Activity 1 (Textbook Page No. 87)

Answer:
We remember some incidents from the past clearly when they are a part of our long-term memory. Similarly, we cannot remember certain incidents from the recent past whey they form a part of our sensory or short-term memory.



Activity 2 (Textbook Page No. 87)

Why does this happen? 25 workers used to work in Thomas Edison’s Bulb and Phonogram unit of industries. There was a huge tree near his company. After 6 months, Edison asked his workers about the huge tree but not a single worker could give information about that tree. Why do you think this happened despite seeing the tree every day?
Answer:
I feel the none of the workers could give information about the tree near their company since it was a part of their sensory memory, i.e., they perceived the stimulus (tree) with sense organs but did not rehearse it enough for it to become a part of their long term memory.
