Subjects classified stimulus patterns into positive or negative instances of the concept according to either an attribute identification (AI) problem or a rule learning (RL) problem. Four types of stimulus materials were used: verbal stimuli (V), geometric stimuli (G), or two combinations of these modes, verbal geometric (VG) or verbal colored (VC). The only main effects that were significant were the Type of rule and Type of problem. Some interactions were obtained between these factors and the stimulus mode employed.
