If one identical twin is diagnosed as schizophrenic is there a high probability that the other twin will also have a mental disturbance?
Most of this information is from a website (linked below) and a book that I had at home on psychology. The book details are listed below aswell.
According to the genetic model, there is evidence to suggest that there is a hereditary element to schizophrenia/panic disorders. If an identical twin has schizophrenia or rather displays the symptoms thereof, it is very likely that the other twin can also display the same symptoms.
Schizophrenia is also often mistaken as depression and therefore incorrectly treated. In order to diagnose schizophrenia and or other mental disorders etc. clinicians can use what is called the DSM-IV (Diagnostic and Statistical Manual, and IV being the roman numerals for the number 4). Although I would like to mention here that this is a western scale and might not be able to accurately diagnose a person from a non-western country.

What do you call the tendency to respond to a stimulus that is similar but not identical to a conditioned stimulus?
Generalization is the tendency to respond to a stimulus that is similar but not identical to a conditioned stimulus.
Responding to stimuli that are similar-but not identical-to a conditioned stimulus is call?
Responding to similar stimuli is known as generalization in classical conditioning. This occurs when an organism responds to a stimulus that is similar, but not identical, to the original conditioned stimulus that was paired with an unconditioned stimulus.
Which research method allows researchers to most easily isolate the effect of both genetics and experience in a specific traits?
Twin studies, especially using identical twins raised in different environments, allow researchers to isolate the effects of genetics and experience on specific traits. By comparing identical twins who share all their genes but differ in their environments, researchers can attribute any differences in traits to genetic factors.
Which type of study provides the clearest way to address the nature-nurture question?
Twin studies, particularly those involving identical twins raised apart, provide a clear way to address the nature-nurture question by allowing researchers to compare the influence of genes (nature) versus environment (nurture) on a particular trait or behavior. By comparing the similarities between genetically identical twins raised in different environments, researchers can tease apart the contributions of genetics and environment.
How does heredity influence personality?
Determining the amount of genetic influence that contributes to the makeup of personality has proved to be a difficult task. However, in studying both fraternal and identical twins, we're able to gain some insight into this mystery. After a series of tests, studies have shown that identical adult twins were more likely to answer questions in the same way than fraternal twins were. In subsequent studies, identical twins who were separated for long periods of time compared to those who weren't separated continued to exhibit the same level of personality traits.
If one identical twin is diagnosed as schizophrenic there is a high probability that the other twin will also have this mental disturbance?
Yes, the development of schizophrenia has a genetic component.
What if one identical twin is diagnosed as schizophrenic there is a high probability that the other twin will also have this mental disturbance?
Identical twins share 100% of their genetic material, so if one twin has schizophrenia, the other twin has a high likelihood of developing it due to genetic predisposition. However, environmental factors also play a role in the development of schizophrenia, so it is not guaranteed that both twins will develop the disorder.
If the probability of getting identical is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen at random will not be a twin?
1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)
What age group of people are affected by schizophrenia most?
it is sometimes caused by head trauma, A number of reasons. Genetics is part of it. I have a friend who's schizophrenic and so is his dad, but they've got it under control. Like the person above posted trauma can cause it, but not just physical trauma, emotional trauma too. I know another guy who got it after a period of homelessness.
What is the probability of getting 4 of a kind if 5 identical dice are tossed simulataneously?
If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032If they are fair dice, the probability is 0.0032
If the probability of getting identical twins is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen will be a twin?
P(twin)=P(identical)+P(fraternal) P(twin)=0.004 +0.023 P(twin)=0.027 [That's 27 out of 1,000 cases, or 54 persons out of 1027.]
What is the probability of having twins if your husband is a twin?
Identical twins happen by chance only; 4 per 1000 births or 0.004 probability. Fraternal twin probability is increased only if it is on the mother's side; so this does you affect your circumstance (from what you have stated). The chance of fraternal twins is 1 in 60 or 0.017. So, your probability of identical twins is 0.004 and fraternal twins is 0.017 (BTW, I have triplets).
What is the probability of a head coming up on the fourth toss?
If you are talking about the toss of a coin, the probability for a head coming up on the fourth toss is identical to the probability of a head coming up on the first toss, or the 17th or the 9,437th: Exactly 50/50.
8 identical balls are placed at random in three bags. what is the probability that the first bag will contain 3 balls?
The probability that it contains exactly 3 balls is 6/45 = 0.133... recurring.
What are the chances of identical twins having twins themselves?
Women who are themselves fraternal twins have a 10% chance of producing twins, identical twin women have only a 0.6% probability of having a twin birth.
What is the probability of getting four heads when flipping four identical coins at once?
The probability is 2/4 or 4/8 or 1/2. The reason is that if you have 4 identical coins and you flip all of them at once you have half a chance because you could either get all heads, all tails, or a combination.
Two identical freight cars roll without friction towards each other on a level track?
The probability of them crashing is 1.
