With contact between paddles leading to their immediate disintegration\, the doubles-pong task require d team members to decide on each trial who would be the one to actualize t he interception.\nBecause overt communication was precluded\, these decisi ons were informed exclusively by vision of the onscreen movements of paddl es and ball. In three experiments\, manipulating initial conditions (i.e.\ , initial paddle positions) and individual skill differences within teams\ , we examined how teams organized their joint interception behavior. Resul ts revealed that all teams spontaneously demonstrated a division of labor\ , characterized by individual interception domains separated by fuzzy (i.e .\, overlapping) boundaries. While boundary locations could vary over team s within a given experimental condition\, they were nevertheless systemati cally affected for each team by initial paddle positions. Skill difference s between individual team\nmembers did not appear to have such an effect. Overall\, our findings provided converging evidence that\, instead of bein g based on any geometrically-inspired criterion for dividing up space\, th e observed division of space emerged from both team members’ interdepend ent interception behaviors. An action-based definition of the (time-evolvi ng) expediency with which\, at each moment in time\, each player moved tow ards the future interception position allowed predicting which of the two players would end up intercepting the ball and which would abandon the int erception attempt. Overall\, our studies suggest that the decision of who will intercept the ball emerges from an informational coupling between tea m members\, with the division of space\nbeing an emergent result.\n\n  \;\n\nMots-clés : Prise de décision\, Interception\, Action conjointe\, Coordination interpersonelle CATEGORIES:Soutenances LOCATION:Facultés des Sciences du Sport - Amphitéâtre Jacques Paillard\, 163 avenue de Luminy\, Marseille\, 13009\, France GEO:43.235558;5.439621799999941 X-APPLE-STRUCTURED-LOCATION;VALUE=URI;X-ADDRESS=163 avenue de Luminy\, Mars eille\, 13009\, France;X-APPLE-RADIUS=100;X-TITLE=Facultés des Sciences d u Sport - Amphitéâtre Jacques Paillard:geo:43.235558,5.439621799999941 END:VEVENT END:VCALENDAR
