Poor Stop-Signal Task Performance: Mechanisms Revealed through Event-Related Brain Potentials
(Vanderbilt University, 2010-04-07)
The stop-signal task has been used extensively in order to test abilities of inhibition as
well as cognitive functioning. In previous experiments, a relatively large number of
participants had to be excluded from analysis ...
Effects of Dopamine on Reward Learning in Parkinson’s Patients with Impulse Control Disorders
(Vanderbilt University, 2013)
This study investigated how dopamine agonist medication differentially affects reward learning in Parkinson’s patients with and without Impulse Control Disorders (ICDs). We tested 16 patients (8 female, 5 with ICDs, mean ...
The Effects of Priming on Reaction Times, Confidence Rating Measures, and Accuracy
(Vanderbilt University, 2016)
This project investigated the differences in reaction times between recognition of objects by feelings of familiarity and recognition of objects through direct recollection. Participants were shown images in a study phase, ...
A Study of Information Transfer between Long Term and Working Memory using Trans-Cranial Direct Current Stimulation at FCz
(Vanderbilt University, 2015-04-10)
Trans-cranial direct current stimulation (tDCS) is a method of electrical stimulation directed through a specific lobe or section of the brain in order to excite neurons and bring about a behavioral change. tDCS has ...
Behavioral Economics and Microfinance: A Study of Risk Preferences in Rural South Africa
(Vanderbilt University, 2011-04-05)
When deciding between safe and risky prospects, human decision-makers exhibit a number of framing effects. One of the most prominent of these effects, the reflection effect, is the tendency for decision makers to evaluate ...
Family Literacy across Three Generations of Undergraduate Students in Africa and the United States: Relation of Family Literacy Experiences on the Grade Point Averages of Undergraduate Students at the University of Botswana, University of Pretoria in South Africa, and Vanderbilt University in the United States
(Vanderbilt University, 2011-07-19)
The aim of this study was to describe literacy across three generations of undergraduate students (the students, their parents, and their grandparents) in Southern African (at the University of Pretoria and at the University ...
Transcranial direct-current stimulation (tDCS) on temporal lobe selectively affects the encoding of visual long-term memory
(Vanderbilt University, 2020-04-06)
Classical views of human visual long-term memory propose that people first encode the
visual stimuli into a long-term store, and then retrieve the visual information during task
period. In examining the temporal dynamics ...
Memory Encoding: The Costs and Benefits of Cueing
(Vanderbilt University, 2017-04-26)
This project investigated the benefits and costs of cueing on memory. Participants were shown images, some of which were cued as especially important to remember, in encoding blocks. The percentage of images cued changed ...

(Vanderbilt University, 2021-03-30)
The Effects of Control Processes and Continual Distraction on Recall Organization in Categorized Free Recall
(Vanderbilt University, 2021-04)
