Parietal Lobe Study

Improved Essays
It’s understandable why individuals get weary when visiting relatives undergoing neurological rehabilitation; it’s difficult to predict how they will react and often innocent intentions can be met with a harsh scolding. However, a new study suggests that a simple change in body language can have radical effects on the responses you receive and offers new rehabilitation options for patients.
Despite impairment of the left visual field in patients with right parietal lobe damage, what is considered their blindside may in fact not be as blind as initially expected. Seeming uncomfortable may inadvertently lead to fearful body language being displayed and increase the likelihood of detection, regardless of the position in relation to the patient.

It’s important to note that the parietal lobe is responsible for interpreting visual information and this was Tamietto’s reasoning for involving this type of patient.
For one hour, each of the patients was briefly shown a photo which offered either happy, fearful or neutral body language and then asked which visual field the stimulus which they detected was shown. Images appeared in either both the left visual field and right visual field, or only one side.
Results concluded that fearful body expression was spotted more often. Even when a happy or neutral image was placed in the stronger, right visual field, if a fearful image was placed in the left it would be seen first – meaning attention blindness was overcome.
The emotional aspect of Tamietto’s study is quite innovative; “I wanted to expand upon Downing’s original findings and discover the reason why attention is drawn to detect faces and bodies more than other objects.” Tamietto’s study builds on the foundation of Downing’s 2003 study where Downing revealed that attention detects bodies and faces faster and more frequently than any other object presented but neglected to attribute probable emotional influence on detection.

    Following stimulus presentation, participants were required to discriminate whether the target face had a direct or an averted gaze as quickly and as accurately as possible, using a two-button press with their index and middle fingers of their dominant hand. Responses were made using the b and m keys of a standard keyboard, which were counterbalanced across participants. The next trial started 1000 ms after the end of stimulus presentation, regardless of whether a response was made or not. Before the experimental session, 9 practice trials (one for each possible stimulus location) were presented to familiarize participants with the stimuli and…

    Indeed, even the competing stimuli are switched rapidly between the two eyes in humans, binocular rivalry still produced its normal slow alternation of perceptions. The discovered persistence of gradually dynamical rivalrous perceptions when stimuli are switched powerfully suggests that binocular rivalry occurs as a consequence of alternate stimulus representations compete within the visual pathway. Binocular rivalry thus affords an opportunity to study how the visual system decides what people see even when both eyes see the almost same thing (23). However, a general, non-selective reduction in affectability during the suppression of a stimulus is not selective to binocular rivalry, but rather can likewise occur when seeing (non-dichoptically) ambiguous figures (“Single Units”…

    The human brain is the control center of the body. It is split into many different parts, each with their own distinct function. Some parts of the brain complement and assist the other parts in their tasks. The brain, while being vital to the proper functioning of animals, is quite frail, and even a small amount of damage can seriously impair it from working normally. Any part of the brain can be damaged, and depending on the location of the damage and its severity, the effects will vary.…

    Is it possible that the theory be true, the human mind can extend beyond the psyche and body ? Rupert Sheldrake, a biologist and author, takes on the challenge of creating experiments to prove, despite contrary beliefs, that we do live in a world surrounded by the ''paranormal'' that may actually be explained as ordinary. One of the many topics he took interest in is, whether or not an individual can sense if someone is staring at them from behind.

    Thomas Nagel, in ‘Brain bisection and the unity of consciousness’ suggests that if persons are to be explained in terms of minds or consciousness, this might seem to cast doubt on the coherence of the concept of a person. In this sense, the brain bisection data + the psychological theory of personal identity might seem to lead to skepticism about persons. 1 Structure and Function The brain has two cerebral hemispheres, which are connected via the corpus callosum, which can be thought of as an information pathway between the two hemispheres. The two hemispheres are connected differently to the rest of the body.…

    Monali Joshi, Group 8. Human Visual System Eyes are the entry purposes of the light that conveys the visual data about the onlooker's surroundings into the human visual system. The approaching light is consumed by the photoreceptors in the retina and changed over to electrochemical signs, and these signs are transferred to the resulting systems of the visual pipeline. The photoreceptor cells change over light into electrochemical signals, and are separated into two sorts, rods and cones, named for their shape. Rod cells are in charge of our night vision, and react well to diminish light. Poles are discovered for the most part in the fringe locales of the retina, so a great many people will find that they can see better during the evening on the off chance that they center their look simply off to the side of whatever they are watching.…

And, Tim states that he “couldn’t understand her” (220). For Tim or Timmy, a nine-year-old boy, it would be hard to understand Linda who was smiling while watching a corpse movie.

    Emotional Attentional Blink and Emotion Induced Blindness When talking to a layman about an emotion induced blindness (EIB), one would try to explain it as not being able to see an item because of a distraction caused due to emotional effects. For example – when a driver might not be able to see a scooter coming from the front because of an accident that had happened in front of him as well. So this accident is the negative distractor to the target scooter which must be attended in order to drive safely. The researches is this area makes a clearer understanding about the emotion induced and surprise induced blindness’s.

    In his article “The Naked Face,” Malcom Gladwell outlines Ekman’s psychological view of face reading. The well renowned psychologist believes that the face is the best evidence a person has to offer about their emotions because most facial expressions are not made consciously. The face can be unpacked by every separate expression that pertains to a universal meaning. On the other end of the spectrum, the semiotic view proposed by Wierzbicka’s sees the face as a network of signs. And while there can still be universal meanings in facial expressions, this view is more aimed towards how the signs of the face interact with each other and the environment to create a unique meaning.…
