Investigations of the neural basis of source memory strength
… of the original experience. You may have a memory of the individual items you have encountered. We may also have memories of where those items came from, the source of those memories. Source memory includes elements regarding the perceptual or conceptual context of an item, such as the …

Event-related potential correlates of item and source memory strength
… potential (ERP) studies of recognition memory have shown dissociations between item recognition and source memory, wherein item recognition is associated with the mid-frontal FN400 component, which varies continuously with item memory strength, while source memory is associated with the …

When do eyewitness behaviors reflect the presence or absence of the culprit in a lineup?
… laboratory methodologies restricting eyewitness memory strength for the culprit. Accordingly, I exposed participant-eyewitnesses (N = 790) to a wide range of viewing conditions with the goal of increasing variability in both memory strength and postdictor variables. After viewing a simulated …

Drosophila CPEB, Orb2, a Putative Biochemical Engram of Long-term Memory
… experience creates an enduring yet dynamic memory remains a fundamental unresolved issue in studies of memory. Experience-dependent aggregation of the RNA-binding protein CPEB/Orb2 is one of the candidate mechanisms of memory maintenance. Here, using tools that allow rapid and reversible …

Remembering the past : multimodal imaging of cortical contributions to episodic retrieval
… temporal cortical structures that signal item memory strength, thus supporting the perception of item familiarity. Chapter 3 describes an fMRI experiment that demonstrated that retrieval of contextual details involves reactivation of neural patterns engaged at encoding.

Credibility of first versus second child sexual abuse allegations
… In cases where cognitive competence (e.g., memory strength) is more salient to an allegation, then older children are typically viewed as more believable than younger children, whereas in cases where honesty is more salient, then younger children are viewed as more believable than older …

A Repeated Forced-Choice Lineup Procedure: Examining the Impact on Child and Adult Eyewitnesses
… how each face in the lineup matches the witness’ memory of a target, relative to every other face. Results from Experiment 1 indicate that younger children (6-to-8-year-olds) struggled with the RFC procedure, while older children (9-to-11-year-olds) performed at least as well with the RFC …

The hidden-observer and memory creation
… between hidden-observer reports and pseudomemory. The study also investigated the rates of hidden-observer responses in age regression. During the screening session subjects were tested on (a) the Tellegen absorption scale (Tellegen, 1980, 1982), (b) The imagery scale of Paivo and …

Identifying Cognitive Profiles and Determinants of Cognitive Superaging Among Older Adults
… in 2012, 2016, and 2020. Five indicators of memory, attention, language fluency, and executive function informed latent profile analyses that yielded four interpretable profiles. These profiles included Cognitive superagers, a Memory strength profile, an Executive Function/Attention strength …

Source memory for actions
This thesis investigates source memory for performed and observed actions in recall and recognition tasks. The motor simulation account predicts that motor activation during action observation results in source misattributions of observed actions as self-performed. Alternatively, source judgements …

Development of Recognition Memory: Process Dissociation of Recollection and Familiarity in Children
… in the adult literature on whether recognition memory can better be explained by a single- or a dual-process account. Single-process accounts assume that a single memory strength signal underlies recognition. Dual-process accounts propose two independent processes, namely recollection (slow and …

Unexpected Arousal Suppresses Memory and Metamemory Predictions During Associative Face-Name Recognition Task
… often depends on probabilistic estimation of memory-signal. Arousal has been shown to offset the influence of heuristic evidence on memory prediction. We conducted three experiments that tested whether arousal also suppresses predictions relevant to memory confidence. Experiments employed …

Calcium-Stimulated Adenylyl Cyclases are Critical Modulators of Fear Learning and Experience-Dependent Plasticity
… of what modulates stress-facilitated memory processing will help identify new targets for possible therapeutic intervention. Recent evidence suggests a role of the Ca<super>2+</super>-stimulated adenylyl cyclases: AC), AC1 and AC8, in modulating fear memory. …

State-trace analysis of associative recognition: comparing single-process and dual-process models.
… associative recognition. Like recognition memory for individual items, associative recognition is currently understood through two different classes of model. The first is the single-process model class which holds that associative recognition decisions are based on a continuum of …

Sensitivity of relational memory representations to the factors of repetition, emotion, and context information
Episodic memory is the human cognitive faculty that enables humans to have a record of everyday events. Relational processing and representations are widely accepted to be the crucial underlying mechanism, implemented in the hippocampus, that support normal episodic memory function. As such, to …

Molecular and Neurochemical Effects of Methylphenidate on the Developing Brain
