Your brother used your computer to complete his homework last night, and now your login password no longer works. What question
frames your problem into a question to help reach a solution? What is wrong with my brother?
Did this computer get a virus?
Why is this computer broken?
Did my brother change the password?
Number 1 is incorrect. Your brother must've asked for your permission to use your computer to complete his homework, and you accepted it.
Number 2 is incorrect. If your computer had a virus, how would you have been able to type in your login details?
Number 3 is also incorrect. The reason would be the same as the previous one.
Number 4 is relevant here. Your brother was the last one using your computer, so you would automatically assume that it was your brother that changed the password.
It is also believed that strong emotions trigger the formation of strong memories, and weaker emotional experiences form weaker memories; this is called arousal theory (Christianson, 1992).
