    Symmetry is a salient feature of the environment around us. Symmetrical faces are perceived as being more attractive than asymmetrical faces, and people are faster to detect patterns when they have more than one axis of symmetry. A preference for symmetry has been demonstrated in various animal species, in addition to humans, and evidence suggests that symmetry is processed by a network as opposed to a single area of the brain. The purpose of this study was to test the effects of varying levels of symmetry on performance on a visual search task, using white lines on a grey background. The goal was to find the target line among a set of 35 distractors. An algorithm was used to return four levels of symmetry, which were applied to the lines. The dependent variable consisted of response times and proportion of correct responses. The results of this study indicate that symmetry does not significantly affect response times or proportion of correct responses on a visual search task. Future studies could examine whether areas previously implicated in symmetry processing are also involved in a task like the one presented here. A more realistic setting, as well as varying conditions and gender differences, could also be studied.
