40 Hz Gamma Sensory Stimulation Effects on Memory Performance in Cognitively Healthy Older Adults
(Georgia Institute of Technology, 2022-04)
Recent studies have demonstrated that a gamma sensory stimulation, light and sound flickering at 40 Hz, decreased Alzheimer’s symptoms and pathology in mice. Subsequent human trials showed similar results. Here we focus ...
Examining Social Influence's Effect on Decision-Making and Bayesian Truth Serum
(Georgia Institute of Technology, 2022-04-28)
Decision-making—whether individual or in groups—can be subject to revision based on social influence, often pulling one’s opinions towards the apparent consensus (Mason, Conrey, & Smith, 2007). Social influence has been ...
The effect of retrospective attention on memory systems
(Georgia Institute of Technology, 2015-04-09)
Prior research has shown that visual working memory (VWM) performance can be improved via retrospective cues (“retro-cues”) that spatially indicate which item currently being held in working memory will be probed at test. ...
Individual differences in signed word learning among hearing adults
(Georgia Institute of Technology, 2016-12-01)
The present study was conducted in order to identify predictors of signed word learning in hearing non-signers. 107 hearing non-signing adults participated, completing a sign-word paired associate learning task, two ...
Understanding younger and older adults' perceptions of humanoid robots: effects of facial appearance and task
(Georgia Institute of Technology, 2013-05-15)
Although humanoid robots are being designed to assist people in various tasks, there remain gaps in our understanding of the perceptions that humanoid faces evoke in the user. Understanding user perceptions would help ...
Neural mechanisms for stimulus-response preparation
(Georgia Institute of Technology, 2014-10-29)
Human behavior relies on the accumulation of task-relevant information to narrow the range of possible responses to a single response. How do we utilize advance information that can help us select and prepare responses to ...
The relationship between basal cortisol levels and cognitive functioning across the adult lifespan
(Georgia Institute of Technology, 2016-05-03)
Age-related declines in cognitive functioning have been well documented, however, there are vast individual differences in the age of onset and magnitude of these changes. This observation has spurred the investigation of ...
Optimizing military planners course of action decision making
(Georgia Institute of Technology, 2019-05-23)
Military planners are faced with ever-increasing constraints, obstacles, and priority readjustments during the course of action (COA) development. This upward trajectory places a more demanding cognitive workload on decision ...
Age-related differences in fraction comparison: A process level approach
(Georgia Institute of Technology, 2014-04-10)
This study is an investigation into the relationship between numeric cognition and aging. Specifically, older and younger adults engaged in an experimental protocol that allowed observation of number comparison accuracy ...
The role of situational strength in organizational attraction: an interactionist approach
(Georgia Institute of Technology, 2013-10-15)
Organizational environment (broadly conceptualized) has been shown to have an important influence on job choice (Chapman, Uggerslev, Carroll, Piasentin & Jones, 2005). Controversy exists, however, regarding how to ...
