a disorder of thinking, which manifests itself in the form of unexpected and unnecessary transitions from one thought to another. Although there is no obvious connection between the thoughts after such a transition, or there are only extremely distant connections, yet individually each such thought remains grammatically and logically correct. Slips are sudden and episodic. It is possible to talk about the presence of “slips” only if the violation of the sequence of thinking is short-term and the patient, using help in structuring his activity, can actualize the correct signs and comes to the correct solution to the problem.
