(2) The derivative element of the encodement is the enantiomorph of the facsimile element.
(3) The elements of an encodement are arranged so that the edges of the facsimile element which are nearer to the observer are close to the axis of symmetry of the encodement.
For the stimuli in the fronto-parallel plane both manners of encodement ('bd' and 'db') yield clearly related scores.
The three experiments reported derive their impetus from studies of shape-discrimination learning and are particularly concerned with the mechanism involved in encodement of spatial orientation of random and unfamiliar shapes of lamellae.
lamella 'b' set at 30[degrees] and lamella 'b' set at 150[degrees]) are distinguished by the manner in which the two elements of the postulated encodement are arranged with respect to their axis of symmetry.
(1) the relative strength of the two enantiomorphic elements which each lamella evokes (the presence of two elements does not imply that a lamella is encoded twice; the two elements jointly contribute to the encodement of the lamella and its spatial orientation); and
