We suggest that the two constituents of a second-person approach proposed by Schilbach et al. – emotional engagement and social interaction – are best seen as aspects of bodily or skilled intentionality. Skilled intentionality can be understood as adequate responsiveness to a field of relevant affordances (Rietveld, in press) enabled by embodied know-how or abilities. From phenomenology (e.g., Merleau-Ponty Reference Merleau-Ponty and Smith1945/2002) and ecological psychology (e.g., Gibson Reference Gibson1979; Reed Reference Reed1996) we learn that normally we engage skillfully with our environments (Ingold Reference Ingold2000/2011). This skillful engagement is a form of unreflective action that is “solicited” or “motivated” by the situation. It is characterized by responsiveness to “affordances” (Gibson Reference Gibson1979; Rietveld Reference Rietveld2008); to possibilities for action offered by the environment. Affordances are relations between aspects of the environment and abilities (Chemero Reference Chemero2003). Crucially, we are selectively responsive to one affordance rather than another: In the context of the particular situation and depending on the person's concerns, some affordances are more relevant than others. Social affordances are a subcategory of affordances, namely possibilities for social interaction offered by the environment. For example, a friend's sad face invites comforting behavior, a person waiting for a coffee machine can afford a conversation, and an extended hand affords a handshake. The field of relevant affordances integrates social affordances and other affordances such as object affordances, epistemic affordances, place affordances, and even possibilities for reflection.

Although social interactions are extremely important for understanding both our everyday life and possible disorders of it, it is important to take into account that they take place within a broader context: Any relevant possibility for social interaction is embedded in a field of other soliciting possibilities for action. While engaged in a conversation with a friend, the cup of coffee on the table affords drinking from it, and my iPhone affords checking my email. Every now and then I unreflectively switch from interacting with my friend to drinking and back to the conversation afforded by my friend. Thus “the context” is not a static pre-given: What is at the foreground and what is at the background for us shifts – depending both on what happens in the environment and on our current needs. It is important to understand how we switch spontaneously from responsiveness to a social affordance to responsiveness to another affordance, and back, because this is what happens in real life all the time.

Are we just “responsive to the socially relevant, expressive behavior of others” (target article, sect. 3.1.1, para. 3) or are we responsive to something broader? Our work on skillful unreflective action suggests that it is the whole field of relevant affordances (social and other) that we are responsive to. This also explains why we switch so easily between interacting with a person and interacting with an object: We are immersed in an integrated field of relevant affordances, each of which can solicit activity. Affordances in the background can solicit activity because they are bodily potentiating. A relevant affordance can generate bodily “action readiness” (Frijda Reference Frijda1986; Reference Frijda2007), that is, the readiness of the affordance-related ability (Rietveld, Reference Rietveld2008). In this way, starting from bodily or skilled intentionality, our perspective avoids an artificial separation between social cognition and nonsocial engagements with the environment.

All this amounts to putting social affordances in context, which is in line with our findings in psychiatry, where we investigate the phenomenology of patients suffering from treatment-refractory obsessive-compulsive disorder (OCD) who are treated with Deep Brain Stimulation (DBS). DBS treatment consists of permanently implanted electrodes that deliver electrical pulses to a target brain region. DBS of the nucleus accumbens shows encouraging results as treatment for therapy-resistant OCD (Denys et al. Reference Denys, Mantione, Figee, Van den Munckhof, Koerselman, Westenberg, Bosch and Schuurman2010). OCD is characterized by the presence of recurrent and anxiety-provoking thoughts, images, or impulses (obsessions), typically followed by repetitive ritualistic behaviors (compulsions) to relieve anxiety. One could interpret compulsions as a disturbance in affordance-responsiveness, the perpetuation of a meaningless act that is an ongoing but inappropriate response to the field of affordances. Interestingly, some patients respond rapidly to DBS and many report profound changes (Denys et al. Reference Denys, Mantione, Figee, Van den Munckhof, Koerselman, Westenberg, Bosch and Schuurman2010). Important changes do indeed concern the social dimension: Patients report increased social interests and communicative interactions. However, patients also report a different interaction with the world in general; feeling more open and less anxious. Some even report a renewed sense of their own body, and more intense perception of the world. This suggests that at least certain kinds of psychiatric disorders may be described by changes or dysfunction in affordance-responsiveness, including responsiveness to social affordances.

There is something right in Schilbach et al.'s suggestion of understanding psychiatric disorders as “disorders of social cognition” (sect. 5.1). However, they are not disorders of just social cognition. From the OCD patients treated with DBS, it becomes very clear that many aspects of engagement with the world change all together: perception, reflection, mood, interests, and social interaction. These phenomenological changes can be understood as changes in their responsiveness to the field of affordances as a whole, not just to the social affordances encountered. This general capability of affordance-responsiveness may correspond to brain activities that heavily interact and need to be understood in rapidly communicating neurocircuitries (Freeman Reference Freeman2000; Friston Reference Friston, Tschacher and Bergomi2011; Friston et al. Reference Friston, Shiner, FitzGerald, Galea, Adams, Brown, Dolan, Moran, Stephan and Bestmann2012; Thelen & Smith Reference Thelen and Smith1994) rather than separate brain areas, which in turn explains the integrated responsiveness to the field of affordances. This general capability of affordance-responsiveness may be directly influenced by brain manipulation such as with DBS.

To conclude, Schilbach and colleagues make an interesting call for a second-person methodology for neuroscience. We also support their broader understanding of social cognition as fundamentally encompassing the implicit, bodily, affective, and contextual aspects of our social interactions. We suggest that a fruitful way to integrate these aspects is to understand social interactions as a form of skilled intentionality. We are bodily responsive to a field of relevant affordances, including social and other affordances. Such a broader account sheds light on how we unreflectively switch between these affordances. Finally, based on our experience with DBS for treating OCD patients, we suggest that psychiatric disorders may affect affordance-responsiveness in general.
