The differences between experts and novices have led to a discussion of surface and structural similarities and transfer. Surface similarity refers to the degree to which the elements describing a situation are identical. Structural similarity refers to the degree to which the two situations share analogous relationships among the elements that describe the situations. Gick and Holyoak (1987) have suggested that comparing situations in terms of their structural and surface characteristics allows for a different analysis of the concept of similarity that can be useful for understanding transfer. Figure 8.6 (appears at the end of the chapter) provides a graphic illustration of their reasoning. The analysis of a transfer task begins by asking two questions. Does the current situation (transfer situation) share surface similarity with previous experiences (learning situations)? Does the transfer situation share structural similarity with the learning situation? The answer to the first question determines the likelihood that some types of transfer will occur because the likelihood of retrieving prior knowledge is directly related to the degree of surface similarity shared by the transfer situation and experiences stored in long-term memory. The answer to the second question determines how our prior knowledge will affect our performance in the transfer situation. When the transfer situation shares a high degree of 27 structural similarity with the recalled learning situation, then positive transfer is likely. However, if the recalled learning situation isn’t structurally similar to the transfer situation, then negative transfer is the likely result. In addition to positive and negative transfer, Figure 8.6 also makes a distinction between near and far transfer. When there is a high degree of surface and structural similarity between two situations then the learner is attempting near transfer. In a near transfer situation, successful (positive) transfer is likely. When the degree of surface similarity between two situations is low, but there is a high degree of structural similarity then the issue is far transfer. The low surface similarity means that people often do not remember facts and procedures that would be useful in dealing with the new situation. For this reason, cognitive psychologists expect far transfer to be a relatively rare event. Can you use the description of transfer presented in the preceding paragraph and Figure 8.6 to explain the following situations?
