“…Accordingly, our findings provide evidence for the reactivation of limb-specific sensorimotor parameters within identified areas of bilateral PPC and right-hemisphere POp. This model not only accounts for our fMRI-RS results, but also the behavioral RT advantage we observe for performing successive actions with the same versus alternate hand (see also Valyear and Frey, 2014), as well as prior demonstrations of hand selection biases in favor of recent hand-use history (Rostoft et al, 2002; Weiss and Wark, 2009). …”

The processes underlying action planning are fundamental to adaptive behavior and can be influenced by recent motor experience. Here, we used a novel fMRI Repetition Suppression (RS) design to test the hypotheses that action planning unfolds more efficiently for successive actions made with the same hand. More efficient processing was predicted to correspond with both faster response times (RTs) to initiate actions and reduced fMRI activity levels – RS. Consistent with these predictions, we detected faster RTs for actions made with the same hand and accompanying fMRI-RS within bilateral posterior parietal cortex and right-lateralized parietal operculum. Within posterior parietal cortex, these RS effects were localized to intraparietal and superior parietal cortices. These same areas were more strongly activated for actions involving the contralateral hand. The findings provide compelling new evidence for the specification of action plans in hand-specific terms, and indicate that these processes are sensitive to recent motor history. Consistent with computational efficiency accounts of motor history effects, the findings are interpreted as evidence for comparatively more efficient processing underlying action planning when successive actions involve the same versus opposite hand.

“…Specifically, previous findings have shown that hand selection tendencies are sensitive to recent history for a ball catching task with 4 year-old children (Rostoft et al, 2002), and for a grasping and feeding task with cotton-top tamarins (Weiss & Wark, 2009). While consistent, the current findings significantly extend these previous results.…”

“…To our knowledge, only two previous studies have been carried out, and neither involved adult humans. Rostoft et al (2002) used a ball catching task with 4 year-old children and showed hysteresis for hand selection; which hand was used for catching was sensitive to the direction in which balls were delivered (leftward or rightward), biased in favor of using the same hand according to recent history. Likewise, Weiss and Wark (2009) studied cotton-top tamarins and showed hysteresis for hand selection according to the progressive direction of presentation of food items for grasping.…”

Action selection processes such as those that underlie decisions about which hand to use for upcoming actions are fundamental to adaptive motor behavior. Previous research has shown that people grasp objects in ways that reflect anticipated task demands as well as recent movement experience. However, very few studies have addressed the possible influence of recent motor history on hand selection. In the current study, participants grasped and placed objects using either their left or right hands. The results showed faster response times to initiate successive actions when hand was repeated, even when those actions involved distinct grasp postures and object placement movements to distinct locations. Conversely, no such planning advantage was observed for repeated grasps for successive actions made with opposite hands. The findings are consistent with the idea that choices about which hand to use in the present are influenced by which hand was used in the recent past. When the same hand can be used for successive actions, planning is made more efficient, presumably because the motor parameters that specify which hand to use can be recalled from recent memory rather than formulated anew. The findings indicate that hand selection is sensitive to recent movement experience and provide novel support for computational efficiency accounts of motor history effects.

“…It is unlikely that skill alone accounts for this age difference: When thrown a ball from different directions scaled from the extreme right to the extreme left, 4-year-old children use their preferred right hand up to a well-defined position located to the left of the midline. Less-skilled children tend to use their preferred right hand more than the more skilled ones to catch the balls delivered to the left (Rostoft, Sigmundsson, Whiting, & Ingvaldsen, 2002); however, the developmental age trend in crossing the body midline is not linear: Six-to 11-yearold children use their preferred right hand even in the left hemispace more consistently than 3-to 7-year-olds, but also more consistently than adults . As for adults, left-handers do not respond with their preferred hand as consistently across positions as righthanders .…”

Influence of object spatial location and task complexity on children's use of their preferred hand depending on their handedness consistency

The goal of the present study was to compare the use of the preferred versus the nonpreferred hand in children performing two tasks of different levels of complexity, in various positions in space. Right-handed and left-handed consistent children were compared to their inconsistent counterparts. The results showed that the general tendency to use one's preferred hand to grasp an object is more or less pronounced depending on the object's spatial location and the task's complexity. The children used their preferred hand more often even when the object was presented contralaterally, and did so to a greater extent during the more complex task. Inconsistent-handers were more likely to shift to using their nonpreferred hand when the object was presented to this hand's side. Finally, we found that the influence of handedness consistency on hand use for the spatial positions varied with the complexity of the task. These results favor a view of handedness as a dynamic process in which motor preferences interact with task demand, probably through task-related attention.
