Face Recognition Study: Inverted V Upright Faces. Essay

Face recognition study Inverted V Upright faces. Introduction Face recognition is a difficult visual representation depute in large part because it requires differentiating among objects which vary only subtly from each other. This particular face recognition study was expected to suggest that people signalize inverted faces less accurately than upright faces. The study involved sixty different faces observed on a computer screen by a sample of first-year university students. HypothesisThe scheme for this study stated that it is expected that people severalise inverted faces less accurately than upright faces. The null hypothesis stated that there would be no difference in the amount of faces prize regardless of whether they were upright or inverted and that if there was to be some(prenominal) difference that it would be down to chance. Method Participants The sample employ consisted of 15 first-year psychology students of mixed ages. Gender or race held no implication for th is study.The psychology students used participated in the experiment in there seminar groups at allocated times throughout a timetabled week. Materials The materials used for this study consisted of the e-pro computer programme which was used in array to display the faces required for the experiment. Furthermore, the results of the study were interpreted using the SPSS computer software. Procedure For the first part of the experiment, sixty faces, cardinal of which were upright and thirty of which were inverted were displayed on a computer creen for two present moments per face. After each participant had viewed the full sixty faces, a distracter task was then issued to them in order to remove any short-term memory effects on facial recognition. The distracter task consisted of a series of personal questions and lasted for roughly five minutes. Upon completion of the distracter task, the second part of the experiment took place. During the second phase of the experiment, sixty of the previous faces were shown alongside a set of sixty new faces.Participants were asked to say whether or not they recognised the faces from the earlier stage of the task. Results The mean number of recognised inverted faces was 0. 67 with a standard deviation of 0. 07. The mean number of recognised upright faces was 0. 74 with a standard deviation of 0. 05 ? Figure 1 shows the mean value for facial recognition of upright faces to be significantly higher than that of inverted faces t(14) = 3. 55, p= 0. 03Figure 1 Mean values of facial recognition for inverted and upright faces. Discussion The results recorded from this study suggest that our hypothesis that people recognise inverted faces less accurately than upright faces may be correct. However, to be more certain that our hypothesis is accurate, it should be ensured that the experiment is repeated and that in this case is counter-balanced across the whole sample of first-year psychology students collectively and not just withi n their seminar groups.
