caused the symbol of hope to take on the deeper meaning of a heavenly hope anchored to the Cross of Christ.

Free Essays on Cross Free Essays on Cross The cross, as a basic design motif, appears in the pottery, weaving, carving, and painting of many cultures. It may be simply decorative, or it may have symbolic meaning. The tau cross, for example, was a symbol of life to the ancient Egyptians; when combined with the circle (as in the crux ansata), it stood for eternity (see Egyptian Art and Architecture). For most ancient peoples the Greek cross was a metaphor for the four indestructible elements of creation (air, earth, fire, and water), thus symbolizing permanence. The swastika, with the ends of its cross bars bent to the right, was common in both the Old World and the New World. It originally represented the revolving sun, fire, or life and later, by extension, good luck. To Buddhists, a swastika represented resignation; to the Jains, it symbolized their seventh saint. To Hindus, a swastika with arms bent to the left symbolized night, magic, and the destructive goddess Kali. In mid-20th-century Germany, the right-facing swastika was the Nazi party emblem (see Buddhism; Jainism; Hinduism; National Socialism). Latin Cross The traditional cross that we recognize and acknowledge for being a cross. The ones you see everywhere you go. The horizontal branch is usually placed about two thirds up on the vertical branch. When looking at it, it resembles a man standing with his arms outstretched. Anchor Cross Many early Christians saw the anchor as a disguised form of the cross. It came from words of St. Paul to the Hebrews, â€Å"We have this as a sure and stead fast anchor of the soul, a hope that enters into the inner shrine.† Those words caused the symbol of hope to take on the deeper meaning of a heavenly hope anchored to the Cross of Christ. The symbol of the Trident was found later than the anchor, but was not widely used as the anchor.

Understanding PTSD Flashbacks

Understanding PTSD Flashbacks A flashback is an intrusive, unintentional, vivid memory of a traumatic event. Flashbacks are one symptom of post-traumatic stress disorder (PTSD). Defining PTSD Post-traumatic stress disorder (PTSD) occurs in the aftermath of a traumatic event, including military conflict,  assault, interpersonal violence, a car accident, or a natural disaster.  PTSD can also occur among first responders,  as well as  people whose loved one experienced a traumatic event. To be diagnosed with PTSD, an individual must experience symptoms in the following four categories  for at least a month after the trauma: Re-experiencing the event. People suffering from  PTSD often re-experience the event in unwanted, unintentional ways, including flashbacks and nightmares.  Avoidance of the event. Someone who is experiencing PTSD will often  try to avoid reminders of the event.Negative thoughts or emotions. The person may experience negative emotions (or a lack of positive emotions), feel self-blame, or lose interest in activities they previously enjoyed.Hypervigilance.  PTSD patients typically feel as thought they are constantly on â€Å"high alert.† They may have trouble sleeping, be irritable, or become easily startled, for example. While many people may develop some of these symptoms immediately after a traumatic event, not everyone who experiences a trauma develops PTSD. What a PTSD Flashback Feels Like Flashbacks can  be incredibly  vivid  and involve  re-experiencing the sights, sounds, and smells that were present during the traumatic event. Some people become flooded with the emotions that they felt at the time of the trauma.  Flashbacks can be so overwhelming and immersive that the person experiencing the flashback may temporarily feel that they have physically returned to the moment of the traumatic event. In some cases, a person experiencing a flashback may behave as though they were back in the traumatic event. Flashbacks can occur as a result of a  trigger- that is, when they notice something in the environment that reminds them of  the traumatic event. However, people can also experience a flashback without being aware of a particular trigger that caused it. Flashbacks vs. Memories Flashbacks occur when individuals involuntarily re-experience a memory of a  traumatic event. Importantly, the psychological definition of a flashback  differs from the common colloquial use of the term. A flashback is  not  simply a â€Å"bad memory. Rather, it is an experience in which an individual actually feels as if they  are re-living parts of the traumatic event. Flashbacks in PTSD are different from intentional memories because they occur without the person trying to do anything to bring back the memory. In fact, psychologist Matthew Whalley and his colleagues have found that patterns of brain activation are different when people are exposed to words that they associate with flashbacks, compared to words that they associate with non-flashback memories. Studies on PTSD Flashbacks   Psychologists have investigated whether it is possible to prevent the development of flashbacks after a traumatic event. Researcher Emily Holmes and her colleagues have suggested that, since flashbacks are often powerful visual images, it may be possible to reduce the severity by distracting the visual system. To test this idea out, Holmes and her colleagues conducted an experiment in which participants watched a potentially traumatizing video.  Afterwards, some participants played Tetris, and others did not. The researchers found that participants who played Tetris only had about half as many flashbacks as the participants who didn’t. In other words, it appears that a neutral activity such as Tetris kept the visual systems in the participants brains occupied, making flashback images less likely to occur. In another paper  by Dr. Holmes’  team, researchers asked emergency room patients who had experienced a traumatic event to participate in a similar study. Some participants played Tetris while others did not, and the researchers found that participants who played Tetris had fewer intrusive memories of their traumatic event over the next week. More broadly, researchers have found that psychotherapy and medication can reduce the severity of PTSD symptoms, including flashbacks. One type of therapy,  Prolonged Exposure,  involves discussing the traumatic event in a safe, therapeutic setting. Another therapeutic technique,  Cognitive Processing Therapy, involves working with a therapist to change ones beliefs about the traumatic event. Researchers have found that both types of therapy are able to lessen the severity of PTSD symptoms. PTSD Flashbacks Key Takeaways Post-traumatic stress disorder is a mental health condition that can occur in the aftermath of a traumatic event.Flashbacks are a PTSD symptom that involve re-experiencing memories of the traumatic event.PTSD flashbacks can be extremely  vivid and may make  individuals feel as though they are re-living the traumatic event.  Several treatments are currently available for PTSD, and new research is investigating whether PTSD flashbacks can be prevented.
