在20世纪60年代，Bandura和他的同事们开展了一系列着名的观察学习研究，称为Bobo Doll实验。在第一个实验中，学龄前儿童接触到攻击性或非攻击性成人模型，看他们是否会模仿模型的行为。该模型的性别也各不相同，一些儿童观察同性模型，一些儿童观察异性模型。在激进的情况下，该模型在孩子面前对于膨胀的Bobo娃娃进行口头和身体攻击。在接触模特后，孩子被带到另一个房间玩一系列极具吸引力的玩具。为了让参与者感到沮丧，孩子的游戏在大约两分钟后停止了。那时，孩子被带到第三个房间，里面装满了不同的玩具，包括一个Bobo娃娃，在那里他们可以在接下来的20分钟内玩耍。研究人员发现处于侵略性状态的儿童更有可能表现出口头和身体上的攻击行为，包括对波波娃娃的攻击和其他形式的攻击。此外，男孩更有可能比女孩更具攻击性，特别是如果他们暴露于侵略性的男性模特。

In the 1960s, Bandura and his colleagues conducted a series of well-known observational learning studies called the Bobo Doll experiment. In the first experiment, preschoolers were exposed to aggressive or non-aggressive adult models to see if they would mimic the behavior of the model. The gender of the model is also different, some children observe the same-sex model, and some children observe the heterosexual model. In the case of radicals, the model makes verbal and physical attacks on the inflated Bobo doll in front of the child. After touching the model, the child was taken to another room to play a series of very attractive toys. In order to frustrate the participants, the child’s game stopped in about two minutes. At that time, the child was taken to the third room, which was filled with different toys, including a Bobo doll, where they could play for the next 20 minutes. Researchers have found that children in aggressive conditions are more likely to exhibit aggressive head and body attacks, including attacks on Bobo dolls and other forms of attacks. In addition, boys are more likely to be more aggressive than girls, especially if they are exposed to aggressive male models.
