Except on assignments, because it looks like you are creating a local
variable.
Example:

class Foo
  attr_accessor :bar
  def bad_assign
    bar = 'baz'
    defined? bar
  end
  def good_assign
    self.bar = 'baz'
    defined? bar
  end
end

foo = Foo.new

foo.bad_assign  # => "local-variable"
foo.bar         # => nil

foo.good_assign # => "method"
foo.bar         # => "baz"
