Summary
Response errors trigger defensive motivational responses. The error-related negativity (ERN) brain signal predicts the intensity of this defensive reaction, highlighting its role in processing negative feedback.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Affective Science
Background:
- The error-related negativity (ERN) is a neural signal linked to error detection.
- The anterior cingulate cortex generates the ERN, involved in cognitive and emotional processing.
- The ERN's magnitude is influenced by affective and motivational factors.
Purpose of the Study:
- To investigate if errors prime defensive motivational responses.
- To determine if the ERN predicts the magnitude of defensive reactivity post-error.
Main Methods:
- Measured event-related potentials (ERPs) including the ERN.
- Assessed defensive startle responses following correct and incorrect responses.
- Correlated ERN magnitude with startle response potentiation.
Main Results:
- Defensive startle responses were significantly larger after errors compared to correct responses.
- The magnitude of the ERN predicted the degree of startle potentiation after errors.
- Error commission activates defensive motivational systems.
Conclusions:
- Response errors prime defensive motivation.
- The ERN serves as a predictor of individual differences in aversive responses to errors.
- This suggests the ERN reflects motivational aspects of error processing.

01:12Types of Errors: Detection and Minimization
Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.

01:14Avoidance Learning and Learned Helplessness
Avoidance learning and learned helplessness are critical concepts in understanding behavioral responses to negative stimuli.
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...

01:14Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
01:27Punishment
Negative reinforcement and punishment are often confused but serve distinct functions in behavior modification. Reinforcement, whether positive or negative, increases the likelihood of a desired behavior, while punishment decreases it.
Punishment can be positive or negative. Positive punishment involves adding an undesirable stimulus, such as scolding, to decrease a behavior. Negative punishment involves removing a desirable stimulus, such as taking away a favorite toy, to decrease behavior.

01:24Rational Emotive Behavior Therapy
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert Ellis's...
01:25Motivational Bias
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,...
