Relationships between spatiotemporal outcomes, discrete actions and climbers intentions.

Activity state	Limb activity (A) combined with spatial (GIE) and temporal (IMR) outcomes	Function (individual intentions)
Immobility	A: All limbs stationary and: 1. IMR ↑ and GIE ↓	1. Passive recovery (Seifert et al., 2013a); Visually explore (Nieuwenhuys et al., 2008; Sanchez et al., 2012); establish base of support.
Active recovery	A: 1 limb moving and behind the body: 1. IMR ↑ and GIE ↓	1. Relieve the forearms, apply chalk (Fryer et al., 2012); Visually explore (Sanchez et al., 2012).
Postural regulation	A: All limbs stationary and: 1. IMR ↓ and GIE ↑ 2. IMR ↓ and GIE ↓	1. Exploration of different body orientation(s) (Cordier et al., 1993, 1996; Seifert et al., 2015). 2. Use of different body orientation(s).
Grasping	A: 1 limb moving and: 1. IMR ↑ and GIE ↓	1. Preparation for hold use (Fuss and Niegl, 2008; Boulanger et al., 2016).
Grip change	A: 1 limb moving and: 1. IMR ↑ and GIE ↑	1. Explore hold grasp technique (Boulanger et al., 2016).
Reaching	A: 1 limb moving and: 1. IMR ↑ and GIE ↓	1. Change holds.
Reach and withdraw**	A: 1 limb moving and: 1. IMR ↑ and GIE ↓ 2. IMR ↑ and GIE ↑	1. Efficient exploratory reach (Seifert et al., 2015). 2. Inefficient exploratory reach (Seifert et al., 2015).
Traction	A: ≥1 limb moving and: 1. IMR ↑ and GIE ↓ 2. IMR ↓ and GIE ↑	1. Movement using face-on body position (Fuss et al., 2013). 2. Movement with body roll (Fuss et al., 2013).
Chaining movements in succession	A: ≥1 limb moving and: 1. IMR ↓ and GIE ↓	1. Fluent performance (Cordier et al., 1996).

IMR ↑, means the individuals is more immobile; IMR, ↓ means the individual is more mobile; GIE ↓, means the movement is less complex; GIE ↑, means the movement is more complex.
