The effects of task complexity, object location, and object type on reaching behavior were examined. Two hundred ninety-two right-handed and 38 left-handed participants (grouped into five age groups) were asked to pick up or pick up and use objects in different regions of peripersonal space. It was found that individuals used their nonpreferred-hand more often in contralateral space than at the midline position. Using an object resulted in significantly more preferred-hand reaches than picking up an object. Furthermore, task complexity, object location, and object type interacted with each other depending upon age group and hand preference.
研究了任务复杂性、目标位置和目标类型对伸手行为的影响。要求 292 名右利手和 38 名左利手参与者（分为五个年龄组）在近体空间的不同区域拿起或拿起和使用物体。结果发现，个体在对侧空间中比在中线位置更频繁地使用非优势手。使用物体比拿起物体导致更多的惯用手伸展。此外，任务复杂性、目标位置和目标类型相互作用，取决于年龄组和手偏好。
