While it may seem easy to be able to determine whether a Gabor patch is tilted to the left or right while quickly flashing on the screen, it's not that easy. Previous researchers have studied how working memory can affect a person's ability to complete tasks. Other literature reviews include how the human visual system tracks changes and notices differences in stimuli. Finally, previous literature on humans who completed a task similar to that of the participants in this study, which involves studying Gabor patches. The first study, conducted by Socchia, Cicchini, and Triesch (2012) examines participants' working memory to see if there is a relationship to how an object is positioned. Socchia, et al. (2012), conducted two different experiments to see if there was any relationship between the orientation of an object and working memory. For the first experiment, participants had to complete two separate tasks. In the first task, participants were shown a Gabor patch to memorize and then had to correctly remember the location (Socchia, Cicchini, & Triesch, 2012). The aim of the second task was for participants to carefully observe the stimuli and notice any changes. The researchers found that the participants were able to perform the task sufficiently (Socchia, et al., 2012). The purpose of conducting the next experiment was to see if the first experiment was influenced by the participant's cognition (Socchia, et al., 2012). The researchers had recruited new participants and changed the appearance of the stimulus. For the second task, participants had to use their left hand to indicate when the Gabor patch changed contrast (Socchia, et al., 2012, p. 52). The results of the second experiment were close to the results of the...... middle of paper......ts of Tilt Adaptation. Seeing and Perceiving, 24 (1), 37-51. Lapid, E., Ulrich, R., & Rammsayer, T.
