PSY 200 Short Report: Brain Asymmetry The prediction in this experiment was that people would say the picture with the younger half on the left appears younger, disregarding whether one is left handed or right handed. This experiment on brain asymmetry was to test people on which side of a chimeric face appeared to look younger. The images were identical and just mirror images of each other with the opposite side of the face shaded. At the beginning I was asked to verify whether I was left handed or right handed. Then there were two chimeric photos on the computer screen at once and I was asked to press the button corresponding to which face looked younger. The stimuli were the faces that I was looking at and analyzing. The task was to press the key corresponding to which face (top or bottom) that I thought appeared to look younger. The independent variable in this experiment was the construction of the chimeric faces. There were only two faces shown alternating, the sides of the faces that were shaded alternated as well. The dependent variables were if

Unformatted text preview: you were right handed or left handed, and the positioning of the pictures; which chimeric face was on top or bottom. The class results were that 63.47% of right-handed people and 58% of left handed people recorded that the left side of the face appeared younger. These results matched the prediction of the experiment. The only notable difference from the prediction was that a higher percentage of right-handed people thought the left side look younger than the left-handed people did. A possible reason for this is because for a right-handed observer, the right hemisphere tends to be more strongly involved in judgments about faces than the left hemisphere. Left-handed people do not show as strong differences between the left and right hemispheres, that is why left-handed people had a lower percentage than the right-handed people. My results were in unison of the class average, 71% of my choices were with the younger half face on the left....
