Dr. LaGuardia is a cognitive neuroscientist who is interested in the effect of brain concussions on the ability to recognize faces. He conducts a quasi-experimental study in which he examines football players before and after the regular season, using the Benton Facial Recognition Test (a published, widely used measure of one’s ability to recognize faces) to compare those who received concussions to those who did not. He finds that players who had concussions during the regular season performed worse on the Benton Facial Recognition Test than did players who did not experience concussions. Which of the following makes Dr. LaGuardia’s quasi-experimental study different from a correlational study?
A. He used a validated measure of the dependent variable.
B. He was able to confirm the occurrence of a concussion rather than relying on self-report.
C. He used a naturally occurring comparison group (i.e. players who did not suffer a concussion).
D. He used memebers of a real sports team rather than members of the general population.

Answers

Answer 1

Answer:

D. He used members of a real sports team rather than members of the general population.

Explanation:

Quasi-experimental study: In research methods, the term "quasi-experimental study" is described as a study that encompasses manipulation of the "independent variable" in the absence of a random assignment of subjects or participants to orders of conditions or different conditions.

Correlational study: In statistics, the term "correlational study" is described as one of the different types of study designs in which research or an investigator tends to comprehend the type of relationship that a naturally occurring variable possesses with one another.

In the question above, the correct answer is option D.

Answer 2

The option that makes Dr. LaGuardia's quasi-experimental study different from a correlational study is: He used a naturally occurring comparison group (i.e., players who did not suffer a concussion). The correct option is C.

In a correlational study, researchers observe and analyze the relationship between variables without manipulating them. However, in Dr. LaGuardia's quasi-experimental study, he specifically examines the effect of concussions on the ability to recognize faces by comparing football players before and after the regular season. By using a naturally occurring comparison group of players who did not suffer a concussion, he is able to compare the performance of those with concussions to those without.

Thus, the ideal selection is option C.

Answers

Germophobic or WEIRDOITUS

Explanation:

Final answer:

Based on Lynn's excessive handwashing and fear of contamination, she likely has Obsessive-Compulsive Disorder (OCD). This mental health condition involves repetitive unwanted thoughts and behaviors. Treatment often involves Cognitive Behavioral Therapy.

Explanation:

Given the description of Lynn's behaviors and concerns, it strongly suggests that she might have Obsessive-Compulsive Disorder (OCD). OCD is a mental health condition characterized by unwanted repetitive thoughts (obsessions) and behaviors (compulsions). Lynn washes her hands excessively (compulsion) because she fears contamination (obsession). Her relief after washing hands is temporary and the cycle repeats, which is typical of OCD. To help Lynn, professional help from a psychologist or psychiatrist would be beneficial. Cognitive Behavioral Therapy, especially a type of it known as Exposure and Response Prevention, is often effective at reducing OCD symptoms.

Lynn's excessive hand washing, to the point of causing cracked and bleeding hands, is indicative of a condition called obsessive-compulsive disorder (OCD). OCD is an anxiety disorder characterized by recurrent, unwanted thoughts (obsessions) and repetitive behaviors (compulsions). In this case, Lynn's compulsive hand washing is driven by her fear of contamination.

By engaging in the act of hand washing, Lynn experiences momentary relief from her contamination concerns. This relief reinforces the behavior, leading to a cycle of continued hand washing. It is important for Lynn to seek professional help, such as therapy or medication, to manage her OCD symptoms and improve her quality of life.

Answer:

d. seats in the legislature are allocated to political parties based on their share of the total vote cast in the election.

Explanation:

In a proportional representation electoral system seats in the legislature are allocated to political parties based on their share of the total vote cast in the election.

In this system each political party gets a seat allocation based on its performance in the election.

For instance, if the candidates of a party win 50% of the vote in a 10 member district, they receive five of the ten seats — or 50% of the seats. If another party wins 30% of the vote, they get three seats, and so on.

The seats in the legislature are then allocated to the political parties based on their shares of the total vote cast in the election. This the option D is correct.

A

C
D

Answers

The United States has a mixed market economy, which is more market-oriented but still includes some government intervention. Option c) is correct.

The United States has a mixed market economy. This means that it combines elements of command and market systems, although it is positioned toward the market-oriented end of the spectrum. The U.S. economy features a significant degree of private ownership and market-based decision-making, but it also includes government involvement in economic decisions, which is characteristic of a mixed market system. In contrast, many European and Latin American countries have a greater degree of government involvement in their primarily market-oriented economies. Meanwhile, countries like China and Russia, despite moving towards more market-oriented systems in recent decades, are still closer to the command economy end of the spectrum.

A waste company has been dumping untreated sewage into the river next to the house. They have recently been found guilty because of the effect the pollution has had on the plants and animals living there. What effect has the raw sewage had on the animals that live in the river?

Answers

Final answer:

The effects of dumping untreated sewage into a river include depletion of oxygen, spread of disease, disruption of aquatic ecosystems, and accumulation of toxins in the food chain, posing risks to the health of both aquatic and land animals, as well as humans.

Explanation:

The dumping of untreated sewage by a waste company into a river can have devastating effects on the aquatic ecosystem. This form of water pollution introduces harmful pathogens, depletes oxygen levels, and provides excessive nutrients which can lead to eutrophication. The latter creates a bloom of algae that blocks sunlight and further reduces oxygen available to aquatic animals, causing massive die-offs and disruption of the food chain. Moreover, toxic substances like heavy metals and chemicals can accumulate in the bodies of aquatic organisms, a process known as bioaccumulation, which is harmful to the animals consuming the contaminated water and to the predators up the food chain, including humans.

Water pollution not only affects the quality of aquatic life but also the health of land animals and humans who rely on the river for their water supply. Untreated sewage contributes to the spread of disease and can contaminate drinking water sources, posing significant health risks. Implementing proper wastewater treatment processes is crucial to preventing such environmental and health hazards.

Men misattributed their fear as sexual attraction.

Explanation:

Misattribution of arousal is a term in psychology which describes the process whereby people make a mistake in assuming what is causing them to feel aroused.

do you think classification of economic activities into primary secondary an tertiary is usefull? explain how

Answers

Answer: YES, the classification of economic activities into primary, secondary and tertiary is useful.

Explanation: Economic activities can be defined as any activity that involves the production, distribution, and consumption of goods and services.

They are classified into;

Raw Materials (Primary Sector) Manufacturing and Industry (Secondary Sector) Service Sector (Tertiary Sector) Knowledge Sector (Quarternary Sector)

This classification is especially important because it it makes every sector distinct; this classification can be used for statistical purposes; for assigning taxes based on the sector they are in; and also important in the measure of the economy's gdp.

Answer: Yes, classification of economic activities into the primary, secondary and tertiary sector is vital as it helps in showing the relative importance in the growth in the gross domestic product of the economy.

Explanation:

The three-sector model in economics divides the economies into three sectors which are the primary sector that deals with the extraction of raw materials, the secondary sector that deals with manufacturing and the tertiary sector that deals with services.

In highly developed countries that has a high income, the tertiary sector dominates the economy and makes up the largest in the total output of the economy. Countries that are in the early state of development are usually in the primary sector as they deal with farming and fishing activities.

Classification of the sector is important as it shows the growth in the gross domestic product of the economy.and can be used to evaluate how developed an economy is.

Classifying in such a way helps in calculating how much goods and services are produced and how many people work in each sector
