Eyewitness Choosing Behavior: The Role Of Ecphoric Experience And Non-Memorial Cues, Brian S. Cahill
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 …
Building Metamemorial Knowledge Over Time: Insights From Eye Tracking About The Bases Of Feeling-Of-Knowing And Confidence Judgements, Elizabeth F. Chua, Lisa A. Solinger
Building Metamemorial Knowledge Over Time: Insights From Eye Tracking About The Bases Of Feeling-Of-Knowing And Confidence Judgements, Elizabeth F. Chua, Lisa A. Solinger
Publications and Research
Metamemory processes depend on different factors across the learning and memory time-scale. In the laboratory, subjects are often asked to make prospective feeling-of-knowing (FOK) judgments about target retrievability, or are asked to make retrospective confidence judgments (RCJs) about the retrieved target. We examined distinct and shared contributors to metamemory judgments, and how they were built over time. Eye movements were monitored during a face-scene associative memory task. At test, participants viewed a studied scene, then rated their FOK that they would remember the associated face. This was followed by a forced choice recognition test and RCJs. FOK judgments were less …
Variable Semantic Input And Novel First-Language Vocabulary Learning, Nichole Runge
Variable Semantic Input And Novel First-Language Vocabulary Learning, Nichole Runge
Arts & Sciences Electronic Theses and Dissertations
Vocabulary learning involves mapping a word form to a semantic meaning. An individual asked to learn the Spanish word for “apple,” for example, must map a new word form (manzana) onto the appropriate semantic representation. Previous studies have found that acoustic variability of word forms can improve second language vocabulary acquisition (Barcroft & Sommers, 2005; Sommers & Barcroft, 2007). The current experiments investigated whether variable semantic input could have a similar beneficial effect on first language vocabulary learning. Participants learned low-frequency English vocabulary words and their definitions. Half of the words were shown with the same verbatim definition …
Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang
Neural Correlates Of Episodic Memory Formation In Children And Adults, Lingfei Tang
Wayne State University Theses
The medial temporal lobe (MTL) and prefrontal cortex (PFC) are two key brain regions that support episodic memory formation in both children and adults, but the functional developmental of these regions remains unclear. In this study, we investigated the development of neural correlates of episodic memory formation using functional MRI with a subsequent memory paradigm, administered to a cross-sectional sample of 83 children and adults. We found that MTL subregions showed an age-related increase in activation supporting memory formation of complex scenes. In addition, a functionally defined scene-sensitive region in the posterior MTL also showed similar increase and predicted better …
Key Generalization Of Recognition Memory For Melodies, Abigail Lincoln Kleinsmith
Key Generalization Of Recognition Memory For Melodies, Abigail Lincoln Kleinsmith
Legacy Theses & Dissertations (2009 - 2024)
People easily recognize a melody in a previously unheard key, but they also retain some key-specific information. I tested the hypothesis that individuals compare novel melodies to a memory “prototype” representing the central tendency of experienced exemplars. Participants were familiarized with a monotonic eight-note melody in two closely separated keys and tested for discrimination of that melody from others. Test and foil melodies included ones that were the “average” of pitch heights and ones that were more distant in pitch height. Hit rates and discriminability (d') were better for physically closer keys than for harmonically related keys. In follow-up experiments, …
The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah
The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah
Theses and Dissertations (Comprehensive)
Numerous studies to date have demonstrated superior memory for emotional compared to neutral stimuli (Kensinger & Corkin, 2004; Bennion et al., 2013). This finding, although relatively stable across the item memory literature, becomes less consistent when examined in tasks measuring memory for associative or source information (Chiu et al., 2013). For this reason, the present study set out to examine how emotional content (negative, positive and neutral word pairs) influences memory in two distinct associative and item recognition tasks: associative identification (AI), associative reinstatement (AR), paired-item recognition, and single-item recognition. In measuring the influence of emotion on associations using an …
Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens
Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens
Walden Dissertations and Doctoral Studies
There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …
