Everyday we encounter new and familiar faces. We are able to distinguish our mother’s face from a stranger’s face due to the facial recognition processes that we have stored in our brains. Facial recognition is one of the many processes of object-recognition. Many of us are not aware of the brain’s role in facial recognition because it is a process that we are not consciously doing. Face recognition differs from object recognition in a few ways. That is why those who suffer from prosopagnosia are still able to recognize and distinguish everyday objects like a fork from a spoon. An idea proposed by Diamond and Carey states that in order to recognize objects we need first-order relational information. First-order relational information is information about the …show more content…

Second-order relational information involves comparing the first-order analysis to facial features of a “typical” or “average face.” Therefore, because second-order relational information involves the aspect of comparison, it is heavily influenced by experience. The idea of the “typical” or “average face” is built up through out our lifetime and affected by our own experiences (p.122). Once again, this idea seems like a similar concept known as top-down processing which is also used in object recognition. Top-down processing is also influenced by our experience and is a faster way of recognizing objects compared to bottom-up processing. Another unique characteristic of facial recognition is that it is processed holistically. This was proven by the fact that when a face is inverted it negatively affects our ability to effectively recognize the face (p.122). For us to be able to recognize a face we must be able to see it in its original and whole pattern, which would be an upright position. This is not the case with object recognition, we are able to turn an object upside and still be able to recognize

Sometimes we could be very sure about what we see, but actually we aren’t seeing everything we are surrounded of or the whole picture. For example, when someone is focusing his whole vision on something or a place and something could happen next to him, but he couldn’t notice it because his entire attention was focusing on something. During the past decade, lot of researchers have done some experiences and studies to know how people react to these experiments and understand how our vision works. These experiments were about asking people to focus on some subjects while they put some other things that are clearly visible for them, but the observers report that they haven’t seen any other things in the experiment. Over the past years, researches

Since the beginning of science the brain has been a mysterious curiosity to man. The term “neuroscience” only dates back to the 1970’s, but the study of the brain began not too long after figuring out what science was. As technology has progressed over time, neuroscience has undergone significant changes to become what it has today. New findings and discoveries are always changing what we know, or what we think we know, about the brain. In the collection of stories by Oliver Sack entitled, The Man Who Mistook His Wife for a Hat, we see those with neurological diseases suffering, with their attempts to cope these diseases and the conclusions that Dr. Sacks makes on their conditions.

People have always been judged since the beginning of time. From the pitch of their voice all the way to the way they walk. It is sometimes a first instinct for many people and appearances can also be the determining factor for many positions. Although, the most common way people are judged is by their appearance, which is completely inhumane since nobody is perfect. So it obviously isn’t fair to judge by physical appearances alone.

The reliability is a consequence of being able to visualize the other member's physical identifiers besides their face as well as indicate the exact location of the other individual. Hence, it is clear to see that distinguishing facial features not only facilitate social growth and complexity; they also facilitate the evolution of the visual faculties. Since visual processing comprises one of the most brain-intensive biological functions1, distinguishable facial features should characterize primates with larger

Title: Mental Rotation Experiment: The effect of Gender on Mental Rotation Reaction Time Introduction: Mental rotation is an important function of visual representation in the human brain when dealing with misoriented stimuli, which is the ability to rotate two and three-dimensional objects in one’s mind. In everyday life, people’s ability to recognize faces and objects from unconventional perspectives stems from their ability to mentally rotate objects. The earliest experiment to research on the concept of mental rotation was by Shepard and Metzler (1971). In the classic experiment, participants were presented with drawings of pairs of two-dimensional figures and three-dimensional cubes that were asymmetrically assembled.
