Social work doctoral student connects research to her community


June 11, 2018

Charlene Poola says her interest in social work started with her mother.

“I am Hopi-Tewa and Navajo. My mother would be sure that the elders in our community had transportation to get groceries or go to the Laundromat. She would take them to town to get a warm meal,” Poola said. “I saw her community mobilizing. I didn’t know it was social work, but thought — that’s what I want to do.” Charlene Poola Charlene Poola Download Full Image

Poola is now pursuing her PhD in social work at Arizona State University. She is also one year into a prestigious Council on Social Work Education Minority Fellowship Program for doctoral students.

The program supports students who are leading efforts to improve healthcare outcomes for diverse, underserved populations.

Connecting research and practice

Before coming to ASU, Poola spent 14 years working with tribes in New Mexico.

“I really liked working with tribal organizations to enhance their behavioral systems. I was working for the University of New Mexico to bring in partnerships. My goal was to make sure our work was engaged, using community-based participatory research principles,” she said.

Poola did a needs assessment with New Mexico Native American tribes. It took nearly eight months to identify behavioral health resources, types of therapy provided and support the tribal organizations wanted to see and their thoughts about evidence-based treatments.

“Back then evidence-based was a buzzword,” she said. “I compiled the feedback and was able to present the needs to UNM and the tribal organizations to develop resources.”

“I didn’t want to collect data just to collect data,” she said. “This is what the tribes need and we have a responsibility as a public institution to support those needs. I also didn’t want to do that without tribal involvement.”

The results of her assessment took off for eight years. She helped three tribes get SAMSA grants. They implemented clinical trainings statewide that fused traditional and western culture.

Poola would stay with UNM but moved to more of a hospital environment.

“I discovered that I didn’t really like it. I realized that I am a community-based person. I also realized that our work — American Indians — was not being represented in research so that’s when I decided to come back to school,” she said.

Bringing expertise back to the community

Poola examines how to help American Indians adapt evidence-based treatment to fit their communities. She is particularly interested in the process.

“When I graduated with my master’s degree, I was a clinical social worker. The first thing I wanted to do is find out what treatments are out there for American Indians. At that time — 2003 — there were none. So what are we doing in the field to make it work?”

Poola says she learned from the team who had years of experience.

“Now, I know what occurs, because I have 14 years of practice but I didn’t document how I did it. I just knew surface adaptations that needed to occur,” she said. “I knew we needed to start doing this. Our upcoming generation of clinicians needs to have a bag of tools to provide the best treatment possible.”

She’ll be working with tribes in New Mexico as part of her dissertation.

“Social work is about addressing social injustices, social equality. I feel like if we have more students of color addressing this, maybe there would be more equitable resources for all to access,” Poola said.

It crawls and flies: ASU student wins award to study time perception

Carter Daniels earns American Psychological Association research award


June 11, 2018

Time seems to stand still during a cross-country flight, but then it flies while you're reading a good book. Carter Daniels, a graduate student in the Department of Psychology at Arizona State University, thinks a lot about this paradox.

Daniels won an American Psychological Association (APA) Dissertation Research Award, with high distinction, for his work on time perception.

To apply for the award, students had to write a proposal, and Laurie Chassin, Regents’ Professor of psychology and director of graduate studies, selected which applications to send to the APA. Daniels was one of about 40 graduate students across the country, along with fellow graduate student Michael Sladek, who won the award

“The Department of Psychology was allowed to submit just two applications to the APA,” Chassin said. “And we received both!”

The award provides money for research costs, which will help Daniels complete experiments for his doctoral dissertation.

“My research shows that our perception of time is not as sensitive as scientists previously thought,” Daniels said. “I am bringing a new perspective to how we understand the passage of time.”

Theories that explain how we understand time assume that what motivates us is interconnected with our knowledge of time. After arriving at ASU, Daniels created mathematical models that contradicted this idea.

“I was finding the opposite with computational models,” Daniels said. “So we started thinking about how we could test this idea without a model.”

Sanabria and Daniels use mathematical models and carefully designed experiments to ask questions about how animals understand time. In the experiments, animals might have to press a lever for a food reward or they might have to listen for a sound before performing an action. Results from experiments like these can help scientists understand how humans think about time.

One of the experiments Daniels proposed for the award has the animals press a lever to receive a food reward, which arrives after a certain amount of time.

“The animals pause for about two-thirds of the waiting interval before pressing the lever for more food,” Daniels said. “How long they pause is an estimate of how close they think they are to receiving the food.”

Daniels and Sanabria thought up another simple way to test how animals understand time: they let the animals decide when to start the experiment. The researchers watch for the animal to perform a specific behavior at a certain time that lets the researchers know the animal is ready to begin. For example, the animal might poke his nose into a hole to indicate he is ready to start the experiment.

“We have asked animals to start engaging in a timing task whenever they want,” Sanabria said. “When we do this and change their motivational state, they still perform just as well.”

When the animals did not have control over when the experiment began, they did not track time as well. The animals’ ability to track time was also affected by their motivational state, or their mood. Daniels and Sanabria think this finding is likely true for humans too.

“Imagine a kid walks into class and the teacher gives a pop quiz. Their performance is based on their knowledge but also on the stress of the timing,” Daniels said. “Maybe if the kid were able to choose when to take the quiz, performance would improve.”

Daniels also suggested that his research might apply to how children with attention deficit hyperactivity disorder are accommodated.

“An answer might be to let them pace the world,” Daniels said. “Give them a little bit of control in situations like school.”

Daniels chose the ASU’s Department of Psychology for his doctorate because he wanted to work with Sanabria as a computational psychologist. He soon benefited from how the psychology department and university value collaboration and interdisciplinary research.

“Fed (Sanabria) facilitates my ideas,” Daniels said. “And I don’t know of many other places where I would have received both computational and experimental training.”
