Diagrams Benefit Symbolic Problem Solving
(Vanderbilt University, 2015-04-01)
How a problem is presented can influence students’ problem-solving performance. For example, including diagrams can alter students’ understanding, choice of strategy and accuracy on word problems. In this study, we examined ...
No Need For the Blindfold: The Influence of Perpetrator Attractiveness on Legal Decision-Making
(Vanderbilt University, 2010-04-21)
The idea that "justice is blind" has been called into question by some reports that attractiveness affects judgments of punishment and guilt. However, such studies are handicapped by a number of limitations, which this ...
Cladogram Curriculum: A First Look Into A Teaching Prototype For The Fundamentals Of Phylogenetics
(Vanderbilt University, 2010-04-07)
Past research has examined students’ comprehension of and reasoning with evolutionary relationships depicted by cladograms (i.e., tree thinking). Cladograms serve as a fundamental resource when studying macroevolution and ...
A Multilevel Logistic Regression Analysis on the Likelihood of Overeating and Unplanned Eating
(Vanderbilt University, 2017-04)
This paper analyzed three models of emotional eating: the restraint disinhibition model, the affect-regulation model, and the externality model (Herman and Polivy, 1975; Haedt-Matt & Keel, 2011; Schachter, 1968). Emotional ...
Causes of Interference: Working Memory and Distraction
(Vanderbilt University, 2011-02-06)
Working memory accounts for various types of cognitive processing, including object and spatial processing. Distraction has been demonstrated to be domain-specific with the strongest interference coming from a distractor ...

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 ...
