The Is A Severe Disorder

Prosopagnosia, also called face blindness, is a neuropsychological condition that refers to impairment in the recognition of faces. Although prosopagnosic patients suffer from other types of recognition impairments (place recognition, car recognition, facial expression of emotion, est.), they experience face recognition problems above or over other types impairments. Prosopagnosia occurs without intellectual, sensory or cognitive impairments; in other words, people with prosopagnosia can still recognize people from non-facial cues. They cannot recognize familiar people by their faces alone, and often use alternative routes to alleviate the effects of this impairment. These routes include

Tamika comes to a psychology clinic with complaints of poor concentration. As she was talking with the psychologist, she spoke very rapidly and it was difficult to follow her train of thought. Tamika reported that she felt invincible and had not slept for three days since she had been very busy with various tasks. She also reported that in the past, she had frequently experienced periods of time that she felt “down”.

1. Differentiate between sensation and perception. Explain the importance of separating these concepts. The differences between sensation and perception is that sensation is the elementary elements that, according to structuralist, combine to create perception. Whereas, perception is the conscious sensory experience (Goldstein, 2014). This student has always looked at sensations as those things in a persons’s environment that one can see, hear, smell, touch, taste, and feel. On the other hand perception is how a person’s brain will interpret what is seen, heard, smelt, felt, or touched.

The term sensation is used when referencing the process of sensing the environment through taste, touch, sound, smell, and sight (Goldstein, 2014). Moreover, it is the process that occurs once the sensory receptor experiences stimulation, which in turn produces nerve impulses that are sent to the brain to be processed in its raw form, then perception comes into play (Goldstein, 2014). Perception is used to describe the way people interpret these sensations and tries to make sense of everything around them on a daily basis. Perception is the occurrences of the brain

Only perception is used as a synonym for sensing, although there are many distinct differences. Perception can be both passive and active.

Imagine lacking the ability to recognize the familiar face of a loved one or spouse. Or having to rely on voices, clothing, and certain attributes of that individual in order to have some kind of knowledge on who they actually are. This condition is defined as Prosopagnosia; known as face blindness or facial agnostic. According to Barton (2008), it was first described as a consequence of cerebral damage by Quaking and Bordello in 1867. This term comes from the Greek word “face” and “lack of knowledge.” Stated by the National Institute of Neurological Disorders and Stroke (2007), Prosopagnosia is anticipated to be the result of damages, abnormalities, or destruction in the right fusiform gyrus; part of the brain that controls the perception of faces and the functionality of memory in the neural system. This deficit can be present from birth, the result of a stroke, a traumatic brain injury, or neurodegenerative diseases. In order to help an individual with Prosopagnosia, it is essential to develop compensatory or redeeming strategies, as well as the use of clues or attributes to help them better identify individuals.

Perception: a process by which individuals organize and interpret their sensory impressions in order to give meaning to their environment.

Prosopagnosia is defined as the difficulty in recognizing an individuals face; it is broken down into 3 main types; Apperceptive prosopagnosia, associative prosopagnosia and developmental prosopagnosia. Perception is an important aspect when recognizing faces, without recognizing the stimulus (face) you would not be able to identify a person. Therefore the individuals who sufferer from this disorder is unable to accurately recognize a face whether that be the face of a familiar person such as a family member or close friend, the face of a famous person, or even their own face. This paper will look at prosopagnosia in greater detail, it will explain the 3 main types, as well as give insight as to why face recognition is important in our

Sensation is the process by which sensory receptor neurons detect information and transmit it to the brain. Perception refers to the process of taking in, organizing, and interpreting sensory information. Perception is understanding what is said to you, knowing that the odor you have detected is a steak or chicken barbecue, etc…( Sigelman and Ryder, 157-158). Yes, there are several aspects to reconsider with an unlimited budget for redesigning

Agnosia is defined as the inability to recognize objects through the processing of sensory information, which means there is no deficit in semantic memory or problems with naming objects. An individual suffering from agnosia still possesses all the relevant semantic information tied to a precept, but they cannot recognize the precept when it is presented to them and therefore trigger the recall of said information. There are many types of agnosia, but this essay will focus on visual object agnosia and prosopagnosia. The former is the inability to recognise objects: patients suffering from visual object agnosia do not have impaired vision, and in some cases can even copy the object they are seeing (patient H.J.A., Humphreys & Riddoch, 1987) or draw it from memory (patient D.F., Milner & Goodale, 1992), but are unable to recognize it when they see it. In the latter, prosopagnosia, patients cannot recognise faces of familiar individuals, and have to rely on other characteristics such as their voice or clothing to recognize them. Patients suffering from prosopagnosia can either acquire it through a lesion in relevant brain areas (acquired prosopagnosia) or for less understood reasons have it from birth, in which case it is termed developmental prosopagnosia. The study of patients with agnosia is integral to the field of visual recognition, as the specifics of their deficits can provide great insight into the ways our brain processes information; for example, the location of
