Final answer:
Option D is not an example of proactive interference because it contains unrelated professions that would not likely interfere with the recall of bird-related items from previous trials.
Step-by-step explanation:
The item that is NOT an example of Proactive Interference is:
D. Trial 1: Canary, Robin, Crow Trial 2: Hummingbird, Bluejay, Sparrow Trial 3: Teacher, Doctor, Lawyer.
Proactive Interference refers to when old information hinders the recall of newly learned information. The first three options illustrate trials where the first set of information could interfere with the second and third trials because the information is similar or related. In contrast, option D contains a third trial with professions that are unrelated to the birds listed in the first two trials, which would not likely interfere with the recall of bird-related items, and therefore, does not exemplify proactive interference.
