Influence Of Seductive Details, Belief-Congruence, And Repeated Testing On Memory For Controversial Information, Daniel Adam Nuccio Sep 2014

Influence Of Seductive Details, Belief-Congruence, And Repeated Testing On Memory For Controversial Information, Daniel Adam Nuccio

Theses and Dissertations

People often encounter conflicting information on a wide array of topics. How they evaluate this information in relation to their current beliefs, and the effects of other influences, such as the weight given to superficial aspects of the information (e.g. pictures, anecdotes, or jargon that are at most minimally related to an author's argument), has been of interest to researchers for many years. One component of their processing

and evaluation of this information is their memory for the information. This study set out to examine the following questions: (1) Is belief-congruent in

formation remembered better or worse than ...


Memory Retrieval Is Maintained By Intrinsic And Synaptic Plasticity In Prelimbic Cortex, James Otis Aug 2014

Memory Retrieval Is Maintained By Intrinsic And Synaptic Plasticity In Prelimbic Cortex, James Otis

Theses and Dissertations

Abnormally strong memories underlie common disorders including addiction and post-traumatic stress disorder (PTSD). Memory disruption would therefore be beneficial for treatment of these disorders. Evidence reveals that cocaine conditioned place preference (CPP) memories are susceptible to long-lasting disruption during memory retrieval. For example, inhibition of β-adrenergic receptor (β-AR) activity within the prelimbic medial prefrontal cortex (PL-mPFC) prevents cocaine CPP memory retrieval, and this retrieval impairment is both long-lasting and prevents subsequent reinstatement of the CPP. Despite this, whether PL-mPFC β-AR activity is a fundamental mechanism required to maintain retrieval of other memories is unclear. Furthermore, how PL-mPFC β-AR activity maintains ...


Is Contextual Cue Learning Flexible? An Eye-Movement Study Of The Contextual Cueing Task, Youcai Yang May 2014

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 the ...


The Effects Of Focality Of Processing And Delay On Event-Based Prospective Memory, Samantha Nicole Petrella Apr 2014

The Effects Of Focality Of Processing And Delay On Event-Based Prospective Memory, Samantha Nicole Petrella

Theses and Dissertations

The current experiment proposes an examination of the effects of focality of processing and delays on event-based prospective memory tasks. Several perspectives regarding the process of remembering to perform an intended action in the future have been proposed by researchers in this area. Smith (2007) proposed the Preparatory Attentional and Memory (PAM) process theory regarding PM. According to the PAM theory, the retrieval of a prospective memory continuously requires resource-demanding preparatory attentional processes, or effortful and deliberate focus. Further, it suggests that successful PM retrieval is never automatic and that attention to the PM task interferes with and compromises ongoing ...


The Effect Of Sleep-Dependent Consolidation On Pattern Separation And Pattern Completion In Delayed Retrieval, Jesse Ray James Feb 2014

The Effect Of Sleep-Dependent Consolidation On Pattern Separation And Pattern Completion In Delayed Retrieval, Jesse Ray James

Theses and Dissertations

While people sleep, the brain replays the same neural firings that resulted from waking activities that day. This results in greater memory strength following a sleeping delay than a waking delay. The current project built upon this fact in a series of three experiments. Experiment 1. Although previous research has demonstrated a benefit of sleep to memory strength, the literature has not established the impact of sleep on memory specificity. Computational models of medial temporal lobe function posit that discrimination and generalization across similar memories are accomplished through processes known as pattern separation and pattern completion, respectively. To discover whether ...
