Our Research

Interaction between history, social context, and action patterns

Most of our projects are centered around furthering our understanding on how agents’ histories (e.g. having been diagnosed with a disorder, meeting a participant in the laboratory setting versus completing studies with a friend, having gone through a global pandemic) affect the unfolding patterns of action and task performance in varying situations. 

Current Projects

How contextual constraints affect conversations

The lab is interested in exploring how conversations are affected by different contextual constraints. We are interested in better understanding these effects multi-modally, starting with interpersonal coordination, acoustic patterns and language dynamics. So far, we have one published project in this area with the following findings: Interpersonal coordination of body movement—or the similarity in patterning and timing of body movement between interaction partners over time—is a well-documented phenomenon in face-to-face (FTF) conversation. The present study will investigate the degree to which interpersonal coordination is impacted by the amount of visual information available and the type of interaction conversation partners are having. To do so within a naturalistic context, we take advantage of changes induced by the 2020 COVID-19 pandemic. The pandemic has changed communication, with mitigation efforts having forced nearly everyone to engage over videoconferencing (VC) platforms (which limit body visibility but not face visibility) or to meet FTF with public health constraints (which limit face visibility but not body visibility). We will ask 69 pairs of participants to communicate in one of three ways: (1) socially distanced FTF while wearing masks; (2) VC in a laboratory where each partner will see one another’s full torso; or (3) VC in a remote setting where each partner will see only one another’s face and shoulders. Each pair will hold three conversations: (a) affiliative, (b) argumentative, and (c) task-based. We will quantify interpersonal coordination by extracting overall amounts of movement from videos of the participants using well-validated computer vision methods and then calculating the relationship between the two participants’ movement using nonlinear time series analyses. In doing so, we will be able to identify the degree to which visual information and conversational context shape the emergence of interpersonal coordination within now-naturalistic modes of interaction.

How social factors affect our actions during interactions

We often observe individuals expertly coordinating their bodily movements with other individuals around them. Whether crossing a road with a group of individuals at a cross-walk, moving a table and chairs with friends or family, or shaking hands with a colleague, individuals frequently perform social behavioral coordination in a robust and flexible manner, with seemingly little or no effort. A central question in the study of joint action and social coordination concerns how the observed movements of other individuals and objects in the environment influence the production of one’s own actions. While several researchers have theorized that such phenomena are the result of the pre-motor cortex representing action execution and observation simultaneously and in a common code, known as the motor contagion account, I argue that the dynamic patterns of coordination that exist between produced and observed movements naturally arise from holistic interactions between the neural, biomechanical, and perceptual subsystems of the agents and the agents’ environment. My research has focused on the interpersonal coordination that arises between agents while performing different tasks. Due to the pandemic most of this work took place before my start at Colby and with small projects with students in my seminar with collaborative research course. This work, in general has demonstrated that coacting individuals can become temporarily organized to form acting systems, and that therefore we should study behaviors happening in social situations at the level of the coacting system, rather than the individuals separately. 
My first semester teaching at Colby I taught my Human Movement seminar plus collaborative research course and had one group of students who were interested in investigating how a person’s emotional state might affect interpersonal coordination. This was a well-designed project spear-headed by a hard-working group of students. We discovered a complex relationship between emotion, liking and interpersonal coordination. One of the students, Margaret Hall ’20, reached out to me once she had graduated and we decided the project was interesting enough to polish the paper and try to get it published. We were successful in getting it to publication. I like to highlight this particular study because it is the first time I am lucky enough to get a student motivated to see the whole process through and it was a very rewarding experience. 
The second project stemming from the seminar that I would like to highlight is one that was part of the fall of 2021. Students in this course are often interested in how athleticism or being part of a sport team affects coordination abilities and influences the level of interpersonal coordination they might be able to achieve. One group of students studied how interpersonal coordination was affected by whether participants were part of a varsity team sport, an individual sport, or no varsity membership at all. Interestingly, they found that participants who play in a team varsity sport showed significantly more interpersonal coordination while rocking chairs next to another team varsity player than individual varsity athletes and non-athletes. There was no significant difference in level of interpersonal coordination for individual varsity athletes and non-athletes. This was an interesting finding, since we expected that any athlete would show an enhanced level of interpersonal coordination. However, upon closer inspection, we realized that all the team varsity athlete pairs were comprised of team-mates, which is a big confound. This group of students – Eliza Dean ’22, Katharine Dougherty ’22, and Javon Williams ’23 – were so interested in the project that we are currently collecting more data to actually answer a more complex question. We have decided to dig deeper and try to untangle the athletic aspects from the social connections that might be forged by belonging to the same team or being close friends. We are still collecting data for this project with the hope of completing data collection by the end of spring semester 2024.

How Autism affects social interaction and cognition

Children with autism spectrum disorder (ASD) exhibit impairments in social interactions that last throughout their lives. These impairments can severely impede learning and overall social functioning at home and in school, as well as make successful treatment difficult. We study these impairments using a dynamical systems, ecological psychology perspective. 

We strive to improve diagnostic as well as treatment options that already exist to include quantitative, time-evolving behavioral data. Currently, I am focusing on gaining a deeper understanding of the patterns observed in social communication in children with and without autism by using deep machine learning techniques. These new mathematical tools have the potential to unveil those aspects that lead to uncomfortable social interactions with children with ASD. Eventually, the goal would be for us to collaborate with clinical psychologists on advancing and utilizing the new non-linear methods and computational skills I explore during their day-to-day diagnostic routines as well as designing intervention programs informed by the results of these projects.

Future Project: How a partnered dance intervention affects relationships 

This line of questioning started in the fall of 2020 when Annie Kloppenberg in the theater and dance department introduced me to Jessie Laurita-Spanglet, who was then a visiting assistant professor here at Colby. We met a few times and discovered that we had some overlapping interests and designed the study described below that we plan on embarking as soon as we have enough funding to pay participants. Hopefully, this will be as soon as the spring of 2024. 
While it has been theorized that partnered improvisational dance interventions, like IMPROVment®, would be highly beneficial for people due to the development of skills that foster flexibility in movement and thinking which would suit well to our unpredictable everyday life, there has been very little research studying these types of interventions in a dynamical way and no research focusing on the social aspect of the intervention. Importantly, the proposed study will directly look at how much partnered dance interventions in general affect and/or benefit patient care partners in different ways, including how we can measure interpersonal coordination between partners in a dynamic and objective way through the use of motion trackers. The insights gained from the proposed project could have the potential to change how we implement and study dance interventions in multiple populations in the future with a focus on the social and psychological benefits gained.
