evaluate whether the evidence used to support this claim is sufficient.

teens have a reputation for making some not-so-smart decisions. researchers have blamed those poor decisions on the immaturity of a teen’s prefrontal cortex. that is the part of the brain involved in making plans and decisions. but scientists now find the answer may be simpler: the allure of rewards. rewards, even small ones, entice teens more than they do adults.
and, perhaps surprisingly, teens tend to continue doing things they once found rewarding, even after the actual payoff is long gone. both findings come from a new study by researchers at the university of iowa in iowa city.
psychologist zachary roper and his team worked with two groups of volunteers: 13- to 16-year olds and 20- to 35-year-old adults. each volunteer had to play a game of sorts. during a training phase, a computer displayed six circles, each a different color. the players had to find the red or green circle. these targets had either a horizontal or vertical line inside. the remaining circles had lines at other angles. when the participant found the correct target, they had to press one of two keys on a keyboard. one key would report they had found the vertical line. the other reported finding a horizontal line.
when a volunteer hit the right key, the screen flashed the amount of the reward they had earned. for some volunteers, green circles provided a large (10-cent) reward and red circles provided a small (2-cent) reward. for other volunteers, the amounts were reversed, with red circles worth more. all other colors had no reward.
by the end of this training, volunteers had learned the value of each color. but they weren’t aware that they had, notes iowa’s jatin vaidya. when the scientists asked the players about the value of red versus green circles, both teens and adults had no awareness that a circle’s color had any effect on how much they had earned during any given trial.
after this training ended, it was time to begin testing in earnest. the scientists informed the volunteers they had a new target. each had to report the orientation of the line inside a blue diamond. again, groups of six symbols appeared on a computer screen. only one was a diamond. the other five were still circles. in some trials, one of those circles was red or green. in other trials, there were no red or green circles.
the recruits were told to answer as quickly as possible. and for this phase of the experiment, no additional money would be earned.
the researchers now measured how long it took people to find the diamond and record their answers.
when no red or green circles were among the onscreen options, both adults and teens responded quickly. but when a red or green circle showed up, both groups initially took a bit longer. adults, though, quickly stopped paying attention to the colored circles. their response times sped up.
teens reacted differently. they took longer to respond whenever a red or green circle showed up. their response times never sped up. their attention still was drawn to the previously valued circles — even though the shapes no longer brought any reward. clearly, the red and green circles were distracting teens from their objective.
roper’s team reported the findings september 10 in psychological science.
“the study demonstrates that the attention of adolescents is especially drawn to rewarding information,” says brian anderson. a psychologist at johns hopkins university in baltimore, md., he was not involved with the study. these data may explain why teens engage in risky behavior, he says.
some behaviors, such as texting or using social media, trigger the brain’s reward system. once the teenage brain has linked a behavior to that reward, it continues to seek the reward again and again. that’s why teens are likely to opt for the reward of social media when they should be studying. or why they respond to texts while driving.
how can someone overcome their brain’s attempts to distract? vaidya suggests physically removing distractions whenever possible. shut down the phone when driving or disconnect from wi-fi while doing homework. when distractions are not readily available, it will be easier to focus attention on the things that matter most. like arriving home safely.
I guess the long term effects are the result of too much caffeine!
Hoping to fix "bad blood" was the reason the people involved with the study gave to the patients.
I got it right!
The answer is "community".
Biology is the investigation of life. Since life is such a wide point, researchers separate it into a few unique levels of association to make it less demanding to think about. These levels begin from the littlest unit of life and work up to the biggest and most general class.
A community comprises of all the distinctive species inside a specific territory. The number of inhabitants in lions in Kenya, in addition to the populaces of gazelles, giraffes, elephants, fertilizer creepy crawlies, and every single other specie here, mean a community.
The answer is A) It describes the result of a study that linked music education with improved reading scores. The reason being that the main focus of the article is to highlight the improvement the music students showed against those students that did not take part in this special program.
As stated in the following paragraph : ''The study concluded that there were signifcant improvements in reading scores for the children who attended music clases regularly (...)'' the evidence that was provided by the team of researchers was the improvement in reading scores.
Hope this helps!
The correct answer is B) The people involved with the study told the men that they were being treated for "bad blood."
The option that would be would be an acceptable paraphrase of the information is the following: The people involved with the study told the men that they were being treated for "bad blood."
The excerpt is referring to the unethical study conducted by the United States Public Service between 1932 and 1972. The name of the study was the Tuskegee Study of Untreated Syphilis in the Black Men. The cruelty of the study was that none of the 399 men that had syphilis were treated to cure the disease; they never received the penicillin necessary to be cured.
The correct answer is C. The hypothesis of the study.
In research, informed consent implies the researcher needs to inform potential participants about different aspects of the research and their participation, in this way they can decide whether or not to participate. This includes explaining potential participants about possible harms or benefits, procedures they will be involved in, among others. However, the researcher is not forced to inform them about the hypothesis of the study as this might influence participants' answers or performance and thus make the research invalid.
This is an example of a double-blind type study.
Neither the researchers nor the participants know whether they are receiving caffeine or not. Thus there are no behaviors that people might observe due to bias. If the researcher was convinced that the caffeine tablets would increase excitability, and knew who was taking actual caffeine, then this bias could result in incorrect assessments of behavior.
If the subjects knew that they were taking placebos for example, then they might suppress all evidence of excitability, even in the face of events that might be expected to cause a normal excited response.
Therefore, the double-blind type of study is expected to produce the least biased behaviors and observations.
