Comprehensive reading is a developed skill necessary for survival in society. This complex natural ability, for the most part, is taken for granted, especially when the visual stimulus has a natural, upright position. This study addressed the idea of imagined spatial operations, and was specifically interested in the time required to read a list of syllables, relative to the degree of rotation. In this experiment, participants were timed as they pronounced consonant-vowelconsonant (CVCs) of varying orientations and levels of meaningfulness. A significant interaction was found between orientation and meaningfulness. Mean response times demonstrated that the 180° position required the longest mental rotation in the low meaning condition. This same result was not evident in the high meaning condition; participants actually took longest to rotate CVCs from 270° to upright. It is believed that in these conditions the preceding list biased participants to rotate the CVCs through a longer (counterclockwise) rather than the shorter distance( clockwise).
