There are several methods of implicit measurement. A very valid and wide spread assessment of motives by using the technique of projection are picture story exercises (PSE). Graphology, as theory of inferences on personality and motives by analyses of handwriting, is another one. The presented study examines the commons of these both measurement methods and their prediction of achievement behaviour. So, the achievement motive of 189 students was assessed using the PSE of Heckhausen (1963) and afterwards their handwriting was scored by a categorical system of Ploog (2013). Achievement related behaviour was analyzed with self-reported learning time, learning behaviour and task-choice performance. It is shown that both, implicit motives measured by PSE and graphological variables, deliver information about learning variables.
