Learning transfer occurs when knowledge or skills acquired in one situation affect performance in a different situation. Both positive transfer (improvement) and negative transfer (hindrance) are complex phenomena.
The correct answer highlights that the relationship between the responses required for the two tasks is key. Similarity can lead to positive transfer but also negative transfer if responses conflict. Dissimilarity, while perhaps less direct, also influences how knowledge is applied or misapplied. Therefore, it is the combination of both factors – how responses are alike and how they differ – that largely determines the nature of the transfer.
