Answer:

d) selection-maturation effect.

Explanation:

Based on the scenario being described within the question it can be said that this could also equally reflect the selection-maturation effect. This term refers to a differential rate of normal growth that occurs between pre-test and pos-tests. Such as is the case in this scenario since the scores have increased drastically between these two stages of the testing period.

Ral has been golfing for most of his life and thinks he's a good golfer. Ral was surprised when his friend asked him to describe
jek_recluse [69]

Answer:

Ral's memory of how to avoid slicing the ball is probably 3. a procedural memory.

Explanation:

Procedural memory is in charge of remembering motor skills, it is the <em>storage of procedures,</em> as the name states.

It is part of the long-term memory and it becomes automatic because once an individual learns how to carry out an action, he/she does not have to think about how to do it again and simply does it.

This explains why Ral cannot describe how he avoids slicing the ball; this information is stored in the procedural memory and is therefore automatic. He doesn't have to think about how to do it anymore.
