Summary
This study found that lorazepam, a GABAergic agonist, did not significantly alter moral judgments or implicit attitudes. However, it may influence moral sensitivity based on individual baseline levels.
Area of Science:
- Neuropsychology
- Moral Psychology
- Psychopharmacology
Background:
- Moral decision-making is influenced by emotion and personality traits like neuroticism.
- GABAergic agonists may modulate moral cognition via emotional or cognitive pathways.
Purpose of the Study:
- To investigate GABAergic modulation of moral cognition using both explicit and implicit measures.
- To assess the effects of lorazepam on moral judgments and attitudes.
Main Methods:
- Double-blind, crossover, placebo-controlled study design.
- Utilized Justice Sensitivity Inventory (JSI), moral scenario evaluations, and the morality Implicit Association Test (mIAT).
- Administered lorazepam and placebo to participants.
Main Results:
- Acute lorazepam administration did not significantly change moral judgments or implicit moral attitudes.
- Lorazepam's effect on moral sensitivity varied with baseline levels (JSI, D scores).
- Individuals with higher baseline scores showed greater reductions in moral sensitivity.
Conclusions:
- GABAergic modulation appears involved in moral cognition, but without clear behavioral outcomes.
- Individual differences in baseline moral sensitivity may influence the effects of GABAergic agents.
- Further research is needed to clarify the behavioral consequences of GABAergic modulation on moral cognition.

01:14CNS Depressants: Barbiturates and Benzodiazepines
170
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

01:29Anxiolytic Drugs: Benzodiazepines and Buspirone
349
Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

01:12Local Anesthetics: Adverse Effects
376
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:19Sedatives and Hypnotics Drugs: Benzodiazepines
138
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...

01:27CNS Depressants: Alcohol and Nicotine
154
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...

01:20Lazarus's Cognitive Appraisal Theory
86
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
