Framing Effects03:26

Framing Effects

7.9K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

404
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Relative Risk01:12

Relative Risk

2.0K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Attitudes01:54

Attitudes

32.7K
Attitude is our evaluation of a person, an idea, or an object. We have attitudes for many things ranging from products that we might pick up in the supermarket to people around the world to political policies. Typically, attitudes are favorable or unfavorable: positive or negative (Eagly & Chaiken, 1993). And, they have three components: an affective component (feelings), a behavioral component (the effect of the attitude on behavior), and a cognitive component (belief and knowledge;...

Confirmation Biases01:31

Confirmation Biases

7.6K
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?

Motivational Bias01:25

Motivational Bias

309
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...

Summary
This summary is machine-generated.

Post-choice outcome feedback consistently increases risk-taking behavior, but not decision accuracy. This effect stems from attitudinal shifts, like curiosity and anticipated regret, rather than learning from experienced outcomes.

Area of Science:

  • Cognitive psychology
  • Behavioral economics
  • Neuroscience

Background:

  • Normative decision theory assumes feedback doesn't alter preferences for fully described lotteries.
  • Empirical evidence shows feedback impacts risk-taking, but consensus on mechanisms is lacking.

Purpose of the Study:

  • To disentangle the learning and attitudinal hypotheses of feedback effects on decision-making under risk.
  • To investigate the cognitive mechanisms driving feedback-induced changes in risk-taking.

Main Methods:

  • Conducted seven behavioral experiments involving decision-making under risk with varying feedback conditions.
  • Employed fine-grained temporal analyses to differentiate between pre- and post-experience effects.
  • Examined the influence of partial versus complete feedback.

Main Results:

  • Feedback consistently increased risk-taking but did not improve decision maximization.
  • Temporal analyses indicated feedback's influence precedes outcome experience, challenging the learning hypothesis.
  • Partial feedback increased risk-taking due to curiosity; complete feedback increased it due to anticipated regret.

Conclusions:

  • Feedback biases decision-making primarily through attitudinal mechanisms, not learning.
  • Curiosity and anticipated regret are key attitudinal drivers of increased risk-taking post-feedback.
  • Understanding these attitudinal shifts is crucial for explaining decision-making under risk.
