A researcher is interested in how heart rate and blood pressure are affected by viewing a violent film sequence as opposed to a non-violent film. He conducts an experiment to investigate the relationship.
a) Heart rate and blood pressure are the __________________ variables.
b) The type of film watched is the _________________________ variable.
c) The group that views a violent film is the ___________________ group.
d) The group that watches a nonviolent film is the ______________ group.

Answers

Answer 1

Answer:

The answers are:

a. dependent

b. independent

c. test

d. control

Explanation:

In scientific research, investigations are done to study whether certain factors change while changing others, and the following terms are associated with  scientific research:

a. dependent variable: These are factors or outcomes that are being investigated in a research experiment, and they are not under the direct control of the researcher. They are factors that vary as a result of other changes made in the process. In our example, the heart rate and blood pressure are proposed to vary with the type of film watched hence these factors are dependent variables.

b. independent variable: Independent variables are variables that are under the direct manipulation of the researcher, and the predetermined variation of these variables cause certain effects on the dependent variables. In our example, the type of film is the independent variable, because the researcher has complete control over the type of film watched.

c. Test group: These are the group of participants/individuals in research, who will potentially be affected by the change in the dependent variable to cause an effect that deviates from the normal. In our example, the group that views the violent film is the test group, because there is a tendency that they might have altered heart rate and blood pressure as a result of the type of film viewed.

d. control group: The control group is the group of individuals whose effects at the end of the experiments will serve as baseline effects, to serve as a means of measuring the magnitude of variation in the test group. These groups serve to eliminate any other effects that might cause similar changes as the factor being investigated in all test participants.

In the context of the types of evidence described by Cook and Campbell (1979), in this scenario, Sam fails to :

B. account for temporal precedence

C. eliminate the influence of facilitated communication

Explanation:

It might very well be that Sam is right, and that Jill did fall sick due to the food she had from that particular food truck. However, at no moment did Sam consider other alternatives. To him, it is as if not other explanation were possible, only that one. There may be several reasons why Jill fell sick. The appropriate thing to be done would be for Sam to consider these other options and then work to eliminate them.

When justices on the Supreme Court discover conflicts in the reasoning that supports their decisions, they must sometimes a. Use neither reason.b. Draft a new reason to support their decision.c. Use both reasons.d. Choose one rationale over another.

Answers

Answer:

d. Choose one rationale over another.

Explanation:

Due to the fact that, judicial decisions are also affected by various internal and external factors, such as legal, personal, ideological, and political influences. In order to make what appears to be non-bias decision, Supreme Court rulings have to keep up with the changing times.

Hence, when justices on the Supreme Court discover conflicts in the reasoning that supports their decisions, they must sometimes "choose one rationale over another." That is, they must sometimes choose reason they believe is more logical and understanding, and support their decision better.

In classic research, Dweck (1975) found that boys tend to attribute their poor performance in math to _____ factors, whereas girls tend to attribute their poor performance in math to _____ factors.

Answers

Answer:

In classic research, Dweck (1975) found that boys tend to attribute their poor performance in math to unstable internal factors, whereas girls tend to attribute their poor performance in math to stable internal factors.

Explanation:

Here, we are talking about motives related to attribution. Notice that Dweck found that boys attribute their success in math to unstable internal factors, and girls to stable internal factors.

External and internal are related to the locus of the attribution, the "location" of the cause of success or failure. For instance, an external attribution may be the fact that the test was easy. An internal one may be our own ability in math.

Unstable and stable are related to the stability of the attribution. For instance, cramming for the exam is an unstable attribution, since the effort we put into studying may vary each time. Ability, on the other hand, is a stable one, since it lasts and has consistency.

What is an antisocial personality disorder?

A person who continuously disregards right and wrong and the rights and sentiments of others is said to have an antisocial personality disorder, often known as sociopathy. Antisocial personalities have the propensity to manipulate, provoke, or treat people cruelly or with callous indifference. They don't display any regret or guilt for their actions.

People with antisocial personality disorder frequently break the law and turn into criminals. They might be dishonest, act violently or rashly, and struggle with drug and alcohol abuse. Due to these traits, individuals with this disorder frequently fail to fulfill obligations to their families, employers, or educational institutions.

There is no surefire technique to stop people at risk from acquiring antisocial personality disorder. Parents, teachers, and pediatricians may be able to see early warning signals since antisocial conduct is regarded to have its origins in childhood. In order to provide early intervention, it may be helpful to try to identify individuals who are most at risk, such as kids who exhibit conduct disorder symptoms.

After Hunter has a terrible fight with his boyfriend, he returns home and yells at his dog for sleeping on the sofa—even though the dog is usually allowed to sleep on the furniture. Hunter's process of venting his anger on a safer target is an example of __________.

Answers

Answer:

Hunter's process of venting his anger on a safer target is an example of displacement.

Explanation:

Displacement is a defense mechanism that consists of changing an object that produces an unacceptable emotional reaction, for another, without there being a link between both elements, that is, the displacement refers to the redirection of an impulse (usually an aggression) towards a person or an object. We "displace"  certain emotions associated with an object, to another object that we attack or avoid, because it does not provide as much fear as the first.

Answer:

Hunter's process of venting his anger on a safer target is an example of displaced aggression.

Explanation:

If Hunter had yelled at his boyfriend, he would have displayed direct aggression. However, what he did is an example of displaced aggression. Displaced aggression happens when an aggressive behavior is directed to someone who is not the original source of frustration or provocation. Usually, people display displaced aggression when they cannot respond to the original source for some reason - maybe because it is impossible, may because it would have grave consequences. That is precisely what Hunter did. He vented his anger on a safer target, since he knows the dog will not retaliate.
