The two different types of twins are identical and fraternal twins. Identical twins are formed by a single zygote cell splitting into to two cells and the now two cells form as two different people. Since, identical twins were formed from the same cell their genetic make-up are the same, which makes them look alike. On the other hand, fraternal twins are formed when a mother releases two eggs during her cycle, the separate eggs are fertilized by different sperm cells, and each develop into their own person. So, fraternal twins share only 50 % of their DNA with twin just like another brother or sister. Twin studies are studies that compare concordance rates, which are percentages of shared traits or disorders. Identical twins are found to have…show more content… Hypnosis is an alternate state of consciousness, which is described by attention, deep relaxation, and heightened susceptibility to suggestion. One situation where hypnosis worked was when a hypnotist made a person relive a past event called hypnotic age regression. Also, a hypnotist made a person lose feeling or responsiveness to pain. This is called hypnotic analgesia (p. 152). Then there is the situation when a hypnotist posthypnotic suggestion, which is where a hypnotist plants an idea in people’s minds and after they come out of hypnosis they respond to those ideas in a certain way. Three theories of hypnosis, include the role-playing model, trance state, and neo-dissociation theory. The role-playing model suggest that hypnosis is a social interaction between the hypnotist and the subject, in which the subject faithfully follows the hypnotist directions. This relates to hypnotic suggestion, because the more willing a person is to participate in hypnosis relates to how open they are to suggestion. The next theory is the trance state, which suggest that hypnosis is an alternate state of consciousness, which heightens a person suggestibility. This theory relates to hypnotic age regression, because when someone goes back into a past memory, they are accessing a part of their brain that is unrelated to consciousness or in other words an alternate state of awareness. The third theory, neo-dissociation, suggest that hypnosis is a special state of consciousness, which…show more content… The issue between whether if a person’s behavior is governed by nature, genetics, or nurture, environmental and cultural. The argument between nature and nurture is focused more of the relative contributions of nature and nurture to particular behaviors rather than nature and nurture. Most of psychologist today believed that it’s a little bit of both, nature and nurture, that help form a person’s behavioral pattern (p. 78). A person’s genetics in some way influence our behavior including traits like shyness or sociability. Genetics also comes into play when you consider psychological disorders, like anxiety disorders or alcohol and drug abuse disorders. However, it is also true that nurture plays a role in forming a person’s behavioral personality. If a child’s parents are overprotective of a child, who is shy, they are enforcing the shyness behavior onto that child. It’s the same for parents who want their child to be social. Whatever behavior the parents enforce plays a role in how the child’s behavior develops. Also, if a child is exposed to an environment where drugs and alcohol are abuse, they in turn are more likely to abuse drugs and alcohol as well. A person cannot answer whether it’s nature or nurture, because both influence a person’s behavior (p.
