“…In both studies, statistically significant reaction time advantages for the left hand did not depend on making a visually-guided movement to a suddenly appearing visual target. By contrast, Mieschke et al (2001) only find the left hand RT advantage in a visually guided pointing condition. Both of these previous studies utitlised between-subjects designs, which will inevitably be subject to participant-specific sources of noise and cannot capitalise on the difference score approach used in repeated measures analyses, such as those of the current study.…”

“…Similarly to Mieschke et al (2001) for the lift hand condition we only analysed RT data, whereas in the conditions that actually required a reaching movement we examined RT as well as peak velocity (PV) and duration of the movement. Hand x condition repeated measures ANOVAs were run separately on each dependent measure.…”

“…Both Mieschke Elliott, Helsen, Carson, and Coull (2001) and Barthélémy and Boulinguez (2002) measured manual asymmetries in RT in conditions where participants had to reach to unpredictable target locations, or give a simpler finger lift or key press response when target onset was detected. The logic here was that both conditions relied on whatever visuospatial/ attention processes are required for target detection, but that only one condition required planning of a complex movement.…”

“…The logic here was that both conditions relied on whatever visuospatial/ attention processes are required for target detection, but that only one condition required planning of a complex movement. Mieschke et al (2001) compared one group of participants who reached to a target (in one of five possible locations on a horizontal table top), to another who other simply lifted their hand from the start position upon target detection. RTs in the lift group were faster than those in the reach group, and no hand difference was found in the lift group, whereas a left hand RT advantage was present in the reach group.…”

“…This condition is intermediate to detection and point to target tasks in at least two ways. First, an aiming movement to the target surface is required, unlike in the detection tasks used by Mieschke et al (2001) and Barthélémy and Boulinguez (2002). Second, it may be that premotor theories of left hand reaction time advantages do not depend upon de novo computation of reach end point.…”

Abstract:Asymmetries in hand movements have routinely been attributed to properties of the two cerebral hemispheres. In right-handed participants, the non-dominant left hand tends to have shorter reaction times, with the dominant right hand achieving shorter movement durations as well as higher peak velocities. The root cause of the surprising left hand RT effect has been debated, largely in the context of right hemisphere specialization in attention, visuospatial abilities, or 'premotor' processes. Mieschke Elliott, Helsen, Carson, and Coull (2001, Cortex) and Barthélémy and Boulinguez (2002, Behav Brain Res) both tried to dissociate 'premotor' processes explaining the left hand RT advantage, using reaching paradigms where at least one condition required target detection, but no visually-guided aiming movement. Unfortunately the studies obtained conflicting results and conclusions. In the present study, we attempted to re-examine this kind of paradigm with methodological improvements, such as using a task with higher visuospatial demands. Our results demonstrate that whilst RTs are longer as movement complexity increases across three conditions, the left hand RT advantage is present across all conditions -and no significant interaction between hand and condition was found. No significant hand differences were found in peak velocity or duration. These results suggest that the left hand RT advantage cannot be due to movement planning advantages of the right hemisphere, and instead should be attributed to sustained attention/vigilance lateralisation to the right cerebral hemisphere.

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.

The aim of this study was to better understand the mechanisms underlying the motor difficulties encountered by children born very preterm (VPT) without major sequelae from preterm birth. We compared the organization of visuo-manual aiming in preterm and full term (FT) preschool aged children based on performance and kinematics data. Twenty preterm (4 females, 16 males) and 20 sex- and age-matched FT children were divided into two age groups (mean age: 3 years-4 months, and 5 years). Comparison of the performance data showed differences between the older preterm and FT children. Kinematics data revealed differences in movement control between the younger preterm and FT children. The younger FT children did not differ from the older children. In addition, there was an effect of age on both performance and kinematics data for the preterm children only. The pattern of results suggests difficulties in integrating sensory information for movement control in the preterm groups, leading to a delay in the development of visuo-manual coordination. Kinematics analyses may help identify children at risk for poor school performance.
