Dimensionality assessment of proximity-based data in unfolding model applications
(Georgia Institute of Technology, 2015-04-09)Dimensionality assessment of measurement instruments in psychology is no easy task. Within the field of IRT, much attention has been given to the issue of dimensionality assessment for item responses that are consistent ... -
Routes to organizational influence: the facets of political skill and social network centrality
(Georgia Institute of Technology, 2015-02-24)Political skill describes an individual’s ability to successfully navigate the political arena of organizations (Ferris et al., 2007). The present study tested whether political skill and its four dimensions (i.e., social ... -
Engineering visual displays to influence choice in automated decision support systems
(Georgia Institute of Technology, 2018-07-11)The task of choosing between decision alternatives presented on a visual display is ubiquitous. Automated decision support systems (DSS) provide a powerful means of improving human decision-making outcomes, but they can ... -
What is the nature of creativity: Understanding the role of executive and associative processes in creative thinking
(Georgia Institute of Technology, 2018-05-30)What is the Nature of Creativity: Understanding the Role of Executive and Associative Processes in Creative Thinking -
Understanding the training and transfer effects in N-back training
(Georgia Institute of Technology, 2018-05-22)Current research looking at the effect of working memory training on constructs such as fluid intelligence has generated mixed findings. Some researchers have found that training participants on working memory tasks leads ... -
Understanding automation handoff impacts on workload and trust when mitigated by reliability displays
(Georgia Institute of Technology, 2018-05-10)Current commercial vehicles are beginning to include automated features such as adaptive cruise control and automated lane keeping. This is a first step towards full vehicle automation which is predicted to be possible ... -
The social uses of self-defining memories at work
(Georgia Institute of Technology, 2018-05-01)A fundamental part of human experience is self-continuity, or the sense of me extended across time, yet these processes that give rise to this temporal extension have remained largely understudied in the work psychology ... -
An examination of emotional display rules using situational strength
(Georgia Institute of Technology, 2017-08-11)Although emotions are an integral part of our work experience, we cannot always show our genuine feelings while on the job. Many workplaces have either implicit or explicit requirements for emotional expression (known as ... -
Stochastic Approximation of the Multidimensional Generalized Graded Unfolding Model
(Georgia Institute of Technology, 2017-05-09)The multidimensional generalized graded unfolding model (MGGUM; Roberts & Shim, 2010) is a distance-based, unfolding multidimensional item response theory (MIRT) model for measuring person and item characteristics from ... -
The effects of an enhanced goal setting strategy on goal progress and well-being
(Georgia Institute of Technology, 2018-04-30)Although the benefits of difficult, specific goal setting on performance are well-documented (e.g., Locke & Latham, 1990), it remains unclear how anticipatory action planning may enhance these effects. The current study ... -
Everyday memory strategy use in older adults
(Georgia Institute of Technology, 2018-04-24)Existing everyday memory questionnaires and interview studies lack the depth of knowledge necessary to understand the ways in which older adults use their memories during their everyday lives. These assessments do not ... -
Separating contributions of prefrontal cortex subregions to age-related associative memory impairments
(Georgia Institute of Technology, 2018-03-28)The anterior prefrontal cortex (aPFC) is believed to play a critical role in integrating the outputs of lower-order processes, such as evaluations of item or inter-item properties. The high-order integration functions ... -
An investigation of pedagogical interventions within the productive failure methodology
(Georgia Institute of Technology, 2018-03-12)The assistance dilemma asks how learning environments should “balance information or assistance giving and withholding” (Koedinger & Aleven, 2007, p. 239). Minimal guidance (MG) methods posit that students learn best when ... -
Modifying distracting headphone audio to increase situation awareness
(Georgia Institute of Technology, 2018-01-03)Listener situation awareness (SA) was assessed in a dynamic auditory-only simulated roadway environment created with a multi-speaker setup. The ability of the listener to accurately report the presence, current location, ... -
The effect of experience on the use of multimodal displays in a multitasking interaction
(Georgia Institute of Technology, 2018-01-03)Theories and previous work suggest that performance while multitasking can benefit from the use of displays that employ multiple modalities. Studies often show benefits of these multimodal displays but not to the extent ... -
Gender differences in verbal, mathematical, and overall academic self-concept: a meta-analytic review
(Georgia Institute of Technology, 2017-12-07)The literature provides many examples suggesting that males have, on average, higher academic self-concept levels when compared to females, especially in mathematical domains. Three meta-analyses were conducted to examine ... -
Psychological and situational predictors of caffeine consumption in daily life
(Georgia Institute of Technology, 2017-11-22)The stimulant effects of caffeine have been widely studied. Research on caffeine has proceeded, similar to research on other drugs, with a focus on establishing the presence and magnitude of effects on physiological, ... -
Estimation of parameters in the generalized graded unfolding model using a genetic algorithm
(Georgia Institute of Technology, 2017-08-28)In the current study, a genetic algorithm was used in conjunction with the expectation-maximization algorithm to estimate parameters in a polytomous unfolding IRT model known as the generalized graded unfolding model (GGUM). ... -
Emotional and Cognitive Interest: How Creating Situational Interest Affects Learning with Multimedia
(Georgia Institute of Technology, 2016-12-09)There is disagreement in scientific literature over the educational benefits of generating situational interest (Rey, 2012). Situational interest refers to the positive affect and sustained attention triggered by features ... -
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 ...
