Hindsight Biases01:12

Hindsight Biases

3.4K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Expected Value01:15

Expected Value

3.9K
The expected value is known as the "long-term" average or mean. This means that over the long term of experimenting over and over, you would expect this average. The expected average is represented by the symbol μ. It is calculated as follows:

Decision Making: P-value Method

5.3K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Confirmation Biases01:31

Confirmation Biases

5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Prediction Intervals01:03

Prediction Intervals

2.3K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Stereotype Threat and Self-fulfilling Prophecies02:09

Stereotype Threat and Self-fulfilling Prophecies

37.6K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Summary
This summary is machine-generated.

Reinforcement learning concepts, like prediction errors, can explain subjective feelings and value. Researchers should test these concepts for affect research, not assume they apply directly.

Area of Science:

  • Cognitive Science
  • Neuroscience
  • Psychology

Background:

  • Reinforcement learning (RL) concepts are increasingly applied to the study of affect.
  • Reward prediction errors are foundational in RL research on adaptive behavior.
  • Historically, RL research focused on observable rewards, with less attention to subjective feelings.

Purpose of the Study:

  • To explore the application of RL concepts to affect.
  • To investigate the explanatory power of affect-based prediction errors.
  • To propose RL concepts for elucidating subjective value.

Main Methods:

  • Review and conceptual analysis of reinforcement learning principles applied to affect.
  • Examination of existing research on reward prediction errors in humans and animals.
  • Discussion of the shift towards affectivism in psychological research.

Main Results:

  • Affective prediction errors (differences between expected and experienced feelings) offer explanatory power beyond observable rewards.
  • Subjective value can be elucidated by applying RL concepts to affect.
  • Human ability to report expected and experienced affect is a key factor.

Conclusions:

  • Applying RL concepts to affect shows promise for understanding subjective value.
  • Scientists should critically test RL concepts for their applicability to affect.
  • Future research should focus on the unique aspects of affective prediction errors.
