Reason and Intuition01:37

Reason and Intuition

7.3K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Substance Use Disorders Affecting Sleep

342
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Self-Presentation: Self-Monitoring and Self-Handicapping

43.4K
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...

Causes of Social Behavior II: Cognitive Processes

160
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

Cognitive Dissonance

36.7K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

CNS Depressants: Alcohol and Nicotine

935
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Summary
This summary is machine-generated.

Heavy episodic drinking (HED) in university students is often driven by automatic habits and past behavior rather than conscious intentions. Understanding these determinants is key for developing effective interventions to reduce risky alcohol consumption.

Area of Science:

  • Psychology
  • Public Health
  • Behavioral Science

Background:

  • University students frequently engage in heavy episodic drinking (HED).
  • HED is linked to significant risks including injury, academic issues, and economic costs.
  • Understanding the drivers of HED is crucial for intervention development.

Purpose of the Study:

  • To investigate reasoned and implicit pathways influencing HED in Australian university students.
  • To test hypotheses derived from social cognition theories and dual-process models.
  • To identify key determinants of HED for targeted interventions.

Main Methods:

  • A two-wave correlational study with 204 Australian university students who consume alcohol.
  • Participants completed self-report measures of social cognition constructs, habit, past behavior, and implicit alcohol identity at T1.
  • HED behavior and habit were self-reported at T2, four weeks later.

Main Results:

  • Attitude and subjective norm predicted intentions; intentions and implicit alcohol identity predicted HED.
  • Past behavior and habit demonstrated direct effects on HED, attenuating other predictors.
  • Habit and past behavior significantly influenced HED through both direct and indirect pathways.

Conclusions:

  • Heavy episodic drinking in university students is predominantly governed by automatic, non-conscious processes.
  • Past behavior and established habits play a more significant role in HED than conscious intentions.
  • Interventions should consider targeting automatic processes and habit formation to effectively reduce HED.
