Decision Making01:20

Decision Making

143
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...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

196
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,...

Drug Abuse and Addiction: Pharmacological Phenomena

515
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

131
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Reason and Intuition01:37

Reason and Intuition

6.5K
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...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

476
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Summary

Problematic pornography use (PPU) is linked to heightened impulsivity, particularly urgency, but not general executive function deficits. Cognitive performance in PPU may be impaired by sexual stimuli, not general cognitive abilities.

Area of Science:

  • Psychology
  • Neuroscience

Background:

  • Previous research on cognitive functions in Compulsive Sexual Behavior Disorder (CSBD) and problematic pornography use (PPU) yielded inconsistent findings, often using sexual stimuli.
  • The role of general executive functions in PPU, without appetitive stimuli, remains largely unexplored.

Purpose of the Study:

  • To investigate decision-making and executive function differences between individuals with high and low problematic pornography use (PPU) severity.
  • To examine the influence of general cognitive abilities and impulsivity in PPU.

Main Methods:

  • Laboratory study with N = 102 male adults.
  • Assessed trait impulsivity, executive functions (Trail Making Test, three-back working memory task), and decision making (Cards & Lottery Task - CLT).

Main Results:

  • Individuals with high PPU severity exhibited heightened impulsivity, specifically urgency and deficits in perseverance.
  • No significant differences were found in decision-making (CLT) or general executive function tasks between high and low PPU groups.

Conclusions:

  • Problematic pornography use (PPU) is associated with impulsive behaviors, particularly under emotional distress (urgency).
  • Cognitive deficits in PPU may be context-dependent, potentially exacerbated by sexual stimuli rather than reflecting general executive dysfunction.
