Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

1.5K
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Barbiturates

1.0K
Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect. A...

Sedatives and Hypnotics Drugs: Benzodiazepines

859
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

570
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Measures of Central Tendency02:16

Measures of Central Tendency

21.1K
The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

Measurement: Standard Units

79.2K
Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the measurement (a unit), and an indication of the uncertainty of the measurement. While the number and unit are explicitly represented when a quantity is written, the uncertainty is an aspect of the errors in the measurement results.

Summary

Online screening for hypnotic response is a viable tool, showing minimal reduction in responsiveness compared to offline methods. This approach can facilitate larger, more diverse psychological studies, potentially aiding in resolving the replication crisis.

Area of Science:

  • Psychology
  • Cognitive Science

Background:

  • Hypnosis and hypnotic suggestions are increasingly recognized for manipulating consciousness, including illusions, hallucinations, and delusions.
  • Widespread adoption of hypnosis is hindered by the time-intensive process of identifying individuals with varying suggestibility.

Purpose of the Study:

  • To introduce and validate an online assessment for hypnotic response.
  • To compare the psychometric properties of online versus offline hypnotic response screening.

Main Methods:

  • Development of an online tool for assessing hypnotic response.
  • Statistical comparison of scores and psychometric properties between online and offline screening methods.

Main Results:

  • Online hypnotic response screening is demonstrated to be a viable method.
  • A slight reduction in responsiveness was observed with online screening compared to offline methods.
  • The psychometric properties of the online assessment are comparable to traditional offline measures.

Conclusions:

  • Online screening for hypnotic response is practical and effective.
  • This method can enable larger-scale studies with diverse samples.
  • Online screening may contribute to addressing challenges within the current psychology replication crisis.
