Distinctive movement patterns during embodied interaction by adults with HFA

Our latest analyses suggest that mutual gaze avoidance by people with autism could generalize to mutual touch avoidance during embodied interaction.

Autism Spectrum Disorder (ASD) can be understood as a social interaction disorder. This requires researchers to take a “second-person” stance and to use experimental setups based on bidirectional interactions. The present work offers a quantitative description of movement patterns exhibited during computer mediated real-time sensorimotor interaction in 10 dyads of adult participants, each consisting of one control individual (CTRL) and one individual with high functioning autism (HFA). We applied time-series analyses to their movements and found two main results. First, multi-scale coordination between participants was present. Second, despite this dyadic alignment and our previous finding that individuals with HFA can be equally sensitive to the other’s presence, individuals’ movements differed in style: in contrast to CTRLs, HFA participants appeared less inclined to sustain mutual interaction and instead explored the virtual environment more generally. This finding is consistent with social motivation deficit accounts of ASD, as well as with hypersensitivity-motivated avoidance of overstimulation. Our research demonstrates the utility of time series analyses for the second-person stance and complements previous work focused on non-dynamical and performance-based variables.

Talk on the cognitive science of cave art

I have been invited by the social anthropologists of the National School of Anthropology and History of the North of Mexico to visit them in Chihuahua.

I am excited by this opportunity to discuss the enactive approach to social interaction and to see how it can be put into a mutually informing relationship with anthropology.

Invited talk at the 3rd Joint UAE Symposium on Social Robotics

The 3rd Joint UAE Symposium on Social Robotics will be hosted by the United Arab Emirates University and New York University Abu Dhabi during 4-7 February.

The title and abstract of my invited talk are as follows:

Searching for the conditions of genuine intersubjectivity: From robotics to HCI

Tom Froese

Many our most valued experiences are experiences that we share with others. Yet the basis for this sense of we-ness remains mysterious. Could it really be possible that two people share one and the same experience? How so? I will argue that enactivists are starting to identify the conditions of this kind of genuine intersubjectivity. To be fair, theory of mind approaches to social cognition have also come a long way from folk psychological theorizing by paying more attention to neuroscientific evidence and phenomenological insights. This has led to hybrid accounts that incorporate automatic processing and allow an instrumental role for perception and interaction. However, two foundational assumptions remain unquestioned.

First, the cognitive unconscious: explanations assume there is a privileged domain of sub-personal mechanisms that operate in terms of representational personal-level concepts (belief, desire, inference, pretense, etc.), albeit unconsciously. Second, methodological individualism: such explanations of social capacities are limited to mechanisms contained within the individual.

The enactive approach has broken free from these representationalist-internalist conceptual constraints by directly integrating personal-level phenomenology with multi-scale dynamics occurring within and between subjects. Complex systems analyses of social robotics and agent-based models have demonstrated that there is nothing mysterious about the possibility of cognitive activity being distributed in a multi-agent system. Experimental investigations of real-time embodied social interaction mediated by human-computer interfaces demonstrate that co-regulation of interaction dynamics makes a difference to experience. This formal and empirical research on social interaction supports the possibility of genuine intersubjectivity: we can directly participate in the unfolding of each other’s experience.

Keynote at “The sensorimotor foundations of social cognition”

I have been invited as a keynote speaker to an autumn school on “The sensorimotor foundations of social cognition” organized by the Horizon 2020 project Socializing sensorimotor contingencies (socSMCs).

The event will take place in Boltenhagen by the Baltic Sea, Germany, October 11-17, 2015. My title and abstract are as follows:

Enactive and phenomenological approaches to social cognition

Tom Froese

One of the most central and also controversial claims of the enactive approach is that embodied social interaction is constitutive of social cognition. Evolutionary robotics modeling and dynamical systems theory demonstrate that at least in principle there is nothing mysterious about this claim. But can it also be verified experimentally? The most promising results so far are based on the “perceptual crossing” paradigm, in which pairs of participants interact haptically in real-time via a minimalist human-computer interface. They try to locate each other in the virtual space while avoiding distractor objects. It has repeatedly been shown that individuals’ actions become interactively self-organized in a way that collectively enhances task success. However, until recently there was no evidence that this sensorimotor self-organization was also experienced from the point of view of the participants, thereby calling into question whether it constitutively affected their social cognition. I will present the latest studies in which an accompanying phenomenology of intersubjectivity was clearly reported and quantified, thereby enabling us to identify the specific pattern of sensorimotor coupling underlying the emergence of a consciously shared moment of experience. This is some of the first evidence supporting the concept of a genuine and irreducible second-person perspective that is mutually enacted via joint actions. Intriguingly, the process of its emergence shares similarities with the first stages that are hypothesized to occur during the development of social awareness in pre-verbal infants.
