis
Bayesian Models Of Sequential Dependencies In Binary And Multi-Interval Response Tasks, Jeffrey Scott Annis
USF Tampa Graduate Theses and Dissertations
A sequential dependency occurs when the response on the current trial is correlated with responses made on prior trials. Sequential dependencies have been observed in a variety of both perception and memory tasks. Thus, sequential dependencies provide a platform for relating these two cognitive processes. However, there are many issues associated with measuring sequential dependencies and therefore it is necessary to develop measurement models that directly address them. Here, several measurement models of sequential dependencies for both binary and multi-interval response tasks are described. The efficacy of the models is verified by applying them to simulated data sets with known …
Selective Effects Of Selective Attention, Katherine Camille Moen
Selective Effects Of Selective Attention, Katherine Camille Moen
Seton Hall University Dissertations and Theses (ETDs)
Selective Attention is the process by which an individual attends to one stimulus while ignoring other distracting stimuli. Selective attention at encoding has been found to consistently impair memory performance. However, little research has found conclusive evidence as to the impact of selective attention during initial retrieval, and how that impacts retrieval on later tests, or the influence of the types of stimuli that participants are ignoring. The following series of experiments outline how selective attention impairs memory immediately and after a delay, during encoding and retrieval. Experiments 1-3 manipulated attention during retrieval. Experiment 1 found that selective attention during …
Feedback As A Source Of Criterion Noise In Recognition Memory, Bryan Franks
Feedback As A Source Of Criterion Noise In Recognition Memory, Bryan Franks
LSU Master's Theses
In two experiments, I investigated whether providing accuracy feedback on recognition memory tests affects discriminability of encoded targets from lures. The primary hypothesis was that feedback is a source of criterion noise which leads to lower discriminability. Additionally, it was predicted that separate sources of criterion noise might have additive effects. In both experiments, the presence of feedback was manipulated within-subjects. In Experiment 1, participants completed two recognition tests in which they made either “old/new” decisions or responded using an 8-point confidence scale. Feedback lowered discriminability for both response type conditions, although a slightly larger deleterious effect was observed in …
Examining The Testing Effect Using The Dual-Process Signal Detection Model, Nicole Jessica Bies-Hernandez
Examining The Testing Effect Using The Dual-Process Signal Detection Model, Nicole Jessica Bies-Hernandez
UNLV Theses, Dissertations, Professional Papers, and Capstones
Taking a test can lead to enhanced long-term retention compared to not practicing the information or simply restudying, a finding known as the testing effect (Roediger, Agarwal, Kang, & Marsh, 2010). The current study examined whether the dual-process signal detection (DPSD) model (Yonelinas, 1994) offers an approach for investigating the testing effect across two experiments. Experiment 1 investigated if the DPSD model could be used to examine the testing effect, and it also examined a factor (i.e., the number of practice sessions) that influences the magnitude of the testing effect. Experiment 2 investigated whether making the final test dependent on …
A Model Of Positive Sequential Dependencies In Judgments Of Frequency, Jeffrey Scott Annis
A Model Of Positive Sequential Dependencies In Judgments Of Frequency, Jeffrey Scott Annis
USF Tampa Graduate Theses and Dissertations
Positive sequential dependencies occur when the response on the current trial n is positively correlated with the response on trial n-1. This was recently observed in a Judgment of Frequency (JOF) task (Malmberg and Annis, 2011). A model of positive sequential dependencies was developed in the REM framework (Shiffrin & Steyvers, 1997) by assuming that features that represent the current test item in a retrieval cue carry over from the previous retrieval cue. To assess the model, we sought a set of data that allows us to distinguish between frequency similarity and item similarity. Therefore, we chose to use a …
Sac Attack: Assessing The Role Of Recollection In The Mirror Effect, Angela M. Pazzaglia
Sac Attack: Assessing The Role Of Recollection In The Mirror Effect, Angela M. Pazzaglia
Open Access Dissertations
Low-frequency (LF) words have higher hit rates (HRs) and lower false alarm rates (FARs) than high-frequency (HF) words in recognition memory, a phenomenon termed the mirror effect by Glanzer and Adams (1985). The primary mechanism for producing the mirror effect varies substantially across models of recognition memory, with some models localizing the effects during encoding and others during retrieval. The current experiments contrast two retrieval-stage models, the Source of Activation Confusion (SAC; Reder, Nhouyvanisvong, Schunn, Ayers, Angstadt, & Hiraki, 2000) model and the unequal variance signal detection theory (UVSDT) criterion shift model (e.g., DeCarlo, 2002). The SAC model proposes that …
Contributions Of Signal-Detection Mechanisms And Semantic Memory Representations To Famous Name Recognition, Ben P. Bowles
Contributions Of Signal-Detection Mechanisms And Semantic Memory Representations To Famous Name Recognition, Ben P. Bowles
Electronic Thesis and Dissertation Repository
In past research, investigators have often used the recognition memory paradigm to study the cognitive and neural processes that permit the ability to accurately assess whether or not stimuli are familiar. This paradigm involves presenting stimuli to participants in a study phase, and examining their later recognition of them when these stimuli are subsequently presented again in a later test phase. It is not well understood, however, whether the same mechanisms that support familiarity assessment in recognition memory also support familiarity based on general life experience (e.g., recognizing a famous celebrity in daily life). To address this, I implemented modified …
Source Memory, Subjective Awareness, And The Word Frequency Mirror Effect, Benjamin A. Martin
Source Memory, Subjective Awareness, And The Word Frequency Mirror Effect, Benjamin A. Martin
LSU Master's Theses
The current study investigated the subjective states of recollection and familiarity in source memory. Participants studied low and high frequency words, presented in one of two sources, and were then asked to make source decisions and subjective judgments of recollection and familiarity at test. Half of participants were asked to identify the source of an item before the subjective awareness judgment (SM-first group), while the other half of participants made a source decision to an item after judging it as recollected or familiar (RF-first group). The test order manipulation affected participants’ patterns of responding. Participants in the RF-first group tended …
Source Memory And The Picture Superiority Effect, Noelle L. Brown
Source Memory And The Picture Superiority Effect, Noelle L. Brown
LSU Master's Theses
Two experiments were conducted to explore whether a picture superiority effect exists in source memory. To investigate this issue, participants studied a mixed list of pictures and words. Experiment 1 tested people's memory for an organizational source where half the pictures and words were studied on the left or right side of a computer monitor. In Experiment 2 an associative source was tested. During encoding half of the pictures and words were associated with a female voice and the other half with a male voice. At test, participants' memory for the location or voice of the pictures and words was …
The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns
The Effects Of Internal And External Context Reinstatement On Source Memory, Jeffrey Joseph Starns
LSU Master's Theses
Memory for attended aspects of an encoded event (item memory) is facilitated when features of the encoding context are reinstated at test, indicating that item and context features are bound together in memory traces (Smith, 1979). The present study investigated whether reinstated contextual features similarly enhance memory for other contextual details of an event (source memory). Participants studied words that appeared on either the top or bottom of the computer screen in either a large or small font size. Following the study phase, participants completed a recognition/source test in which they had to indicate the location in which they studied …
