Permissions allowed or denied at the property level apply only to specific properties. For example, you can set a property-level permission on a User object that allows a particular user, such as Principal Self (that is, the user represented by the object), to change the Home Address property of the User object.
The DSM. Psychologists and psychiatrists use a reference book called the Diagnostic and Statistical Manual of Mental Disorders (DSM) to diagnose psychological disorders. The American Psychiatric Association published the first version of the DSM in 1952. It has been revised several times, and the newest version is commonly referred to as the DSM-IV.
What Psychologists Do. Psychologists study cognitive, emotional, and social processes and behavior by observing, interpreting, and recording how people relate to one another and their environments.
