RESEARCH STUDY 7.2: Dr. Parrett is a sports psychologist for a large Southern university. The provost and chancellor have asked

him to examine the relationship between athletic performance and academic stress at the university. For example, is it the case that the most talented athletes experience the greatest concern over their grades? The provost and chancellor have made it clear to Dr. Parrett that they want a large amount of external validity in the study. He has valid and reliable measures of both athletic performance and academic stress. He knows that he does not have the time or the money to study the entire population of interest.

Hello. This question is incomplete. The full question is:

"Dr. Parrett is a sports psychologist for a large Southern university. The provost and chancellor have asked him to examine the relationship between athletic performance and academic stress at the university. For example, is it the case that the most talented athletes experience the greatest concern over their grades? The provost and chancellor have made it clear to Dr. Parrett that they want a large amount of external validity in the study. He has valid and reliable measures of both athletic performance and academic stress. He knows that he does not have the time or the money to study the entire population of interest.

Imagine that Dr. Parrett wants to use a nonrepresentative sampling technique. Name the three types of nonprobability sampling and explain how each one could be used by Dr. Parrett."

Answer:

The four types of nonprobability sampling are convenience sampling, purposive sampling, quota sampling, and snowball sampling.

Explanation:

Convenience sampling: Allows a selection to be made of a small sample of the target population of the research. This sample is made up of individuals who are available and accessible to research and not through statistical criteria. Regarding the question above, Dr. Parrett can select the athletes he knows and who would like to participate in the research.

Purposive sampling: It allows the sample to be controlled whenever a certain manipulation is possible to generate expected and known results. In the case of the question above, Dr Parrett can search for specific athletes, with characteristics that will generate an expected result in the research.

Snowball sampling: Allows the individuals who make up the sample to invite other individuals to compose the sample, who in turn can invite other individuals. In the case of the question above, Dr. Parret can invite the athletes he wants and ask them to call friends to participate in the survey as well.

Sampling quota: Allows the individuals who will compose the sample to be selected due to their characteristics and qualities. Regarding the question above, Dr. Parrett could only summon athletes with high marks.

Steve learned how to play cribbage when he was 10. Now he is attempting to remember how to play it so he can teach Mary. Give an
Karo-lina-s [1.5K]

Answer:

Short-term memory: short-term memory is responsible for storing the information for a short time that we will not need in the future since it has as properties that its capacity is limited and for a short time. Likewise, short-term memory can only remember or retrieve the information of 7 elements with the variation of two parts already decreasing or increasing.

Long-term memory: this memory is responsible for storing unlimited information for a long time, long-term memory is what helps us to perform daily tasks and automatically since it is accountable for storing skills and facts when A job is done and retrieve those memories later.

Procedural Memory: this is responsible for storing all the steps or processes that we must perform to do a task since this memory is responsible for recovering all the necessary motor and executive memories.

Semantic Memory: semantic memory is responsible for storing all the conceptual or factual information of what we are learning; this memory is essential to help us understand the environment in which we live and people. Semantic memory helps us to think abstractly and to form the concepts necessary for language development.

Episodic Memory: this memory is responsible for storing and processing the information of memories lived during our lives, begins its development in childhood, and reaches its maximum development in adulthood. Episodic memory and semantic memory form declarative memory.

Explanation:

In Steven's case he wants to teach Mary to play Cribbage, which is a game that he learned at 10, so Steve tries to recover a memory so that in this situation the long-term memory that is responsible for storing the information for all these years, the episodic memory that has the function of storing all the resources. It also uses the procedural memory that is responsible for saving all the information of the processes such as playing cribbage, the semantic memory that is then responsible for storing all the concepts that Steve learns, or learned.

And finally, the short-term memory that has the first function because it was the one that Steven used to save the information first and then pass it to the long-term memory.

After doing the whole process of remembering, you can put your knowledge into practice in the cribbage to explain to Mary.

<em>I hope this information can help you.</em>

Alec has graduated from college and is moving to a large city to start a new job. Once he arrives, he plans to buy his first new
Taya2010 [7]

Answer:

Cold weather

Explanation:

The reason that Alec should limit his driving time/distance in all of the following areas or conditions except for cold weather is because of a concept called temperature inversion. Temperature inversion means that in winter season there is a warm layer of air trapped between two cold layers of air. This happens in winter as the air at altitude is always cold but now the surface temperature or air is also cold. Hence, the warm air above the surface and at lower altitude traps air pollutants contributing to smog occurrence. This is a natural phenomenon and therefore, Alec cannot reduce the chance that he will contribute to a major smog occurrence during cold weather by limiting his driving.

Vygotsky would say Latoya is "Using private speech to organize and regulate her thinking."

Vygotsky (1987) was the primary psychologist to report the significance of private speech. He considered private speech as the progress point amongst social and internal discourse, the moment being developed where dialect and thought join to constitute verbal reasoning.
