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 ... -
CHARACTERISTIC LAG & THE INTERMANUAL SPEED ADVANTAGE
(Georgia Institute of Technology, 2022-01-24)Previous research has found evidence for the intermanual speed advantage, wherein novice actors perform a visually-guided, two-handed task faster with one hand from each member of a dyad (i.e., intermanually) compared to ... -
Individual Differences in Deepfake Detection: Mindblindness and Political Orientation
(Georgia Institute of Technology, 2021-01-14)The proliferation of the capability for producing and distributing deepfake videos threatens the integrity of systems of justice, democratic processes, and the general ability to critically assess evidence. This study ... -
Vertical Equating with Longitudinal Data: Unidimensional and Multidimensional Item Response Theory Models
(Georgia Institute of Technology, 2020-10-20)Vertical equating is one context in which item response theory (IRT) model fit is important to evaluate and the measurement of change in students’ performance between test occasions is a central topic in educational research ... -
Impacts on performance effectiveness, processing efficiency, and subjective experience by music listening in extraverts and introverts
(Georgia Institute of Technology, 2021-12-14)The present study evaluates the utility of a new model based on attentional control theory (ACT) in a music psychology study. This new model seeks to provide a mechanism to explain impacts of concurrent-task music listening ... -
Subgoal Level Feedback Benefits Novel Problem Solving
(Georgia Institute of Technology, 2021-12-14)The present study combined subgoal learning and feedback frameworks to further improve problem solving performance and demonstrated that subgoal level feedback resulted in better learning outcomes over step level feedback, ... -
The Effects of Output Interference on Metamemory and Cued Recall Accuracy in Young and Older Adults
(Georgia Institute of Technology, 2021-12-13)Output interference (OI) is a gradual decline in memory accuracy as a function of an item’s position in a testing sequence (Anderson & Neely, 1996). Despite having been researched for over 50 years (e.g., Tulving & Arbuckle, ... -
The Influence of Testing on Memory for Context
(Georgia Institute of Technology, 2021-11-03)Employing different types of testing is a useful tool for studying changes in item memory, but this tool has sparsely been leveraged to study changes in memory for contextual information. Memory for contextual information ... -
Change Detection as a Framework for Understanding Individual Differences in Attention Control and Allocation of Attention Across the Visual Field
(Georgia Institute of Technology, 2021-10-22)Attention control is a domain-general ability that guides the control of thoughts and intentional behavior in a goal-driven manner and is a central concept to many models of human cognition. Our lab recently showed that ... -
FRAME ANALYSIS: A MODERN APPROACH TO FACTOR ANALYSIS
(Georgia Institute of Technology, 2021-11-11)We introduce and develop a new statistical method for exploring latent structures: Frame Analysis. Frame Analysis drops the one-to-one correspondence between factor dimensionality and vector space representation found in ... -
The Role of Basal Cortisol Elevations in Alzheimer’s Disease: Presence and Prediction of Associated Pathology
(Georgia Institute of Technology, 2020-08-04)Elevations in the glucocorticoid steroid hormone cortisol have long been suspected to be characteristic of Alzheimer’s disease, and there is a renewed interest in the contribution of cortisol to the progression of the ... -
The Impact of Criterion Shifts on Evidence Accumulation in the Inferior Temporal Cortex
(Georgia Institute of Technology, 2021-08-09)Decision-making is a cognitive process that occurs in stages and can be conceptualized by variations of sequential sampling models which suggest that, for the options in a binary forced-choice decision-making task, there ... -
Cross-modal schema effect of music pairing on shape sequence acquisition
(Georgia Institute of Technology, 2021-07-14)Music is a multidimensional sequence of pitches and temporal intervals that has a predictable structure over time. Prior literature has revealed that humans are innately equipped to learn and anticipate these pitches and ... -
Dissociating the brain regions involved in processing objective and subjective performance
(Georgia Institute of Technology, 2021-08-02)When making perceptual decisions, easier tasks produce higher task accuracy and, naturally, higher confidence levels. We recognize the two distinctive cognitive processes, but it is challenging to judge exactly how decision ... -
Neural Correlates of Emotional Memory as a Function of Age and Depressive Symptoms
(Georgia Institute of Technology, 2021-07-29)Age-related positivity effects are well established in the literature. Positivity effects in memory are represented as greater benefits for positive over neutral material and/or reductions in the benefits for negative over ... -
A Large Online Study Examining Individual Differences in Sleep Quality and Episodic Memory Performance Across the Adult Lifespan: Interactions Between Psychosocial and Sociodemographic Factors
(Georgia Institute of Technology, 2021-07-30)The relationship between sleep quality and episodic memory performance, or memory for the details of past events, has been established in young and older adults. Although the sleep-memory relationship is similar across age ... -
Creativity, Depression, and Rumination
(Georgia Institute of Technology, 2021-06-25)Among creative professionals, affective vulnerability and diagnosed mood disorders are higher than would be expected in the general population (Ludwig, 1995). Rumination, that is, a broad class of thoughts that recur ... -
Distinguishing the roles of dorsolateral and anterior PFC in visual metacognition
(Georgia Institute of Technology, 2021-07-22)Visual metacognition depends on regions within the prefrontal cortex. Two areas in particular have been repeatedly implicated: the dorsolateral prefrontal cortex (DLPFC) and the anterior prefrontal cortex (aPFC). However, ... -
Modernizing Transportable Teamwork Competency Training
(Georgia Institute of Technology, 2021-05-01)Generic teamwork competencies have been researched and discussed for the last 30 years and these competencies are often the focus of determining an employee’s ability to work in a team While most of these competencies hold ... -
