Dr. DeLoss is interested in whether training can improve vision in older adults. He first measured visual acuity (clarity of vis

ion) in a sample of 100 people. He then had a group of 50 participants completed a 15 minute training task once a day for one month. The other 50 people did nothing different in their routine. At the end of the month he had both groups participate in another visual acuity test to measure any changes in vision. Identify the independent and dependent variables.

Answer:

complete task, visual acuity

Explanation:

The independent variable is a naturally occurring or somewhat random variable that the researcher has no control over

The dependent variable on the other hand is variable that is caused or influenced by the independent variable.

From the above, Dr. Deloss's independent variable is "complete task" and his dependent variable is "visual acuity" since it is influenced by the tasks completed by participants.

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>

zaharov [31]

The correct answer is True

According to psychology, perception consists of an organization and interpretation of the stimuli that were received by the senses and that makes it possible to identify certain objects and events.

Perception has two stages, the sensorial and the intellectual. The two complement each other, because sensations do not provide a real view of the world, and must be worked on by the intellect

The Davis family grows organic vegetables to sell at a local farmer’s market. Which are factors that directly affect their profi
statuscvo [17]

The factors that directly affect the Davis family's profit for growing organiz vegetables to sell are the following two:

- <u>A rise in demand for organic produce</u>: when the demands for a product rises, that means that the selling price for that product will rise as well. This is because of the supply and demand correlation. When the demand grows, the supply lowers, so the products can sell for higher price since there are fewer of them.

- <u>An increase in the cost of farm equipment</u>: if they have to spend more money in equipment, their final profit decreases, that's because they have to spend more money to grow their produce, but the price when they sell it remains the same, unless they rise it. It directly affects the profit.

" A change in the market price for non-organic fruit" can't be considered to DIRECTLY affect their profit, but we could consider it to INDIRECTLY affect it. For example if the price increases, then more people might start buying organic produce, because they might find that the price difference decreases and the benefits of eating organic produce is higher. But this isn't a sure thing, that's why it doesn't apply.

"A sale on organic meats at the market" shouldn't be considered to directly affect the Davis' profit because buying meat doesn't have a correlation to affecting organic produce's profit.

-"An increase in customers at the market" it's not a direct correlation to affecting the profit, so it's ruled out.
