Mental testing and mental training have long remained dominant domains in the work of applied sport psychologists. As a consequence of their work in the domains, numerous tests and tools for mental diagnosis and mental training have been developed. The MTTS (designed and developed by Hackfort; see Hackfort, Kilgallen, and Liu, 2009) is an action-theory-based mental test and training system, in which tests can be used individually or in combination with other setups for mental testing and/or training purposes. The main purposes of the present paper are to elaborate on a MTTS tool and to present and examine a practical application of that tool in the frame of an action-theory-based mental assessment and training approach.     «
