The study focused on two cognitive tasks widely used by experimental psychologists. One is mental rotation — mentally rotating a complex object into a different position to compare it with a second similar shape — and object recognition — determining whether two complex objects are the same or different. Michael J.
Also collaborating on the study were William G. They used three of these objects — two of which were mirror images — for the mental rotation tasks and three which were slightly different but similar in appearance for the object recognition tasks.
Next, they assembled a group of 15 subjects and used functional Magnetic Resonance Imaging machine to measure activity levels in different parts of their brains. During the fMRI sessions, the researchers had the subjects perform two types of tasks using the objects. They displayed the objects in pairs on a screen and, in one case, they asked the subjects whether the two are identical or mirror images — a basic mental rotation task.
In the other case, they asked them whether the two objects were the same or different — a basic object recognition task. The objects were shown at different angles from each other on the horizontal, vertical and out-of-plane axes and the researchers measured the time it took the people to answer. When they examined the brain scans, the scientists found that the areas activated during the two tasks tended to lie on two different pathways in the visual system.
When asked questions about the identity of an object — for example, is it the same shape as a second object?
But when a person is asked where an object is located, the dorsal pathway, which lies in the parietal lobe, becomes active. The first place the researchers looked was the parietal lobe because previous studies had shown that it is involved in mental rotation tasks. They confirmed these observations and found that when the difference in orientation in the mental rotation tasks was large, the amount of parietal lobe activity was greater than when the difference was small.
In the object recognition tasks, however, the researchers saw a much different pattern. They did see some activity in the parietal region.
Surprisingly, however, the amount of activity in the parietal lobe decreased at larger orientation differences. In addition, they found that the brain area that did show an increase in activity with larger differences in orientation was in the ventral pathway. In Section II, the self-psychological approach is brought to bear on the clinical treatment of an adolescent girl, incest survivors, addictive personalities, patients exhibiting codependency, and a case of desomatization.

There was no basis for this train of thought, though his mind had so much needed to believe Once it had been believed that his fantasies were necessary.
Section III, on applied self psychology, contains chapters on the theory of creativity; subjectivism, relativism, and realism in psychoanalysis; and quantum physics and self psychology. The final section offers two critical review essays on major contributions to the self psychology literature by Wolf, by Bacal and Newman, and by Lichtenberg.
