1.) Infants can distinguish between different caresses.
2.) 16 subjects
3.) No, it does not say that there was a control group.
4.) It does not specify.
5.) They had the mothers hold their babies, and then stroke them with a soft brush. They did that at a rate of 20 cm per second and at a rate of 3 cm per second. They learned that the slower stroke gave the infants a faster blood flow.
6.) The slower strokes gave the infants more blood flow which showed they were more stimulated. The slow stroke is the more "social" and "caring" stroke.
7.) Yes, they acted the way the experimenters thought they would.

1.) Researchers studied how risky behavior can impact PTSD symptoms.
2.) They assessed more than 200 veterans.
3.) It does not say if there was a control group or not.
4.) They had to be veterans. Other than that, I don't believe there were any other requirements.
5.) They tested the veterans and noted if they had PTSD or not. They then asked them about their risky behaviors and their PTSD symptoms. Four years later, they re-tested the same veterans and asked about their risky behavior and they asked about their symptoms.
6.) In the time between the two tests, 82% of the subjects had a potentially traumatic event because of a risky behavior.
7.) Yes, they did.

1.) The researchers studied how alcoholic dependence impacts sleep disorders.
2.) They had 135 subjects.
3.) They did not say there was a control group.
4.) They had to be human subjects that spoke English.
5.) They didn't really experiment, they actually looked at data bases from previous experiments.
6.) They found there was a bidirectional in nature. Meaning that AD impacted insomnia, short sleep duration, the circadian rhythm, and other sleep disorders.
7.) Yes, the subjects had the expected reaction.

1.) The researchers studied how poor episodic memory, a common feature of schizophrenia, which leads to poor social skills.
2.) It doesn't say how many people exactly, but there were three groups.
3.) There was a control group and they were not schizophrenic.
4.) It did not specify how the subjects were chosen.
5.) The subjects watched 24 shorts films of average social situations, and were then shown 24 pictures of people who were not in the films, and 24 of people who were in the films. They were asked to tell whether or not they were in the films. Most people did well with that. The trouble came when they had to tell what film or situation that person was in.
6.) People with no schizophrenia did fairly well with both of the tests. The people with chronic schizophrenia had trouble putting faces with the situations. Also, impaired episodic memory is an early indication of schizophrenia.
7.) Yes, the subjects reacted as the researchers had expected.
