People may spontaneously follow a routine for looking at a picture album before going to sleep at night. Within ACL 4, they rarely watch TV and they need something to do to settle down.
Individual albums to look at in the evening may reduce troublesome behaviour associated with that time of day because their personal identity is protected by looking at the pictures. Someone to ask questions about their memories may add to their reassurance as they describe them. Telling the same story every day is reassuring for many people. Turn the television off when it is merely a distraction.
