accessible information. You can become aware of this information once your direct your attention to it. Think of this as memory recall. You walk down the street to your house without consciously needing to be alert to your surroundings. You can talk on the cell phone and still arrive home safely. You can easily bring to consciousness the subconscious information about the path to your home. You can also easily remember phone numbers that you frequently use.
It is possible that some of what might be perceived to be unconscious becomes subconscious, and then conscious (e.g. a long-forgotten childhood memory suddenly emerges after decades). We can assume that some unconscious memories need a strong, specific trigger to bring them to consciousness; whereas, a subconscious memory can be brought to consciousness more easily.
