This study investigated the way young children used a cane for displacing an object. In the experiment, 11 children with an average age of 32.3 months were asked to pick up a cane (hooked stick) that was located and orientated differently on each trial. With this cane they had to displace a target-object towards a free-to-choose goal location. The way the children used the cane for transporting the object was not determined by its starting location and orientation relative to the object. In fact, the children preferred enclosing the object in the hook, irrespective of the starting configuration. This contradicts a prediction that follows from an earlier study by Van Leeuwen et al. (1994). Final location of the target object and hand use was influenced by preferences as well as constraining task variables.
本研究调查了幼儿使用拐杖移动物体的方式。在实验中，11名平均年龄为32.3个月的儿童被要求捡起一根拐杖（带钩的棍子），每次试验中该拐杖的位置和方向都不同。他们要用这根拐杖将目标物体移向一个可自由选择的目标位置。儿童使用拐杖搬运物体的方式并非由其相对于物体的起始位置和方向决定。事实上，无论起始配置如何，儿童都更喜欢将物体夹在钩子中。这与范·利文等人（1994年）早期研究得出的预测相矛盾。目标物体的最终位置和手部使用受到偏好以及约束任务变量的影响。
