Question 8: What, if anything, do scientific discoveries about the interpersonal coordination of action reveal about how joint action differs from acting in parallel but merely individually?

Where to Find the Reading?
In some cases the references section already includes a link to help you find the reading.
If there is no link in the references section, start by searching for the title (and, if that fails, by title and authors) on google scholar. If this fails, the library has resources. If those fail, please check first with others on the course. If you still have problems, you may email your seminar tutor.
Glossary
co-representation : Two or more individuals co-represent something if they each individually represent it
and their representations are of the same kind (for example, they are both motor representations).
Co-representation is not metarepresentation: instead of representing another’s representation,
co-representation involves representing the thing represented.
collective goal : an outcome to which two or more agents’ actions are directed where this is not, or not only, a matter of each action being directed to that outcome (Butterfill & Sinigaglia, 2023).
joint action : Many of the things we do are, or could be, done with others.
Mundane examples favoured by philosophers include painting a house together (Bratman, 1992),
lifting a heavy sofa together (Velleman, 1997),
preparing a hollandaise sauce together (Searle, 1990),
going to Chicago together (Kutz, 2000),
and walking together (Gilbert, 1990).
These examples are supposed to be paradigm cases of a class of phenomena we shall call ‘joint actions’.
Researchers have used a variety of labels including ‘joint action’ (Brooks, 1981; Sebanz, Bekkering, & Knoblich, 2006; Knoblich et al., 2011; Tollefsen, 2005; Pettit & Schweikard, 2006; Carpenter, 2009; Pacherie, 2010; Brownell, 2011; Sacheli, Arcangeli, & Paulesu, 2018; Meyer, Wel, & Hunnius, 2013), ‘social action’ (Tuomela & Miller, 1985), ‘collective action’ (Searle, 1990; Gilbert, 2010), ‘joint activity’ (Baier, 1997), ‘acting together’ (Tuomela, 2000), ‘shared intentional activity’ (Bratman, 1997), ‘plural action’ (Schmid, 2008), ‘joint agency’ (Pacherie, 2013), ‘small scale shared agency’ (Bratman, 2014), ‘intentional joint action’ (Blomberg, 2016), ‘collective intentional behavior’ (Ludwig, 2016), and ‘collective activity’ (Longworth, 2019).
We leave open whether these are all labels for a single phenomenon or whether different researchers are targeting different things. As we use ‘joint action’, the term applies to everything any of these labels applies to.

motor representation : The kind of representation characteristically involved in preparing, performing and monitoring sequences of small-scale actions such as grasping, transporting and placing an object.
They represent actual, possible, imagined or observed actions and their effects.
shared intention : An attitude that stands to joint action as ordinary, individual intention stands to
ordinary, individual action.
It is hard to find consensus on what shared intention is, but most agree
that it is neither shared nor intention.
(Variously called ‘collective’, ‘we-’ and ‘joint’ intention.)
task representation : A task representation links a representation of an event,
such as the timer’s ringing, and a motor representation that specifies an action,
such as taking the stew out of the oven, in such a way that if the event occurs,
the subject becomes disposed to prepare and perform the action represented.
(These are perhaps the same as the stimulus–action links involved in
habitual processes.)
The Problem of Joint Action : What distinguishes doing something jointly with another person from acting in
parallel with them but merely side by side?
