Explanation:
The hindisght bias occurs when a person believes an event was more predictable than it really was. For this reason, it is often referred to as the "knew-it-all-along bias". This phenomenon causes memory distorsion, and in turn can also explain overconfidence about predicting future events.
Answer:
A Differential Reinforcement Of Low Rates Of Behavior
Explanation:
Differential reinforcement of low rates of behavior (DRL) is described as a schedule in which a minimum amount of time must pass between responses in order for a reinforcement to occur. For instance, spaced-responding DRL, the interval duration may be increased to further reduce behavior. This was described by Ferster and Skinner in the year 1957
Differential reinforcement of low rates of responding (DRL) can also be said to be a technique in which a positive reinforcer is given or delivered at the end of a specific interval if a target behavior has occurred at a criterion rate. It is usually used in educational settings to manage classroom behaviors.
Maria being praised by her teacher whenever she asks for permission to speak at certain intervals is a typical example of Differential reinforcement of low rates of responding (DRL).
Answer: The correct answer is: "As of January 2015, the NIH expects investigators to obtain the informed (valid) consent of research participants in NIH - funded genetic research for broad research use of data and data sharing, even if the cell lines or specimens are de-identified."
Explanation:
De-identification refers to the process of keep hidden someone's personal information. In general, people who participate in a research want their personal information (name, ID, address, phone number, date of birth) maintain anonymous. For that reason, the NIH expects investigators to obtain the informed (valid) consent of research participants even if they had decided to keep their samples as de-identified.
A simple reason in for the increase of polls is its cheap availability
and use of social media, both of these factors when interconnected can make it
really easy for anyone with the right approach to create a poll. Those people
who are in the policy making business also use the medium to get the latest of
public opinions about certain issues which may help them create a relevant
policy.
There is just one danger as I see it, that when it comes to
politics the politicians focus more on getting votes by spreading and creating
biased polls which help mold the public opinion to a certain extent.
