ELEMENTAL MODELS 7
Landmarks were enhanced in BC+, participants did not use geometric cues, and the corner that
was correct was the corner that the landmark was situated. The participants used both the
landmark and geometric cues in ABC trials, to select the right corner according to the
assignment corner. Participants were instructed that the choice of the corner was not correct as
the trials were not reinforced. For the analysis purposes, a correct choice was considered to be
the choice of the corner where the sphere and panels were situated.
