The Availability Heuristic

The Availability Heuristic

A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Drug Dependence

Drug Dependence

Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Self-Discrepancy Theory

Self-Discrepancy Theory

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

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 the way you...

Motivational Bias

Motivational 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,...

Hindsight Biases

Hindsight Biases

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?

Area of Science:

Neuroscience
Molecular Biology
Behavioral Science

Background:

Goal-directed actions are controlled by outcome value, while habits are less dependent on outcome changes.
Habit formation can be induced by extended training, specific reinforcement schedules, or substance abuse.
While brain circuits for habit formation are known, molecular mechanisms remain unclear.

Purpose of the Study:

To investigate the molecular mechanisms underlying habit formation.
To establish behavioral procedures for studying habit formation in mice.

Main Methods:

Development of novel behavioral procedures for habit formation in mice.
Application of genetic and pharmacological tools to investigate molecular pathways.
Analysis of endocannabinoid signaling's role in habit learning.

Main Results:

Endocannabinoid signaling was identified as critical for habit formation.
The study established a framework for molecular investigation of habit formation.
Behavioral procedures allowed for detailed study of habit acquisition.

Conclusions:

Endocannabinoid signaling plays a vital role in the molecular underpinnings of habit formation.
The developed methods facilitate further research into the neurobiology of habits.
Understanding these mechanisms is crucial for addressing compulsive behaviors in addiction.
