Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

32
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

CNS Depressants: Alcohol and Nicotine

209
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...

Cognitive Development During Adulthood

112
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Cognitive Development During Adolescence

55
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

168
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

476
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...

Area of Science:

  • Neuroscience
  • Psychology
  • Public Health

Background:

  • Adolescence is a critical period for brain development.
  • Excessive alcohol consumption during this period may have long-term neurocognitive consequences.
  • Understanding sex-specific effects is crucial for targeted interventions.

Purpose of the Study:

  • To investigate the relationship between adolescent alcohol intake (bingeing and intoxication) and neurocognitive functioning in young adulthood.
  • To determine if these associations differ between males and females.
  • To control for other substance use and illicit substance use.

Main Methods:

  • Longitudinal study of 692 Chilean adolescents (mean age 16.0 years, 54.5% female).
  • Assessed frequency of binge drinking and intoxication in adolescence.
  • Evaluated neurocognitive functions (visual memory, attention, processing speed, etc.) in young adulthood (mean age 21.2 years).

Main Results:

  • No overall effects of intoxication or bingeing on neurocognition when sexes were combined.
  • Females: Higher intoxication frequency linked to poorer visual memory, attention, processing speed, response inhibition, and cognitive flexibility.
  • Males: Higher intoxication frequency linked to better attention and processing speed; no significant effects on other domains.

Conclusions:

  • Adolescent alcohol intoxication has sex-specific effects on neurocognitive outcomes in young adulthood.
  • Females appear more vulnerable to negative cognitive impacts from frequent intoxication.
  • Further research is needed to explore the mechanisms behind these divergent sex effects.
