Usually, memory\u2019s a helpful thing to have when you\u2019re working on a project. It\u2019s a lot easier to find your keys if you remember where you put them down, for example. But your memories might not always be so beneficial. Professor Deborah Hannula <\/a>is conducting research in the relatively unexplored field of memory\u2019s effects on attention, and her work has netted her the first National Science Foundation CAREER Award to ever be earned by a member of the UWM Psychology Department. Hannula’s is a five-year grant that was awarded in June. \u201cNSF CAREER grants are one of the nation\u2019s premier awards for young researchers who are on their way to becoming the future leaders in their fields. Our Psychology Department\u2019s rapidly rising national reputation is due in large part to the cutting-edge research conducted by Deborah Hannula and others,\u201d said Rodney Swain, Dean of the College of Letters and Science at UWM. Hannula\u2019s research seeks to answer questions about whether people\u2019s attention can be co-opted from the task at hand if there is a meaningful and remembered object within the environment. The answers she finds could impact the field of mental health.<\/p>\n

\u201cThe research may have implications for things like Post Traumatic Stress Disorder or certain types of psychiatric conditions,\u201d Hannula said. \u201cImagine that you’ve had a negative experience and that a neutral object was present at the time. This neutral object happens to be something that is present in the environment in lots of situations. … It is reasonable to ask, will the object suddenly capture your attention in a way that keeps you from completing on-going tasks effectively?\u201d<\/p>\n

To answer that question, Hannula will be conducting experiments that measure the eye movements and brain function of her participants. Participants will study a series of pictures to commit them to memory for a test at the end of the experiment. Before the test, they\u2019ll engage in an attention task: Participants will be told to look at the middle of a screen
\nat a fixed point and respond to a target stimulus – in this case, they\u2019ll try to fi nd an orange spot that will appear on the screen – as quickly as possible. The pictures they studied may be appear as well during this task, but they are irrelevant and unrelated to the current goals or objectives.<\/p>\n

\u201cUnder these circumstances, we can address questions about the potential for remembered content to capture attention, and if this occurs, we can evaluate how long it takes before attention can be effectively disengaged and reallocated in a manner consistent with current objectives,\u201d Hannula said. \u201cThe work has potential real-world implications because it\u2019s possible that memory-based capture is slowing us down or making us less effective in a variety of situations, particularly in cases of neurological or psychiatric disorder. \u2026 In addition to addressing these basic questions, we will also attempt to identify the neural mechanisms that contribute to capture and subsequent disengagement of attention from capturing content.\u201d<\/p>\n

She measures the \u201cmemory-based capture\u201d by tracking the participants\u2019 eye movements with infrared light. The light, projected from a camera, creates a corneal reflection off of the eye. The camera keeps track of the position of the reflection with respect to the eye\u2019s pupil and Hannula uses that data and a computer algorithm to determine where the participant was looking and for how long.<\/p>\n

In addition, Hannula will be using Functional Magnet Resonance Imaging, or fMRI, to measure brain activity during the performance of the task. The scans are expensive \u2013 about $1,000 per participant \u2013 so the CAREER grant will help defray the costs of the project. The fMRI shows which parts of the brain are active during the memory and attention task. \u201cWe\u2019ll be able to look at trials in which participants\u2019 eye movements were captured by an object versus trials in which that didn\u2019t happen, and then we can see, by comparing these two trial types, the brain regions that are more active when capture occurs \u2013 the identified regions must be contributing to that process,\u201d Hannula said. \u201cWe\u2019re going to be collecting the eye movement data during scanning. So we\u2019re combining those two techniques. That way, we\u2019ll be able to sort the trials not only on the basis of behavioral performance like response time, but also based on these eye movement measures of capture, which is unusual. Very few researchers combine fMRI and eye-tracking methods like this.\u201d<\/p>\n

Hannula\u2019s work doesn\u2019t stop with her experiments, however. The NSF CAREER grant includes an educational and community outreach component. Over the summer, Hannula hosted a three-day workshop for high school students in the Upward Bound math and science program at UWM to introduce them to the basics of attention, memory and neuroscience. In the fall of 2015, she will be teaching a freshmen seminar to discuss how cognitive neuroscience is portrayed in the media, especially in the context of computerized brain-training tools that have become increasingly popular. Hannula will also be forming a book club to encourage community members to read and think about the brain and memory.<\/p>\n","protected":false},"excerpt":{"rendered":"
