Increasing Self-Testing Behavior In Students Using An Online Educational Intervention, Adam Patrick Young Jan 2018

Increasing Self-Testing Behavior In Students Using An Online Educational Intervention, Adam Patrick Young

Psychology and Neuroscience Graduate Theses & Dissertations

Self-testing is one of the most reliable and powerful memory benefits known to cognitive science. Unfortunately, many students omit this strategy in favor of less effective study techniques such as restudying. The superiority of self-testing to restudying is known as the testing effect (e.g., Roediger & Karpicke, 2006a). Applied interventions have been used to attempt to increase self-testing behaviors in student populations, but have so far been unable to draw strong conclusions due to the indirectness of their measurements and incompleteness of their experimental design. Furthermore, these past interventions have been conducted entirely in person, limiting their practical utility relative ...


Human Memory In A Modern World: Identifying The Cognitive Mechanism Behind Poor Memory For Digitally Available Information, Shane Ross Schwikert Jan 2017

Human Memory In A Modern World: Identifying The Cognitive Mechanism Behind Poor Memory For Digitally Available Information, Shane Ross Schwikert

Psychology and Neuroscience Graduate Theses & Dissertations

The emergence of the Internet, and its connected devices, are fundamentally changing the way we interact with information. New technology has created affordances that both lessen the burden on human memory and facilitate access to a nearly infinite amount of knowledge. In six experiments, the current research sought to determine how increasing interactions with technology are affecting memory, and to identify the cognitive mechanisms that are driving those changes. Experiments 1a, 1b, and 2 implemented modified item-method directed forgetting paradigms to examine how future access to information affects subsequent memory. Results indicated that explicit information about future availability delivered as ...

Functional Role Of Neural Oscillations In Attentional Inhibition And Long Term Memory Retrieval, Nicholas Ketz Jan 2016

Functional Role Of Neural Oscillations In Attentional Inhibition And Long Term Memory Retrieval, Nicholas Ketz

Psychology and Neuroscience Graduate Theses & Dissertations

How does the brain selectively retrieve information from long term memory? What neural mechanisms are critical for this process, and how are these mechanisms brought into service in a task dependent way? What are the implications for the representations that are processed through these mechanisms, and can we use our understanding of them to better utilize encoding and retrieval of information in long term memory? These are some of the fundamental questions being addressed in this dissertation. Through the use of neural network models of the hippocampus and surrounding cortex this dissertation proposes a framework for understanding how time frequency ...


Distributed Practice And Distributed Representations: Investigating The Spacing Effect Using Eeg, Matthew Via Mollison Jan 2015

Distributed Practice And Distributed Representations: Investigating The Spacing Effect Using Eeg, Matthew Via Mollison

Psychology and Neuroscience Graduate Theses & Dissertations

The spacing effect shows that studying information at distributed intervals leads to better long-term memory than massing study episodes together over the same cumulative amount of time. Prior research has not made explicit predictions about neural activity in the EEG domain that should occur at different study repetition lags under different spacing effect theories. One main purpose of this thesis is to make these predictions in terms of the neural activity expected under different spacing effect hypotheses, whereas another is to test these predictions. Knowledge about neural patterns underlying the spacing effect can shed light on why this effect occurs ...


Classifcation Aided Analysis Of Oscillatory Signatures In Controlled Retrieval, Nicholas Ketz Jan 2013

Classifcation Aided Analysis Of Oscillatory Signatures In Controlled Retrieval, Nicholas Ketz

Psychology and Neuroscience Graduate Theses & Dissertations

Control over memory retrieval is a ubiquitous process within humans, yet this process and its implications are not yet well understood. The current work, inspired by a similar fMRI design (Detre, Natarajan, Gershman, & Norman, in press), uses a modified Think/No-Think(TNT) paradigm to investigate the neural signatures of volition over enhancing and suppressing memory retrieval. Previous studies in this domain have shown a memory enhancement when well learned stimulus-pairs are restudied in cued recall (Think of studied pair item), and a degradation in memory performance when restudied with cued suppression (Dont think of studied pair item). As is the ...


The Clicker Technique: Promoting Learning And Generalization While Conserving Teaching Time, Lindsay Senior Anderson Jan 2010

The Clicker Technique: Promoting Learning And Generalization While Conserving Teaching Time, Lindsay Senior Anderson

Psychology and Neuroscience Graduate Theses & Dissertations

The clicker technique is a newly developed system that uses frequent testing in the classroom to enhance students’ understanding and provide feedback to them. Under the clicker technique, instructors can use the performance of a class on clicker questions to determine whether or not information covered by the clicker questions needs further teaching, thus presenting itself as a potential method of conserving teaching time by dropping information known by a large portion of a group from future teaching time. Three experiments compared fact learning under the clicker technique, via its tendency to compress teaching time and its partially individualized instruction ...
