Psychology in the News, Revisited
• The diagnosis of mental disorder raises important questions
about personal responsibility in the law and everyday life. When

truly have a disorder that reduces their ability to control their
behavior.
Taking Psychology With You
• Suicide is devastating to the family and friends of those who go
through with it. If you know someone who you feel is suicidal,
take all threats seriously, know the danger signs, ask questions
and get help, and do not leave your friend alone or with methods
of carrying out their intentions. If you are the one contemplating
suicide, help is a phone call away. You will be understood and
you will survive.
