Psychology according to the levels-of-processing theory, if jon wanted maqsood to remember the sentences "at first, it is better to run than to walk, " "birds seldom get too close," and "a rock can be used as an anchor," he should

tell Maqsood the sentences all refer to kite-flying.              

Explanation:

Levels of processing theory was identified by Robert  Lockhart and Fergus  Craik in the year 1972. It focuses on the theories of memories that suggests separate stages for working, sensory and long-term memory.    

It gives importance to depth of the processing that is involved in our memory, and predicts deeper information that is processed and a memory trace will last longer.

Thus according to the levels-of-processing theory, Jon should tell Maqsood that the sentences all refer to kite-flying.
