Summary
Human decision-making involves both internal preferences and external rewards. This study shows that personal preferences influence choices even when external factors are primary, and these preferences persist afterward.
Area of Science:
- Cognitive Neuroscience
- Behavioral Economics
Background:
- Decision-making is fundamental to human behavior.
- Processes are categorized as internally guided (IDM) or externally guided (EDM).
- The interplay between IDM and EDM in real-world scenarios is not fully understood.
Purpose of the Study:
- To investigate the relationship between internally guided decision-making (IDM) and externally guided decision-making (EDM).
- To determine how individual preferences (IDM) influence choices driven by external rewards (EDM).
Main Methods:
- Participants completed a preference judgment task (IDM) followed by a gambling task (EDM).
- Computational modeling was employed to analyze choice behavior.
- Subjective preference evaluations were assessed post-task.
Main Results:
- Strong individual preferences (IDM) significantly impacted initial choices in the externally guided decision-making (EDM) task.
- Preferences established in IDM were maintained even when associated stimuli were devalued in the EDM context.
- Internal and external criteria for value were found to be distinct.
Conclusions:
- Internal value criteria, such as personal preferences, exert influence over externally guided decision-making processes.
- Despite potential conflicts in value perception between internal and external criteria, established preferences demonstrate resilience.
- This research highlights the distinct yet interactive nature of internal and external influences on human decision-making.

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

01:05Instinctive Drift
207
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

01:20Decision Making
106
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

01:14Fundamental Attribution Error
12.8K
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...

01:08Timing and Consequences on Behavior

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...
