“…Movement duration had the same pattern of adjustment across the prior intentions for all age groups, with a general pattern that for prior intentions where movement duration was shorter (throw < loose place < tight place < lift). A change in movement duration across prior intentions is in line with previous studies (Egmose & Køppe, 2018;Marteniuk et al, 1987;Wilmut et al, 2013a). It was the other three kinematic measures (peak velocity, time to peak acceleration and deceleration period) where we saw marked differences between the age groups in terms of second-order planning for prior intention.…”

Second-order planning, planning which takes into account imminent and subsequent task demands, has been shown to be essential during everyday movement. For example, the kinematics of a 'reach to an object' action have been shown to be linked to the intended goal for the object (the prior intention). However, it is unclear whether this type of second-order planning for prior intention is preserved during aging, or indeed how this differs across the adult lifespan. Kinematics of a reach action preceding four prior intentions, place in a 'tight' hole, place in a 'loose' hole, throw or lift were measured in 122 aged from 20-81 years. The kinematics of the reach movement demonstrated that all participants tailored their reach movement to the prior intention, with the deceleration period of the reach discriminating across groups. The 20s and 30s group showed a different deceleration period during the reach for tight versus loose place prior intentions, this was not seen after 39 years of age and the 70+ group showed no discrimination across the deceleration period for the four prior intentions. When considering movement efficiency of the place actions we found it could be predicted by age and that this relationship was mediated by discrimination across the deceleration period. This study demonstrates that a clear difference is seen in the way in which second-order planning is used across the lifespan and that this has implications for movement efficiency.

“…The 40-69 year-olds discriminated between place and throw which is most commonly found (Egmose & Køppe, 2018;Marteniuk et al, 1987;Weir et al, 1998) but lacked the discrimination between the two place movements. Finally the 70+ group demonstrated no change in deceleration periods for any of the four prior intentions.…”

“…A meta-analysis based on 39 reachto-grasp studies supports in fact such a division. Overall, Egmose and Køppe (2018) found extrinsic properties, such FIGURE 8 | (left) For the first block of trials, the estimated adjustment time based on LMM analysis for the interaction between the properties glossiness and hardness as based on the pre-reaching ratings.

“…Besides recording maximum velocity (peak velocity) in reaching and transportation movements, we were especially interested in the adjustment time period in reaching, that is the deceleration period between the peak velocity of the reach and the moment of object contact. For the reason that such temporal phase reflects movement planning based on the object's identity rather than its location alone (Pryde et al, 1998;Egmose and Køppe, 2018; the term adjustment time is originally used by Rocha et al, 2013). We were also interested in the size of the maximum grip aperture (MGA) during reaching, and how early the MGA appeared for the different types of material properties when reaching for the cups.…”

The current study examined the role of visually perceived material properties in motor planning, where we analyzed the temporal and spatial components of motor movements during a seated reaching task. We recorded hand movements of 14 participants in three dimensions while they lifted and transported paper cups that differed in weight and glossiness. Kinematic-and spatial analysis revealed speed-accuracy trade-offs to depend on visual material properties of the objects, in which participants reached slower and grabbed closer to the center of mass for stimuli that required to be handled with greater precision. We found grasp-preparation during the first encounters with the cups was not only governed by the anticipated weight of the cups, but also by their visual material properties, namely glossiness. After a series of object lifting, the execution of reaching, the grip position, and the transportation of the cups from one location to another were preeminently guided by the object weight. We also found the planning phase in reaching to be guided by the expectation of hardness and surface gloss. The findings promote the role of general knowledge of material properties in reach-to-grasp movements, in which visual material properties are incorporated in the spatio-temporal components.

“…More recently, the social goal of an object-directed motor action was also found to influence movement kinematics (for reviews see [26][27][28][29][30]. A number of studies have indeed revealed that an object-oriented motor action performed with a social goal, i.e.…”

Voluntary actions towards manipulable objects are usually performed with a particular motor goal (i.e., a task-specific object-target-effector interaction) and in a particular social context (i.e., who would benefit from these actions), but the mutual influence of these two constraints has not yet been properly studied. For this purpose, we asked participants to grasp an object and place it on either a small or large target in relation to Fitts’ law (motor goal). This first action prepared them for a second grasp-to-place action which was performed under temporal constraints, either by the participants themselves or by a confederate (social goal). Kinematic analysis of the first preparatory grasp-to-place action showed that, while deceleration time was impacted by the motor goal, peak velocity was influenced by the social goal. Movement duration and trajectory height were modulated by both goals, the effect of the social goal being attenuated by the effect of the motor goal. Overall, these results suggest that both motor and social constraints influence the characteristics of object-oriented actions, with effects that combine in a hierarchical way.
