Struggles of children with language impairmentsFor the first time, a new study has looked into how language impairments affect a childs ability to understand and retell a script-based story.
When we experience an event frequently, for example going to a restaurant, we remember the kinds of activities that are part of that event. This is called a script and a number of scientists think that we store information in our brain as scripts. So if you are listening to a story that takes place........Go to the Psychology news blog (Added on 9/23/2007 11:05:04 AM)
