Three studies evaluated the role of 4-year-old children's agency- and animacy-attributions when learning from a computerized ghost control (GC). In GCs, participants observe events occurring without an apparent agent, as if executed by a "ghost" or unobserved causal forces. Using a touch-screen, children in Experiment 1 responded to three pictures in a specific order under three learning conditions: (i) trial-and-error (Baseline), (ii) imitation and (iii) Ghost Control. Before testing in the GC, children were read one of three scripts that determined agency attributions. Post-test assessments confirmed that all children attributed agency to the computer and learned in all GCs. In Experiment 2, children were not trained on the computer prior to testing, and no scripts were used. Three different GCs, varying in number of agency cues, were used. Children failed to learn in these GCs, yet attributed agency and animacy to the computer. Experiment 3 evaluated whether children could learn from a human model in the absence of training under conditions where the information presented by the model and the computer was either consistent or inconsistent. Children evidenced learning in both of these conditions. Overall, learning in social conditions (Exp. 3) was significantly better than learning in GCs (Exp. 2). These results, together with other published research, suggest that children privilege social over non-social sources of information and are generally more adept at learning novel tasks from a human than from a computer or GC.
三项研究评估了 4 岁儿童在从计算机幽灵控制(GC)中学习时的机构和能动性归因。在 GC 中,参与者观察到没有明显的代理执行的事件,就好像是由“幽灵”或未观察到的因果力执行的。儿童在实验 1 中使用触摸屏,根据三种学习条件以特定顺序对三张图片做出反应:(i)试错(基线)、(ii)模仿和(iii)幽灵控制。在 GC 测试之前,儿童阅读三个脚本之一,确定代理归因。测试后评估确认所有儿童都将机构归因于计算机,并在所有 GC 中学习。在实验 2 中,儿童在测试前没有在计算机上进行培训,也没有使用脚本。使用了三个不同的 GC,代理线索的数量不同。儿童在这些 GC 中未能学习,但却将机构和能动性归因于计算机。实验 3 评估了在没有培训的情况下,在模型提供的信息与计算机提供的信息一致或不一致的情况下,儿童是否可以从人类模型中学习。儿童在这两种情况下都表现出学习能力。总的来说,社交条件下的学习(实验 3)明显优于 GC 中的学习(实验 2)。这些结果与其他已发表的研究一起表明,儿童优先考虑社交而非非社交信息源,并且通常更擅长从人类而不是从计算机或 GC 学习新任务。
