The Psychology of Nature

Published
By

Psychological research is advancing our understanding of how time in nature can improve our mental health and sharpen our cognition. From a stroll through a city park to a day spent hiking in the wilderness, exposure to nature has been linked to a host of benefits, including improved attention, lower stress, better mood, improved immune system, reduced risk of psychiatric disorders and even upticks in empathy and cooperation. [Source: https://www.apa.org/monitor/2020/04/nurtured-nature]

The Department of Cognitive and Learning Sciences has blended these wellness findings with the area’s abundance of outdoor activities and endless beauty into its new course – Nature Psychology. The course was developed by Dr. Samantha Smith, CLS assistant professor, with noteworthy contributions from several other faculty at MTU.The new course centers experiential learning and takes an innovative and interdisciplinary approach to helping students explore how our mental experience is connected to the natural environment. 

The course also featured a significant service learning component. In collaboration with Jill Fisher, program manager at the Keweenaw Land Trust (KLT), the students designed a pamphlet explaining many ways that spending time in nature is good for mental health, physical health, and cognitive performance. The pamphlet will be placed at various KLT trailheads and around the local community. The class also created a family-oriented activity with the aim of getting more people exploring the great outdoors, and the KLT-protected lands in particular.

This year’s course culminated with a weekend nature retreat in the Porcupine Mountains Wilderness State Park, allowing students to directly experience and reflect on concepts they discussed throughout the semester. The retreat, facilitated by Dr. Smith and Dr. Erika Vye, included hiking, outdoor cooking, nature-themed discussions and crafts, and time for interpersonal connection and reflection.

Complementary Research and Curriculum Development 

In addition to learning about traditional psychology themes, like the impact of time in nature on cognitive performance and mental health, the new course introduced students to a variety of other perspectives on the human-nature connection. Brigitte Morin (BioSci) illuminated the human body’s physiological response to spending mindful time in the natural world, and Dr. Mark Rhodes (SS) led students on an exploration of human geography, political ecology, and what the word “nature” really means. Dr. Chelsea Schelly (SS) engaged students in an exciting examination of environmentally responsible behaviors, and our interdependent relationship with the biophysical world from a sociological lens. Lisa Gordillo (VPA) spoke to some of her own and others’ work at the intersection of art and ecology to facilitate community engagement and conversations about environmental justice and human rights. Dr. Erika Vye (GLRC) introduced students to the importance of varied personal values for geologic features, the wide-ranging connections people have with landscape, and the value of geoheritage as a geoscience communication tool affording place-based learning experiences that nurture our sense of place. Dr. R.J. Laverne (CFRES) shared his expertise on urban forestry, and the consequences of becoming too disconnected from the natural world that we evolved to thrive in.

The takeaways to keep for life

Throughout the course, students gained a greater understanding of:

  • how nature impacts human psychology and physiology,
  • how an understanding of psychology and the human-nature connection can be used to promote positive social and environmental outcomes,
  • how to engage in and promote environmental stewardship efforts and become more environmentally responsible citizens of the Earth.

There’s More

The Nature Psychology course is not the only experiential learning opportunity provided by the CLS department. Course offerings also include Environmental Psychology, where students go outside the classroom to observe psychological principles and practices at play in various real-world settings. For example, during the course, students conduct a walkability survey of Houghton, and conduct a scavenger hunt at the A. E. Seaman Mineral Museum to explore the design of educational environments.

In the fall semester, during the Upper Peninsula’s famous “color season”, the department also organizes a “Psych Hike” – a group hike on one of the area’s beautiful trails. This is a great way to calm the mind, move the body, and enjoy time together in nature.

Shruti Amre receives “Best Poster” in first Computing[MTU] Showcase

Published
By

Michigan Tech’s College of Computing and the Institute of Computing and Cybersystems (ICC) co-hosted the first Computing[MTU] Showcase on April 4-6, 2022. Organizers say the showcase was intended to be a connection-maker on many levels, including undergraduate and graduate students presenting their most exciting innovations and current research.

The Department of Cognitive and Learning Sciences (CLS) was proud to have nine of the 40 entries in the Showcase’s research poster competition come from CLS students. With “Best Poster” going to Shruti Amre, ACSHF PhD student, for “Keep your hands on the wheel: the effect of driver engagement strategy on change detection, mind wandering, and gaze behavior”. Shruti is advised by Dr. Kelly Steelman.

Amre’s winning research poster

A few details on the research

Advanced driver-assist systems (ADAS) have revolutionized traditional driving by enabling drivers to relinquish operational control of the vehicle to automation for part of the total drive. These features only work under certain pre-defined conditions and require drivers to be attentive of their surroundings. While the features are engaged, there is an increased risk associated with drivers losing awareness of their environment. Popular manufacturers like Tesla requires drivers to have their hands-on-the-wheel while Cadillac’s ADAS requires drivers to keep their eyes-on-the road. We utilized a low-fidelity simulation and eye tracking to examine the effects of hands-on-the wheel and eyes-on-the road driver engagement strategies on change detection, mind wandering, and gaze behavior in a semi-autonomous driving task.

The showcase also hosted more than 20 speakers, including counterterrorism, health informatics, machine learning and security experts from companies and institutions ranging from Adobe, Amazon and Microsoft to the National Counterterrorism Center, the National Science Foundation and the U.S. Department of Defense.

Top Six Things to Consider when Choosing a University

Top Six Things to Consider when Choosing a University

By Beth Williams, Director of Admissions, Michigan Technological University, April 2, 2022

From Michigan Tech News. Read the original article.

The move from high school to college is a really big deal — but it doesn’t have to be overwhelming. Knowing the basics will help you get ready. To make the process of finding the right school a little less stressful, here are six key things to consider in your search.

1.) Outcomes

An education must be a smart investment in your future — and one that pays you back. Look beyond cost and consider the outcomes. Student loans are manageable (and often less costly per month than mandatory state tax withholding) when you have an outstanding resume to build on and lock in a high starting salary.

Gather data and compare placement rates within six months of graduation, median early career pay and return on investment. Ask about on-campus career fairs and the companies that visit campus to recruit students — for full-time jobs as well as co-ops and internships. How you’re able to distinguish yourself during college often adds to your success after graduation.

“Gerdau views the students of MTU as having a level of dedication and fortitude that isn’t easily found. Combine those values with the approach that MTU takes with its hands-on labs, highly educated professors, diversity initiatives and abundant leadership opportunities through project work and student organizations? Those are the reasons Gerdau is one of hundreds of employers that make the trek to the UP every year.” – Julie Soderberg, Gerdau

Amazon, IKEA, General Motors, Kimberly Clark, Los Alamos National Laboratory and more than 200 other companies and organizations make Michigan Tech a recruiting destination for our spring Career Fair. They know the talent tomorrow needs can be found at Michigan’s flagship technological university.

See how Michigan Tech pays you back.

2.) Class Size

A university’s average class size is important. Too big and you are just a number. Too small and you may not have access to the opportunities you’ll need to get ahead. Find a close-knit campus where you can learn — a place that provides opportunities to stand out on campus, so your education lets you stand out in the workplace.

You’ll have some larger lectures at Tech, but the average class size is 25 and our student-to-faculty ratio is 13 to 1. You’ll know professors and they’ll know you by name. Ask questions and engage in discussions. Get more out of your classroom experience.

3.) Support

It’s a fact. College is hard. To be successful, it’s critical that you maintain your health and overall well-being as you navigate your college experience. It’s okay to ask for help — from academic support to mental health and disability services. Be sure to review the resources and programming available on campus (or while working or taking classes remotely) to help you be well and thrive physically, mentally and academically.

Support resources to consider:

4.) Safety

On-campus safety and policy are major factors when considering a school — and so is the safety of the surrounding area. The greater community is directly connected to a university. What kinds of safety resources does a school have in place? Knowing the school’s policies and procedures concerning student safety can be useful in deciding whether or not it is the best fit.

Michigan Tech is proud be ranked as the safest public university in Michigan by Niche.com.

5.) Location

Location plays a major role in your college experience and it’s important to consider a school’s city, town and community. Do you want to see city lights or the northern lights? The way the community interacts with the college — and its students — is also important. Finally, consider the location’s opportunities to expand your interests and explore new activities and hobbies.

“The campus is located on Michigan’s most beautiful playground — the Upper Peninsula — and borders the Keweenaw Waterway, which connects to Lake Superior. Huskies spend a lot of time outside exploring, skiing, swimming, hiking, biking and even dogsledding.” – Chrissy Grotzke, Associate Director of Admissions

6.) Fit

How you feel at a school is perhaps the most important factor in your decision. The excitement of game day fades, so make sure your day-to-day experience is truly rich and rewarding.

Make time for a campus tour so you can walk around the campus. Watch how students interact with each other and consider if the atmosphere seems more collaborative or competitive. Schedule a time to talk with a professor or academic advisor for your intended major. Ask students what they like — and don’t like — about their school. Look for student organizations and activities you might like to join. Find a place where you feel a sense of belonging — where you’ll be an integral part of the community and can explore and grow with others who will support you.

“Michigan Tech is known for providing students with access to the support, care and resources they need to be successful. We’re here to support students and ensure they stay on track to graduate. That’s what we do — and we’re good at it. We work with faculty, academic advisors, academic department chairs, MTU college deans and other colleagues on campus to assist and support students through degree completion.” – Wallace Southerland III, Dean of Students

Most importantly, look for things that matter to you most and trust your gut. If it feels right, you’ll be that much happier at your new college home.

Michigan Technological University is a public research university founded in 1885 in Houghton, Michigan, and is home to more than 7,000 students from 55 countries around the world. Consistently ranked among the best universities in the country for return on investment, the University offers more than 125 undergraduate and graduate degree programs in science and technology, engineering, computing, forestry, business and economics, health professions, humanities, mathematics, social sciences, and the arts. The rural campus is situated just miles from Lake Superior in Michigan’s Upper Peninsula, offering year-round opportunities for outdoor adventure.

BASIC Computer Tutoring Resumes at Portage Lake District Library

Published
By

From WLUC-TV6. Published March 26, 2022.

HOUGHTON, Mich. (WLUC) – Since 2018, Michigan Tech University senior Mitchell Eckstrand has come to the Portage Lake District Library to help people in Houghton with computers. It is something he has enjoyed doing almost every weekend.

“If I can do my part to help other people feel more comfortable with their devices or other tasks that they’re doing on their computer, {then} it’s rewarding for me,” said Eckstrand.

These tutoring sessions are part of BASIC, which stands for Building Adult Skills In Computing. For at least 11 years, MTU professors and students have helped community members understand technology.

MTU faculty members Charles Wallace (CS/ICC-HCC, CompEd) and Kelly Steelman (CLS/ICC-HCC) direct the volunteer program.

“Sometimes, it’s questions they don’t know about,” said Chuck Wallace, an Associate Professor of Computer Science. “Sometimes, it’s problems with existing technology. But, we take them on one-on-one and work together with them.”

Saturday, marked the first in-person session in two years.

Besides regular computers, people get help with their tablets, phones, and even Chromebooks.

“Having some Chromebooks here for people who don’t have those is a really great way for people to be able to try out some more portable technology,” said Kelly Steelman, an Associate Professor of Human Factors and Psychology. “So, they might consider whether they want to get something like that for themselves.”

The program also helps those who are anxious about asking technological questions.

“As the pace of technology progresses,” Steelman explained, “it’s more of a common discussion that everybody needs help and will need help at some point.”

Eckstrand says those he and his peers help are not the only ones who learn something new.

“A lot of times, I’ll get questions that I don’t know the answer to, and then we’ll work together to figure out the problem,” he stated. “I learn a lot of things, too that I probably would have never known had I not been involved in this program.”

The BASIC sessions will continue helping others gain technological knowledge until the end of April, before starting again in September. They are open to anyone in the community, and no sign-ups are necessary. The free sessions are on Saturdays from 11:00 a.m. to 1:00 p.m. at the Portage Lake District Library’s Community Room.

Assessing Cognitive Empathy Elements within the Context of Diagnostic AI Chatbots

Empathy is an important element for any social relationship and it is also very important in patient-physician communication for ensuring the quality of care. There are many aspects and dimensions of empathy applicable in such communication. As Artificial Intelligence is being heavily deployed in healthcare, it is critical that there is a shared understanding between patients and the AI systems if patients are directly interacting with those systems. But many of the emotional aspects of empathy may not be achievable by AI systems at present and cognitive empathy is the one that can genuinely be implemented through artificial intelligence in healthcare. We need a better understanding of the elements of cognitive empathy and how these elements can be utilized effectively. In this research, the goal was to investigate whether empathy elements actually make a difference to improve user perception of AI empathy. We developed a scale “AI Cognitive Empathy Scale (AICES)” for that purpose and conducted a study where the experimental condition had both emotional and cognitive empathy elements together. The AICES scale demonstrated reasonable consistency, reliability, and validity, and overall, empathy elements improve the perceived empathy concern within diagnostic AI chatbots.

Easy Does It: Ease of Generating Alternative Explanations As A Mediator Of Counterfactual Reasoning In Ambiguous Social Judgments

According to sensemaking theory (Klein et al., 2007), people must first question their theory of a situation before they can shift their perspective. Questioning one’s perspective may be critical in many situations, such as taking action against climate change, improving diversity and equity at work, or promoting vaccine adoption. However, research on how people question their theories is limited. Using counterfactual theory (Roese & Olson, 1995), we examined several factors and strategies affecting this part of the sensemaking process. Eighty participants generated explanations and predicted outcomes in five ambiguous social situations. Likelihood of an alternative outcome was the measure for questioning one’s frame. Two models of the data were created. Using path analysis, we compared fit between a base model (i.e., ease, malleable factors, and missing information) and a model based on counterfactual generation theory with ease as a mediator. Results indicated that the counterfactual theory model fit was better, indicating that ease of generation may be a critical mediator in the sensemaking process. This work contributes to research focused on understanding of the mechanisms of perspective shifts to support applications for system design and training, such as programs to reduce implicit bias.

Examining Explicit Rule Learning in Cognitive Tutorials: Training learners to predict machine classification

Artificial Intelligence (AI)/Machine Learning (ML) systems are becoming more commonplace and relied upon in our daily lives. Decisions made by AI/ML systems guide our lives. For example, these systems might decide whether we get a loan, and the full-self driving car we’re sharing the road with even makes decisions. However, we may not be able to predict, or even know whether, or when these systems might make a mistake. Many Explainable AI (XAI) approaches have developed algorithms to give users a glimpse of the logic a system uses to come up with its output. However, increasing the transparency alone may not help users to predict the system’s decisions even though users are aware of the underlying mechanisms. One possible approach is Cognitive Tutorials for AI (CTAI; Mueller et al., 2021), which is an experiential method used to teach conditions under which the AI/ML system will succeed or fail. One specific CTAI technique involved teaching simple rules that could be used to predict performance; this was referred to as Rule Learning. This technique aims to identify rules that can help the user learn when the AI/ML system succeeds, the system’s boundary conditions, and what types of differences change the output of the AI system. To evaluate this method, I will report on a series of experiments in which we compared different rule learning approaches to find the most effective way to train users on these systems. Using the MNIST data set, this includes showing positive and negative examples in comparison to providing explicit descriptions of rules that can be used to predict the system’s output. Results suggest that although examples help people learn the rules, tutorials that provided explicit rule learning and provided direct example-based practice with feedback led people to best predict correct and incorrect classifications of an AI/ML system.

Connected Crossings: Examining Human Factors in a Field Study

Poor driver decision-making continues to be a challenge at Highway-Rail Grade Crossings (HRGC). One way to improve safety has been to introduce a new, in-vehicle warning system that communicates with the external HRGC warning systems. The system gives drivers different rail-crossing-related warnings (e.g., approaching crossing, train presence) depending on the vehicle location. In a rare field study, 15 experienced drivers drove a connected vehicle (Chevy Volt) and used the warning system on a 12-mile loop, then completed a semi-structured interview and usability survey. Results from the post-drive survey and interview are reported and provide a template for future usability assessments for field studies involving new technologies.

Don’t throw a tempo tantrum: the effects of varying music tempo on vigilance performance and effective state

Vigilance tasks, or sustained attention tasks, involve an operator monitoring an environment for infrequent and random critical signals buried among more frequent neutral signals for an extended period of time. In addition to an observable decline in task engagement, task performance, and arousal over time, these tasks are also related to an increased subjective workload. Previously, music has been shown to have a positive impact on operator engagement and reaction times during sustained attention, however the differences between fast and slow tempo music on vigilance performance and subjective mood measures have not been studied. The present study (N=50) examined the effects of music played at different tempos on a selection of performance metrics and subjective measures of mood, engagement, and workload. Results indicated that varying the tempo of music did not have an effect on the decline in the correct detection of critical signals. There also was not a significant impact on measures of arousal and stress, but the fast tempo condition had a slightly positive impact on worry and engagement from pre to post task subjective measures.

Human Factors in Healthcare Keynote: Dr. Rupa Valdez presents “Creating Systems That Promote Equity: A Journey Across Disciplines”

Published
By

Please join us Friday (Mar 25) in ATDC conference room 101 (and via Zoom); talk from 3:30-4:30, with interactive discussion to follow from 4:30-5:00.

Dr. Rupa Valdez is an associate professor at the University of Virginia with joint appointments in the School of Medicine and the School of Engineering and Applied Sciences. She is also a core faculty member of Global Studies and the Disability Studies Initiative. Dr. Valdez merges the disciplines of human factors engineering, health informatics, and cultural anthropology to understand and support the ways in which people manage health at home and in the community.

We encourage faculty and graduate students with any overlap in research, interest in collaboration, or just interest in learning more about Dr. Valdez’s work/journey/activism to join us!

This event is co-sponsored by CLS, KIP, and CSA, and is sponsored in part by the Michigan Tech Visiting Professor Program, which is funded by a grant to the Office of the Provost from the State of Michigan’s King-Chavez-Parks Initiative. Michigan Technological University is an Equal Opportunity Educational Institution/Equal Opportunity Employer that provides equal opportunity for all, including protected veterans and individuals with disabilities.

Abstract:
Catalyzed by the pandemic and by the killings of George Floyd, Breonna Taylor, and many
others, there is rapidly growing interest in determining how we can create sociotechnical
systems that promote equity rather than perpetuate disparity and injustice. In this talk, I share
and critically reflect on my journey toward this goal over the last decade. I begin with earlier
efforts to merge approaches from cultural anthropology and engineering to inform the design
of patient-facing health information technologies. I end with more recent community-based
participatory research and policy-based efforts to reimagine public health education, accessible
healthcare, and the role of community in shaping the research process.  My engagement with
historically marginalized communities has pushed my efforts from a primary focus on creating
technologies aligned with the contexts in which such communities are embedded to a broader
focus on working with communities to shift these contexts. In concluding remarks, I reflect on
how encouraging such work requires, at minimum, embracing a broader conceptualization of
engineering and, more ambitiously, work that may be considered a-disciplinary.

The Applied Cognitive Science and Human Factors (ACSHF) Forum will be held from 2-3 p.m. Monday (Jan. 24) virtually via Zoom.

There will be two speakers: Pomm Khaewratana and Alex Watral, both ACSHF graduate students.

Title: Learning with word game: Effects of crossword and elaboration on learning scientific vocabulary
Abstract: Crosswords have been used in a variety of science classrooms as a supplementary tool to help students learn technical vocabulary and to improve scientific thinking. However, the majority of crossword studies showed positive findings only for the former and almost none for the latter. We currently lack evidence for the usefulness of crossword in learning anything beyond the vocabulary and their definition or associated context provided as crossword hints. In this presentation, I will describe a continuation of the series of my experiments that evaluate the effect of crossword with an add-on elaboration task. The task supposedly enhances learning and retention of learned vocabulary by having learners generate sentences from technical words that depict an application-based use of the words. Fifty undergraduate students were recruited as participants in the aforementioned within-subject-design experiment. Results indicated significant improvement on memory level but not on the higher level of application.

Alex Watral:
Title: Online Assessment of Motor Learning in Younger and Older Adults
Abstract: Motor learning is a specific type of learning that occurs through repetition of a movement following the law of practice wherein rapid improvements in performance occur initially, followed by more gradual improvements as practice continues. In this sense, we can think of motor skill learning as unfolding in two phases that may rely on different cognitive mechanisms. Evidence has shown that motor learning abilities change with healthy aging such that older adults are slower to learn novel motor tasks initially while ultimately they are still able to learn to the same degree as young adults. One of the gold-standard approaches to studying motor learning is called the visuomotor rotation (VMR) paradigm. Motor learning tasks like the VMR paradigm are typically implemented in our lab using a robotic device called a Kinarm. As our understanding of motor learning evolves, we need to focus on options for testing that are more accessible than laboratory limited approaches. We have created a web-based application to assess visuomotor adaptation in a remote setting. No application downloads are required on the part of the participant. The only requirement is for them to have a computer (laptop or desktop) and an internet connection. This makes the application far more accessible than current laboratory and portable platforms. The overarching goal of this project is to validate the web-based application in younger adults as well as healthy older adults. We are also interested in verifying that previously identified correlations between the early and late stages of motor learning and implicit memory, spatial working memory, and visual-spatial abilities can be observed with this online app. Healthy younger adults (n=21) and healthy older adults (n=17) participated in this study. Each participant met with a researcher via Zoom and shared their screen while performing the VMR task and cognitive battery so that the researcher could troubleshoot as needed. Preliminary results suggest that the online application produced results similar to the laboratory task. Further analyses will be conducted to determine if there were significant differences between the two collection methods (app vs laboratory) and to see how cognitive constructs correlate with performance on the VMR app.
