Your friend has just come from a therapist who has recommended eye movement desensitization and reprocessing for posttraumatic stress disorder. Because you are taking a course in abnormal psychology, your friend asks what you think. Based on the literature, what would you say?

Explanation:

It is plausible that my friend is going through trauma and I might not be aware of it. If the doctor suggested the effectiveness of eye movement desensitization and reprocessing (EMDR) for my friend, then I would want to believe that it is the right therapy for PTSD that has been proven as the best for years. Most EMDR will require my friend to sit still and remember the traumatic memory whilst doing an activity that involves her moving here eyes from left to right or up and down. Studies show that the emotions that are exhibited from a trauma will gradually start to decrease if this kind of therapy is delivered in a time period of between six to twelve weeks. Some EMDR experts suggests that these kinds of rhythmic eye movements from left-right help a lot in reducing emotional arousal caused by Trauma while other doctors believe that it does not help. It is up to my friend to try out EMDR and see whether it will work for her. If it does not, we can try other therapies.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
