Effects of Sleep Deprivation on Performance during a Change Signal Task with Adaptive Dynamics Open

Kimberly A. Honn, Megan B. Morris, Melinda L. Jackson, Hans P. A. Van Dongen, Glenn Gunzelmann · 2023

Augmented cognition, which refers to real-time modifications to a human–system interface to improve performance and includes dynamic task environments with automated adaptations, can serve to protect against performance impairment under ch…

Enhancing learning and retention through the distribution of practice repetitions across multiple sessions Open

Matthew M. Walsh, Michael Krusmark, Tiffany Jastrembski, Devon Hansen, Kimberly A. Honn , et al. · 2022

Enhancing Learning and Retention through the Distribution of Practice Repetitions across Multiple Sessions Open

Matthew M. Walsh, Michael Krusmark, Tiffany Jastrembski, Devon Hansen, Kimberly A. Honn , et al. · 2022

The acquisition and retention of knowledge is affected by a multitude of factors including amount of practice, elapsed time since practice occurred, and the temporal distribution of practice. The third factor, temporal distribution of prac…

Fundamental tools for developing likelihood functions within ACT-R Open

Developing memory-based models of ACT-R within a statistical framework Open

Christopher R. Fisher, Joseph W. Houpt, Glenn Gunzelmann · 2020

New insights into the cognitive effects of sleep deprivation by decomposition of a cognitive throughput task Open

Kimberly A. Honn, Tim Halverson, Melinda L. Jackson, Michael Krusmark, Venkata P. Chavali , et al. · 2020

Study Objectives A cognitive throughput task known as the Digit Symbol Substitution Test (DSST) (or Symbol Digit Modalities Test) has been used as an assay of general cognitive slowing during sleep deprivation. Here, the effects of total s…

Strategic Differences in the Coordination of Different Views of Space Open

Glenn Gunzelmann, John R. Anderson · 2019

Participants were trained to use one of two different strategies in an orientation task, which were based on verbal reports from participants in another experiment. The data provide support for the conclusion that participants in the two t…

Mechanisms underlying the spacing effect in learning: A comparison of three computational models. Open

Matthew M. Walsh, Kevin A. Gluck, Glenn Gunzelmann, Tiffany S. Jastrzembski, Michael Krusmark , et al. · 2018

The spacing effect is one of the most widely replicated results in experimental psychology: Separating practice repetitions by a delay slows learning but enhances retention. The current study tested the suitability of the underlying, expla…

Examining the Role of Task Requirements in the Magnitude of the Vigilance Decrement Open

Daniel Gartenberg, Glenn Gunzelmann, Shiva Hassanzadeh‐Behbahani, J. Gregory Trafton · 2018

The vigilance decrement in sustained attention tasks is a prevalent example of cognitive fatigue in the literature. A critical challenge for current theories is to account for differences in the magnitude of the vigilance decrement across …

Relationship of Event-Related Potentials to the Vigilance Decrement Open

Ashley Haubert, Matt Walsh, Rachel Boyd, Megan B. Morris, Megan Wiedbusch , et al. · 2018

Cognitive fatigue emerges in wide-ranging tasks and domains, but traditional vigilance tasks provide a well-studied context in which to explore the mechanisms underlying it. Though a variety of experimental methodologies have been used to …

Evaluating the Theoretic Adequacy and Applied Potential of Computational Models of the Spacing Effect Open

Matthew M. Walsh, Kevin A. Gluck, Glenn Gunzelmann, Tiffany S. Jastrzembski, Michael Krusmark · 2018

The spacing effect is among the most widely replicated empirical phenomena in the learning sciences, and its relevance to education and training is readily apparent. Yet successful applications of spacing effect research to education and t…

Further Evidence That Sleep Deprivation Effects and the Vigilance Decrement Are Functionally Equivalent: Comment on Altmann (2018) Open

Glenn Gunzelmann, Bella Z. Veksler · 2018

Veksler and Gunzelmann (2018) argue that the vigilance decrement and the deleterious effects of sleep loss reflect functionally equivalent degradations in cognitive processing and performance. Our account is implemented in a cognitive arch…

Functional Equivalence of Sleep Loss and Time on Task Effects in Sustained Attention Open

Bella Z. Veksler, Glenn Gunzelmann · 2017

Research on sleep loss and vigilance both focus on declines in cognitive performance, but theoretical accounts have developed largely in parallel in these two areas. In addition, computational instantiations of theoretical accounts are rar…

Computational cognitive modeling of the temporal dynamics of fatigue from sleep loss Open

Matthew M. Walsh, Glenn Gunzelmann, Hans P. A. Van Dongen · 2017

Visual Working Memory Resources Are Best Characterized as Dynamic, Quantifiable Mnemonic Traces Open

Bella Z. Veksler, Rachel Boyd, Christopher W. Myers, Glenn Gunzelmann, Hansjörg Neth , et al. · 2017

Visual working memory (VWM) is a construct hypothesized to store a small amount of accurate perceptual information that can be brought to bear on a task. Much research concerns the construct's capacity and the precision of the information …
