Working Memory and Language Laboratory

We are interested in how children remember the words they hear or read, especially when they have other things distracting them. Our research tries to find what kinds of distractions are too distracting, and why some children remember better than others.

  • ​​​​​​​​​​​​​​​​​Overview

    WELCOME TO THE WORKING MEMORY AND LANGUAGE LABORATORY!

    What is Working Memory?

    Working memory refers to the ability to remember information for short periods of time in order to solve a problem or accomplish a task.  Remembering a list of ingredients while navigating the grocery store, following the steps of a recipe, and converting fractions for a double-batch of cookies all require working memory.  Working memory isn't only useful for cooking. It's used whenever you have to figure out something new, and it supports long-term learning.

    Why is language important to working memory?

    Working memory is important for making sense of language.  We can only hear or read words one-at-a-time. Therefore, we must hold onto the words—and their order—while simultaneously creating meaning and thinking about our own response. Children with hearing loss must especially rely on working memory. Because the auditory signal they get is sometimes ambiguous, children with hearing loss often problem-solve to work out the meaning of what they hear.

    Current Projects:

    AUDITORY DISTRATION IN CHILDREN

    If we want to ignore parts of our visual world, we can easily just turn around or shut our eyes. Children with typical hearing cannot just "turn off" their hearing; therefore, the auditory world poses a constant opportunity for distraction. Although the presence of irrelevant sound impairs memory in children, we believe that it also provides a valuable opportunity to learn to control attention in the face of distraction. First, we want to understand how these attentional processes develop in typically-hearing children to support memory and learning. Then we will explore how attentional development is impacted by a period of hearing deprivation and the subsequent ability to "turn off" hearing aids and cochlear implants.

    THE DEVELOPMENT OF "SELF-TALK" AS A MEMORY STRATEGY

    It is common for adults to talk to themselves when they need to remember something. When an adult silently says the same word or phrase over and over in an attempt to commit it to memory, we call this rehearsal. Unfortunately, we know much less about how and when children rehearse. In this project, we measure how children's rehearsal changes as the memory task gets harder. We also want to know how children's use of rehearsal changes over time.

  • Team

    Angela AuBuchon, Ph.D., is the Director of the Working Memory and Language Laboratory.  Her doctoral training was conducted at the University of Missouri under the mentorship of Dr. Nelson Cowan, whose Embedded Processes Model of Working Memory serves as one of the most-often-cited alternatives to Alan Baddeley's Multicomponent Model. In 2012, she moved to Bloomington, Indiana where she received postdoctoral training from Dr. David B. Pisoni. Her postdoctoral work investigated the executive function of children and adolescents with cochlear implants. Prior to earning her Ph.D., Dr. AuBuchon worked as a behavioral interventionist with Missouri FirstSteps and the Judevine Center for Autism in St. Louis, Missouri. These experiences inspire her to apply her deep theoretical training to answer clinically relevant questions.

    Grace Meissner, B.A., is a research assistant in the Working Memory and Language Laboratory. She received her bachelor's degree in psychology from the University of Nebraska Omaha in 2015. She is currently working on her master's degree in Clinical Mental Health Counseling. Grace has had previous experience working with children and adults with developmental disabilities. She has worked as a direct support professional at the Autism Center of Nebraska and as a special education paraprofessional at Bellevue Public Schools.  

    Rebecca Wagner is a research assistant in the Working Memory and Language Laboratory. She is currently pursuing her B.S. in psychology with a concentration in cognitive psychology and a minor in biomechanics at the University of Nebraska at Omaha. Her passion for research has brought her to the Working Memory and Language Laboratory at Boy's Town National Research Hospital where she hopes to further her knowledge and skills in the field of research before pursuing her graduate studies in cognitive psychology.

    Allysia Holm, A.A., is a research assistant in the Working Memory and Language Laboratory. She received her Associates degree in psychology from the Chandler Gilbert Community College in 2017. She is currently working on her Bachelor’s degree in Psychology at the University of Nebraska at Omaha. Allysia has previous experience working with children and teenagers from all different backgrounds. Working with children has led her to work towards becoming a child psychologist to help the youth of today.

    When you arrive

    A research staff member will greet you at the door and escort you to the lab. The staff member will explain the study and answer any questions you may have. You and your child will be given a form to formally consent to participate in the study.

    Please note that a parent or legal guardian must accompany child participants to their research appointment.

    During the visit

    Participants will be given a hearing and vision screening. Some participants may receive additional language and neurocognitive testing. The length of the visit varies, but tend to be 1-2 hours. Participants will be given frequent breaks.

    During the study, participants will be asked to remember numbers, words, or pictures. Your child may be asked to listen to sounds through headphones. We are also incorporating novel measures, such as surface electromyography and respiration rate, as physiological indicators of silent self-talk. Some participants may wear stickers on their neck and face that let us measure muscle movement.

    We have a waiting room with toys where parents/guardians may supervise and entertain any other young guests (e.g. your child's siblings) who may need to accompany you to the appointment.

    After the visit

    When we are done, participants will be compensated for their time. Our child participants will also get to pick out a small prize. Some participants will be offered the opportunity to return for a follow-up visit.

    Thank you for participating in research at Boys Town National Research Hospital!
