Body and face symmetry are known to predict human health. In the past, only animals were tested with symmetry for health concerns. Now, it is more common that we check for symmetrical alignments in humans, as well. There are two types of symmetry: Low symmetry and high symmetry. In low symmetry, there is a worse genetic, physical, and mental health associated with non-equal body parts. In high symmetry, it is likely to have more sexual partners and quicker access to romantic partners. More over, humans with a high symmetry have more equal body parts.
The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
