Previous works have shown that labeling of item pairs can be influenced by how close the two items are presented and whether or not the items are categorically-related to one another. However, these works have not investigated what effect the process of verbal labeling has on later memory of the items within the pairs. This work aims to address this gap at both the group and individual level.

False memories have been shown to increase with age, but interventions have been shown to mitigate the negative effects of age on memory. This project aimed to develop a new monitoring intervention and examine how practice with this strategy changes both behavioral and neural correlates of false memory production in older adults.

​

A fully remote project aimed at understanding the various ways adults use memory strategies and how they change based on stimuli and list length. This project expanded the historical definitions used to identify strategies by using ML clustering analyses to group co-dependent strategy reliance, which was then used to predict memory and task performance.

This project assessed children and adolescents on an implicit learning serial recall task where half of the task was reliant on language and the other was not. The goal of this project was to compare speed and recall accuracy between young cochlear implant users and typically developing children.

Typically developing children are tasked with remembering lists of digits in order. Depending on the child's age, and the list length received, different patterns of rehearsal are expected. These varying factors were expected to influence the recall accuracy of the children.

In this study, I aimed to understand the influence of background noise and age on adult recall accuracy and false memory production in an auditory DRM task. Young adults and older adults were anonymously recruited from the United States to participate.

An adaptation from previous work out of the Working Memory and Language Lab, this remote study presented lists of phonologically similar and dissimilar words. Participants were instructed to serially recall the lists and self-report their memory strategies using our strategy survey.

This was a longitudinal study conducted at the University of Nebraska at Omaha by Dr. Vivien Marmelat, Ryan Meidinger, Meghan Prusia, and colleagues. This study is observing prefrontal cortical data along with gait pattern analyses during single- and dual-task walking to gauge the role of attention as a predictor of falls in older adults with Parkinson's Disease.

This was a registered replication of Flavell, Beach, and Chinsky's 1966 publication which found that older children (age 10) produced more spontaneous verbalization behaviors compared to younger children (age 5) during a memory task. This report used multi-site data collection procedures to collect data from over 900 children. The replication found that, similar to the original study, older children were more likely to verbalize, improving their memory spans. Unlike the previous study, younger children used overt verbalization more often and those that did had significant increases in their recall ability.

This project used vocoding technology to degrade the acoustic representation of words. The representation of those words were then mapped onto phonetically matching, or mismatching words. Participants were trained on these mappings, then were asked to complete a serial recall task.

This project was a multi-site project between the Cortese Lab at the University of Nebraska at Omaha and researchers at Doane University. The project compared child and young adult recall and false memory production on an auditory DRM task. The within subjects design compared participant's list recall accuracy and false memory production when they were recalling the list by writing down their answers, or when they were recalling the list aloud to the present researcher.
